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

Annotations already declare readOnly, non-destructive, closed-world, so safety is covered. Beyond that, the description adds nothing: no default time window, no note that it fans out over log indexes via the query param, no indication of aggregation granularity or whether results are sampled.

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?

A single short sentence with no filler and the key qualifier ('quick summary') front-loaded. It is tight, though the brevity borders on 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?

An output schema exists so return values need not be explained, and annotations cover safety. But with four all-optional parameters and no stated default time range, an agent calling this with no arguments has no idea what period it summarizes — a material gap the description should close.

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 only 50%: 'to' and 'from' have no descriptions anywhere, and the description says nothing about parameters, so an agent cannot infer whether they are date bounds, entities, or free text. 'query' and 'context_id' are documented in the schema, but the description contributes zero semantic value on top.

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 phrase 'summary of unwanted traffic (bots/WAF)' identifies the resource and the output shape (an aggregate summary), but the verb is nominalized and the source is vaguely 'your logs'. The description never names Datadog (only the title does) and never differentiates itself from sibling log tools like dd_logs_search, dd_logs_aggregate or dd_errors_by_service.

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 word 'Quick' hints at an overview use case, but there is no explicit when-to-use, no when-not-to-use, and no alternative named. With ~20 dd_* siblings, the agent gets no routing guidance at all from the description.

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