mypy

mypy is a command for Claude Code from Insight-Services-APAC/ingenious. It costs 0 tokens per session (92 once invoked), scanned A, original, MIT.

A command that runs mypy, a Python tool that checks whether type annotations are used consistently, and asks the agent to fix the reported errors.

In plain words
What is it for?
Use it to check a Python project for type errors, update the code, and rerun the check until the errors are resolved.
Why use it?
It finds type mistakes before they cause runtime problems and provides a repeat-until-clean workflow.

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

mypy 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 yesterday.

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

Find and Fix mypy Errors

  1. Run mypy to check for type errors in your codebase:

    uv run mypy .
    
  2. Review the output for any reported errors.

  3. For each error, update your code to fix the type issue as indicated by mypy.

  4. Re-run the command until no errors are reported.

you can ignore issues with external dependencies by modifying pyproject.toml

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.
