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

No annotations are provided, so the description carries the full burden. 'Get' implies a safe read, and the field list (readme, tools, permissions, ratings) signals the shape of the payload, but there is no mention of auth requirements, rate limits, or whether details are cached/live.

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?

A single front-loaded sentence with an em-dash list of returned fields; no filler, no redundancy.

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 output schema, the description partially compensates by enumerating the payload (readme, tools, permissions, ratings). For a one-parameter read tool this is close to sufficient, though it omits any note on the ID source or error behavior.

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?

Schema description coverage is 100% for the single skill_id parameter, so the schema already documents it. The description adds no syntax, format, or ID-provenance detail beyond what the schema provides, matching the baseline 3.

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 ('Get') and resource ('full details of a marketplace skill') and enumerates the fields returned. It does not explicitly name a sibling to contrast with, but the scope is unambiguous and an agent can distinguish it from list-oriented tools like browse_marketplace.

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?

Usage is only implied: the schema's parameter note ('Skill ID from browse_marketplace') hints that this follows a browse step, but the description itself never states when to use this rather than browse_marketplace or another detail tool.

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