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

With zero annotations, the description carries the full disclosure burden. It does add genuinely useful context beyond structured fields: calls use the caller's OpenAny gateway credentials, and charges/authorization are decided by the gateway. It says nothing about pagination behavior, what happens on an unknown domain, or result freshness, and read-only status is only implicit in 'Returns'.

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?

Two sentences, front-loaded with the return value, with no filler. The second sentence is a useful operational note rather than padding, though the definition is short enough that there is room to say more without bloat.

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 7-parameter tool with no output schema and no annotations, this is thin. The title promises 'with evidence' but the description never explains what a 'Technology Detection' contains (technology name, first/last seen, evidence source), so the agent cannot anticipate the response shape. Pagination behavior across page/limit is also unaddressed.

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 86%, so the schema already documents the date filters, the limit default/max, and that company_id_or_domain accepts a domain or a PredictLeads UUID. The description adds nothing about any parameter and does not mention the schema's 'first_seen_at_from = newly adopted technologies' trick, so baseline 3 applies.

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 verb and resource ('Returns Technologies used by a specific Company as a list of Technology Detections'), which is far clearer than the encoded tool name. It does not, however, distinguish itself from sibling technographic sources such as dataforseo domain_technologies, anyapi run_technographics_theirstack, or the other treg_get_call_predictleads_* endpoints, so an agent cannot tell why to pick this one.

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?

There is no when-to-use, when-not-to-use, or alternative-naming guidance. The description only implies usage from the purpose statement, and given the many overlapping tech-stack tools in the sibling list, the absence of routing guidance is a real gap.

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