Code Review & Quality Agent Plugins

Code Review & Quality is the 7th-largest category in agentpluginsdirectory.com's verified index: 112 of the 5,701 distinct Agent Plugins verified on 2026-11-07, or 2% of the directory. It covers plugins that read existing code and judge it: code review, refactoring guidance, linting and static analysis, debugging assistance, performance profiling, and codebase auditing. Of these 112, 100 ship at least one Agent Skill and 24 declare MCP servers.

Analysing or improving code that already exists. Writing new tests for it belongs to Testing; scanning it for vulnerabilities belongs to Security. Agent Plugins 1.0.0 defines no category field, so this grouping is editorial, not read from the manifest — the verification claim covers the plugin, not the category.

  46. verify-catalog-conformance0.0.1Repo-local policy (this repo only, never published): run the fast deterministic catalog checks at commit time, registry labels, README counts, quoted console output, workflow-trigger safety, so a mismatch fails in seconds under the committer's hands instead of minutes later in CI. Each of these caught a real error from CI on 2026-08-16. CI remains the authority: it re-runs the same tools on the pinned engine plus everything too slow for a hook (evals, transcripts, the staged adopter). Skips with a warning when python is absent, because the backstop is what makes that honest.open-coder-ai1 skills3
  47. calm-craft0.4.5Specs as the source of truth, a chunked delivery loop, and decided-and-enforced code conventions, as portable agent skills.calmtechltd36 skills2
