- description:
- Use when a plan needs verification checkpoints to measure whether completed work meets requirements and quality standards. Called by the plan skill — not invoked directly by users.
- model:
- opus
- user-invocable:
- false
- context:
- fork
Define verification checkpoints that measure whether the implementation meets requirements, and save to checklist.md.
Input
- The exploration at
.powerball/specs/YYYY-MM-DD-{{name}}/exploration.md - The plan at
.powerball/specs/YYYY-MM-DD-{{name}}/plan.md— read the goal and architecture decisions from here
To find the directory, search .powerball/specs/ for a directory ending with -{{name}}.
Important: Do NOT read tasks.md. This skill runs in parallel with writing-tasks — both read from exploration.md and plan.md independently. The checklist must think about observable outcomes, not mirror implementation steps.
Process
- Review the goal, and architecture to identify what "done" looks like.
- Write checkpoints that are verifiable — each should have a clear pass/fail answer.
- Categorize checkpoints by type:
- Functional — does the feature work as intended?
- Quality — does the code meet standards (tests, types, no warnings)?
- Integration — does it work with existing systems without breaking them?
- Security — are there no exposed secrets, injection risks, or auth gaps?
- Order from most critical to least critical within each category.
Output
- Read the template from this skill's
templates/checklist.md - Fill in the template — replace
{{NAME}},{{DATE}}, and all placeholders with actual content - Write to
.powerball/specs/YYYY-MM-DD-{{name}}/checklist.md
Guidelines
- Every checkpoint must be answerable with yes/no — avoid subjective criteria
- Checkpoints verify observable outcomes, not individual implementation steps — e.g., "clicking the button triggers action X and log Y is visible" rather than "button text changed" + "onClick handler added", or "API returns 200" rather than "API was tested"
- Think about what the user or system would experience when the work is complete, not what the developer did
- A single checkpoint can (and should) verify the combined result of multiple implementation steps
- If a checkpoint can't be verified without manual testing, note how to verify it
