Generate a project-local verification skill that drives your app the way a user does — any language, framework, or platform.

On Codex, read the platform mapping, including its per-skill notes, before following this 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/) tailored to the repo. Name it verify. At the repo root a project skill by that name replaces Claude Code's bundled /verify, which only the user can invoke, so every playbook that names the driver skill can call the project one (Claude Code 2.1.200 or later). In a monorepo, write it in the touched package directory instead. 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.
Answer these from the codebase and only ask the user what you cannot observe:
If the checkout doesn't build or start as-is, fix that first (or report it precisely) before generating; a skill written against a broken base teaches wrong steps. When an irrelevant missing asset blocks startup (a static dir the API never serves, a sample config), the generated skill may create it, clearly marked as verification scaffolding, and remove it in cleanup.
Write .claude/skills/verify/SKILL.md with YAML frontmatter (name: verify and a description that names the app, the surface, and when to reach for it — without frontmatter the skill never registers, and with disable-model-invocation the model cannot call it) and these sections, each grounded in what the interview actually found (no placeholders left):
Create .claude/skills/verify/features/README.md plus one file per user-facing feature you can identify (aim for the top 3-5 to start, from routes, commands, menus, or docs). Follow the shape in references/feature-map-example/, with a README index and one file per feature. Each file answers, from the user's point of view: what the feature is, how to reach it, how to drive it with the harness, and what observable end state proves it works. The four H2s are Sub-features, How to get to it (user POV), Driving it with <harness>, and Gotchas. The map is the repo's maintained verification source; a proof that drives one convenient entry point is incomplete when the map lists others.
Run its own instructions end to end once: launch, doctor, drive ONE mapped feature (one is enough; the map exists so later runs can cover the rest), capture evidence, clean up. After cleanup, confirm the evidence still exists at the named location — a cleanup that eats the proof fails this step. Fix what fails, and run the generated cleanup after every failed iteration too, so broken attempts don't strand processes and ports. A generated skill that was never executed is a draft, not a deliverable.
Point the user at /maintain-verification-skill for keeping the map honest as the app changes. Suggest a cadence only if they ask.

Use for /create-verification-skill, \"make a control skill for this repo\", \"make a driver skill for this repo\", or when a project has no scripted way to prove UI/CLI/service behavior." --- # Create a verification skill On Codex, read the [platform mapping](../poteto-mode/references/codex-tools.md), including its per-skill notes, before following this 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/`) tailored to the repo. Name it `verify`. At the repo root a project skill by that name replaces Claude Code's bundled `/verify`, which only the user can invoke, so every playbook that names the driver skill can call the project one ([Claude Code 2.1.200 or later](https://code.claude.com/docs/en/skills#run-and-verify-your-app)). In a monorepo, write it in the touched package directory instead. 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. ## 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. - **Run:** how does the app start locally? Prefer the repo's own documented dev command (package scripts, Makefile, README quickstart). Note ports, env vars, seed data, auth. - **Drive:** how can an agent interact with it programmatically? Existing harnesses first — Playwright/Cypress specs, expect scripts, PTY helpers, curl-able endpoints, a debug port. Only then pick a generic recipe: browser/CDP for web and Electron, a tmux/PTY harness for CLI/TUI, plain HTTP for services. - **Observe:** what evidence can be captured? Screenshots, terminal transcripts, response bodies, logs, exit codes, DB state. - **Isolate:** can two instances run side by side (ports, data dirs, profiles)? If not, say so in the generated skill: refusing to double-drive a shared instance beats corrupting the user's session. If the checkout doesn't build or start as-is, fix that first (or report it precisely) before generating; a skill written against a broken base teaches wrong steps. When an irrelevant missing asset blocks startup (a static dir the API never serves, a sample config), the generated skill may create it, clearly marked as verification scaffolding, and remove it in cleanup. ## 2. Generate the skill Write `.claude/skills/verify/SKILL.md` with YAML frontmatter (`name: verify` and a `description` that names the app, the surface, and when to reach for it — without frontmatter the skill never registers, and with `disable-model-invocation` the model cannot call it) and these sections, each grounded in what the interview actually found (no placeholders left): - **Launch:** the exact command that starts the app for verification, and how to tell it's ready (a log line, a port answering, a prompt). Include teardown. For a short-lived CLI or TUI there is no server to keep alive: launch means build the binary (or install deps) once, then start each drive in its own isolated PTY or tmux session. - **Doctor:** one read-only check that answers "is this instance worth driving?" — process up, right version/build, port owned by us, auth valid. An agent runs this first whenever anything looks off. - **Drive:** the harness recipe with real selectors/commands from this repo, not examples. Prefer stable handles (ARIA labels, data attributes, prompt strings, route paths) over coordinates and tab order. - **Evidence:** what to capture for a proof and where it goes. State the proof standards: exercise the real user path, not internal setters or test-only endpoints; capture the action and the resulting state, not just the final screen; verify side effects (files written, rows inserted, messages sent) alongside what's visible; mocks only where a production boundary already isolates the external system. When the safe path is a dry-run or test mode, verify what it actually skips by observing (files, network, git refs) rather than trusting its name: some dry-runs still touch the network or open a browser. - **Cleanup:** how to tear down instances the run created. Never kill by process name; kill what you started. Cleanup removes instances and scratch state, never the evidence: proof artifacts survive the teardown, in a location the skill names. - **Helpers:** any script the skill ships is executable and its invocation is shown in the skill body. A helper the reader has to reverse-engineer is not a helper. ## 3. Seed the feature map Create `.claude/skills/verify/features/README.md` plus one file per user-facing feature you can identify (aim for the top 3-5 to start, from routes, commands, menus, or docs). Follow the shape in [`references/feature-map-example/`](references/feature-map-example/), with a README index and one file per feature. Each file answers, from the user's point of view: what the feature is, how to reach it, how to drive it with the harness, and what observable end state proves it works. The four H2s are `Sub-features`, `How to get to it (user POV)`, `Driving it with <harness>`, and `Gotchas`. The map is the repo's maintained verification source; a proof that drives one convenient entry point is incomplete when the map lists others. ## 4. Prove the generated skill before handing it over Run its own instructions end to end once: launch, doctor, drive ONE mapped feature (one is enough; the map exists so later runs can cover the rest), capture evidence, clean up. After cleanup, confirm the evidence still exists at the named location — a cleanup that eats the proof fails this step. Fix what fails, and run the generated cleanup after every failed iteration too, so broken attempts don't strand processes and ports. A generated skill that was never executed is a draft, not a deliverable. ## 5. Offer the maintenance loop Point the user at `/maintain-verification-skill` for keeping the map honest as the app changes. Suggest a cadence only if they ask.
