v0.2.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds that it returns the full SCIM User resource but says nothing about error behavior, missing users, or permissions. Some added value but not rich.
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 concise sentences with the core action front-loaded and no wasted 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?
For a simple read-by-ID tool with annotations covering safety and a fully documented parameter, this is adequate. However, it lacks any disambiguation from the many similar get/list siblings and does not mention what a missing user returns.
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 coverage is 100%, so the single user_id parameter is fully documented in the schema. The description repeats that user_id identifies the user but adds no format, constraints, or examples beyond the 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 states a specific verb (Retrieve) and resource (SCIM user by user_id), and clarifies the return payload is the full SCIM User resource. It does not explicitly differentiate from sibling get_user or scim_list_users, but the SCIM and single-user scope makes it reasonably distinct.
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?
No guidance on when to use this versus alternatives like get_user, scim_list_users, or scim_get_group. The description implies fetching a single user by ID but offers no context or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
