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

Annotations declare readOnlyHint=true and destructiveHint=false, but the description says 'Publish' which implies a mutating action. This is a potential contradiction: publishing likely creates a public page, which is not read-only. The description also lacks details such as idempotency, whether it can be undone (though unpublish exists), or the resulting URL format beyond the schema's '/p/{id}'. Given the mutation implication, the description does not add sufficient transparency and may even conflict with annotations.

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, concise sentence that states the purpose and a key behavioral note. It is front-loaded with the core purpose and the extra clause caps it off without waste. Ideal length for this tool.

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?

Given the tool's simplicity (one parameter, no enums) and that an output schema exists, the description is reasonably complete. However, it lacks clarity on whether publishing is reversible or what the exact outcome is (e.g., updating an existing page). The sibling unpublish_generation implies reversibility but is not mentioned. For a publishing action, a bit more context would be helpful.

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 coverage is 100%, so the clipId parameter is fully documented in the input schema. The description adds no extra semantic meaning about the parameter beyond what the schema provides. Per the rubric, baseline of 3 is appropriate when schema covers parameters well.

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 clearly states the verb 'Publish' and the resource 'completed library generation', which is specific enough. It also adds a distinguishing detail ('Does not use extra allowance') that hints at a difference from other publish/quote tools, though it doesn't explicitly name a sibling. Given the large sibling list, some differentiation is helpful but could be stronger.

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 description implies the tool is for publishing completed generations and mentions it doesn't use extra allowance, which suggests when to use it (when no extra allowance is desired). However, it does not explicitly state when NOT to use it or mention alternatives like unpublish_generation or other publishing tools. The clear context is there, but exclusions are missing.

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