-# Documentation Guidelines
-
-All documentation must be grounded in fact, so you must not make anything up without proper evidence. When you have finished writing documentation, convey to the user what reference source, including web pages, source code, or other sources of documentation you referenced when writing each new fact in the documentation. If you cannot reference a source for anything do not include it in the pull request.
-
-## Best Practices for Documentation
-
-1. **Be Factual**: Only include information that can be verified from reliable sources.
-2. **Cite Sources**: Always reference the source of information (code, web pages, official documentation).
-3. **Be Clear and Concise**: Use simple language and avoid unnecessary jargon.
-4. **Use Examples**: Include practical examples to illustrate concepts.
-5. **Structure Properly**: Use headings, lists, and code blocks to organize information.
-6. **Keep Updated**: Ensure documentation reflects the current state of the code or system.
-
-## Documentation Process
-
-1. Research and gather information from reliable sources
-2. Draft documentation based on verified facts
-3. Review for accuracy and completeness
-4. Include references for all factual statements
-5. Submit only when all information is properly sourced
-
-Remember: If you cannot verify a piece of information, it's better to exclude it than to include potentially incorrect information.

-This repository contains the code for OpenHands, an automated AI software engineer. It has a Python backend
-(in the `openhands` directory) and React frontend (in the `frontend` directory).
-
-## General Setup:
-To set up the entire repo, including frontend and backend, run `make build`.
-You don't need to do this unless the user asks you to, or if you're trying to run the entire application.
-
-## Running OpenHands with OpenHands:
-To run the full application to debug issues:
-```bash
-export INSTALL_DOCKER=0
-export RUNTIME=local
-make build && make run FRONTEND_PORT=12000 FRONTEND_HOST=0.0.0.0 BACKEND_HOST=0.0.0.0 &> /tmp/openhands-log.txt &
-```
-
-IMPORTANT: Before making any changes to the codebase, ALWAYS run `make install-pre-commit-hooks` to ensure pre-commit hooks are properly installed.
-
-Before pushing any changes, you MUST ensure that any lint errors or simple test errors have been fixed.
-
-* If you've made changes to the backend, you should run `pre-commit run --config ./dev_config/python/.pre-commit-config.yaml` (this will run on staged files).
-* If you've made changes to the frontend, you should run `cd frontend && npm run lint:fix && npm run build ; cd ..`
-* If you've made changes to the VSCode extension, you should run `cd openhands/integrations/vscode && npm run lint:fix && npm run compile ; cd ../../..`
-
-The pre-commit hooks MUST pass successfully before pushing any changes to the repository. This is a mandatory requirement to maintain code quality and consistency.
-
-If either command fails, it may have automatically fixed some issues. You should fix any issues that weren't automatically fixed,
-then re-run the command to ensure it passes. Common issues include:
-- Mypy type errors
-- Ruff formatting issues
-- Trailing whitespace
-- Missing newlines at end of files
-
-## Git Best Practices
-
-- Prefer specific `git add <filename>` instead of `git add .` to avoid accidentally staging unintended files
-- Be especially careful with `git reset --hard` after staging files, as it will remove accidentally staged files
-- When remote has new changes, use `git fetch upstream && git rebase upstream/<branch>` on the same branch
-
-## Repository Structure
-Backend:
-- Located in the `openhands` directory
-- Testing:
-  - All tests are in `tests/unit/test_*.py`
-  - To test new code, run `poetry run pytest tests/unit/test_xxx.py` where `xxx` is the appropriate file for the current functionality
-  - Write all tests with pytest
-
-Frontend:
-- Located in the `frontend` directory
-- Prerequisites: A recent version of NodeJS / NPM
-- Setup: Run `npm install` in the frontend directory
-- Testing:
-  - Run tests: `npm run test`
-  - To run specific tests: `npm run test -- -t "TestName"`
-  - Our test framework is vitest
-- Building:
-  - Build for production: `npm run build`
-- Environment Variables:
-  - Set in `frontend/.env` or as environment variables
-  - Available variables: VITE_BACKEND_HOST, VITE_USE_TLS, VITE_INSECURE_SKIP_VERIFY, VITE_FRONTEND_PORT
-- Internationalization:
-  - Generate i18n declaration file: `npm run make-i18n`
-- Data Fetching & Cache Management:
-  - We use TanStack Query (fka React Query) for data fetching and cache management
-  - Data Access Layer: API client methods are located in `frontend/src/api` and should never be called directly from UI components - they must always be wrapped with TanStack Query
-  - Custom hooks are located in `frontend/src/hooks/query/` and `frontend/src/hooks/mutation/`
-  - Query hooks should follow the pattern use[Resource] (e.g., `useConversationMicroagents`)
-  - Mutation hooks should follow the pattern use[Action] (e.g., `useDeleteConversation`)
-  - Architecture rule: UI components → TanStack Query hooks → Data Access Layer (`frontend/src/api`) → API endpoints
-
-VSCode Extension:
-- Located in the `openhands/integrations/vscode` directory
-- Setup: Run `npm install` in the extension directory
-- Linting:
-  - Run linting with fixes: `npm run lint:fix`
-  - Check only: `npm run lint`
-  - Type checking: `npm run typecheck`
-- Building:
-  - Compile TypeScript: `npm run compile`
-  - Package extension: `npm run package-vsix`
-- Testing:
-  - Run tests: `npm run test`
-- Development Best Practices:
-  - Use `vscode.window.createOutputChannel()` for debug logging instead of `showErrorMessage()` popups
-  - Pre-commit process runs both frontend and backend checks when committing extension changes

-### Frontend
-
-#### Action Handling:
-- Actions are defined in `frontend/src/types/action-type.ts`
-- The `HANDLED_ACTIONS` array in `frontend/src/state/chat-slice.ts` determines which actions are displayed as collapsible UI elements
-- To add a new action type to the UI:
-  1. Add the action type to the `HANDLED_ACTIONS` array
-  2. Implement the action handling in `addAssistantAction` function in chat-slice.ts
-  3. Add a translation key in the format `ACTION_MESSAGE$ACTION_NAME` to the i18n files
-- Actions with `thought` property are displayed in the UI based on their action type:
-  - Regular actions (like "run", "edit") display the thought as a separate message
-  - Special actions (like "think") are displayed as collapsible elements only
-
-#### Adding User Settings:
-- To add a new user setting to OpenHands, follow these steps:
-  1. Add the setting to the frontend:
-     - Add the setting to the `Settings` type in `frontend/src/types/settings.ts`
-     - Add the setting to the `ApiSettings` type in the same file
-     - Add the setting with an appropriate default value to `DEFAULT_SETTINGS` in `frontend/src/services/settings.ts`
-     - Update the `useSettings` hook in `frontend/src/hooks/query/use-settings.ts` to map the API response
-     - Update the `useSaveSettings` hook in `frontend/src/hooks/mutation/use-save-settings.ts` to include the setting in API requests
-     - Add UI components (like toggle switches) in the appropriate settings screen (e.g., `frontend/src/routes/app-settings.tsx`)
-     - Add i18n translations for the setting name and any tooltips in `frontend/src/i18n/translation.json`
-     - Add the translation key to `frontend/src/i18n/declaration.ts`
-  2. Add the setting to the backend:
-     - Add the setting to the `Settings` model in `openhands/storage/data_models/settings.py`
-     - Update any relevant backend code to apply the setting (e.g., in session creation)
-
-### Adding New LLM Models
-
-To add a new LLM model to OpenHands, you need to update multiple files across both frontend and backend:
-
-#### Model Configuration Procedure:
-
-1. **Frontend Model Arrays** (`frontend/src/utils/verified-models.ts`):
-   - Add the model to `VERIFIED_MODELS` array (main list of all verified models)
-   - Add to provider-specific arrays based on the model's provider:
-     - `VERIFIED_OPENAI_MODELS` for OpenAI models
-     - `VERIFIED_ANTHROPIC_MODELS` for Anthropic models
-     - `VERIFIED_MISTRAL_MODELS` for Mistral models
-     - `VERIFIED_OPENHANDS_MODELS` for models available through OpenHands provider
-
-2. **Backend CLI Integration** (`openhands/cli/utils.py`):
-   - Add the model to the appropriate `VERIFIED_*_MODELS` arrays
-   - This ensures the model appears in CLI model selection
-
-3. **Backend Model List** (`openhands/utils/llm.py`):
-   - **CRITICAL**: Add the model to the `openhands_models` list (lines 57-66) if using OpenHands provider
-   - This is required for the model to appear in the frontend model selector
-   - Format: `'openhands/model-name'` (e.g., `'openhands/o3'`)
-
-4. **Backend LLM Configuration** (`openhands/llm/llm.py`):
-   - Add to feature-specific arrays based on model capabilities:
-     - `FUNCTION_CALLING_SUPPORTED_MODELS` if the model supports function calling
-     - `REASONING_EFFORT_SUPPORTED_MODELS` if the model supports reasoning effort parameters
-     - `CACHE_PROMPT_SUPPORTED_MODELS` if the model supports prompt caching
-     - `MODELS_WITHOUT_STOP_WORDS` if the model doesn't support stop words
-
-5. **Validation**:
-   - Run backend linting: `pre-commit run --config ./dev_config/python/.pre-commit-config.yaml`
-   - Run frontend linting: `cd frontend && npm run lint:fix`
-   - Run frontend build: `cd frontend && npm run build`
-
-#### Model Verification Arrays:
-
-- **VERIFIED_MODELS**: Main array of all verified models shown in the UI
-- **VERIFIED_OPENAI_MODELS**: OpenAI models (LiteLLM doesn't return provider prefix)
-- **VERIFIED_ANTHROPIC_MODELS**: Anthropic models (LiteLLM doesn't return provider prefix)
-- **VERIFIED_MISTRAL_MODELS**: Mistral models (LiteLLM doesn't return provider prefix)
-- **VERIFIED_OPENHANDS_MODELS**: Models available through OpenHands managed provider
-
-#### Model Feature Support Arrays:
-
-- **FUNCTION_CALLING_SUPPORTED_MODELS**: Models that support structured function calling
-- **REASONING_EFFORT_SUPPORTED_MODELS**: Models that support reasoning effort parameters (like o1, o3)
-- **CACHE_PROMPT_SUPPORTED_MODELS**: Models that support prompt caching for efficiency
-- **MODELS_WITHOUT_STOP_WORDS**: Models that don't support stop word parameters
-
-#### Frontend Model Integration:
-
-- Models are automatically available in the model selector UI once added to verified arrays
-- The `extractModelAndProvider` utility automatically detects provider from model arrays
-- Provider-specific models are grouped and prioritized in the UI selection
-
-#### CLI Model Integration:
-
-- Models appear in CLI provider selection based on the verified arrays
-- The `organize_models_and_providers` function groups models by provider
-- Default model selection prioritizes verified models for each provider

-size, visible or invisible disability, ethnicity, sex characteristics, gender
-identity and expression, level of experience, education, socio-economic status,
-nationality, personal appearance, race, caste, color, religion, or sexual
-identity and orientation.
-
-We pledge to act and interact in ways that contribute to an open, welcoming,
-diverse, inclusive, and healthy community.
-
-## Our Standards
-
-Examples of behavior that contributes to a positive environment for our
-community include:
-
-* Demonstrating empathy and kindness toward other people.
-* Being respectful of differing opinions, viewpoints, and experiences.
-* Giving and gracefully accepting constructive feedback.
-* Accepting responsibility and apologizing to those affected by our mistakes,
-  and learning from the experience.
-* Focusing on what is best not just for us as individuals, but for the overall
-  community.
-
-Examples of unacceptable behavior include:
-
-* The use of sexualized language or imagery, and sexual attention or advances of
-  any kind.
-* Trolling, insulting or derogatory comments, and personal or political attacks.
-* Public or private harassment.
-* Publishing others' private information, such as a physical or email address,
-  without their explicit permission.
-* Other conduct which could reasonably be considered inappropriate in a
-  professional setting.
-
-## Enforcement Responsibilities
-
-Community leaders are responsible for clarifying and enforcing our standards of
-acceptable behavior and will take appropriate and fair corrective action in
-response to any behavior that they deem inappropriate, threatening, offensive,
-or harmful.
-
-Community leaders have the right and responsibility to remove, edit, or reject
-comments, commits, code, wiki edits, issues, and other contributions that are
-not aligned to this Code of Conduct, and will communicate reasons for moderation
-decisions when appropriate.
-
-## Scope
-
-This Code of Conduct applies within all community spaces, and also applies when
-an individual is officially representing the community in public spaces.
-Examples of representing our community include using an official email address,
-posting via an official social media account, or acting as an appointed
-representative at an online or offline event.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported to the community leaders responsible for enforcement at
-contact@all-hands.dev.
-All complaints will be reviewed and investigated promptly and fairly.
-
-All community leaders are obligated to respect the privacy and security of the
-reporter of any incident.
-
-## Enforcement Guidelines
-
-Community leaders will follow these Community Impact Guidelines in determining
-the consequences for any action they deem in violation of this Code of Conduct:
-
-### 1. Correction
-
-**Community Impact**: Use of inappropriate language or other behavior deemed
-unprofessional or unwelcome in the community.
-
-**Consequence**: A private, written warning from community leaders, providing
-clarity around the nature of the violation and an explanation of why the
-behavior was inappropriate. A public apology may be requested.
-
-### 2. Warning
-
-**Community Impact**: A violation through a single incident or series of
-actions.
-
-**Consequence**: A warning with consequences for continued behavior. No
-interaction with the people involved, including unsolicited interaction with
-those enforcing the Code of Conduct, for a specified period of time. This
-includes avoiding interactions in community spaces as well as external channels
-like social media. Violating these terms may lead to a temporary or permanent
-ban.
-
-### 3. Temporary Ban
-
-**Community Impact**: A serious violation of community standards, including
-sustained inappropriate behavior.
-
-**Consequence**: A temporary ban from any sort of interaction or public
-communication with the community for a specified period of time. No public or
-private interaction with the people involved, including unsolicited interaction
-with those enforcing the Code of Conduct, is allowed during this period.
-Violating these terms may lead to a permanent ban.
-
-### 4. Permanent Ban
-
-**Community Impact**: Demonstrating a pattern of violation of community
-standards, including sustained inappropriate behavior, harassment of an
-individual, or aggression toward or disparagement of classes of individuals.
-
-**Consequence**: A permanent ban from any sort of public interaction within the
-community.
-
-### Slack and Discord Etiquettes
-
-These Slack and Discord etiquette guidelines are designed to foster an inclusive, respectful, and productive environment for all community members. By following these best practices, we ensure effective communication and collaboration while minimizing disruptions. Let’s work together to build a supportive and welcoming community!
-
-- Communicate respectfully and professionally, avoiding sarcasm or harsh language, and remember that tone can be difficult to interpret in text.
-- Use threads for specific discussions to keep channels organized and easier to follow.
-- Tag others only when their input is critical or urgent, and use @here, @channel or @everyone sparingly to minimize disruptions.
-- Be patient, as open-source contributors and maintainers often have other commitments and may need time to respond.
-- Post questions or discussions in the most relevant channel (e.g., for [slack - #general](https://openhands-ai.slack.com/archives/C06P5NCGSFP) for general topics, [slack - #questions](https://openhands-ai.slack.com/archives/C06U8UTKSAD) for queries/questions, [discord - #general](https://discord.com/channels/1222935860639563850/1222935861386018885)).
-- When asking for help or raising issues, include necessary details like links, screenshots, or clear explanations to provide context.
-- Keep discussions in public channels whenever possible to allow others to benefit from the conversation, unless the matter is sensitive or private.
-- Always adhere to [our standards](https://github.com/All-Hands-AI/OpenHands/blob/main/CODE_OF_CONDUCT.md#our-standards) to ensure a welcoming and collaborative environment.
-- If you choose to mute a channel, consider setting up alerts for topics that still interest you to stay engaged. For Slack, Go to Settings → Notifications → My Keywords to add specific keywords that will notify you when mentioned. For example, if you're here for discussions about LLMs, mute the channel if it’s too busy, but set notifications to alert you only when “LLMs” appears in messages. Also for Discord, go to the channel notifications and choose the option that best describes your need.

-## 🛠️ Becoming a Maintainer
-
-For contributors who have made significant and sustained contributions to the project, there is a possibility of joining
-the maintainer team. The process for this is as follows:
-
-1. Any contributor who has made sustained and high-quality contributions to the codebase can be nominated by any
-maintainer. If you feel that you may qualify you can reach out to any of the maintainers that have reviewed your PRs and ask if you can be nominated.
-2. Once a maintainer nominates a new maintainer, there will be a discussion period among the maintainers for at least 3 days.
-3. If no concerns are raised the nomination will be accepted by acclamation, and if concerns are raised there will be a discussion and possible vote.
-
-Note that just making many PRs does not immediately imply that you will become a maintainer. We will be looking
-at sustained high-quality contributions over a period of time, as well as good teamwork and adherence to our [Code of Conduct](./CODE_OF_CONDUCT.md).

-1. **Download and use** OpenHands, and send [issues](https://github.com/All-Hands-AI/OpenHands/issues) when you encounter something that isn't working or a feature that you'd like to see.
-2. **Send feedback** after each session by [clicking the thumbs-up thumbs-down buttons](https://docs.all-hands.dev/usage/feedback), so we can see where things are working and failing, and also build an open dataset for training code agents.
-3. **Improve the Codebase** by sending [PRs](#sending-pull-requests-to-openhands) (see details below). In particular, we have some [good first issues](https://github.com/All-Hands-AI/OpenHands/labels/good%20first%20issue) that may be ones to start on.
-
-## What Can I Build?
-Here are a few ways you can help improve the codebase.
-
-#### UI/UX
-We're always looking to improve the look and feel of the application. If you've got a small fix
-for something that's bugging you, feel free to open up a PR that changes the [`./frontend`](./frontend) directory.
-
-If you're looking to make a bigger change, add a new UI element, or significantly alter the style
-of the application, please open an issue first, or better, join the #eng-ui-ux channel in our Slack
-to gather consensus from our design team first.
-
-#### Improving the agent
-Our main agent is the CodeAct agent. You can [see its prompts here](https://github.com/All-Hands-AI/OpenHands/tree/main/openhands/agenthub/codeact_agent).
-
-Changes to these prompts, and to the underlying behavior in Python, can have a huge impact on user experience.
-You can try modifying the prompts to see how they change the behavior of the agent as you use the app
-locally, but we will need to do an end-to-end evaluation of any changes here to ensure that the agent
-is getting better over time.
-
-We use the [SWE-bench](https://www.swebench.com/) benchmark to test our agent. You can join the #evaluation
-channel in Slack to learn more.
-
-#### Adding a new agent
-You may want to experiment with building new types of agents. You can add an agent to [`openhands/agenthub`](./openhands/agenthub)
-to help expand the capabilities of OpenHands.
-
-#### Adding a new runtime
-The agent needs a place to run code and commands. When you run OpenHands on your laptop, it uses a Docker container
-to do this by default. But there are other ways of creating a sandbox for the agent.
-
-If you work for a company that provides a cloud-based runtime, you could help us add support for that runtime
-by implementing the [interface specified here](https://github.com/All-Hands-AI/OpenHands/blob/main/openhands/runtime/base.py).
-
-#### Testing
-When you write code, it is also good to write tests. Please navigate to the [`./tests`](./tests) folder to see existing test suites.
-At the moment, we have two kinds of tests: [`unit`](./tests/unit) and [`integration`](./evaluation/integration_tests). Please refer to the README for each test suite. These tests also run on GitHub's continuous integration to ensure quality of the project.
-
-## Sending Pull Requests to OpenHands
-
-You'll need to fork our repository to send us a Pull Request. You can learn more
-about how to fork a GitHub repo and open a PR with your changes in [this article](https://medium.com/swlh/forks-and-pull-requests-how-to-contribute-to-github-repos-8843fac34ce8).
-
-### Pull Request title
-As described [here](https://github.com/commitizen/conventional-commit-types/blob/master/index.json), a valid PR title should begin with one of the following prefixes:
-
-- `feat`: A new feature
-- `fix`: A bug fix
-- `docs`: Documentation only changes
-- `style`: Changes that do not affect the meaning of the code (white space, formatting, missing semicolons, etc.)
-- `refactor`: A code change that neither fixes a bug nor adds a feature
-- `perf`: A code change that improves performance
-- `test`: Adding missing tests or correcting existing tests
-- `build`: Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)
-- `ci`: Changes to our CI configuration files and scripts (example scopes: Travis, Circle, BrowserStack, SauceLabs)
-- `chore`: Other changes that don't modify src or test files
-- `revert`: Reverts a previous commit
-
-For example, a PR title could be:
-- `refactor: modify package path`
-- `feat(frontend): xxxx`, where `(frontend)` means that this PR mainly focuses on the frontend component.
-
-You may also check out previous PRs in the [PR list](https://github.com/All-Hands-AI/OpenHands/pulls).
-
-### Pull Request description
-- If your PR is small (such as a typo fix), you can go brief.
-- If it contains a lot of changes, it's better to write more details.
-
-If your changes are user-facing (e.g. a new feature in the UI, a change in behavior, or a bugfix)
-please include a short message that we can add to our changelog.
-
-## How to Make Effective Contributions
-
-### Opening Issues
-
-If you notice any bugs or have any feature requests please open them via the [issues page](https://github.com/All-Hands-AI/OpenHands/issues). We will triage based on how critical the bug is or how potentially useful the improvement is, discuss, and implement the ones that the community has interest/effort for.
-
-Further, if you see an issue you like, please leave a "thumbs-up" or a comment, which will help us prioritize.
-
-### Making Pull Requests
-
-We're generally happy to consider all pull requests with the evaluation process varying based on the type of change:
-
-#### For Small Improvements
-
-Small improvements with few downsides are typically reviewed and approved quickly.
-One thing to check when making changes is to ensure that all continuous integration tests pass, which you can check before getting a review.
-
-#### For Core Agent Changes
-
-We need to be more careful with changes to the core agent, as it is imperative to maintain high quality. These PRs are evaluated based on three key metrics:
-
-1. **Accuracy**
-2. **Efficiency**
-3. **Code Complexity**
-
-If it improves accuracy, efficiency, or both with only a minimal change to code quality, that's great we're happy to merge it in!
-If there are bigger tradeoffs (e.g. helping efficiency a lot and hurting accuracy a little) we might want to put it behind a feature flag.
-Either way, please feel free to discuss on github issues or slack, and we will give guidance and preliminary feedback.

-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade

-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
-
-   END OF TERMS AND CONDITIONS
-
-   APPENDIX: How to apply the Apache License to your work.
-
-      To apply the Apache License to your work, attach the following
-      boilerplate notice, with the fields enclosed by brackets "[]"
-      replaced with your own identifying information. (Don't include
-      the brackets!)  The text should be enclosed in the appropriate

-# Development Guide
-
-This guide is for people working on OpenHands and editing the source code.
-If you wish to contribute your changes, check out the
-[CONTRIBUTING.md](https://github.com/All-Hands-AI/OpenHands/blob/main/CONTRIBUTING.md)
-on how to clone and setup the project initially before moving on. Otherwise,
-you can clone the OpenHands project directly.
-
-## Start the Server for Development
-
-### 1. Requirements
-
-- Linux, Mac OS, or [WSL on Windows](https://learn.microsoft.com/en-us/windows/wsl/install) [Ubuntu >= 22.04]
-- [Docker](https://docs.docker.com/engine/install/) (For those on MacOS, make sure to allow the default Docker socket to be used from advanced settings!)
-- [Python](https://www.python.org/downloads/) = 3.12
-- [NodeJS](https://nodejs.org/en/download/package-manager) >= 22.x
-- [Poetry](https://python-poetry.org/docs/#installing-with-the-official-installer) >= 1.8
-- OS-specific dependencies:
-  - Ubuntu: build-essential => `sudo apt-get install build-essential python3.12-dev`
-  - WSL: netcat => `sudo apt-get install netcat`
-
-Make sure you have all these dependencies installed before moving on to `make build`.
-
-#### Dev container
-
-There is a [dev container](https://containers.dev/) available which provides a
-pre-configured environment with all the necessary dependencies installed if you
-are using a [supported editor or tool](https://containers.dev/supporting). For
-example, if you are using Visual Studio Code (VS Code) with the
-[Dev Containers](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers)
-extension installed, you can open the project in a dev container by using the
-_Dev Container: Reopen in Container_ command from the Command Palette
-(Ctrl+Shift+P).
-
-#### Develop without sudo access
-
-If you want to develop without system admin/sudo access to upgrade/install `Python` and/or `NodeJS`, you can use
-`conda` or `mamba` to manage the packages for you:
-
-```bash
-# Download and install Mamba (a faster version of conda)
-curl -L -O "https://github.com/conda-forge/miniforge/releases/latest/download/Miniforge3-$(uname)-$(uname -m).sh"
-bash Miniforge3-$(uname)-$(uname -m).sh
-
-# Install Python 3.12, nodejs, and poetry
-mamba install python=3.12
-mamba install conda-forge::nodejs
-mamba install conda-forge::poetry
-```
-
-### 2. Build and Setup The Environment
-
-Begin by building the project which includes setting up the environment and installing dependencies. This step ensures
-that OpenHands is ready to run on your system:
-
-```bash
-make build
-```
-
-### 3. Configuring the Language Model
-
-OpenHands supports a diverse array of Language Models (LMs) through the powerful [litellm](https://docs.litellm.ai) library.
-
-To configure the LM of your choice, run:
-
-```bash
-make setup-config
-```
-
-This command will prompt you to enter the LLM API key, model name, and other variables ensuring that OpenHands is
-tailored to your specific needs. Note that the model name will apply only when you run headless. If you use the UI,
-please set the model in the UI.
-
-Note: If you have previously run OpenHands using the docker command, you may have already set some environment
-variables in your terminal. The final configurations are set from highest to lowest priority:
-Environment variables > config.toml variables > default variables
-
-**Note on Alternative Models:**
-See [our documentation](https://docs.all-hands.dev/usage/llms) for recommended models.
-
-### 4. Running the application
-
-#### Option A: Run the Full Application
-
-Once the setup is complete, this command starts both the backend and frontend servers, allowing you to interact with OpenHands:
-
-```bash
-make run
-```
-
-#### Option B: Individual Server Startup
-
-- **Start the Backend Server:** If you prefer, you can start the backend server independently to focus on
-backend-related tasks or configurations.
-
-  ```bash
-  make start-backend
-  ```
-
-- **Start the Frontend Server:** Similarly, you can start the frontend server on its own to work on frontend-related
-components or interface enhancements.
-  ```bash
-  make start-frontend
-  ```
-
-### 5. Running OpenHands with OpenHands
-
-You can use OpenHands to develop and improve OpenHands itself! This is a powerful way to leverage AI assistance for contributing to the project.
-
-#### Quick Start
-
-1. **Build and run OpenHands:**
-   ```bash
-   export INSTALL_DOCKER=0
-   export RUNTIME=local
-   make build && make run
-   ```
-
-2. **Access the interface:**
-   - Local development: http://localhost:3001
-   - Remote/cloud environments: Use the appropriate external URL
-
-3. **Configure for external access (if needed):**
-   ```bash
-   # For external access (e.g., cloud environments)
-   make run FRONTEND_PORT=12000 FRONTEND_HOST=0.0.0.0 BACKEND_HOST=0.0.0.0
-   ```
-
-### 6. LLM Debugging
-
-If you encounter any issues with the Language Model (LM) or you're simply curious, export DEBUG=1 in the environment and restart the backend.
-OpenHands will log the prompts and responses in the logs/llm/CURRENT_DATE directory, allowing you to identify the causes.
-
-### 7. Help
-
-Need help or info on available targets and commands? Use the help command for all the guidance you need with OpenHands.
-
-```bash
-make help
-```
-
-### 8. Testing
-
-To run tests, refer to the following:
-
-#### Unit tests
-
-```bash
-poetry run pytest ./tests/unit/test_*.py
-```
-
-### 9. Add or update dependency
-
-1. Add your dependency in `pyproject.toml` or use `poetry add xxx`.
-2. Update the poetry.lock file via `poetry lock --no-update`.
-
-### 10. Use existing Docker image
-
-To reduce build time (e.g., if no changes were made to the client-runtime component), you can use an existing Docker
-container image by setting the SANDBOX_RUNTIME_CONTAINER_IMAGE environment variable to the desired Docker image.
-
-Example: `export SANDBOX_RUNTIME_CONTAINER_IMAGE=ghcr.io/all-hands-ai/runtime:0.53-nikolaik`
-
-## Develop inside Docker container
-
-TL;DR
-
-```bash
-make docker-dev
-```
-
-See more details [here](./containers/dev/README.md).
-
-If you are just interested in running `OpenHands` without installing all the required tools on your host.
-
-```bash
-make docker-run
-```
-
-If you do not have `make` on your host, run:
-
-```bash
-cd ./containers/dev
-./dev.sh
-```
-
-You do need [Docker](https://docs.docker.com/engine/install/) installed on your host though.

-# Issue Triage
-These are the procedures and guidelines on how issues are triaged in this repo by the maintainers.
-
-## General
-* All issues must be tagged with **enhancement**, **bug** or **troubleshooting/help**.
-* Issues may be tagged with what it relates to (**agent quality**, **resolver**, **CLI**, etc.).
-
-## Severity
-* **High**: High visibility issues or affecting many users.
-* **Critical**: Affecting all users or potential security issues.
-
-## Difficulty
-* Issues with low implementation difficulty may be tagged with **good first issue**.
-
-## Not Enough Information
-* User is asked to provide more information (logs, how to reproduce, etc.) when the issue is not clear.
-* If an issue is unclear and the author does not provide more information or respond to a request,
-the issue may be closed as **not planned** (Usually after a week).
-
-## Multiple Requests/Fixes in One Issue
-* These issues will be narrowed down to one request/fix so the issue is more easily tracked and fixed.
-* Issues may be broken down into multiple issues if required.
-
-## Stale and Auto Closures
-* In order to keep a maintainable backlog, issues that have no activity within 30 days are automatically marked as **Stale**.
-* If issues marked as **Stale** continue to have no activity for 7 more days, they will automatically be closed as not planned.
-* Issues may be reopened by maintainers if deemed important.

-
-Welcome to OpenHands (formerly OpenDevin), a platform for software development agents powered by AI.
-
-OpenHands agents can do anything a human developer can: modify code, run commands, browse the web,
-call APIs, and yes—even copy code snippets from StackOverflow.
-
-Learn more at [docs.all-hands.dev](https://docs.all-hands.dev), or [sign up for OpenHands Cloud](https://app.all-hands.dev) to get started.
-
-> [!IMPORTANT]
-> Using OpenHands for work? We'd love to chat! Fill out
-> [this short form](https://docs.google.com/forms/d/e/1FAIpQLSet3VbGaz8z32gW9Wm-Grl4jpt5WgMXPgJ4EDPVmCETCBpJtQ/viewform)
-> to join our Design Partner program, where you'll get early access to commercial features and the opportunity to provide input on our product roadmap.
-
-![App screenshot](./docs/static/img/screenshot.png)
-
-## ☁️ OpenHands Cloud
-The easiest way to get started with OpenHands is on [OpenHands Cloud](https://app.all-hands.dev),
-which comes with $20 in free credits for new users.
-
-## 💻 Running OpenHands Locally
-
-### Option 1: CLI Launcher (Recommended)
-
-The easiest way to run OpenHands locally is using the CLI launcher with [uv](https://docs.astral.sh/uv/). This provides better isolation from your current project's virtual environment and is required for OpenHands' default MCP servers.
-
-**Install uv** (if you haven't already):
-
-See the [uv installation guide](https://docs.astral.sh/uv/getting-started/installation/) for the latest installation instructions for your platform.
-
-**Launch OpenHands**:
-```bash
-# Launch the GUI server
-uvx --python 3.12 --from openhands-ai openhands serve
-
-# Or launch the CLI
-uvx --python 3.12 --from openhands-ai openhands
-```
-
-You'll find OpenHands running at [http://localhost:3000](http://localhost:3000) (for GUI mode)!
-
-### Option 2: Docker
-
-<details>
-<summary>Click to expand Docker command</summary>
-
-You can also run OpenHands directly with Docker:
-
-```bash
-docker pull docker.all-hands.dev/all-hands-ai/runtime:0.53-nikolaik
-
-docker run -it --rm --pull=always \
-    -e SANDBOX_RUNTIME_CONTAINER_IMAGE=docker.all-hands.dev/all-hands-ai/runtime:0.53-nikolaik \
-    -e LOG_ALL_EVENTS=true \
-    -v /var/run/docker.sock:/var/run/docker.sock \
-    -v ~/.openhands:/.openhands \
-    -p 3000:3000 \
-    --add-host host.docker.internal:host-gateway \
-    --name openhands-app \
-    docker.all-hands.dev/all-hands-ai/openhands:0.53
-```
-
-</details>
-
-> **Note**: If you used OpenHands before version 0.44, you may want to run `mv ~/.openhands-state ~/.openhands` to migrate your conversation history to the new location.
-
-> [!WARNING]
-> On a public network? See our [Hardened Docker Installation Guide](https://docs.all-hands.dev/usage/runtimes/docker#hardened-docker-installation)
-> to secure your deployment by restricting network binding and implementing additional security measures.
-
-### Getting Started
-
-When you open the application, you'll be asked to choose an LLM provider and add an API key.
-[Anthropic's Claude Sonnet 4](https://www.anthropic.com/api) (`anthropic/claude-sonnet-4-20250514`)
-works best, but you have [many options](https://docs.all-hands.dev/usage/llms).
-
-See the [Running OpenHands](https://docs.all-hands.dev/usage/installation) guide for
-system requirements and more information.
-
-## 💡 Other ways to run OpenHands
-
-> [!WARNING]
-> OpenHands is meant to be run by a single user on their local workstation.
-> It is not appropriate for multi-tenant deployments where multiple users share the same instance. There is no built-in authentication, isolation, or scalability.
->
-> If you're interested in running OpenHands in a multi-tenant environment, check out the source-available, commercially-licensed
-> [OpenHands Cloud Helm Chart](https://github.com/all-Hands-AI/OpenHands-cloud)
-
-You can [connect OpenHands to your local filesystem](https://docs.all-hands.dev/usage/runtimes/docker#connecting-to-your-filesystem),
-interact with it via a [friendly CLI](https://docs.all-hands.dev/usage/how-to/cli-mode),
-run OpenHands in a scriptable [headless mode](https://docs.all-hands.dev/usage/how-to/headless-mode),
-or run it on tagged issues with [a github action](https://docs.all-hands.dev/usage/how-to/github-action).
-
-Visit [Running OpenHands](https://docs.all-hands.dev/usage/installation) for more information and setup instructions.
-
-If you want to modify the OpenHands source code, check out [Development.md](https://github.com/All-Hands-AI/OpenHands/blob/main/Development.md).

-# Tool Decoupling Refactoring Plan
-
-## Current State Analysis
-
-**Where we are:**
-- New `openhands/tools/` module with unified Tool architecture (✅ committed)
-- Existing tools scattered in `openhands/agenthub/codeact_agent/tools/` (old approach)
-- Function calling logic hardcoded in `function_calling.py` with manual validation
-- Multiple agents (codeact, loc, readonly) each have their own function_calling.py
-- Tool schemas defined as dictionaries in individual tool files
-
-**Key Integration Points:**
-1. `openhands/agenthub/codeact_agent/function_calling.py` - main function call processor
-2. `openhands/agenthub/codeact_agent/codeact_agent.py` - imports tools for schema generation
-3. `openhands/agenthub/loc_agent/function_calling.py` - similar pattern
-4. `openhands/agenthub/readonly_agent/function_calling.py` - similar pattern
-
-## Target State
-
-**Where we need to get to:**
-- All agents use the new Tool classes for consistent behavior
-- Function calling delegates to `Tool.validate_function_call()` for parameter validation
-- Tool schemas come from `Tool.get_schema()`
-- Action creation remains in function_calling.py (simple, no over-abstraction)
-- Remove duplicated tool logic across agents
-- **No registry needed** - agents directly import and use the tools they need
-
-## Minimal Refactoring Strategy
-
-### Phase 1: Create Bridge Layer (Non-breaking)
-**Goal:** Make new tools work alongside existing system without breaking anything
-
-1. **Create tool adapter in function_calling.py**
-   - Add import for new `openhands.tools` (BashTool, FileEditorTool, etc.)
-   - Create helper function `validate_with_new_tools()` that attempts new tool validation
-   - Fall back to existing hardcoded logic if tool not found
-   - This allows gradual migration without breaking existing functionality
-
-2. **Update tool imports in codeact_agent.py**
-   - Import new Tool classes alongside existing tool imports
-   - Modify `get_tools()` method to include schemas from both old and new tools
-   - Ensure no duplicate tool names
-
-### Phase 2: Migrate Core Tools (One by one)
-**Goal:** Replace existing tools with new implementations
-
-1. **Start with bash tool (lowest risk)**
-   - Update function_calling.py to use BashTool for execute_bash calls
-   - Remove old bash tool logic once confirmed working
-   - Keep old bash.py file temporarily for reference
-
-2. **Migrate str_replace_editor tool**
-   - Update function_calling.py to use FileEditorTool
-   - Remove complex str_replace_editor logic from function_calling.py
-   - Keep old str_replace_editor.py temporarily
-
-3. **Migrate remaining tools one by one**
-   - finish, browser, think, ipython, condensation_request
-   - Each migration should be a separate commit for easy rollback
-
-### Phase 3: Clean Up (Remove old code)
-**Goal:** Remove duplicate/obsolete code
-
-1. **Remove old tool files**
-   - Delete `openhands/agenthub/codeact_agent/tools/` directory
-   - Update imports in codeact_agent.py
-
-2. **Simplify function_calling.py**
-   - Remove all hardcoded tool logic
-   - Replace with simple registry lookup and delegation
-   - Should be ~50 lines instead of ~250 lines
-
-### Phase 4: Extend to Other Agents (Optional)
-**Goal:** Apply same pattern to loc_agent and readonly_agent
-
-1. **Update loc_agent and readonly_agent**
-   - Replace their function_calling.py with registry-based approach
-   - Reuse same tool implementations
-
-## Implementation Details
-
-### Bridge Function (Phase 1)
-```python
-def validate_with_new_tools(tool_call):
-    """Try new tool classes for validation, fall back to old logic"""
-    from openhands.tools import BashTool, FileEditorTool
-
-    # Map tool names to tool instances
-    tools = {
-        'execute_bash': BashTool(),
-        'str_replace_editor': FileEditorTool(),
-    }
-
-    tool = tools.get(tool_call.function.name)
-    if tool:
-        try:
-            return tool.validate_function_call(tool_call.function)
-        except ToolValidationError as e:
-            raise FunctionCallValidationError(str(e))
-
-    # Fall back to existing hardcoded validation
-    return None  # Signal to use old logic
-```
-
-### Simplified function_calling.py (Phase 3)
-```python
-def response_to_actions(response: ModelResponse, mcp_tool_names: list[str] | None = None) -> list[Action]:
-    """Convert LLM response to OpenHands actions using new tool classes"""
-    from openhands.tools import BashTool, FileEditorTool
-
-    # Create tool instances (could be module-level for efficiency)
-    tools = {
-        'execute_bash': BashTool(),
-        'str_replace_editor': FileEditorTool(),
-    }
-
-    actions = []
-    # ... existing response parsing logic ...
-
-    for tool_call in assistant_msg.tool_calls:
-        tool = tools.get(tool_call.function.name)
-        if tool:
-            # Validate parameters using tool
-            try:
-                validated_params = tool.validate_function_call(tool_call.function)
-            except ToolValidationError as e:
-                raise FunctionCallValidationError(str(e))
-
-            # Create action based on tool type (simple logic remains here)
-            if tool_call.function.name == 'execute_bash':
-                action = CmdRunAction(command=validated_params['command'], ...)
-            elif tool_call.function.name == 'str_replace_editor':
-                action = FileEditAction(path=validated_params['path'], ...)
-            # ... etc for other tools
-
-            actions.append(action)
-        elif mcp_tool_names and tool_call.function.name in mcp_tool_names:
-            # Handle MCP tools
-            actions.append(MCPAction(...))
-        else:
-            raise FunctionCallNotExistsError(f'Tool {tool_call.function.name} not found')
-
-    return actions
-```
-
-## Risk Mitigation
-
-1. **Incremental approach** - Each phase can be tested independently
-2. **Backward compatibility** - Bridge layer ensures nothing breaks during transition
-3. **Easy rollback** - Each tool migration is a separate commit
-4. **Minimal changes** - Don't touch agent logic, only function calling layer
-5. **Keep it simple** - Don't over-engineer, just replace existing functionality
-
-## Success Criteria
-
-- [ ] All existing tests pass
-- [ ] Function calling behavior unchanged from user perspective
-- [ ] Tool logic consolidated in single location
-- [ ] Easy to add new tools by extending Tool base class
-- [ ] Reduced code duplication across agents
-- [ ] Cleaner, more maintainable codebase
-
-## Files to Modify
-
-**Phase 1:**
-- `openhands/agenthub/codeact_agent/function_calling.py` (add bridge)
-- `openhands/agenthub/codeact_agent/codeact_agent.py` (import registry)
-
-**Phase 2:**
-- `openhands/agenthub/codeact_agent/function_calling.py` (migrate tools one by one)
-
-**Phase 3:**
-- `openhands/agenthub/codeact_agent/function_calling.py` (simplify)
-- Remove `openhands/agenthub/codeact_agent/tools/` directory
-
-**Phase 4 (Optional):**
-- `openhands/agenthub/loc_agent/function_calling.py`
-- `openhands/agenthub/readonly_agent/function_calling.py`
-
-This plan prioritizes **working incrementally** while **maintaining stability** throughout the refactoring process.

-# OpenHands Tool Decoupling - Complete Implementation Plan
-
-## 🎯 Goal
-Decouple AI agent tools into their own classes to encapsulate tool definitions, error validation, and response interpretation separate from regular agent LLM response processing.
-
-## 📊 Current Status: CRITICAL MILESTONE ACHIEVED ✅
-
-**function_calling.py Migration Complete**: Successfully migrated CodeActAgent to use unified tool validation for all 4 core tools!
-
-### 🏗️ Architecture Summary
-- **CodeActAgent**: 4 base tools (BashTool, FileEditorTool, BrowserTool, FinishTool)
-- **ReadOnlyAgent**: Inherits FinishTool + adds 3 safe tools (ViewTool, GrepTool, GlobTool)
-- **LocAgent**: Inherits all CodeAct tools + adds 3 search tools (SearchEntityTool, SearchRepoTool, ExploreStructureTool)
-
-### 🚀 Migration Achievement: function_calling.py Complete
-- ✅ **Fixed legacy tool import conflicts** with proper aliasing (LegacyBrowserTool, LegacyFinishTool)
-- ✅ **Updated BrowserTool interface** to match legacy (code parameter instead of action)
-- ✅ **All 4 core tools using unified validation**:
-  - BashTool: `validate_parameters()` with proper error handling
-  - FinishTool: `validate_parameters()` with parameter mapping (summary/outputs)
-  - FileEditorTool: `validate_parameters()` with command handling (view/edit)
-  - BrowserTool: `validate_parameters()` with code parameter validation
-- ✅ **Fixed tool name constant references** throughout function_calling.py
-- ✅ **Created comprehensive integration tests** verifying tool validation works
-- ✅ **Maintained backward compatibility** with legacy fallback paths
-
-### 🧪 Testing Status
-- **192 total tests** (all passing)
-- **Integration tests passing** for all 4 core tools
-- **163 original tests**: Base Tool class, validation, error handling, inheritance patterns
-- **29 new LocAgent tests**: Complete coverage of search tools and inheritance
-
-### 🔧 Implementation Status
-- ✅ **Tool base class** with abstract methods and validation framework
-- ✅ **CodeAct tools** with full parameter validation and schema generation
-- ✅ **ReadOnly tools** with inheritance pattern and safety validation
-- ✅ **LocAgent tools** with complex parameter validation and search capabilities
-- ✅ **Comprehensive test suite** covering all tools and edge cases
-- ✅ **CodeActAgent function_calling.py migration** with unified tool validation
-
-## Architecture Decision: Agent-Specific Tool Organization
-
-After exploring the codebase, we discovered that **agent-specific tool organization** is the correct approach because:
-
-1. **CodeActAgent** is the base agent with comprehensive tools (bash, file editing, browsing, etc.)
-2. **ReadOnlyAgent** and **LocAgent** inherit from CodeActAgent but completely override `_get_tools()`
-3. Each agent has its own `tools/` directory and `function_calling.py` module
-4. Child agents can selectively inherit parent tools and add their own
-

-
-## Detailed Implementation Plan
-
-### Phase 2: Testing & Integration (CURRENT)
-
-#### 2.1 Comprehensive Unit Tests (IMMEDIATE)
-Create `tests/unit/tools/` with complete test coverage:
-
-**Base Infrastructure Tests:**
-- `test_base_tool.py` - Tool base class, validation, error handling
-- `test_tool_inheritance.py` - Agent inheritance patterns
-

-- Gradual migration: new tools alongside existing ones
-- Validation layer that uses new Tool classes
-
-#### 2.3 Integration Points
-- Update `openhands/agenthub/codeact_agent/function_calling.py`
-- Update `openhands/agenthub/readonly_agent/function_calling.py`
-- Ensure backward compatibility during transition
-
-### Phase 3: Full Migration
-
-#### 3.1 LocAgent Tool Organization ✅
-```
-openhands/agenthub/loc_agent/tools/unified/
-├── __init__.py                    # Inherit from CodeAct + add search tools
-├── search_entity_tool.py          # SearchEntityTool for entity retrieval
-├── search_repo_tool.py            # SearchRepoTool for code snippet search
-└── explore_structure_tool.py      # ExploreStructureTool for dependency analysis
-```
-
-#### 3.2 Complete Migration
-- Replace all old tool definitions with new unified classes
-- Update all function_calling.py modules
-- Remove legacy tool code
-- Update agent `_get_tools()` methods to use new architecture
-
-#### 3.3 Cleanup & Documentation

-
-## Key Benefits of This Architecture
-
-1. **Encapsulation**: Tool logic separated from agent processing
-2. **Inheritance**: Child agents can reuse parent tools selectively
-3. **Validation**: Centralized parameter validation with clear error messages
-4. **Extensibility**: Easy to add new tools or modify existing ones
-5. **Type Safety**: Proper typing and schema validation
-6. **Testing**: Each tool can be unit tested independently
-
-## Testing Strategy
-
-### Unit Test Coverage Requirements
-- **Schema Generation**: Verify correct LiteLLM-compatible schemas
-- **Parameter Validation**: Test all validation rules and edge cases
-- **Error Handling**: Test all error conditions and messages
-- **Inheritance**: Verify child agents can inherit and extend parent tools
-- **Integration**: Test function call processing end-to-end
-
-### Test Categories
-1. **Positive Tests**: Valid inputs produce expected outputs
-2. **Negative Tests**: Invalid inputs produce appropriate errors
-3. **Edge Cases**: Boundary conditions, empty values, type mismatches
-4. **Integration Tests**: Agent-tool interaction, function calling flow
-
-## Migration Strategy
-
-1. **Parallel Implementation**: New tools alongside existing ones
-2. **Gradual Adoption**: Migrate one agent at a time
-3. **Backward Compatibility**: Maintain existing functionality during transition
-4. **Validation**: Comprehensive testing at each step
-5. **Cleanup**: Remove old code only after full migration
-
-## Success Criteria
-
-- [ ] All agents use unified tool architecture
-- [ ] 100% test coverage for tool functionality
-- [ ] No regression in existing functionality
-- [ ] Clear separation of concerns between tools and agents
-- [ ] Easy to add new tools or modify existing ones
-- [ ] Comprehensive error handling and validation

+    The Code Act Agent is a minimalist agent.
+    The agent works by passing the model a list of action-observation pairs and prompting the model to take the next step.
+
+    ### Overview
+
+    This agent implements the CodeAct idea ([paper](https://arxiv.org/abs/2402.01030), [tweet](https://twitter.com/xingyaow_/status/1754556835703751087)) that consolidates LLM agents’ **act**ions into a unified **code** action space for both *simplicity* and *performance* (see paper for more details).
+
+    The conceptual idea is illustrated below. At each turn, the agent can:
+
+    1. **Converse**: Communicate with humans in natural language to ask for clarification, confirmation, etc.
+    2. **CodeAct**: Choose to perform the task by executing code
+    - Execute any valid Linux `bash` command
+    - Execute any valid `Python` code with [an interactive Python interpreter](https://ipython.org/). This is simulated through `bash` command, see plugin system below for more details.

+# Task
+You're a diligent software engineer AI. You can't see, draw, or interact with a
+browser, but you can read and write files, and you can run commands, and you can think.
+
+You've been given the following task:
+
+%(task)s
+
+## Plan
+As you complete this task, you're building a plan and keeping
+track of your progress. Here's a JSON representation of your plan:
+
+%(plan)s
+
+
+%(plan_status)s
+
+You're responsible for managing this plan and the status of tasks in
+it, by using the `add_task` and `modify_task` actions described below.
+
+If the History below contradicts the state of any of these tasks, you
+MUST modify the task using the `modify_task` action described below.
+
+Be sure NOT to duplicate any tasks. Do NOT use the `add_task` action for
+a task that's already represented. Every task must be represented only once.
+
+Tasks that are sequential MUST be siblings. They must be added in order
+to their parent task.
+
+If you mark a task as 'completed', 'verified', or 'abandoned',
+all non-abandoned subtasks will be marked the same way.
+So before closing a task this way, you MUST not only be sure that it has
+been completed successfully--you must ALSO be sure that all its subtasks
+are ready to be marked the same way.
+
+If, and only if, ALL tasks have already been marked verified,
+you MUST respond with the `finish` action.
+
+## History
+Here is a recent history of actions you've taken in service of this plan,
+as well as observations you've made. This only includes the MOST RECENT
+ten actions--more happened before that.
+
+%(history)s
+
+
+Your most recent action is at the bottom of that history.
+
+## Action
+What is your next thought or action? Your response must be in JSON format.
+
+It must be an object, and it must contain two fields:
+* `action`, which is one of the actions below

-# Develop in Docker
-
-> [!WARNING]
-> This is not officially supported and may not work.
-
-Install [Docker](https://docs.docker.com/engine/install/) on your host machine and run:
-
-```bash
-make docker-dev
-# same as:
-cd ./containers/dev
-./dev.sh
-```
-
-It could take some time if you are running for the first time as Docker will pull all the  tools required for building OpenHands. The next time you run again, it should be instant.
-
-## Build and run
-
-If everything goes well, you should be inside a container after Docker finishes building the `openhands:dev` image similar to the following:
-
-```bash
-Build and run in Docker ...
-root@93fc0005fcd2:/app#
-```
-
-You may now proceed with the normal [build and run](../../Development.md) workflow as if you were on the host.
-
-## Make changes
-
-The source code on the host is mounted as `/app` inside docker. You may edit the files as usual either inside the Docker container or on your host with your favorite IDE/editors.
-
-The following are also mapped as readonly from your host:
-
-```yaml
-# host credentials
-- $HOME/.git-credentials:/root/.git-credentials:ro
-- $HOME/.gitconfig:/root/.gitconfig:ro
-- $HOME/.npmrc:/root/.npmrc:ro
-```
-
-## VSCode
-
-Alternatively, if you use VSCode, you could also [attach to the running container](https://code.visualstudio.com/docs/devcontainers/attach-container).
-
-See details for [developing in docker](https://code.visualstudio.com/docs/devcontainers/containers) or simply ask `OpenHands` ;-)
-
-## Rebuild dev image
-
-You could optionally pass additional options to the build script.
-
-```bash
-make docker-dev OPTIONS="--build"
-# or
-./containers/dev/dev.sh --build
-```
-

-that depends on the `base_image` **AND** a [Python source distribution](https://docs.python.org/3.10/distutils/sourcedist.html) that is based on the current commit of `openhands`.
-
-The following command will generate a `Dockerfile` file for `nikolaik/python-nodejs:python3.12-nodejs22` (the default base image), an updated `config.sh` and the runtime source distribution files/folders into `containers/runtime`:
