AI-assisted test generation + curation: 3 skills (ai-test-generator, ai-spec-coverage-mapper, model-based-test-graph-author) and 2 agents (ai-test-curator, ai-test-shallow-coverage-critic).
Adversarial reviewer for AI-generated tests - reads the LLM's output and flags hallucinated APIs (functions / classes / imports the LLM invented), weak assertions (`.toBeTruthy()` style), redundancy with existing tests, missing setup/teardown, and naming patterns the LLM defaults to. Refuses to mark generated tests "ready" if any high-confidence issue remains. Use as the required downstream gate for `ai-test-generator` - never merge AI-generated tests without this curator's approval.
Adversarial reviewer that flags tests covering only the happy path - same valid input class, same nominal flow, no boundaries, no error branches, no negative cases. Distinct from `ai-test-curator` (which catches hallucinated APIs and weak assertions) and from `assertion-quality-reviewer` (which catches vague matchers): this agent targets **input-domain coverage** using the ISTQB equivalence-partitioning and boundary-value-analysis techniques. Refuses to clear a test file unless the suite covers at least one boundary case and at least one error/negative case per public entry point. Use as the required downstream gate after any AI-assisted test generation, including `ai-test-generator`, Copilot-suggested tests, and Cursor-authored tests.
Action-taking orchestrator that builds a complete model-based test suite for a stateful SUT in one pass: derives the state/transition graph via model-based-test-graph-author, feeds the validated model to ai-test-generator to produce covering test cases, and emits the assembled suite with a curation note routing to ai-test-curator before merge. Distinct from ai-test-curator (adversarial reviewer only) and model-based-test-graph-author (model authoring only) - this agent is the single entry point for the full MBT pipeline. Use when a mid/senior SDET needs to bootstrap a model-based test suite for a complex stateful flow (checkout, onboarding, multi-step wizard) and wants the graph derivation and test generation done in one coordinated run.
Build-an-X workflow that uses an LLM to map existing tests to spec sections - given a spec doc + the test suite, the LLM identifies which tests cover which sections, surfaces uncovered sections (gap), and recommends specific tests to add. Output is a coverage matrix per spec ID. Use as a follow-up to `ai-test-generator` (which generates tests for new ACs) - this maps the existing landscape and finds what's missing.
Build-an-X workflow that uses an LLM to generate tests from natural-language specs (acceptance criteria, user stories) - outputs tests with confidence scoring per case (LLM's own self-assessment + heuristics: assertion-quality, naming, completeness), batches uncertain cases for human review, integrates with the team's existing test framework. Critical: AI-generated tests are unreliable without curation; pairs with `ai-test-curator` (the adversarial reviewer). Use when a team has many AC to convert and wants AI-augmentation, not AI-replacement.
Build-an-X workflow for model-based testing (MBT) per the canonical definition - authors a state-machine model of the SUT (states + transitions + guards + actions), validates the model is connected and complete, and feeds the model to a test generator (manual / AI / dedicated MBT tool) that produces test paths covering each transition. Per [Wikipedia](https://en.wikipedia.org/wiki/Model-based_testing): MBT "leverages model-based design for designing and possibly executing tests." Use when a complex stateful flow (checkout, onboarding, multi-step wizard) needs systematic coverage that ad-hoc tests miss.

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.
