PATCH /models/{id}

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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is covered structurally. The description adds nothing beyond restating the title: it does not explain PATCH partial-update semantics, what gets overwritten, or that the confirm parameter is required when SNIPEIT_CONFIRM_WRITES=true. With annotations present the bar is lower, but zero added context merits a 2.

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 first sentence is front-loaded and efficient. The second sentence ("Generated from Snipe-IT OpenAPI operation modelsid-2") is metadata noise that consumes space without helping an agent decide or invoke.

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 destructive, open-world PATCH tool with a nested body object and a conditional confirm parameter, the description is too thin. It does not explain the confirm gate, the partial-update behavior, or which body fields are meaningful, leaving significant gaps even though annotations cover the basic write/destructive profile.

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?

The schema documents id and confirm but leaves the seven body properties (name, notes, category_id, fieldset_id, requestable, model_number, depreciation_id, manufacturer_id) undescribed. At 67% top-level coverage, the description could have clarified the body object or confirm semantics but instead provides no parameter information at all.

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 a specific verb and resource ("Update a model") and the title confirms PATCH semantics, so an agent knows this mutates an existing model record. However, it does nothing to distinguish this from the many sibling model-id tools (modelsid, modelsid_1, modelsid_3), which likely cover GET/DELETE or other operations on the same resource.

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 guidance on when to use this tool versus the other model-related siblings, no prerequisites, and no exclusions. The agent is left to infer that this is the PATCH path rather than a GET or DELETE from the title alone.

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