Commands Plugin DOX

Purpose

• Own the built-in slash command manager and chat composer slash picker.
• Keep file-backed /command discovery consistent across project, global, and plugin-provided scopes.

Ownership

• plugin.yaml owns the built-in _commands plugin metadata.
• helpers/commands.py owns command name sanitization, argument parsing, scope resolution, file persistence, plugin command discovery, and command invocation resolution.
• api/commands.py owns the Commands API actions used by the WebUI.
• webui/ owns the manager/editor modal stores, HTML surfaces, and thumbnail asset.
• commands/ owns bundled read-only slash command definitions shipped by _commands, including /stop agent-run control.
• extensions/ owns the chat composer slash picker and incoming-message command resolution.
• extensions/python/startup_migration/ owns one-time migration from the legacy community commands plugin namespace.
• skills/commands-create-slash-command/ owns the agent-facing authoring workflow for reusable slash commands.
• tests/ owns regression coverage for parsing, CRUD, scope precedence, plugin-distributed commands, legacy migration, and skill discovery.

Local Contracts

• The plugin identity is _commands; user-created command files live under usr/plugins/_commands/commands/ or usr/projects/<project>/.a0proj/plugins/_commands/commands/.
• Each command is one .command.yaml config plus one same-directory .txt text template or .py script hook.
• Project commands override global commands, global commands override bundled _commands/commands/ defaults, and bundled defaults override other plugin-distributed commands with the same name.
• Bundled _commands/commands/ definitions and commands contributed by other plugins are read-only from this manager.
• The manager lists bundled commands separately; editing one copies it unchanged into the selected project or global scope under the same name, then edits that higher-precedence override.
• Bundled command files use canonical command names only; do not ship alias-only built-ins such as /img for /attach.
• Command configs may set webui_hidden: true to stay resolvable but be omitted from the chat composer picker.
• Commands contributed by enabled plugins live in their commands/ directory and must not be rediscovered through the generic plugin-distributed path from _commands itself.
• On startup, _commands copies legacy usr/plugins/commands command and skill files into usr/plugins/_commands without overwriting existing files, copies scoped legacy command folders to _commands, and disables the legacy commands plugin roots to prevent duplicate WebUI popovers.
• Script commands must expose run(payload) and return a string or a dict with text and optional effects; show_markdown effects render as auto-dismissing toast notifications.
• Script commands may emit send_message with text to submit the rendered composer text immediately after command resolution.
• Commands accept prefix syntax (/goal objective) and exact postfix syntax (objective /goal); ordinary mid-sentence mentions are not invocations.
• WebUI sends resolve through the picker effect path, while backend-originated messages resolve before reaching the agent.
• /stop uses the same shared cancellation operation as the composer Stop button, including progress cleanup and terminal logging.
• Built-in /computer-use on|off emits a bounded computer_use effect. WebUI only directs the user to Host access in A0 Launcher or the same command in A0 CLI; it never changes a Launcher gateway lease from Agent Zero page content.

Work Guidance

• Keep the command storage and route namespace aligned with _commands.
• Preserve unknown command config keys when editing commands.
• Keep built-in source files immutable; user edits must be same-name scope overrides.
• Keep WebUI paths pointed at /plugins/_commands/....

Verification

• Run conda run -n a0 pytest plugins/_commands/tests after backend or command contract changes.
