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 useful value by disclosing what the read returns (settings, lifecycle, recorded outcome), but says nothing about behavior for unowned or missing jobs, error conditions, or access requirements.

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?

A single front-loaded sentence with no filler; the object of inspection and the returned facets are stated immediately.

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?

For a one-parameter read tool with no output schema, the description is largely sufficient: it names the return facets and the annotations carry the safety profile. It stops short of explaining error behavior for non-owned or unknown job IDs, which would round it out.

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 coverage is 100% and the single 'job' parameter is fully documented as the UUID of a job owned by the API key's workspace. The description's word 'owned' reinforces that ownership scoping but adds no format or lookup guidance beyond the schema, so the baseline 3 applies.

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 uses a specific verb ('Inspect') on a specific resource ('a training job') and enumerates what is surfaced: settings, lifecycle and recorded outcome. That distinguishes it from the list-style sibling emt_training_jobs and the event-stream sibling emt_training_events, though neither is named explicitly.

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 when-to-use or when-not-to-use guidance and no naming of alternatives; the agent must infer that emt_training_jobs lists jobs while this one fetches a single job's detail. The only implicit constraint is 'owned', which is already stated in the schema.

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