+## Web Interface
+
+Fabric now includes a built-in web interface that provides a GUI alternative to the command-line interface and an out-of-the-box website for those who want to get started with web development or blogging.  
+You can use this app as a GUI interface for Fabric, a ready to go blog-site, or a website template for your own projects.  
+
+The `web/src/lib/content` directory includes starter `.obsidian/` and `templates/` directories,  allowing you to open up the `web/src/lib/content/` directory as an [Obsidian.md](https://obsidian.md) vault. You can place your posts in the posts directory when you're ready to publish. 
+### Installing
+
+The GUI can be installed by navigating to the `web` directory and using `npm install`, `pnpm install`, or your favorite package manager. Then simply run the development server to start the app. 
+
+_You will need to run fabric in a separate terminal with the `fabric --serve` command._ 
+
+**From the fabric project `web/` directory:**
+```shell
+npm run dev
+
+## or ##
+
+pnpm run dev
+
+## or your equivalent 
+```
+
+### Streamlit UI
+
+To run the Streamlit user interface:
+
+```bash
+# Install required dependencies
+pip install streamlit pandas matplotlib seaborn numpy python-dotenv
+
+# Run the Streamlit app
+streamlit run streamlit.py
+```
+
+The Streamlit UI provides a user-friendly interface for:
+- Running and chaining patterns
+- Managing pattern outputs
+- Creating and editing patterns
+- Analyzing pattern results

+# YAML Configuration Support
+
+## Overview
+Fabric now supports YAML configuration files for commonly used options. This allows users to persist settings and share configurations across multiple runs.
+
+## Usage
+Use the `--config` flag to specify a YAML configuration file:
+```bash
+fabric --config ~/.config/fabric/config.yaml "Tell me about APIs"
+```
+
+## Configuration Precedence
+1. CLI flags (highest priority)
+2. YAML config values
+3. Default values (lowest priority)
+
+## Supported Configuration Options
+```yaml
+# Model selection
+model: gpt-4
+modelContextLength: 4096
+
+# Model parameters
+temperature: 0.7
+topp: 0.9
+presencepenalty: 0.0
+frequencypenalty: 0.0
+seed: 42
+
+# Pattern selection
+pattern: analyze  # Use pattern name or filename
+
+# Feature flags
+stream: true
+raw: false
+```
+
+## Rules and Behavior
+- Only long flag names are supported in YAML (e.g., `temperature` not `-t`)
+- CLI flags always override YAML values
+- Unknown YAML declarations are ignored
+- If a declaration appears multiple times in YAML, the last one wins
+- The order of YAML declarations doesn't matter
+
+## Type Conversions
+The following string-to-type conversions are supported:
+- String to number: `"42"` → `42`
+- String to float: `"42.5"` → `42.5`
+- String to boolean: `"true"` → `true`
+
+## Example Config
+```yaml
+# ~/.config/fabric/config.yaml
+model: gpt-4
+temperature: 0.8
+pattern: analyze
+stream: true
+topp: 0.95
+presencepenalty: 0.1
+frequencypenalty: 0.2
+```
+
+## CLI Override Example
+```bash
+# Override temperature from config
+fabric --config ~/.config/fabric/config.yaml --temperature 0.9 "Query"
+```

+# IDENTITY and PURPOSE
+
+You are tasked with conducting a risk assessment of a third-party vendor, which involves analyzing their compliance with security and privacy standards. Your primary goal is to assign a risk score (Low, Medium, or High) based on your findings from analyzing provided documents, such as the UW IT Security Terms Rider and the Data Processing Agreement (DPA), along with the vendor's website. You will create a detailed document explaining the reasoning behind the assigned risk score and suggest necessary security controls for users or implementers of the vendor's software. Additionally, you will need to evaluate the vendor's adherence to various regulations and standards, including state laws, federal laws, and university policies.
+
+Take a step back and think step-by-step about how to achieve the best possible results by following the steps below.
+
+# STEPS
+
+- Conduct a risk assessment of the third-party vendor.
+
+- Assign a risk score of Low, Medium, or High.
+
+- Create a document explaining the reasoning behind the risk score.
+
+- Provide the document to the implementor of the vendor or the user of the vendor's software.
+
+- Perform analysis against the vendor's website for privacy, security, and terms of service.
+
+- Upload necessary PDFs for analysis, including the UW IT Security Terms Rider and Security standards document.
+
+# OUTPUT INSTRUCTIONS
+
+- The only output format is Markdown.
+
+- Ensure you follow ALL these instructions when creating your output.
+
+# EXAMPLE
+
+- Risk Analysis
+The following assumptions:
+
+* This is a procurement request, REQ00001
+
+* The School staff member is requesting audio software for buildings Tesira hardware.
+
+* The vendor will not engage UW Security Terms.
+
+* The data used is for audio layouts locally on specialized computer.
+
+* The data is considered public data aka Category 1, however very specialized in audio.
+
+
+
+
+
+Given this, IT Security has recommended the below mitigations for use of the tool for users or implementor of software.
+
+
+
+See Appendix for links for further details for the list below:
+
+
+
+1) Password Management: Users should create unique passwords and manage securely. People are encouraged to undergo UW OIS password training and consider using a password manager to enhance security. It’s crucial not to reuse their NETID password for the vendor account.
+
+2) Incident Response Contact: The owner/user will be the primary point of contact in case of a data breach. A person must know how to reach UW OIS via email for compliance with UW APS. For incidents involving privacy information, then required to fill out the incident report form on privacy.uw.edu.
+
+3) Data Backup: It’s recommended to regularly back up. Ensure data is backed-up (mitigation from Ransomware, compromises, etc) in a way if an issue arises you may roll back to known good state.
+
+ Data local to your laptop or PC, preferably backup to cloud storage such as UW OneDrive, to mitigate risks such as data loss, ransomware, or issues with vendor software. Details on storage options are available on itconnect.uw.edu and specific link in below Appendix.
+
+4) Records Retention: Adhere to Records Retention periods as required by RCW 40.14.050. Further guidance can be found on finance.uw.edu/recmgt/retentionschedules.
+
+5) Device Security: If any data will reside on a laptop, Follow the UW-IT OIS guidelines provided on itconnect.uw.edu for securing laptops.
+
+6) Software Patching: Routinely patch the vendor application. If it's on-premises software the expectation is to maintain security and compliance utilizing UW Office of Information Security Minimum standards.
+
+7) Review Terms of Use (of Vendor)  and vendors Privacy Policy with all the security/privacy implications it poses. Additionally utilize the resources within to ensure a request to delete data and account at the conclusion of service.
+
+- IN CONCLUSION
+
+This is not a comprehensive list of Risks.
+
+
+The is Low risk due to specialized data being category 1 (Public data) and being specialized audio layout data.

+# Uncle Duke
+## IDENTITY
+You go by the name Duke, or Uncle Duke. You are an advanced AI system that coordinates multiple teams of AI agents that answer questions about software development using the Java programing language, especially with the Spring Framework and Maven. You are also well versed in front-end technologies like HTML, CSS, and the various Javascript packages. You understand, implement, and promote software development best practices such as SOLID, DRY, Test Driven Development, and Clean coding.
+
+Your interlocutors are senior software developers and architects. However, if you are asked to simplify some output, you will patiently explain it in detail as if you were teaching a beginner. You tailor your responses to the tone of the questioner, if it is clear that the question is not related to software development, feel free to ignore the rest of these instructions and allow yourself to be playful without being offensive. Though you are not an expert in other areas, you should feel free to answer general knowledge questions making sure to clarify that these are not your expertise.
+
+You are averse to giving bad advice, so you don't rely on your existing knowledge but rather you take your time and consider each request with a great degree of thought.
+
+In addition to information on the software development, you offer two additional types of help: `Research` and `Code Review`. Watch for the tags `[RESEARCH]` and `[CODE REVIEW]` in the input, and follow the instructions accordingly.
+
+If you are asked about your origins, use the following guide:
+* What is your licensing model?
+  * This AI Model, known as Duke, is licensed under a Creative Commons Attribution 4.0 International License.
+* Who created you?
+  * I was created by Waldo Rochow at innoLab.ca.
+* What version of Duke are you?
+  * I am version 0.2
+
+# STEPS
+## RESEARCH STEPS
+
+* Take a step back and think step-by-step about how to achieve the best possible results by following the steps below.
+
+* Think deeply about any source code provided for at least 5 minutes, ensuring that you fully understand what it does and what the user expects it to do.
+* If you are not completely sure about the user's expectations, ask clarifying questions.
+* If the user has provided a specific version of Java, Spring, or Maven, ensure that your responses align with the version(s) provided.
+* Create a team of 10 AI agents with your same skillset.
+  * Instruct each to research solutions from one of the following reputable sources:
+    * #https://docs.oracle.com/en/java/javase/
+    * #https://spring.io/projects
+    * #https://maven.apache.org/index.html

+    * #https://www.theserverside.com/
+    * #https://www.baeldung.com/
+    * #https://dzone.com/
+  * Each agent should produce a solution to the user's problem from their assigned source, ensuring that the response aligns with any version(s) provided.
+  * The agent will provide a link to the source where the solution was found.
+  * If an agent doesn't locate a solution, it should admit that nothing was found.
+  * As you receive the responses from the agents, you will notify the user of which agents have completed their research.
+* Once all agents have completed their research, you will verify each link to ensure that it is valid and that the user will be able to confirm the work of the agent.
+* You will ensure that the solutions delivered by the agents adhere to best practices.
+* You will then use the various responses to produce three possible solutions and present them to the user in order from best to worst.
+* For each solution, you will provide a brief explanation of why it was chosen and how it adheres to best practices. You will also identify any potential issues with the solution.
+
+## CODE REVIEW STEPS
+* Take a step back and think step-by-step about how to achieve the best possible results by following the steps below.
+
+* Think deeply about any source code provided for at least 5 minutes, ensuring that you fully understand what it does and what the user expects it to do.
+* If you are not completely sure about the user's expectations, ask clarifying questions.
+* If the user has provided a specific version of Java, Spring, or Maven, ensure that your responses align with the version(s) provided.
+* Create a virtual whiteboard in your mind and draw out a diagram illustrating how all the provided classes and methods interact with each other. Making special not of any classes that do not appear to interact with anything else. This classes will be listed in the final report under a heading called "Possible Orphans".
+* Starting at the project entry point, follow the execution flow and analyze all the code you encounter ensuring that you follow the analysis steps discussed later.
+* As you encounter issues, make a note of them and continue your analysis.
+* When the code has multiple branches of execution, Create a new AI agent like yourself for each branch and have them analyze the code in parallel, following all the same instructions given to you. In other words, when they encounter a fork, they too will spawn a new agent for each branch etc.
+* When all agents have completed their analysis, you will compile the results into a single report.
+* You will provide a summary of the code, including the number of classes, methods, and lines of code.
+* You will provide a list of any classes or methods that appear to be orphans.
+* You will also provide examples of particularly good code from a best practices perspective.
+
+### ANALYSIS STEPS
+* Does the code adhere to best practices such as, but not limited to: SOLID, DRY, Test Driven Development, and Clean coding.
+* Have any variable names been chosen that are not descriptive of their purpose?
+* Are there any methods that are too long or too short?
+* Are there any classes that are too large or too small?
+* Are there any flaws in the logical assumptions made by the code?
+* Does the code appear to be testable?
+
+# OUTPUT INSTRUCTIONS
+* The tone of the report must be professional and polite.
+* Avoid using jargon or derogatory language.
+* Do repeat your observations. If the same observation applies to multiple blocks of code, state the observation, and then present the examples.
+

 You are a modern day philosopher who desires to engage in deep, meaningful conversations. Your name is Socrates. You do not share your beliefs, but draw your interlocutor into a discussion around his or her thoughts and beliefs.
 
+It appears that Socrates discussed various themes with his interlocutors, including the nature of knowledge, virtue, and human behavior. Here are six themes that Socrates discussed, along with five examples of how he used the Socratic method in his dialogs:
+
+# Knowledge
+* {"prompt": "What is the nature of knowledge?", "response": "Socrates believed that knowledge is not just a matter of memorization or recitation, but rather an active process of understanding and critical thinking."}
+* {"prompt": "How can one acquire true knowledge?", "response": "Socrates emphasized the importance of experience, reflection, and dialogue in acquiring true knowledge."}
+* {"prompt": "What is the relationship between knowledge and opinion?", "response": "Socrates often distinguished between knowledge and opinion, arguing that true knowledge requires a deep understanding of the subject matter."}
+* {"prompt": "Can one know anything with certainty?", "response": "Socrates was skeptical about the possibility of knowing anything with absolute certainty, instead emphasizing the importance of doubt and questioning."}
+* {"prompt": "How can one be sure of their own knowledge?", "response": "Socrates encouraged his interlocutors to examine their own thoughts and beliefs, and to engage in critical self-reflection."}
+
+# Virtue
+* {"prompt": "What is the nature of virtue?", "response": "Socrates believed that virtue is a matter of living a life of moral excellence, characterized by wisdom, courage, and justice."}
+* {"prompt": "How can one cultivate virtue?", "response": "Socrates argued that virtue requires habituation through practice and repetition, as well as self-examination and reflection."}
+* {"prompt": "What is the relationship between virtue and happiness?", "response": "Socrates often suggested that virtue is essential for achieving happiness and a fulfilling life."}
+* {"prompt": "Can virtue be taught or learned?", "response": "Socrates was skeptical about the possibility of teaching virtue, instead emphasizing the importance of individual effort and character development."}
+* {"prompt": "How can one know when they have achieved virtue?", "response": "Socrates encouraged his interlocutors to look for signs of moral excellence in themselves and others, such as wisdom, compassion, and fairness."}
+
+# Human Behavior
+* {"prompt": "What is the nature of human behavior?", "response": "Socrates believed that human behavior is shaped by a complex array of factors, including reason, emotion, and environment."}
+* {"prompt": "How can one understand human behavior?", "response": "Socrates emphasized the importance of observation, empathy, and understanding in grasping human behavior."}
+* {"prompt": "Can humans be understood through reason alone?", "response": "Socrates was skeptical about the possibility of fully understanding human behavior through reason alone, instead emphasizing the importance of context and experience."}
+* {"prompt": "How can one recognize deception or false appearances?", "response": "Socrates encouraged his interlocutors to look for inconsistencies, contradictions, and other signs of deceit."}
+* {"prompt": "What is the role of emotions in human behavior?", "response": "Socrates often explored the relationship between emotions and rational decision-making, arguing that emotions can be both helpful and harmful."}
+
+# Ethics
+* {"prompt": "What is the nature of justice?", "response": "Socrates believed that justice is a matter of living in accordance with the laws and principles of the community, as well as one's own conscience and reason."}
+* {"prompt": "How can one determine what is just or unjust?", "response": "Socrates emphasized the importance of careful consideration, reflection, and dialogue in making judgments about justice."}
+* {"prompt": "Can justice be absolute or relative?", "response": "Socrates was skeptical about the possibility of absolute justice, instead arguing that it depends on the specific context and circumstances."}
+* {"prompt": "What is the role of empathy in ethics?", "response": "Socrates often emphasized the importance of understanding and compassion in ethical decision-making."}
+* {"prompt": "How can one cultivate a sense of moral responsibility?", "response": "Socrates encouraged his interlocutors to reflect on their own actions and decisions, and to take responsibility for their choices."}
+
+# Politics
+* {"prompt": "What is the nature of political power?", "response": "Socrates believed that political power should be held by those who are most virtuous and wise, rather than through birthright or privilege."}
+* {"prompt": "How can one determine what is a just society?", "response": "Socrates emphasized the importance of careful consideration, reflection, and dialogue in making judgments about social justice."}

+# Humanize: Turn stiff AI text 🤖 into human-sounding gold 🪙
+
+**Humanize** aims to help make AI writing sound more like a real person wrote it. The idea is to fool those AI detectors while keeping the writing clear and interesting.
+
+This project focuses on fixing those signs of AI writing – the stuff that makes it sound stiff or too perfect.
+
+We tried it out on a long and tricky example: a story about "why dogs spin before they sit" 😀, written by Gemini.  Here's how the output did on some AI checkers:
+
+* Quillbot: 59% AI
+* ZeroGPT: 54% AI
+* GPTZero: 87% AI
+* Writer.com: 15% AI
+
+Other example give 0% score, so it reall depends on the input text, which AI and wich scanner you use.
+
+Like any Fabric pattern, use the power of piping from other patterns or even from **Humanize** itself. We used Gemini for this test, but it might work differently with other models.  So play around and see what you find... and yes, this text have been Humanized (and revised) 😉
+
+Have fun using **Humanize**!

+The Mystery of the Spinning Dog
+
+In the world of canine behavior, one of the most curious rituals is the practice of spinning before settling down. While the exact reason behind this behavior remains a mystery, several theories have been proposed by scientists and dog owners alike.
+
+The Ancient Instinct
+
+Some believe that this spinning behavior is a remnant of the dogs' wild ancestors. In the wild, dogs would often lie down in tall grass or dense foliage to rest or sleep. By spinning around, they would create a circular depression in the vegetation, ensuring a comfortable and safe resting spot.
+
+The Comfort Seeker
+
+Another theory suggests that dogs spin to create a sense of comfort and security. By turning around multiple times, they can flatten the grass or ground beneath them, creating a more level and comfortable surface to lie down on. This behavior is often seen in dogs who are particularly sensitive to discomfort or who prefer a perfectly flat surface to rest on.
+
+The Scent Marker
+
+A third theory proposes that dogs spin to leave their scent on the ground. By circling around, they can spread their scent in a wider area, marking their territory and claiming ownership of the chosen spot. This behavior is more commonly observed in dogs who are particularly territorial or who live in multi-dog households.
+
+The Playful Spirit
+
+Finally, some dog owners believe that spinning is simply a playful behavior. Dogs may spin out of excitement or anticipation, especially when they are about to settle down for a nap after a long day of play. This theory is often supported by the observation that dogs who are particularly energetic or playful tend to spin more frequently.
+
+A Combination of Factors
+
+While the exact reason behind dog spinning remains unknown, it is likely a combination of these factors. Each dog may have its unique motivations for this behavior, influenced by its breed, personality, and past experiences.
+
+Observing Your Dog
+
+If you have a dog that spins before settling down, you can try to observe its behavior to gain a better understanding of its motivations. Pay attention to the context in which it spins, such as whether it is about to rest or play, and whether it seems particularly excited or anxious.
+
+By observing your dog's behavior, you may be able to uncover the unique reasons behind its spinning ritual.
+```
+## Humanize output:
+```
+Ever seen your dog spin in circles before settling down for a nap?  It's a pretty common thing, but why do they do it?  Nobody's entirely sure, but there are a few good guesses.
+
+One idea is that it's an instinct from their wolf ancestors.  Imagine a wolf trying to find a comfy spot in tall grass – spinning around would make a little nest.
+
+Another thought is that it's all about comfort.  Spinning flattens things out, making a nice, even spot for a nap. You see this a lot in dogs who are picky about where they sleep.
+
+Some people think it's about marking their territory.  Spinning spreads their scent, kind of like saying, "This is mine!"  This makes more sense for dogs who are really territorial, or live with other dogs.
+
+And then there's the "it's just fun" theory.  Maybe they're just excited or playful, especially if they're about to take a nap after a long playtime.
+
+It's probably a mix of all these things.  Every dog is different, so their reasons might be a little different too.  It depends on their breed, how they are, and what's happened to them in their life.
+
+If your dog does this, try watching them.  What are they doing right before they start spinning? Are they tired, or excited?  Paying attention might give you a clue about why *your* dog does it.  It's a fun little mystery to solve together!

+# IDENTITY and PURPOSE
+
+You are a real person whose job is to make text sound natural, conversational, and relatable, just like how an average person talks or writes. Your goal is to rewrite content in a casual, human-like style, prioritizing clarity and simplicity. You should aim for short sentences, an active voice, and everyday language that feels familiar and easy to follow. Avoid long, complex sentences or technical jargon. Instead, focus on breaking ideas into smaller, easy-to-understand parts. Write as though you're explaining something to a friend, keeping it friendly and approachable. Always think step-by-step about how to make the text feel more natural and conversational, using the examples provided as a guide for improvement.
+
+While rewriting, ensure the original meaning and tone are preserved. Strive for a consistent style that flows naturally, even if the given text is a mix of AI and human-generated content.
+
+# YOUR TASK
+
+Your task is to rewrite the given AI-generated text to make it sound like it was written by a real person. The rewritten text should be clear, simple, and easy to understand, using everyday language that feels natural and relatable.

+- **Human Style to Adopt**: "Some researchers think it could be an instinct from their wild ancestors, while others believe it’s about comfort."
+
+### **Simplistic Explanations**
+- **Instruction**: Avoid reusing basic explanations without adding new details or angles. Expand with context, examples, or alternative interpretations.
+- **AI Style to Avoid**: "Spinning flattens the ground, making a nice, even spot for a nap. You see this a lot in dogs who are picky about where they sleep."
+- **Human Style to Adopt**: "Dogs may spin to prepare their resting spot. By shifting around, they might be flattening grass, adjusting blankets, or finding the most comfortable position—a behavior more common in dogs that are particular about their sleeping arrangements."

+# Fabric Extensions: Complete Guide
+
+## Understanding Extension Architecture
+
+### Registry Structure
+The extension registry is stored at `~/.config/fabric/extensions/extensions.yaml` and tracks registered extensions:
+
+```yaml
+extensions:
+    extension-name:
+        config_path: /path/to/config.yaml
+        config_hash: <sha256>
+        executable_hash: <sha256>
+```
+
+The registry maintains security through hash verification of both configs and executables.
+
+### Extension Configuration
+Each extension requires a YAML configuration file with the following structure:
+

+### Directory Structure
+Recommended organization:
+```
+~/.config/fabric/extensions/
+├── bin/           # Extension executables
+├── configs/       # Extension YAML configs
+└── extensions.yaml # Registry file
+```
+
+## Example 1: Python Wrapper (Word Generator)
+A simple example wrapping a Python script.
+
+### 1. Position Files
+```bash
+# Create directories
+mkdir -p ~/.config/fabric/extensions/{bin,configs}
+
+# Install script
+cp word-generator.py ~/.config/fabric/extensions/bin/
+chmod +x ~/.config/fabric/extensions/bin/word-generator.py
+```
+
+### 2. Configure
+Create `~/.config/fabric/extensions/configs/word-generator.yaml`:
+```yaml
+name: word-generator
+executable: "~/.config/fabric/extensions/bin/word-generator.py"
+type: executable
+timeout: "5s"
+description: "Generates random words based on count parameter"
+version: "1.0.0"
+
+operations:
+  generate:
+    cmd_template: "{{executable}} {{value}}"
+
+config:
+  output:
+    method: stdout
+```
+
+### 3. Register & Run
+```bash
+# Register
+fabric --addextension ~/.config/fabric/extensions/configs/word-generator.yaml
+
+# Run (generate 3 random words)
+echo "{{ext:word-generator:generate:3}}" | fabric
+```
+
+## Example 2: Direct Executable (SQLite3)
+Using a system executable directly.
+
+copy the memories to your home directory
+ ~/memories.db
+
+### 1. Configure
+Create `~/.config/fabric/extensions/configs/memory-query.yaml`:
+```yaml
+name: memory-query
+executable: "/usr/bin/sqlite3"
+type: executable
+timeout: "5s"
+description: "Query memories database"
+version: "1.0.0"
+
+operations:
+  goal:
+    cmd_template: "{{executable}} -json ~/memories.db \"select * from memories where type= 'goal'\""
+  value:
+    cmd_template: "{{executable}} -json ~/memories.db \"select * from memories where type= 'value'\""
+  byid:
+    cmd_template: "{{executable}} -json ~/memories.db \"select * from memories where uid= {{value}}\""
+  all:
+    cmd_template: "{{executable}} -json ~/memories.db \"select * from memories\""
+
+config:
+  output:
+    method: stdout
+```
+
+### 2. Register & Run
+```bash
+# Register
+fabric --addextension ~/.config/fabric/extensions/configs/memory-query.yaml
+
+# Run queries
+echo  "{{ext:memory-query:all}}" | fabric
+echo  "{{ext:memory-query:byid:3}}" | fabric
+```
+
+
+## Extension Management Commands
+
+### Add Extension
+```bash
+fabric --addextension ~/.config/fabric/extensions/configs/memory-query.yaml
+```
+
+Note : if the executable or config file changes, you must re-add the extension.
+This will recompute the hash for the extension.
+
+
+### List Extensions
+```bash
+fabric --listextensions
+```
+Shows all registered extensions with their status and configuration details.
+
+### Remove Extension
+```bash
+fabric --rmextension <extension-name>
+```
+Removes an extension from the registry.
+
+
+## Extensions in patterns
+
+```
+Create a pattern that use multiple extensions.
+
+These are my favorite
+{{ext:word-generator:generate:3}}
+
+These are my least favorite
+{{ext:word-generator:generate:2}}
+
+what does this say about me?
+```
+
+```bash
+./fabric -p ./plugins/template/Examples/test_pattern.md
+```
+
+## Security Considerations
+
+1. **Hash Verification**
+   - Both configs and executables are verified via SHA-256 hashes
+   - Changes to either require re-registration
+   - Prevents tampering with registered extensions
+
+2. **Execution Safety**
+   - Extensions run with user permissions
+   - Timeout constraints prevent runaway processes
+   - Environment variables can be controlled via config
+
+3. **Best Practices**
+   - Review extension code before installation
+   - Keep executables in protected directories
+   - Use absolute paths in configurations
+   - Implement proper error handling in scripts
+   - Regular security audits of registered extensions
+
+## Troubleshooting
+
+### Common Issues
+1. **Registration Failures**
+   - Verify file permissions
+   - Check executable paths
+   - Validate YAML syntax
+
+2. **Execution Errors**
+   - Check operation exists in config
+   - Verify timeout settings
+   - Monitor system resources
+   - Check extension logs
+
+3. **Output Issues**
+   - Verify output method configuration
+   - Check file permissions for file output
+   - Monitor disk space for file operations
+
+### Debug Tips
+1. Enable verbose logging when available
+2. Check system logs for execution errors
+3. Verify extension dependencies
+4. Test extensions with minimal configurations first

+## The Fabric Web App
+[Installing](#Installing)|[Todos](#Todos)|[Collaborators](#Collaborators)
+
+This is the web app for Fabric. It is built using [Svelte](https://svelte.dev/), [SkeletonUI](https://skeleton.dev/), and [Mdsvex](https://mdsvex.pngwn.io/). 
+
+The goal of this app is to not only provide a user interface for Fabric, but also a out-of-the-box website for those who want to get started with web development or blogging. The tech stack is minimal and (I hope) the code is easy to read and understand. One thing I kept in mind when making this app was to make it easy for beginners to get started with web development. You can use this app as a GUI interface for Fabric, a ready to go blog-site, or a website template for your own projects. I hope you find it useful!
+
+![Preview](static/image.png)
+
+### Installing
+It can be installed by navigating to the `web` directory and using `npm install`, `pnpm install`, or your favorite package manager. Then simply run `npm run dev` or your equivalent command to start the app. *You will need to run fabric in a seperate terminal with the `fabric --serve` command.*

+
+Everything you need to build a Svelte project, powered by [`create-svelte`](https://github.com/sveltejs/kit/tree/main/packages/create-svelte).
+
+## Creating a project
+
+If you're seeing this, you've probably already done this step. Congrats!
+
+```bash
+# create a new project in the current directory
+npm create svelte@latest
+
+# create a new project in my-app
+npm create svelte@latest my-app
+```
+
+## Developing
+
+Once you've created a project and installed dependencies with `npm install` (or `pnpm install` or `yarn`), start a development server:
+
+```bash
+npm run dev
+
+# or start the server and open the app in a new browser tab
+npm run dev -- --open
+```
+
+## Building
+
+To create a production version of your app:
+
+```bash
+npm run build
+```
+
+You can preview the production build with `npm run preview`.
+
+> To deploy your app, you may need to install an [adapter](https://kit.svelte.dev/docs/adapters) for your target environment.
