get_sessions

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

No annotations are provided, so the description carries the full burden. It correctly implies a read-only listing operation and adds context about session semantics, but it does not explicitly state read-only behavior, pagination, or potential limitations. This is adequate but leaves some gaps.

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 two short sentences that immediately front-load the action ('List agent sessions') and provide only essential context. Every sentence contributes value without redundancy.

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 tool is simple, has an output schema (so return values are covered), and the description explains the purpose and domain context. It lacks explicit usage scenarios or exclusions, but for a straightforward list operation with one optional filter, it is largely 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 the single optional parameter 'agent_name' is already documented. The description adds no parameter-specific meaning beyond what the schema provides, warranting the baseline score of 3.

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 states 'List agent sessions from Itential Platform' with a specific verb+resource pair. It also explains what agent sessions are and when they are created, which distinguishes it from sibling tools like 'describe_session' (list vs. describe) and 'get_agents' (sessions vs. agents).

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 provides clear context on when agent sessions are created (via endpoint triggers) and what information they record, making the use case evident. However, it does not explicitly name alternative tools or specify when not to use this tool, so it falls short of a 5.

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