manage-tools

Manage the ## External Tools section in AGENTS.md. This section lists the tools the agent should know about: agent skills that are invoked frequently, MCP servers connected to the project, and CLI tools the project depends on for non-obvious workflows.

Philosophy. Tools that are on-demand or obvious do not belong here. The agent already discovers most tools at runtime. This section is for tools that are shared team conventions — "when you need issue tracking, use gh", "when you need the database, use the postgres-readonly MCP" — that a new agent would otherwise miss.

Scope

In scope:

• Add/remove/refresh entries in ## External Tools
• Auto-detect candidate tools from .mcp.json, package.json, Brewfile, mise.toml, .tool-versions, and ~/.claude/agents/
• Present candidates as a checklist (user opts in per item)
• Enforce the 3-category structure: ### Agent Skills, ### MCP Servers, ### CLIs
• Drift detection on re-run: compare current section to detected tools and propose add/remove operations

Out of scope:

• Installing or configuring the tools themselves (this skill only documents them)
• Listing every installed dependency (only shared team conventions that the agent must know)
