Done Certificates

Category: General  ·  Sub-category: general-misc  ·  Last updated:
Author a task-specific semi-formal done certificate — a structured verification protocol that a separate validating agent runs to decide whether a task is complete. For each task it restates the definition of done as proof obligations, names the exact evidence to collect and the resolution/regression checks to run, and leaves the status and verdict blank for the validator to discharge. Triggers on "create a done certificate", "add done certificates to the plan", or "generate a completion certificate". Works standalone over any task with a definition of done, and is the companion certificate-author for spec-planner task packages — one certificate per task. To run (discharge) an authored certificate, use validate-done-certificate instead.

From the source SKILL.md

A skill for writing the verification protocol that decides whether a task is done — not for running it. For each task it produces a task-specific semi-formal reasoning certificate: the definition of done restated as explicit proof obligations, each naming the evidence a validator must collect and the checks it must run, with the status and verdict left blank. A separate validating agent later opens the certificate and discharges it against the code.

What this skill does
