What is This?

Bun Sticky scores your project's AI-readiness. Drop a project.faf file in your repo and AI tools (Claude, Cursor, Copilot) instantly understand your project.

FAF (Foundational AI-context Format) is an IANA-registered format — project DNA for AI assistants.

Also available as a Zig-native parser — 2.7KB WASM. Bun is built on Zig.

Try It

No install needed:

bunx bun-sticky score     # Score your project
bunx bun-sticky init myapp  # Create project.faf
bunx bun-sticky sync      # Sync to CLAUDE.md

Or install globally:

bun install -g bun-sticky

Scoring

21 slots across 5 categories. Type-aware — a CLI scores differently than a fullstack app:

| Type | Slots | Categories | |------|-------|------------| | CLI | 9 | project + human | | Library | 9 | project + human | | API | 17 | project + backend + universal + human | | Webapp | 16 | project + frontend + universal + human | | Fullstack | 21 | all |

Score = Filled Slots / Applicable Slots × 100

Tiers

| Score | Tier | |-------|------| | 100% | 🏆 Trophy | | 99%+ | 🥇 Gold | | 95%+ | 🥈 Silver | | 85%+ | 🥉 Bronze | | 70%+ | 🟢 Green | | 55%+ | 🟡 Yellow | | <55% | 🔴 Red |

Speed

• Cold start: <50ms
• Score command: <100ms
• Zero dependencies: Pure Bun APIs
