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

The annotations already declare readOnlyHint=true and openWorldHint=true, so an agent knows the operation is a safe read against an open API. The description adds genuinely new behavior: the call deducts from a quota ('Kotadan düşer'), which is important cost information not present in the annotations. It omits error behavior and rate-limit details, so it stops short of 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.

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

Three short sentences: the capability first, then the sourcing rule, then the placeholder behavior, and finally the quota warning. Nothing is padded, and each sentence carries actionable information.

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?

For a two-parameter passthrough tool with no output schema, the definition covers purpose, sourcing, placeholder resolution, and quota cost. It does not describe the shape of the returned payload or what happens on a failed call, but no output schema exists to make that redundant, so a small gap remains.

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%, so both parameters are already documented. The description still adds meaning beyond the schema: it explains that `{ad}` placeholders in the path can be filled either through `parametreler` or inline in the path itself, which is a real usage rule not stated in the schema.

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?

Description states a specific verb and scope: it calls any GET /v1 endpoint. It also distinguishes itself from the sibling `uc_ara`, which is the discovery tool that supplies the path and parameters; this is the execution tool.

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?

It gives an explicit workflow: obtain the path and parameters from `uc_ara`, then invoke here. It also limits scope to GET endpoints, implicitly excluding write methods. It does not name a condition under which another tool should be preferred instead, but the routing to `uc_ara` covers the main ambiguity.

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