Work Handoff

Preserve continuity in one durable file rather than in conversation history. Automatic context compaction is not a handoff: it summarizes what was said, not what was verified, and it does not survive a new session.

Xcode Availability

Xcode can use the Write and Resume procedure when asked directly, but does not run this skill's Codex or Claude prompt wrappers and hooks. Invoke the skill in an Xcode conversation and state write or resume plus the optional task slug in the request; capture remains manual before an interruption.

Read $ARGUMENTS when the harness provides it.
