Diagnose and fix errors with Codex delegation. Traces error to root cause, researches approach, delegates fix, verifies. Use when: bug reports, error messages, stack traces, test failures.
Diagnose and fix bugs with root-cause analysis and verification. Use when you have a concrete issue report, failing behavior, runtime error, or test regression that should be resolved safely. For ambiguous, high-risk, or broad-scope issues, stop and route to write-plan first.
Fix broken data scrapers and pipelines. Use when data acquisition fails, a scraper breaks, an API returns errors, or data format has changed. Also handles submitting upstream issues or PRs when the problem is in a dependency like soccerdata or kloppy.
Follow this sub-process when fixing bugs — turn the verbal description of "problem found" into a closed loop from verification to repair, leaving three documents: problem report, root cause analysis, and repair record. This process adds a buffer between "seeing the problem" and "starting to modify code" to avoid common pitfalls: the problem description in your mind disappears after the fix, you only fix the surface without analyzing the root cause, the scope of repair expands and cannot be traced, and you don't know if the fix is correct without verification after modification. This skill only acts as a router, deciding which of report / analyze / fix to proceed with based on existing artifacts. For simple problems that can be identified at a glance, a fast track will be taken, skipping the two middle steps and only retaining the fix-note.
Hard-bug DIAGNOSIS + FIX: reproduce the failure, name the cause, write a regression test, apply the minimal fix. Use whenever the user reports a bug, failure, flaky test, perf regression, error, or visible misbehaviour whose cause is not yet known — even if they only paste a symptom, stack trace, or failing test output, or say "why is X broken", "it stopped working", "it got slower", "this looks wrong". Do NOT start debugging inline without this skill: if your next step would be forming hypotheses about an unexplained failure, invoke /pasteurize first. Do NOT use for review-only diffs (/age), feature design (/mold), fixes where the cause is already known (/cook), or when the user opted out of writes (/culture).
Automated visual QA testing using Playwright — navigate web apps like a real user, capture screenshots, find bugs, and fix them.
Phase 2 of the issue process — Read the issue report + read the code, identify the true root cause and assess the repair risk, and finally provide the user with 2-3 repair plan options for them to decide. This phase is **not about starting to modify code** — after analysis, show the conclusion to the user first, and only proceed to Phase 3 after the user confirms the plan. The prerequisite dependency easysdd-issue-report has been completed. Trigger scenarios: The user says "analyze this bug", "find the root cause", "locate the issue", and the {slug}-report.md already exists in the issue directory.
Use when asked to debug, fix a bug, investigate an error, or do root cause analysis, and when users report errors, stack traces, unexpected behavior, or say something stopped working.
Use when fixing, editing, changing, or debugging existing TypeScript code and keeping changes small and proportional to what was touched.
Comet Preset Path: Bug fix / Hotfix. Skip brainstorming, go directly through open → build → verify → archive. Applicable for behavior fixes and scenarios that do not involve new capability design.
Debug and fix bugs, errors, or unexpected behavior
Use when RLM requirement involves debugging a bug, test failure, or unexpected behavior. Insert Phase 1.5 between Phase 1 and Phase 2 to perform systematic root cause analysis before attempting any fixes.
