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

Annotations already establish readOnly, idempotent, non-destructive behavior, so the bar is lower. The description adds real output context beyond annotations: the returned `url` earns the creator commission, and `storyImageUrl` is a 1080x1920 JPEG ready to post as a story.

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?

Three tight sentences with zero filler. It front-loads what the tool returns, then the actionable instruction (deliver the url), then a note on the image asset, each earning its place.

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, the description carries the burden of explaining returns and does so: the url, the commission mechanic, and storyImageUrl format. It is nearly complete, only lacking any note on error cases or what happens if the tralha slug is invalid.

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 100%, so both parameters (handle as the creator's @ on iscabox, tralha as the slug from get_creator_page) are already documented in the schema. The description adds no syntax or format detail beyond that, so the baseline 3 is appropriate.

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?

States a specific verb+resource: retrieves a creator's 'tralha' (the gear kit used in a video), and details what it contains (each item's version and today's lowest price). This distinguishes it from generic equipment searches, though it does not explicitly contrast with the sibling build_tralha.

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?

Usage is implied through chaining: the tralha param is noted as coming from get_creator_page, and the description instructs delivering the `url` to the user. However, there is no explicit when-to-use/when-not guidance or direct comparison against alternatives like build_tralha or get_equipment_details.

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