bugfix-workflow

bugfix-workflow is a skill for Claude Code from arozumenko/sdlc-skills. It costs 16 tokens per session (949 once invoked), scanned A, original, MIT.

A bug-fixing workflow for software projects that follows the sequence reproduce, test, diagnose, fix, and verify. It also connects the work to an issue or ticket in the project's tracking system.

In plain words
What is it for?
Use it to investigate a reported bug, reproduce the failure, add a failing test, find the cause, implement the fix, verify it, and document the result on the relevant ticket.
Why use it?
It reduces the risk of changing code before confirming the bug or declaring success without testing the fix. The structured process keeps investigation and verification visible.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.
    Fix: Limit the skill's scope to its documented purpose. Remove instructions that enable the agent to perform actions outside its stated functionality.

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

bugfix-workflow 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 7d 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 — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Bugfix Workflow: Reproduce → Test → Fix → Verify

Core philosophy: reproduce before you fix, verify after you fix, link everything to the ticket.

Platform & systems

gh issue … / gh pr … below are the GitHub reference. Translate to your tracker per .agents/profile.md § Project systems (jira / gitlab-issues / azure-boards / linear) and your code host's CLI per .agents/workflow.md (GitLab glab, Azure DevOps az repos, Bitbucket bb, Gitea tea). If scout hasn't recorded them, ask before assuming GitHub.

The seven steps

1. Read & understand the bug
2. Reproduce
3. Write a failing test
4. Root cause analysis
5. Implement the fix
6. Verify
7. Document on ticket

1. Read & understand the bug

gh issue view <N>. Identify expected vs actual behavior, files involved, error messages, stack traces, related issues. Post a 🔧 **Investigating** comment on the ticket so the reporter knows work has started.

2. Reproduce

Confirm the bug exists and understand the exact conditions that trigger it. For the full method — UI / API / logic / intermittent attempts and the CONFIRMED / CANNOT-REPRODUCE confirmation gate — use the reproducing-issues skill. UI bugs → Playwright MCP snapshots. API bugs → curl. Logic bugs → minimal reproducer script.

If you cannot reproduce, stop and ask. Do not proceed to fix a bug you cannot observe. Post what you tried and request more details.

Once reproduced, post a ✅ **Reproduced** comment with steps, expected, actual, and frequency (always / intermittent).

3. Write a failing test

Capture the bug as a regression test before fixing. Run it and confirm it fails — that's the whole point. A passing test for an unfixed bug means the test doesn't exercise the bug.

4. Root cause analysis

Trace the bug to its exact cause — for the full method (execution-path tracing, root-cause classification, confidence, impact/regression analysis) use the root-cause-analysis skill. Locate the code, trace execution from entry point to failure, classify the cause (logic / data / concurrency / config / integration / resource), and assess blast radius — what else uses this code, could the fix break anything else?

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.

bugfix-workflow is a skill published in the GitHub repository arozumenko/sdlc-skills (20 stars, last pushed 3d ago), licensed MIT. It adds 16 tokens to every session and 949 once invoked, about $0.0001 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.
