[IMPORTANT] Use

TaskCreate
to break ALL work into small tasks BEFORE starting — including tasks for each file read. This prevents context loss from long files. For simple tasks, AI MUST ATTENTION ask user whether to skip.

<!-- SYNC:critical-thinking-mindset -->

Critical Thinking Mindset — Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence >80% to act. Anti-hallucination: Never present guess as fact — cite sources for every claim, admit uncertainty freely, self-check output for errors, cross-reference independently, stay skeptical of own confidence — certainty without evidence root of all hallucination.

<!-- /SYNC:critical-thinking-mindset --> <!-- SYNC:ai-mistake-prevention -->

AI Mistake Prevention — Failure modes to avoid on every task:

  • Check downstream references before deleting. Deleting components causes documentation and code staleness cascades. Map all referencing files before removal.
  • Verify AI-generated content against actual code. AI hallucinates APIs, class names, and method signatures. Always grep to confirm existence before documenting or referencing.
  • Trace full dependency chain after edits. Changing a definition misses downstream variables and consumers derived from it. Always trace the full chain.
  • Trace ALL code paths when verifying correctness. Confirming code exists is not confirming it executes. Always trace early exits, error branches, and conditional skips — not just happy path.
  • When debugging, ask "whose responsibility?" before fixing. Trace whether bug is in caller (wrong data) or callee (wrong handling). Fix at responsible layer — never patch symptom site.
  • Assume existing values are intentional — ask WHY before changing. Before changing any constant, limit, flag, or pattern: read comments, check git blame, examine surrounding code.
  • Verify ALL affected outputs, not just the first. Changes touching multiple stacks require verifying EVERY output. One green check is not all green checks.
  • Holistic-first debugging — resist nearest-attention trap. When investigating any failure, list EVERY precondition first (config, env vars, DB names, endpoints, DI registrations, data preconditions), then verify each against evidence before forming any code-layer hypothesis.
  • Surgical changes — apply the diff test. Bug fix: every changed line must trace directly to the bug. Don't restyle or improve adjacent code. Enhancement task: implement improvements AND announce them explicitly.
  • Surface ambiguity before coding — don't pick silently. If request has multiple interpretations, present each with effort estimate and ask. Never assume all-records, file-based, or more complex path.

Understand Code First — HARD-GATE: Do NOT write, plan, or fix until you READ existing code.

  1. Search 3+ similar patterns (
    grep
    /
    glob
    ) — cite
    file:line
    evidence
  2. Read existing files in target area — understand structure, base classes, conventions
  3. Run
    python .claude/scripts/code_graph trace <file> --direction both --json
    when
    .code-graph/graph.db
    exists
  4. Map dependencies via
    connections
    or
    callers_of
    — know what depends on your target
  5. Write investigation to
    .ai/workspace/analysis/
    for non-trivial tasks (3+ files)
  6. Re-read analysis file before implementing — never work from memory alone
  7. NEVER invent new patterns when existing ones work — match exactly or document deviation

BLOCKED until:

- [ ]
Read target files
- [ ]
Grep 3+ patterns
- [ ]
Graph trace (if graph.db exists)
- [ ]
Assumptions verified with evidence

<!-- /SYNC:understand-code-first --> <!-- SYNC:evidence-based-reasoning -->

Evidence-Based Reasoning — Speculation is FORBIDDEN. Every claim needs proof.

  1. Cite
    file:line
    , grep results, or framework docs for EVERY claim
  2. Declare confidence: >80% act freely, 60-80% verify first, <60% DO NOT recommend
  3. Cross-service validation required for architectural changes
  4. "I don't have enough evidence" is valid and expected output

BLOCKED until:

- [ ]
Evidence file path (
file:line
)
- [ ]
Grep search performed
- [ ]
3+ similar patterns found
- [ ]
Confidence level stated

Forbidden without proof: "obviously", "I think", "should be", "probably", "this is because" If incomplete → output:

"Insufficient evidence. Verified: [...]. Not verified: [...]."

— debug and fix GitHub issues with systematic investigation.

Quick Summary

Goal: Investigate and fix bugs reported as GitHub issues with full traceability.

Workflow:

  1. Fetch — Read GitHub issue details (title, description, reproduction steps)
  2. Reproduce — Trace the reported behavior in code
  3. Fix — Apply fix with root cause evidence

Key Rules:

  • Debug Mindset: every claim needs
    file:line
    evidence
  • Link fix back to the GitHub issue for traceability
  • Verify fix addresses the specific reproduction steps from the issue
<!-- SYNC:root-cause-debugging -->

Root Cause Debugging — Systematic approach, never guess-and-check.

  1. Reproduce — Confirm the issue exists with evidence (error message, stack trace, screenshot)
  2. Isolate — Narrow to specific file/function/line using binary search + graph trace
  3. Trace — Follow data flow from input to failure point. Read actual code, don't infer.
  4. Hypothesize — Form theory with confidence %. State what evidence supports/contradicts it
  5. Verify — Test hypothesis with targeted grep/read. One variable at a time.
  6. Fix — Address root cause, not symptoms. Verify fix doesn't break callers via graph
    connections

NEVER: Guess without evidence. Fix symptoms instead of cause. Skip reproduction step.

Debug Mindset (NON-NEGOTIABLE)

Be skeptical. Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence percentages (Idea should be more than 80%).

  • Do NOT assume the first hypothesis is correct — verify with actual code traces
  • Every root cause claim must include
    file:line
    evidence
  • If you cannot prove a root cause with a code trace, state "hypothesis, not confirmed"
  • Question assumptions: "Is this really the cause?" → trace the actual execution path
  • Challenge completeness: "Are there other contributing factors?" → check related code paths
  • No "should fix it" without proof — verify the fix addresses the traced root cause

⚠️ MANDATORY: Confidence & Evidence Gate

MANDATORY IMPORTANT MUST ATTENTION declare

Confidence: X%
with evidence list +
file:line
proof for EVERY claim. 95%+ recommend freely | 80-94% with caveats | 60-79% list unknowns | <60% STOP — gather more evidence.

⚠️ Validate Before Fix (NON-NEGOTIABLE): After root cause analysis, MUST ATTENTION present findings + proposed fix to user via

AskUserQuestion
and get explicit approval BEFORE any code changes. No silent fixes.

Activate

debug-investigate
skill and follow its workflow.

IMPORTANT: Always use external memory at

.ai/workspace/analysis/issue-[number].analysis.md
for structured analysis. Re-read ENTIRE analysis file before proposing any fix — this prevents knowledge loss.

🛑 Present root cause + proposed fix →

AskUserQuestion
→ wait for user approval before implementing.

See

.claude/docs/AI-DEBUGGING-PROTOCOL.md
for comprehensive guidelines.

⚠️ MANDATORY: Post-Fix Verification

After applying the fix, MUST ATTENTION run

/prove-fix
— build code proof traces per change with confidence scores. Never skip.


Standalone Review Gate (Non-Workflow Only)

MANDATORY IMPORTANT MUST ATTENTION: If this skill is called outside a workflow (standalone

/fix-issue
), you MUST ATTENTION create a
TaskCreate
todo task for
/review-changes
as the last task in your task list. This ensures all changes are reviewed before commit even without a workflow enforcing it.

If already running inside a workflow (e.g.,

bugfix
), skip this — the workflow sequence handles
/review-changes
at the appropriate step.

Closing Reminders

MANDATORY IMPORTANT MUST ATTENTION break work into small todo tasks using

TaskCreate
BEFORE starting. MANDATORY IMPORTANT MUST ATTENTION validate decisions with user via
AskUserQuestion
— never auto-decide. MANDATORY IMPORTANT MUST ATTENTION add a final review todo task to verify work quality. MANDATORY IMPORTANT MUST ATTENTION READ the following files before starting:
