Verification Gate

Use this skill after implementation and before commit or merge.

Keep the scope narrow:

•Prove the intended task outcome works.
•Choose the lightest verification mode that creates confidence.
•Return a clear verdict with evidence.

Do not use this skill for exploratory QA or bug hunting. Use dogfood for that.

Preflight

Before starting any browser verification:

•Confirm the agent-browser skill is available and read it first for setup and usage.
•If browser verification is needed but agent-browser is not ready, do not loop on failing browser steps. Return BLOCKED with the missing setup or prerequisite.

Inputs

Collect the minimum context needed to verify the work:

•task goal
•acceptance criteria or success definition
•changed behavior or files
•target URL, command, or environment
•auth, seed data, or other prerequisites

If key prerequisites are missing and you cannot verify safely, return BLOCKED.

Modes

Choose exactly one primary mode:

•
browser-flow
- •Use for multi-step UI flows, async state transitions, persisted state, uploads, or other behavior that must be proven end to end in the browser.
•
browser-static
- •Use for simple render, layout, copy, or visible-state checks where screenshots are enough.
•
non-browser
- •Use for backend, CLI, API, data, or other tasks where browser proof adds no value.

Prefer the smallest proof path that still demonstrates real user value.

Workflow

•
Define the verification objective.
- •State the single main user outcome that must work.
- •Add one lightweight regression check when adjacent behavior could easily break.
•
Map the proof flow.
- •Start from the first meaningful user or system action.
- •End at the success state the user cares about.
- •Avoid padding the flow with irrelevant steps.
•
Execute verification.
- •
  For browser-flow or browser-static, use the agent-browser skill instead of re-inventing browser steps.
- •
  Follow the snapshot -> interact -> re-snapshot cadence.
- •
  Use named sessions.
- •
  When needed, read:
  - •.opencode/skills/agent-browser/references/snapshot-refs.md
  - •.opencode/skills/agent-browser/references/session-management.md
  - •.opencode/skills/agent-browser/references/video-recording.md
- •
  Use 📸 screenshots for static proof points.
- •
  Use 🎥 recordings only for multi-step interactions or async transitions that are hard to prove with screenshots alone.
- •
  For non-browser, run the smallest direct proof path available.
- •
  Prefer assertions tied to user-visible outcomes: command success, API response shape, file creation, persisted data, or other concrete results.
•
Decide the verdict.
- •PASS: the main flow completes and the success state is proven.
- •FAIL: the flow breaks, the result is wrong, or the outcome cannot be proven.
- •BLOCKED: required auth, data, environment, or tooling is missing.
•
Report the result.

Evidence Rules

•Prove the whole flow, not just the final screen.
•Capture only the evidence needed to support the verdict.
•Never record secrets, tokens, private user data, or unnecessary personal information.
•If a task directory exists, store artifacts under _ai/task/{SLUG}/verification/ with screenshots/ and videos/ subfolders.
•Always include artifact paths in the final report when evidence exists.

Output

Use this exact structure:

## Verification Result

- Mode: `browser-flow|browser-static|non-browser`
- Objective: [single outcome verified]
- Primary flow: [short description]
- Regression check: [short description or "None"]
- Verdict: `PASS|FAIL|BLOCKED`

### Evidence

- [artifact path or "No artifacts"]

### Notes

- [key proof point, failure point, or blocker]

### Next Action

- [commit / fix issue / unblock environment]

Examples

•browser-flow: Select model -> enter prompt -> submit -> generated images appear.
•browser-static: Open settings page -> verify new card, copy, and CTA render correctly.
•non-browser: Run export command -> confirm output file exists and contains expected records.
