claudeloop / rules

adammatthewsteinberger/claudeloop/.cursor/rules/claudeloop-quality-gates.mdc

Covers how to run and FIX every quality gate in this repo — ruff (lint + format), mypy --strict, pytest with per-layer coverage, import-linter (lint-imports), bandit, and pip-audit. Use this whenever a quality gate fails locally or in CI, whenever the user asks how to lint, format, type-check, or run security scans on this codebase, or before opening a PR to run the full gate set proactively. Make sure to consult this whenever a ruff, mypy, lint-imports, or bandit error appears in tool output — it gives the exact fix command for each gate rather than requiring you to guess at generic remediation.
