Agent Skills cover with Spec, Plan, Build, Test, Review, Simplify and Ship workflow labels.
Project screenshotsAbout this Skill
Implement behavior with red-green-refactor and reproduce bugs in failing tests before applying fixes. Discover the repository's language and test runner, write a meaningful failure, implement the smallest fix and refactor with checks.
Why we picked it
A task workflow in Addy's Agent Skills. Follow the upstream instructions and retain referenced shared files; host capabilities and project configuration determine which steps can run.
What it helps with
- Logic is changing or a reported bug needs a reproducible guard.
Workflow and deliverables
Discover the repository's language and test runner, write a meaningful failure, implement the smallest fix and refactor with checks.
Behavior-focused tests, implementation and evidence that the regression test failed before the fix and passed afterward.
Install with the required references
Install the complete pack through a documented repository integration when shared references are needed. A per-skill skills CLI install copies only skills/<name>/ and can omit the repository-level references/ checklists; keep the needed shared files with the workflow.
Before you use it
- An Agent that can load Skill Markdown and access your project. File edits, shell commands, builds and checks depend on the selected workflow and its environment.
- Use your project's own runtimes, dependencies and verification commands. The Skill files provide instructions and do not install those project tools.
- Install the complete pack through a documented repository integration when shared references are needed. A per-skill skills CLI install copies only skills/<name>/ and can omit the repository-level references/ checklists; keep the needed shared files with the workflow.
