WHY you should care
v2.1.218 ships a behavioral shift: context: fork skills no longer block the invoking turn. Your turn returns immediately, result arrives later. If you had skills that depended on the fork completing before the next step, they'll silently break.
What changed
- Forked skills background by default — add
background: false to frontmatter to restore old blocking behavior
/code-review is now a forked subagent — can't be stacked mid-chain anymore (it ends skill expansion)- Subagent edits escape checkpoints —
/rewind won't undo edits from background skills or /code-review --fix
/deep-research no longer self-invokes — only runs when you explicitly call it- New
disableMobileSimulatorTools managed setting — blocks Claude's programmatic access to iOS Simulator pane
- Boolean fields now accept yes/no/on/off/1/0 in skill frontmatter
