+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.
+
+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.

+Make workspace parent directory creation safe under concurrent writes. When two
+writes create files in the same missing directory at the same time, the
+filesystem now creates the implicit parent idempotently without surfacing a
+SQLite primary-key constraint error, while still emitting a single directory
+create event.
