Engine for context-bar: AI coding-agent usage, rolling quota windows, and API-equivalent cost estimation from local transcripts.
Documentation

context-bar-core — the cross-platform engine.

Everything reusable across the surfaces lives here: transcript reading, the cost/token model, session/window bucketing, the agent-context assembler, and the HUD/HTML renderers. The crate is platform-free at the type/parse/assemble layer; the host-coupled bits (process spawning, the macOS keychain, the on-disk snapshot cache, and the wasm32 Worktree collectors) sit behind cfg(target_arch) gates inside their modules.

Consumers:

  • the context-bar CLI/menubar engine (native) calls [usage_signal::collect_native], [context_engine::assemble], [state_writer::write], [hud::render], [detail_html::render];
  • the Zed extension (wasm32) reuses the same types and calls the Worktree-backed collectors (git_signal::collect, usage_signal::collect, context_engine::ContextEngine::generate).

The seam that keeps the engine decoupled from any host is [context_engine::assemble], which takes pre-collected signals.
