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

The annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds one genuinely useful piece of context beyond annotations – the organization API key requirement – but says nothing about result ordering, whether the list is capped or paginated, or what happens when there are no seals.

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?

Two short sentences, resource scope front-loaded ahead of the prerequisite. Nothing is wasted, though "most recent" is vague enough that a few more words on ordering would have earned their place.

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?

A zero-required-parameter read tool with full schema coverage and annotations covering the safety profile; the auth requirement is the main missing piece an agent needs and it is present. Only return-shape details (ordering, pagination) are absent, which is minor here.

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%: the single limit parameter carries its range (1-200) and default (50) in the schema. The description adds no meaning beyond that, so the baseline of 3 applies.

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?

"Your most recent content seals" identifies the resource and a recency scope, and implicitly separates it from the mutation siblings (seal_content, seal_revoke, seal_verify). However, it never states the action (list/retrieve) and "most recent" is left undefined, so the agent must infer that this is a listing tool.

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?

No when-to-use guidance and no mention of alternatives such as seal_verify for checking a specific seal. The only operational note is the API-key prerequisite, which is a requirement rather than usage guidance.

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