Register ci lifecycle operator

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

Annotations declare readOnlyHint=false, idempotentHint=false, destructiveHint=false, and openWorldHint=true, so the mutation and safety profile is partly covered. The description adds the useful constraint that only non-workflow users can be registered, but it does not disclose side effects, auth requirements, or what happens on repeated calls.

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 short sentence and is front-loaded with the core action. It contains no wasted words, though its extreme brevity leaves no structural room for required usage or parameter context.

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 two undocumented parameters, no output schema, and is part of a complex CI lifecycle family. The description gives only the minimum purpose statement and omits prerequisites, parameter meaning, and behavioral details that an agent would need to invoke it correctly.

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% and the description does not mention either parameter. With two parameters, including an arbitrary object schema, the description provides no semantic guidance about what to pass for 'params' or 'params_json'.

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 clear verb ('Registers') and resource ('operator') and adds a scope qualifier ('for a non-workflow user'). It is distinguishable from the sibling unregister_ci_lifecycle_operator, but it does not explain what an 'operator' is in the CI lifecycle context or distinguish it from other lifecycle actions.

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 gives no when-to-use guidance, prerequisites, or alternatives. It does not explain when registering an operator is appropriate versus using other CI lifecycle tools such as add_ci_lifecycle_action or unregister_ci_lifecycle_operator.

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