agent_mesh_invite

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

With no annotations, the description carries the full burden for behavioral disclosure. It adds valuable details: single-use and 15-minute validity. Yet it omits other aspects like permissions required, whether existing invites are invalidated, or what the response contains. The absence of these details leaves the agent without a complete safety/behavioral profile.

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 sentence, front-loaded with the verb and core resource. It is efficient and easy to parse. However, the sentence ends abruptly with 'ag...', suggesting truncation, which slightly undermines the structural completeness.

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 zero-parameter tool with no output schema, the description covers the essential purpose and key constraints (single-use, 15-minute validity). Still, it does not explain how this fits into the broader mesh flow (e.g., that agent_mesh_join consumes the code), and the truncation leaves the context incomplete. A fully articulated alternative reference would make it more complete.

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 tool has zero parameters, which per rubric is a baseline 4. The description appropriately says nothing about parameters because none exist. No additional semantic meaning is needed beyond what the empty schema already conveys.

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 tool creates a 'single-use pairing code' with a specific intent to be redeemed by another machine. This is distinct from sibling tools like agent_mesh_join (which presumably redeems) and agent_mesh_revoke (which revokes). The verb 'Creates' and resource 'pairing code' make the purpose unambiguous.

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 phrase 'another of the user's machines can redeem' implies the use case of pairing a new device, and the 15-minute validity hints at time-sensitive usage. However, there is no explicit 'use this when' or mention of alternatives (e.g., agent_mesh_join for redemption), and the truncated ending 'ag...' suggests incomplete guidance.

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