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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is fully covered. The description adds that the response includes history, which is genuinely useful context, but says nothing about permissions, visibility scope, or failure behavior for an unknown job_id.

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?

Five words, no filler, and the most informative qualifier ('Full...incl. history') is front-loaded. It is arguably too terse for a retrieval tool, but nothing is wasted.

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 rich annotations this is close to adequate, and the hint that history is returned partly compensates for the absent output schema. Still, an agent gets no sense of the response shape beyond 'details' and 'history'.

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% with a single required job_id, so the schema carries the parameter documentation. The description adds no syntax, format, or sourcing detail for job_id, which is the baseline expectation at this coverage level.

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 title plus description identify a specific verb+resource: fetch a job's full details. The word 'Full' implicitly distinguishes it from list_jobs and review_job by signaling a complete single-record fetch, though no sibling 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 when-to-use guidance and no mention of alternatives such as list_jobs for enumeration or review_job for judging a job. The agent must infer from the name alone that this is the single-record retrieval path.

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