Respond to an invitation

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

It adds the behavioral detail 'verified by read-back,' which is useful and goes beyond the schema. But with no annotations provided, the description carries the full burden; it does not disclose side effects, permission requirements, irreversibility, or what the read-back verification entails.

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 filler. Every phrase earns its place: the action set, the resource, and the read-back verification.

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 two-parameter tool with an enum, the core behavior is covered and the read-back detail adds useful context. However, with no output schema and no annotations, the description omits return-value expectations and usage caveats, leaving some gap for an agent deciding whether this is the right tool.

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%, so the description must compensate. It repeats the action enum values but does not explain the 'invitationUrn' parameter's format, ownership, or relationship to the invitation lifecycle. The agent is left to infer most of the parameter's meaning.

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 specific verbs ('accepts, ignores, or withdraws') and a concrete resource ('connection invitation'), making the tool's purpose immediately clear. It differentiates from siblings like connect or remove_connection by its unique action set, though it does not explicitly name alternatives.

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 used when a connection invitation needs to be accepted, ignored, or withdrawn. However, it provides no explicit guidance about when not to use it or how it compares to sibling tools such as connect, get_invitations, or remove_connection.

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