+
+# Open a Pull Request
+
+## Step 1: Pre-flight checks
+
+Before opening the PR:
+
+1. Ensure all changes are committed
+2. Ensure the branch is pushed to the remote (`git push -u origin <branch>`)
+3. Run linters/formatters across the whole repo (not just changed files) and commit any fixes
+
+## Step 2: Test coverage
+
+**This is critical.** Before opening the PR, verify:
+
+### Existing behavior is not broken
+- Identify which modules/components your changes touch
+- Run the existing test suites for those areas
+- If tests fail, fix them before opening the PR — do not open a PR with known regressions
+
+### New behavior has test coverage
+- Every new feature, endpoint, or behavior change needs tests
+- If you added a new block, add tests for that block
+- If you changed API behavior, add or update API tests
+- If you changed frontend behavior, verify it doesn't break existing flows
+
+If you cannot run the full test suite locally, note which tests you ran and which you couldn't in the test plan.
+
+## Step 3: Create the PR using the repo template
+
+Read the canonical PR template at `.github/PULL_REQUEST_TEMPLATE.md` and use it **verbatim** as your PR body:
+
+1. Read the template: `cat .github/PULL_REQUEST_TEMPLATE.md`
+2. Preserve the exact section titles and formatting, including:
+   - `### Why / What / How`
+   - `### Changes 🏗️`
+   - `### Checklist 📋`
+3. Replace HTML comment prompts (`<!-- ... -->`) with actual content; do not leave them in
+4. **Do not pre-check boxes** — leave all checkboxes as `- [ ]` until each step is actually completed
+5. Do not alter the template structure, rename sections, or remove any checklist items
+
+**PR title must use conventional commit format** (e.g., `feat(backend): add new block`, `fix(frontend): resolve routing bug`, `dx(skills): update PR workflow`). See CLAUDE.md for the full list of scopes.
+
+Use `gh pr create` with the base branch (defaults to `dev` if no `[base-branch]` was provided). Use `--body-file` to avoid shell interpretation of backticks and special characters:
+
+```bash
+BASE_BRANCH="${BASE_BRANCH:-dev}"
+PR_BODY=$(mktemp)
+cat > "$PR_BODY" << 'PREOF'
+<filled-in template from .github/PULL_REQUEST_TEMPLATE.md>
+PREOF
+gh pr create --base "$BASE_BRANCH" --title "<type>(scope): short description" --body-file "$PR_BODY"
+rm "$PR_BODY"
+```
+
+## Step 4: Review workflow
+
+### If you have a workspace that allows testing (docker, running backend, etc.)
+- Run `/pr-test` to do E2E manual testing of the PR using docker compose, agent-browser, and API calls. This is the most thorough way to validate your changes before review.
+- After testing, run `/pr-review` to self-review the PR for correctness, security, code quality, and testing gaps before requesting human review.
+
+### If you do NOT have a workspace that allows testing
+This is common for agents running in worktrees without a full stack. In this case:
+
+1. Run `/pr-review` locally to catch obvious issues before pushing
+2. **Comment `/review` on the PR** after creating it to trigger the review bot
+3. **Poll for the review** rather than blindly waiting — check for new review comments every 30 seconds using `gh api repos/Significant-Gravitas/AutoGPT/pulls/{N}/reviews --paginate` and the GraphQL inline threads query. The bot typically responds within 30 minutes, but polling lets the agent react as soon as it arrives.
+4. Do NOT proceed or merge until the bot review comes back
+5. Address any issues the bot raises — use `/pr-address` which has a full polling loop with CI + comment tracking
+
+```bash
+# After creating the PR:
+PR_NUMBER=$(gh pr view --json number -q .number)
+gh pr comment "$PR_NUMBER" --body "/review"
+# Then use /pr-address to poll for and address the review when it arrives
+```
+
+## Step 5: Address review feedback
+
+Once the review bot or human reviewers leave comments:
+- Run `/pr-address` to address review comments. It will loop until CI is green and all comments are resolved.
+- Do not merge without human approval.
+
+## Related skills
+
+| Skill | When to use |
+|---|---|
+| `/pr-test` | E2E testing with docker compose, agent-browser, API calls — use when you have a running workspace |
+| `/pr-review` | Review for correctness, security, code quality — use before requesting human review |
+| `/pr-address` | Address reviewer comments and loop until CI green — use after reviews come in |
+
+## Step 6: Post-creation
+
+After the PR is created and review is triggered:
+- Share the PR URL with the user
+- If waiting on the review bot, let the user know the expected wait time (~30 min)
+- Do not merge without human approval

+
+# Repository Setup
+
+This skill sets up a worktree-based development layout from a freshly cloned repo. It creates:
+- A **main** worktree (the primary checkout)
+- A **reviews** worktree (for PR reviews)
+- **N work branches** (branch1..branchN) for parallel development
+
+## Step 1: Identify the repo
+
+Determine the repo root and parent directory:
+
+```bash
+ROOT=$(git rev-parse --show-toplevel)
+REPO_NAME=$(basename "$ROOT")
+PARENT=$(dirname "$ROOT")
+```
+
+Detect if the repo is already inside a worktree layout by counting sibling worktrees (not just checking the directory name, which could be anything):
+
+```bash
+# Count worktrees that are siblings (live under $PARENT but aren't $ROOT itself)
+SIBLING_COUNT=$(git worktree list --porcelain 2>/dev/null | grep "^worktree " | grep -c "$PARENT/" || true)
+if [ "$SIBLING_COUNT" -gt 1 ]; then
+  echo "INFO: Existing worktree layout detected at $PARENT ($SIBLING_COUNT worktrees)"
+  # Use $ROOT as-is; skip renaming/restructuring
+else
+  echo "INFO: Fresh clone detected, proceeding with setup"
+fi
+```
+
+## Step 2: Ask the user questions
+
+Use AskUserQuestion to gather setup preferences:
+
+1. **How many parallel work branches do you need?** (Options: 4, 8, 16, or custom)
+   - These become `branch1` through `branchN`
+2. **Which branch should be the base?** (Options: origin/master, origin/dev, or custom)
+   - All work branches and reviews will start from this
+
+## Step 3: Fetch and set up branches
+
+```bash
+cd "$ROOT"
+git fetch origin
+
+# Create the reviews branch from base (skip if already exists)
+if git show-ref --verify --quiet refs/heads/reviews; then
+  echo "INFO: Branch 'reviews' already exists, skipping"
+else
+  git branch reviews <base-branch>
+fi
+
+# Create numbered work branches from base (skip if already exists)
+for i in $(seq 1 "$COUNT"); do
+  if git show-ref --verify --quiet "refs/heads/branch$i"; then
+    echo "INFO: Branch 'branch$i' already exists, skipping"
+  else
+    git branch "branch$i" <base-branch>
+  fi
+done
+```
+
+## Step 4: Create worktrees
+
+Create worktrees as siblings to the main checkout:
+
+```bash
+if [ -d "$PARENT/reviews" ]; then
+  echo "INFO: Worktree '$PARENT/reviews' already exists, skipping"
+else
+  git worktree add "$PARENT/reviews" reviews
+fi
+
+for i in $(seq 1 "$COUNT"); do
+  if [ -d "$PARENT/branch$i" ]; then
+    echo "INFO: Worktree '$PARENT/branch$i' already exists, skipping"
+  else
+    git worktree add "$PARENT/branch$i" "branch$i"
+  fi
+done
+```
+
+## Step 5: Set up environment files
+
+**Do NOT assume .env files exist.** For each worktree (including main if needed):
+
+1. Check if `.env` exists in the source worktree for each path
+2. If `.env` exists, copy it
+3. If only `.env.default` or `.env.example` exists, copy that as `.env`
+4. If neither exists, warn the user and list which env files are missing
+
+Env file locations to check (same as the `/worktree` skill — keep these in sync):
+- `autogpt_platform/.env`
+- `autogpt_platform/backend/.env`
+- `autogpt_platform/frontend/.env`
+
+> **Note:** This env copying logic intentionally mirrors the `/worktree` skill's approach. If you update the path list or fallback logic here, update `/worktree` as well.
+
+```bash
+SOURCE="$ROOT"
+WORKTREES="reviews"
+for i in $(seq 1 "$COUNT"); do WORKTREES="$WORKTREES branch$i"; done
+
+FOUND_ANY_ENV=0
+for wt in $WORKTREES; do
+  TARGET="$PARENT/$wt"
+  for envpath in autogpt_platform autogpt_platform/backend autogpt_platform/frontend; do
+    if [ -f "$SOURCE/$envpath/.env" ]; then
+      FOUND_ANY_ENV=1
+      cp "$SOURCE/$envpath/.env" "$TARGET/$envpath/.env"
+    elif [ -f "$SOURCE/$envpath/.env.default" ]; then
+      FOUND_ANY_ENV=1
+      cp "$SOURCE/$envpath/.env.default" "$TARGET/$envpath/.env"
+      echo "NOTE: $wt/$envpath/.env was created from .env.default — you may need to edit it"
+    elif [ -f "$SOURCE/$envpath/.env.example" ]; then
+      FOUND_ANY_ENV=1
+      cp "$SOURCE/$envpath/.env.example" "$TARGET/$envpath/.env"
+      echo "NOTE: $wt/$envpath/.env was created from .env.example — you may need to edit it"
+    else
+      echo "WARNING: No .env, .env.default, or .env.example found at $SOURCE/$envpath/"
+    fi
+  done
+done
+
+if [ "$FOUND_ANY_ENV" -eq 0 ]; then
+  echo "WARNING: No environment files or templates were found in the source worktree."
+  # Use AskUserQuestion to confirm: "Continue setup without env files?"
+  # If the user declines, stop here and let them set up .env files first.
+fi
+```
+
+## Step 6: Copy branchlet config
+
+Copy `.branchlet.json` from main to each worktree so branchlet can manage sub-worktrees:
+
+```bash
+if [ -f "$ROOT/.branchlet.json" ]; then
+  for wt in $WORKTREES; do
+    cp "$ROOT/.branchlet.json" "$PARENT/$wt/.branchlet.json"
+  done
+fi
+```
+
+## Step 7: Install dependencies
+
+Install deps in all worktrees. Run these sequentially per worktree:
+
+```bash
+for wt in $WORKTREES; do
+  TARGET="$PARENT/$wt"
+  echo "=== Installing deps for $wt ==="
+  (cd "$TARGET/autogpt_platform/autogpt_libs" && poetry install) &&
+  (cd "$TARGET/autogpt_platform/backend" && poetry install && poetry run prisma generate) &&
+  (cd "$TARGET/autogpt_platform/frontend" && pnpm install) &&
+  echo "=== Done: $wt ===" ||
+  echo "=== FAILED: $wt ==="
+done
+```
+
+This is slow. Run in background if possible and notify when complete.
+
+## Step 8: Verify and report
+
+After setup, verify and report to the user:
+
+```bash
+git worktree list
+```
+
+Summarize:
+- Number of worktrees created
+- Which env files were copied vs created from defaults vs missing
+- Any warnings or errors encountered
+
+## Final directory layout
+
+```
+parent/
+  main/              # Primary checkout (already exists)
+  reviews/           # PR review worktree
+  branch1/           # Work branch 1
+  branch2/           # Work branch 2
+  ...
+  branchN/           # Work branch N
+```

+# AutoGPT Platform
+
+This file provides guidance to coding agents when working with code in this repository.
+
+## Repository Overview
+
+AutoGPT Platform is a monorepo containing:
+
+- **Backend** (`backend`): Python FastAPI server with async support
+- **Frontend** (`frontend`): Next.js React application
+- **Shared Libraries** (`autogpt_libs`): Common Python utilities
+
+## Component Documentation
+
+- **Backend**: See @backend/AGENTS.md for backend-specific commands, architecture, and development tasks
+- **Frontend**: See @frontend/AGENTS.md for frontend-specific commands, architecture, and development patterns
+
+## Key Concepts
+
+1. **Agent Graphs**: Workflow definitions stored as JSON, executed by the backend
+2. **Blocks**: Reusable components in `backend/backend/blocks/` that perform specific tasks
+3. **Integrations**: OAuth and API connections stored per user
+4. **Store**: Marketplace for sharing agent templates
+5. **Virus Scanning**: ClamAV integration for file upload security
+
+### Environment Configuration
+
+#### Configuration Files
+
+- **Backend**: `backend/.env.default` (defaults) → `backend/.env` (user overrides)
+- **Frontend**: `frontend/.env.default` (defaults) → `frontend/.env` (user overrides)
+- **Platform**: `.env.default` (Supabase/shared defaults) → `.env` (user overrides)
+
+#### Docker Environment Loading Order
+
+1. `.env.default` files provide base configuration (tracked in git)
+2. `.env` files provide user-specific overrides (gitignored)
+3. Docker Compose `environment:` sections provide service-specific overrides
+4. Shell environment variables have highest precedence
+
+#### Key Points
+
+- All services use hardcoded defaults in docker-compose files (no `${VARIABLE}` substitutions)
+- The `env_file` directive loads variables INTO containers at runtime
+- Backend/Frontend services use YAML anchors for consistent configuration
+- Supabase services (`db/docker/docker-compose.yml`) follow the same pattern
+
+### Branching Strategy
+
+- **`dev`** is the main development branch. All PRs should target `dev`.
+- **`master`** is the production branch. Only used for production releases.
+
+### Creating Pull Requests
+
+- Create the PR against the `dev` branch of the repository.
+- **Split PRs by concern** — each PR should have a single clear purpose. For example, "usage tracking" and "credit charging" should be separate PRs even if related. Combining multiple concerns makes it harder for reviewers to understand what belongs to what.
+- Ensure the branch name is descriptive (e.g., `feature/add-new-block`)
+- Use conventional commit messages (see below)
+- **Structure the PR description with Why / What / How** — Why: the motivation (what problem it solves, what's broken/missing without it); What: high-level summary of changes; How: approach, key implementation details, or architecture decisions. Reviewers need all three to judge whether the approach fits the problem.
+- Fill out the .github/PULL_REQUEST_TEMPLATE.md template as the PR description
+- Always use `--body-file` to pass PR body — avoids shell interpretation of backticks and special characters:
+  ```bash
+  PR_BODY=$(mktemp)
+  cat > "$PR_BODY" << 'PREOF'
+  ## Summary
+  - use `backticks` freely here
+  PREOF
+  gh pr create --title "..." --body-file "$PR_BODY" --base dev
+  rm "$PR_BODY"
+  ```
+- Run the github pre-commit hooks to ensure code quality.
+
+### Test-Driven Development (TDD)
+
+When fixing a bug or adding a feature, follow a test-first approach:
+
+1. **Write a failing test first** — create a test that reproduces the bug or validates the new behavior, marked with `@pytest.mark.xfail` (backend) or `.fixme` (Playwright). Run it to confirm it fails for the right reason.
+2. **Implement the fix/feature** — write the minimal code to make the test pass.
+3. **Remove the xfail marker** — once the test passes, remove the `xfail`/`.fixme` annotation and run the full test suite to confirm nothing else broke.
+
+This ensures every change is covered by a test and that the test actually validates the intended behavior.
+
+### Reviewing/Revising Pull Requests
+
+Use `/pr-review` to review a PR or `/pr-address` to address comments.
+
+When fetching comments manually:
+- `gh api repos/Significant-Gravitas/AutoGPT/pulls/{N}/reviews --paginate` — top-level reviews
+- `gh api repos/Significant-Gravitas/AutoGPT/pulls/{N}/comments --paginate` — inline review comments (always paginate to avoid missing comments beyond page 1)
+- `gh api repos/Significant-Gravitas/AutoGPT/issues/{N}/comments` — PR conversation comments
+
+### Conventional Commits
+
+Use this format for commit messages and Pull Request titles:
+
+**Conventional Commit Types:**
+
+- `feat`: Introduces a new feature to the codebase
+- `fix`: Patches a bug in the codebase
+- `refactor`: Code change that neither fixes a bug nor adds a feature; also applies to removing features
+- `ci`: Changes to CI configuration
+- `docs`: Documentation-only changes
+- `dx`: Improvements to the developer experience
+
+**Recommended Base Scopes:**
+
+- `platform`: Changes affecting both frontend and backend
+- `frontend`
+- `backend`
+- `infra`
+- `blocks`: Modifications/additions of individual blocks
+
+**Subscope Examples:**
+
+- `backend/executor`
+- `backend/db`
+- `frontend/builder` (includes changes to the block UI component)
+- `infra/prod`
+
+Use these scopes and subscopes for clarity and consistency in commit messages.

+# Backend
+
+This file provides guidance to coding agents when working with the backend.
+
+## Essential Commands
+
+To run something with Python package dependencies you MUST use `poetry run ...`.
+
+```bash
+# Install dependencies
+poetry install
+
+# Run database migrations
+poetry run prisma migrate dev
+
+# Start all services (database, redis, rabbitmq, clamav)
+docker compose up -d
+
+# Run the backend as a whole
+poetry run app
+
+# Run tests
+poetry run test
+
+# Run specific test
+poetry run pytest path/to/test_file.py::test_function_name
+
+# Run block tests (tests that validate all blocks work correctly)
+poetry run pytest backend/blocks/test/test_block.py -xvs
+
+# Run tests for a specific block (e.g., GetCurrentTimeBlock)
+poetry run pytest 'backend/blocks/test/test_block.py::test_available_blocks[GetCurrentTimeBlock]' -xvs
+
+# Lint and format
+# prefer format if you want to just "fix" it and only get the errors that can't be autofixed
+poetry run format  # Black + isort
+poetry run lint    # ruff
+```
+
+More details can be found in @TESTING.md
+
+### Creating/Updating Snapshots
+
+When you first write a test or when the expected output changes:
+
+```bash
+poetry run pytest path/to/test.py --snapshot-update
+```
+
+⚠️ **Important**: Always review snapshot changes before committing! Use `git diff` to verify the changes are expected.
+
+## Architecture
+
+- **API Layer**: FastAPI with REST and WebSocket endpoints
+- **Database**: PostgreSQL with Prisma ORM, includes pgvector for embeddings
+- **Queue System**: RabbitMQ for async task processing
+- **Execution Engine**: Separate executor service processes agent workflows
+- **Authentication**: JWT-based with Supabase integration
+- **Security**: Cache protection middleware prevents sensitive data caching in browsers/proxies
+
+## Code Style
+
+- **Top-level imports only** — no local/inner imports (lazy imports only for heavy optional deps like `openpyxl`)
+- **Absolute imports** — use `from backend.module import ...` for cross-package imports. Single-dot relative (`from .sibling import ...`) is acceptable for sibling modules within the same package (e.g., blocks). Avoid double-dot relative imports (`from ..parent import ...`) — use the absolute path instead
+- **No duck typing** — no `hasattr`/`getattr`/`isinstance` for type dispatch; use typed interfaces/unions/protocols
+- **Pydantic models** over dataclass/namedtuple/dict for structured data
+- **No linter suppressors** — no `# type: ignore`, `# noqa`, `# pyright: ignore`; fix the type/code
+- **List comprehensions** over manual loop-and-append
+- **Early return** — guard clauses first, avoid deep nesting
+- **f-strings vs printf syntax in log statements** — Use `%s` for deferred interpolation in `debug` statements, f-strings elsewhere for readability: `logger.debug("Processing %s items", count)`, `logger.info(f"Processing {count} items")`
+- **Sanitize error paths** — `os.path.basename()` in error messages to avoid leaking directory structure
+- **TOCTOU awareness** — avoid check-then-act patterns for file access and credit charging
+- **`Security()` vs `Depends()`** — use `Security()` for auth deps to get proper OpenAPI security spec
+- **Redis pipelines** — `transaction=True` for atomicity on multi-step operations
+- **`max(0, value)` guards** — for computed values that should never be negative
+- **SSE protocol** — `data:` lines for frontend-parsed events (must match Zod schema), `: comment` lines for heartbeats/status
+- **File length** — keep files under ~300 lines; if a file grows beyond this, split by responsibility (e.g. extract helpers, models, or a sub-module into a new file). Never keep appending to a long file.
+- **Function length** — keep functions under ~40 lines; extract named helpers when a function grows longer. Long functions are a sign of mixed concerns, not complexity.
+- **Top-down ordering** — define the main/public function or class first, then the helpers it uses below. A reader should encounter high-level logic before implementation details.
+
+## Testing Approach
+
+- Uses pytest with snapshot testing for API responses
+- Test files are colocated with source files (`*_test.py`)
+- Mock at boundaries — mock where the symbol is **used**, not where it's **defined**
+- After refactoring, update mock targets to match new module paths
+- Use `AsyncMock` for async functions (`from unittest.mock import AsyncMock`)
+
+### Test-Driven Development (TDD)
+
+When fixing a bug or adding a feature, write the test **before** the implementation:
+
+```python
+# 1. Write a failing test marked xfail
+@pytest.mark.xfail(reason="Bug #1234: widget crashes on empty input")
+def test_widget_handles_empty_input():
+    result = widget.process("")
+    assert result == Widget.EMPTY_RESULT
+
+# 2. Run it — confirm it fails (XFAIL)
+# poetry run pytest path/to/test.py::test_widget_handles_empty_input -xvs
+
+# 3. Implement the fix
+
+# 4. Remove xfail, run again — confirm it passes
+def test_widget_handles_empty_input():
+    result = widget.process("")
+    assert result == Widget.EMPTY_RESULT
+```
+
+This catches regressions and proves the fix actually works. **Every bug fix should include a test that would have caught it.**
+
+## Database Schema
+
+Key models (defined in `schema.prisma`):
+
+- `User`: Authentication and profile data
+- `AgentGraph`: Workflow definitions with version control
+- `AgentGraphExecution`: Execution history and results
+- `AgentNode`: Individual nodes in a workflow
+- `StoreListing`: Marketplace listings for sharing agents
+
+## Environment Configuration
+
+- **Backend**: `.env.default` (defaults) → `.env` (user overrides)
+
+## Common Development Tasks
+
+### Adding a new block
+
+Follow the comprehensive [Block SDK Guide](@../../docs/platform/block-sdk-guide.md) which covers:
+
+- Provider configuration with `ProviderBuilder`
+- Block schema definition
+- Authentication (API keys, OAuth, webhooks)
+- Testing and validation
+- File organization
+
+Quick steps:
+
+1. Create new file in `backend/blocks/`
+2. Configure provider using `ProviderBuilder` in `_config.py`
+3. Inherit from `Block` base class
+4. Define input/output schemas using `BlockSchema`
+5. Implement async `run` method
+6. Generate unique block ID using `uuid.uuid4()`
+7. Test with `poetry run pytest backend/blocks/test/test_block.py`
+
+Note: when making many new blocks analyze the interfaces for each of these blocks and picture if they would go well together in a graph-based editor or would they struggle to connect productively?
+ex: do the inputs and outputs tie well together?
+
+If you get any pushback or hit complex block conditions check the new_blocks guide in the docs.
+
+#### Handling files in blocks with `store_media_file()`
+
+When blocks need to work with files (images, videos, documents), use `store_media_file()` from `backend.util.file`. The `return_format` parameter determines what you get back:
+
+| Format | Use When | Returns |
+|--------|----------|---------|
+| `"for_local_processing"` | Processing with local tools (ffmpeg, MoviePy, PIL) | Local file path (e.g., `"image.png"`) |
+| `"for_external_api"` | Sending content to external APIs (Replicate, OpenAI) | Data URI (e.g., `"data:image/png;base64,..."`) |
+| `"for_block_output"` | Returning output from your block | Smart: `workspace://` in CoPilot, data URI in graphs |
+
+**Examples:**
+
+```python
+# INPUT: Need to process file locally with ffmpeg
+local_path = await store_media_file(
+    file=input_data.video,
+    execution_context=execution_context,
+    return_format="for_local_processing",
+)
+# local_path = "video.mp4" - use with Path/ffmpeg/etc
+
+# INPUT: Need to send to external API like Replicate
+image_b64 = await store_media_file(
+    file=input_data.image,
+    execution_context=execution_context,
+    return_format="for_external_api",
+)
+# image_b64 = "data:image/png;base64,iVBORw0..." - send to API
+
+# OUTPUT: Returning result from block
+result_url = await store_media_file(
+    file=generated_image_url,
+    execution_context=execution_context,
+    return_format="for_block_output",
+)
+yield "image_url", result_url
+# In CoPilot: result_url = "workspace://abc123"
+# In graphs:  result_url = "data:image/png;base64,..."
+```
+
+**Key points:**
+
+- `for_block_output` is the ONLY format that auto-adapts to execution context
+- Always use `for_block_output` for block outputs unless you have a specific reason not to
+- Never hardcode workspace checks - let `for_block_output` handle it
+
+### Modifying the API
+
+1. Update route in `backend/api/features/`
+2. Add/update Pydantic models in same directory
+3. Write tests alongside the route file
+4. Run `poetry run test` to verify
+
+## Workspace & Media Files
+
+**Read [Workspace & Media Architecture](../../docs/platform/workspace-media-architecture.md) when:**
+- Working on CoPilot file upload/download features
+- Building blocks that handle `MediaFileType` inputs/outputs
+- Modifying `WorkspaceManager` or `store_media_file()`
+- Debugging file persistence or virus scanning issues
+
+Covers: `WorkspaceManager` (persistent storage with session scoping), `store_media_file()` (media normalization pipeline), and responsibility boundaries for virus scanning and persistence.
+
+## Security Implementation
+
+### Cache Protection Middleware
+
+- Located in `backend/api/middleware/security.py`
+- Default behavior: Disables caching for ALL endpoints with `Cache-Control: no-store, no-cache, must-revalidate, private`
+- Uses an allow list approach - only explicitly permitted paths can be cached
+- Cacheable paths include: static assets (`static/*`, `_next/static/*`), health checks, public store pages, documentation
+- Prevents sensitive data (auth tokens, API keys, user data) from being cached by browsers/proxies
+- To allow caching for a new endpoint, add it to `CACHEABLE_PATHS` in the middleware
+- Applied to both main API server and external API applications

-# CLAUDE.md - Backend
-
-This file provides guidance to Claude Code when working with the backend.
-
-## Essential Commands
-
-To run something with Python package dependencies you MUST use `poetry run ...`.
-
-```bash
-# Install dependencies
-poetry install
-
-# Run database migrations
-poetry run prisma migrate dev
-
-# Start all services (database, redis, rabbitmq, clamav)
-docker compose up -d
-
-# Run the backend as a whole
-poetry run app
-
-# Run tests
-poetry run test
-
-# Run specific test
-poetry run pytest path/to/test_file.py::test_function_name
-
-# Run block tests (tests that validate all blocks work correctly)
-poetry run pytest backend/blocks/test/test_block.py -xvs
-
-# Run tests for a specific block (e.g., GetCurrentTimeBlock)
-poetry run pytest 'backend/blocks/test/test_block.py::test_available_blocks[GetCurrentTimeBlock]' -xvs
-
-# Lint and format
-# prefer format if you want to just "fix" it and only get the errors that can't be autofixed
-poetry run format  # Black + isort
-poetry run lint    # ruff
-```
-
-More details can be found in @TESTING.md
-
-### Creating/Updating Snapshots
-
-When you first write a test or when the expected output changes:
-
-```bash
-poetry run pytest path/to/test.py --snapshot-update
-```
-
-⚠️ **Important**: Always review snapshot changes before committing! Use `git diff` to verify the changes are expected.

+Before starting the workflow below, check whether the user's goal is

+1. Call `find_block` with a query targeting the ambiguous dimension to

+2. Ask the user **one concrete question** grounded in the discovered

+Validates the fix for the Anthropic API error:

+    cannot be modified. These blocks must remain as they were in the
+    original response."
+
+The API requires that thinking blocks in the LAST assistant message are
+preserved value-identical. Older assistant messages may have thinking blocks
+stripped entirely. This test suite covers:
+
+  1. _flatten_assistant_content — strips thinking from older messages
+  2. compact_transcript — preserves last assistant's thinking blocks
+  3. response_adapter — handles ThinkingBlock without error
+  4. _format_sdk_content_blocks — preserves redacted_thinking blocks

+1. `_resolve_discriminated_credentials` correctly populates discriminator_values
+   for URL-based (host-scoped) and provider-based (api_key) credential fields.
+2. `find_matching_credential` correctly matches credentials for all types:
+   APIKeyCredentials, OAuth2Credentials, UserPasswordCredentials, and
+   HostScopedCredentials.
+3. The full `resolve_block_credentials` flow correctly resolves matching
+   credentials or reports them as missing for each credential type.
+4. `RunBlockTool._execute` end-to-end tests return correct response types.
