create_jira_instance

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

No annotations are provided, so the description carries the full behavioral burden for a creation/mutation tool. It does not disclose whether credentials are stored, whether the tool validates a live JIRA connection, what side effects occur, or what permissions are needed. Only the parameter list adds any substance, which is semantic rather than behavioral.

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 purpose statement is front-loaded in a single line, followed by a clean Args block. Given the 0% schema coverage, enumerating the parameters earns its place. It is slightly list-heavy but wastes no words.

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?

An output schema exists, so return values need not be described. For a 12-parameter mutation tool with no annotations, the parameter documentation is adequate but the description omits prerequisites, auth expectations, and side-effect behavior, leaving meaningful gaps.

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 description must compensate and largely does: it explains all 12 parameters, including non-obvious ones like epic_name_id ('Custom field ID for epic name'), open/close_status_key ('Transition ID'), and the severity-to-priority mappings. It adds real meaning beyond the bare schema titles, though it omits format details (e.g., expected URL format, integer ID ranges).

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 opens with a clear specific verb and resource: 'Create a new JIRA instance configuration.' An agent can distinguish this from read siblings like get_jira_instance and list_jira_instances. However, it does not explicitly name or contrast with those siblings, so it earns a 4 rather than 5.

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?

There is no when-to-use guidance, no prerequisites (e.g., required JIRA server access or admin permissions), and no mention of alternatives such as get_jira_instance or list_jira_instances. The description simply asserts what the tool does without helping the agent decide when to select it.

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