service_create_from_repo

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

Description mentions it's an API call and requires prerequisite project_list, but doesn't detail potential side effects (e.g., costs, permissions, rebuild times). No annotations provided to compensate.

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?

Well-structured with sections, emojis, and arrows for clarity. Some redundancy in arrows, but overall efficient and front-loaded.

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?

Covers prerequisites, alternatives, and next steps. Missing output schema and error handling, but for a creation tool it's fairly complete.

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 covers 100% of parameters with descriptions. Description adds no extra parameter-level detail beyond what schema already provides.

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 'Create a new service from a GitHub repository', specifying the action (create), resource (service), and source (GitHub repo). It distinguishes from siblings like service_create_from_image and database_deploy.

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?

Explicit sections for 'Best for', 'Not for', prerequisites, alternatives, next steps, and related tools provide comprehensive guidance on when to use and avoid this tool.

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