COG Create User Story Skill

When to Invoke

User wants to create a new user story, feature request, or issue
User says "create story", "new story", "add issue", "write user story", "create ticket"
User describes a feature or requirement that should be tracked

Agent Mode Awareness

Check agent_mode in 00-inbox/MY-PROFILE.md frontmatter:

If agent_mode: team — use parallel agents to check for duplicates across all active trackers simultaneously, then create the story
If agent_mode: solo — check duplicates and create the story sequentially in the main conversation

Command: `/create-user-story`

Pre-Flight Check

Read 00-inbox/MY-INTEGRATIONS.md to determine which project trackers are active:
- Linear — use Linear MCP tools
- GitHub — use gh CLI
- Jira — use jira CLI or Jira API via WebFetch
- If NO tracker is active, save the story as a markdown file in 04-projects/[project]/stories/ and inform the user
Read 00-inbox/MY-PROFILE.md to get:
- Active projects (to determine which project/repo/board to target)
- User's name (for story author attribution)
Ask the user (if not already provided):
- What is the feature or requirement? (free-form description)
- Which project does this belong to? (if multiple active projects)
- Priority level? (optional — default to medium)

Execution Strategy

Phase 1: Understand the Request

Parse the user's input to extract:

Feature description — what the user wants built
