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

With no annotations supplied, the description carries the full burden and does disclose the key behavior: an outbound customer email is triggered, sent from the shop, with replies going to the shop owner. That is the critical consequence an agent needs to know before invoking. It omits idempotency, whether the recap must be in a drafted state, and irreversibility, so it is not exhaustive.

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?

Three short sentences: effect first, then the invocation gate. Every clause carries information and the most important constraint is front-loaded alongside the outcome.

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?

Output schema exists, so return values need not be described, and the description covers the effect and the gating condition for a simple one-parameter action. It could be more complete by tying recap_id to the drafting tool and stating whether approval fails if no recap exists.

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% for the single required 'recap_id' (uuid). The description adds no meaning about the parameter at all, not even how to obtain a recap ID (presumably from visits_draftRecap or visits_get). With the schema providing no documentation, the description should have compensated and does not.

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 and resource ('approves the recap') and immediately explains the resulting action: an email to the customer from the shop with replies routed to the shop owner. It is clearly distinguishable from drafting/editing siblings like visits_draftRecap and visits_editRecap by virtue of the send effect, though it never names those siblings explicitly.

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 an explicit and emphatic precondition: 'Call only after the worker says send it. Never call on your own.' This is a clear when-to-use and when-not-to-use rule. It stops short of naming alternatives (e.g., use visits_editRecap to change content first), which keeps it from a 5.

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