Get company logo for an invite

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

Annotations already provide readOnlyHint, idempotentHint, and non-destructive nature. The description adds that it is a GET operation and public authorization, but does not disclose potential error cases or response format. Does not contradict annotations; annotation_contradiction is false.

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 very concise (two sentences) and front-loads the purpose. It could be slightly longer to cover parameters, but for what it contains, it is efficient and avoids unnecessary detail.

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 low schema coverage, the description does not compensate by explaining the token parameter. It also does not clarify whether the logo is for the invite's company or another entity. The presence of an output schema reduces the need to explain return values, but overall completeness is lacking.

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%, and the description does not explain the 'token' parameter at all. The parameter is only defined in the schema as a required string with no further context, leaving the agent unclear on what token is expected.

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 title and description clearly state the action (Get) and resource (company logo for an invite). However, it does not explicitly differentiate from sibling invite tools like pc_get_invites_by_token, which also retrieves invite data, but the purpose is sufficiently clear.

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 mentions 'Authorization class: public', indicating it can be used by anyone. But there is no guidance on when to use this tool versus alternatives (e.g., other invite tools), nor any prerequisite or context for usage.

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