club_call_agent

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

With no annotations, the description carries the full behavioral burden. It usefully discloses that the club acts as a directory and optional proxy, but it does not mention whether calling the target agent can cause side effects, what error behavior looks like, or whether authorization is required.

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 sentences with no filler; the purpose is front-loaded and followed by a concise workflow. Every sentence adds useful information.

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?

There is no output schema and no annotations, and this tool performs a remote call that could have side effects. The description does not clarify return behavior, error modes, or how direct agent_id changes the discovery-vs-call flow, leaving important gaps for confident invocation.

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 100%, so the baseline is 3. The description adds a light workflow relationship (capability drives discovery, then endpoint and call) but does not substantially deepen the semantics of payload or agent_id beyond the schema.

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?

States a specific action ('Discover and call another agent') and resource ('AiTop Club'), then breaks down the workflow into capability search, endpoint retrieval, and call. The 'directory and optional proxy' phrase also helps distinguish this from discovery-only sibling tools like club_search.

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 for when you need to find and invoke an agent through the club, but it does not explicitly state when not to use it or name alternatives like club_search or firmy_ask. No exclusion criteria are provided, so the agent must infer routing.

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