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.

Storage-backend addressing added across transcripts, sidecars and caches

Storage Backend

Transcripts, caches, plugin state and more gained storage-backend addresses that no ordinary install uses.

Backend-addressed paths exist across many on-disk files but only run with a v5 storage backend supplied.

What

A wide set of on-disk state gained backend-addressed equivalents with filesystem fallbacks: subagent transcripts and their .meta.json sidecars, session alias files, the MCP discovery cache, marketplace manifests and installed-plugin state, forked-skill scoping records, and the active-time ledger. These paths are only taken when a v5 storage backend is supplied, so on an ordinary install nothing changes.

Details
  • Listings are paginated with explicit page budgets, and log when a listing was cut short or failed.
  • A failed listing yields an empty result rather than a partial one.
