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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds useful context beyond that: the data source (synced DB) and the output format (JSON, not PDF, referencing the underlying service/endpoint). It does not mention pagination, size, or auth, but with annotations carrying the safety profile a 3 is appropriate.

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 short, front-loaded sentences with no filler. The scope qualifier ("no PDF") and data source come early. It is tight, though it leaves obvious capacity unused given the tool's huge surface.

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 described. However, for a tool with 33 undocumented, all-optional parameters, the description is far too thin to make the tool callable with confidence. It does not compensate for the total absence of parameter documentation.

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?

There are 33 parameters at 0% schema description coverage, and the description explains none of them. The parameter set even contains mutation-flavored fields (confirm, dry_run, confirm_live, action, reason) that are completely unaddressed, leaving the agent unable to know what any argument means.

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 states a specific verb+resource ("Build a Kampalo performance report JSON") and adds scope detail ("from synced DB (no PDF)"). An agent knows this returns JSON rather than a PDF and pulls from synced data. However, it does not distinguish itself from the many other automate_* and analytics_* siblings.

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 alternative. The "no PDF" note hints at scope but does not tell the agent when to choose this over analytics_get_* or other report tools. Usage must be fully inferred.

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