[FAF](https://faf.one) (Foundational AI-context Format) is an [IANA-registered](https://www.iana.org/assignments/media-types/application/vnd.faf+yaml) format — project DNA for AI assistants. ## v2.1 — Sticky Stars - **Star nudge** — a tasteful, throttled star-ask at a top-tier score (95%+), so a tool people quietly use finally gets the stars it earns. Interactive terminals only; opt out with `BUN_STICKY_NO_NUDGE`. - **faf-wasm-core** embedded — Mk4 Rust WASM kernel (322KB), 284μs per score - **Data-driven slotignore** — the `.faf` file carries the scoring truth - **377 tests** across 4 suites, zero dependencies ## Try It No install needed: ```bash bunx bun-sticky score # Score your project (WASM kernel) bunx bun-sticky wasm-score # Score with detailed WASM output bunx bun-sticky bench # Benchmark: 284μs per score bunx bun-sticky badge # Get your mcpaas.live badge bunx bun-sticky init myapp # Create project.faf bunx bun-sticky sync # Sync to CLAUDE.md bunx bun-sticky version # Show version bunx bun-sticky help # All commands ``` Or install globally: ```bash bun install -g bun-sticky ``` > **Star nudge:** at a top-tier score (95%+), Bun Sticky shows a one-line star-ask — interactive terminals only, capped at 3 shows and throttled to 30 days, silent in CI. Silence it entirely with `BUN_STICKY_NO_NUDGE=1`. ## Scoring 21 slots across 5 categories. Data-driven — the `.faf` file carries the truth: - **populated** — slot has a value (counts toward score) - **empty** — slot is missing (counts against score) - **slotignored** — slot doesn't apply to this project type (excluded from denominator) **Score = Populated / Active × 100** where Active = Total - Ignored A CLI project marks frontend/backend slots as `slotignored` in the .faf file itself. Every engine reads the same file, skips the same slots, gets the same score. ## Tiers | Score | Tier | |-------|------| | 100% | 🏆 Trophy | | 99%+ | ★ Gold | | 95%+ | ◆ Silver | | 85%+ | ◇ Bronze | | 70%+ | ● Green | | 55%+ | ● Yellow | | <55% | ○ Red | ## Speed - **WASM score**: 284μs average (Mk4 Rust kernel) - **Cold start**: <50ms - **Zero dependencies**: Pure Bun APIs - **TypeScript native**: No build step - **322KB**: Embedded WASM binary ## Testing 377 tests across 4 suites. Full Bun test API coverage. ```bash bun test ``` ## The Kernel bun-sticky embeds [faf-wasm-core](https://github.com/Wolfe-Jam/faf-wasm-core) — a kernel router that wraps the published Rust WASM behind a `FafKernel` interface. Rust today, Zig Cascade tomorrow. Same interface, no consumer changes. ```typescript import { init } from "./lib/core"; const kernel = await init("rust"); // or "zig" when Cascade ships const result = kernel.score(yaml); // Same interface. Any engine. ``` Same interface, any engine. One kernel, one truth. ## Want More? bun-sticky scores your project. **faf-cli** is the full toolchain — 33 MCP tools, bi-sync, tri-sync, and more. ```bash bunx faf-cli auto # Bun npx faf-cli auto # npm brew install faf-cli && faf auto # Homebrew ``` ## FAF Ecosystem Part of [FAF](https://faf.one) — 115,000+ downloads across npm, PyPI, and crates.io.
