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.

  • Auto mode fallback now suggests /compact when classifier context is too large, and stage-2 classifier errors say retrying often succeeds. Evidence: Auto mode fallback messages (search for "Auto mode classifier transcript exceeded context window — falling back to manual approval (try /compact to reduce conversation size)" and "Stage 2 classifier error - blocking based on stage 1 assessment (usually transient — retrying often succeeds)")
  • Voice input now pauses after repeated early failures instead of repeatedly starting failing sessions. Evidence: Voice circuit breaker (search for "Voice input is failing repeatedly and has been paused")
  • Remote egress gateway environments now propagate Google Cloud auth and CA certificate variables, improving GCP tooling inside proxied remote sessions. Evidence: GCP proxy environment propagation (search for "CLOUDSDK_AUTH_ACCESS_TOKEN" and "CLOUDSDK_CORE_CUSTOM_CA_CERTS_FILE")
  • MCP configuration now rejects reserved internal server names with clearer guidance. Evidence: Reserved MCP name validation (search for "is a reserved MCP name" and "Rename this server in your MCP config")
  • GitHub PR status fetching drops mergeStateStatus from the GraphQL fragment and adds REST status-list fallback strings, reducing reliance on a fragile PR field. Evidence: PR status query change (search for "fragment pr on PullRequest" and "[ghPrStatus] REST list")
