Create private deploy key application

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

Annotations are None, so the description carries the full burden. It only says 'Create a new application' and lists required fields. It does not disclose auth permissions, side effects, idempotency, or response behavior. For a state-changing operation with no annotation safety hints, this is a notable gap.

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 entire description is one sentence, front-loaded with the main action, and packs the essential required fields without redundancy. It earns its place with no fluff. It is efficient and easy to parse.

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 69 parameters, no output schema, and no annotations, making it high complexity. The description only covers 8 of 69 parameters, omits the 'or' logic for environment_name/environment_uuid in a structured way, and gives no information about response, errors, or deployment behavior. This is incomplete for guiding an AI agent.

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 0%, so the description must compensate. It lists 8 required parameter names but does not explain their meanings or types. It does add one critical clarification: 'environment_name (or environment_uuid)' implies an either/or relationship, which contradicts the schema's required list that includes both. Still, with 69 total parameters, this is inadequate coverage.

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 a specific verb and resource: 'Create a new application using a private SSH deploy key.' This clearly distinguishes it from sibling tools like createPrivateGithubAppApplication (which uses a GitHub App) and createDockerComposeApplication (which uses Docker Compose). It also lists the key required fields, making the purpose evident.

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 implies usage when you have a private SSH deploy key, which differentiates it from other creation tools. It also lists prerequisites (project_uuid, server_uuid, etc.), giving context. However, it does not explicitly exclude alternatives or say 'use this instead of X', so it stops short of a 5.

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