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

Annotations already declare readOnlyHint=true and idempotentHint=true, so the safety profile is covered. The description adds that insights are 'active' and span all teams, but does not clarify what 'active' means (unseen? unresolved?), the return shape, or ordering/pagination.

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 compact sentences with the core purpose front-loaded and the filters following. No wasted filler, though there is no structural signposting beyond the single optional clause.

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, zero-required-parameter list tool with a fully documented schema and no output schema, the description covers scope and filtering adequately. The main residual gap is the meaning of 'active' insights and any ordering/limit interaction guidance.

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 description coverage is 100% and all three parameters (tab with enum, limit 1-25, unseen_only) are already documented in the schema. The description merely restates the enum values and the unseen filter, adding no syntax or default details beyond the structured fields.

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 ('Get'), resource ('active insights'), and scope ('for the authenticated user across all their teams'). The 'my/user-scoped' framing implicitly separates it from team-level siblings like get-team-insight-summary-tool, but no sibling is named explicitly.

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 description notes two optional filters (tab category and unseen_only), which implies when those knobs are useful, but it gives no guidance on when to prefer this tool over alternatives such as get-team-insight-summary-tool or get-my-status-tool, and no exclusions.

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