lint-and-validate

Quick Review

Strong skill with clear procedures for linting and validation across Python and Node.js ecosystems. The description adequately conveys when to invoke the skill (after code changes, with specific keywords). Task knowledge is comprehensive with concrete commands for multiple tools (eslint, tsc, ruff, mypy, bandit) and a clear quality loop workflow. Structure is good with a concise overview and reference to helper scripts, though the SKILL.md could benefit from slightly more organization of the ecosystem-specific sections. Novelty is moderate—while linting coordination across ecosystems and enforcing a quality loop adds value, the underlying commands are standard developer tools that a CLI agent could invoke directly, though this skill does provide helpful orchestration and enforcement patterns that reduce the cognitive load of remembering all the specific commands and flags.
