 Claude Code has no separate "rules" concept for plugins — `plugin.json` recognizes no `rules` key, and a `CLAUDE.md` at the plugin root is not loaded. Ship guidance as skills and their reference files.
 
+## Agents
+
+Most `flutter-*` plugins ship a per-plugin agent at `agents/<plugin-name>.md`, auto-discovered by Claude Code (no `agents` key in `plugin.json`). The agent is a **thin wrapper over the plugin's existing skills** — it never duplicates convention content. Conventions stay in `skills/<plugin>-usage/references/*.md` as the single source of truth.
+
+Conventions for these agents:
+
+- **Name** = plugin name; invoked `@<plugin-name>` (e.g. `@flutter-navigation`). No collision with skills, which use `/<skill-name>`.
+- **`skills:` frontmatter preloads only the `<plugin>-usage` router** (the small routing skill), not its references. The system-prompt body instructs the agent to inspect the project and lazy-load only the matching reference — preserving progressive disclosure.
+- **`description`** scopes the agent to substantial, multi-step work; the `/<plugin>-usage` skill remains the path for quick inline questions.
+- **Tools:** editing plugins use `Read, Glob, Grep, Edit, Write, Bash, Skill`.
+- **`model`** is omitted everywhere (inherits the session model).
+- No agent for `lean-core` (marketplace meta) or the MCP-integration plugins `flutter-patrol` and `flutter-marionette` — those are backed by their own separate tools/repos, so a wrapper agent there is premature.
+
+These agents are Claude Code only and do not mirror to other targets; keeping them thin over `references/*.md` is what contains that cost.

 Once a plugin is installed, it exposes a `/<plugin-name>-usage` skill — for example `/flutter-bloc-usage`, `/flutter-cqrs-usage`, `/flutter-ui-usage`. Run it to see what the plugin covers, its conventions, and example prompts to try next. It's the fastest way to learn a plugin without reading its full `README.md`. If you're not sure where to begin, run `/lean-core-usage` for a tour of the whole marketplace.

Use the **agent** (`@`) for substantial, multi-step work you want handled end to end in its own focused context: it preloads the plugin's `-usage` skill, inspects the project, and applies LeanCode conventions across several files.

The `lean-core` meta plugin and the MCP-integration plugins (`flutter-patrol`, `flutter-marionette`) ship no agent.
