create_release

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

The description adds the useful behavioral note that omitting status defaults to 'planned', and it explains what releases aggregate. However, aside from the all-false annotations, it does not disclose idempotency, duplicate-creation behavior, permission requirements, or what the tool returns after creation.

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 and front-loaded: the first sentence states the core action, the second adds domain context, and the third conveys the most important invocation nuance. No filler or redundant phrasing.

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?

Combined with a fully documented schema and the explicit default-status behavior, this description provides enough context for an agent to call the tool correctly. The main gap is the absence of any information about the expected response shape, since no output schema exists.

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 100% schema description coverage, the schema already fully documents all 7 parameters, including status default, formats, and examples. The description notes the status default again but does not add meaningful parameter-level information beyond the 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 clearly states the action and resource: 'Create a new release in a project.' It also explains what releases are for ('track versions and aggregate manual and automated test results'), which distinguishes this from create_execution, create_suite, and other create tools.

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 intended use is implied through the description of what a release is, but there is no explicit guidance on when to choose create_release over update_release, link_launches_to_release, or list_releases. No exclusions or alternative selection criteria are stated.

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