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

No annotations are provided, so the description must disclose behavioral traits. It states the tool reads or updates the profile but doesn't mention potential side effects, permission requirements, or that updating could overwrite existing data. The update operation is implied but lacks transparency about consequences.

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 sentences: the first lists what you get, the second explains how to update. Information is front-loaded and every sentence serves a purpose. No verbose or redundant content.

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?

The tool has 7 parameters and no output schema. The description covers the basic use cases but doesn't describe return values, error conditions, or how the update interacts with existing data. For a combined get/update tool, the description is sufficient but lacks depth for a user to fully anticipate behavior.

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 100%, with each parameter explaining it's used for the update action. The description adds context by instructing to set action to 'update' and include fields to change, but this largely mirrors the schema. Baseline 3 is appropriate since the schema handles parameter documentation.

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 a specific verb and resource: 'Get your service provider profile' and enumerates key fields. It clearly distinguishes from sibling tools by referring to 'service provider profile' and explains the update capability with the action parameter. Though it mixes get/update, the dual purpose is explicit and unambiguous.

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 provides direct usage guidance: use 'get' to read your profile, and set action to 'update' to modify it. It gives clear context for both modes but doesn't mention alternatives or when not to use this tool, such as the relationship to agentlux_profile or agentlux_set_profile_visibility.

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