ruddur_update_creator_profile

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

Annotations already indicate non-readOnly and non-idempotent, and the description adds valuable context about alias acceptance and required scope. It does not fully explain the create-vs-update decision logic, but the added auth and parameter behavior details go beyond what annotations provide, with no contradictions.

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 concise, with three short sentences that front-load the main purpose and then provide relevant alias and scope details. There is no redundant or irrelevant content; every sentence earns its place.

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 no output schema and the input schema is generic, so the description carries a heavier burden. It covers the core operation and scope, but misses key details like whether the tool creates missing profiles or updates existing ones, and what the return value is. Given the mutation nature and generic schema, more behavioral specifics would be needed for full completeness.

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?

The schema has 100% coverage, but the body description is generic and even mentions 'waypoint payloads', which is irrelevant to profiles. The description adds specific meaning by stating that name, creatorName, and title are aliases for displayName, but it does not enumerate other profile fields, so it only partially compensates for the generic schema.

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 'Create or update the authenticated creator profile' with a specific verb and resource, making the tool's function immediately obvious. It also distinguishes itself from sibling 'ruddur_get_creator_profile' by indicating a write operation, and the alias detail further clarifies the purpose.

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 implies usage for creating/updating the creator profile and provides an access requirement ('Requires scope: marketplace.manage'), which is useful context. However, it does not explicitly compare to alternatives like ruddur_get_creator_profile or state when not to use this tool, so it offers clear context without exclusions.

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