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 fully covered. The description adds value by specifying what the read returns (model, dataset, training settings), but says nothing about behavior when the job is not owned by the workspace or what the recipe's form is (config blob, file, structured object).

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?

One sentence, front-loaded with the verb and resource, with the returned content appended rather than buried. No filler, no redundancy with the schema.

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-only tool with full schema coverage and no output schema, the description adequately states purpose and hints at return contents. It falls slightly short by not characterizing the recipe's structure or the failure mode for unauthorized jobs, which matters because there is no output schema to fill that gap.

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 'job' parameter is already fully documented as a UUID of a workspace-owned job. The description's phrase 'owned training job' reinforces the ownership scoping but adds no syntax or format detail 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 gives a specific verb ('Read') and a specific resource ('the reproducible recipe for an owned training job'), plus the payload contents (model, dataset, training settings). It does not, however, distinguish itself explicitly from the close siblings emt_training_job / emt_training_jobs, leaving the reader to infer that 'recipe' differs from 'job details'.

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 / when-not-to-use guidance and no named alternative, despite a crowded sibling set containing emt_training_job, emt_training_jobs and emt_training_events. The only usage signal is the implicit prerequisite 'owned training job', which the agent must derive rather than being told.

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