skylight_update_family_member

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

No annotations are provided, so the description must disclose behavioral traits. It only states 'Update' without mentioning any side effects (e.g., overwriting existing data, permissions required, or error conditions). This is insufficient for safe invocation.

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 sentences, no wasted words. The first sentence states the purpose and key parameters; the second provides a critical cross-reference. Well-structured 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?

No output schema exists, so the description should clarify what the tool returns (e.g., the updated member). It does not. Additionally, two of four parameters (frameId and dietary_preferences) lack explanation. The description is incomplete for safe and correct usage.

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 50%. The description adds meaning by naming birthday and dietary preferences as updatable fields, partially compensating for the missing schema descriptions. However, it ignores frameId entirely, and the id parameter is only implied as the identifier.

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 tool updates a family member's profile, specifically birthday and dietary preferences. It distinguishes from skylight_update_category by noting that the member's name is set via that tool. However, it does not mention the optional frameId parameter, which could cause minor confusion.

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 explicitly advises when to use this tool (to update birthday/dietary preferences) and directs the user to skylight_update_category for name changes. It lacks explicit exclusion of other use cases, but the context is sufficient for most agents.

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