Codex Usage Tracker

Codex Usage Tracker is a fast, local-first data kernel for exact Codex usage facts and evidence. Version 0.27 adds compact guided exploration and optional, owner-only context composition to the 0.26 incremental kernel while preserving bounded queries, exact evidence timelines, the six-tool MCP surface, and the focused Evidence Console.

  • Product roadmap: docs/roadmap/product-kernel-reset.md
  • Execution ledger: docs/roadmap/product-kernel-reset-execution.md
  • Active search policy: docs/kernel-development-scope.md
  • Optional context composition: docs/kernel-context-composition.md
  • Read-only overlay adapter contract: docs/kernel-overlay-adapter-contract.md
  • Frozen code disposition: config/kernel-code-disposition-v1.json
  • Frozen retired surfaces: config/kernel-retired-surfaces-v1.json

Run the repository verification gate with:

python3 -m venv .venv
.venv/bin/python -m pip install -e ".[dev]"
just v

The previous 0.25.1 implementation remains available at the immutable v0.25.1 tag. Do not restore retired analysis, telemetry, compatibility, or static-dashboard runtime modules into the active tree.

Install

Install the Python runtime into an isolated executable environment, then add the same tagged repository as a Codex plugin marketplace:

pipx install "codex-usage-tracking==0.27.0"
codex plugin marketplace add douglasmonsky/codex-usage-tracker --ref v0.27.0
codex plugin add codex-usage-tracker@codex-usage-tracker

The plugin launches the codex-usage-tracker executable, so the MCP process uses the exact interpreter owned by the pipx installation. After install, start a fresh Codex task so its tool catalog is discovered from the new plugin bundle.
