PATCH /consumables/{id}

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

Annotations already declare destructiveHint=true, idempotentHint=true, and openWorldHint=true, so the safety profile is covered. The description adds nothing beyond the annotation layer: it never warns that the operation is destructive, never notes that name/qty/category_id are effectively required in the body, and never mentions the SNIPEIT_CONFIRM_WRITES guard behavior. "Updates a portion" is the only semantic contribution.

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 short sentences, front-loaded with the endpoint and action, so it is not bloated. But the second sentence ("Generated from Snipe-IT OpenAPI operation consumablesid-1") is provenance boilerplate that does not help an agent, and the whole thing is under-specified rather than tight.

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?

This is a destructive mutation with a nested body object, low schema description coverage, and no output schema. Given that complexity, the description should explain partial-update semantics, required fields, and the write-confirmation flow, and it does none of that, leaving the agent with little beyond the annotations.

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 description coverage is only 33% and the body is a nested object with eleven properties, none explained in the description. The description names no parameters, so the gap in schema descriptions is never compensated; the confirm parameter's semantics and the required body fields must be inferred entirely from 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?

The description states a verb and resource ("Updates a portion of a consumable record") and the HTTP path, so the basic action is clear. However, it is an auto-generated restatement of the endpoint and gives no differentiation from the many sibling consumable tools (snipeit_gen_consumablesid, snipeit_gen_consumablesid_2, snipeit_gen_consumablesidcheckout), so an agent cannot tell which consume-tool to pick without opening schemas.

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?

No statement of when to use this partial update versus the full-update sibling (gen_consumablesid_2) or when not to. The only usage hint is the word "portion", which implies partial-update semantics but never explains that distinction or any prerequisites such as the confirm flag or required body fields.

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