Create release (milestone)

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

Annotations are absent, so the description must carry the behavioral burden, but it only restates the basic create action. It does not mention duplicate-name handling, permissions needed, whether the operation is idempotent, or what side effects occur. This is a minimal description with no additional behavioral disclosure.

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 a single, front-loaded sentence with no filler. It includes the core action plus a clarifying parenthetical and scope.

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?

The tool is simple with only two fully documented parameters, so the schema covers invocation basics. However, with no output schema and no annotations, the description omits expectations about return values and edge cases such as duplicate releases. For a mutation tool, a bit more context would be needed for a higher score.

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?

Schema description coverage is 100%, so the schema already documents both projectKey and milestone. The description adds no parameter-specific details beyond naming the resource. Baseline 3 is appropriate.

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 specific action ('Create') and target resource ('release (milestone)') and scopes it to a project. This makes it clearly distinct from sibling create tools aimed at projects, tests, modules, defects, etc. It does not confuse it with list_releases because the verb differs.

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 guidance on when to choose this tool over alternatives such as list_releases, or on any prerequisites like requiring an existing project. The only signal is the generic action in the description, leaving the agent to infer usage.

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