Create structured Linear issues (main + sub-issues) with project linking, title prefix, and labeling. Supports two workflows: Generic (code tasks) and PRD Pipeline (제품 요구사항 정의서). PRD Pipeline applies content-strategy, content-production, content-humanizer, copy-editing principles to produce high-quality issue descriptions targeting fullstack developers in Korean. Use when asked to create, register, or break down tasks into Linear issues. Not for querying or updating.

Review completed Linear sub-issues: cross-validate Done Criteria, code changes, and worker comments to approve, request changes, or ask for clarification. Use when asked to review, validate, or QA done Linear issues.

Execute code tasks from Linear sub-issues: resolve dependencies, implement changes, validate Done Criteria, and sync status. Use when asked to work on, implement, or start coding a Linear issue (e.g. PRI-42).

Analyze repository structure and generate or update standardized AGENTS.md files that serve as contributor guides for AI agents. Supports both single-repo and monorepo structures. Measures LOC to determine character limits and produces structured documents covering overview, folder structure, patterns, conventions, and working agreements. Update mode refreshes only the standard sections while preserving user-defined custom sections, and only modifies AGENTS.md files previously generated by this skill — externally-authored files are reported, never rewritten. Use when the user wants an AGENTS.md generated or refreshed — setting one up for a new repository, onboarding AI agents to an existing codebase, updating an existing AGENTS.md, or when the user mentions AGENTS.md. Not for CLAUDE.md, README, or other documentation files.
