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

Annotations already declare readOnlyHint=false, destructiveHint=true, so the safety profile is known; the description adds the API-key requirement and clarifies what each action does to the recommendation (adopt, dismiss, modify). It does not disclose whether a rejection is permanent or reversible, nor whether adaptation creates a new claim or mutates the existing one, which matters for a destructive mutation.

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 tight sentences, front-loaded with the core verb and resource, followed by the action vocabulary and the auth requirement. No filler or redundancy.

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 destructive 5-parameter mutation with no output schema, the description covers actions and auth but omits how to obtain the required id, what a successful call returns or changes, and whether reject/adapt are undoable. Adequate but with clear gaps given the tool's complexity.

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%, so the schema already documents id, notes, action, adapted_why, and adapted_rule. The description reinforces the action enum semantics but does not mention that adapted_rule is required when action is 'adapt', leaving that conditional dependency to the schema description.

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 a specific verb (review) and resource (a recommendation from your inbox) and enumerates the three possible outcomes: accept as-is, reject to dismiss, adapt to modify. It does not explicitly differentiate itself from read-side siblings like get_inbox or get_inbox_stats, so an agent must infer that this is the write-side counterpart to those listing tools.

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?

Usage context is implied (act on a recommendation surfaced in the inbox) and the three action semantics are spelled out, which helps the agent pick the right action value. However, there is no guidance on prerequisites — an agent is not told it must first obtain an id via get_inbox — and no when-not-to-use guidance versus approving or declining coaching actions.

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