update-predefined-variations

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

No annotations provided. Description only mentions one constraint; lacks disclosure of side effects, error handling, or response behavior. Limited value beyond the constraint.

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?

Two concise sentences, with key constraint highlighted in bold. Adequately front-loaded but could include more essential details without becoming verbose.

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?

Missing important behavioral details like return values, error scenarios, and idempotency. Without annotations or output schema, the description is insufficient for comprehensive understanding.

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 has 50% description coverage, with descriptions for nested fields. The description adds context about the settingId parameter and the update constraint, but does not elaborate on requestBody structure beyond schema.

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?

Clearly states that the tool updates predefined variations for a Feature Flag or Setting identified by settingId. Does not explicitly differentiate from sibling tools like update-setting, but the mention of 'predefined variations' provides specificity.

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?

Provides a critical constraint ('only update if not used in any feature flags') but does not offer guidance on when to use this tool versus alternatives or prerequisites.

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