update_profile

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

No annotations are provided, so the description carries the full burden. It correctly states the merge semantics, but does not disclose potential side effects, permissions, or return value behavior, which is a gap for a 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 description is two sentences, front-loaded with the verb and resource, and each sentence adds value. No unnecessary words.

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?

Despite the complexity of 15 parameters nested objects and no annotations or output schema, the description is minimal. It does not explain return values, error handling, or how the merge interacts with existing data, leaving significant gaps for an AI agent.

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?

With 0% schema description coverage and 15 parameters including nested objects, the description only mentions two example fields ('unlisted_skills', 'dealbreaker_detail'). It adds the merge behavior but does not explain the meaning or constraints of the many other parameters.

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 clearly states 'Update the user's profile' with a specific verb and resource, and distinguishes from siblings like 'get_profile' and 'setup' by highlighting the merge behavior without full re-setup.

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 explains that the tool accepts any subset of fields and merges them, implicitly distinguishing it from read tools and full setups. It provides concrete examples like 'unlisted_skills' and 'dealbreaker_detail', but lacks explicit when-not-to-use guidance.

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