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

Annotations already declare readOnly/idempotent/non-destructive, and the description adds genuinely new behavioral facts: nothing is opened or executed server-side, the return value is guidance, and the Sleeper API is limited. The only weakness is that the "checked 28 Oct 2026" note is a dangling fragment that adds little.

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?

The key facts (returns steps, opens nothing, use cotlet_browser_*) are front-loaded and short overall, but the final sentence is a fragment that trails off without a predicate and the submit-vs-guide ambiguity costs clarity.

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?

With no inputs and no output schema, the description covers what an agent needs: what comes back (screens, buttons, fields) and what to do next. It could say more about whether the returned steps are account-specific, but nothing critical is missing.

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?

Zero parameters and 100% schema coverage, so there is nothing for the description to disambiguate. Baseline for a parameterless tool applies.

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 name and title say "submit waiver claim," but the description reveals the tool actually returns step-by-step instructions and "opens nothing by itself." The resource (waiver claim in the user's Sleeper account) is specific, but the verb in the name is in tension with the described behavior, so an agent could plausibly expect a real submission.

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?

It gives a clear two-step workflow: call this to get screens/buttons/fields, then perform the action with the cotlet_browser_* tools. It does not state when not to use it or how it differs from the other sleeper_* action siblings, but the context is unambiguous enough to route correctly.

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