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, yet it discloses nothing: not whether scoring is deterministic, what inputs feed it, permissions required, or what a risk score represents. The spec code 'DFI-101-RiskScoreBound' hints at bounds but is unexplained.

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?

Extremely short, but this is under-specification rather than conciseness — there is essentially no content to front-load. The only non-name token is an internal spec identifier.

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 tool requiring three parameters, including two nested objects with zero documentation, no output schema, and no annotations, the description is completely inadequate. An agent cannot call this correctly without external knowledge of the DFI-101 spec.

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% across three required parameters, two of which are untyped nested objects (position, market_conditions). The description adds no field-level meaning, so an agent has no idea what shape to supply for the object parameters.

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 'DeFi risk scoring' essentially restates the tool name (defi_risk_score) rather than specifying what is scored or how. The parenthetical 'DFI-101-RiskScoreBound' is an opaque spec identifier that conveys no meaning to an agent. It does not differentiate from siblings such as defi_contract_audit, defi_liquidation_check, or threat_score.

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 the many other defi_* risk-adjacent siblings (defi_contract_audit, defi_liquidation_check, defi_oracle_verify). No prerequisites, no exclusions, no alternatives named.

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