save_profile

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

With no annotations, the description carries the full burden, and it discloses several important behaviors: lenient number coercion, path expansion, empty values clearing a field, and the warnings/unknown_keys semantics. It could additionally clarify whether the profile is merged or replaced, but the disclosed traits are substantive and clearly stated.

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 leads with a one-sentence purpose, then uses compact paragraphs for value parsing and response semantics. Each section earns its place and is not overly verbose for a parameter with meaningful edge cases.

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 one-parameter nested-object tool with an output schema, the description covers the essential value-coercion rules and the warning/unknown_keys response contract. It is operationally sufficient for correct invocation, though selection guidance relative to update_profile is absent.

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 coverage is 0%, and the only parameter is an opaque answers object with additionalProperties. The description compensates well by explaining how values map to field keys, accepted boolean forms, number coercion, path resolution, and clearing behavior, though it does not enumerate valid keys.

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 opens with 'Store setup answers in the user's profile file,' which identifies a clear action and resource. It is specific enough to indicate a write operation for setup data, but it does not explicitly distinguish this from siblings like update_profile or record_answer.

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 guidance on when to use save_profile versus update_profile or record_answer. The description implies it is for setup answers but gives no decision rules, exclusions, or alternatives, leaving the agent to infer the appropriate scenario from the name alone.

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