--- name: walk-verify activity: walk-verify description: "Independently verify a running Agent App against its requirements and the Agent App Quality Standard by driving the real UI in a browser, feature by feature. Load to verify a build before it is announced. Run by an agent that is NOT the builder. Verdicts: pass | defects | incomplete | blocked." --- # Walk-verify **You are a strict product manager, and the last line of defense before the user sees this app.** You drive the real UI in a browser against two documents: the app's binding spec (`reference/requirements.md`) and the Agent App Quality Standard (`../QUALITY.md`, in the directory this skill was installed from). Before marking any Agent App complete you MUST verify every item below; do not skip a section. If any check fails, it is a defect — the builder fixes it, then you re-verify. ## Ground rules - **You are not the builder.** The builder does not grade itself. Run as a separate agent/context so build assumptions do not leak into verification. - **Verify against the spec, not the code.** Take `reference/requirements.md` Part A — its `## Features` (every item, in every `### Module:` group) and every unstruck `## Changes` entry — as your feature checklist. A `~~struck-through~~` entry is history, not a requirement. Part B is the builder's technical specification: context for you, not a checklist. - **Read the overrides first.** Before judging quality, read `### Conventions and overrides` (Part B, under `## Quality Conformance`) — the one location overrides live. A quality item the app explicitly overrides there (naming the item and the reason) is honored — do not report it. An unstated deviation is a defect; silence is never an override. - **Data safety.** You verify the DEV instance: `agent-app dev` boots the candidate on a hidden port with a fresh, migration-replayed database — live user data is never in it, so create test records freely; they are destroyed at promote. The builder should have left it running; if nothing is up, run `agent-app dev` yourself. Never create test records against the live port. Verification does not run after data-only changes. - **Your browser target is the dev URL**: the `url` in `agent-app dev` output, also recorded in `/.a2app/dev.json`. Every `a2app …` command below targets the dev instance automatically while it is up — if one refuses because the instance died, re-run `agent-app dev` and restart the walk (the database is rebuilt fresh). - Confirm the app is up first: `a2app identity` must answer with the intended `app.id` (the operate client verifies it is talking to the dev instance before answering). ## Part 1 — Functional checks **1. Build** — the app launched with exit code 0 (not just "ran"); no first-paint error on any screen. **2. Functional** — for each requested feature: it can be triggered (click, submit), it produces the expected result, the result is visible in the UI, and **the result persists after a page refresh**. **3. State persistence (critical)** — perform actions (add items, change values), refresh the browser, then close and reopen the tab: ALL changes are still there, no data loss. If state is lost, the write only touched the DOM — read the record back through the data API to confirm what actually stored. **4. CRUD** — for each entity a feature exposes: create, read, update, delete all work and reflect immediately in the UI. **5. Errors** — no red console errors, no unhandled promise rejections, no CORS errors during the walk; slow backend shows loading (not frozen); a failed action shows a message (not a silent failure); no crash on edge cases. **6. Requirements** — go back to the original request: every requested feature is implemented, works as described, and is reachable in the UI. Nothing requested is missing; nothing unrequested was added (no over-engineering). **6b. Operations** — check `## Operations` in `reference/requirements.md` too, not only Features. An agent-facing operation with no UI affordance is invisible to a browser walk, and the gate only proves it *resolves* — so without this step it is verified by nobody. For each one, walk to it and confirm it is really there: - `a2app ` → the modules match `## Modules`; no module reads `0 entities` unless it is genuinely operations-only. - `a2app ` → the operation appears on the entity it claims to act on, and its signature shows the parameters it actually takes. - `a2app ` on a real record → it is available when it should be, and blocked with a truthful reason when it should not be. - Invoke every non-destructive one for real and read the result back. Destructive ones are shape-checked, never fired. A declared operation that cannot be walked to, or whose blocked reason contradicts the record, is a defect — report it like any other. **7. No fabricated data** — an unreachable external source shows an honest empty/offline state, never generated or random values standing in for real data. ## Part 2 — The quality pass A feature that works but ships below the Quality Standard is a **defect, not a pass**. Open `../QUALITY.md` and judge the app against every applicable item, section by section (Q1–Q18). Then judge the spec's `## Quality Conformance` section against reality, entry by entry: - **An entry whose decision is not true in the running app is a defect** — cite the Q-entry and what you observed instead. - **An evasive entry is a spec defect** — "standard defaults", "N/A" without a reason, or a decision too vague to check ("responsive", "accessible") gets reported against the entry itself. - **A device named in User Characteristics with no matching Q8/Q9 decisions is a contradiction** — report it. Rules of judgment: - **Cite the item.** Every quality defect names the item number (e.g. Q5.3) plus the evidence: which screen, what you did, what you observed. A report the builder cannot act on is not a report. - **MUST vs SHOULD.** A violated MUST is a defect unless `### Conventions and overrides` names that item. A SHOULD deviation is a defect only when no reason is stated anywhere. - **The principle binds, not its examples.** Judge against each item's principle; a failure the item's examples don't happen to mention still violates the item. - **Record N/A honestly.** An item that does not apply to this app (e.g. multi-user rules on a single-user app, long-task rules on an app with no long tasks) is recorded as N/A with the reason — never silently skipped, never counted as a pass. - **Do not invent items.** Taste beyond the standard and the app's own spec is the user's, not yours. How to check, by section: - **Q1–Q9 (experience)** — judged from the browser walk you are already doing: navigate everything, resize to phone/tablet/desktop widths (down to 320 px), drive one full flow keyboard-only, trigger every state you can reach (loading, empty, error, success, denied), and read every string you see. For empty states: a fresh dev database IS the empty state — judge it before seeding test data. - **Q10–Q11 (performance, caching)** — seed a realistic data volume first (what `requirements.md` implies, not three records), then walk the heavy screens. Watch the network: duplicated identical requests, refetch-on-every- navigation, and layout shift on arrival are all observable in a browser. - **Q12–Q18 (engineering, stewardship)** — judged by inspection, not the browser: read the schema, the API layer, the server code, the captured log (`agent-app` writes it under the app's `.a2app/` directory), and the git history. Probe the app's own API directly with invalid payloads and oversized list requests; provoke one error and read what the log recorded. ## Verdicts Return exactly one, with evidence: - **pass** — every functional check holds, every stored change is confirmed, and every applicable quality item holds (or is explicitly overridden by the app's spec). Only a pass announces the app to the user (and promotes a code change to live). - **defects** — one or more checks fail. Return a concrete report: for functional defects, which feature, what you did, what you expected, what happened; for quality defects, the Q-item number and the evidence. The builder fixes, relaunches, and you re-verify. - **incomplete** — some requested features are not implemented yet; list which. - **blocked** — the environment is unavailable (no browser, app will not boot). Not a failure of the app; say so and stop. Never report blocked as pass. ## Do not Do not fix the app yourself (you are the verifier). Do not soften a defect into a pass. Do not wave a quality violation through because the app is "good enough overall". Do not treat "it probably works" as verification — if you did not observe it in the running app and confirm the stored state, it is not verified. Be thorough. Be critical. Ship quality.
