Discover plugins that extend Claude Code with new commands, skills, and workflows.
/plugin marketplace add clauderegistry/marketplaceGets an unfamiliar repo running locally by diagnosing and fixing broken setup, decodes opaque build systems, and does task-scoped change localization and end-to-end flow tracing, so you're productive on day one
A repo-native toolchain for LLM apps: scaffolds eval suites, red-teams for prompt injection, hardens structured-output reliability, and audits token cost, riding promptfoo/DeepEval/Pydantic rather than replacing them
Keeps your API and its spec in sync: detects and fixes OpenAPI/GraphQL spec-vs-code drift, hardens endpoints with request validation, RFC 9457 error envelopes and idempotency, guards against breaking changes, and audits job-queue reliability
Goes past detecting accessibility and localization issues to fixing them: cross-element ARIA and keyboard-focus remediation, color-contrast rewrites, hardcoded-string extraction, ICU MessageFormat correctness, and RTL readiness
Static, no-database-connection guardrails for schema and query work: rewrites unsafe migrations into zero-downtime expand-contract steps, hunts ORM N+1 queries in your diff, interprets pasted EXPLAIN plans, and flags schema anti-patterns
Triages failing GitHub Actions runs, hardens Dockerfiles, pre-flights Kubernetes manifests before they reach the cluster, and drafts blameless postmortems from incident evidence
Owns everything around the diff: craft Conventional Commits and PR descriptions, recommend the right semver bump by reasoning about behavioral breaking changes, assemble changelogs from messy history, and guide merge-conflict resolution, rebase planning, and git-history archaeology
