# Regenerate copilot-instructions.md

Regenerate the `.github/copilot-instructions.md` file for GitHub Copilot integration, analyzing current project state while preserving team directives and organizational requirements.

**Hook file approach (default):** Generates `AIWG-copilot.md` and adds `@AIWG-copilot.md` directive to copilot-instructions.md if @-link is supported. Note: Copilot @-link support is unverified — defaults to full inject until confirmed (see #444).

**Full inject (`--full-inject`):** Embeds AIWG content inline with AIWG markers.

**Vendor-specific filtering:** This command includes ONLY GitHub Copilot patterns and agent references, reducing context pollution. Other vendor content is referenced but not inlined.

## Core Principle

**Team content is preserved. AIWG content is updated. Only Copilot-specific content is inlined.**

## Parameters

| Flag | Description |
|------|-------------|
| `--no-backup` | Skip creating backup file |
| `--dry-run` | Preview changes without writing |
| `--show-preserved` | List all detected preserved content and exit |
| `--full` | Full regeneration, preserve nothing (destructive) |

## Execution Steps

### Step 1: Create Backup

Unless `--no-backup` specified:

1. Check if `.github/copilot-instructions.md` exists
2. If exists, copy to `.github/copilot-instructions.md.backup-{YYYYMMDD-HHMMSS}`
3. Report backup location

### Step 2: Extract Preserved Content

Same preservation patterns as other platforms:

1. **Explicit Preserve Blocks**: `<!-- PRESERVE -->` ... `<!-- /PRESERVE -->`
2. **Preserved Section Headings**: Team *, Org *, Definition of Done, etc.
3. **Inline Directives**: Lines with directive keywords

### Step 3: Analyze Project

- Languages and package managers
- Development commands
- Test framework
- CI/CD configuration (especially `.github/workflows/`)
- Directory structure
- Existing `.github/agents/` configuration

### Step 4: Detect AIWG State

Check installed frameworks by scanning:
- `.github/agents/` for custom agents (YAML format)
- `.github/copilot/` for Copilot configuration
- `.github/workflows/` for CI/CD workflows

Read registry for framework versions.

### Step 5: Generate copilot-instructions.md

**Document Structure:**

```markdown
# GitHub Copilot Instructions

Project instructions for GitHub Copilot AI assistance.

## Project Overview

{Description from README.md or package.json}

## Tech Stack

- **Language**: {detected languages}

## AIWG Framework Integration

This project uses AIWG SDLC framework with GitHub Copilot.

### Custom Agents

**Agents are deployed to `.github/agents/` as YAML files.**

Invoke via @-mention in Copilot Chat:

```text
@architecture-designer Design system architecture for authentication
@security-architect Review security implementation
@test-engineer Generate comprehensive test suite
@code-reviewer Review pull request for quality
```

**Available agents:**
- `architecture-designer` - System architecture and technical decisions
- `security-architect` - Security design and threat modeling
- `test-engineer` - Test suite creation and strategy
- `code-reviewer` - Code quality and security review
- `devops-engineer` - CI/CD and deployment automation
- `project-manager` - Project planning and tracking

**Full agent catalog:** .github/agents/ or @~/.local/share/ai-writing-guide/agentic/code/frameworks/sdlc-complete/agents/

### Copilot Coding Agent

For automated issue resolution:
1. Navigate to an issue in GitHub
2. Assign to **Copilot**
3. Copilot analyzes and creates a PR

### Natural Language Workflow Requests

Request AIWG workflows using natural language in Copilot Chat:

| Request | Maps To |
|---------|---------|
| "run security review" | flow-security-review-cycle |
| "check project status" | project-status |
| "transition to elaboration" | flow-inception-to-elaboration |
| "start iteration 2" | flow-iteration-dual-track |
| "generate tests for auth" | generate-tests + test-engineer |
| "review this PR" | pr-review + code-reviewer |

**Full workflow patterns:** @~/.local/share/ai-writing-guide/agentic/code/frameworks/sdlc-complete/docs/simple-language-translations.md

<!--
  Add team-specific notes below.
  Content in preserved sections survives regeneration.

```

### Step 6: Write Output

**If `--dry-run`:** Display content, do not write.

**Otherwise:**
1. Ensure `.github/` directory exists
2. Write to `.github/copilot-instructions.md`
3. Report summary

```
