Uploadkit

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively describes key behavioral traits: the return format (JSON with specific fields), sorting behavior ('Pages are sorted alphabetically by path'), and operational characteristics ('Read-only, static at bundle time, idempotent'). This covers safety, data freshness, and idempotency well.

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?

The description is efficiently structured in three focused sentences: purpose statement, usage guidelines, and behavioral details. Every sentence adds essential information with zero wasted words, and key information is front-loaded appropriately.

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 the tool's simplicity (0 parameters, no output schema, no annotations), the description provides complete context. It explains what the tool does, when to use it, what it returns, and key behavioral characteristics. No additional information is needed for effective use.

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?

The tool has 0 parameters with 100% schema description coverage, so the baseline would be 4. The description correctly indicates no parameters are needed ('Enumerate every available...' implies no filtering parameters), which aligns perfectly with the empty input schema.

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 the specific action ('Enumerate every available UploadKit docs page') and resources involved ('with title, description, URL, and path'). It distinguishes this tool from its sibling 'search_docs' by explaining this is for discovery while search_docs is for targeted queries.

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 explicitly provides when to use this tool ('to discover what documentation exists before targeted searching, or to orient yourself around the shape of the docs site') and when to use an alternative ('Prefer search_docs when you already have a concrete question'). This gives clear guidance on tool selection.

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