[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.

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.

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.

Quick Summary

Goal: Stage changes and create well-structured git commits following Conventional Commits format.

Workflow:

1. Analyze Changes — Run git status/diff to understand staged and unstaged changes
2. Stage Changes — Add relevant files (specific or all)
3. Generate Message — Detect type (feat/fix/refactor/etc.), extract scope from paths, write subject
4. Commit — Create commit with HEREDOC and attribution footer
5. Verify — Confirm with git status and git log

Key Rules:

• DO NOT push unless explicitly requested
• Never commit secrets, credentials, or .env files
• Never use

  --amend

  or

  --no-verify

  unless explicitly requested
• Include

  attribution footer

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

Git Commit Skill

Stage changes and create well-structured git commits following Conventional Commits format.

IMPORTANT: Bypass git-commit-block Hook

Before running any

git add

git commit

git-commit-block

PROJ=$(git rev-parse --show-toplevel) && mkdir -p "$PROJ/tmp/claude-temp" && touch "$PROJ/tmp/claude-temp/.commit-skill-active"

After committing (success or failure), always clean up the marker:

rm -f "$(git rev-parse --show-toplevel)/tmp/claude-temp/.commit-skill-active"

Workflow

Step 1: Analyze Changes

# Check current status (never use -uall flag)
git status

# See staged changes
git diff --cached

# See unstaged changes
git diff

# Check recent commit style
git log --oneline -5

Step 2: Stage Changes

# Stage all changes
git add .

# Or stage specific files
git add <file-path>

Step 2.5: Docs-Update Triage

Before committing, check if staged files impact documentation:

1. Run

   git diff --name-only --cached

   to list staged files
2. Check if any staged file matches doc-impact patterns:

   • src/Services/**

     → may impact

     docs/business-features/

   • .claude/skills/**

     → may impact

     .claude/docs/skills/

   • .claude/hooks/**

     → may impact

     .claude/docs/hooks/

   • .claude/workflows.json

     → may impact

     CLAUDE.md

     workflow table

   • src/WebV2/**

     → may impact frontend pattern docs
3. If matches found: invoke

   /docs-update

   skill, then re-stage any doc changes with

   git add

4. If no matches: skip (log "No doc-impacting files staged")

Step 3: Generate Commit Message

Analyze staged changes and generate message following Conventional Commits:

<type>(<scope>): <subject>

Type Detection

feat

fix

refactor

docs

test

chore

perf

style

Scope Rules

Extract from file paths:

• src/auth/

  →

  auth

• .claude/skills/

  →

  claude-skills

• libs/{shared-lib}/

  →

  {shared-lib}

• Multiple unrelated areas → omit scope

Subject Rules

• Imperative mood ("add" not "added")
• Lowercase start
• No period at end
• Max 50 characters

Step 4: Commit

Use HEREDOC for proper formatting:

git commit -m "$(cat <<'EOF'
type(scope): subject

Generated with [Claude Code](https://claude.com/claude-code)
EOF
)"

Step 5: Verify

git status
git log -1

Examples

feat(employee): add department filter to list
fix(validation): handle empty date range
refactor(auth): extract token validation to service
chore(deps): update Angular to v19
chore(claude-skills): add commit skill
docs(readme): update installation instructions

Critical Rules

• ALWAYS stage all unstaged changes before committing — run

  git add .

  (or specific files) so nothing is left behind
• DO NOT push to remote unless explicitly requested
• Review staged changes before committing
• Never commit secrets, credentials, or .env files
• Never use

  git commit --amend

  unless explicitly requested AND the commit was created in this session AND not yet pushed
• Never skip hooks with

  --no-verify

  unless explicitly requested
• Include attribution footer:
