Skill/webhook/cron builders concatenate a large static scaffold with a small volatile tail into one user-message string. Only the builder knows where the tail begins, so it registers the stable prefix here and the cache planner places a breakpoint at that boundary. Re-parsing marker strings at request time is deliberately avoided: markers can legitimately appear inside skill bodies, and any delimiter heuristic then shrinks the cached prefix or absorbs volatile bytes. Process-local by design: any miss falls back to the whole-message policy.

The tail must be non-whitespace so the split never yields an empty text block (Anthropic rejects it with HTTP 400). A hit refreshes the entry's LRU position so a scaffold fired every minute by cron is not evicted by a burst of one-off skill invocations.
