 - Browser/Chrome MCP: remove the legacy Chrome extension relay path, bundled extension assets, `driver: "extension"`, and `browser.relayBindHost`. Run `openclaw doctor --fix` to migrate host-local browser config to `existing-session` / `user`; Docker, headless, sandbox, and remote browser flows still use raw CDP. (#47893) Thanks @vincentkoc.
 - Plugins/runtime: remove the public `openclaw/extension-api` surface with no compatibility shim. Bundled plugins must use injected runtime for host-side operations (for example `api.runtime.agent.runEmbeddedPiAgent`) and any remaining direct imports must come from narrow `openclaw/plugin-sdk/*` subpaths instead of the monolithic SDK root.
+- Tools/image generation: standardize the stock image create/edit path on the core `image_generate` tool. The old `nano-banana-pro` docs/examples are gone; if you previously copied that sample-skill config, switch to `agents.defaults.imageGenerationModel` for built-in image generation or install a separate third-party skill explicitly.

+- Only available when `agents.defaults.imageGenerationModel` is configured.
+- Use `action: "list"` to inspect registered providers, default models, supported model ids, sizes, resolutions, and edit support.
+- Returns local `MEDIA:<path>` lines so channels can deliver the generated files directly.
+- Uses the image-generation model directly (independent of the main chat model).
+- Google-backed flows support reference-image edits plus explicit `1K|2K|4K` resolution hints.
+- When editing and `resolution` is omitted, OpenClaw infers a draft/final resolution from the input image size.
+- This is the built-in replacement for the old sample `nano-banana-pro` skill workflow. Use `agents.defaults.imageGenerationModel`, not `skills.entries`, for stock image generation.
