Mirror the HTTP requests that AI coding CLIs (OpenCode / Claude Code / Codex) send to model providers into a local viewer, so you can inspect the full request context — headers, system prompt, tool definitions, messages — and (optionally) the model's response.

Architecture

Claude Code ──ANTHROPIC_BASE_URL──▶ ┐
Codex CLI  ──config.toml base_url─▶ ├─▶ proxy ──HTTPS──▶ AI API
OpenCode   ──opencode.json baseURL▶ ┘      │
                                            └──POST──▶ viewer (:39877)

The proxy forwards traffic untouched to the upstream API and mirrors a copy of each request to the viewer — a fire-and-forget side channel that never blocks or alters the main request/response path. One proxy port can route to multiple upstreams by path prefix; the viewer classifies entries by source and API protocol.

Install

Requires Node.js >= 18. Zero runtime dependencies.

Global install (recommended):

npm install -g context-tracker
# or from source: git clone https://github.com/conrad621/context-tracker.git && cd context-tracker && npm link

This provides a single `context-tracker` command:

context-tracker start           # start the viewer AND the proxy together (one process)
context-tracker help            # show usage

Without installing you can run the scripts directly: `node src/start.js`. The viewer and proxy still live at `src/viewer.js` / `src/proxy.js` for advanced use, but the CLI exposes only `start`.
