Get skills index for an invite

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

Annotations already declare `readOnlyHint: true`, `destructiveHint: false`, and `idempotentHint: true`, which convey safety and idempotency. The description adds the HTTP method and authorization class, but no additional behavioral traits beyond what annotations provide.

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 short—two sentences covering purpose and endpoint details. It is concise but could be more informative without adding much length.

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?

Despite having an output schema, the description lacks essential context: it does not clarify what a 'skills index' contains, how to use the parameter, or when to invoke this tool. The missing parameter semantics and usage guidance make it incomplete for an agent to reliably select and use it.

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?

The input schema has one required parameter `token` with no description. The description does not explain the parameter's purpose, format, or how to obtain it. With 0% schema coverage, the description fails to compensate, leaving the parameter's semantics undefined.

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 states 'Get skills index for an invite,' clearly indicating the verb and resource. However, it does not explain what 'skills index' means or how this tool differs from other invite-related siblings like `pc_get_invites_by_token` or `pc_get_invites_by_token_skills_by_skill_name`, leaving some ambiguity.

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 guidance is provided on when to use this tool versus alternatives. The sibling list includes several invite-token tools, but the description offers no context, exclusions, or selection criteria.

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