Releases

agents@0.10.1

Patch Changes

• #1278 8c7caab Thanks @threepointone! - Think now owns the inference loop with lifecycle hooks at every stage.

  Breaking: onChatMessage(), assembleContext(), and getMaxSteps() are removed. Use lifecycle hooks and the maxSteps property instead. If you need full custom inference, extend Agent directly.

  New lifecycle hooks: beforeTurn, beforeToolCall, afterToolCall, onStepFinish, onChunk — fire on every turn from all entry paths (WebSocket, chat(), saveMessages, auto-continuation).

  beforeTurn(ctx) receives the assembled system prompt, messages, tools, and model. Return a TurnConfig to override any part — model, system prompt, messages, tools, activeTools, toolChoice, maxSteps, providerOptions.

  maxSteps is now a property (default 10) instead of a method. Override per-turn via TurnConfig.maxSteps.

  MCP tools auto-merged — no need to manually merge this.mcp.getAITools() in getTools().

  Dynamic context blocks: Session.addContext() and Session.removeContext() allow adding/removing context blocks after session initialization (e.g., from extensions).

  Extension manifest expanded with context (namespaced context block declarations) and hooks fields.

@cloudflare/ai-chat@0.4.1

Patch Changes

• #1272 22da9b1 Thanks @threepointone! - Widen useAgentChat agent prop type to accept both typed and untyped useAgent connections. Previously, useAgent<MyAgent>() results could not be passed to useAgentChat due to incompatible call types. The agent prop now uses a structural type matching only the fields useAgentChat actually uses.

@cloudflare/think@0.2.1

Patch Changes

• #1275 37b2ce3 Thanks @threepointone! - Add built-in workspace to Think. Every Think instance now has this.workspace backed by the DO's SQLite storage, and workspace tools (read, write, edit, list, find, grep, delete) are automatically merged into every chat turn. Override workspace to add R2 spillover for large files. @cloudflare/shell is now a required peer dependency.
