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

No annotations are provided, so the description carries the full behavioral burden. It discloses that the call is free ('No charge'), which is useful, but says nothing about read-only behavior, idempotency, return format, or whether any side effects exist.

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 two short sentences and front-loads the core idea. However, 'Free' and 'No charge' are redundant, and the brevity comes at the cost of missing important details.

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?

With no output schema, the description should explain what the tool returns, such as a list of tools and their fixed prices. It does not, nor does it clarify how this differs from fikra_get_tool_catalog, leaving the agent with insufficient context to select it confidently.

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?

The tool has zero parameters, so there is no parameter semantics to document. The baseline score of 4 applies because the schema is empty and the description does not need to compensate for missing parameter details.

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 says it performs 'price discovery for fixed-price tools,' which hints at returning prices, but 'price discovery' is vague and it never states the output or scope. It does not distinguish this tool from siblings like fikra_get_tool_catalog or fikra_estimate_inference_cost.

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?

There is no guidance on when to use this tool versus alternatives such as fikra_get_tool_catalog, fikra_get_balance, or fikra_estimate_inference_cost. The only implied usage is 'when you want prices,' which is not explicit.

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