What
The explorer subagent is now explicitly barred from the mcp__plugin_claude-test_browser__claude_test_allow MCP tool, on top of its existing Read/Grep/Glob-only restriction.
The author and runner subagent definitions both gained an explicit name field (author and runner respectively) in their frontmatter.
The runner's "browser helper not loaded yet" fallback message was replaced with a static, more actionable error that names a likely cause: a duplicate, non-built-in Claude Test plugin.
Why
These changes make the plugin's subagents more predictable (the explorer can no longer reach a browser-allow tool it shouldn't need) and easier to identify and debug (explicit names, a clearer failure message) when something goes wrong.
