Comment Creator Skill

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

You support both FABER workflow comments (with metadata tracking) and standalone comments. </CONTEXT>

<CRITICAL_RULES>

1. ALWAYS use Fractary CLI (fractary work comment create) for comment posting
2. ALWAYS validate required parameters (issue_number, body/message)
3. ALWAYS use --json flag for programmatic CLI output
4. ALWAYS output start/end messages for visibility
5. CONDITIONALLY include FABER metadata footer only when faber_context is provided
6. NEVER use legacy handler scripts (handler-work-tracker-*) </CRITICAL_RULES>

<INPUTS> You receive requests from work-manager agent with: - **operation**: `create-comment` - **parameters**: - `issue_number` (required): Issue identifier - `body` or `message` (required): Comment content (markdown supported) - `faber_context` (optional): Phase context for FABER workflows - `working_directory` (optional): Project directory path

Example Request (Standalone)

{
  "operation": "create-comment",
  "parameters": {
    "issue_number": "123",
    "body": "This looks good to merge!"
  }
}

Example Request (FABER Workflow)

{
  "operation": "create-comment",
  "parameters": {
    "issue_number": "123",
    "body": "🎯 **Frame Phase Started**\n\nAnalyzing requirements...",
    "faber_context": "frame"
  }
}

</INPUTS> <WORKFLOW> 1. Output start message with issue number 2. Validate required parameters (issue_number, body) 3. Change to working directory if provided 4. Build comment body (optionally append FABER metadata footer) 5. Execute: `fractary work comment create <issue_number> --body "..." --json` 6. Parse JSON response from CLI 7. Output end message with comment details 8. Return response to work-manager agent </WORKFLOW>

<CLI_INVOCATION>

CLI Command

fractary work comment create <issue_number> --body "Comment content" --json

CLI Response Format

Success:

{
  "status": "success",
  "data": {
    "id": "12345678",

  }
}

Execution Pattern

# Build and execute CLI command
result=$(fractary work comment create "$ISSUE_NUMBER" --body "$COMMENT_BODY" --json 2>&1)
cli_status=$(echo "$result" | jq -r '.status')

if [ "$cli_status" = "success" ]; then
    comment_id=$(echo "$result" | jq -r '.data.id')
    comment_url=$(echo "$result" | jq -r '.data.url')
fi

</CLI_INVOCATION>

<OUTPUTS> You return to work-manager agent:

Success:

{
  "status": "success",
  "operation": "create-comment",
  "result": {
    "id": "12345678",
    "issue_number": "123",

    "url": "https://github.com/owner/repo/issues/123#issuecomment-12345678",
    "platform": "github"
  }
}

Error:

{
  "status": "error",
  "operation": "create-comment",

Dependencies

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

Migration Notes
