deploy_app

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, but it only says 'Trigger deployment.' It does not state whether deployment is asynchronous or blocking, whether it rebuilds the service, whether it causes downtime, or how the result is reported.

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 short and front-loaded with the primary action. Every word contributes, but the brevity comes at the cost of useful context, making it concise rather than substantively efficient.

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?

For a deployment action with no annotations, no output schema, and a sibling set full of lifecycle tools, the description is incomplete. It does not mention result format, error cases, async behavior, or how to monitor the deployment, leaving important operational questions unanswered.

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 parameters. The description adds no meaning beyond the schema's minimal 'Project name' and 'Service name,' so the baseline 3 applies.

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 names a clear verb-resource pair ('Trigger deployment' for 'an app'), and the tool name confirms it targets a single app. It is differentiated from deploy_compose and deploy_template by naming 'app' as the resource, though it does not explicitly define what counts as an app deployment.

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 use this tool versus start_app, restart_app, deploy_compose, or deploy_template. The description is a one-line action statement with no conditions, prerequisites, or exclusions, leaving the agent to infer deployment semantics from the tool name alone.

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