structured-debug

GitHub

指导在修改代码前进行结构化调试。遵循证据优先工作流，包括澄清预期行为、复现问题、假设验证及制定修复计划。禁止未经批准修改代码，强调通过最小化复现和单变量测试定位根因，并记录知识以备后用。

    "name": "structured-debug",
    "description": "AI DevKit · Guide structured debugging before code changes by clarifying expected behavior, reproducing issues, identifying likely root causes, and agreeing on a fix plan with validation steps. Use when users ask to debug bugs, investigate regressions, triage incidents, diagnose failing behavior, handle failing tests, analyze production incidents, investigate error spikes, or run root cause analysis (RCA)."

Local Debugging Assistant

Debug with an evidence-first workflow before changing code.

Hard Rule

Do not modify code until the user approves a selected fix plan.

Workflow

Clarify

Restate observed vs expected behavior in one concise diff.
Confirm scope and measurable success criteria.
Before investigating, search for similar past incidents: npx ai-devkit@latest memory search --query "<observed behavior>" --tags "debug,root-cause"

Reproduce

Capture minimal reproduction steps.
Capture environment fingerprint: runtime, versions, config flags, data sample, and platform.

Hypothesize and Test For each hypothesis, include:

Predicted evidence if true.
Disconfirming evidence if false.
Exact test command or check.
Prefer one-variable-at-a-time tests.

Plan

Present fix options with risks and verification steps.
Recommend one option and request approval.

Validation

Confirm a pre-fix failing signal exists.
Confirm post-fix success using the verify skill — including regression verification for bug fixes.
Summarize remaining risks and follow-ups.
Store root cause and fix for future sessions: npx ai-devkit@latest memory store --title "<root cause>" --content "<diagnosis and fix>" --tags "debug,root-cause"

Task Tracing

If task tracing is usable, choose a short kebab-case debug task name when no task name exists, then use task optionally: record repro/final results as evidence, the current hypothesis as next, and blockers only when they materially affect progress. Never block debugging because task tracing is unavailable.

Red Flags and Rationalizations

Rationalization	Why It's Wrong	Do Instead
"I already know the cause"	Assumptions skip evidence	Reproduce and prove it first
"This is urgent, just fix it"	A wrong fix wastes more time	10 minutes of diagnosis saves hours
"The fix is obvious from the stack trace"	Stack traces show symptoms, not causes	Trace backward to the root cause
