To invoke skills before replying, call the Skill tool at the start of every session to identify applicable skills and apply them before generating any response, including clarifying questions.

Skill priority is a framework that processes skills in a specific order—process skills first, then implementation skills—to guide task execution and reduce misfires during conversational AI interactions.

Yes, the skill invocation rule defines cross-platform access and mappings for Claude Code, Copilot CLI, and Gemini CLI, ensuring consistent skill activation and predictable behavior across all supported environments.

Invoking skills at the start of every conversation is required to establish how to find and use skills, ensuring actions are guided by user instructions, platform-specific access, and Resistance Engine rules before any steps are taken.

The best way to enforce pre-response skill activation is to implement access guidelines outlined in the SKILL.md, requiring the Skill tool to be invoked at session start to maintain predictable behavior across sessions.

Skipping the Skill tool invocation violates the pre-response rule, bypassing the identification of applicable skills and potentially causing misfires by not prioritizing user instructions and platform-specific skill access before replying.
