Linear SOP Skill

Purpose

Guide consistent Linear ticket management. Provides evidence templates for the mandatory dev/staging/UAT evidence policy.

When This Skill Applies

Invoke this skill when:

Creating new Linear issues
Updating ticket status
Attaching evidence to tickets
Parsing acceptance criteria
Working with UUIDs and issue IDs

Linear MCP Tools

Reading Issues

# Get issue by identifier
mcp__{{MCP_LINEAR_SERVER}}__get_issue({ id: "{{TICKET_PREFIX}}-459" })

# List issues with filters
mcp__{{MCP_LINEAR_SERVER}}__list_issues({
  team: "{{PROJECT_TEAM_NAME}}",
  state: "In Progress",
  assignee: "me",
})

Creating Issues

mcp__{{MCP_LINEAR_SERVER}}__create_issue({
  title: "feat(scope): description",
  team: "{{PROJECT_TEAM_NAME}}",
  description: "## Summary\n\n...",
  labels: ["feature", "sprint-1"],
  parentId: "parent-uuid",  // Optional - for sub-issues
})

Updating Issues

mcp__{{MCP_LINEAR_SERVER}}__update_issue({
  id: "{{TICKET_PREFIX}}-459",
  state: "Done",
})

Adding Comments

mcp__{{MCP_LINEAR_SERVER}}__create_comment({
  issueId: "{{TICKET_PREFIX}}-459",
  body: "**Dev Evidence**\n\n...",
})

Evidence Policy (MUST)

Every issue requires evidence at each phase:

Phase	Required?	Content
Dev	MUST	Implementation proof
Staging	MUST	UAT validation (or N/A)
Done	MUST	Final verification

Evidence Templates

Dev Evidence Template

**Dev Evidence**

**PR**: https://github.com/{{ORG_NAME}}/{{REPO_NAME}}/pull/XXX
**Commit**: [short-hash]
**Branch**: {{TICKET_PREFIX}}-XXX-description

**Implementation:**

- [x] Feature implemented
- [x] Tests passing
- [x] Lint passing

**Verification:**

\`\`\`bash
yarn ci:validate

# Output: All checks passed

\`\`\`

Staging/UAT Evidence Template

**Staging Evidence**

**Environment**: Pop OS dev server
**URL**: http://pop-os:3000

**Validation Steps:**

1. Deployed to staging: [timestamp]
2. Smoke test passed: [yes/no]
3. Feature verified: [description]

**UAT Status:** [Passed/Pending/N/A]

If N/A, reason: [e.g., "Dev tooling only - no user-facing changes"]

Done Evidence Template

**Done Evidence**

**PR Merged**: https://github.com/{{ORG_NAME}}/{{REPO_NAME}}/pull/XXX
**Merge Commit**: [hash]

**Final Checklist:**

- [x] All acceptance criteria met
- [x] Documentation updated (if applicable)
- [x] No regressions detected

Acceptance Criteria Parsing

When reading issue descriptions, extract ACs:

## Acceptance Criteria

- [ ] User can perform action X
- [ ] System responds with Y
- [ ] Error handling for Z

Convert to testable checklist:

const acceptanceCriteria = [
  { criterion: "User can perform action X", verified: false },
  { criterion: "System responds with Y", verified: false },
  { criterion: "Error handling for Z", verified: false },
];

Status Workflow

Backlog -> Ready -> In Progress -> Testing -> Ready for Review -> Done

GitHub-Linear Auto-Sync

Tickets referenced in commit messages (e.g., [{{TICKET_PREFIX}}-123]) automatically move to Done when the PR merges. Child stories not referenced in any commit message must be manually closed after merge.

Best practice: Reference Feature-level tickets in commit messages. After merge, manually close orphaned child stories that weren't referenced.

Status Update Guidelines

From	To	When
Backlog	Ready	Sprint planning
Ready	In Progress	Work starts
In Progress	Testing	PR created
Testing	Ready for Review	Tests pass, UAT complete
Ready for Review	Done	POPM approval or auto-sync via PR merge

UUID Handling

Linear uses UUIDs internally. When working with APIs:

// Issue identifiers (human-readable)
const issueId = "{{TICKET_PREFIX}}-459";

// UUIDs (API operations)
const uuid = "ef6a5fa0-2b46-417f-8266-dea2d187b10a";

// Get UUID from identifier via MCP tool
// mcp__{{MCP_LINEAR_SERVER}}__get_issue({ id: "{{TICKET_PREFIX}}-459" })
// Returns issue object with .id property containing UUID

Common Operations

Link PR to Issue

PRs are automatically linked when:

Branch name contains {{TICKET_PREFIX}}-XXX
PR title contains [{{TICKET_PREFIX}}-XXX]

Create Sub-Issue

mcp__{{MCP_LINEAR_SERVER}}__create_issue({
  title: "Sub-task description",
  team: "{{PROJECT_TEAM_NAME}}",
  parentId: "parent-issue-uuid",
})

Query by Label

mcp__{{MCP_LINEAR_SERVER}}__list_issues({
  label: "sprint-1",
  team: "{{PROJECT_TEAM_NAME}}",
})
