Get brand kit

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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds nothing beyond that: it does not say what happens with an unknown or malformed brand_id, whether a not-found error versus empty result is returned, or what fields a brand kit actually contains.

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?

A single short sentence with the retrieval scope front-loaded and zero padding. It is efficient, though the extreme brevity leaves room to add one clarifying clause without harming readability.

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?

There is no output schema, so the description is the only place an agent could learn what a fetched brand kit returns, and it omits that entirely. For a simple read tool with readOnlyHint coverage the gap is not fatal, but an agent cannot tell whether it will receive assets, colors, fonts, or just metadata.

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%, so the description must carry parameter meaning, and it only weakly does: 'by id' implies brand_id is an identifier but says nothing about expected format (UUID, slug, numeric) or validity constraints. One required parameter is effectively undocumented in both structured and unstructured text.

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 (Fetch) and resource (one brand profile) qualified by 'by id', which cleanly distinguishes it from the sibling list_brand_kits. It loses a point for calling the resource a 'brand profile' while the name and siblings say 'brand kit', a small terminology mismatch an agent must reconcile.

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?

'Fetch one brand profile by id' implicitly signals single-record lookup with a known identifier, so the alternative list_brand_kits is inferable. However, it never states when this tool should be chosen over list_brand_kits, nor how an agent obtains a brand_id in the first place, so guidance is only implied.

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