Fetch Apify docs

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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, so the safety profile is clear. The description adds that it fetches 'full content', which is consistent but does not disclose any additional behavioral traits (e.g., rate limits, auth). Since annotations carry the burden, a score of 3 is appropriate.

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 concise, with two main sentences plus a usage section and examples. It is well-structured and front-loaded, containing no unnecessary words. Every part earns 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?

Given the tool has a single parameter, an output schema (so return values are documented), and good annotations, the description is adequately complete. It explains when to use and provides examples. A slight improvement could be mentioning expected behavior for invalid URLs, but not required.

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 input schema has one parameter 'url' with a description, and schema description coverage is 100%. The tool description does not add additional semantic meaning beyond what the schema already provides, meeting the baseline of 3.

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 tool fetches the full content of an Apify or Crawlee documentation page by URL. The verb 'fetch' combined with the specific resource 'docs page' provides a clear purpose, and it distinguishes from sibling tool 'search-apify-docs' which searches rather than fetches.

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 says to use this after finding a relevant page with 'search-apify-docs', providing context for when to use. It also includes usage examples. However, it does not explicitly state when not to use the tool, which would be helpful.

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