Stop re-explaining your project every time you switch AI agents.

Dependencies
// Overview
A zero-dependency CLI that maintains a git-diffable .aicontext/ folder in your repo — a compact, token-budgeted map of your codebase and project state. Switch between Claude Code, Codex, Cursor or a fresh session and the agent picks up where the last one left off, without re-reading the whole tree.
// Problem
Every time you switch AI coding agents — or just open a new session — context resets. You burn tokens and time re-explaining architecture the model already figured out an hour ago.
// Approach
01Committed context lives beside the code in .aicontext/, so state is version-controlled and diffable in PRs.
02WASM tree-sitter extraction pulls symbols, routes, components and DB schema — not raw code — for a dense, structured map.
03Token-budgeted output that degrades gracefully as the repo grows; full project context in ~800 tokens.
04Deterministic, byte-stable index.json — same repo state produces the same index, so diffs stay clean.
05Framework-aware extractors for Next.js, Express, React, Prisma and Mongoose.
06Multi-agent task board for coordinating work across tools; optional AI-generated file summaries.
// Outcome
›Zero native dependencies — pure npx fetch, fully offline
›No telemetry, no API keys required
›Full project context in ~800 tokens
›Deterministic byte-stable index for clean git diffs
