What problem does it solve? AI agents often skip available skills and improvise answers, leading to inconsistent workflows and missed best practices. This Skill establishes a mandatory discipline: check for and invoke applicable skills before any response, including clarifying questions or codebase exploration. ## Core Features & Use Cases - Mandatory Skill-First Rule: Requires invoking any potentially relevant skill before responding, with a red-lines table that counters common rationalizations for skipping skills. - Skill Priority Routing: Defines precedence rules where process skills (brainstorming, systematic debugging) run before implementation skills, plus routing to Chinese-localized skills for Chinese-language projects. - Cross-Platform Tool Mappings: Ships reference files mapping Claude Code tool names to equivalents in Codex, Gemini CLI, Copilot CLI, Pi, Antigravity, Hermes Agent, and Qoder. - Use Case: An agent asked to "fix this bug" first invokes the systematic-debugging skill rather than jumping straight into editing code, ensuring a disciplined root-cause workflow. ## Quick Start Start every conversation by checking which skills apply to the user's request and invoke the matching skill before responding.
