gate_get_price

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

No annotations provided, so description carries full burden. It fully discloses non-monetary nature ('costs nothing and never moves money'), behavior when URL not paywalled ('the tool says so instead of returning a price'), and preview functionality without side effects.

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?

Three concise sentences, each providing essential information: first states purpose and outputs, second provides usage guidance, third confirms no cost. No redundant words.

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 simple tool (1 parameter, no output schema, no nested objects), description is fully complete: covers purpose, inputs, return info, edge case, and usage context. No gaps.

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 has 100% description coverage for the single 'url' parameter. The description adds context: specifies absolute https URL, gives example ('https://example.com/api/report'), and explains edge case behavior if not paywalled, exceeding schema info.

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 uses specific verb 'Preview' and resource 'Solinkify Gate paywall', detailing price, currency, and access modes. It distinguishes itself from sibling tool 'gate_fetch' by stating 'Call this before gate_fetch to learn the price' and clarifies it costs nothing and never moves money.

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?

Clearly states when to use ('Call this before gate_fetch'), what it does not do (cost nothing, never moves money), and provides safety guarantee. Explicitly tells the agent to use this to learn price before gate_fetch.

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