pre-commit

A command checklist that runs the same code-quality checks as the project's GitHub CI system. CI is the automated process that checks code on the server after changes are submitted.

In plain words
What is it for?
Use it before committing changes to run linting, mypy type checks, unit tests, and integration tests for the agent and command-line libraries.
Why use it?
It catches style errors, type errors, and failing tests locally before a commit reaches the shared project.

Command for Claude Code

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 18 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 391 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

pre-commit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Pre-Commit Check

Run all CI checks locally before committing. This matches the GitHub CI workflow exactly.

Your Task

Run these checks in order, stopping if any fail:

1. Lint (ruff check)

uv run ruff check libs/ptc-agent/ptc_agent/ libs/ptc-agent/tests/
uv run ruff check libs/ptc-cli/ptc_cli/ libs/ptc-cli/tests/

If there are auto-fixable issues, fix them:

uv run ruff check libs/ptc-agent/ptc_agent/ libs/ptc-agent/tests/ --fix
uv run ruff check libs/ptc-cli/ptc_cli/ libs/ptc-cli/tests/ --fix

2. Type Check (mypy)

cd libs/ptc-agent && uv run mypy ptc_agent/
cd libs/ptc-cli && uv run mypy ptc_cli/

3. Unit Tests

uv run pytest libs/ptc-agent/tests/unit_tests/ -v
uv run pytest libs/ptc-cli/tests/unit_tests/ -v

4. Integration Tests

uv run pytest libs/ptc-agent/tests/integration_tests/ -v
uv run pytest libs/ptc-cli/tests/integration_tests/ -v

Note: Integration tests require DAYTONA_API_KEY and ANTHROPIC_API_KEY environment variables.

Summary

Report results for each step:

  • Lint: PASS/FAIL
  • Type check: PASS/FAIL
  • Unit tests: PASS/FAIL
  • Integration tests: PASS/FAIL/SKIPPED (if env vars missing)
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

pre-commit is a command published in the GitHub repository Chen-zexi/open-ptc-agent (730 stars, last pushed 7mo ago), licensed MIT. It adds 18 tokens to every session and 391 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
