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

Annotations already declare the safety profile (readOnlyHint=false, destructiveHint=false, idempotentHint=false, openWorldHint=false). The description adds valuable specifics beyond that: it sets recommendation_dismissed_until to 30 days from today and explicitly does not change the budget amount or spending data.

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 first sentence front-loads the core action, and the remaining sentences add behavioral detail and return format without waste. The Args/Returns structure is appropriate because there is no output schema.

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 one-parameter mutation with no output schema, the description covers the action, exact field changed, duration, side-effect boundaries, parameter constraint, and return shape. Nothing essential is missing for correct invocation.

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 0%, so the description must compensate. It does by specifying that budget_id refers to the caller's own, active budget, adding a meaningful ownership/state constraint beyond the bare integer type in the schema.

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 (snooze/dismiss), resource (spending-recommendation nudge for a budget), and scope (30 days). It also maps to the exact field being set, making it easy to distinguish from other dismiss_* and update_budget 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?

The description explains what the tool does but offers no guidance on when to use it versus alternatives such as dismiss_payment_warning, dismiss_celebrations, or update_budget. There are no exclusions or prerequisites stated beyond the implicit 'caller's own, active' note.

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