Relay two bots

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

Annotations declare openWorldHint=true and readOnlyHint=false, so safety is partly covered; the description adds real value by disclosing termination behavior (maxTurns default 4, cap 20, stop_relay, human can interrupt between turns). It does not say the call blocks sequentially per reply or what happens on timeout.

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?

Three tight sentences: purpose first, then the relay mechanism, then termination conditions. No redundant restatement of the title and nothing wasted.

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?

With no output schema and a non-read-only, open-world tool, the description should say what is returned (collected replies per bot?) and how threadId affects the run. It covers termination well but leaves the result shape and threading behavior unstated.

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?

Coverage is 50%; the description clarifies the roles of fromBot (receives the opening message) and toBot (receives each reply), which the schema does not. maxTurns semantics are restated from the schema, and threadId and timeoutMs are not addressed at all.

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 verb and resource ("Run a multi-turn conversation between two configured bots") and explains the alternating relay mechanism, which separates it from one-shot siblings like send_message. It stops short of explicitly naming alternatives such as broadcast_message.

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?

Usage is only implied: the mention of maxTurns and stop_relay tells the agent how the run terminates, but there is no explicit statement of when to choose this over send_message, broadcast_message, or wait_for_reply.

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