Fabrica (Sepolia testnet)

Explain confidence score

explain_confidence_score
Read-onlyIdempotent

Explain a Fabrica property's confidence score breakdown. The score is a 5-digit positional number where each digit represents a different verification category: recovery status (ten-thousands), past title (thousands), ownership (hundreds), onchain history (tens), basic validation (ones). Max score: 75342.

TDQS

A3.5/5.0
Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint, so the safety profile is covered. The description adds genuinely non-obvious domain behavior: how the score is encoded and what each digit position means. It does not address auth, rate limits, or whether tokenId performs a lookup with side effects, but with annotations carrying the safety burden this is strong added context.

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?

Two sentences, front-loaded with the purpose before the digit mapping. The digit-position breakdown is information-dense but each clause is necessary and there is no filler.

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?

No output schema exists, so the description must convey the return semantics; it partially does by explaining the digit breakdown. However, with two optional and zero required parameters, it never clarifies when to supply 'score' versus 'tokenId' or what happens if both/neither are provided, leaving a real gap for an agent deciding how to call it.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline would be 3. The description goes beyond the schema by explaining the meaning of the score integer (5-digit positional encoding, category per digit, max 75342), which materially helps interpret the 'score' parameter. It adds nothing about how tokenId resolution works or how the two optional params interact.

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?

States a specific verb and resource: it explains a property's confidence score breakdown. This is clearly distinct from the get_* siblings, which retrieve entities rather than interpret a score. It stops short of naming any alternative or contrasting scope, so it is clear but not maximally differentiated.

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?

There is no explicit when-to-use or when-not-to-use guidance, and no routing to alternatives. The reader must infer that this tool is for interpreting a score integer or a token's score. Nothing states prerequisites or the relationship between the two optional inputs.

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