Agent Skills: Reproduce Bug

Lightweight SOP for reproducing bugs and proving whether a reported issue can be triggered. Use when Claude needs to reproduce a bug, validate a bug report, capture a repro video or screenshot, and return a clear REPRODUCED/NOT_REPRODUCED/BLOCKED result. When browser-based reproduction is needed, rely on the dogfood skill for browser setup, navigation, and evidence capture.

Description
Lightweight SOP for reproducing bugs and proving whether a reported issue can be triggered. Use when Claude needs to reproduce a bug, validate a bug report, capture a repro video or screenshot, and return a clear REPRODUCED/NOT_REPRODUCED/BLOCKED result. When browser-based reproduction is needed, rely on the dogfood skill for browser setup, navigation, and evidence capture.

Reproduce Bug

Use this skill when the goal is to reproduce a reported bug quickly and with low friction.

Keep the scope narrow:

  • Prove whether the reported bug can be reproduced.
  • Capture the lightest evidence that makes the result clear.
  • Return a clear result with repro steps and artifact paths.

Do not use this skill for broad QA, new bug discovery, or root-cause analysis.

Preflight

Before starting any browser-based reproduction:

  • Confirm the dogfood skill is available and read it first for browser setup and evidence capture.
  • If browser reproduction is needed but dogfood is not ready, do not loop on failing browser steps. Return BLOCKED with the missing setup or prerequisite.

Inputs

Collect only the context needed to attempt reproduction:

  • bug summary
  • expected behavior
  • actual behavior
  • starting URL, screen, command, or environment
  • known repro steps, if any
  • account, auth, test data, or feature flag prerequisites

If the bug report is vague, reduce it to one testable repro target before proceeding.

Modes

Choose exactly one primary mode:

  1. browser-interactive
    • Use when the bug requires clicks, typing, navigation, async state changes, or a multi-step user journey.
  2. browser-static
    • Use when the bug is visible on load and a screenshot is enough to prove it.
  3. non-browser
    • Use when the bug is reproduced more directly through a command, API call, file output, log, or data check.

Prefer the smallest repro path that still proves the bug clearly.

Workflow

  1. Define the repro target.

    • State the exact behavior you are trying to trigger.
    • Keep it to one bug at a time.

  2. Map the shortest repro flow.

    • Start from the first meaningful action.
    • End at the exact failing state or at proof that the bug did not occur.
    • Avoid extra setup steps unless they are required to trigger the issue.

  3. Attempt reproduction.

    • For browser-interactive or browser-static, use the dogfood skill instead of rebuilding browser repro instructions here.

    • Reuse the smallest part of the dogfood workflow needed to reproduce the reported bug.

    • Capture 📸 when a single static proof state is enough.

    • Capture 🎥 when the bug requires interaction or timing proof; prefer one recording for the full sequence.

    • For non-browser, run the shortest direct repro path available.

    • Prefer concrete proof: failing output, wrong response, missing file, broken state, or other observable result.

  4. Decide the result.

    • REPRODUCED: the reported bug was triggered and proven.
    • NOT_REPRODUCED: the reported bug did not occur after a reasonable attempt.
    • BLOCKED: required auth, data, environment, or tooling is missing.

  5. Report the result.

Evidence Rules

  • Match the evidence to the bug.
  • Use screenshots for static visible issues.
  • Use a single full-sequence video for interaction-heavy repros.
  • Never capture secrets, tokens, private user data, or unnecessary personal information.
  • If a task directory exists, store artifacts under _ai/task/{SLUG}/reproduction/ with screenshots/ and videos/ subfolders.
  • Always include artifact paths when evidence exists.

Output

Use this exact structure:

## Reproduction Result

- Mode: `browser-interactive|browser-static|non-browser`
- Bug: [short bug summary]
- Repro target: [exact behavior tested]
- Result: `REPRODUCED|NOT_REPRODUCED|BLOCKED`

### Repro Steps

- [short numbered or ordered steps]

### Evidence

- [artifact path or "No artifacts"]

### Notes

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

### Next Action

- [fix bug / refine bug report / unblock environment]

Examples

  • browser-interactive: Open settings -> toggle notifications -> save -> page resets and loses the new state.
  • browser-static: Open pricing page -> CTA text is clipped on mobile.
  • non-browser: Run import command -> command exits successfully but no output file is created.
