update_kit

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

No annotations exist, so the description fully details behavioral traits: how to pass CDN URLs from upload functions, how to remove images by setting empty strings, and how to reset Pro+ meta fields with null.

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 tightly packed sentences with no redundancy; front-loaded purpose followed by essential parameter usage notes.

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?

Given 11 parameters with nuanced behaviors (Pro+ restrictions, null vs empty string), no output schema, the description provides sufficient context for correct invocation.

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 100%, but the description adds critical context beyond schema, like sourcing CDN URLs from upload_file/upload_asset and the distinction between empty string removal and null reset for Pro+ fields.

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 clearly states 'Update a kit's top-level settings' and lists specific fields (name, accent color, template, etc.), distinguishing it from sibling tools like create_kit and get_kit.

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?

The description implicitly indicates usage for updating existing kit settings, but does not explicitly contrast with sibling tools for block-level changes or provide when-not-to-use guidance.

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