claude-qa-skills turns Claude Code into a senior quality engineer and a senior developer on enterprise business software: 119 skills in 19 installable plugins, from a fuzzy user story to a go/no-go decision. Test strategy, unit and mutation testing, exploratory testing, CI insights, DORA metrics, Evidence-Based Management, the checks that matter now that coding agents write the code, and, new in v1.2, 7 developer plugins for .NET, Angular, SQL Server, legacy code, Azure DevOps delivery and secure development.
Why? Agents made writing code cheap; verification became the bottleneck. These skills push Claude to plan before editing, write tests that can actually fail, show evidence before saying "done", and measure delivery instead of activity.
⚡ Install in 30 seconds
/plugin marketplace add RobinBeraud/claude-qa-skills
/plugin install qa-test-strategy@claude-qa-skills
Then just ask: "Review the testability of this story", "Which tests are flaky in these JUnit reports?", "Compute our DORA metrics from this export". Claude picks the right skill, or call one directly: /qa-ai-era:ai-pr-review.

🛠️ New in v1.2: developer plugins
Most popular skill libraries target greenfield web stacks. Business software lives elsewhere: a 15-year-old .NET solution half on .NET Framework, Angular three majors behind, SQL Server, Azure DevOps (sometimes still TFVC), several maintained release branches, multi-tenant SaaS, French accessibility (RGAA) and data-protection (GDPR) rules, pull requests that wait for weeks. The 40 dev-* skills give Claude the habits of a senior developer there.
| Plugin | Highlights |
|---|
dev-workflow | explore before editing, plan in files, root-cause debugging, PR size budget (script), PR description from the diff, self-review, receiving review, worktrees, handoff |
dev-dotnet | solution inventory with support status and package drift (script), .NET Framework to .NET 10, modern C#, xUnit/Testcontainers, EF Core performance and migrations, NuGet |
dev-web | Angular modernisation (standalone, signals, control flow), TypeScript strict step by step, WCAG 2.2 / RGAA 4.1, i18n with decimal commas and no-break spaces |
dev-data | SQL Server plans and Query Store, zero-downtime schema changes, multi-tenant isolation, GDPR by design |
dev-legacy | hotspots and hidden coupling from git history (script), strangler fig, TFVC to Git, fixes missing from release branches (script), dead code |
dev-delivery | Azure Pipelines YAML, AB# linking and WIQL, Conventional Commits and release notes (script), stale PR triage for Azure DevOps, GitHub, GitLab (script), feature flags, incident reviews |
dev-security | secure code review (.NET, Angular), STRIDE, insecure defaults, SBOM and licences, pre-commit secret scanner (script) |
Built after studying the most-starred skill libraries (stars as of November 2026), keeping what makes them work and writing every skill from scratch: one hard rule and a red-flags list per discipline skill (obra/superpowers, 315k), the skill format and scripts for deterministic work (anthropics/skills, 192k), one plugin per domain (wshobson/agents, 42k), plans that live in files (planning-with-files, 28k), stack specialists with checkpoints (Jeffallan/claude-skills, 12k) and security procedures (trailofbits/skills, 8k).
