Verify ownership and inspect public identity evidence

hubvibe_identity_check

Read-onlyIdempotent

Non-government identity intelligence: email/DNS/wallet challenge proofs, GitHub and Bluesky public profiles, GLEIF/SEC business records, signed A2A cards and the canonical Base ERC-8004 registry. Separates ownership from public-record matches and unverified claims, with evidence, timestamps and fraud indicators. Required evidence failures refuse delivery. Existing contact screening remains available. No documents or biometrics. $3.00 per call. Returns: verification_status, verified (scoped ownership only), ownership[], findings[], profiles[], businesses[], agent, screening, correlations[], fraud_indicators[], sources[], checked_at, limitations[].

B3.3/5.0

Behavior4/5

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

Annotations already declare readOnly/idempotent/openWorld and non-destructive, so the safety profile is covered. The description adds genuinely non-derivable behavior: a $3.00 per-call cost, that failing required evidence refuses delivery, that 'verified' is scoped to ownership only, and that public-record matches and unverified claims are separated. It does not mention rate limits or upstream source failure behavior, keeping it out of the top band.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The first sentence is a strong front-loaded scope statement, but the body is a run-on catalogue of sources and the final sentence enumerates every return field, which duplicates the output schema. Several clauses (fraud indicators, timestamps, correlations) restate return values rather than helping the agent call the tool.

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?

For a 15-parameter, nested-object, open-world tool the description does cover purpose, cost, refusal semantics and the verified/claims distinction, and the output schema handles returns. Still missing is how the optional inputs compose into a check (e.g. proofs + required_checks + agent), which is the main thing an agent needs to invoke it correctly.

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

Parameters2/5

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

Schema description coverage is only 7% against 15 parameters, including nested objects (agent, business, proofs), so the description must carry the semantic load and largely does not. It names evidence domains (email, DNS, wallet proofs, GitHub/Bluesky, GLEIF/SEC), which loosely maps to email/domain/proofs/platforms/business, but nothing explains required_checks, proofs challenge_id/access_token mechanics, phone/birth_year, or why all params are optional.

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 resource with concrete scope: email/DNS/wallet challenge proofs, GitHub/Bluesky profiles, GLEIF/SEC records and the Base ERC-8004 registry. It is clearly an identity-evidence aggregator rather than a plain email or DNS check. It loses a point because the enumeration is dense and no sibling is named directly, so the boundary against hubvibe_email_verify, hubvibe_domain_dns or hubvibe_company_enrich is only implied.

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?

It gives explicit exclusions ('No documents or biometrics') and a note that 'Existing contact screening remains available', which hints at hubvibe_contact_screen. However, it never states when an agent should pick this over the many overlapping siblings (email_verify, domain_dns, sanctions_screen, company_enrich), so usage is inferable but not routed.

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