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.

Session wiring moved into one controller with a cached tool list

Under the hood
Useful2 Signal2
Session Lifecycle

Session start, resume and adoption now live in one controller, and the tool list is recomputed less often.

What

Session start, resume, adoption of agents, shells and workflows, orphan resume and Artifact live-watch rearming now live in a single controller class, and the tool list is recomputed only when its inputs change rather than on every pass.

Details
  • The cache is keyed on the identity of the permission context, MCP tools and clients, skill tools, agent definitions, repl bridge flags and slack tag.
  • App state gained artifactRoomJoinConsentSlugs, which records per-Artifact consent to join its comment room.
Evidence

SessionController: used before its screen bound a host

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