A3.7/5.0

Behavior4/5

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

Annotations declare readOnlyHint=false and destructiveHint=false, but the description goes further and discloses a partially destructive sub-behavior: sending skills wipes and replaces the entire list. That is exactly the kind of trap an agent needs warned about and that annotations cannot express. It omits auth expectations (the api_key parameter) and rate limits.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, no filler, with the general contract first and the one hazardous exception (skills) last. Every sentence carries information the agent cannot get elsewhere.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 20-parameter mutation tool with no output schema and no annotations covering auth, the description is thin: it does not say what is returned, whether a field can be cleared once set (an empty string or null), or how the api_key parameter interacts with the Authorization header. The safety-relevant replacement caveat is present, but the clearing question is left open.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% across all 20 parameters, so the schema already carries per-field meaning and the baseline applies. The description adds only cross-parameter semantics: omitted fields are untouched, and skills is a whole-list replacement rather than a merge.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

"Change any profile field" gives a specific verb (change) and resource (own profile), which cleanly separates it from get_my_profile and from the project/experience siblings. It stops short of naming any sibling explicitly, so the distinction rests on the verb alone.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The partial-update rule ("Only the fields you send change") tells the agent how to call it safely, which implies when it is appropriate. There is no stated when-not condition and no mention of what to use instead for reading the profile back.

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