This PR was opened by the Changesets release GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to main, this PR will be updated.

Releases

eve@0.31.0

Minor Changes

• 40b09e6: Replace continuation-token session APIs with fixed, ID-addressed handles and consistent channel-local operations. This is a breaking migration across the following public surfaces:

  • TypeScript clients now use client.sessions.create(input) to start a session and client.sessions.attach(sessionId) to obtain a fixed handle; client.session(...) and continuation-token client state are removed.
  • Client, eval, frontend, fixed-session, and Slack message delivery now use positional send(message, options). HITL replies use the separate respond(inputResponses, options) method, and message and inputResponses are mutually exclusive.
  • Custom channels use from(address) for channel-local operations, top-level resolveSession(address) to resolve the current owner, attachSession(sessionId) for an immutable session handle, and to(channel, target) for cross-channel delivery.
  • Slack message and interaction hooks expose ctx.send, ctx.respond, ctx.cancel, ctx.compact, ctx.clear, ctx.reset, and ctx.resolveSession. For generic events, the target is passed in each operation's options; ctx.receive and resolveActiveSession are removed.
  • Schedule handlers replace receive(channel, { message, target, auth }) with to(channel, target).send(message, { auth }).
  • Channel event session identity moves to ctx.session.id, while session.failed includes sessionId in its event data.
  • The eve HTTP API keeps POST /eve/v1/session for creation and POST /eve/v1/session/:sessionId for follow-ups. Clear, compact, and reset move from continuation-token body routes to POST /eve/v1/session/:sessionId/{clear,compact,reset}; cancel and streaming remain ID-addressed.
  • Session message and control bodies no longer accept or return continuation tokens. Accepted asynchronous work returns HTTP 202; no-active operation results omit sessionId, and inactive follow-ups return HTTP 409 with code: "session_not_active", available as ClientError.code.
  • Canonical eve onMessage hooks can no longer drop an otherwise authorized delivery by returning null.

Patch Changes

• 2054b9f: Agent-messaging <agents> listings are now announced as framework-injected user-role notes instead of assistant messages appended to history. This fixes parent resume failures on models that reject assistant-final requests (e.g. This model does not support assistant message prefill from Claude via AI Gateway) after a persistent child parks, keeps the announcement append-only so provider prompt caches stay warm, and the agent-messaging system prompt now declares the [Agents] note as framework-injected.
• 84c3dfc: Flush local development streaming response headers immediately so pending Workflow streams can be cancelled without accumulating listeners.
• b7a2a14: Dev runtime snapshots now mount workspace dependency packages in place
  instead of copying them. Only roots that host runtime-hydrated authored
  source — the app root, extension mount roots, and tsconfig path-alias
  targets — are still copied, matching how installed dependencies already
  resolved. In monorepos this removes the largest per-generation copy: a
  workspace-linked framework package (hundreds of files and tens of
  megabytes per rebuild) no longer lands under
  .eve/dev-runtime/snapshots/.

Build Timing: e2e/fixtures/agent-tools-sandbox

This is an informational timing measurement inside eve build, from preflight through publication. Output-size measurement and profile writing are excluded.

Build mode: deployable Vercel build with sandbox template prewarm included.

• Build pipeline: 1.49 s -> 1.99 s (+502.2 ms) vs main (84c3dfc).
• Timing is informational: shared GitHub runners are too variable for a hard timing budget.
