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

The description adds several details beyond the annotations: the operation only recommends rather than applies an update, it is deterministic and evidence-bounded, it produces a signed result, and it costs 0.004 USDC. These are genuinely informative and consistent with the readOnlyHint, idempotentHint, and destructiveHint annotations.

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 compact and front-loaded with the core purpose, followed by cost and behavioral guarantees. No sentence is wasted, and all included details earn their place, even though the semicolon before '0.004 USDC' is stylistically awkward.

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?

The description covers high-level behavior, cost, determinism, and signing, and an output schema exists so return format does not need to be explained. However, it lacks input structure details, usage context, and sibling differentiation, leaving an agent under-equipped to confidently construct a valid call among the large sibling set.

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 input schema declares no named properties and allows arbitrary properties, while the description's only semantic pointer is 'verified outcome evidence.' The description does not specify what evidence fields, identifiers, or reputation values are expected, so an agent still lacks concrete input-construction guidance despite the nominal zero-parameter count.

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 clearly states a specific action ('Recommend'), a specific resource ('a bounded auditable reputation update'), and a source ('verified outcome evidence'). It reads as a distinct advisory tool rather than an execution or evidence-gathering tool, though it does not explicitly contrast with sibling tools like agent_reputation_evidence or erc8004_reputation_intelligence.

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 'from verified outcome evidence' implies the intended context: use when verified evidence exists and a reputation adjustment is being proposed. However, the description does not state when not to use it, what prerequisites must hold, or how it differs from the many reputation and evidence-related sibling tools.

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