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

Annotations already declare readOnlyHint=true, openWorldHint=false, and destructiveHint=false, so the safety profile is covered. The description adds intent categories but does not disclose behavior like ordering, aggregation semantics, or how the inbox relates to other views; this is acceptable but not rich.

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 front-loaded sentence with no wasted words. It immediately states when to use the tool and lists concrete user phrasings, making it efficient and easy to parse.

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 presence of an output schema and fully documented parameters reduces the burden on the description. Still, the description overlaps with familia_list_past_due by including 'overdue tasks' and does not clarify the boundary between the inbox and other sibling tools, so contextual routing is 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?

All three parameters are already fully described in the schema with defaults and semantics, so schema coverage is 100%. The description adds no parameter-level meaning beyond the general 'what is waiting on them' context, matching the baseline for fully documented params.

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 identifies the resource as 'inbox / items needing attention' and provides a specific verb (get) plus a broad list of user intents. However, it does not explicitly differentiate this from overlapping siblings like familia_list_past_due or familia_get_next_up, so the distinction relies on inference.

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 explicit when-to-use guidance by enumerating trigger phrases such as 'inbox', 'items needing attention', and 'overdue tasks'. It does not mention when not to use it or name alternatives, so exclusion criteria are missing.

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