common-skills: Skill for Claude Code

.agents/skills/reproduce-bug-report/SKILL.md

reproduce-bug-report is a skill for Claude Code, Codex from warpdotdev/common-skills. It costs 56 tokens per session (2,484 once invoked), scanned A, original, MIT.

A bug-investigation workflow that uses remote agents with computer control to reproduce bugs visible in an application and capture visual evidence.

In plain words
What is it for?
It helps reproduce UI, rendering, window, settings, onboarding, editor, and terminal-display bugs from issues, tickets, support reports, or prompts.
Why use it?
It helps confirm what happens in an interactive bug report and gives engineers a recording or screenshots to examine.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

reproduce-bug-report scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Reproduce bug report

Use this skill when the current context is a GitHub issue, support report, Linear ticket, or user prompt describing a specific bug that may be reproduced through visible application behavior. It is primarily for UI, rendering, windowing, settings, editor, terminal-display, onboarding, or other interactive bugs where a screen recording (or screenshots) makes the result more actionable.

The parent agent should not try to manually reproduce the UI bug locally unless the user explicitly asks. Launch one or more Oz cloud agents with computer use enabled so they can run the relevant app, interact with it, and capture visual evidence.

Parent workflow

  1. Read the bug report carefully and extract:
    • reported behavior
    • expected behavior
    • reproduction steps, if provided
    • OS, app version/build/channel, shell, feature flags, account state, or other environment constraints when relevant
    • attached screenshots, videos, logs, or comments that narrow the repro path
  2. Decide whether this skill applies:
    • Use it for UI-visible bugs, interaction bugs, rendering/layout bugs, onboarding bugs, and bugs where a screen recording (or screenshots) would be useful.
    • Do not use it for purely backend, CI, build, dependency, or text-only code issues unless the prompt specifically asks for visual reproduction.
    • If the report requires credentials, private account state, or another capability not available to the repro environment, report that constraint clearly instead of guessing.
  3. If the reproduction path is straightforward, launch one Oz cloud agent with computer use.
  4. If there are multiple plausible repro paths, launch several Oz cloud agents in one run_agents batch. Give each child a distinct hypothesis or environment variant, such as:
    • different OS or desktop environment
    • fresh first-run state vs an already-initialized local state
    • stable vs dev build
    • fresh settings vs existing settings
    • different shells, prompts, pane layouts, or settings toggles
  5. If steps are incomplete, use codebase knowledge to propose likely app states and assign children to investigate those states. Do not invent facts about the original reporter's environment.
  6. Wait for all children to report before summarizing. Distinguish confirmed reproduction, partial reproduction, non-reproduction, blockers, and untested hypotheses.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
