This skill should be used when estimating development time for Jira tickets. It provides both manual and AI-assisted estimates with T-shirt sizes, story points, and phase-by-phase time breakdowns based on task type classification, complexity scoring, and project architecture (monolithic/serverless/frontend/fullstack/mobile/test_automation).

This skill should be used when users need to fetch Jira ticket content using either a specific ticket ID (like RD-3891) or search for tickets by title/description. It defaults to searching within the current sprint but can extend to all tickets when needed. The skill uses the Jira CLI to retrieve ticket details, status, assignee, and descriptions.
