create_deployment

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does not mention side effects (e.g., triggering CI), required permissions, reversibility, or the outcome of creation. The simple verb 'create' implies a mutation, but no other behavioral traits are disclosed.

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, concise sentence with no redundant words, making it efficient. However, given the tool's 11-parameter complexity, the one-line description may be too terse to serve as an adequate standalone guide, though it is not under-specified to the point of being meaningless.

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 has 11 parameters, no annotations, and no output schema, yet the description only provides the basic action. It omits essential context such as what a deployment is, parameter semantics, and usage conditions, making it incomplete for an agent to correctly invoke without external knowledge.

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 only 9% (only 'ref' has a description in the schema), and the tool description adds no information about any of the 11 parameters. The description does not compensate for the low schema coverage, leaving the agent with minimal understanding of parameter meaning or relationships.

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 ('Create') and the resource ('a deployment') with scope ('for a repository'), distinguishing it from sibling creation tools like create_repository, create_release, and create_pull_request. The verb+resource is specific and unambiguous.

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 provides no guidance on when to use this tool, prerequisites, or alternatives. It only states what it does, leaving the agent to infer context from the schema or sibling tools without any explicit direction.

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