Without this flag the existing two-tool surface and +metadata-only discovery stay unchanged. This option explicitly permits conversation +text to reach the MCP client; local-user access to the selected home is not +per-project/thread authorization.

Each call searches at most one page of 50 stored items. A matched +input identifies a turn, and the tool returns one page of that turn's explicit +`final_answer` agent texts. It omits user bodies, reasoning, commands, citations +and tool outputs. The entire call has a shared 20-second budget across up to +three sequential helpers, plus owned cleanup. Each helper retains the existing +12-second RPC deadline and 1 MiB output cap. Text is limited to 16 KiB per result +page, with valid UTF-8 and an explicit per-item `truncated` flag. `nextCursor` +continues items, not omitted bytes of a truncated item. + +Results distinguish these observations: + +- `observed`: the input was matched. `replies` can still be empty. The association + is always `same_turn_not_exclusive`: the result contains final texts from the + same turn, not a certified answer solely to that input. Text can precede a later + input in a shared turn. `turnStatus` is observed from the newest 50 turn summaries, + or `unverified` when outside that window; a completed turn does not complete a goal. +- `not_observed`: no matching input in this search page. This does not mean + non-delivery, deletion or no response. `reachedHistoryEnd` describes this search + position, not delivery or processing. Continue a non-null `nextCursor` to search older items. +- `ambiguous`: multiple matching inputs occurred in the search page. No text is returned. +- `available: false`: disabled access, invalid input/cursor, malformed history, + an unavailable/unsupported native method, cancellation or another read failure. + Native diagnostics are not exposed and failures are not empty successes. + +Pass `nextCursor` back as `cursor` to continue a search or matched-turn page. +After a match, `refreshCursor` rescans that turn from its beginning, allowing +an item that was partial earlier to appear when finalized later. Revisit all +pages when refreshing long turns. Keep/update item IDs in the caller to avoid +duplicates; the host adds no persistent inbox or background polling. A null +`nextCursor` ends only the current history snapshot, not future output. + +Cursors are bounded, caller-owned position data bound to both request IDs. They +are not signed permissions. A matched-turn continuation re-reads the user item to +check its ID, turn and client correlation before projecting turn text. Stale, +malformed or cross-scope positions fail closed rather than restarting all history. +The native methods are `thread/items/list`, `thread/items/read` and +`thread/turns/list`, with no resume, steer, turn start or queue mutation. + +This opt-in contract was observed with Codex CLI 0.166.0. Older builds or legacy +stores can be unavailable; there is no unbounded full-history fallback. These +reads do not prove recipient liveness, goal completion or Claude Desktop registration, +and do not add automatic reply delivery or a reverse Claude transport. ## Discover and send diff --git a/docs-site/src/content/docs/tr/reference/cli/messaging.md b/docs-site/src/content/docs/tr/reference/cli/messaging.md index e88dea990d1..126675b548b 100644 --- a/docs-site/src/content/docs/tr/reference/cli/messaging.md +++ b/docs-site/src/content/docs/tr/reference/cli/messaging.md @@ -15,6 +15,11 @@ stdio app-server başlatır.

Helper shutdown is allowed to outlive the deadline, so a valid snapshot whose frames all arrived in time could be discarded and reported as wait_exhausted or as a stale earlier snapshot. Track timeliness per RPC inside queueMcpReadReply and report it to callers through onObservedSuccess. A snapshot now succeeds only when every read behind it arrived before the deadline: late cleanup keeps a timely snapshot, a snapshot whose reads completed late is expired even when its data looks valid, and a stale timely snapshot cannot authorize a later late one. Parent cancellation still takes precedence. Cover both cases deterministically with synthetic helper fixtures, for a first and a subsequent snapshot, and document the arrival rule.
