Verify Catalog Register

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

Annotations already declare readOnlyHint=false, openWorldHint=true, destructiveHint=false, so the mutation/safety profile is covered structurally. The description adds genuinely useful context the annotations lack: it is a paid call costing 0.25 USD via x402 on eip155:8453, which materially affects whether an agent invokes it. It still does not say what the verification does, what state changes (if any) the POST causes, or what a failure looks like.

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 — two lines — and the route/payment is front-loaded after the header. But the header sentence is pure restatement of the title and earns nothing, and the brevity here reflects under-specification rather than economy.

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 6-parameter, zero-required, paid, open-world endpoint with 0% schema coverage, the description is far too thin. The output schema relieves it of explaining return values, but it still needs to explain the claim/edges/signature payload shape and the cost/failure implications.

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 six undocumented parameters (claim, edges, signature, service_url, claim_sha256, service_name), and none are required. The description says nothing about any of them, so an agent has no way to know what a 'claim' or 'edges' payload should contain or why both claim and claim_sha256 exist.

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 first line is a verbatim restatement of the tool title ('Verify Catalog Register'), which is tautological. The only substantive content is the routing/payment detail (POST /v1/verify-catalog/register, 0.25 USD x402 on eip155:8453); nothing explains what 'verify' means, what a catalog register is, or how it differs from siblings like `catalogue` or the `v1_verdict_*` family.

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?

No when-to-use, when-not-to-use, or alternative routing is given despite this tool sitting among ~100 siblings including `v1_bio_catalogue`, `v1_verdict_service`, and `catalogue`. The agent must infer usage entirely from the name.

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