Explicit invocation only. Apply only when the user's latest request invokes `/precise-terms`, writes `$precise-terms`, or directly asks to use the `precise-terms` skill. Transform verbose descriptions into concise, high-signal prompts or canonical technical terms, especially for coding, UI, motion design, UX, and architecture. Mere discussion of the skill is not an invocation. Never infer activation from an ordinary request to edit, clarify, shorten, optimize, make precise, find better terms, or refine a prompt.
