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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered by structured data. Beyond that the description adds only the semantic distinction between the two bot categories; it says nothing about the time window defaults (days vs from/to), pagination, or what a 'report' row contains. With annotation coverage this is an acceptable but thin contribution.

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, densely packed, with the core purpose front-loaded before the kind taxonomy. No filler, though the hyphenated phrasing is slightly telegraphic and reads more like a fragment than a complete instruction.

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 seven parameters including a nested filter object, the agent still cannot tell what the report returns (per-bot rows? aggregates? which fields?) or how the window is determined when only site is supplied. For a parameterized reporting tool with a nested filter object, the description leaves substantial operational questions unanswered.

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 43% across 7 parameters including a nested filters object, so the description needs to compensate and largely does not. It adds real meaning for 'kind' (catalog bots vs behavioral threats, beyond the bare enum), but leaves site, to, days, and the ambiguous relationship between days and from/to entirely unaddressed in prose.

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 resource ('bot traffic on a site') and explains the human-vs-bot split DevDome performs, which lets an agent distinguish this from analytics tools like get_stats or get_breakdown. It never states a retrieval verb explicitly, but the resource scope is clear enough to identify the tool.

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 sentence 'kind bots = known-bot catalog activity; threats = suspicious/behavioral detections' effectively tells the agent which mode to choose for which question, which is genuine usage guidance. However, there is no guidance on when to call this versus get_stats, get_breakdown, get_visitors, or lookup_bot, and no exclusions or prerequisites.

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