docs(claude-md): dogfood /sync-claude-md on root CLAUDE.md

Splits the 518-line root CLAUDE.md into a 70-line root plus four chained
sub-files (skill/, command/, agent/, docs/), all under the 150-line cap,
and prunes stale references uncovered by the audit.

- CLAUDE.md (518 -> 70): project overview, navigation with @-imports,
  behavioural guidelines summary, naming reference, license link
- skill/CLAUDE.md (85): component flow, Python module architecture,
  modifying modules, adding templates, tech-stack detection, quality
  scoring, karpathy skill
- command/CLAUDE.md (38): slash command development, top-level .md install
  layout, skill <-> command integration
- agent/CLAUDE.md (70): guardian frontmatter, hook responsibilities,
  skill <-> agent integration, git triggers
- docs/CLAUDE.md (109): install verification, smoke test, manual e2e
  tests, common operations, release process

Stale content removed:
- 'Dual Directory Structure' section (claude-md-enhancer/ legacy dir
  does not exist on disk)
- '20-300 lines' / '300-line cap' references rewritten to 150
- '~/.claude/commands/enhance-claude-md/' bundle paths rewritten to
  top-level '.md' files (matching the new installer layout)
- 'Three integrated components' updated to five
- 'Current Version: 2.0.0' updated to 2.1.0
- '6 examples' in sample_input.json claim corrected (file has 1 scenario)

Each sub-file opens with a markdown back-link and @../CLAUDE.md import;
root contains @-imports for all four sub-files. Validator passes (status
pass) for every file.

Top-level guidance for Claude Code when working on this repository.
## Project Overview
**ClaudeForge** is a Claude Code plugin (manifest at `.claude-plugin/plugin.json`) and standalone toolkit for the CLAUDE.md lifecycle: initialise, enhance, sync, and modularise CLAUDE.md files with a hard 150-line cap, automatic chaining via `@path` imports, and Karpathy behavioural guardrails. Works in any Claude Code or Claude.cowork project. The repository consists of five integrated components:
**ClaudeForge** is a Claude Code plugin (manifest at `.claude-plugin/plugin.json`) and standalone toolkit for the CLAUDE.md lifecycle: initialise, enhance, sync, and modularise files with a hard **150-line cap**, automatic chaining via `@path` imports, and Karpathy behavioural guardrails. Works in any Claude Code or Claude.cowork project.
1. **Skill** (`claudeforge-skill`) - Core Python modules for analysis, generation, and validation. Enforces a 150-line hard cap per CLAUDE.md.
2. **Slash Command** (`/enhance-claude-md`) - Interactive multi-phase discovery workflow. Delegates deep codebase scans to the Explore subagent to avoid context bloat.
3. **Slash Command** (`/sync-claude-md`) - Walks every CLAUDE.md in the project, prunes stale references, enforces the 150-line cap, and repairs the root ↔ subdirectory chain (markdown links + `@path` imports).
4. **Guardian Agent** (`claude-md-guardian`) - Background maintenance agent
5. **Karpathy Guidelines Skill** (`karpathy-guidelines`) - Behavioral guardrails embedded into every generated CLAUDE.md and installed as a standalone skill, adapted with attribution from the MIT-licensed [forrestchang/andrej-karpathy-skills](https://github.com/forrestchang/andrej-karpathy-skills) repository
Five components ship in this repo:
---
1. **Skill** (`claudeforge-skill`, in `skill/`) — Python modules for analysis, generation, validation. Enforces the 150-line cap.
2. **Slash command** (`/enhance-claude-md`, in `command/`) — interactive init/enhance workflow. Delegates deep codebase scans to the Explore subagent.
3. **Slash command** (`/sync-claude-md`, in `command/`) — walks every CLAUDE.md, prunes stale references, enforces the 150-line cap, repairs the root ↔ sub chain.
4. **Guardian agent** (`claude-md-guardian`, in `agent/`) — background sync triggered by `SessionStart` / `PreToolUse` / `PostToolUse` hooks.
5. **Karpathy guidelines skill** (`karpathy-guidelines`, in `skill/karpathy-guidelines/`) — behavioural guardrails embedded into every generated CLAUDE.md. Adapted with attribution from the MIT-licensed [forrestchang/andrej-karpathy-skills](https://github.com/forrestchang/andrej-karpathy-skills) repo.

### Component Interaction Flow
## Behavioral Guidelines
```
User Project
/enhance-claude-md (Slash Command)
[Phase 1: Discovery] → [Phase 2: Analysis] → [Phase 3: Task]
claude-md-guardian (Agent) OR Direct Skill Invocation
claudeforge-skill (Python Modules)
workflow.py → analyzer.py → validator.py → template_selector.py → generator.py
CLAUDE.md Created/Updated with 100% Native Format
```
Behavioural guardrails applied to every coding, review, and refactoring task in this repo. Full skill: `~/.claude/skills/karpathy-guidelines/SKILL.md`.
### Python Module Architecture
1. **Think before coding.** State load-bearing assumptions; if a request has multiple reasonable interpretations, surface them instead of picking silently. Stop and ask when something is genuinely unclear.
2. **Simplicity first.** Write the minimum code that solves the stated problem. No speculative abstractions, no unrequested configuration, no error handling for conditions that cannot occur.
3. **Surgical changes.** Touch only what the task requires. Match surrounding style. Every changed line should trace directly to the user's request.
4. **Goal-driven execution.** Convert vague requests into verifiable success criteria before coding (failing test first), and state a step-by-step plan with per-step verification for multi-step work.
The skill consists of 5 core modules (~2,190 lines):
**workflow.py (432 lines)** - `InitializationWorkflow` class
- Orchestrates interactive initialization for new projects
- Methods: `check_claude_md_exists()`, `generate_exploration_prompt()`, `analyze_discoveries()`
- Detects: project type, tech stack, team size, development phase, workflows
- Returns: Project context dictionary for template selection
**analyzer.py (382 lines)** - `CLAUDEMDAnalyzer` class
- Analyzes existing CLAUDE.md files
- Methods: `analyze_file()`, `detect_sections()`, `calculate_quality_score()`, `generate_recommendations()`
- Quality scoring: 0-100 based on length (25pts), completeness (25pts), formatting (20pts), specificity (15pts), modularity (15pts)
- Returns: Analysis report with quality score and actionable recommendations
**validator.py (429 lines)** - `BestPracticesValidator` class
- Validates against Anthropic guidelines
- Methods: `validate_length()`, `validate_structure()`, `validate_formatting()`, `validate_completeness()`, `validate_all()`
- Checks: file length (20-300 lines), required sections, markdown formatting, anti-patterns
- Returns: Validation report with pass/fail status and detailed issues
**template_selector.py (467 lines)** - `TemplateSelector` class
- Selects appropriate template based on context
- Methods: `select_template()`, `customize_template()`, `recommend_modular_structure()`
- Logic: Maps project type + team size → template complexity
- Returns: Template configuration with target line count and modular recommendation
**generator.py (480 lines)** - `ContentGenerator` class
- Generates new or enhanced CLAUDE.md content
- Methods: `generate_root_file()`, `generate_context_file()`, `generate_section()`, `merge_with_existing()`
- Supports: Root files, context-specific files (backend/, frontend/, database/), individual sections
- Returns: Complete CLAUDE.md content with 100% native format compliance
### Critical Validation Rule
All generated CLAUDE.md files MUST include:
- Project structure (ASCII tree diagram)
- File structure explanations
- Setup & installation instructions
- Architecture section (for complex projects)
- Validation against `/update-claude-md` slash command format
- Cross-check against reference examples in `skill/examples/`

## Development Workflow
### Modifying Python Modules
When updating skill modules (analyzer.py, generator.py, etc.):
1. Edit files in `skill/` directory
2. Test changes by reinstalling: `./install.sh` (choose option 2 for project-level testing)
3. Test skill invocation in Claude Code: `/enhance-claude-md`
4. Validate output against reference examples in `skill/examples/`
5. Update `CHANGELOG.md` with changes
### Modifying Slash Command
When updating `/enhance-claude-md` command:
1. Edit `command/enhance-claude-md.md`
2. Key sections to modify:
- **Phase 1 (Discovery)**: Bash commands that check project state
- **Phase 2 (Analysis)**: Logic that determines initialize vs. enhance
- **Phase 3 (Task)**: Skill/agent invocation logic
3. Test by reinstalling command: `cp command/enhance-claude-md.md ~/.claude/commands/enhance-claude-md/`
4. Restart Claude Code and test: `/enhance-claude-md`
### Modifying Guardian Agent
When updating `claude-md-guardian` agent:
1. Edit `agent/claude-md-guardian.md`
2. Key YAML frontmatter fields:
- `permissions`: [Bash, Read, Write, Edit, Grep, Glob, Skill]
- `model`: Set to `haiku` for token efficiency
- `color`: Visual indicator (purple)
- `fork_safe`: Set to `true` for independent execution
- `hooks`: Array of lifecycle hooks (SessionStart, PreToolUse, PostToolUse)
3. Agent workflow phases:
- Phase 1: Assessment (check git changes)
- Phase 2: Analysis (determine scope)
- Phase 3: Update (invoke skill for targeted updates)
4. Test: `cp agent/claude-md-guardian.md ~/.claude/agents/`
**Example Agent Definition with v2.0.0 Syntax:**
```yaml
---
name: claude-md-guardian
permissions: [Bash, Read, Write, Edit, Grep, Glob, Skill]
model: haiku
color: purple
fork_safe: true
hooks:
- SessionStart
- PreToolUse
- PostToolUse
---
```
### Adding New Templates
To add a new reference template (e.g., Rust, mobile):
1. Create new template file in `skill/examples/`
2. Follow native format structure:
- Project structure diagram (ASCII tree)
- Setup & installation
- Architecture section
- Tech-specific guidelines
3. Update `skill/examples/README.md` with new template description
4. Update `template_selector.py` logic to detect when to use new template
5. Add test case in `skill/sample_input.json`
---
## Testing & Validation
### Manual Testing Checklist
**Test New Project Initialization:**
```bash
# 1. Create test project
mkdir test-project && cd test-project
git init
npm init -y # or create package.json
# 2. Run slash command
/enhance-claude-md
# 3. Verify Claude:
# - Explores repository
# - Detects TypeScript/Node project
# - Shows discoveries
# - Asks for confirmation
# - Creates CLAUDE.md with native format
```
**Test Existing Project Enhancement:**
```bash
# 1. Create basic CLAUDE.md
echo "# CLAUDE.md\n\n## Tech Stack\n- TypeScript" > CLAUDE.md
# 2. Run slash command
/enhance-claude-md
# 3. Verify Claude:
# - Analyzes existing file
# - Calculates quality score (0-100)
# - Identifies missing sections (Project Structure, Setup, etc.)
# - Asks to enhance
# - Adds missing native format sections
```
**Test Guardian Agent:**
```bash
# 1. Make significant changes
npm install react # Add new dependency
mkdir src/components # New directory
# 2. Start new Claude Code session (triggers SessionStart)
# 3. Verify agent:
# - Detects changes via git diff
# - Updates CLAUDE.md automatically
# - Reports: "Tech Stack: Added react", "Project Structure: Updated diagram"
```
### Quality Validation
All generated CLAUDE.md files should pass these checks:
```python
# Use validator.py
validator = BestPracticesValidator(content)
results = validator.validate_all()
# Expected passes:
# - File length: 20-300 lines (or modular if >300)
# - Structure: Required sections present
# - Formatting: Valid markdown, proper heading hierarchy
# - Completeness: Code examples, tech stack, workflows
# - Anti-patterns: No hardcoded secrets, no TODOs/placeholders
```

### Important: Dual Directory Structure
## Naming Reference
Note the duplication: `claude-md-enhancer/` (legacy) and `skill/` (current). When making changes:
- **Always edit `skill/`** - This is the active version used by installers
- `claude-md-enhancer/` is kept for reference but not actively maintained
- **Project / display name:** ClaudeForge
- **GitHub:** https://github.com/alirezarezvani/ClaudeForge
- **Skill name (frontmatter):** `claude-md-enhancer` (kept for backwards compatibility); installed as `claudeforge-skill/`
- **Slash commands:** `/enhance-claude-md`, `/sync-claude-md` (names fixed by file name)
- **Agent:** `claude-md-guardian`
- **Standalone skill:** `karpathy-guidelines`

## Common Operations
### Update Reference Templates
```bash
# Edit template
vim skill/examples/python-api-CLAUDE.md
# Test template selection
# 1. Create test project matching template criteria
mkdir test-python-api && cd test-python-api
echo "fastapi" > requirements.txt
# 2. Run slash command and verify template is used
/enhance-claude-md
```
### Update Quality Scoring Logic
```bash
# Edit analyzer.py
vim skill/analyzer.py
# Update calculate_quality_score() method
# Current scoring breakdown:
# - length_appropriateness: 25 points (20-300 lines ideal)
# - section_completeness: 25 points (required sections present)
# - formatting_quality: 20 points (markdown, headings, code blocks)
# - content_specificity: 15 points (project-specific, not generic)
# - modular_organization: 15 points (context files if needed)
# Test scoring
python3 -c "
from skill.analyzer import CLAUDEMDAnalyzer
with open('test-CLAUDE.md') as f:
analyzer = CLAUDEMDAnalyzer(f.read())
report = analyzer.analyze_file()
print(f'Quality Score: {report[\"quality_score\"]}/100')
"
```
### Update Installer Scripts
```bash
# Edit installer
vim install.sh # or install.ps1
# Key sections:
# - Installation paths (user-level vs project-level)
# - Component copying (skill, command, agent)
# - Backup logic (existing installations)
# - Quality hooks installation (optional)
# Test installer
./install.sh
# Choose test option and verify all components copied correctly
```
---
## Integration Points
### Skill ↔ Slash Command
The slash command invokes the skill via:
```markdown
# In command/enhance-claude-md.md, Phase 3:
I can invoke the `claude-md-enhancer` skill directly to handle the appropriate workflow based on what I discovered above.
```
Claude Code recognizes the skill name `claude-md-enhancer` and calls Python modules.
### Skill ↔ Guardian Agent
The agent uses the skill as its core capability:
```yaml
# In agent/claude-md-guardian.md:
permissions: [Bash, Read, Write, Edit, Grep, Glob, Skill]
hooks:
- SessionStart # Detects project changes on session start
- PreToolUse # Validates before tool execution
- PostToolUse # Validates after CLAUDE.md updates
```
Agent invokes skill with: `Skill: claude-md-enhancer` in agent workflow.
**Example Hook Usage:**
```markdown
# When SessionStart hook triggers:
1. Check git diff for changes
2. If significant changes detected → invoke skill
3. Update CLAUDE.md automatically
# When PostToolUse hook triggers after Edit/Write to CLAUDE.md:
1. Validate updated content with validator.py
2. Report quality score
3. Suggest improvements if needed
```
### Agent ↔ Git
Agent detects changes via git commands:
```bash
git diff --name-status HEAD~10
git log --since="1 week ago" --oneline --no-merges
git diff HEAD~10 -- package.json requirements.txt
```
Triggers update when:
- 5+ files modified
- New dependencies added
- New directories created
- Manual invocation after milestone
---
## Tech Stack Detection Logic
The workflow and template selector detect tech stacks via:
**Frontend Detection:**
- React: `package.json` contains `"react"`
- Vue: `package.json` contains `"vue"`
- Angular: `angular.json` exists
- TypeScript: `tsconfig.json` exists
**Backend Detection:**
- Node.js: `package.json` exists
- Python: `requirements.txt`, `pyproject.toml`, `setup.py`
- Go: `go.mod` exists
- Java: `pom.xml`, `build.gradle`
- Rust: `Cargo.toml` exists
**Database Detection:**
- PostgreSQL: `package.json` or `requirements.txt` contains "pg" or "psycopg2"
- MongoDB: Contains "mongoose" or "pymongo"
- Redis: Contains "redis" or "ioredis"
Update detection logic in: `skill/workflow.py``_detect_tech_stack()` method
---
## Repository Naming
**Project Name:** ClaudeForge
**GitHub URL:** https://github.com/alirezarezvani/ClaudeForge
**Skill Name:** `claudeforge-skill` (installed as directory name)
**Slash Command:** `/enhance-claude-md` (fixed name, cannot be changed by user)
**Agent Name:** `claude-md-guardian` (file name)
When updating references:
- `skill/SKILL.md` → YAML frontmatter `name: claude-md-enhancer` (kept for compatibility)
- `README.md` → Use "ClaudeForge" as display name
- `install.sh` → Copies to `claudeforge-skill/` directory
- Internal documentation → Use "ClaudeForge" consistently
---
## Version Management
**Current Version:** 2.0.0 (see CHANGELOG.md)
**Versioning:** Semantic Versioning (MAJOR.MINOR.PATCH)
When releasing new version:
1. Update `CHANGELOG.md` with changes under new version header
2. Update version in `README.md` badge
3. Update version in `skill/SKILL.md` bottom section
4. Create git tag: `git tag -a v2.1.0 -m "Release v2.1.0"`
5. Push tag: `git push origin v2.1.0`
6. Create GitHub release with CHANGELOG excerpt

# Guardian Agent Development
Guidelines for the `claude-md-guardian` background-maintenance agent.
## File
`agent/claude-md-guardian.md` — installs to `~/.claude/agents/claude-md-guardian.md`.
## Modifying the Agent
1. Edit `agent/claude-md-guardian.md`.
2. YAML frontmatter fields to preserve:
- `permissions: [Bash, Read, Write, Edit, Grep, Glob, Skill]`
- `model: haiku` — token efficiency for routine sync runs.
- `color: purple` — visual indicator in Claude Code UI.
- `fork_safe: true` — agent runs independently.
- `hooks: [SessionStart, PreToolUse, PostToolUse]`.
3. Workflow phases inside the agent:
- **Assessment** — read `git diff` / `git status` / changed-file counts.
- **Analysis** — decide if changes are significant enough to update CLAUDE.md.
- **Update** — invoke the skill for targeted section updates rather than full regeneration (~7080% token saving vs. rewrite).
4. Re-install for testing: `cp agent/claude-md-guardian.md ~/.claude/agents/`.
## v2.0.0+ Frontmatter Reference
```yaml
---
name: claude-md-guardian
permissions: [Bash, Read, Write, Edit, Grep, Glob, Skill]
model: haiku
color: purple
fork_safe: true
hooks:
- SessionStart
- PreToolUse
- PostToolUse
---
```
## Skill ↔ Agent Integration
The agent uses `claude-md-enhancer` (the skill's frontmatter name; installed as `claudeforge-skill/`) as its core capability. Invoke it with `Skill: claude-md-enhancer` inside the agent workflow.
Hook responsibilities:
- **SessionStart** — check `git diff`; if significant change is detected, invoke the skill for an incremental update.
- **PreToolUse** — validate before a CLAUDE.md edit lands.
- **PostToolUse** — after Edit/Write to any CLAUDE.md, run `BestPracticesValidator`, report the quality score, suggest improvements. Refuse to leave the file over 150 lines.
## Agent ↔ Git
The agent watches for change signals via:
```bash
git diff --name-status HEAD~10
git log --since="1 week ago" --oneline --no-merges
git diff HEAD~10 -- package.json requirements.txt pyproject.toml go.mod Cargo.toml
```
Triggers an update when any of these hold:
- 5+ files modified since the last sync.
- New dependencies added to a manifest file.
- New top-level directories created (potential new sub-CLAUDE.md candidates).
- Manual invocation after a milestone or release.
When the agent runs sync, it follows `command/sync-claude-md.md`: never commit, leave the diff for the user to review.

# Slash Command Development
Guidelines for the `/enhance-claude-md` and `/sync-claude-md` slash commands.
## Files
- `command/enhance-claude-md.md` — interactive initialise / enhance workflow.
- `command/sync-claude-md.md` — walks every CLAUDE.md, prunes stale references, enforces the 150-line cap, repairs the root ↔ sub chain.
Both install as top-level `~/.claude/commands/<name>.md` so they register as `/enhance-claude-md` and `/sync-claude-md`. There is no `enhance-claude-md/` bundle directory anymore — legacy bundles are backed up automatically on upgrade.
## Modifying `/enhance-claude-md`
1. Edit `command/enhance-claude-md.md`.
2. Key phases:
- **Phase 1 (Discovery)** — bash inventory + Explore-subagent delegation for deep codebase walks. Keep the calling session's context lean.
- **Phase 2 (Analysis)** — branches initialise (no CLAUDE.md) vs. enhance (CLAUDE.md exists).
- **Phase 3 (Task)** — invokes the `claude-md-enhancer` skill or `claude-md-guardian` agent.
3. Always-on requirement: every generated/enhanced CLAUDE.md must include `## Behavioral Guidelines`. The skill inserts it automatically — do not strip it.
4. Re-install for testing: `./install.sh` (project-level) or copy the file manually to `~/.claude/commands/enhance-claude-md.md`.
5. Restart Claude Code (commands hot-reload, but restart guarantees a clean state) and test.
## Modifying `/sync-claude-md`
1. Edit `command/sync-claude-md.md`.
2. Phases: inventory → per-file audit → enforce 150-line cap (split into sub-files via `generator.generate_context_file()`) → re-chain root ↔ subs → cleanup report.
3. Sync should never commit on its own; leave the diff staged-but-uncommitted for the user.
## Skill ↔ Slash Command Integration
`command/enhance-claude-md.md` Phase 3 invokes the skill by name:
> I can invoke the `claude-md-enhancer` skill directly to handle the appropriate workflow based on what I discovered above.
Claude Code resolves `claude-md-enhancer` from the YAML frontmatter `name:` field in `skill/SKILL.md` (kept for backwards compatibility — the installed directory is `claudeforge-skill/`).

## Smoke Test (run from repo root)
```bash
python3 - <<'PY'
import sys; sys.path.insert(0, 'skill')
from validator import BestPracticesValidator
from template_selector import TemplateSelector
from generator import ContentGenerator
assert BestPracticesValidator.MAX_RECOMMENDED_LINES == 150
for cfg in TemplateSelector.TEAM_SIZE_TEMPLATES.values():
assert cfg['target_lines'] <= 150
ctx = {'type':'fullstack','tech_stack':['typescript','python'],
'team_size':'medium','phase':'production','workflows':['cicd']}
out = ContentGenerator(ctx).generate_root_file()
assert len(out.splitlines()) <= 150
assert '## Behavioral Guidelines' in out
print('smoke ok')
PY
```
Run after any change to `skill/`, `command/`, or `agent/`.
## Manual End-to-End Tests
**Fresh project init:**
1. `mkdir test-project && cd test-project && git init && npm init -y`
2. Run `/enhance-claude-md`.
3. Confirm generated CLAUDE.md ≤ 150 lines, contains `## Behavioral Guidelines`, has tech detection right.
**Existing project enhance:**
1. Seed `CLAUDE.md` with one short section.
2. Run `/enhance-claude-md`; confirm quality score reported, missing sections proposed, `## Behavioral Guidelines` appended if absent.
**Guardian agent sync:**
1. Add a new dependency and create a new directory.
2. Open a new Claude Code session — `SessionStart` fires.
3. Confirm the agent updates Tech Stack / Project Structure and quality re-validates.
**Sync command:**
1. In a repo with stale CLAUDE.md references, run `/sync-claude-md`.
2. Confirm stale lines flagged, 150-cap enforced via split, root ↔ sub chain repaired, diff left staged for the user.
## Common Operations
**Update a reference template:** edit `skill/examples/<name>-CLAUDE.md`, then add a matching scenario to `skill/sample_input.json`.
**Update quality scoring:** edit `skill/analyzer.py``calculate_quality_score()`. Re-run the smoke test.
**Update installer:** edit `install.sh` / `install.ps1` (paths, copy logic, backup logic, hooks). Test both user-level and project-level on a throwaway directory.
## Release Process
1. Update `CHANGELOG.md` under a new version header.
2. Bump the version in `README.md`, `skill/SKILL.md`, and `.claude-plugin/plugin.json`.
3. `git tag -a vX.Y.Z -m "Release vX.Y.Z"`.
4. `git push origin vX.Y.Z`.
5. Create the GitHub release with a CHANGELOG excerpt.
Versioning is semver. See `docs/MIGRATION_V2.md` for the v1 → v2 upgrade path.

# Skill Development
Guidelines for the `claudeforge-skill` Python modules and the `karpathy-guidelines` skill.
## Component Interaction Flow
```
User Project
/enhance-claude-md (Slash Command) → Explore subagent (deep scan)
[Discovery] → [Analysis] → [Task]
claude-md-guardian (Agent) OR Direct Skill Invocation
claudeforge-skill (Python Modules)
workflow.py → analyzer.py → validator.py → template_selector.py → generator.py
CLAUDE.md ≤ 150 lines, chained via `@path` imports
```
## Python Module Architecture
Five modules live under `skill/`:
- **`workflow.py`** — `InitializationWorkflow`: orchestrates interactive setup, detects project type / tech stack / team size / phase / workflows, returns a context dict.
- **`analyzer.py`** — `CLAUDEMDAnalyzer`: analyses existing files; quality scoring (0100) across length, completeness, formatting, specificity, modularity.
- **`validator.py`** — `BestPracticesValidator`: checks file length (hard cap 150, warning at 120), required sections, formatting, anti-patterns.
- **`template_selector.py`** — `TemplateSelector`: maps project type + team size to a template; all team-size targets are ≤ 150 lines.
- **`generator.py`** — `ContentGenerator`: writes root + context files, emits `@path` chain imports, prepends sub-file back-links, idempotent `merge_with_existing`.
## Required Output Sections
Every generated CLAUDE.md must contain:
- Project structure (ASCII tree, for projects that need it)
- Setup & installation
- Architecture (for non-trivial projects)
- `## Behavioral Guidelines` (Karpathy summary — inserted automatically)
- Cross-check against reference examples in `skill/examples/`
## Modifying Python Modules
1. Edit files in `skill/`.
2. Run the smoke test (see `docs/CLAUDE.md` → Testing & Validation).
3. Re-install for live testing: `./install.sh` (project-level scope).
4. Test slash command: `/enhance-claude-md`.
5. Validate output against `skill/examples/`.
6. Update `CHANGELOG.md`.
## Adding Reference Templates
1. Add a new file under `skill/examples/`.
2. Follow the native format (project structure, setup, architecture, tech guidelines).
3. Update `skill/examples/README.md`.
4. Teach `template_selector.py` how to detect the new template.
5. Add a scenario to `skill/sample_input.json`.
## Quality Scoring (analyzer.py)
`calculate_quality_score()` breakdown:
- length_appropriateness: 25 pts (50150 lines ideal; the 150-line hard cap is enforced here)
- section_completeness: 25 pts (required sections present)
- formatting_quality: 20 pts (markdown, heading hierarchy, code blocks)
- content_specificity: 15 pts (project-specific, not generic)
- modular_organization: 15 pts (chained sub-files when needed)
## Tech Stack Detection
`skill/workflow.py``_detect_tech_stack()` reads these signals:
- **Frontend** — React/Vue/Angular via `package.json`; Angular via `angular.json`; TypeScript via `tsconfig.json`.
- **Backend** — Node (`package.json`), Python (`requirements.txt` / `pyproject.toml` / `setup.py`), Go (`go.mod`), Java (`pom.xml` / `build.gradle`), Rust (`Cargo.toml`).
- **Database** — Postgres (`pg` / `psycopg2`), MongoDB (`mongoose` / `pymongo`), Redis (`redis` / `ioredis`).
Add new detectors there, not in the template selector.
## Karpathy Guidelines Skill
`skill/karpathy-guidelines/SKILL.md` is the standalone skill installed at `~/.claude/skills/karpathy-guidelines/`. Adapted with attribution from the MIT-licensed [forrestchang/andrej-karpathy-skills](https://github.com/forrestchang/andrej-karpathy-skills) repo. The four principles are inserted automatically into every generated CLAUDE.md via `template_selector._generate_karpathy_guidelines()` and `generator._generate_karpathy_guidelines()`. Do not strip the embedded section during enhancement.
