enable_rule_based_segment_definition

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

Without annotations, the description carries full burden. It states it creates an empty definition, but does not disclose required permissions, side effects (e.g., whether it overwrites existing definitions), or if it's idempotent. For a mutation tool, more behavioral details are needed.

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 that front-loads the main action and adds essential context. Every word earns its place, with no redundancy.

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 description covers the basic purpose and the creation of an empty definition, but lacks details on return values, error conditions, or prerequisites. Given the tool's simplicity and good schema coverage, it is adequate but not fully 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 coverage is 100%, so baseline is 3. The description does not add any parameter-specific information beyond what the schema provides, but it is not misleading.

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 verb 'Enable (activate)' and the resource 'rule-based segment in a specific environment'. It also adds that it creates an empty definition for later configuration, which clarifies the one-time setup nature. However, it does not explicitly differentiate from siblings like 'create_rule_based_segment', which might also create definitions.

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 need to enable a segment and create an empty definition for later update. It mentions 'can then be configured via update', giving context on subsequent steps. But it lacks explicit when-not-to-use or alternatives, such as 'disable_rule_based_segment_definition'.

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