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

Annotations already declare readOnlyHint=false and idempotentHint=false, so the write nature is covered; the description adds real value by disclosing the downstream consequence — the order gets billed and shipped again — plus the underlying endpoint. It stops short of stating permission requirements, failure modes (e.g., no skipped order exists), or that a repeat call restores the next-earliest skip.

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 sentences, both earning their place: the 'WRITE:' prefix front-loads the mutation risk, the consequence follows, and the parameter note and endpoint are packed into the tail without padding.

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 3-parameter mutation with no output schema, the description covers intent, effect, parameter default, and endpoint — enough to call it correctly. Missing only error/precondition behavior (what happens if no skip exists) to be fully self-sufficient.

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 all three parameters are already documented. The description's note about `date` restates the schema default rather than adding format examples or behavior for a date that isn't skipped, so the baseline 3 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?

States a specific verb (restore) on a specific resource (a previously skipped order of a subscription) and immediately names the business effect: it will be billed and shipped again. The inverse relationship to the sibling smartrr_skip_order is obvious, so an agent can route correctly without opening the schema.

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 makes the effect clear (restores billing/shipping) and notes the default when `date` is omitted, which implies the selection rule. However it never explicitly says when to use this versus siblings (skip_order, set_next_billing_date, resume_subscription) or what precondition must hold (an order must actually be skipped).

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