households_event_notifications_update_one

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

No annotations are provided, so the description carries the full burden. The only behavioral signal is '(full update)', which usefully implies omitted fields may be overwritten/reset, but there is nothing on permissions/auth, idempotency, validation failures, or side effects of changing notification options. This is too thin for an unannotated mutation tool.

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 operational sentence and the PUT path are front-loaded and useful, but the bulk of the text is auto-generated keyword stuffing ('update notification, replace notification, edit notification, modify notification, save notification, write notification ...' and a duplicated noun list) that adds no selection value and bloats the definition.

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?

A mutation endpoint with no annotations, no output schema, 0% parameter description coverage, and a large nested options object. The description neither explains what a full replace does to unspecified option flags nor what happens after the call, so an agent lacks what it needs to invoke this correctly.

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% and the description says nothing about the two required parameters (item_id, body) — not their format, not that body must be a complete replacement object, not the meaning of the many event-option booleans. The description fails to compensate for the coverage 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?

The first two sentences state a specific verb and resource ('Update One — Households: Event Notifications', 'Replace (full update) notification') and the parenthetical distinguishes it from a partial/PATCH update. An agent can tell which record type and which operation is meant, though siblings like update vs create/delete are not explicitly contrasted.

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?

There is no statement of when to use this tool versus households_event_notifications_create_one, _get_one, _delete_one, or a partial-update variant. The 'Replace (full update)' phrasing hints at semantics but gives no conditions, prerequisites, or exclusions. Everything is left to infer from the name.

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