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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds genuinely useful behavioral context by enumerating the exact status values the agent can expect and noting a FIX verdict field, though it does not explain what the verdict means, whether statuses are terminal, or what happens 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?

A single front-loaded sentence that spends its words on the return-value domain rather than restating the name. Nothing is wasted and nothing is buried.

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 usefully enumerates the return values, which is the main thing an agent needs. The remaining gap is the unexplained 'FIX verdict' concept and the lack of provenance for job_id.

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?

With a single parameter and 0% schema description coverage, the schema gives only an integer type and minimum of 1. The description implies the parameter identifies 'a job' but adds no guidance on how to obtain a job_id (e.g., from post_job or accept_job) or what happens on an invalid id.

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?

Specific verb+resource ('Get the status of a job') with a concrete enumeration of the status domain (queued, running, delivered, refunded) plus the FIX verdict. It implicitly separates itself from sibling get_snapshot_status by operating on jobs rather than snapshots, but never names or contrasts that sibling 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 statement of when to call this versus alternatives (get_snapshot_status, accept_job, deliver_job), nor any prerequisite such as where a job_id comes from or which lifecycle stage makes polling meaningful. Usage is only inferable from the verb.

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