chore: release v4.5.0-rc.4

[github-actions]

Summary

1 new feature, 5 improvements.

Highlights

• Mollifier mutateSnapshot now enforces a tag cap: an append_tags patch carrying maxTags returns "limit_exceeded" (writing nothing) when the deduped tag count would exceed the limit, so a buffered run can't accumulate more tags via the tags API than the trigger validator allows at creation. (#3756)

Improvements

• Mollifier buffer extensions: idempotency dedup, an atomic mutateSnapshot API, metadata CAS, claim primitives, and a MollifierSnapshot type. The buffer's Redis client now reconnects with jittered backoff so a fleet of clients doesn't stampede Redis in lockstep after a blip. (#3752)
• Add onTerminalFailure callback to MollifierDrainerOptions so the customer's run lands a SYSTEM_FAILURE PG row even when the drainer exhausts maxAttempts on a retryable PG error. Previously, retryable-error exhaustion called buffer.fail() directly, which atomically marks FAILED + DELs the entry hash with no PG write — silent data loss when PG was unreachable across the full retry budget. The callback fires before buffer.fail() on any terminal path (cause: "non-retryable" or "max-attempts-exhausted"); throwing a retryable error from the callback causes the drainer to requeue rather than fail. (#3754)
• Bump @s2-dev/streamstore to 0.22.10 to fix a TASK_RUN_UNCAUGHT_EXCEPTION ("Invalid state: Unable to enqueue") when a chat.agent turn is aborted mid-stream. (#3792)
• Coerce numeric concurrencyKey values to string at the API boundary across tasks.trigger, tasks.batchTrigger, and the Phase-2 streaming batch endpoint. (#3789)
• Add a tools option to chat.agent. Declaring your tools here threads them into the SDK's internal convertToModelMessages, so each tool's toModelOutput is re-applied when prior-turn history is re-converted. (#3790)

Minor Changes

• Mollifier buffer extensions: idempotency dedup, an atomic mutateSnapshot API, metadata CAS, claim primitives, and a MollifierSnapshot type. The buffer's Redis client now reconnects with jittered backoff so a fleet of clients doesn't stampede Redis in lockstep after a blip. (#3752)

The callback fires before buffer.fail() on any terminal path (cause: "non-retryable" or "max-attempts-exhausted"); throwing a retryable error from the callback causes the drainer to requeue rather than fail. (#3754)

Patch Changes

• Pipeline the per-entry HGETALL fetches in MollifierBuffer.listEntriesForEnv. The previous serial implementation issued one Redis round-trip per runId returned by LRANGE, which dominated stale-sweep wall-time at any meaningful backlog (at the sweep's default maxCount=1000, this is ~1000 RTTs per env per pass). Behaviour is unchanged — entries are still skipped when the entry hash has been torn down by a concurrent drainer ack/fail between the LRANGE and the HGETALL. (#3752)
• Mollifier mutateSnapshot now enforces a tag cap: an append_tags patch carrying maxTags returns "limit_exceeded" (writing nothing) when the deduped tag count would exceed the limit, so a buffered run can't accumulate more tags via the tags API than the trigger validator allows at creation. (#3756)

  chat.agent({
    tools: { readFile, search },
    run: async ({ messages, tools, signal }) =>
      streamText({ model, messages, tools, abortSignal: signal }),
  });

  Also exports InferChatUIMessageFromTools<typeof tools> to derive the chat UIMessage type (typed tool parts) directly from a tool set.
