scrape_multiple_webpages

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

No annotations are provided, so the description carries the full burden. It mentions concurrency and speed but lacks critical behavioral details such as rate limits, error handling (e.g., if some URLs fail), authentication needs, or what 'processed concurrently' entails (e.g., thread count, timeouts). For a tool with potential complexity and no annotation coverage, this is a significant gap.

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 appropriately sized and front-loaded: the first sentence states the core purpose, and the following sentences add useful context about concurrency and speed. Every sentence earns its place with no wasted words, making it easy to scan and understand quickly.

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 complexity (concurrent web scraping with configurable methods), no annotations, 0% schema description coverage, but an output schema exists, the description is incomplete. It covers the high-level purpose and benefit but misses details on parameters, behavioral traits, and error handling. The output schema reduces the need to explain return values, but other gaps remain significant.

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 0%, so the description must compensate for undocumented parameters. It mentions 'URLs' but doesn't explain the 'extract_config' or 'method' parameters beyond what the schema provides (e.g., what 'auto' means, how configuration works). With 1 parameter (a nested object with 3 sub-parameters) and no schema descriptions, the description adds minimal value over the bare 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 tool's purpose: 'Scrape multiple webpages concurrently.' It specifies the verb (scrape) and resource (multiple webpages) with the key feature of concurrency. However, it doesn't explicitly differentiate from sibling tools like 'scrape_webpage' (singular) or 'scrape_with_stealth' (stealth-focused), missing full sibling differentiation.

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 implies usage context by stating it's 'much faster than scraping them one by one,' suggesting it should be used for batch scraping. However, it doesn't provide explicit guidance on when to use this tool versus alternatives like 'scrape_webpage' for single URLs or 'scrape_with_stealth' for stealth needs, nor does it mention any exclusions or prerequisites.

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