get_skill

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

With no annotations, the description carries the burden. It communicates a read-only operation via 'Fetch' and that it returns 'full content', but it does not disclose behavior around missing IDs, version semantics (integer vs version ID), or the role of agent_key. No contradiction with annotations exists.

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?

The description is a single, front-loaded sentence with no filler. It communicates the core action in 12 words, making it easy for an agent to parse.

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?

The description is minimal but adequate for a simple get tool; however, it leaves significant gaps around the optional parameters (especially agent_key) and how this tool relates to search_skills and listing tools. The output schema exists, so return format is not required, but the parameter semantics gap hurts overall completeness.

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 clarify parameters. It explains 'id' and 'version' indirectly, but omits 'agent_key' entirely and uses the phrase 'version id' which conflicts with the schema's integer 'version' type. The description does not add enough meaning beyond the bare schema names.

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 uses a specific verb 'Fetch' with a clear resource 'the full content of a skill' and identifies key identifiers ('id or version id'). This distinguishes it from siblings like delete_skill, search_skills, and update_skill, which focus on different actions.

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?

It implies usage when the agent already has a skill ID or version ID and needs the full content, but it does not explicitly state when to prefer this over search_skills or list_* tools, nor does it mention any exclusion criteria or alternatives.

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