start_agent_pairing

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

With no annotations, the description carries the full behavioral burden. It discloses that the tool initiates an owner-approval flow and returns an approval_url and request_secret, including a clear security directive. It doesn't cover state changes or failure cases, but the essential behavior is disclosed.

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 with the main action front-loaded. Every word earns its place, and the security note is essential guidance tightly packed.

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?

The description tells the agent what to do and how to handle secrets, but omits requested_access semantics and any follow-up pairing step. An output schema exists to cover return structure, but the missing parameter explanation and lack of flow context leave gaps.

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 needed to explain agent_name and requested_access. It does not define either, only referencing 'this agent' generically. The output fields approval_url and request_secret are described, but the input parameters are left undocumented.

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 action ('Request owner approval for this agent') with a specific verb and target. It doesn't reference sibling tools like exchange_agent_pairing to differentiate, so it misses the top score, but the purpose is 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?

No guidance is provided about when to use this tool versus alternatives such as exchange_agent_pairing, invite_person, or start_account_signup. No prerequisites, exclusions, or follow-up steps are mentioned, leaving the agent to infer the appropriate context.

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