Code Review & Quality Agent Plugins
Code Review & Quality is the 7th-largest category in agentpluginsdirectory.com's verified index: 121 of the 2,790 distinct Agent Plugins verified on 2026-09-23, or 4% 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 121, 108 ship at least one Agent Skill and 27 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.

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 skillsRepo-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.
