Try to break a change the way the real world will - network faults, restarts, two things at once, users doing things out of order…
One-time setup for /verify and /break. Sniffs the repo, confirms boot/seed/health with you, writes .verify/setup.json, captures auth if the app needs login, and builds .verify/profile.json, a model of how the app runs.

Run once per repo. Later `/verify` runs read `.verify/setup.json` and ask nothing.
**Hard rule: never ask for or store passwords, API keys, or connection strings.** The one exception is captured browser session state (`.verify/auth.json`, written by the auth step below): it holds reusable cookies for the app under test, is gitignored, and deleting the file revokes it. Treat it like a logged-in browser profile, not a secret store. No production connection strings, no cloud keys. The most this file may reference is one of the repo's own local `.env` files, chosen by the user. If a user pastes a secret, refuse to write it and tell them to keep it in their environment.

`.verify/setup.json` is the one file meant to be shared. After writing it, offer: "Commit `.verify/setup.json` so your team skips this interview? (y/n)" — on yes, `git add -f .verify/setup.json` and commit it.
The contract must work in every checkout and worktree of the repo, or the interview repeats forever. Two rules:
documents per-worktree port variables (an AGENTS.md export block, a `.env.example`), write `http://localhost:${INGESTION_PORT:-8082}` — the repo's own variable name with the repo's default — never the number the current worktree happens to use. URL fields (`base_url`, `health_url`) support exactly `${VAR}` and `${VAR:-default}` — no nesting, no command substitution — expanded identically by the scripts and the engine at run time. Probes and boot are shell programs and expand everything the shell does, for free.
(`verify-20260901-042757-worker-1`) is dead the moment that run ends. Key probes to the compose service via the current run's project instead:
docker ps --filter "label=com.docker.compose.project=$(jq -r .project .verify/run-env.json)" \
--filter "label=com.docker.compose.service=worker" --format '{{.State}}' | grep -q runningBefore offering the commit, re-read the drafted contract and reject your own draft if any field contains a resolved port number that has a documented variable, or any name containing a run id.

cat /tmp/verify-sniff.jsonUse AskUserQuestion. Every option must come from the sniff output; the user corrects rather than authors. A single unambiguous candidate is taken silently and shown in the final summary.
"it's already running (breaks isolation — not recommended)" which selects `"mode": "external"`. **The chosen candidate's `mode` and `compose_file` are copied into the contract — never mix a process boot with a compose teardown.** For `"process"` mode, `health_url` is required — do not write the contract until the user supplies the URL to poll. For `"compose"` mode, write `teardown: "docker compose -f <file> down -v"` — a throwaway stack that keeps its volumes is not throwaway.
(if chosen, ask for the path and put it in `seed_data_files`; it is a plain file the user produced themselves — how they made it is outside verify).

var — name the header (for example, `X-API-Key`) and the env var name; or B) no auth. The value itself is never written anywhere: the contract stores only the header name and the env var name.
command that proves your <part> is alive? (leave blank to skip)". Explain: a part with no probe still runs its criteria, but a failure on it will be reported as possibly environmental rather than blamed on the change. (`api`, `browser`, and `db` have built-in probes; don't ask about them.)
If `.has_stack` is false: plain-command mode. Write the contract with `"mode": "none"` and empty boot/teardown/health, and say: "No runnable stack found; /verify will run criteria as plain commands."
Write `.verify/setup.json`. The shape (this example is load-bearing — a test parses it):
{
"mode": "compose",
"compose_file": "compose.yaml",
"boot": "docker compose -f compose.yaml up -d --wait",
"teardown": "docker compose -f compose.yaml down -v",
"seed": ["scripts/seed-e2e.sql"],
"seed_data_files": [],
"health_url": "",
"base_url": "http://localhost:${APP_PORT:-3000}",
"auth": {"header": "", "value_env": ""},
"env_file": ".env.example",
"observe": {"db_url_env": "DATABASE_URL"},
"probes": {"worker": "", "sink": "", "storage": ""}
}Valid modes: `"compose"`, `"process"` (health_url required), `"external"`, `"none"`.
Show the written file and the summary of silently-taken single candidates.
Keep authentication as Playwright storage state. It contains no password entry flow or credential capture by Verify; the user logs in directly in the browser.
Check whether the selected base URL is running:
VERIFY_
Don't trust your agent. Verify it. Coding agents write more code than anyone can read, and reviewing the diff does not run it. So the agent says done and the tests are green, and both of those came from the agent.
