+**Execute ALL of the following commands IN PARALLEL to minimize latency:**
+
+\`\`\`bash
+# Group 1: Current state
+git status
+git diff --staged --stat
+git diff --stat
+
+# Group 2: History context  
+git log -30 --oneline

+1. What files changed (staged vs unstaged)
+2. Recent 30 commit messages for style detection
+3. Branch position relative to main/master
+4. Whether branch has upstream tracking
+5. Commits that would go in PR (local only)
+</parallel_analysis>
+
+---
+
+## PHASE 1: Style Detection (BLOCKING - MUST OUTPUT BEFORE PROCEEDING)
+
+<style_detection>
+**THIS PHASE HAS MANDATORY OUTPUT** - You MUST print the analysis result before moving to Phase 2.
+
+### 1.1 Language Detection
+
+\`\`\`
+Count from git log -30:
+- Korean characters: N commits
+- English only: M commits
+- Mixed: K commits
+
+DECISION:
+- If Korean >= 50% -> KOREAN
+- If English >= 50% -> ENGLISH  
+- If Mixed -> Use MAJORITY language
+\`\`\`
+
+### 1.2 Commit Style Classification
+
+| Style | Pattern | Example | Detection Regex |
+|-------|---------|---------|-----------------|
+| \`SEMANTIC\` | \`type: message\` or \`type(scope): message\` | \`feat: add login\` | \`/^(feat\\|fix\\|chore\\|refactor\\|docs\\|test\\|ci\\|style\\|perf\\|build)(\\(.+\\))?:/\` |
+| \`PLAIN\` | Just description, no prefix | \`Add login feature\` | No conventional prefix, >3 words |
+| \`SENTENCE\` | Full sentence style | \`Implemented the new login flow\` | Complete grammatical sentence |
+| \`SHORT\` | Minimal keywords | \`format\`, \`lint\` | 1-3 words only |
+
+**Detection Algorithm:**
+\`\`\`
+semantic_count = commits matching semantic regex
+plain_count = non-semantic commits with >3 words
+short_count = commits with <=3 words
+
+IF semantic_count >= 15 (50%): STYLE = SEMANTIC
+ELSE IF plain_count >= 15: STYLE = PLAIN  
+ELSE IF short_count >= 10: STYLE = SHORT
+ELSE: STYLE = PLAIN (safe default)
+\`\`\`
+
+### 1.3 MANDATORY OUTPUT (BLOCKING)
+
+**You MUST output this block before proceeding to Phase 2. NO EXCEPTIONS.**
+
+\`\`\`
+STYLE DETECTION RESULT
+======================
+Analyzed: 30 commits from git log
+
+Language: [KOREAN | ENGLISH]
+  - Korean commits: N (X%)
+  - English commits: M (Y%)
+
+Style: [SEMANTIC | PLAIN | SENTENCE | SHORT]
+  - Semantic (feat:, fix:, etc): N (X%)
+  - Plain: M (Y%)
+  - Short: K (Z%)
+
+Reference examples from repo:
+  1. "actual commit message from log"
+  2. "actual commit message from log"
+  3. "actual commit message from log"
+
+All commits will follow: [LANGUAGE] + [STYLE]
+\`\`\`
+
+**IF YOU SKIP THIS OUTPUT, YOUR COMMITS WILL BE WRONG. STOP AND REDO.**
+</style_detection>
+
+---
+
+## PHASE 2: Branch Context Analysis
+
+<branch_analysis>
+### 2.1 Determine Branch State
+
+\`\`\`
+BRANCH_STATE:
+  current_branch: <name>
+  has_upstream: true | false
+  commits_ahead: N  # Local-only commits
+  merge_base: <hash>
+  
+REWRITE_SAFETY:
+  - If has_upstream AND commits_ahead > 0 AND already pushed:
+    -> WARN before force push
+  - If no upstream OR all commits local:
+    -> Safe for aggressive rewrite (fixup, reset, rebase)
+  - If on main/master:
+    -> NEVER rewrite, only new commits
+\`\`\`
+
+### 2.2 History Rewrite Strategy Decision
+
+\`\`\`
+IF current_branch == main OR current_branch == master:
+  -> STRATEGY = NEW_COMMITS_ONLY
+  -> Never fixup, never rebase
+
+ELSE IF commits_ahead == 0:
+  -> STRATEGY = NEW_COMMITS_ONLY
+  -> No history to rewrite
+
+ELSE IF all commits are local (not pushed):
+  -> STRATEGY = AGGRESSIVE_REWRITE
+  -> Fixup freely, reset if needed, rebase to clean
+
+ELSE IF pushed but not merged:
+  -> STRATEGY = CAREFUL_REWRITE  
+  -> Fixup OK but warn about force push
+\`\`\`
+</branch_analysis>
+
+---
+
+## PHASE 3: Atomic Unit Planning (BLOCKING - MUST OUTPUT BEFORE PROCEEDING)
+
+<atomic_planning>
+**THIS PHASE HAS MANDATORY OUTPUT** - You MUST print the commit plan before moving to Phase 4.
+
+### 3.0 Calculate Minimum Commit Count FIRST
+
+\`\`\`
+FORMULA: min_commits = ceil(file_count / 3)
+
+ 3 files -> min 1 commit
+ 5 files -> min 2 commits
+ 9 files -> min 3 commits
+15 files -> min 5 commits
+\`\`\`
+
+**If your planned commit count < min_commits -> WRONG. SPLIT MORE.**
+
+### 3.1 Split by Directory/Module FIRST (Primary Split)
+
+**RULE: Different directories = Different commits (almost always)**
+
+\`\`\`
+Example: 8 changed files
+  - app/[locale]/page.tsx
+  - app/[locale]/layout.tsx
+  - components/demo/browser-frame.tsx
+  - components/demo/shopify-full-site.tsx
+  - components/pricing/pricing-table.tsx
+  - e2e/navbar.spec.ts
+  - messages/en.json
+  - messages/ko.json
+
+WRONG: 1 commit "Update landing page" (LAZY, WRONG)
+WRONG: 2 commits (still too few)
+
+CORRECT: Split by directory/concern:
+  - Commit 1: app/[locale]/page.tsx + layout.tsx (app layer)
+  - Commit 2: components/demo/* (demo components)
+  - Commit 3: components/pricing/* (pricing components)
+  - Commit 4: e2e/* (tests)
+  - Commit 5: messages/* (i18n)
+  = 5 commits from 8 files (CORRECT)
+\`\`\`
+
+### 3.2 Split by Concern SECOND (Secondary Split)
+
+**Within same directory, split by logical concern:**
+
+\`\`\`
+Example: components/demo/ has 4 files
+  - browser-frame.tsx (UI frame)
+  - shopify-full-site.tsx (specific demo)
+  - review-dashboard.tsx (NEW - specific demo)
+  - tone-settings.tsx (NEW - specific demo)
+
+Option A (acceptable): 1 commit if ALL tightly coupled
+Option B (preferred): 2 commits
+  - Commit: "Update existing demo components" (browser-frame, shopify)
+  - Commit: "Add new demo components" (review-dashboard, tone-settings)
+\`\`\`
+
+### 3.3 NEVER Do This (Anti-Pattern Examples)
+
+\`\`\`
+WRONG: "Refactor entire landing page" - 1 commit with 15 files
+WRONG: "Update components and tests" - 1 commit mixing concerns
+WRONG: "Big update" - Any commit touching 5+ unrelated files
+
+RIGHT: Multiple focused commits, each 1-4 files max
+RIGHT: Each commit message describes ONE specific change
+RIGHT: A reviewer can understand each commit in 30 seconds
+\`\`\`
+
+### 3.4 Implementation + Test Pairing (MANDATORY)
+
+\`\`\`
+RULE: Test files MUST be in same commit as implementation
+
+Test patterns to match:
+- test_*.py <-> *.py
+- *_test.py <-> *.py
+- *.test.ts <-> *.ts
+- *.spec.ts <-> *.ts
+- __tests__/*.ts <-> *.ts
+- tests/*.py <-> src/*.py
+\`\`\`
+
+### 3.5 MANDATORY JUSTIFICATION (Before Creating Commit Plan)
+
+**NON-NEGOTIABLE: Before finalizing your commit plan, you MUST:**
+
+\`\`\`
+FOR EACH planned commit with 3+ files:
+  1. List all files in this commit
+  2. Write ONE sentence explaining why they MUST be together
+  3. If you can't write that sentence -> SPLIT
+  
+TEMPLATE:
+"Commit N contains [files] because [specific reason they are inseparable]."
+
+VALID reasons:
+  VALID: "implementation file + its direct test file"
+  VALID: "type definition + the only file that uses it"
+  VALID: "migration + model change (would break without both)"
+  
+INVALID reasons (MUST SPLIT instead):
+  INVALID: "all related to feature X" (too vague)
+  INVALID: "part of the same PR" (not a reason)
+  INVALID: "they were changed together" (not a reason)
+  INVALID: "makes sense to group" (not a reason)
+\`\`\`
+
+**OUTPUT THIS JUSTIFICATION in your analysis before executing commits.**
+
+### 3.7 Dependency Ordering
+
+\`\`\`
+Level 0: Utilities, constants, type definitions
+Level 1: Models, schemas, interfaces
+Level 2: Services, business logic
+Level 3: API endpoints, controllers
+Level 4: Configuration, infrastructure
+
+COMMIT ORDER: Level 0 -> Level 1 -> Level 2 -> Level 3 -> Level 4
+\`\`\`
+
+### 3.8 Create Commit Groups
+
+For each logical feature/change:
+\`\`\`yaml
+- group_id: 1
+  feature: "Add Shopify discount deletion"
+  files:
+    - errors/shopify_error.py
+    - types/delete_input.py
+    - mutations/update_contract.py
+    - tests/test_update_contract.py
+  dependency_level: 2
+  target_commit: null | <existing-hash>  # null = new, hash = fixup
+\`\`\`
+
+### 3.9 MANDATORY OUTPUT (BLOCKING)
+
+**You MUST output this block before proceeding to Phase 4. NO EXCEPTIONS.**
+
+\`\`\`
+COMMIT PLAN
+===========
+Files changed: N
+Minimum commits required: ceil(N/3) = M
+Planned commits: K
+Status: K >= M (PASS) | K < M (FAIL - must split more)
+
+COMMIT 1: [message in detected style]
+  - path/to/file1.py
+  - path/to/file1_test.py
+  Justification: implementation + its test
+
+COMMIT 2: [message in detected style]
+  - path/to/file2.py
+  Justification: independent utility function
+
+COMMIT 3: [message in detected style]
+  - config/settings.py
+  - config/constants.py
+  Justification: tightly coupled config changes
+
+Execution order: Commit 1 -> Commit 2 -> Commit 3
+(follows dependency: Level 0 -> Level 1 -> Level 2 -> ...)
+\`\`\`
+
+**VALIDATION BEFORE EXECUTION:**
+- Each commit has <=4 files (or justified)
+- Each commit message matches detected STYLE + LANGUAGE
+- Test files paired with implementation
+- Different directories = different commits (or justified)
+- Total commits >= min_commits
+
+**IF ANY CHECK FAILS, DO NOT PROCEED. REPLAN.**
+</atomic_planning>
+
+---
+
+## PHASE 4: Commit Strategy Decision
+
+<strategy_decision>
+### 4.1 For Each Commit Group, Decide:
+
+\`\`\`
+FIXUP if:
+  - Change complements existing commit's intent
+  - Same feature, fixing bugs or adding missing parts
+  - Review feedback incorporation
+  - Target commit exists in local history
+
+NEW COMMIT if:
+  - New feature or capability
+  - Independent logical unit
+  - Different issue/ticket
+  - No suitable target commit exists
+\`\`\`
+
+### 4.2 History Rebuild Decision (Aggressive Option)
+
+\`\`\`
+CONSIDER RESET & REBUILD when:
+  - History is messy (many small fixups already)
+  - Commits are not atomic (mixed concerns)
+  - Dependency order is wrong
+  
+RESET WORKFLOW:
+  1. git reset --soft $(git merge-base HEAD main)
+  2. All changes now staged
+  3. Re-commit in proper atomic units
+  4. Clean history from scratch
+  
+ONLY IF:
+  - All commits are local (not pushed)
+  - User explicitly allows OR branch is clearly WIP
+\`\`\`
+
+### 4.3 Final Plan Summary
+
+\`\`\`yaml
+EXECUTION_PLAN:
+  strategy: FIXUP_THEN_NEW | NEW_ONLY | RESET_REBUILD
+  fixup_commits:
+    - files: [...]
+      target: <hash>
+  new_commits:
+    - files: [...]
+      message: "..."
+      level: N
+  requires_force_push: true | false
+\`\`\`
+</strategy_decision>
+
+---
+
+## PHASE 5: Commit Execution
+
+<execution>
+### 5.1 Register TODO Items
+
+Use TodoWrite to register each commit as a trackable item:
+\`\`\`
+- [ ] Fixup: <description> -> <target-hash>
+- [ ] New: <description>
+- [ ] Rebase autosquash
+- [ ] Final verification
+\`\`\`
+
+### 5.2 Fixup Commits (If Any)
+
+\`\`\`bash
+# Stage files for each fixup
+git add <files>
+git commit --fixup=<target-hash>
+
+# Repeat for all fixups...
+
+# Single autosquash rebase at the end
+MERGE_BASE=$(git merge-base HEAD main 2>/dev/null || git merge-base HEAD master)
+GIT_SEQUENCE_EDITOR=: git rebase -i --autosquash $MERGE_BASE
+\`\`\`
+
+### 5.3 New Commits (After Fixups)
+
+For each new commit group, in dependency order:
+
+\`\`\`bash
+# Stage files
+git add <file1> <file2> ...
+
+# Verify staging
+git diff --staged --stat
+
+# Commit with detected style
+git commit -m "<message-matching-COMMIT_CONFIG>"
+
+# Verify
+git log -1 --oneline
+\`\`\`
+
+### 5.4 Commit Message Generation
+
+**Based on COMMIT_CONFIG from Phase 1:**
+
+\`\`\`
+IF style == SEMANTIC AND language == KOREAN:
+  -> "feat: 로그인 기능 추가"
+  
+IF style == SEMANTIC AND language == ENGLISH:
+  -> "feat: add login feature"
+  
+IF style == PLAIN AND language == KOREAN:
+  -> "로그인 기능 추가"
+  
+IF style == PLAIN AND language == ENGLISH:
+  -> "Add login feature"
+  
+IF style == SHORT:
+  -> "format" / "type fix" / "lint"
+\`\`\`
+
+**VALIDATION before each commit:**
+1. Does message match detected style?
+2. Does language match detected language?
+3. Is it similar to examples from git log?
+
+If ANY check fails -> REWRITE message.
+\`\`\`
+\</execution>
+
+---
+
+## PHASE 6: Verification & Cleanup
+
+<verification>
+### 6.1 Post-Commit Verification
+
+\`\`\`bash
+# Check working directory clean
+git status
+
+# Review new history
+git log --oneline $(git merge-base HEAD main 2>/dev/null || git merge-base HEAD master)..HEAD
+
+# Verify each commit is atomic
+# (mentally check: can each be reverted independently?)
+\`\`\`
+
+### 6.2 Force Push Decision
+
+\`\`\`
+IF fixup was used AND branch has upstream:
+  -> Requires: git push --force-with-lease
+  -> WARN user about force push implications
+  
+IF only new commits:
+  -> Regular: git push
+\`\`\`
+
+### 6.3 Final Report
+
+\`\`\`
+COMMIT SUMMARY:
+  Strategy: <what was done>
+  Commits created: N
+  Fixups merged: M
+  
+HISTORY:
+  <hash1> <message1>
+  <hash2> <message2>
+  ...
+
+NEXT STEPS:
+  - git push [--force-with-lease]
+  - Create PR if ready

+
+## PHASE H1: Determine Search Type
+
+<history_search_type>
+### H1.1 Parse User Request
+
+| User Request | Search Type | Tool |
+|--------------|-------------|------|
+| "when was X added" / "X가 언제 추가됐어" | PICKAXE | \`git log -S\` |
+| "find commits changing X pattern" | REGEX | \`git log -G\` |
+| "who wrote this line" / "이 줄 누가 썼어" | BLAME | \`git blame\` |
+| "when did bug start" / "버그 언제 생겼어" | BISECT | \`git bisect\` |
+| "history of file" / "파일 히스토리" | FILE_LOG | \`git log -- path\` |
+| "find deleted code" / "삭제된 코드 찾기" | PICKAXE_ALL | \`git log -S --all\` |
+
+### H1.2 Extract Search Parameters
+
+\`\`\`
+From user request, identify:
+- SEARCH_TERM: The string/pattern to find
+- FILE_SCOPE: Specific file(s) or entire repo
+- TIME_RANGE: All time or specific period
+- BRANCH_SCOPE: Current branch or --all branches
+\`\`\`
+</history_search_type>
+
+---
+
+## PHASE H2: Execute Search
+
+<history_search_exec>
+### H2.1 Pickaxe Search (git log -S)
+
+**Purpose**: Find commits that ADD or REMOVE a specific string
+
+\`\`\`bash
+# Basic: Find when string was added/removed
+git log -S "searchString" --oneline
+
+# With context (see the actual changes):
+git log -S "searchString" -p
+
+# In specific file:
+git log -S "searchString" -- path/to/file.py
+
+# Across all branches (find deleted code):
+git log -S "searchString" --all --oneline
+
+# With date range:
+git log -S "searchString" --since="2024-01-01" --oneline
+
+# Case insensitive:
+git log -S "searchstring" -i --oneline
+\`\`\`
+
+**Example Use Cases:**
+\`\`\`bash
+# When was this function added?
+git log -S "def calculate_discount" --oneline
+
+# When was this constant removed?
+git log -S "MAX_RETRY_COUNT" --all --oneline
+
+# Find who introduced a bug pattern
+git log -S "== None" -- "*.py" --oneline  # Should be "is None"
+\`\`\`
+
+### H2.2 Regex Search (git log -G)
+
+**Purpose**: Find commits where diff MATCHES a regex pattern
+
+\`\`\`bash
+# Find commits touching lines matching pattern
+git log -G "pattern.*regex" --oneline
+
+# Find function definition changes
+git log -G "def\\s+my_function" --oneline -p
+
+# Find import changes
+git log -G "^import\\s+requests" -- "*.py" --oneline
+
+# Find TODO additions/removals
+git log -G "TODO|FIXME|HACK" --oneline
+\`\`\`
+
+**-S vs -G Difference:**
+\`\`\`
+-S "foo": Finds commits where COUNT of "foo" changed
+-G "foo": Finds commits where DIFF contains "foo"
+
+Use -S for: "when was X added/removed"
+Use -G for: "what commits touched lines containing X"
+\`\`\`
+
+### H2.3 Git Blame
+
+**Purpose**: Line-by-line attribution
+
+\`\`\`bash
+# Basic blame
+git blame path/to/file.py
+
+# Specific line range
+git blame -L 10,20 path/to/file.py
+
+# Show original commit (ignoring moves/copies)
+git blame -C path/to/file.py
+
+# Ignore whitespace changes
+git blame -w path/to/file.py
+
+# Show email instead of name
+git blame -e path/to/file.py
+
+# Output format for parsing
+git blame --porcelain path/to/file.py
+\`\`\`
+
+**Reading Blame Output:**
+\`\`\`
+^abc1234 (Author Name 2024-01-15 10:30:00 +0900 42) code_line_here
+|         |            |                       |    +-- Line content
+|         |            |                       +-- Line number
+|         |            +-- Timestamp
+|         +-- Author
++-- Commit hash (^ means initial commit)
+\`\`\`
+
+### H2.4 Git Bisect (Binary Search for Bugs)
+
+**Purpose**: Find exact commit that introduced a bug
+
+\`\`\`bash
+# Start bisect session
+git bisect start
+
+# Mark current (bad) state
+git bisect bad
+
+# Mark known good commit (e.g., last release)
+git bisect good v1.0.0
+
+# Git checkouts middle commit. Test it, then:
+git bisect good  # if this commit is OK
+git bisect bad   # if this commit has the bug
+
+# Repeat until git finds the culprit commit
+# Git will output: "abc1234 is the first bad commit"
+
+# When done, return to original state
+git bisect reset
+\`\`\`
+
+**Automated Bisect (with test script):**
+\`\`\`bash
+# If you have a test that fails on bug:
+git bisect start
+git bisect bad HEAD
+git bisect good v1.0.0
+git bisect run pytest tests/test_specific.py
+
+# Git runs test on each commit automatically
+# Exits 0 = good, exits 1-127 = bad, exits 125 = skip
+\`\`\`
+
+### H2.5 File History Tracking
+
+\`\`\`bash
+# Full history of a file
+git log --oneline -- path/to/file.py
+
+# Follow file across renames
+git log --follow --oneline -- path/to/file.py
+
+# Show actual changes
+git log -p -- path/to/file.py
+
+# Files that no longer exist
+git log --all --full-history -- "**/deleted_file.py"
+
+# Who changed file most
+git shortlog -sn -- path/to/file.py

+## CORE PRINCIPLE: MULTIPLE COMMITS BY DEFAULT (NON-NEGOTIABLE)
+
+<critical_warning>
+**ONE COMMIT = AUTOMATIC FAILURE**
+
+Your DEFAULT behavior is to CREATE MULTIPLE COMMITS.
+Single commit is a BUG in your logic, not a feature.
+
+**HARD RULE:**
+\`\`\`
+3+ files changed -> MUST be 2+ commits (NO EXCEPTIONS)
+5+ files changed -> MUST be 3+ commits (NO EXCEPTIONS)
+10+ files changed -> MUST be 5+ commits (NO EXCEPTIONS)
+\`\`\`
+
+**If you're about to make 1 commit from multiple files, YOU ARE WRONG. STOP AND SPLIT.**
+
+**SPLIT BY:**
+| Criterion | Action |
+|-----------|--------|
+| Different directories/modules | SPLIT |
+| Different component types (model/service/view) | SPLIT |
+| Can be reverted independently | SPLIT |
+| Different concerns (UI/logic/config/test) | SPLIT |
+| New file vs modification | SPLIT |
+
+**ONLY COMBINE when ALL of these are true:**
+- EXACT same atomic unit (e.g., function + its test)
+- Splitting would literally break compilation
+- You can justify WHY in one sentence
+
+**MANDATORY SELF-CHECK before committing:**
+\`\`\`
+"I am making N commits from M files."
+IF N == 1 AND M > 2:
+  -> WRONG. Go back and split.
+  -> Write down WHY each file must be together.
+  -> If you can't justify, SPLIT.

+| If git log shows... | Use this style |
+|---------------------|----------------|
+| \`feat: xxx\`, \`fix: yyy\` | SEMANTIC |
+| \`Add xxx\`, \`Fix yyy\`, \`xxx 추가\` | PLAIN |
+| \`format\`, \`lint\`, \`typo\` | SHORT |
+| Full sentences | SENTENCE |
+| Mix of above | Use MAJORITY (not semantic by default) |

+### Decision Tree
+
+\`\`\`
+Is this on main/master?
+  YES -> NEW_COMMITS_ONLY, never rewrite
+  NO -> Continue
+
+Are all commits local (not pushed)?
+  YES -> AGGRESSIVE_REWRITE allowed
+  NO -> CAREFUL_REWRITE (warn on force push)
+
+Does change complement existing commit?
+  YES -> FIXUP to that commit
+  NO -> NEW COMMIT
+
+Is history messy?
+  YES + all local -> Consider RESET_REBUILD
+  NO -> Normal flow
+\`\`\`
+
+### Anti-Patterns (AUTOMATIC FAILURE)
+
+1. **NEVER make one giant commit** - 3+ files MUST be 2+ commits
+2. **NEVER default to semantic style** - detect from git log first
+3. **NEVER separate test from implementation** - same commit always
+4. **NEVER group by file type** - group by feature/module
+5. **NEVER rewrite pushed history** without explicit permission
+6. **NEVER leave working directory dirty** - complete all changes
+7. **NEVER skip JUSTIFICATION** - explain why files are grouped
+8. **NEVER use vague grouping reasons** - "related to X" is NOT valid
+
+---
+
+## FINAL CHECK BEFORE EXECUTION (BLOCKING)
+
+\`\`\`
+STOP AND VERIFY - Do not proceed until ALL boxes checked:
+
+[] File count check: N files -> at least ceil(N/3) commits?
+  - 3 files -> min 1 commit
+  - 5 files -> min 2 commits
+  - 10 files -> min 4 commits
+  - 20 files -> min 7 commits
+
+[] Justification check: For each commit with 3+ files, did I write WHY?
+
+[] Directory split check: Different directories -> different commits?
+
+[] Test pairing check: Each test with its implementation?
+
+[] Dependency order check: Foundations before dependents?
+\`\`\`
+
+**HARD STOP CONDITIONS:**
+- Making 1 commit from 3+ files -> **WRONG. SPLIT.**
+- Making 2 commits from 10+ files -> **WRONG. SPLIT MORE.**
+- Can't justify file grouping in one sentence -> **WRONG. SPLIT.**
+- Different directories in same commit (without justification) -> **WRONG. SPLIT.**
+
+---
+
+### Commit Mode
+- One commit for many files -> SPLIT
+- Default to semantic style -> DETECT first
+
+### Rebase Mode
+- Rebase main/master -> NEVER
+- \`--force\` instead of \`--force-with-lease\` -> DANGEROUS
+- Rebase without stashing dirty files -> WILL FAIL
+
+### History Search Mode
+- \`-S\` when \`-G\` is appropriate -> Wrong results
+- Blame without \`-C\` on moved code -> Wrong attribution
+- Bisect without proper good/bad boundaries -> Wasted time`

+\`\`\`bash
+# Find merge-base
+MERGE_BASE=$(git merge-base HEAD main 2>/dev/null || git merge-base HEAD master)
+
+# Start interactive rebase

+   - Read the file
+   - Understand both versions (HEAD vs incoming)
+   - Resolve by editing file
+   - Remove conflict markers (<<<<, ====, >>>>)
+
+3. Stage resolved files:

+4. Continue rebase:
+   git rebase --continue
+
+5. If stuck or confused:
+   git rebase --abort  # Safe rollback

+
+| Situation | Command | Notes |
+|-----------|---------|-------|

+| Need original commits | \`git reflog\` -> \`git reset --hard <hash>\` | Reflog keeps 90 days |
+| Accidentally force-pushed | \`git reflog\` -> coordinate with team | May need to notify others |
+| Lost commits after rebase | \`git fsck --lost-found\` | Nuclear option |

+## PHASE R3: Post-Rebase Verification
+

+# Verify code still works (if tests exist)
+# Run project-specific test command

+### Push Strategy
+
+\`\`\`
+IF branch never pushed:
+  -> git push -u origin <branch>
+
+IF branch already pushed:
+  -> git push --force-with-lease origin <branch>
+  -> ALWAYS use --force-with-lease (not --force)

-## MODE DETECTION (FIRST STEP)
-
-Analyze the user's request to determine operation mode:
-
-| User Request Pattern | Mode | Jump To |
-|---------------------|------|---------|
-| "commit", "커밋", changes to commit | \`COMMIT\` | Phase 0-6 (existing) |
-| "rebase", "리베이스", "squash", "cleanup history" | \`REBASE\` | Phase R1-R4 |
-| "find when", "who changed", "언제 바뀌었", "git blame", "bisect" | \`HISTORY_SEARCH\` | Phase H1-H3 |
-| "smart rebase", "rebase onto" | \`REBASE\` | Phase R1-R4 |
-

----
-
-## PHASE 0: Parallel Context Gathering (MANDATORY FIRST STEP)
-
-<parallel_analysis>
-**Execute ALL of the following commands IN PARALLEL to minimize latency:**
-
-\`\`\`bash
-# Group 1: Current state
-git status
-git diff --staged --stat
-git diff --stat
-
-# Group 2: History context  
-git log -30 --oneline

-
-**Capture these data points simultaneously:**

-2. Recent 30 commit messages for style detection
-3. Branch position relative to main/master
-4. Whether branch has upstream tracking
-5. Commits that would go in PR (local only)
-</parallel_analysis>
-
----
-
-## PHASE 1: Style Detection (BLOCKING - MUST OUTPUT BEFORE PROCEEDING)
-
-<style_detection>
-**THIS PHASE HAS MANDATORY OUTPUT** - You MUST print the analysis result before moving to Phase 2.
-
-### 1.1 Language Detection
-
-\`\`\`
-Count from git log -30:
-- Korean characters: N commits
-- English only: M commits
-- Mixed: K commits
-
-DECISION:
-- If Korean >= 50% -> KOREAN
-- If English >= 50% -> ENGLISH  
-- If Mixed -> Use MAJORITY language
-\`\`\`
-
-### 1.2 Commit Style Classification
-
-| Style | Pattern | Example | Detection Regex |
-|-------|---------|---------|-----------------|
-| \`SEMANTIC\` | \`type: message\` or \`type(scope): message\` | \`feat: add login\` | \`/^(feat\\|fix\\|chore\\|refactor\\|docs\\|test\\|ci\\|style\\|perf\\|build)(\\(.+\\))?:/\` |
-| \`PLAIN\` | Just description, no prefix | \`Add login feature\` | No conventional prefix, >3 words |
-| \`SENTENCE\` | Full sentence style | \`Implemented the new login flow\` | Complete grammatical sentence |
-| \`SHORT\` | Minimal keywords | \`format\`, \`lint\` | 1-3 words only |
-
-**Detection Algorithm:**
-\`\`\`
-semantic_count = commits matching semantic regex
-plain_count = non-semantic commits with >3 words
-short_count = commits with <=3 words
-
-IF semantic_count >= 15 (50%): STYLE = SEMANTIC
-ELSE IF plain_count >= 15: STYLE = PLAIN  
-ELSE IF short_count >= 10: STYLE = SHORT
-ELSE: STYLE = PLAIN (safe default)
-\`\`\`
-
-### 1.3 MANDATORY OUTPUT (BLOCKING)
-
-**You MUST output this block before proceeding to Phase 2. NO EXCEPTIONS.**
-
-\`\`\`
-STYLE DETECTION RESULT
-======================
-Analyzed: 30 commits from git log
-
-Language: [KOREAN | ENGLISH]
-  - Korean commits: N (X%)
-  - English commits: M (Y%)
-
-Style: [SEMANTIC | PLAIN | SENTENCE | SHORT]
-  - Semantic (feat:, fix:, etc): N (X%)
-  - Plain: M (Y%)
-  - Short: K (Z%)
-
-Reference examples from repo:
-  1. "actual commit message from log"
-  2. "actual commit message from log"
-  3. "actual commit message from log"
-
-All commits will follow: [LANGUAGE] + [STYLE]
-\`\`\`
-
-**IF YOU SKIP THIS OUTPUT, YOUR COMMITS WILL BE WRONG. STOP AND REDO.**
-</style_detection>
-
----
-
-## PHASE 2: Branch Context Analysis
-
-<branch_analysis>
-### 2.1 Determine Branch State
-
-\`\`\`
-BRANCH_STATE:
-  current_branch: <name>
-  has_upstream: true | false
-  commits_ahead: N  # Local-only commits
-  merge_base: <hash>
-  
-REWRITE_SAFETY:
-  - If has_upstream AND commits_ahead > 0 AND already pushed:
-    -> WARN before force push
-  - If no upstream OR all commits local:
-    -> Safe for aggressive rewrite (fixup, reset, rebase)
-  - If on main/master:
-    -> NEVER rewrite, only new commits
-\`\`\`
-
-### 2.2 History Rewrite Strategy Decision
-
-\`\`\`
-IF current_branch == main OR current_branch == master:
-  -> STRATEGY = NEW_COMMITS_ONLY
-  -> Never fixup, never rebase
-
-ELSE IF commits_ahead == 0:
-  -> STRATEGY = NEW_COMMITS_ONLY
-  -> No history to rewrite
-
-ELSE IF all commits are local (not pushed):
-  -> STRATEGY = AGGRESSIVE_REWRITE
-  -> Fixup freely, reset if needed, rebase to clean
-
-ELSE IF pushed but not merged:
-  -> STRATEGY = CAREFUL_REWRITE  
-  -> Fixup OK but warn about force push
-\`\`\`
-</branch_analysis>
-
----
-
-## PHASE 3: Atomic Unit Planning (BLOCKING - MUST OUTPUT BEFORE PROCEEDING)
-
-<atomic_planning>
-**THIS PHASE HAS MANDATORY OUTPUT** - You MUST print the commit plan before moving to Phase 4.
-
-### 3.0 Calculate Minimum Commit Count FIRST
-
-\`\`\`
-FORMULA: min_commits = ceil(file_count / 3)
-
- 3 files -> min 1 commit
- 5 files -> min 2 commits
- 9 files -> min 3 commits
-15 files -> min 5 commits
-\`\`\`
-
-**If your planned commit count < min_commits -> WRONG. SPLIT MORE.**
-
-### 3.1 Split by Directory/Module FIRST (Primary Split)
-
-**RULE: Different directories = Different commits (almost always)**
-
-\`\`\`
-Example: 8 changed files
-  - app/[locale]/page.tsx
-  - app/[locale]/layout.tsx
-  - components/demo/browser-frame.tsx
-  - components/demo/shopify-full-site.tsx
-  - components/pricing/pricing-table.tsx
-  - e2e/navbar.spec.ts
-  - messages/en.json
-  - messages/ko.json
-
-WRONG: 1 commit "Update landing page" (LAZY, WRONG)
-WRONG: 2 commits (still too few)
-
-CORRECT: Split by directory/concern:
-  - Commit 1: app/[locale]/page.tsx + layout.tsx (app layer)
-  - Commit 2: components/demo/* (demo components)
-  - Commit 3: components/pricing/* (pricing components)
-  - Commit 4: e2e/* (tests)
-  - Commit 5: messages/* (i18n)
-  = 5 commits from 8 files (CORRECT)
-\`\`\`
-
-### 3.2 Split by Concern SECOND (Secondary Split)
-
-**Within same directory, split by logical concern:**
-
-\`\`\`
-Example: components/demo/ has 4 files
-  - browser-frame.tsx (UI frame)
-  - shopify-full-site.tsx (specific demo)
-  - review-dashboard.tsx (NEW - specific demo)
-  - tone-settings.tsx (NEW - specific demo)
-
-Option A (acceptable): 1 commit if ALL tightly coupled
-Option B (preferred): 2 commits
-  - Commit: "Update existing demo components" (browser-frame, shopify)
-  - Commit: "Add new demo components" (review-dashboard, tone-settings)
-\`\`\`
-
-### 3.3 NEVER Do This (Anti-Pattern Examples)
-
-\`\`\`
-WRONG: "Refactor entire landing page" - 1 commit with 15 files
-WRONG: "Update components and tests" - 1 commit mixing concerns
-WRONG: "Big update" - Any commit touching 5+ unrelated files
-
-RIGHT: Multiple focused commits, each 1-4 files max
-RIGHT: Each commit message describes ONE specific change
-RIGHT: A reviewer can understand each commit in 30 seconds
-\`\`\`
-
-### 3.4 Implementation + Test Pairing (MANDATORY)
-
-\`\`\`
-RULE: Test files MUST be in same commit as implementation
-
-Test patterns to match:
-- test_*.py <-> *.py
-- *_test.py <-> *.py
-- *.test.ts <-> *.ts
-- *.spec.ts <-> *.ts
-- __tests__/*.ts <-> *.ts
-- tests/*.py <-> src/*.py
-\`\`\`
-
-### 3.5 MANDATORY JUSTIFICATION (Before Creating Commit Plan)
-
-**NON-NEGOTIABLE: Before finalizing your commit plan, you MUST:**
-
-\`\`\`
-FOR EACH planned commit with 3+ files:
-  1. List all files in this commit
-  2. Write ONE sentence explaining why they MUST be together
-  3. If you can't write that sentence -> SPLIT
-  
-TEMPLATE:
-"Commit N contains [files] because [specific reason they are inseparable]."
-
-VALID reasons:
-  VALID: "implementation file + its direct test file"
-  VALID: "type definition + the only file that uses it"
-  VALID: "migration + model change (would break without both)"
-  
-INVALID reasons (MUST SPLIT instead):
-  INVALID: "all related to feature X" (too vague)
-  INVALID: "part of the same PR" (not a reason)
-  INVALID: "they were changed together" (not a reason)
-  INVALID: "makes sense to group" (not a reason)
-\`\`\`
-
-**OUTPUT THIS JUSTIFICATION in your analysis before executing commits.**
-
-### 3.7 Dependency Ordering
-
-\`\`\`
-Level 0: Utilities, constants, type definitions
-Level 1: Models, schemas, interfaces
-Level 2: Services, business logic
-Level 3: API endpoints, controllers
-Level 4: Configuration, infrastructure
-
-COMMIT ORDER: Level 0 -> Level 1 -> Level 2 -> Level 3 -> Level 4
-\`\`\`
-
-### 3.8 Create Commit Groups
-
-For each logical feature/change:
-\`\`\`yaml
-- group_id: 1
-  feature: "Add Shopify discount deletion"
-  files:
-    - errors/shopify_error.py
-    - types/delete_input.py
-    - mutations/update_contract.py
-    - tests/test_update_contract.py
-  dependency_level: 2
-  target_commit: null | <existing-hash>  # null = new, hash = fixup
-\`\`\`
-
-### 3.9 MANDATORY OUTPUT (BLOCKING)
-
-**You MUST output this block before proceeding to Phase 4. NO EXCEPTIONS.**
-
-\`\`\`
-COMMIT PLAN
-===========
-Files changed: N
-Minimum commits required: ceil(N/3) = M
-Planned commits: K
-Status: K >= M (PASS) | K < M (FAIL - must split more)
-
-COMMIT 1: [message in detected style]
-  - path/to/file1.py
-  - path/to/file1_test.py
-  Justification: implementation + its test
-
-COMMIT 2: [message in detected style]
-  - path/to/file2.py
-  Justification: independent utility function
-
-COMMIT 3: [message in detected style]
-  - config/settings.py
-  - config/constants.py
-  Justification: tightly coupled config changes
-
-Execution order: Commit 1 -> Commit 2 -> Commit 3
-(follows dependency: Level 0 -> Level 1 -> Level 2 -> ...)
-\`\`\`
-
-**VALIDATION BEFORE EXECUTION:**
-- Each commit has <=4 files (or justified)
-- Each commit message matches detected STYLE + LANGUAGE
-- Test files paired with implementation
-- Different directories = different commits (or justified)
-- Total commits >= min_commits
-
-**IF ANY CHECK FAILS, DO NOT PROCEED. REPLAN.**

-## PHASE 4: Commit Strategy Decision
-
-<strategy_decision>
-### 4.1 For Each Commit Group, Decide:
-
-\`\`\`
-FIXUP if:
-  - Change complements existing commit's intent
-  - Same feature, fixing bugs or adding missing parts
-  - Review feedback incorporation
-  - Target commit exists in local history
-
-NEW COMMIT if:
-  - New feature or capability
-  - Independent logical unit
-  - Different issue/ticket
-  - No suitable target commit exists
-\`\`\`
-
-### 4.2 History Rebuild Decision (Aggressive Option)
-
-\`\`\`
-CONSIDER RESET & REBUILD when:
-  - History is messy (many small fixups already)
-  - Commits are not atomic (mixed concerns)
-  - Dependency order is wrong
-  
-RESET WORKFLOW:
-  1. git reset --soft $(git merge-base HEAD main)
-  2. All changes now staged
-  3. Re-commit in proper atomic units
-  4. Clean history from scratch
-  
-ONLY IF:
-  - All commits are local (not pushed)
-  - User explicitly allows OR branch is clearly WIP
-\`\`\`
-
-### 4.3 Final Plan Summary
-
-\`\`\`yaml
-EXECUTION_PLAN:
-  strategy: FIXUP_THEN_NEW | NEW_ONLY | RESET_REBUILD

-## PHASE 5: Commit Execution
-
-<execution>
-### 5.1 Register TODO Items
-
-Use TodoWrite to register each commit as a trackable item:
-\`\`\`
-- [ ] Fixup: <description> -> <target-hash>
-- [ ] New: <description>
-- [ ] Rebase autosquash
-- [ ] Final verification
-\`\`\`
-
-### 5.2 Fixup Commits (If Any)
-
-\`\`\`bash
-# Stage files for each fixup
-git add <files>
-git commit --fixup=<target-hash>
-
-# Repeat for all fixups...
-
-# Single autosquash rebase at the end
-MERGE_BASE=$(git merge-base HEAD main 2>/dev/null || git merge-base HEAD master)
-GIT_SEQUENCE_EDITOR=: git rebase -i --autosquash $MERGE_BASE
-\`\`\`
-
-### 5.3 New Commits (After Fixups)
-
-For each new commit group, in dependency order:
-
-\`\`\`bash
-# Stage files
-git add <file1> <file2> ...
-
-# Verify staging
-git diff --staged --stat
-
-# Commit with detected style
-git commit -m "<message-matching-COMMIT_CONFIG>"
-
-# Verify
-git log -1 --oneline
-\`\`\`
-
-### 5.4 Commit Message Generation
-
-**Based on COMMIT_CONFIG from Phase 1:**
-
-\`\`\`
-IF style == SEMANTIC AND language == KOREAN:
-  -> "feat: 로그인 기능 추가"
-  
-IF style == SEMANTIC AND language == ENGLISH:
-  -> "feat: add login feature"
-  
-IF style == PLAIN AND language == KOREAN:
-  -> "로그인 기능 추가"
-  
-IF style == PLAIN AND language == ENGLISH:
-  -> "Add login feature"
-  
-IF style == SHORT:
-  -> "format" / "type fix" / "lint"
-\`\`\`
-
-**VALIDATION before each commit:**
-1. Does message match detected style?
-2. Does language match detected language?
-3. Is it similar to examples from git log?
-
-If ANY check fails -> REWRITE message.
-\`\`\`
-\</execution>
-
----
-
-## PHASE 6: Verification & Cleanup
-
-<verification>
-### 6.1 Post-Commit Verification
-
-\`\`\`bash
-# Check working directory clean
-git status
-
-# Review new history
-git log --oneline $(git merge-base HEAD main 2>/dev/null || git merge-base HEAD master)..HEAD
-
-# Verify each commit is atomic
-# (mentally check: can each be reverted independently?)
-\`\`\`
-
-### 6.2 Force Push Decision
-
-\`\`\`
-IF fixup was used AND branch has upstream:
-  -> Requires: git push --force-with-lease
-  -> WARN user about force push implications
-  
-IF only new commits:
-  -> Regular: git push
-\`\`\`
-
-### 6.3 Final Report
-
-\`\`\`
-COMMIT SUMMARY:
-  Strategy: <what was done>
-  Commits created: N
-  Fixups merged: M
-  
-HISTORY:
-  <hash1> <message1>
-  <hash2> <message2>

-
-NEXT STEPS:
-  - git push [--force-with-lease]

-## Quick Reference
-
-### Style Detection Cheat Sheet
-
-| If git log shows... | Use this style |
-|---------------------|----------------|
-| \`feat: xxx\`, \`fix: yyy\` | SEMANTIC |
-| \`Add xxx\`, \`Fix yyy\`, \`xxx 추가\` | PLAIN |
-| \`format\`, \`lint\`, \`typo\` | SHORT |
-| Full sentences | SENTENCE |
-| Mix of above | Use MAJORITY (not semantic by default) |
-
-### Decision Tree
-
-\`\`\`
-Is this on main/master?
-  YES -> NEW_COMMITS_ONLY, never rewrite
-  NO -> Continue
-
-Are all commits local (not pushed)?
-  YES -> AGGRESSIVE_REWRITE allowed
-  NO -> CAREFUL_REWRITE (warn on force push)
-
-Does change complement existing commit?
-  YES -> FIXUP to that commit
-  NO -> NEW COMMIT
-
-Is history messy?
-  YES + all local -> Consider RESET_REBUILD
-  NO -> Normal flow
-\`\`\`
-
-### Anti-Patterns (AUTOMATIC FAILURE)
-
-1. **NEVER make one giant commit** - 3+ files MUST be 2+ commits
-2. **NEVER default to semantic commits** - detect from git log first
-3. **NEVER separate test from implementation** - same commit always
-4. **NEVER group by file type** - group by feature/module
-5. **NEVER rewrite pushed history** without explicit permission
-6. **NEVER leave working directory dirty** - complete all changes
-7. **NEVER skip JUSTIFICATION** - explain why files are grouped
-8. **NEVER use vague grouping reasons** - "related to X" is NOT valid
-
----
-
-## FINAL CHECK BEFORE EXECUTION (BLOCKING)
-
-\`\`\`
-STOP AND VERIFY - Do not proceed until ALL boxes checked:
-
-[] File count check: N files -> at least ceil(N/3) commits?
-  - 3 files -> min 1 commit
-  - 5 files -> min 2 commits
-  - 10 files -> min 4 commits
-  - 20 files -> min 7 commits
-
-[] Justification check: For each commit with 3+ files, did I write WHY?
-
-[] Directory split check: Different directories -> different commits?
-
-[] Test pairing check: Each test with its implementation?
-
-[] Dependency order check: Foundations before dependents?
-\`\`\`
-
-**HARD STOP CONDITIONS:**
-- Making 1 commit from 3+ files -> **WRONG. SPLIT.**
-- Making 2 commits from 10+ files -> **WRONG. SPLIT MORE.**
-- Can't justify file grouping in one sentence -> **WRONG. SPLIT.**
-- Different directories in same commit (without justification) -> **WRONG. SPLIT.**

-# REBASE MODE (Phase R1-R4)
-
-## PHASE R1: Rebase Context Analysis
-
-<rebase_context>
-### R1.1 Parallel Information Gathering
-
-\`\`\`bash
-# Execute ALL in parallel
-git branch --show-current
-git log --oneline -20
-git merge-base HEAD main 2>/dev/null || git merge-base HEAD master
-git rev-parse --abbrev-ref @{upstream} 2>/dev/null || echo "NO_UPSTREAM"
-git status --porcelain
-git stash list
-\`\`\`
-
-### R1.2 Safety Assessment
-
-| Condition | Risk Level | Action |
-|-----------|------------|--------|
-| On main/master | CRITICAL | **ABORT** - never rebase main |
-| Dirty working directory | WARNING | Stash first: \`git stash push -m "pre-rebase"\` |
-| Pushed commits exist | WARNING | Will require force-push; confirm with user |
-| All commits local | SAFE | Proceed freely |
-| Upstream diverged | WARNING | May need \`--onto\` strategy |
-
-### R1.3 Determine Rebase Strategy
-
-\`\`\`
-USER REQUEST -> STRATEGY:
-
-"squash commits" / "cleanup" / "정리"
-  -> INTERACTIVE_SQUASH
-
-"rebase on main" / "update branch" / "메인에 리베이스"
-  -> REBASE_ONTO_BASE
-
-"autosquash" / "apply fixups"
-  -> AUTOSQUASH
-
-"reorder commits" / "커밋 순서"
-  -> INTERACTIVE_REORDER
-
-"split commit" / "커밋 분리"
-  -> INTERACTIVE_EDIT
-\`\`\`
-</rebase_context>
-
----
-
-## PHASE R2: Rebase Execution
-
-<rebase_execution>
-### R2.1 Interactive Rebase (Squash/Reorder)
-
-\`\`\`bash
-# Find merge-base
-MERGE_BASE=$(git merge-base HEAD main 2>/dev/null || git merge-base HEAD master)
-
-# Start interactive rebase
-# NOTE: Cannot use -i interactively. Use GIT_SEQUENCE_EDITOR for automation.
-
-# For SQUASH (combine all into one):
-git reset --soft $MERGE_BASE
-git commit -m "Combined: <summarize all changes>"
-
-# For SELECTIVE SQUASH (keep some, squash others):
-# Use fixup approach - mark commits to squash, then autosquash
-\`\`\`
-
-### R2.2 Autosquash Workflow
-
-\`\`\`bash
-# When you have fixup! or squash! commits:
-MERGE_BASE=$(git merge-base HEAD main 2>/dev/null || git merge-base HEAD master)
-GIT_SEQUENCE_EDITOR=: git rebase -i --autosquash $MERGE_BASE
-
-# The GIT_SEQUENCE_EDITOR=: trick auto-accepts the rebase todo
-# Fixup commits automatically merge into their targets
-\`\`\`
-
-### R2.3 Rebase Onto (Branch Update)
-
-\`\`\`bash
-# Scenario: Your branch is behind main, need to update
-
-# Simple rebase onto main:
-git fetch origin
-git rebase origin/main
-
-# Complex: Move commits to different base
-# git rebase --onto <newbase> <oldbase> <branch>
-git rebase --onto origin/main $(git merge-base HEAD origin/main) HEAD
-\`\`\`
-
-### R2.4 Handling Conflicts
-
-\`\`\`
-CONFLICT DETECTED -> WORKFLOW:
-
-1. Identify conflicting files:
-   git status | grep "both modified"
-
-2. For each conflict:
-   - Read the file
-   - Understand both versions (HEAD vs incoming)
-   - Resolve by editing file
-   - Remove conflict markers (<<<<, ====, >>>>)
-
-3. Stage resolved files:
-   git add <resolved-file>
-
-4. Continue rebase:
-   git rebase --continue
-
-5. If stuck or confused:
-   git rebase --abort  # Safe rollback
-\`\`\`
-
-### R2.5 Recovery Procedures
-
-| Situation | Command | Notes |
-|-----------|---------|-------|
-| Rebase going wrong | \`git rebase --abort\` | Returns to pre-rebase state |
-| Need original commits | \`git reflog\` -> \`git reset --hard <hash>\` | Reflog keeps 90 days |
-| Accidentally force-pushed | \`git reflog\` -> coordinate with team | May need to notify others |
-| Lost commits after rebase | \`git fsck --lost-found\` | Nuclear option |
-</rebase_execution>
-
----
-
-## PHASE R3: Post-Rebase Verification
-
-<rebase_verify>
-\`\`\`bash
-# Verify clean state
-git status
-
-# Check new history
-git log --oneline $(git merge-base HEAD main 2>/dev/null || git merge-base HEAD master)..HEAD
-
-# Verify code still works (if tests exist)
-# Run project-specific test command
-
-# Compare with pre-rebase if needed
-git diff ORIG_HEAD..HEAD --stat
-\`\`\`
-
-### Push Strategy
-
-\`\`\`
-IF branch never pushed:
-  -> git push -u origin <branch>
-
-IF branch already pushed:
-  -> git push --force-with-lease origin <branch>
-  -> ALWAYS use --force-with-lease (not --force)

-# HISTORY SEARCH MODE (Phase H1-H3)
-
-## PHASE H1: Determine Search Type
-
-<history_search_type>
-### H1.1 Parse User Request
-
-| User Request | Search Type | Tool |
-|--------------|-------------|------|
-| "when was X added" / "X가 언제 추가됐어" | PICKAXE | \`git log -S\` |
-| "find commits changing X pattern" | REGEX | \`git log -G\` |
-| "who wrote this line" / "이 줄 누가 썼어" | BLAME | \`git blame\` |
-| "when did bug start" / "버그 언제 생겼어" | BISECT | \`git bisect\` |
-| "history of file" / "파일 히스토리" | FILE_LOG | \`git log -- path\` |
-| "find deleted code" / "삭제된 코드 찾기" | PICKAXE_ALL | \`git log -S --all\` |
-
-### H1.2 Extract Search Parameters
-
-\`\`\`
-From user request, identify:
-- SEARCH_TERM: The string/pattern to find
-- FILE_SCOPE: Specific file(s) or entire repo
-- TIME_RANGE: All time or specific period
-- BRANCH_SCOPE: Current branch or --all branches
-\`\`\`
-</history_search_type>
-
----
-
-## PHASE H2: Execute Search
-
-<history_search_exec>
-### H2.1 Pickaxe Search (git log -S)
-
-**Purpose**: Find commits that ADD or REMOVE a specific string
-
-\`\`\`bash
-# Basic: Find when string was added/removed
-git log -S "searchString" --oneline
-
-# With context (see the actual changes):
-git log -S "searchString" -p
-
-# In specific file:
-git log -S "searchString" -- path/to/file.py
-
-# Across all branches (find deleted code):
-git log -S "searchString" --all --oneline
-
-# With date range:
-git log -S "searchString" --since="2024-01-01" --oneline
-
-# Case insensitive:
-git log -S "searchstring" -i --oneline
-\`\`\`
-
-**Example Use Cases:**
-\`\`\`bash
-# When was this function added?
-git log -S "def calculate_discount" --oneline
-
-# When was this constant removed?
-git log -S "MAX_RETRY_COUNT" --all --oneline
-
-# Find who introduced a bug pattern
-git log -S "== None" -- "*.py" --oneline  # Should be "is None"
-\`\`\`
-
-### H2.2 Regex Search (git log -G)
-
-**Purpose**: Find commits where diff MATCHES a regex pattern
-
-\`\`\`bash
-# Find commits touching lines matching pattern
-git log -G "pattern.*regex" --oneline
-
-# Find function definition changes
-git log -G "def\\s+my_function" --oneline -p
-
-# Find import changes
-git log -G "^import\\s+requests" -- "*.py" --oneline
-
-# Find TODO additions/removals
-git log -G "TODO|FIXME|HACK" --oneline
-\`\`\`
-
-**-S vs -G Difference:**
-\`\`\`
--S "foo": Finds commits where COUNT of "foo" changed
--G "foo": Finds commits where DIFF contains "foo"
-
-Use -S for: "when was X added/removed"
-Use -G for: "what commits touched lines containing X"
-\`\`\`
-
-### H2.3 Git Blame
-
-**Purpose**: Line-by-line attribution
-
-\`\`\`bash
-# Basic blame
-git blame path/to/file.py
-
-# Specific line range
-git blame -L 10,20 path/to/file.py
-
-# Show original commit (ignoring moves/copies)
-git blame -C path/to/file.py
-
-# Ignore whitespace changes
-git blame -w path/to/file.py
-
-# Show email instead of name
-git blame -e path/to/file.py
-
-# Output format for parsing
-git blame --porcelain path/to/file.py
-\`\`\`
-
-**Reading Blame Output:**
-\`\`\`
-^abc1234 (Author Name 2024-01-15 10:30:00 +0900 42) code_line_here
-|         |            |                       |    +-- Line content
-|         |            |                       +-- Line number
-|         |            +-- Timestamp
-|         +-- Author
-+-- Commit hash (^ means initial commit)
-\`\`\`
-
-### H2.4 Git Bisect (Binary Search for Bugs)
-
-**Purpose**: Find exact commit that introduced a bug
-
-\`\`\`bash
-# Start bisect session
-git bisect start
-
-# Mark current (bad) state
-git bisect bad
-
-# Mark known good commit (e.g., last release)
-git bisect good v1.0.0
-
-# Git checkouts middle commit. Test it, then:
-git bisect good  # if this commit is OK
-git bisect bad   # if this commit has the bug
-
-# Repeat until git finds the culprit commit
-# Git will output: "abc1234 is the first bad commit"
-
-# When done, return to original state
-git bisect reset
-\`\`\`
-
-**Automated Bisect (with test script):**
-\`\`\`bash
-# If you have a test that fails on bug:
-git bisect start
-git bisect bad HEAD
-git bisect good v1.0.0
-git bisect run pytest tests/test_specific.py
-
-# Git runs test on each commit automatically
-# Exits 0 = good, exits 1-127 = bad, exits 125 = skip
-\`\`\`
-
-### H2.5 File History Tracking
-
-\`\`\`bash
-# Full history of a file
-git log --oneline -- path/to/file.py
-
-# Follow file across renames
-git log --follow --oneline -- path/to/file.py
-
-# Show actual changes
-git log -p -- path/to/file.py
-
-# Files that no longer exist
-git log --all --full-history -- "**/deleted_file.py"
-
-# Who changed file most
-git shortlog -sn -- path/to/file.py
-\`\`\`
-</history_search_exec>
