Build, improve, review, or troubleshoot Agent Zero plugins for local use or community distribution. Follow plugin structure and installation rules, verify behavior in the target runtime, and prepare repository and Plugin Index contributions when requested.
Build, improve, review or publish Agent Zero plugins; local or community, with focused references.
Review the instructions the agent will receive before you install.
Use this entrypoint to build or improve a plugin, review it, or prepare community contribution. For finding useful existing plugins and installing/updating them, use a0-manage-plugin.
Honor an explicit local-only or community-contribution request. For a new plugin, if the user has not said which, ask once: "Should this stay local, or be prepared for community contribution?" Do not ask again when the answer is already in the conversation. For an existing plugin, inspect its location/repository and requested outcome; clarify only an unresolved distribution choice.
/a0/usr/plugins/<name>/. No public repository or Index submission needed.references/contribute.md./a0/plugins/.Plugin setup, dependency installation, required initialization, and uninstall cleanup MUST use lifecycle functions in the plugin-root hooks.py. Never put these operations in execute.py, and never require an Execute button or manual post-install command to make a plugin usable.
install() prepares dependencies and initializes the plugin automatically after installation and again after updates. Make it safe to rerun.pre_update() stops plugin-owned processes or prepares state before an update when needed.uninstall() stops plugin-owned processes, removes registrations, and removes plugin-owned dependencies/resources before the framework deletes the plugin directory. Preserve shared dependencies and unrelated user data.hooks.py; it may delegate to plugin-local helpers. If boot-time initialization is needed, a startup extension may call the same helper or hook; it does not replace install/uninstall hooks.execute.py unless there is a separate, explicitly requested manual operation unrelated to setup, dependency installation, required initialization, updates, or removal.After loading this skill, use skills_tool with action: "read_file", skill_name: "a0-create-plugin", and the reference path:

| Channel integrations: shared slash commands, effects, menus, authorization | references/channel-commands.md |
Alpine stores, settings UI, x-overflow controls, notifications, custom message/process-step handlers | references/webui.md |
| Review existing code or verify a completed change | references/review.md |
| Standalone repository, license, Index entry, validation and PR | references/contribute.md |
/a0/AGENTS.md, /a0/plugins/AGENTS.md, and the closest applicable contracts.plugin.yaml at the plugin root. Use stable underscore names for new custom plugins. Keep credentials and runtime state out of published source.references/review.md before declaring the work complete; report actual checks and remaining limitations.Follow the first failing boundary: root plugin.yaml and correct directory; global/project/profile toggle and effective config; imports in the framework runtime; API auth/CSRF and route; extension path/breakpoint; store import and gate. Inspect the relevant server/browser error before editing. Use management APIs for lifecycle refreshes; do not manually rerun install/uninstall hooks as a diagnostic or delete state to hide the failure.
Report the feature, usage, live verification, and any unresolved limits. For community work, distinguish repository publication, PR creation, CI results, and actual merge. Follow an existing request to commit or publish; otherwise keep changes ready for review.

Create specialized Agent Zero profiles by defining their roles, working methods, and delegation criteria. The skill prepares configuration files and instructions, with optional custom tools, extensions, and model preset selection when needed.
Operate Agent Zero projects, chats, and tasks, or develop new tools, extensions, and API features. The skill guides work through existing APIs, relevant documentation, current source code, and checks appropriate to the change.
Find Agent Zero plugins that match a task, compare candidates and their requirements, and manage installation, updates, settings, activation, and removal. It also supports security scans and checks the resulting plugin state through framework management APIs.
Automate web page tasks such as clicking, filling forms, uploading and downloading files, and taking screenshots. Work across tabs using a browser on the connected host machine or inside a Docker container.
Create, edit, and install extensions for Agent Zero Browser, including extensions from Chrome Web Store. It guides permission reviews and checks for suspicious behavior, with new extensions built as readable files that users can inspect.
Fill and submit web forms with dropdowns, checkboxes, radio buttons, file uploads, and directly editable fields. Check unclear fields before acting, inspect visual states when needed, and verify the result after submission.
