testland-qa
A rigorously curated quality-engineering plugin marketplace for Claude Code.
77 plugins, 695 components, every one rating-gated before merge.
Why testland-qa
- 6-dimension quality rubric (D1–D6) before merge, with a hard-reject for
uncited claims (citation theater) via the
d6 floor
- CI-validated composition: every agent's preloaded skills are
reference-checked, no dangling deps
- Differentiation required: every component must articulate how it
differs from its nearest neighbors. Generic, persona-shaped scopes that
can't name a trigger condition get sent back for reshaping
- Reviewer-calibrated: two-evaluator rubric, A/C/F-grade exemplars in
docs/REVIEWER_TRAINING.md
See Quality bar and docs/REVIEWER_CHECKLIST.md.
How it works
The marketplace ships three kinds of building block:
- Plugin — an installable bundle scoped to one QA area (e.g.
qa-api-testing, qa-load-testing). You install only the plugins your
stack needs.
- Skill — an atomic, self-contained capability inside a plugin, usually
wrapping one tool or one technique (e.g.
great-expectations,
oauth-flow-test-author). Claude loads a skill when your request matches
its trigger; you can also ask for it by name.
- Agent — a task-scoped subagent that runs one focused job (e.g.
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.
Install
Claude Code marketplace (recommended)
/plugin marketplace add testland/qa
/plugin install <plugin-name>@testland-qa
For example:
/plugin install qa-data-quality@testland-qa
Direct URL
/plugin marketplace add https://github.com/testland/qa
Manual / hermetic environments
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.
Start here
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.

CATALOG.md.
Using an installed plugin
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
- Ask "add Great Expectations checks to my orders pipeline" → the
great-expectations skill scaffolds an ExpectationSuite + Checkpoint and
wires the results into a CI gate.
- On a database change, ask "review this migration's schema diff" → the
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.
