jira_create_subtask

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

Annotations already declare readOnly=false, destructive=true, idempotent=true, and openWorld=true. The description adds useful context about governed routing, Spring verifying the claimed effect, and approval_ref for resuming writes. However, it does not describe concrete side effects such as what subtask fields get written or how the Jira parent issue is resolved.

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 compact, front-loaded with the operation identity and governance constraint, followed by a clean parameter list. There is no fluff or redundancy. It loses a point because the most important payload parameter, arguments, is described only as a generic JSON string rather than with any useful substructure.

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?

Despite having an output schema and annotations, the description lacks the core Jira-specific semantics needed to invoke the tool correctly: no guidance on specifying the parent issue, required subtask fields, project identification strategy, or payload example. It reads like a generic connector-wrapper template rather than a definition for actually creating a subtask.

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?

With 0% schema description coverage, the Args list carries the parameter documentation burden and gives each parameter a one-line meaning, such as arguments being a JSON string and approval_ref being an approved platform task UUID. This is helpful but shallow: it does not explain the required structure of the arguments JSON for creating a Jira subtask, nor what values like project_ref and connector_account_ref should contain.

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 mostly restates the tool name as "Jira connector operation `create_subtask`" without explaining what a subtask is or what the operation accomplishes. The added "Routes only through the exact project/account governed connector authority" line describes routing governance, not the core purpose. It also does not differentiate this from siblings like jira_create_issue.

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 when-to-use or when-not-to-use guidance is provided, and no alternatives are mentioned. An agent cannot determine when to choose this over jira_create_issue or other Jira tools. The governance constraint is the only contextual hint, but it is not a usage criterion.

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