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:

- 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

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

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

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

PHASE 5: Commit Execution

- [ ] Fixup: <description> -> <target-hash>
- [ ] New: <description>
- [ ] Rebase autosquash
- [ ] Final verification

# 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

# 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

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"

{ "git_master": { "commit_footer": false, "include_co_authored_by": false } }

PHASE 6: Verification & Cleanup

# 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?)

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

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

Quick Reference

Style Detection Cheat Sheet

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

# 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

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

PHASE R2: Rebase Execution

# 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

# 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

# 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

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

# 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

</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

# 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"

# 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 "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"

# 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
