# Agent MD Refactor

Refactor bloated agent instruction files (AGENTS.md, CLAUDE.md, COPILOT.md, etc.) to follow **progressive disclosure principles** - keeping essentials at root and organizing the rest into linked, categorized files.

---

## Triggers

Use this skill when:
- "refactor my AGENTS.md" / "refactor my CLAUDE.md"
- "split my agent instructions"
- "organize my CLAUDE.md file"
- "my AGENTS.md is too long"
- "progressive disclosure for my instructions"
- "clean up my agent config"

## Quick Reference

| Phase | Action | Output |
|-------|--------|--------|
| 1. Analyze | Find contradictions | List of conflicts to resolve |
| 2. Extract | Identify essentials | Core instructions for root file |
| 3. Categorize | Group remaining instructions | Logical categories |
| 4. Structure | Create file hierarchy | Root + linked files |
| 5. Prune | Flag for deletion | Redundant/vague instructions |

---

## Process

### Phase 1: Find Contradictions

Identify any instructions that conflict with each other.

**Look for:**
- Contradictory style guidelines (e.g., "use semicolons" vs "no semicolons")
- Conflicting workflow instructions
- Incompatible tool preferences
- Mutually exclusive patterns

**For each contradiction found:**

## Contradiction Found

**Instruction A:** [quote]
**Instruction B:** [quote]

**Question:** Which should take precedence, or should both be conditional?

Ask the user to resolve before proceeding.

---

### Phase 2: Identify the Essentials

Extract ONLY what belongs in the root agent file. The root should be minimal - information that applies to **every single task**.

**Essential content (keep in root):**
| Category | Example |
|----------|---------|
| Project description | One sentence: "A React dashboard for analytics" |
| Package manager | Only if not npm (e.g., "Uses pnpm") |
| Non-standard commands | Custom build/test/typecheck commands |
| Critical overrides | Things that MUST override defaults |
| Universal rules | Applies to 100% of tasks |

**NOT essential (move to linked files):**
- Language-specific conventions
- Testing guidelines
- Code style details
- Framework patterns
- Documentation standards
- Git workflow details

---

### Phase 3: Group the Rest

Organize remaining instructions into logical categories.

**Common categories:**
| Category | Contents |
|----------|----------|
| typescript.md | TS conventions, type patterns, strict mode rules |
| testing.md | Test frameworks, coverage, mocking patterns |
| code-style.md | Formatting, naming, comments, structure |
| git-workflow.md | Commits, branches, PRs, reviews |
| architecture.md | Patterns, folder structure, dependencies |
| api-design.md | REST/GraphQL conventions, error handling |
| security.md | Auth patterns, input validation, secrets |
| performance.md | Optimization rules, caching, lazy loading |

**Grouping rules:**
1. Each file should be self-contained for its topic
2. Aim for 3-8 files (not too granular, not too broad)
3. Name files clearly: {topic}.md
4. Include only actionable instructions

---

### Phase 4: Create the File Structure

**Output structure:**

project-root/
├── CLAUDE.md (or AGENTS.md)     # Minimal root with links
└── .claude/                      # Or docs/agent-instructions/
    ├── typescript.md
    ├── testing.md
    ├── code-style.md
    ├── git-workflow.md
    └── architecture.md

**Root file template:**

# Project Name

One-sentence description of the project.

## Quick Reference

- **Package Manager:** pnpm
- **Build:** pnpm build
- **Test:** pnpm test
- **Typecheck:** pnpm typecheck

## Detailed Instructions

For specific guidelines, see:
- [TypeScript Conventions](.claude/typescript.md)
- [Testing Guidelines](.claude/testing.md)
- [Code Style](.claude/code-style.md)
- [Git Workflow](.claude/git-workflow.md)
- [Architecture Patterns](.claude/architecture.md)

**Each linked file template:**

# {Topic} Guidelines

## Overview
Brief context for when these guidelines apply.

## Rules

### Rule Category 1
- Specific, actionable instruction
- Another specific instruction

### Rule Category 2
- Specific, actionable instruction

## Examples

### Good
\\\typescript
// Example of correct pattern
\\\

### Avoid
\\\typescript
// Example of what not to do
\\\

---

### Phase 5: Flag for Deletion

Identify instructions that should be removed entirely.

**Delete if:**
| Criterion | Example | Why Delete |
|-----------|---------|------------|
| Redundant | "Use TypeScript" (in a .ts project) | Agent already knows |
| Too vague | "Write clean code" | Not actionable |
| Overly obvious | "Don't introduce bugs" | Wastes context |
| Default behavior | "Use descriptive variable names" | Standard practice |
| Outdated | References deprecated APIs | No longer applies |

**Output format:**

## Flagged for Deletion

| Instruction | Reason |
|-------------|--------|
| "Write clean, maintainable code" | Too vague to be actionable |
| "Use TypeScript" | Redundant - project is already TS |
| "Don't commit secrets" | Agent already knows this |
| "Follow best practices" | Meaningless without specifics |

## Execution Checklist

[ ] Phase 1: All contradictions identified and resolved
[ ] Phase 2: Root file contains ONLY essentials
[ ] Phase 3: All remaining instructions categorized
[ ] Phase 4: File structure created with proper links
[ ] Phase 5: Redundant/vague instructions removed
[ ] Verify: Each linked file is self-contained
[ ] Verify: Root file is under 50 lines
[ ] Verify: All links work correctly

---

## Anti-Patterns

| Avoid | Why | Instead |
|-------|-----|---------|
| Keeping everything in root | Bloated, hard to maintain | Split into linked files |
| Too many categories | Fragmentation | Consolidate related topics |
| Vague instructions | Wastes tokens, no value | Be specific or delete |
| Duplicating defaults | Agent already knows | Only override when needed |
| Deep nesting | Hard to navigate | Flat structure with links |

---

## Examples

### Before (Bloated Root)

# CLAUDE.md

This is a React project.

## Code Style
- Use 2 spaces
- Use semicolons
- Prefer const over let
- Use arrow functions
... (200 more lines)

## Testing
- Use Jest
- Coverage > 80%
... (100 more lines)

## TypeScript
- Enable strict mode
... (150 more lines)

### After (Progressive Disclosure)

# CLAUDE.md

React dashboard for real-time analytics visualization.

## Commands
- pnpm dev - Start development server
- pnpm test - Run tests with coverage
- pnpm build - Production build

## Guidelines
- [Code Style](.claude/code-style.md)
- [Testing](.claude/testing.md)
- [TypeScript](.claude/typescript.md)

---

## Verification

After refactoring, verify:

1. **Root file is minimal** - Under 50 lines, only universal info
2. **Links work** - All referenced files exist
3. **No contradictions** - Instructions are consistent
4. **Actionable content** - Every instruction is specific
5. **Complete coverage** - No instructions were lost (unless flagged for deletion)
6. **Self-contained files** - Each linked file stands alone
