jira_get_user_profile

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

With no annotations, the description carries the full burden. It discloses that the tool returns a JSON string or error object, and raises ValueError if client is not configured. However, it omits details on rate limits, authentication, or what happens with ambiguous identifiers. It provides moderate 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 concise, structured with Args/Returns/Raises sections, and front-loaded with the core purpose. It is slightly longer than necessary due to the docstring format, but overall efficient and clear.

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 the simplicity of the tool (one parameter, no nested objects), the description covers return type and error conditions. It mentions the return is a JSON string representing the user profile, which is sufficient. However, no output schema is provided to verify completeness, so a slight deduction.

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 input schema already provides a detailed description of the user_identifier parameter (including examples). The tool description does not add additional semantic meaning beyond what the schema provides. Schema coverage is 100%, so baseline score of 3 is appropriate.

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 action ('Retrieve profile information') and the resource ('a specific Jira user'). It is distinct from sibling tools like jira_get_issue or jira_search, which deal with issues or searches, not user profiles.

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 like jira_search (which could also retrieve user info) or when not to use it. There is no mention of prerequisites or context for effective use.

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