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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered. The description adds 'owner-scoped' scoping and notes access-policy/runtime constraints, which is some useful context beyond the annotations, but it is vague and partly obscured by unrelated admission-control wording.

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 opening sentence is abstract and not front-loaded with the core action, and the definition is padded with an unrelated aisa-pricing boilerplate block that adds no operational value for an agent trying to call the tool.

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?

An output schema exists, so return values need not be described. However, for a filtering/paginating list endpoint the description never says what is listed or how limit/cursor/status behave, leaving the call semantics under-specified.

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 only 33% and the description mentions none of the three parameters (limit, cursor, status). With low coverage the description should compensate by explaining filtering/pagination semantics, but it adds nothing.

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 reads 'Owner-scoped local asynchronous job lifecycle' – an abstract phrase that never states the actual verb+resource (listing agent runs). Only the title/name imply a list operation. It does not distinguish itself from the singular sibling get_exa_agent_run.

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 when-to-use guidance or routing to alternatives such as get_exa_agent_run (single run) or post_exa_agent_runs (create). The sentence about 'disabling new admission' concerns system behavior, not when an agent should select this tool.

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