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

Annotations already declare readOnlyHint and idempotentHint, so safety is covered; 'always safe' and 'takes no parameters' largely restate them. The description does add useful context beyond annotations — that it reads a bundled profile without contacting any target or making a network call and returns instantly — but does not describe return format details (left to the output schema).

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 purpose and return contents, followed by usage and alternative routing. Efficient overall, though the 'takes no parameters, is always safe, and returns instantly' clause is somewhat redundant with the annotations.

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?

For a zero-parameter read tool, the description covers purpose, usage, alternatives, and key behavioral traits. Since an output schema exists, enumerating return values is extra rather than necessary, but nothing an agent needs in order to call it correctly is missing.

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 the baseline is 4. The description confirms it takes no parameters, which is accurate but adds no parameter-level meaning since there is nothing 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?

States a specific verb (describe) and resource (this MCP server from its bundled profile), then enumerates exactly what it returns: repository URL, default component set, components grouped by tier, and optional MCP add-ons. It also distinguishes itself from inspect_target by scope (bundled profile vs. machine's live state).

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?

Explicitly says to use it first to resolve a component id for install_component/remove_component/update_component or to view add-ons, and names the alternative inspect_target for a machine's live state. Nothing is left to inference.

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