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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive). The description adds genuine but cryptic behavior: 'Owner-scoped', reads/cancellation surviving admission disable, and access-policy gating. These are beyond the annotations, but they are vague policy statements rather than actionable behavior for a single-run fetch.

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?

Brief but poorly front-loaded: the opening sentence names a 'lifecycle' rather than the operation, and the tool embeds an irrelevant pricing boilerplate block that consumes space without helping an agent 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 explained. However, for a simple get-by-id tool the description still omits the core operation, any hint about jobId, and any usage context, leaving the definition materially incomplete.

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 0% and the description says nothing about jobId — not its format, where it comes from, or whether it is owner-scoped/URL-safe. With only one parameter and zero documentation anywhere, the description fails to compensate for the coverage gap.

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 never states the operation. It talks abstractly about 'local asynchronous job lifecycle' and admission policy, but never says it retrieves the details/status of a specific Exa agent run identified by jobId. The title ('Exa Agent Runs detail') carries more purpose than the prose, and an agent cannot distinguish this from sibling getters like get_exa_apis_v1_exa_agent_runs or get_firecrawl_crawl_job.

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?

No when-to-use guidance and no mention of alternatives. With ~37 siblings including several job-detail getters and a cancel endpoint, the description offers nothing to route the agent between reading a run, listing runs, or cancelling one.

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