continue.md exists for exactly this — see auto-prompts.ts, guided-flow.ts, phase-anchor.ts, state.ts. This skill is the deliberate authoring ritual.

Invocation points:

User says "pause", "hand off", "I'll come back later", "this is a good stopping point"
Context usage nearing budget — better to hand off cleanly than truncate mid-thought
Before a risky operation (dependency upgrade, major refactor) where you want a known-good checkpoint
End of a long session, multi-day work

<core_principle> WRITE FOR A STRANGER. The next reader is not you. They do not have this conversation. They have STATE.md, continue.md, the last summary, and the code. That has to be enough.
