Checkpoint 3 bridge that turns ACs into Gherkin specs and hands off to the ATDD acceptance pipeline workflow.
EnglishUse when the user asks to "run mutation testing", "mutate my code", "kill mutants", "check test quality", "find surviving mutants", "verify test effectiveness with mutations", "run stryker", "run mutmut", "run pitest", "set up mutation testing", "how good are my tests", "are my tests catching bugs", or mentions mutation testing, mutation score, or mutant survival in the context of testing. It adds a third validation layer to the ATDD workflow: after acceptance tests verify WHAT and unit tests verify HOW, mutation testing verifies that tests actually catch bugs.
EnglishUse when the user asks to "build a feature with a team", "use ATDD with agents", "create an ATDD team", "set up a team for ATDD", "orchestrate agents for ATDD", "use team-based development", "coordinate agents for feature development", "run the ATDD workflow with teammates", "add ATDD to my team", "extend my team with ATDD", "join the team with ATDD agents", "add spec-writer and reviewer to the team", or "add ATDD roles to the existing team". It orchestrates a six-phase ATDD workflow — spec writing, spec review, pipeline generation, implementation, refine, verify & harden — spawning a fresh agent per phase so no agent erodes across a long-running feature.
EnglishAnalyze changed code for complex, under-tested functions using CRAP scoring; produce ranked refactor and test recommendations.
EnglishUse when a Ready feature needs its acceptance criteria discovered before specs are written. Triggers — "engineer plugin -> discover-acs skill", "engineer plugin -> acceptance-criteria skill", "discover ACs", "what must this feature do", "figure out acceptance criteria".
EnglishAnalyze surviving mutants from a mutation testing run and write targeted unit tests to kill them. Re-runs mutations to confirm kills.
EnglishUse to propagate DAE state — turning handoff summaries into visible progress. Triggers — "engineer plugin -> progress-log skill", "sync progress", "update the tracker", "reconcile the tracker", "refresh feature status".
EnglishRe-anchor an in-flight DAE feature after compaction, interruption, or uncertainty about checkpoint and next action.

Quick start
- Choose your skills. Select individual skills above, or choose the entire pack.
- Copy the install prompt. Use Copy install prompt above the list.
- Send it to your agent. Paste into your coding agent’s chat. Your agent reviews the source and guides the setup.
Try it with your agent
After installation, start with a request like:
Use the Atdd skill to help with my task.
Ask me for the context you need before getting started.Requirements & license
- A coding agent that can access your project files and install skills.
- Your agent checks each skill’s instructions, dependencies, and permissions during setup.
- Reported license for the skills shown: MIT. The author’s terms apply.
