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

The readOnlyHint=true annotation already establishes that this is a safe read operation, and the description adds that it returns the full body of one skill. It does not describe error behavior for unknown skill names, output structure, or other operational details, which is acceptable but leaves meaningful gaps.

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 wasted text. It immediately states the action, scope, and key input.

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 simple single-parameter read tool with full schema coverage and readOnly annotations, the description is largely complete. It could be slightly richer by clarifying the relationship to skill files or listing tools, but nothing critical prevents correct invocation.

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%, so the name parameter is already documented as 'The skill name, as listed by list_skills.' The description's phrase 'by name' adds no syntax or formatting detail beyond what the schema provides, making the baseline score appropriate.

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 gives a specific verb and resource: 'Load the full body of one skill by name.' It clearly distinguishes loading a single skill from listing skills, though it does not explicitly contrast with the sibling get_skill_file.

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?

The intended use is implied by 'Load the full body of one skill by name,' but the description does not state when to use this tool versus list_skills, get_skill_file, or list_skill_files. The schema mentions list_skills, but the description itself gives no explicit routing guidance.

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