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

With no annotations, the description carries the full behavioral burden. It does communicate two real traits — the operation is a read, and output is 'Zero-PII' / privacy-scrubbed under a named protocol — which is genuine value. But it says nothing about return shape, aggregation level, rate limits, or what 'bounded' actually bounds, so the mutation-vs-read safety profile is only partially covered.

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?

It is a single front-loaded sentence with no filler or repetition, which is structurally sound. However, the density comes from unexplained jargon rather than information, so it is compact without being informative.

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?

No output schema and no annotations mean the description must explain what a returned 'telemetry summary' looks like and what the four listed surfaces contribute; it does neither. For a forensics query tool, an agent gets no sense of result granularity, units, or what a default (no window_hours) invocation returns.

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?

Only one parameter exists and schema coverage is 100%, with the schema itself documenting the 1–168 hour range. The description never mentions the lookback window, though 'bounded' gestures at it weakly; baseline 3 applies since the schema does the explanatory work.

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 verb ('Reads') and a resource ('bounded Zero-PII Protocol AO-063 telemetry summary'), but the resource is defined entirely in invented jargon and opaque domain phrases ('smartwatch wrappers, homework extensions, exam crops, whispered-ASR classrooms'). An agent cannot tell from this what data actually comes back, nor how it differs from siblings like query_longitudinal_rollups or query_shadow_ai_macro_index, so it amounts to little more than a restatement of the tool name in decorative language.

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 prerequisites, and no named alternatives among a large sibling set of other `query_*` observatories. The word 'bounded' implies some scoping constraint but never states it, leaving the agent to guess whether this tool is the right entry point for a K-12 forensics question.

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