Generate a project-local verification skill that drives your app the way a user does — any language, framework, or platform. Use for /create-verification-skill, "make a control skill for this repo", or when a project has no scripted way to prove UI/CLI/service behavior.
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
# Create a verification skill
Every serious project needs a scripted way to drive the real app and prove behavior: launch it, exercise a feature the way a user would, and capture evidence. This skill generates that as a project-local skill (`.claude/skills/verify-<app>/`) tailored to the repo. You write the generator's output for the next agent, not for a human: it will be read cold, mid-task, by an agent that has never seen the app.
**Platform note.** The generated skill lands under `.claude/skills/verify-<app>/` on Claude Code. On Codex or another runtime, write it to that runtime's project-skill location instead. The app-driving harness (browser/CDP, PTY/tmux, HTTP) is platform-neutral; resolve any tool names via [`codex-tools.md`](../poteto-mode/references/codex-tools.md).
## 1. Interview the repo, not the user
Answer these from the codebase and only ask the user what you cannot observe:
- **Surface:** what does a user actually touch? A web UI, a CLI/TUI, a desktop app, an API, a mobile app, a library? A repo can have several; pick the primary one and note the rest.

The line at the top of this page pins the label git:20261014.daa0fc5, 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.
