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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds that the returned content is Markdown guidance, but 'current public skill version' sits uneasily beside the optional version_id parameter and the description never explains that version-selection behavior. No contradiction, but limited added context.

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 no filler. It is efficient, though the 'current public skill version' phrasing introduces ambiguity that a few more words could have resolved.

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 usefully states that complete Markdown guidance is returned, which is good. However, for a 2-parameter tool with 0% schema coverage, the absence of any parameter or version-selection explanation leaves the definition only minimally adequate.

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 0%, so the description carries the full burden for skill_id and version_id, yet it explains neither. The word 'current' faintly implies a default when version_id is omitted, but the ID format and the difference between the two parameters are left entirely undocumented.

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?

Specific verb+resource ("Read the current public skill version and its complete Markdown guidance") clearly states what is retrieved. It does not distinguish itself from siblings like search_skills or get_post, so an agent gets no routing help, but the core action is unambiguous.

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?

There is no when-to-use guidance, no mention of prerequisites (e.g. needing a skill_id from search_skills), and no stated alternatives or when-not-to-use conditions. Usage is only inferable from the name.

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