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

No annotations are present, so the description carries the behavioral burden, and it does disclose one non-obvious behavior: sensor Active state is project-wide even when domain filtering affects traffic totals. It stops short of explaining 'accepted-measurement Active' semantics or any freshness guarantees, but for a zero-argument get operation the core behavioral profile is reasonably clear.

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 description is two focused sentences with the main resource front-loaded in the first sentence and an important scoping caveat in the second. The phrase 'configuration-backed accepted-measurement Active state' is dense, but no sentence is wasted.

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, the description usefully enumerates the main return components: totals, bot/AI-referral subsets, and sensor Active state. It also clarifies the project-wide scope of sensor state. It omits output format and time-window details, but for a parameterless read-only tool it is largely sufficient.

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?

The input schema has zero parameters, so there is no parameter-documentation burden and the baseline is 4. The description alludes to domain filtering, but that filtering is not exposed as a parameter and therefore does not create a schema/description mismatch.

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 verb ('Get with a current resource') and spells out exactly what is returned: website traffic totals, LLM bot and AI-referral subsets, and per-sensor Active state for six named measurement sources. This level of detail distinguishes it from sibling tools like devtune_get_traffic_platforms or devtune_get_ai_referrals despite not explicitly naming those alternatives.

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 guidance, no stated alternatives, and no exclusions comparing this tool to its many siblings. The only contextual note is about scope ('Sensor state is project-wide even when domain filters the traffic totals'), but it does not help an agent decide which traffic-related tool to select.

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