Patch Changes

• #1613 `124a47a` Thanks @threepointone! - Introduce the first Think framework layer for convention-driven agent apps.

This release adds a manifest-driven Vite plugin that discovers agents from the agents/ directory, generates a Worker entrypoint and virtual framework modules, derives stable Durable Object class names, and merges framework-owned Worker config defaults with user Wrangler config. It also keeps the Think Vite plugin usable directly in normal Vite plugin arrays.

The framework now supports optional app server entries, manifest-scoped friendly agent and sub-agent routing, deterministic route surfaces, colocated skill detection, Worker Loader requirement diagnostics, and explicit diagnostics for unsupported nested sub-agent conventions. Think currently supports top-level agents and one sub-agent layer; deeper nesting is rejected with guidance so that the routing and lifecycle model can be designed deliberately.

This framework layer is experimental: both the Vite plugin (once, on build start) and the think CLI (on startup) emit a notice that the API may change or be removed in any release. The core Think agent runtime is unchanged.

The Think CLI now includes think init, think inspect, and think types. think init scaffolds a minimal Workers/Vite Think app, safely handles prompted or named target directories, refuses unsafe migrations, and installs npm dependencies by default. think inspect exposes manifest/config diagnostics in text or JSON, while think types generates Think-owned declarations and can optionally compose with Wrangler type generation.

This release also adds host-framework coverage for React Router and TanStack Start, updates examples to use the convention-first framework shape, and hardens Agents/worker-bundler virtual modules for bundled skill compatibility.

• #1613 `124a47a` Thanks @threepointone! - Compile skill scripts ahead of time and remove the in-Worker bundler (drops ~14MB of esbuild-wasm from Worker bundles).

Skill scripts are now always compiled to self-contained JavaScript before they run, and the runtime no longer ships an in-Worker bundler (@cloudflare/worker-bundler is no longer a dependency of agents):

• The Agents Vite plugin compiles bundled skill scripts (scripts/*.ts/.tsx/.js/.mjs) with esbuild at build time — resolving sibling imports and stripping TypeScript — and marks them precompiled.
• Skills served from R2 or other dynamic sources must be compiled before upload. A new compileSkillScript helper is exported from agents/skills/compile for use in your publish/upload tooling.
• At runtime, a skill script that still needs compiling (raw TypeScript or a multi-file skill that wasn't bundled) throws a clear "must be compiled to a self-contained JavaScript module" error instead of silently bundling in-Worker.

Breaking: if you ship raw TypeScript or multi-file skill scripts to R2 (or another dynamic source) and relied on the in-Worker bundler to compile them at runtime, bundle them ahead of time (e.g. with compileSkillScript) before upload. Bundled skills handled by the Vite plugin require no changes. The previously-added stubWorkerBundler option has been removed (there is nothing left to stub).
