TDQS

C2.1/5.0
Behavior2/5

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

With no annotations provided, the description carries the full disclosure burden, and 'Create component' only signals a mutating operation — information already carried by the name itself. It says nothing about permissions, side effects, idempotency, or what happens on duplicate names. Slightly more informative than a bare noun but far short of what an unannotated mutation tool requires.

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?

Two words with no redundancy, but this is under-pecification rather than conciseness. A tool with a 16-field nested request body and no output schema cannot be usefully described in a single phrase. There are no sentences earning their place because there is effectively no content.

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

Completeness1/5

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

Completely inadequate for the tool's complexity: no output schema, no annotations, a nested object parameter, and 60+ siblings to disambiguate from. An agent has no way to know what a component is, which fields matter, what the response contains, or how this differs from create_version or create_issue. Nothing necesary for correct invocation is conveyed.

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

Parameters3/5

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

Schema description coverage is 100% at the top level, meeting the >80% threshold, so the baseline of 3 applies even though the description adds nothing about parameters. The body description 'Request body (JSON object)' is generic, and none of the 16 nested fields are documented in the description, but the rule grants baseline credit for the covered schema. The description itself contributes zero semantic value beyond the schema.

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

Purpose2/5

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

The description 'Create component' is a near-verbatim restatement of the tool name 'create_component', making it a tautology. It fails to specify what kind of component (Jira project component, implied by the sibling set) or how it differs from the many other creation tools. No resource scope, context, or differentiating detail is provided.

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?

There is zero guidance on when to invoke this tool versus alternatives like create_version, create_issue, or get_project_component. No context, conditions, exclusions, or alternative routing is offered anywhere in the description.

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