DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Plan files can be watched through the newer storage backend

Useful2 Signal3
Plan Mode

Plan files can stay in sync via change notifications on the newer storage backend.

Only active when the newer storage backend is selected and passed in.

What

Plan files (the saved output of plan mode) can be kept in sync by subscribing to change notifications from Claude Code's newer storage backend instead of re-reading on demand. It only runs when that backend is both selected by an internal check and passed in, so on the older storage path nothing changes.

Details
  • Per-plan subscription with generation counters, refresh on change events, one automatic resubscribe if the watch ends, release of stale watches, and a cap on how long a read will wait.
  • If subscribing fails it logs and serves the last value read plus any writes made in this process, so a plan is never unavailable.
  • The check that selects the newer backend is compiled down to an unnamed predicate, so which flag or setting decides it is not visible in the build.
Evidence

plans: watching

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
