Api cwes partial update

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

Annotations declare readOnlyHint=false, idempotentHint=false, openWorldHint=true, destructiveHint=false, so the mutation profile is already covered structurally. The description adds nothing beyond that – no statement of which fields are patchable, whether omitted fields are preserved, or what happens with an invalid/unknown id. The word 'viewed' even implies a read capability this endpoint does not have, though it does not hard-contradict the annotations.

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?

It is one short sentence with zero waste, but that brevity comes from under-specification rather than discipline – no verb, scope, or payload detail is front-loaded.

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, no parameter documentation, and a free-form request body, the description is the only place an agent could learn what a partial update accepts. It delivers none of that, so calling the tool correctly is essentially guesswork.

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 0%: `id` is an untyped-purpose string and `body` is an opaque free-form object with no property definitions. The description supplies no compensating information about the body payload shape or the id format, leaving the agent to guess at the CWE representation.

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 is a generic Django-REST-Framework docstring that says CWEs may be 'viewed or edited' – it never states that this particular endpoint performs a PATCH-style partial update on a single CWE. An agent cannot distinguish it from cwes_retrieve, cwes_update, cwes_list, or cwes_partial_update without inspecting the name suffix.

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 partial update versus full update, create, or destroy, and no mention of prerequisites such as an existing id or required permissions. The 'viewed or edited' phrasing actively blurs the choice between read and write siblings.

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