Linear Workflow

Linear Workflow Skill

Execute feature implementation following the standardized Linear workflow for spec-driven development.

When to Use

Use this skill when implementing a Linear issue (e.g., PROJ-18, PROJ-19) that has well-defined tasks from a spec.

Workflow Steps

1. Initialize Linear Issue

Action: Update the Linear issue to "In Progress"

Use: mcp__plugin_linear_linear__update_issue
Parameters:
  - id: {ISSUE_ID}
  - state: "In Progress"

2. Setup Task Tracking

Action: Create TodoWrite list for all tasks in the issue

Use: TodoWrite tool
Include:
  - All test tasks (e.g., T045, T046)
  - All implementation tasks (e.g., T047-T052)
  - Mark first task as "in_progress"

3. Follow TDD Approach

For each task group:

a. Write Tests First (Tasks like T045, T046)

• Create test files
• Verify tests would fail without implementation
• Mark test tasks as completed in TodoWrite

b. Implement Code (Tasks like T047-T048)

• Create implementation files
• Mark implementation tasks as completed in TodoWrite

c. Pause for Xcode Project Updates

• If new files created, STOP and ask user to add them to Xcode
• Wait for confirmation before proceeding

d. Run Tests (Task like T052)

• Run full test suite: xcodebuild -project ... test
• Verify all tests pass (e.g., "126/126 passing")
• Check specific test suites passed (e.g., "OnboardingStateTests: 4/4 passed")
• Mark test verification task as completed

4. Prepare Commit

Action: Draft commit message following Linear format

Format:
{Brief description (T{start}-T{end})}. Completes {ISSUE_ID}

{Detailed body with:**
- **Test Files Created (T{X}-T{Y}):**
  - File descriptions with test counts

- **Implementation Files Created (T{X}):**
  - File descriptions with features

- **Files Modified:**
  - What changed and why (with task references)

- **Test Results (T{X}):**
  - X/X unit tests passing (added Y tests)
  - X/X UI tests passing
  - Specific test suite results

CRITICAL: "Completes {ISSUE_ID}" MUST be at the END of the title line, NOT in the body

5. Get Approval

Action: Present commit message to user

Say: "Please review and approve this commit message before I proceed with the commit."
Wait for user approval before committing

6. Commit Changes

Action: Commit with approved message

Use: git add -A && git commit -m "$(cat <<'EOF'
{approved commit message}
EOF
)"

7. Update Linear Issue Status

Action: Mark issue as "In Review" (or "Done" if no manual testing)

Use: mcp__plugin_linear_linear__update_issue
Parameters:
  - id: {ISSUE_ID}
  - state: "In Review"  // or "Done" if fully complete

8. Update tasks.md

Action: Mark completed tasks in spec tasks.md file

Change: [ ] T{X} -> [x] T{X}
For all completed tasks

Then commit:
git add specs/{spec-name}/tasks.md && \
git commit -m "Update tasks.md: Mark T{X}-T{Y} as complete ({ISSUE_ID})"

Example Usage

User: "Use the linear workflow to execute tasks in PROJ-20"

Claude:
1. Updates PROJ-20 to "In Progress"
2. Creates TodoWrite with T066-T072
3. Implements T066 (tests), T067 (code), etc.
4. Pauses for Xcode file additions
5. Runs tests, verifies all pass
6. Drafts commit message with "Completes PROJ-20" at end of title
7. Gets user approval
8. Commits changes
9. Updates PROJ-20 to "In Review"
10. Updates tasks.md with completed tasks

Commit Message Examples

✅ CORRECT Format

Phase 5: Implement location permission screen (T045-T052). Completes PROJ-18

{body text}

❌ INCORRECT Format

[PROJ-18] Phase 5: Implement location permission screen (T045-T052)

{body text}
Completes PROJ-18

Key Principles

1. Always TDD: Tests before implementation
2. Pause for Xcode: Never assume files are added automatically
3. Get Approval: Always show commit message before committing
4. Linear Format: "Completes {ISSUE-ID}" at END of title
5. Track Progress: Use TodoWrite throughout
6. Update Status: Keep Linear issue status current
7. Document Tasks: Update tasks.md after completion
