C2.4/5.0

Behavior2/5

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

The annotation readOnlyHint=false already indicates this is a write operation, and the description's 'Create' is consistent with that. However, the description adds no additional behavioral context, such as irreversibility, permission requirements, or side effects like overwriting existing data. Since the annotation covers the read-only aspect, the description fails to add any further transparency value.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely terse, consisting of only three words. While it is concise in wording, it is under-specified and lacks any structured information or front-loading of critical constraints. It is not an example of efficient, valuable conciseness but rather of insufficient elaboration.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's moderate complexity (nested body object, path params, required fields, no output schema), the description is severely incomplete. It does not mention return values, error conditions, or any validation requirements. The absence of parameter descriptions and behavioral context makes this definition inadequate for reliable agent use.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, meaning the schema provides no descriptions for any parameters. The description 'Create issue category' does not explain any parameter semantics, such as what 'format', 'projectId', 'issue_category', 'name', or 'assigned_to_id' mean or how they relate. Without compensation from the description, an agent has no guidance on parameter usage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource ('Create issue category'), which distinguishes it from sibling tools like getIssueCategory, updateIssueCategory, and deleteIssueCategory based on the action. However, it provides no additional detail about what the category entails, so it lacks the richness expected for a 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives no guidance on when to use this tool versus alternatives. It does not mention prerequisites, context, or conditions that would help an agent decide between creating, updating, or deleting a category. No exclusions or recommendations are provided.

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