jira_get_user_profile

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

With no annotations, the description carries the transparency burden. It discloses return behavior ('JSON string representing the Jira user profile object, or an error object if not found') and a raised ValueError when the Jira client is unavailable, providing useful behavioral context beyond the input schema.

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 compact docstring with clear sections (Args, Returns, Raises) and front-loads the purpose. It is slightly redundant by repeating parameter info already in the schema and listing ctx, but overall it is well-organized and not overly verbose.

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 one-parameter lookup tool, the description is complete: it states the purpose, return format, error behavior, and a key prerequisite (client configuration). It covers essential information an agent needs to invoke and interpret the result without relying on an output schema.

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 describes user_identifier in detail with examples, so the description adds little new parameter meaning. It repeats the identifier types and also lists 'ctx' in Args even though ctx is not part of the input schema, which is a minor source of confusion; schema coverage is 100%, so the baseline 3 applies.

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 begins with a specific action and resource: 'Retrieve profile information for a specific Jira user.' This clearly states what the tool does and is distinct from sibling tools like jira_get_issue or jira_get_project_issues, which target different resources.

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 gives clear context by specifying 'for a specific Jira user' but does not explicitly mention when not to use it or alternative tools. It implies this is the go-to tool for fetching a user profile, but lacks explicit exclusions or references to alternatives.

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