Request a crawl

request_crawl

Enqueue one or more packages for crawling without waiting for results, pre-warming data before comparing alternatives.

Instructions

Enqueue one or more packages for crawling without waiting for the result. Useful for pre-warming several packages at once, e.g. before comparing alternatives.

Behavior3/5

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

No annotations are present, so the description carries the burden. It discloses that the operation is non-blocking ('without waiting for the result') and that it enqueues, but it does not clarify return behavior, authentication needs, or queue side effects, leaving some ambiguity.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences, front-loaded with the core action, and every clause contributes value. No wasted words or repetition of schema fields.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple tool with 2 parameters and no output schema, the description covers the main behavior and a use case. It lacks explicit mention of what the caller receives after enqueueing, but given the tool's low complexity, it is reasonably complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema already provides 100% coverage of both parameters with descriptions, so the description adds little beyond reinforcing that multiple packages can be submitted ('one or more'). It does not introduce new constraints or format details beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Enqueue' and the resource 'packages for crawling,' and distinguishes itself from siblings by emphasizing 'without waiting for the result,' which contrasts with synchronous retrieval tools like get_package.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It provides a clear use case: 'pre-warming several packages at once, e.g. before comparing alternatives,' which implies when this tool is appropriate. However, it does not explicitly name alternatives or state when not to use it, so it falls short of a full 5.

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