This skill provides screenplay page count and runtime estimation formulas. Covers the page-to-screen rule (1 page = 1 minute), genre adjustments, target lengths for features vs shorts, and element-based calculations. Use when: estimating screenplay length, calculating runtime, tracking page count, or validating target length for submission requirements.
Review and audit code quality, architecture, and implementation. Verify code meets design specs, find bugs, identify improvements, and create change/bug/improve backlogs. Use when reviewing completed code, auditing implementations, or ensuring quality.
Explain technical projects, codebases, tools, or documentation to a non-engineer. Use when the user says "orient me", "explain this repo", "what does this do", "get me up to speed", "break this down for me", or shares a GitHub URL asking for explanation. Also use when a non-technical person needs to understand something technical quickly.
Execute an implementation plan task-by-task with TDD and continuous quality checks. Use when asked to "implement the plan", "execute the tasks", "start building from the plan", or after /arc:detail has created an implementation plan ready for execution.
Diagnose and fix convergent ideation. Use when brainstorming produces the same ideas every time, when all ideas cluster around one approach, or when you need to escape domain defaults.
Use when initiating new features, complex code changes, or technical research tasks that require structured planning and documentation before implementation.
Manages session state and context handoffs for multi-session projects using the Session Handoff Protocol. Creates and maintains SESSION.md to track phase progress, git checkpoints, and next actions across context clears. Integrates with project-planning skill to convert IMPLEMENTATION_PHASES.md into trackable session state. Use when starting new projects after planning, resuming work after context clear, or managing complex multi-phase implementations. Keywords: session management, SESSION.md, session handoff protocol, context handoff, multi-session projects, phase tracking, git checkpoints, session state tracking, resume work, context clear, phase progress tracking, implementation phases, verification stage, debugging stage, next action tracking, work continuity, session recovery, context management, phased implementation tracking
Display the execution status of a plan by parsing frontmatter metadata. Shows progress at-a-glance without requiring manual inspection of each file.
Escalation path when stuck on pattern development. Use when encountering TypeScript errors, framework confusion, unexpected behavior, or blocked progress. Five-step recovery: check docs, study examples, strategic investigation (plan mode + subagents), reset and retry, ask user.
GitHub PRの未解決Review threadsを一括Resolveします。GraphQL APIで未解決のReview threads（コード特定行へのコメント）を取得し、resolveReviewThread mutationで全て自動的にResolveします。Issue comments（会話タブ）は元々Resolve機能がないため対象外です。各スレッドのResolve結果を表示します。
Quick build for small-to-medium scope work without formal planning. Still uses TDD and verification. Use when asked to "build this", "add a quick feature", "make this change", or for straightforward implementation tasks that don't need extensive design work.
Optimize multi-agent systems with coordinated profiling, workload distribution, and cost-aware orchestration. Use when improving agent performance, throughput, or reliability.
Transform PBIs into ready status for AI execution. Use when refining backlog items, splitting stories, or ensuring Definition of Ready.
Master skill for comprehensive security analysis. Identifies technology stack and delegates to specialized security sub-skills for deep vulnerability assessment.
Triages tachograph infringements, identifies common patterns, and outputs “what to check next” prompts and weekly review notes. USE WHEN doing weekly tacho/WTD reviews.
Verifies Trellis issues against original requirements for completeness, correctness, and appropriate scope. Use when asked to "verify issue", "validate trellis issue", "check issue completeness", or "review created issue".
Track multi-session work with dependencies using yatl (Yet Another Task List). Use when work spans multiple sessions, has dependencies, or requires persistent context across compaction cycles. For simple single-session linear tasks, TodoWrite remains appropriate.
Swiss Public Transport real-time information. Use when querying train, bus, tram, or boat schedules in Switzerland. Supports station search, departure boards, journey planning from A to B, and connection details. Use for queries like "When does the next train leave from Zürich?" or "How do I get from Bern to Geneva?" or "Show departures at Basel SBB".
Persistent TODO scratch pad for tracking tasks across sessions. Use when user says "add to TODO", "what's on the TODO", "mark X done", "show TODO list", "remove from TODO", or asks about pending tasks. Also triggers on heartbeat to remind about stale items.
This snippet should be used when creating technical execution plans in HTML format with mandatory quality review before display.
