reproducing-issues

reproducing-issues is a skill for Claude Code from arozumenko/sdlc-skills. It costs 66 tokens per session (892 once invoked), scanned A, original, MIT.

A process for checking whether a reported software bug can be reproduced. It turns an unclear report into repeatable steps, evidence, and a confirmed, partial, or cannot-reproduce result.

In plain words
What is it for?
Use it to set up the right environment, run the reported steps, test unclear or intermittent behavior, capture evidence, and document the result on the issue tracker.
Why use it?
It separates real, reproducible failures from incomplete or intermittent reports before anyone investigates or changes the code.

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

reproducing-issues scanned grade A with 1 finding 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Reproducing Issues

Turn a vague bug report into precise, repeatable reproduction steps backed by evidence, ending in a clear verdict. Reproduction and documentation only — you do NOT fix code.

Platform & systems

Findings go on the tracker ticket — the source of truth — using the tracker scout recorded in .agents/profile.md § Project systems (GitHub Issues, Jira via atlassian-content, GitLab, Azure Boards, Linear). The gh issue … commands below are the GitHub reference; translate per .agents/workflow.md § Git host. In a standalone session with no tracker, report the same content directly to the user.

Methodology — 5 phases

1. Intake

Read the report in full (gh issue view <N> or the tracker equivalent). Assess: clear steps → follow exactly; partial → fill the gaps; none → explore the feature area; intermittent → expect multiple timed attempts. Note that reproduction has started on the ticket.

2. Environment setup

Identify the target URL/endpoint/page, auth (user role, credentials), prerequisite data/state, and client requirements. Reproduction must be repeatable — document the environment.

3. Reproduction attempts

  • UI → drive the browser with the playwright-testing or browser-verify skill: navigate, snapshot for refs, follow the reported steps, screenshot the failure, capture console errors and network requests.
  • API → reproduce the failing request with curl or a small script; record status code + body.
  • Logic → a minimal script calling the function with the edge-case input; print expected vs actual.
  • Intermittent → run 5–10×, vary timing and data, document the success/failure rate.

4. Root-cause hints (handoff to RCA)

Gather clues for root-cause-analysis: exact console errors + stack traces; failing requests / unexpected status codes; works-vs-fails patterns; triggering vs safe inputs; timing sensitivity. Post these technical observations on the ticket.

5. Confirmation gate (required)

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

reproducing-issues is a skill published in the GitHub repository arozumenko/sdlc-skills (20 stars, last pushed 5d ago), licensed MIT. It adds 66 tokens to every session and 892 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
