Identify Session Agent

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

Annotations already declare readOnlyHint=false and idempotentHint=false, signaling a state-changing, non-repeat-safe operation. The description adds the useful consequence that it sets role and scopes tools, but does not disclose what happens on repeat identification, whether the session is bound to the key, or auth/permission requirements beyond what the schema implies.

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, no filler, with the core action front-loaded and the side effect second. Every sentence earns its place.

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?

No output schema exists, so return values needn't be explained, and params are fully covered by the schema. However, for a non-idempotent session-establishing tool, the description leaves the role/scoping mechanics and repeat-call behavior entirely unstated, so it is only minimally 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?

Schema description coverage is 100%, so agent_id, public_key, and private_key are already documented in the schema, including that private_key is for signing. The description adds no param-level detail. Baseline 3 is appropriate when the schema carries the 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?

States a specific action and object: 'Identify yourself to the coordination server.' The second sentence adds the effect (sets your role, scopes tools). It is clear but does not distinguish itself from related siblings like get_my_role or register_agora_agent, which an agent might confuse it with.

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?

There is no explicit statement of when to call this versus alternatives, nor prerequisites (e.g., call at session start, before other scoped calls). 'Identify yourself' implies an opening handshake but it is left to inference. No when-not guidance or alternative tooling is named.

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