Use this skill to turn a broad "test every feature in this app" request into a controlled loop with one source of truth. Anchor every feature to code, track expected behavior in a canonical spreadsheet, run tests against each user story, and classify failures. Apply fixes only when the current request explicitly authorizes them.
Use plan_first for most runs. Switch to clarify_first only when the app boundary, writable checkout, production risk, or acceptance criteria are unclear enough that a wrong assumption would waste substantial work.
Before editing:
AGENTS.md, README, architecture docs, and feature entrypoints.Select one mode before editing production code:
report_only is the default for audit, inventory, test, diagnose, or tracker requests. It may create or update the requested canonical tracker and run tests, but it must not change product behavior.apply_fixes requires the current user request to explicitly ask for fixes. It covers only defects already reproduced and classified within the agreed app boundary. Earlier approval and a generic request to "test everything" do not authorize fixes.If the mode is ambiguous, use report_only and record proposed fixes in the tracker.
Direct actions:
apply_fixes only, fix narrow in-scope logistical or UX defects and add focused coverage when user-observable behavior changes.Escalate before:
Evidence-backed pushback:
Feedback loop:
Automatically, when a task matches. Use when the user asks to audit every feature, derive expected behavior from code, test user journeys, or explicitly fix and retest documented UX or logistical defects.
