Ito Trainingaffaan-m/eccInspect the availability of ML training on a completed Itô compute booking and, when the canonical backend becomes available, hand off an explicitly confirmed training manifest. Use after ito-compute has booked GPU nodes and the user wants pre-training, fine-tuning, or RL on that metal.

Use when p95 latency or data freshness matters — realtime dashboards, market data, streaming agents, queues, or caches.01Lead Intelligenceaffaan-m/ecc日本語翻訳：このファイルは lead-intelligence 用の日本語翻訳が必要です01Liquid Glass Designaffaan-m/ecc日本語翻訳：このファイルは liquid-glass-design 用の日本語翻訳が必要です01Literature Reviewaffaan-m/ecc学術、生物医学、技術、科学的なトピックに対するシステマティックな文献レビューワークフロー。検索計画、ソースのスクリーニング、統合、引用確認、証拠ログを含む。01Living Docs Governanceaffaan-m/eccKeep a long-lived project's documentation from rotting by assigning existing project docs clear constitution, map, status, and history roles, then wiring the active agent harness to those canonical sources. Use in the maintain phase when docs drift from code, agents lose context between sessions, or intentional removals keep being recreated. Prefer adopting the repository's current docs structure over creating new root files. 中文触发：文档治理、活文档、项目状态追踪、防文档漂移、项目地图、健康仪表盘、删除区、长期项目治理01LLM Trading Agent Securityaffaan-m/ecc日本語翻訳：このファイルは llm-trading-agent-security 用の日本語翻訳が必要です01Logistics Exception Managementaffaan-m/ecc日本語翻訳：このファイルは logistics-exception-management 用の日本語翻訳が必要です01Loop Design Checkaffaan-m/eccDesign a goal-oriented agent loop, and review it for the ways loops go wrong — spinning and burning tokens, Goodhart-gaming the verifier, or running a wrong answer to completion. Two actions: (1) WRITE a loop — gate whether to build it, define a machine-decidable goal, pick the loop type, pick a skeleton; (2) REVIEW a loop — run it past five failure modes plus decidability, boundaries, fallback, judge independence, and keep-judgment-with-the-human red lines. Use when designing an autonomous agent loop, or when you already have one and worry it will spin, cheat, or run a wrong answer to the end. Complements the mechanism-layer loop skills (autonomous-loops, continuous-agent-loop) by covering the judgment layer they don't. 中文触发：写 loop、设计 loop、做一个 loop、检查 loop 对不对、loop 体检、loop 会不会跑飞、可判定目标、五个崩法、plan build judge。English triggers: design an agent loop, write a loop, check a loop, loop review, prevent a runaway loop, goal-oriented loop, decidable goal, plan/build/judge.01Mailtrap Email Integrationaffaan-m/eccGuides agents through integrating transactional email sending via Mailtrap's Email API, including sandbox testing, domain verification, and API authentication.
