A4.1/5.0
Behavior4/5

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

Annotations only declare readOnlyHint and openWorldHint; the description adds substantive context beyond them: no browser required, missing facts return null, and a disclosed price of $0.002 per result. It omits failure modes (non-product URLs, blocked pages, rate limits), which keeps it below a 5.

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

Conciseness4/5

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

Two dense sentences, front-loaded with the resource and output shape, then pricing and routing. The telegraphic semicolon-run style is efficient but slightly compressed, and the trailing sibling names read as a tag list rather than integrated guidance.

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?

With an output schema present, the description needn't explain return values, and it correctly focuses on sources, null handling, and cost. What is missing is behavior on unsuccessful extraction, which matters for an open-world scraping tool.

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?

Schema coverage is 100%, so both parameters are already documented in the schema, including the 'product page rather than store homepage' constraint. The description adds no syntax, format, or constraint detail beyond that baseline.

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?

States a specific verb and resource (product page → JSON) and enumerates the extracted fields (price, stock, variants, ratings, shipping) plus the extraction sources (JSON-LD, Microdata, OpenGraph). An agent can distinguish it from siblings like url_to_clean_markdown without opening either schema.

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?

Explicitly routes two adjacent use cases to named siblings: cross-store schema comparison to agentic_shelf_schema_comparator and store audits to muse_agentic_store_readiness_auditor. It does not state exclusions for the more obvious alternative (url_to_clean_markdown) or what to do when the page is not a product page, so the guidance is clear but incomplete.

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