terradeed_extract_structured

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

The description discloses the cost of $0.05 per call, which is a behavioral trait beyond the schema. However, it does not mention read-only nature, failure behavior, rate limits, or any side effects. Without annotations, this is only partial transparency.

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 three short sentences, each providing useful information (purpose, cost, schema behavior). No extraneous text.

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?

The description is adequate for a simple extraction tool without an output schema, but it omits details like the optional instructions parameter, what happens on failure, and any URL limitations. Given no annotations, more context would improve completeness.

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% for all three parameters, so the baseline is 3. The description adds minimal meaning beyond the schema: it reinforces that the schema defines the output fields, but this is largely redundant with the schema description.

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 extracts structured JSON data from a URL using a provided schema, which is a specific verb+resource. It distinguishes from siblings like terradeed_scrape_url by emphasizing structured extraction with a schema rather than a general scrape.

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 for structured extraction but does not explicitly compare to alternatives like terradeed_scrape_url or state when to use one over the other. No exclusions or prerequisites are given.

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