Shareable risk-signals card for a site (SVG) ($0.01/call)

verdict_card

$0.01 per call (x402, USDC on Base; not covered by the free trial). [SEO, security and site verdicts] The site-verdict risk signals rendered as a branded 1200x630 SVG card: risk level (low observed risk / elevated / high / unknown), risk score 0-100, a one-line summary and the top signals, with a permanent public URL (card_url) to share or embed, plus the inline SVG, signals with evidence and coverage (trust/2). The card says "signals only, not a safety certification" and never shows a safe or legit seal. Text comes from Lordevo's own local model (no cloud AI) blended with rules.

TDQS

A3.7/5.0

Behavior4/5

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

Beyond the annotations, it discloses cost ($0.01/call, x402/USDC, excluded from free trial), that a persistent public artifact is created (explaining why readOnlyHint and idempotentHint are false), and that content is model+rules generated locally. It also discloses the built-in disclaimer and the deliberate absence of a 'safe' seal, which is meaningful behavioral context; what it does not cover is repeat-call behavior (duplicate cards) or rate limits.

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 price and the core purpose are front-loaded, then output contents, then caveats — a sensible order. It is dense and mostly earns its words, but the bracketed tag '[SEO, security and site verdicts]' and the opaque phrase 'coverage (trust/2)' add noise without meaning.

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

Completeness4/5

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

For a one-parameter tool with an output schema, this description covers the important agent-facing gaps: cost, side effects, shareable artifact, interpretive caveats and a methodology link. The remaining shortfall is the lack of explicit routing versus the sibling verdict/report tools.

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?

The schema has a single required parameter with 100% description coverage, so the schema already defines the url input completely. The description adds no syntax, normalization or error-handling detail for the URL beyond what the schema says, so the baseline of 3 applies.

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 states a specific verb and artifact: site-verdict risk signals rendered as a branded 1200x630 SVG card, with risk level, score 0-100, summary and top signals. It is clearly the presentation-layer counterpart of sibling verdict tools, though it never names site_verdict or site_report explicitly, so sibling differentiation is inferential rather than stated.

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

Usage Guidelines3/5

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

The sharing/embedding use case is implied by 'permanent public URL (card_url) to share or embed', and the pricing note warns that it is not free. There is no explicit when-to-use statement contrasting it with site_verdict (raw signals) or site_report, and no guidance on when the SVG card is preferable to a JSON verdict.

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