Linear Commit

Make incremental commits during development, linking to Linear issue and syncing progress.

Usage: /yux-linear-commit [--no-push] [description]

Input

• description: Reference for commit message generation (Claude auto-generates)
• --no-push: Skip auto-push after commit

Workflow

Step 1: Detect Context

1. Get branch: git branch --show-current
2. Extract LIN-xxx from branch name. If not on Linear branch -> prompt /yux-linear-start
3. Fetch issue via mcp__linear__get_issue(id: "LIN-xxx")
4. Check changes: git status --porcelain
   • If changes exist -> continue to Step 2
   • If clean -> run Clean Status Check below, then exit (do NOT continue to Step 2)

Clean Status Check (no uncommitted changes)

1. Run git log origin/main..HEAD --oneline. If empty (no commits on branch), say "No uncommitted changes and no commits on this branch yet" and exit.
2. Get last commit: git log -1 --format="%H %s" (full hash + subject)
3. Fetch comments: mcp__linear__list_comments(issueId: "<uuid from step 1.3>")
4. Search comment bodies for the last commit hash substring
5. If found (commit already synced):

   === No Changes ===
   
   Last commit:  <short-hash> - <subject> (synced to Linear ✓)
   Issue:        LIN-xxx - <title> (<status>)
   
   Next: keep coding, or /yux-linear-pr when ready
   

6. If not found (commit not synced): Use AskUserQuestion: "Last commit <short-hash> - <subject> hasn't been synced to Linear yet. Sync now?"
   • Yes -> execute Step 9 (Sync to Linear) for this commit, then show summary
   • No -> show summary with "Synced: skipped"

Step 2: Display Changes

Categorize files (new/modified/deleted), flag sensitive files (.env, credentials).

Step 3: File Selection

Use AskUserQuestion: commit all, select specific, exclude specific, or cancel.

Step 4: Atomic Check

Analyze if changes should be split. If multiple unrelated groups detected, suggest splitting. If user declines to split, proceed with all changes in a single commit.

Step 5: Generate Commit Message

Auto-determine from diff analysis:

• Emoji + type + scope + subject
• What/Why/Refs sections
• Language: detect from user input, default to English
• Format: <emoji> <type>(<scope>): <subject>
• Include Refs: LIN-xxx and Co-Authored-By line

Show for confirmation. User can modify or approve.

Step 6: Execute

git add <files>
git commit -m "<message>"

Step 7: Auto-Push (default on)

git push origin HEAD

If fails:

• Non-fast-forward: suggest git pull --rebase origin HEAD, then retry push
• Auth/network error: inform user and stop (commit is still saved locally)

Skip if --no-push flag passed.

Step 8: Update Task State

If .claude/linear-tasks.json exists, update last_active_at.

Step 9: Sync to Linear (Required)

mcp__linear__create_comment(
  issueId: "<uuid>",
  body: "**Commit**: `<hash>`\n```\n<message>\n```\nFiles: <count>"
)

Step 10: Summary

=== Commit Synced ===

Commit:   abc1234 - feat(auth): add JWT token validation
Branch:   feat/LIN-456-user-auth
Files:    3 changed (+45, -12)
Push:     origin/feat/LIN-456-user-auth
Linear:   Comment posted to LIN-456

Next: /yux-linear-pr when ready for review
