Api presets save draft partial update

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

Annotations already disclose readOnlyHint=false, openWorldHint=true, idempotentHint=false and destructiveHint=false, so the safety profile is partly known. The description adds zero behavioral context: it does not say what a 'draft' is, whether the save overwrites prior draft content, or what state the preset must be in.

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 brief, but only because it is under-specified rather than economical: the entire text is the tool's own name, with no front-loaded statement of action or scope.

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 non-idempotent, open-world mutation with no output schema and an effectively undocumented payload, the description supplies nothing an agent needs to invoke it correctly. The draft lifecycle semantics implied by the name are entirely unexplained.

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 0% and the single parameter is an opaque 'id' with no type context beyond 'string'. The description does not clarify whether this is the preset id, a draft id, or a revision id, nor what the partial payload should contain (the schema in fact lists only 'id').

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 nothing but the snake_case identifier restated as prose ('api_presets_save_draft_partial_update'), which is a tautology of the name. An agent can vaguely infer a draft-saving partial update on 'presets', but no verb+resource statement explains what is actually saved or on which object.

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 call this versus the many sibling draft tools (presets_start_editing_create, presets_publish_draft_create, presets_discard_draft_create, presets_partial_update). No prerequisites, no exclusions, no alternatives.

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