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

Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=true, so the safety profile is known. The description adds useful non-annotation context by stating "Admin only", which is an authorization prerequisite the annotations do not capture. However, it does not explain what is destroyed or replaced when intervals are set, nor why an idempotency key and expected revision are required, so it leaves significant mutation semantics implicit.

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 description is two short, front-loaded sentences with no wasted words. It is not bloated, but its brevity comes at the cost of omitting important mutation details rather than being efficiently comprehensive.

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?

Given a destructive offers-policy mutation with a required expected_revision and idempotency_key and no output schema, the description is too thin. It does not explain optimistic concurrency, whether the supplied offsets replace or append to the existing schedule, or what happens on revision mismatch. Only the admin restriction is added beyond the title and annotations.

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 carry parameter meaning; it only contributes the unit for offsets_seconds by saying the intervals are "in seconds". It says nothing about idempotency_key, expected_revision, request_id, the maximum of three offsets, or that offsets must be positive. For a mutation tool requiring a concurrency token and idempotency key, this is a substantial gap.

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?

Tautological: description restates name/title.

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 only usage guidance is the audience restriction "Admin only"; there is no explicit when-to-use condition, no mention of the read counterpart for inspecting current intervals, and no exclusions. An agent is left to infer that this should be used only when an admin intends to overwrite the reminder policy.

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