Builds and maintains a repo's own verification harness (verify CLI, doctor, worktree isolation, feature map, seed data) and a reproduce-first bug handoff. Use when asked to "build a verification harness", "add a doctor command", "prove every feature still works", or "reproduce this bug report".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# App Verification Builds, inside a product's own repository, the harness every agent uses to run that product and prove a claim about it: a verify CLI, a doctor command, an isolated instance per worktree, a feature map written from the user's point of view, seed data and test accounts, and a reproduce-first bug handoff. The harness lives in the target repo, not in this skill; this skill scaffolds and then maintains it, so every agent that opens that repo runs the app the same way instead of writing a throwaway script each session. - **IS:** scaffolding a project-local verification harness (Create mode) and running or extending one that already exists (Maintain mode): the verify CLI's contract, the feature-map format, the proof record, per-worktree isolation and seed data, the cheapest-method ladder up to computer use, and the bug-handoff format. …

How to install
mdr add mblode/agent-skills/app-verification@sha256:b71bd21ab8826925The line at the top of this page pins the label git:20261016.81d0af2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
