ai:agent type:review

Review every Claude Code subagent file for the tools it can actually reach: agents with no tools line inherit every built-in and MCP tool, lookalike fields such as allowed-tools are ignored, and reviewers that can write or run a shell. Proposes a narrower tools line. Use when asked \"which of my subagents can use the GitHub MCP tools?\", before adding an MCP server or after installing a plugin with agents. Not for permission rules (permissions-builder) or for skills (skill-supply-chain-review).

From the source SKILL.md

A subagent is a Markdown file with front matter. Its tools line decides what it can use, and the default is generous: a file with no tools line inherits every tool available to subagents, including every tool of every MCP server the session connects. People have asked for MCP tools to be scoped to one subagent (anthropics/claude-code issue 6915, 89 reactions), and the documented answer is in the agent file itself: list tools, list mcp__<server>__<tool> names, or withhold servers with disallowedTools. In practice agent files are copied from examples, lookalike fields from skills…
