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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds the useful fact that each form is returned with active state, impressions and conversions, but says nothing about pagination behavior, result ordering, or rate limits.

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 sentences with no filler, and the data fields an agent cares about are front-loaded. The raw endpoint path is arguably redundant with tool metadata but is compact enough not to hurt.

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 simple, fully-annotated list tool with a 100%-documented schema, the main missing element is any statement of what the response looks like in aggregate (total counts, paging metadata) since no output schema exists. The brief field list partially compensates but leaves the return shape underspecified.

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?

All three parameters (q, limit, offset) are fully documented in the schema at 100% coverage, including the next_offset paging hint, so the baseline is 3. The description adds no filtering or paging semantics beyond what the schema already provides.

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 the resource and the notable data it carries ('Lead capture forms with active state, impressions and conversions') plus the REST endpoint, so an agent can infer a read/list operation. However, it never states the operation with a verb — the listing behavior comes from the name and GET path, not the text, and nothing separates it from sibling list_* tools beyond the resource noun.

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 guidance about when to use this tool, when not to, or which sibling to pick; the agent must infer from the resource name alone. Prerequisites such as needing an accountId are only visible via the endpoint string, not spelled out.

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