verify_job

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

The description says the tool will "save its observed progress," which is a persistence/mutation side effect that conflicts with the supplied readOnlyHint=true annotation; only idempotency (repeat verification against fresh telemetry) is consistent with the annotations. The non-destructive clarifications ("Never submits or retries a print") and the route-override behavior add real value, but the save semantics contradict the declared read-only profile.

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?

The purpose is front-loaded and the sentences are short, but the sequence is choppy and "Layer 0 is preparation" is unexplained jargon that does not obviously earn its place for an agent with no pipeline context.

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?

With no output schema, the description should say more about what a verification produces (or what happens on a name mismatch), and "Layer 0" is never defined. It does cover the key safety property and route semantics, so it is adequate but leaves real gaps for a two-parameter job-verification tool.

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 50%: route is already documented in the schema, and the description adds genuine meaning (the override lets a LAN print be monitored via cloud, so LAN reachability is not required). However, job_id has no schema description and the text only says "Exact job-name match required," which muddles rather than clarifies a parameter named job_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?

"Verify a submitted job against fresh printer telemetry and save its observed progress" names a specific verb (verify) and resource (submitted job), which distinguishes it from get_job (retrieve stored state) and print_job (submit). It does not name the siblings it differs from, so an agent still has to infer the boundary, but the core action is unambiguous.

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 one negative constraint ("Never submits or retries a print") that tells the agent not to use this for printing, but no positive guidance on when to call verify_job instead of get_job or printer_status, and no prerequisites or ordering stated beyond the cryptic "Layer 0 is preparation." The agent must guess at the workflow position.

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