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

Annotations already mark it read-only and non-destructive, and the description adds useful behavioral context: it aggregates three named sources, returns an agreement score, and costs $0.50 USDC per call. No annotation contradiction is present.

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?

Two sentences with no filler; the core purpose, return value, sources, and cost are all front-loaded and each sentence adds value.

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 simple read-only tool with no output schema, the description gives a reasonable summary of what is returned (consensus price and agreement score), but it leaves out parameter behavior such as tolerance_pct and fiat, and does not describe the output shape or failure modes. It is adequate but incomplete.

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 description coverage is 0%, so the description must explain the parameters, but it only indirectly clarifies that 'symbol' refers to a crypto asset. It does not explain 'fiat' or the meaning/effect of 'tolerance_pct', which is a significant gap for a paid, consensus-based call.

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 identifies a specific verb ('Verify'), resource ('current crypto asset price'), and method ('multi-source consensus'), and names the independent sources involved. It is clear but does not explicitly differentiate from sibling tools such as get_crypto_correlation_benchmark or get_resolve_price_threshold.

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 phrase 'Verify current crypto asset price' implies when to use the tool: when an attested, consensus-backed price is needed. However, there is no explicit guidance about when not to use it or which alternative sibling tool to choose.

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