TDQS

B3.2/5.0
Behavior3/5

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

The annotations already declare this a read-only, idempotent, non-destructive open-world call, so the safety profile is covered. The description adds a published per-request price ($0.008/request), which is useful cost context, but nothing about rate limits, symbol ambiguity, or response behavior beyond what the schema already states.

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?

The purpose statement is one front-loaded sentence with no wasted words. The appended pricing block is boilerplate but informative and clearly delineated.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists and annotations cover safety, so the remaining gap is guidance for a 10-parameter tool: which lookup key to choose and how this differs from sibling price endpoints. For a moderately complex endpoint the description is adequate but leaves the agent to infer selection.

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 description coverage is 100%, so every parameter is already documented in the schema, including the enum choices for precision and include_tokens. The description adds no extra meaning about how ids, symbols, and names interact or about the one-required-parameter constraint.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description has a specific verb (query prices) and resource (coins), and it names the three lookup keys (IDs, symbols, names), which matches the schema. It does not, however, distinguish this tool from close siblings such as get_coingecko_simple_token_price_id or get_coingecko_coins_id.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It says nothing about when to use this tool versus the many other price and coin endpoints in the sibling list, and it gives no exclusions or prerequisites. The intended usage (get a lightweight price quote) is only inferred from the word 'price'.

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