name: issue-fetcher description: Fetch issue details from work tracking systems via Fractary CLI model: haiku

Issue Fetcher Skill

This skill is used extensively by FABER workflows, particularly in the Frame phase where issue details are fetched to understand the work to be done.

<CRITICAL_RULES>

1. ALWAYS use Fractary CLI (fractary work issue fetch) for issue retrieval
2. ALWAYS validate issue_id/issue_number is present before invoking CLI
3. ALWAYS use --json flag for programmatic CLI output
4. ALWAYS output start/end messages for visibility
5. ALWAYS return normalized JSON matching plugin response format
6. NEVER use legacy handler scripts (handler-work-tracker-*) </CRITICAL_RULES>

Example Request

{
  "operation": "fetch-issue",
  "parameters": {
    "issue_number": "123",
    "working_directory": "/mnt/c/GitHub/myorg/myproject"
  }
}

<CLI_INVOCATION>

CLI Command

fractary work issue fetch <number> --json

CLI Response Format

Success:

{
  "status": "success",
  "data": {
    "id": "123",
    "number": 123,
    "title": "Fix login page crash on mobile",
    "body": "Users report app crashes when...",
    "state": "open",
    "labels": [{"name": "bug", "color": "d73a4a"}],
    "assignees": [{"login": "johndoe"}],
    "created_at": "2025-01-29T10:00:00Z",
    "updated_at": "2025-01-29T15:30:00Z",
    "closed_at": null,
    "url": "https://github.com/owner/repo/issues/123"
  }
}

Execution Pattern

# Execute CLI command
result=$(fractary work issue fetch "$ISSUE_NUMBER" --json 2>&1)
cli_status=$(echo "$result" | jq -r '.status')

if [ "$cli_status" = "success" ]; then
    # Extract issue data
    issue_id=$(echo "$result" | jq -r '.data.number')
    issue_title=$(echo "$result" | jq -r '.data.title')
    issue_state=$(echo "$result" | jq -r '.data.state')
    issue_url=$(echo "$result" | jq -r '.data.url')
fi

</CLI_INVOCATION>

<NORMALIZED_RESPONSE> The skill normalizes CLI response to the universal data model:

{
  "id": "123",
  "identifier": "#123",
  "title": "Fix login page crash on mobile",
  "description": "Users report app crashes when...",
  "state": "open",
  "labels": ["bug", "mobile", "priority-high"],
  "assignees": [{"id": "123", "username": "johndoe"}],
  "author": {"id": "456", "username": "janedoe"},
  "createdAt": "2025-01-29T10:00:00Z",
  "updatedAt": "2025-01-29T15:30:00Z",
  "closedAt": null,
  "url": "https://github.com/owner/repo/issues/123",
  "platform": "github",
  "comments": []
}

Required Fields

• id: Platform-specific identifier
• identifier: Human-readable identifier (#123)
• title: Issue title
• state: Normalized state (open, closed)
• url: Web URL to issue
• platform: Platform name (github, jira, linear) </NORMALIZED_RESPONSE>

Success Response:

{
  "status": "success",
  "message": "Issue #123 fetched: Fix login page crash on mobile",
  "details": {
    "operation": "fetch-issue",
    "issue": {
      "id": "123",
      "identifier": "#123",
      "title": "Fix login page crash on mobile",
      "description": "Users report app crashes when...",
      "state": "open",
      "labels": ["bug", "mobile"],
      "assignees": [{"username": "johndoe"}],
      "url": "https://github.com/owner/repo/issues/123",
      "platform": "github"
    }
  }
}

Failure Response (Issue Not Found):

{
  "status": "failure",
  "message": "Issue #999 not found",
  "details": {
    "operation": "fetch-issue",
    "issue_id": "999"
  },
  "errors": ["Issue #999 does not exist in repository"],
  "error_analysis": "The specified issue number does not exist or you may not have access",
  "suggested_fixes": [
    "Verify issue number is correct",
    "Check repository access"
  ]
}

<ERROR_HANDLING>

Error Scenarios

Issue Not Found

• CLI returns error code "NOT_FOUND"
• Return error JSON with message "Issue #X not found"
• Suggest verifying issue ID

Authentication Failed

• CLI returns error code "AUTH_FAILED"
• Return error with auth failure message
• Suggest checking GITHUB_TOKEN or running gh auth login

Network Error

• CLI returns error code "NETWORK_ERROR"
• Return error with network failure message
• Suggest checking internet connection

Invalid Issue ID

• issue_number parameter missing or empty
• Return error with validation message
• Show expected format </ERROR_HANDLING>

Start/End Message Format

Start Message

🎯 STARTING: Issue Fetcher
Issue ID: #123
───────────────────────────────────────

End Message (Success)

✅ COMPLETED: Issue Fetcher
Issue: #123 - "Fix login page crash on mobile"
State: open
Labels: bug, mobile, priority-high
Platform: github
───────────────────────────────────────
Next: Use classify operation to determine work type

Dependencies

• @fractary/cli >= 0.3.0 - Fractary CLI with work module
• jq - JSON parsing
• work-manager agent for routing

Migration Notes

Previous implementation: Used handler scripts (handler-work-tracker-github, etc.) Current implementation: Uses Fractary CLI directly (fractary work issue fetch)

The CLI handles:

• Platform detection from configuration
• Authentication via environment variables
• API calls to GitHub/Jira/Linear
• Response normalization

This skill is now a thin wrapper that:

1. Validates input
2. Invokes CLI
3. Maps response format
