printer_api_catalog

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds that the catalog enumerates R/W endpoints and can return full operation definitions, which is useful context beyond the annotations, but says nothing about size, pagination, or whether the catalog is static or dynamically derived.

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 tight sentences with the primary capability front-loaded, followed by the drill-down instruction. No filler, though it could be marginally more explicit about the no-parameter discovery mode.

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 must carry return-value burden, and it only gestures at 'operation details and definitions' without describing the shape of a catalog listing versus a single-endpoint detail response. Adequate for basic invocation but incomplete for an agent planning multi-step API exploration.

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%: the endpoint parameter has a description that usefully ties back to the catalog ('Exact endpoint template from printer_api_catalog'), while the api enum is undocumented. The description corroborates the two-phase pattern but adds no syntax or format detail beyond the schema.

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?

States a specific verb and resource: 'Inspect all documented local S5 printer/cluster R/W endpoints and schemas.' An agent can tell this is a discovery/catalog tool for the printer API. It does not, however, explicitly differentiate itself from siblings like printer_api_read or printer_api_write, which is the remaining gap.

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?

The phrase 'Specify api + endpoint to include operation details' implies a two-phase drill-down workflow, but there is no explicit when-to-use guidance and no mention of when to prefer this over printer_api_read or printer_api_write. Usage is inferable rather than stated.

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