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

Annotations already declare the write/idempotent/destructive profile, so the description's added value is the downstream effect: the entry is consumed by the next WhatsApp reply and the next phone call. That tells the agent this is live behavioral configuration rather than inert metadata, which is useful context beyond the annotations. It stops short of saying whether an existing entry's prior body is replaced or merged.

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 short, front-loaded sentences with no padding; the operation is stated first and the side effect second. It is well-sized, though the brevity is partly what leaves the parameter space undocumented.

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, six-parameter mutation with a nested object, an enum, zero schema descriptions, and no output schema, the description covers only the high-level effect. Nothing tells the agent how the fields combine or what a successful call returns or changes, leaving notable gaps.

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% across six parameters, and the description says nothing about any of them beyond the general 'one receptionist' scoping. It does not explain what id does versus title/body, how the nested data object relates to the enum-constrained category, or which fields are required to create versus revise.

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 operation (adds or revises) on a specific resource (a knowledge entry for one receptionist), which maps cleanly to the upsert_ verb in the name. It is distinguishable from read-oriented siblings like get_receptionist_facts and delete_receptionist_knowledge, though it does not name any sibling 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?

There is no explicit when-to-use or when-not-to-use guidance and no named alternative. The phrase 'for one receptionist' implies the entry is scoped to a single configuration, but the agent is left to infer when this tool is preferred over upsert_receptionist_profile, upsert_receptionist_location, or upsert_receptionist.

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