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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states this is an update operation, implying mutation, but doesn't describe permissions required, whether changes are reversible, error handling (e.g., for invalid user IDs), or response format. For a mutation tool with zero annotation coverage, this is a significant gap in transparency.

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 a single, efficient sentence that front-loads the core purpose. It avoids unnecessary words and focuses on the key action and fields. However, it could be slightly more structured by explicitly listing all updatable fields or adding brief context, but it earns high marks for brevity.

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?

Given this is a mutation tool with no annotations and no output schema, the description is incomplete. It lacks information on permissions, side effects, error cases, and what the tool returns. For a tool that modifies user data, more context is needed to ensure safe and correct usage by 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?

Schema description coverage is 100%, so the schema already documents all parameters (user_id, first_name, last_name, role) with descriptions and enum values for 'role'. The description adds minimal value by mentioning 'name and organization role', which loosely maps to parameters but doesn't provide additional syntax, constraints, or examples beyond what the schema provides. Baseline 3 is appropriate when schema does the heavy lifting.

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 the verb ('update') and resource ('user's profile information') with specific fields mentioned ('name and organization role'). It distinguishes from sibling tools like 'delete_user' or 'get_user' by specifying an update operation. However, it doesn't explicitly differentiate from similar update tools like 'update_workspace_member' which might also modify user roles in a different context.

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 no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing admin permissions), exclusions (e.g., cannot update certain fields), or comparisons to sibling tools like 'update_workspace_member' for workspace-specific roles versus organization-level roles. Usage is implied but not explicitly stated.

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