Create Session for Agent

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

Annotations already indicate this is a write operation (readOnlyHint=false) and non-destructive (destructiveHint=false). The description adds 'bound to a specific agent' but does not disclose additional behavioral traits like side effects, permissions, or persistence behavior. It is consistent and adequate for a simple create operation.

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, front-loaded sentence with zero wasted words. It conveys the essential operation and scope effectively.

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?

Given the rich schema (all parameters described), annotations, and the simple nature of a create operation, the description is adequate. No output schema exists, so return values need not be explained. A minor gap is the lack of explicit guidance on when to prefer this over the general session_create tool, but the description covers the core purpose.

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%, and the description does not add significant value beyond what the schema already provides. The phrase 'bound to a specific agent' clarifies the purpose of agent_id but is already implied by the parameter description. Baseline 3 is appropriate.

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 a specific verb ('Create'), resource ('session'), and scope ('bound to a specific agent'). It effectively differentiates from the sibling tool lyzr_session_create by emphasizing the agent binding, which is the key distinguishing factor.

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 usage when a session needs to be created for a specific agent, but it does not explicitly mention alternatives or when not to use it. Given the existence of lyzr_session_create as a sibling, explicit guidance would improve the score.

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