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

Annotations declare readOnlyHint=true and openWorldHint=true, so the safety profile is already covered. The description adds that input is a pre-existing dataset ID and that the actor consumes third-party scraper output, but says nothing about runtime, cost, or what happens on an invalid dataset ID.

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 first sentence is duplicated verbatim and truncated ('ready….') before the full version appears, wasting the front-loaded position on broken text. The remaining content is short, but the redundant fragment is a structural defect, not conciseness.

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?

With no output schema and an opaque input schema, the description must carry the full burden. It names the two outputs but omits the shape of the score output, the dataset requirements, and any actor-invocation specifics an agent would need to call it correctly.

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 coverage is nominally 100%, but the only schema help is a URL pointer, so the description's 'Paste a dataset ID' carries the real semantic load for the single nested 'input' object. It does not document the nested fields inside that object, so it only partially compensates.

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?

States a specific transformation: Google Maps or LinkedIn scraper output into 0-100 intent scores plus email hooks, which is more than a restatement of the name. It does not distinguish itself from nearby siblings like signal_radar or b2b_hiring_signal_tracker, so sibling differentiation is missing.

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?

'Paste a dataset ID' and 'Works with any lead scraper output' imply the usage pattern: run this after a scraper produces a dataset. There is no explicit when-not guidance, no prerequisite checks, and no named alternative for agents that only need scoring vs. enrichment.

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