merit_list_prices

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

No annotations are provided, so the description must carry the full behavioral burden. It only states 'List' and 'No filters', with no disclosure of return format, pagination, performance characteristics, or authentication requirements. For a tool with zero annotation coverage, this is significantly lacking.

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 a single sentence, front-loaded with the action and resource, and the 'No filters' note is succinct. No wasted words, perfectly concise for a trivial tool.

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 simplicity (no parameters, no output schema, no annotations), the description is minimal but arguably sufficient for an agent to call the tool. However, it does not specify what the response contains (e.g., all price lists, pagination hints) or any constraints, and with siblings present, a bit more context could aid selection. It is adequate but not thorough.

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?

With zero parameters, the baseline is 4. The description adds 'No filters' which reinforces the schema (empty object) but provides no new semantic value since the schema already conveys there are no parameters. The baseline score is appropriate.

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 a specific verb 'List', the resource 'Merit Aktiva sales prices', and the HTTP endpoint. It distinguishes itself from siblings like 'merit_get_price' (singular) and 'merit_send_prices' by specifying it returns a list with no filters, making it unambiguous.

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 says 'No filters' which implies it returns all prices, but it does not explicitly mention when to use this tool over alternatives such as 'merit_get_price' (presumably for a single price) or 'merit_send_prices'. Usage context is implied but not fully articulated.

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