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

No annotations are provided, so the description carries the full burden. It does disclose that the payload covers 'limits' and 'exactly what you as an assistant can and cannot do here', which is meaningful boundary information. However it never states that this is a side-effect-free read, whether the result is stable/cacheable, or anything about cost, so a mutation-safe call must be inferred.

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?

Two sentences, no filler, and the payload list is front-loaded before the conditional use instruction. Every clause carries information.

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 and no annotations, the description does the right thing by enumerating the contents the agent will receive (services, materials, turnaround, limits, permissions). It is complete enough to justify calling it as a primer; only the read-only/side-effect profile is left implicit.

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?

Zero parameters, so there is nothing to disambiguate and the baseline of 4 applies. The description correctly adds no fake parameter talk.

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 states exactly what the tool returns: services, materials, turnaround, limits, and the assistant's own permission boundaries. That is specific and self-evident, and 'Read this first' implicitly separates it from the transactional siblings (submit_job, check_order). It stops short of naming any sibling explicitly, so it is clear but not differentiating in the way a 5 requires.

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?

'Read this first if you have not worked with this shop before' gives an explicit triggering condition for use, which is more than most definitions offer. It does not name alternatives or state when-not to call it (e.g., skip once cached), so the guidance is clear context rather than full routing.

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