Security: a SAST tool (e.g., Bandit).</li>\n<li>Testing: <code>pytest</code> with function-based tests, <code>pytest-cov</code> (80%+), <code>hypothesis</code> for property-based.</li>\n<li>Error handling: specific exceptions only, never bare <code>except:</code>, <code>contextlib.suppress</code> for intentional ignoring.</li>\n<li>Dataclasses or Pydantic for structured data — avoid raw dicts for known schemas.</li>\n<li><code>pathlib.Path</code> over <code>os.path</code> for filesystem operations. Google-style docstrings on public APIs.</li>\n<li>Async: <code>async</code>/<code>await</code> for I/O, never mix blocking and async, <code>asyncio.gather()</code> for concurrency.</li>\n<li>Package management: a fast, lockfile-based package manager (e.g., uv) with the lockfile committed, build with a PEP 517 backend (e.g., maturin or hatchling).</li>\n<li>Security: <code>pip-audit</code> for dependency CVE scanning. Zero tolerance for critical/high vulnerabilities.</li>\n<li>Logging: structured logging (key=value / JSON) — never f-strings in log calls.</li>\n<li>Pattern matching (<code>match</code>/<code>case</code>) for multi-branch type dispatch (3.10+).</li>\n<li>Anti-patterns: mutable default args, <code>import *</code>, global state, <code>time.sleep</code> in async.</li>\n</ul>\n","files":[{"path":"SKILL.md","sizeBytes":1531,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
