create_release

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

Annotations already indicate readOnlyHint=false, destructiveHint=false, and idempotentHint=true, covering the safety and mutation profile. The description adds the tip to consult GET/schema endpoints, which is a behavioral note about how to construct the request. It does not mention idempotency or what happens on duplicate creation, but with annotations present, the added value is modest.

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 extremely concise and well-structured. It leads with the action, provides the exact HTTP endpoint, and gives a clear instruction for handling the body parameter. Every sentence serves a purpose, and there is no redundancy.

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?

Given that an output schema exists and the tool is a straightforward creation POST, the description is adequate but not rich. It does not describe the return value (though the output schema covers that), nor does it mention authentication or error scenarios. The pointer to GET/schema is important, but more context about expected behavior (e.g., idempotency confirmation) could be added. Overall, it is minimally complete for an agent that can follow the schema-reading instruction.

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 only parameter is 'body', an open object with additionalProperties true. The schema provides no field details (0% coverage), so the description's guidance to read the matching GET or /schema endpoint is essential and adds real meaning. It tells the agent how to discover the required fields, partially compensating for the sparse schema.

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 states the verb and resource clearly: 'Create Release.' It is distinct from siblings like create_release_push or create_releaseprofile, though it does not explicitly differentiate them. The purpose is unambiguous enough for an agent to know it creates a release resource.

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 a useful prerequisite: 'Read the matching GET or the /schema endpoint first to see the fields this resource expects.' This tells the agent how to prepare, but it does not explain when to choose this tool over alternatives (e.g., create_release_push) or any exclusion criteria. The guidance is implied rather than explicit.

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