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

Annotations already declare readOnlyHint, idempotentHint and non-destructive, so safety is covered. The description adds real value beyond that with the default status (pending) and a declared 'Read tier', but it says nothing about pagination despite a limit parameter or about result shape/ordering.

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?

One dense sentence that front-loads the verb+resource and the endpoint before the scope defaults. It is efficient, though 'ai_suggestions' and 'Read tier' are terse internal jargon that cost a little readability.

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?

For a read-only list tool with no output schema and zero schema coverage, the description supplies what an agent needs to call it: default scope, valid status values, and optional project filter. The only meaningful gap is the undocumented limit and no hint about result volume or ordering.

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 0%, so the description must compensate, and it does for two of three parameters: status gets an explicit value list and project_id is flagged optional. The limit parameter is never mentioned, leaving one undocumented input.

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?

States a specific verb and resource (List AI Insights, GET /insights) and defines the resource in domain terms (the audit engine's suggestions for your org, ai_suggestions), which no sibling name alone conveys. The org-level scope plus optional project_id separates it from project-scoped siblings like tascan_project_insights.

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?

Gives concrete usage context: results are pending by default, and the status filter accepts applied, dismissed, explained, expired or all. It never explicitly names an alternative (e.g. resolve_insight for acting on a result, project_insights for project scope), so routing is left to inference.

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