Introduce a WebUI extension manifest and rewrite the asset bundler/server to support caller-supplied entry sets, extension-injected entries, and negotiated gzip. Key changes: add get_webui_extension_manifest() to helpers/extension, refactor Stop logic into stop_context() and reuse it from the connector `/stop` command, and add a new `/rename` slash command for chat naming. ui_bundler now accepts entry_urls, includes enabled extension entry files, raises the embedded text file size limit to 512 KiB, computes per-entry-set cache keys, and returns a bundle version based on the bundle signature. ui_server applies Starlette GZip middleware, adds routes (/, /index.html, /ui/index, /safe), serves splash/safe documents, injects the serialized webui_extension_manifest into the rendered index, and streamlines the /ui/asset-bundle endpoint with ETag and gzip handling. Also add multiple WebUI assets and fonts, new/updated plugin command YAML and Python command handlers, and corresponding tests covering bundling, commands, chat naming, and WebUI behaviors. Documentation (.dox.md) updated to reflect the new runtime contracts and guidance.
Delete the Core WebUI gateway menu and its client-side control store so Host access stays owned by A0 Launcher. Keep /computer-use informational in WebUI and direct users to Launcher or A0 CLI for host changes.
Continue active goals through response attempts until they are completed or genuinely blocked, while directing agents to make safe in-scope choices autonomously.
Parse known slash commands in prefix or trailing position for WebUI and backend-originated messages.
Make /computer-use on and off act on the current Launcher Host access lease while preserving A0 CLI guidance in ordinary WebUI sessions.
Update connector prompts and regressions so permission recovery consistently accounts for both Launcher and CLI entry points.
List bundled slash commands in their own section and create same-name project or global overrides when users edit them.
Remove the Commands sidebar shortcut and redundant scope banner, then simplify command cards by dropping badges and argument hints while tightening description typography. Add regression coverage for built-in listing and override precedence.
Introduce the _commands plugin with command storage, picker UI, bundled canonical command pack, and legacy migration into the built-in namespace.
Polish the Web UI picker behavior, hide WebUI-only-inappropriate commands from the popover, make /models always open model configuration, and add regression coverage for command CRUD, plugin discovery, migration, canonical names, hidden commands, and picker flows.
