netintel_url_safety_full

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

With no annotations, the description carries the full disclosure burden. It usefully reveals two non-obvious behaviors absent from any structured field: the sub-checks run concurrently, and partial results are returned gracefully on failure. It says nothing about rate limits, cost, auth requirements, timeout behavior, or what an invalid/unreachable URL yields.

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 core capabilities are front-loaded in a single dense clause, which is good, but the sentence is truncated mid-thought ('...so agents get…'), leaving a dangling benefit clause and an incomplete description. Size is appropriate; the cut-off ending is a real defect.

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?

This is an aggregator that fuses four sub-tools, yet there is no output schema and no description of the combined result shape — the single dangling clause ('so agents get…') was the only place return value was addressed, and it is incomplete. For a tool of this breadth with zero annotation and zero output-schema support, the description leaves the agent unsure what it will actually receive.

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?

One parameter ('url') with 0% schema description coverage and no annotation help. The description only implies the input is a URL, adding nothing the schema does not already convey — no format expectations (scheme required? bare domain accepted?), no normalization or length limits. With low coverage, the description was expected to compensate and does not.

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?

Uses a specific verb ('vets') with a named resource ('a URL') and enumerates exactly what the vetting covers: redirect chain, malware/phishing databases, security headers, SSL certificate. It does not, however, reference the sibling netintel_url_safety (the presumably lighter variant) or any other sibling that performs these sub-checks individually, so the agent must infer the distinction from the 'full' suffix alone.

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?

'One call ... end to end' implies the use case (comprehensive URL vetting in a single call), but there is no explicit when-to-use/when-not guidance and no routing against netintel_url_safety, netintel_redirect_trace, netintel_security_headers, or netintel_ssl_analyze, which overlap heavily with this tool's scope. The agent can infer intent but not the selection criteria.

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