Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already cover readOnly/idempotent/non-destructive, yet the description adds genuine behavioral detail: risco-rated servers route to deniedMcpServers, expired or unchecked items are excluded, and the URL/?* wildcard semantics for route matching. That is more than the annotations provide.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the core output (managed settings), followed by supporting clauses about wildcard matching, exclusion rules, and the `comandos` output. Dense but each sentence carries output-shape information; no obvious filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no parameters and no output schema, the description must explain the returned structure, and it does: managed_settings, allowManagedMcpServersOnly, deniedMcpServers routing, and comandos. An agent knows what it will get and why items are included or excluded.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Zero parameters, so there is nothing for the description to disambiguate; baseline 4 applies. Schema coverage is 100% with no params to document.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states the resource clearly: it produces the watch list rendered as Claude Code managed settings (allowedMcpServers/deniedMcpServers) plus `claude mcp add` commands. The action verb is implied rather than stated ('The watch list as...'), and it does not differentiate itself from siblings like list_watched_tools, but an agent can grasp what it emits.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit when-to-use framing, prerequisites, or named alternatives. It references `docs` and describes output fields, but never says when this tool should be chosen over list_watched_tools or similar siblings.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
