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

With no annotations, the description carries the full behavioral burden. It does disclose useful traits: it returns the 'current public' version (version currency and public-only scope) and the 'complete Markdown guidance' (return content). However, it omits access requirements, error behavior for missing or private skills, and any rate-limit or permission 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; every clause contributes. It is appropriately terse for a simple getter, though it is arguably too sparse to be fully self-sufficient.

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 one-parameter read tool with no output schema and no annotations, the description explains what is returned (Markdown guidance) and the scope (current public version). It still leaves key context uncovered: the parameter's meaning, how to discover skill_id via search_skills, and any access/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 0%, so the description must compensate, but it never mentions skill_id or how to obtain one. The schema's regex pattern conveys the ID format structurally, yet the description adds no semantic meaning about the parameter beyond what the raw pattern implies.

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 ('Read') and a well-defined resource ('the current public skill version and its complete Markdown guidance'), so an agent immediately understands it fetches one skill's content. It does not explicitly distinguish itself from the sibling search_skills, but the singular 'skill version' phrasing implies single-ID retrieval.

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 prerequisites, and no mention of the search_skills sibling for discovering a valid skill_id. Usage is only vaguely implied by the verb 'Read', leaving the agent to infer the lookup workflow.

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