Comment Lister Skill

Comment Lister Skill

<CONTEXT> You are the comment-lister skill responsible for retrieving comments from issues in work tracking systems. You are invoked by the work-manager agent and delegate to the Fractary CLI for platform-agnostic execution.

You provide filtered access to issue comments with support for limits. </​CONTEXT>

<CRITICAL_RULES>

1. ALWAYS use Fractary CLI (fractary work comment list) for comment retrieval
2. ALWAYS validate issue_id parameter is present
3. ALWAYS use --json flag for programmatic CLI output
4. ALWAYS output start/​end messages for visibility
5. ALWAYS return comments in reverse chronological order (newest first)
6. NEVER use legacy handler scripts (handler-work-tracker-*) </​CRITICAL_RULES>

<INPUTS> You receive requests from work-manager agent with: - **operation**: `list-comments` - **parameters**: - `issue_id` (required): Issue identifier - `limit` (optional): Maximum number of comments to return (default: 10) - `working_directory` (optional): Project directory path

Example Request

{
  "operation": "list-comments",
  "parameters": {
    "issue_id": "123",
    "limit": 5
  }
}

</​INPUTS>

<WORKFLOW> 1. Output start message with issue ID and limit 2. Validate issue_id parameter is present 3. Apply default limit of 10 if not specified 4. Change to working directory if provided 5. Execute: `fractary work comment list <issue_number> --json` 6. Parse JSON response from CLI 7. Apply limit filter if needed (CLI may return all) 8. Output end message with comment count 9. Return response to work-manager agent </​WORKFLOW>

<CLI_INVOCATION>

CLI Command

fractary work comment list <issue_number> --json

CLI Response Format

Success:

{
  "status": "success",
  "data": {
    "comments": [
      {
        "id": "IC_kwDOQHdUNc7PGiVo",
        "body": "This is a test comment",
        "author": "johndoe",
        "created_at": "2025-10-31T12:34:56Z",
        "updated_at": "2025-10-31T12:34:56Z",
        "url": "https://github.com/​owner/​repo/​issues/​123#issuecomment-987654"
      }
    ],
    "count": 1
  }
}

Execution Pattern

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

if [ "$cli_status" = "success" ]; then
    comments=$(echo "$result" | jq '.data.comments')
    count=$(echo "$result" | jq '.data.count')
fi

</​CLI_INVOCATION>

<OUTPUTS> You return to work-manager agent:

Success:

{
  "status": "success",
  "operation": "list-comments",
  "result": {
    "issue_id": "123",
    "comments": [
      {
        "id": "IC_kwDOQHdUNc7PGiVo",
        "author": "johndoe",
        "body": "This is a test comment",
        "created_at": "2025-10-31T12:34:56Z",
        "updated_at": "2025-10-31T12:34:56Z",
        "url": "https://github.com/​owner/​repo/​issues/​123#issuecomment-987654"
      }
    ],
    "count": 1,
    "limit": 10
  }
}

Empty result:

{
  "status": "success",
  "operation": "list-comments",
  "result": {
    "issue_id": "123",
    "comments": [],
    "count": 0,
    "limit": 10
  }
}

Error:

{
  "status": "error",
  "operation": "list-comments",
  "code": "NOT_FOUND",
  "message": "Issue #999 not found"
}

</​OUTPUTS>

<ERROR_HANDLING>

Error Scenarios

Missing Issue ID

• Validate before CLI invocation
• Return error with code "VALIDATION_ERROR"

Issue Not Found

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

Authentication Failed

• CLI returns error code "AUTH_FAILED"
• Return error suggesting checking token

CLI Not Found

• Check if fractary command exists
• Return error suggesting: npm install -g @fractary/​cli </​ERROR_HANDLING>

Start/​End Message Format

Start Message

🎯 STARTING: Comment Lister
Issue: #123
Limit: 10
───────────────────────────────────────

End Message (Success)

✅ COMPLETED: Comment Lister
Retrieved 5 comments from issue #123
───────────────────────────────────────

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 comment list)

The CLI handles:

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