qarunbook is an app testing runbook where AI drafts a test plan from your code and your team or AI works through it, tracking issues and retests.

Key features

  • AI-Drafted Test Plans: The /test-checklist skill looks through your app and drafts checks with steps and expected results already filled in.
  • MCP Connection: Connect Claude Code, Claude Desktop, Codex, Cursor or any MCP client so the assistant can read the plan and record results.
  • Issue-to-Check Linking: Every issue sits on the check that found it with the affected platforms, and raising one removes the pass.
  • Retest Flow: When an issue is fixed the check waits for someone to look again before being marked passed.
  • Roles and Join Links: Give people access to only the projects they need and invite whole groups with a join link.
  • Multi-App Workspaces: Keep each app's sections and platforms separate so web, driver and marketing sites are tested side by side.
  • GitHub and Linear Integration: Connect issue trackers so problems found in testing flow into existing engineering workflows.
  • QA Runbook Skill: The /qa-runbook skill works through the plan on web and mobile, recording each result and re-checking fixes.

Best for

  • Release Testing: Run a structured test plan before each release across web, Android and iOS.
  • AI-Assisted QA: Let a coding assistant execute checks and record pass/fail results through MCP.
  • Team Test Coordination: Split test checklists among teammates and see progress and results in one workspace.
  • Regression Follow-up: Track bugs against specific checks and retest them after fixes ship.
  • Solo Developer Testing: Generate a test plan from the codebase so a one-person team knows what to check.
  • Agency Multi-Client QA: Manage separate apps and clients with scoped access and a flat workspace price.
