⏺ Yes, that title is real. Let me explain.
FAF = Foundational AI-context Format (IANA registered)
Zig = The language Bun is built with
Bun = The fast JS runtime
Claude = Anthropic's AI
## The Problem
AI coding tools have amnesia. Every session starts from zero. You explain your stack, your conventions, your architecture—gone.
## The Solution
A file format that persists. .faf - your project's DNA for any AI.
## I Built Two CLIs
### bun-sticky-faf (TypeScript)
bash
bun add -g bun-sticky-faf
bun-sticky score
Zero deps. 328 tests. Pure Bun APIs.
bun-sticky-zig (Zig)
77KB binary. 31µs scoring. 55 million ops/sec.
Built in Bun's own language. 220X faster than TypeScript.
Why Bun?
Bun's philosophy aligns with FAF: fast, lean, no bloat. Zig (Bun's core language) takes it further—freestanding WASM, no hidden allocations, raw speed.
The Numbers
| Metric | Value |
|----------------|-------------|
| Scoring speed | 31µs |
| Ops/sec | 55 million |
| Binary size | 77KB |
| vs TS baseline | 220X faster |
Why This Stack?
Bun is fast. Zig is faster. Claude needs context. FAF provides it.
The circle completes.
