+
+This file provides guidance to Claude Code when working with code in this repository.
+
+## Project Overview
+
+**harness-engineering** is a Claude Code plugin and reference for AI coding agent harnesses. It provides two skills (`/readiness` and `/setup`) that analyze and configure projects for agent-assisted development, plus a README mapping 20+ best practices from industry sources.
+
+### Core Features
+
+- **`/readiness`**: Scores a codebase across 8 pillars and 5 maturity levels, produces a saved report with delta tracking
+- **`/setup`**: Scaffolds CLAUDE.md files, enforcement scripts, git hooks, linter configs, and agent settings via Socratic questioning
+- **Reference guide**: Maps best practices from OpenAI, Anthropic, Augment Code, Factory.ai, and practitioners to concrete implementation patterns
+
+---
+
+## Essential Commands
+
+### Testing
+```bash
+node --experimental-vm-modules node_modules/.bin/jest tests/scripts/   # Unit tests for setup scripts
+bash tests/evals/run-evals.sh                                          # E2E evals against fixture projects
+node tests/evals/grader.js                                             # Grade eval results
+bash tests/evals/test-marketplace-install.sh                           # Test plugin install flow
+```
+
+### Validation
+```bash
+node skills/setup/scripts/lib/generate-docs.js --check   # Verify auto-generated sections are current
+node skills/setup/scripts/lib/validate-docs.js --full     # Check for documentation drift
+```

+
+### Data Flow
+
+```
+User installs plugin
+  -> /readiness reads templates/references as benchmark
+  -> 3 parallel subagents evaluate project against 8 pillars
+  -> Scored report saved to .claude/readiness-report.md
+
+User runs /setup
+  -> Socratic questions determine stack and goals
+  -> Scripts scaffold project structure, configs, hooks
+  -> Enforcement scripts copied to target project's scripts/
+  -> Git hooks wired to run enforcement on every commit/push
+```

+
+## Key Modules
+
+| Module | Purpose |
+|--------|---------|
+| `skills/readiness/SKILL.md` | Full evaluation framework, 8 pillars, 37 criteria, 3 subagent dispatch |
+| `skills/setup/SKILL.md` | 6-phase setup orchestrator with Socratic discovery |
+| `scripts/init-project.js` | Node/TS project scaffolding (package.json, tsconfig, directories) |
+| `scripts/install-enforcement.js` | Copies enforcement scripts, hooks, configs into target project |
+| `scripts/generate-claude-md.js` | Generates tailored CLAUDE.md from templates |
+| `scripts/lib/check-secrets.js` | Pattern-matches API keys, tokens, private keys in staged files |
+| `scripts/lib/check-file-sizes.js` | Rejects files over 300 lines |
+| `scripts/lib/check-test-colocation.js` | Verifies source files have colocated test files |
+| `scripts/lib/generate-docs.js` | Auto-regenerates CLAUDE.md sections between AUTO markers |
+| `scripts/lib/validate-docs.js` | Detects drift between source code and CLAUDE.md content |
+
+---
+
+## Critical Gotchas
+
+- **SKILL.md is the skill**: Claude Code reads the SKILL.md file as the skill prompt. Changes to SKILL.md directly change skill behavior.
+- **Scripts run in target projects, not this repo**: The enforcement scripts in `skills/setup/scripts/` are templates copied into user projects by `/setup`. They must work standalone with zero dependencies on this repo.
+- **Eval fixtures are intentionally broken**: `tests/evals/fixtures/level-1-bare/` contains a hardcoded secret on purpose for detection testing. Do not "fix" it.
+- **No package.json at root**: This is a Claude Code plugin, not an npm package. Tests run via direct node/jest/bash invocation.
+- **`globs:` not `paths:`**: Rule files use `globs:` in YAML frontmatter for path scoping. The official docs say `paths:` but `globs:` works more reliably (see Claude Code issue #17204).
