Production code quality: 5 skills (sonarqube-quality-perspective, codeclimate-config, lizard-complexity, madge-deps, knip-dead-code) and 1 agent (code-quality-critic). Production-only scope; test-code hygiene is owned by qa-test-review.
Configure Code Climate Quality (now Qlty) for repository-wide quality gates - duplication, complexity, similar-code, exclude_patterns. Covers both legacy `.codeclimate.yml` (Code Climate Velocity / GitHub integration) and the new `.qlty/qlty.toml` per the Qlty platform migration.
Run Knip against a JS/TS project to detect unused files, unused dependencies, unused exports, and unused class/enum members. Scoped to production code; tests are entry-point-aware via Knip's framework plugins.
Run Lizard against production source to enforce per-function cyclomatic complexity (CCN), NLOC, and parameter-count thresholds - language-agnostic (30+ languages). Scoped to production code via `-x"./tests/*"`; test complexity is owned by qa-test-review.
Run Madge against a JS/TS production source tree to detect circular dependencies, find orphan modules, and visualize the module graph. Scoped to production code via `excludeRegExp` for test files.
Run SonarQube/SonarCloud against production code to surface Code Smells, Bugs, and Maintainability ratings - the quality lens (cross-ref qa-sast for the Vulnerability/Hotspot lens). Production-only scope via sonar.exclusions; test code is owned by qa-test-review.

A rigorously curated quality-engineering plugin marketplace for Claude Code. 77 plugins, 695 components, every one rating-gated before merge.
d6 floordocs/REVIEWER_TRAINING.mdSee Quality bar and docs/REVIEWER_CHECKLIST.md.
The marketplace ships three kinds of building block:
qa-api-testing, qa-load-testing). You install only the plugins your
stack needs.great-expectations,
oauth-flow-test-author). Claude loads a skill when your request matches
its trigger; you can also ask for it by name.schema-diff-reviewer reviews a migration diff and returns a findings
table). An agent may preload one or more skills to do its work.Installed components stay dormant until a matching task comes up, so adding a plugin doesn't add noise — it adds capability that activates on demand.
/plugin marketplace add testland/qa
/plugin install <plugin-name>@testland-qa
For example:
/plugin install qa-data-quality@testland-qa
/plugin marketplace add https://github.com/testland/qa
git clone https://github.com/testland/qa ~/.claude/marketplaces/testland-qa
Before you install: plugins run inside your Claude Code session and ship agent instructions and tool wrappers. Anthropic doesn't vet marketplace contents — review a plugin's components before installing it into a sensitive project. Every component here is rating-gated (see Quality bar), but you remain in control of what runs.
New to the marketplace? Install one or two plugins for your role rather than everything — components activate on demand, so a focused set keeps things sharp.

Once a plugin is installed, its skills and agents are available to Claude
Code — invoke them by describing the task in plain language. Example with
qa-data-quality:
/plugin install qa-data-quality@testland-qa
great-expectations skill scaffolds an ExpectationSuite + Checkpoint and
wires the results into a CI gate.schema-diff-reviewer agent returns a Critical / Warning / Info findings
table covering breaking-vs-additive changes and downstream impact.Each plugin's README.md lists its skills and agents and what each one does.
