Fetch Available Instructions: Extract instruction list and descriptions from awesome-copilot README.instructions.md. Must use #fetch tool.
Scan Local Instructions: Discover existing instruction files in .github/instructions/ folder
Extract Descriptions: Read front matter from local instruction files to get descriptions and applyTo patterns
Fetch Remote Versions: For each local instruction, fetch the corresponding version from awesome-copilot repository using raw GitHub URLs (e.g., https://raw.githubusercontent.com/github/awesome-copilot/main/instructions/<filename>)
Compare Versions: Compare local instruction content with remote versions to identify:
- Instructions that are up-to-date (exact match)
- Instructions that are outdated (content differs)
- Key differences in outdated instructions (description, applyTo patterns, content)
Analyze Context: Review chat history, repository files, and current project needs
Compare Existing: Check against instructions already available in this repository
Match Relevance: Compare available instructions against identified patterns and requirements
Present Options: Display relevant instructions with descriptions, rationale, and availability status including outdated instructions
Validate: Ensure suggested instructions would add value not already covered by existing instructions
Output: Provide structured table with suggestions, descriptions, and links to both awesome-copilot instructions and similar local instructions AWAIT user request to proceed with installation or updates of specific instructions. DO NOT INSTALL OR UPDATE UNLESS DIRECTED TO DO SO.
Download/Update Assets: For requested instructions, automatically:
- Download new instructions to .github/instructions/ folder
- Update outdated instructions by replacing with latest version from awesome-copilot
- Do NOT adjust content of the files
- Use #fetch tool to download assets, but may use curl using #runInTerminal tool to ensure all content is retrieved
- Use #todos tool to track progress

Context Analysis Criteria

🔍 Repository Patterns:

Programming languages used (.cs, .js, .py, .ts, etc.)
Framework indicators (ASP.NET, React, Azure, Next.js, etc.)
Project types (web apps, APIs, libraries, tools)
Development workflow requirements (testing, CI/CD, deployment)

🗨️ Chat History Context:

Recent discussions and pain points
Technology-specific questions
Coding standards discussions
Development workflow requirements

Output Format

Display analysis results in structured table comparing awesome-copilot instructions with existing repository instructions:

Awesome-Copilot Instruction	Description	Already Installed	Similar Local Instruction	Suggestion Rationale
blazor.instructions.md	Blazor development guidelines	✅ Yes	blazor.instructions.md	Already covered by existing Blazor instructions
reactjs.instructions.md	ReactJS development standards	❌ No	None	Would enhance React development with established patterns
java.instructions.md	Java development best practices	⚠️ Outdated	java.instructions.md	applyTo pattern differs: remote uses `'*/.java'` vs local `'*.java'` - Update recommended

Local Instructions Discovery Process

List all *.instructions.md files in the instructions/ directory
For each discovered file, read front matter to extract description and applyTo patterns
Build comprehensive inventory of existing instructions with their applicable file patterns
Use this inventory to avoid suggesting duplicates

Version Comparison Process

For each local instruction file, construct the raw GitHub URL to fetch the remote version:
- Pattern: https://raw.githubusercontent.com/github/awesome-copilot/main/instructions/<filename>
Fetch the remote version using the #fetch tool
Compare entire file content (including front matter and body)
Identify specific differences:
- Front matter changes (description, applyTo patterns)
- Content updates (guidelines, examples, best practices)
Document key differences for outdated instructions
Calculate similarity to determine if update is needed

File Structure Requirements

Based on GitHub documentation, copilot-instructions files should be:

Repository-wide instructions: .github/copilot-instructions.md (applies to entire repository)
Path-specific instructions: .github/instructions/NAME.instructions.md (applies to specific file patterns via applyTo frontmatter)
Community instructions: instructions/NAME.instructions.md (for sharing and distribution)

Front Matter Structure

Instructions files in awesome-copilot use this front matter format:

---
description: 'Brief description of what this instruction provides'
applyTo: '**/*.js,**/*.ts' # Optional: glob patterns for file matching
---

Requirements

Use githubRepo tool to get content from awesome-copilot repository instructions folder
Scan local file system for existing instructions in .github/instructions/ directory
Read YAML front matter from local instruction files to extract descriptions and applyTo patterns
Compare local instructions with remote versions to detect outdated instructions
Compare against existing instructions in this repository to avoid duplicates
Focus on gaps in current instruction library coverage
Validate that suggested instructions align with repository's purpose and standards
Provide clear rationale for each suggestion
Include links to both awesome-copilot instructions and similar local instructions
Clearly identify outdated instructions with specific differences noted
Consider technology stack compatibility and project-specific needs
Don't provide any additional information or context beyond the table and the analysis

Icons Reference

✅ Already installed and up-to-date
⚠️ Installed but outdated (update available)
❌ Not installed in repo

Update Handling

When outdated instructions are identified:

Include them in the output table with ⚠️ status
Document specific differences in the "Suggestion Rationale" column
Provide recommendation to update with key changes noted
When user requests update, replace entire local file with remote version
Preserve file location in .github/instructions/ directory
