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

With no annotations, the description carries the full burden. It does disclose the important behavioral facts that this is a paid call ($0.05 USDC on Base) and that it bundles many analyses, which is genuinely useful. However, it does not explain the payment gating behavior — that omitting paymentSignature likely yields a payment challenge, or whether an unsigned call runs at all — nor any latency, rate limit, or side-effect profile.

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 verb and resource are front-loaded, which is good, but the remainder is a single dense marketing sentence packed with branded jargon ('Brand Sanitizer', 'Phantom Lead Shield') that an agent cannot act on. Some listed components double as a useful output preview, so the length is not pure waste, but it is closer to a sales pitch than a specification.

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?

There is no output schema, so the description must convey what comes back; the component list does serve as a rough return-value preview (contacts, SEO audit, scripts), which partially covers that gap. What is missing is the payment flow contract and any indication of output format or size for a tool that claims to produce a full dossier.

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 100%, so the four parameters are already documented, and the baseline is 3. The description adds marginal value only by tying the stated $0.05 USDC price to the paymentSignature parameter; it says nothing about how url, businessName, or agencyOffer shape the output beyond what the schema already states.

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 names a specific verb and artifact ('Generate a complete B2B SDR Outreach Dossier in 1 call') and enumerates the bundled components, so an agent knows this is an all-in-one bundle rather than a single narrowly scoped analysis. It implicitly distinguishes itself from narrower siblings like audit_technical_seo or enrich_business_lead by the 'in 1 call' framing, but never names those siblings explicitly.

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 'in 1 call' phrasing implies the usage case (choose this instead of chaining several focused tools), which is useful but never stated as an explicit rule. There is no guidance on preconditions, such as what happens when the target URL is not a real business site or when the payment signature is omitted.

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