Server-prepared memory context appended to the system prompt requires a remote entrypoint and tengu_misty_anchor, which falls back to false.
New machinery lets a cloud session fetch a block of text prepared by the session host and append it to the system prompt before the conversation starts. It is off here: it requires a remote entrypoint, an auth check, and the tengu_misty_anchor flag, whose in-source fallback is false. Nothing in a normal local run fetches anything or changes the prompt.
- Fetches
GET /memory_contextfrom the session host with session-JWT auth, ETag revalidation viaIf-None-Match, a 10 second timeout and a 256KiB cap on the returned content. - The payload must be
{version, content}; malformed responses are rejected. - Prompt assembly waits up to 2000ms for the fetch before assembling, then appends the content as an extra system-prompt block.
- Handles 204 (no context), 304 (unchanged) and 429/503 (not built yet) distinctly.
- Restricted to the
remote_cowork,remote_cowork_trigger,remote_apiandremote_triggerentrypoints. - Emits
cowork_memory_context_fetched,_none,_not_built,_gatedand_malformed. - None of this existed in 2.1.245.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
tengu_misty_anchor Not enough to sayNothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
