Ring recap health

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

Annotations already establish readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds some behavioral color by implying heuristic judgments ('looks enabled') and by referencing live vs cached state, but it never states that live checks hit the Ring service (latency, auth requirements, failure modes) or what happens when auth is broken.

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?

One dense sentence with no filler; every listed item is a real returned datum. It is a flat noun list rather than front-loaded with a purpose statement, which slightly hurts scanability, but nothing is wasted.

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?

With no output schema, the description carries the burden of describing return values, and it does so by enumerating the reported fields, including the scoping detail 'last 7 days' for failed clips. It is missing result format/keys and behavior on partial failure, but for a read-only one-param status tool this is close to sufficient.

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 100% and the single 'live' parameter is fully documented in the schema, so the baseline is 3. The description adds nothing about the live/cached tradeoff and doesn't tell the agent when to prefer the cheaper cached path.

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 enumerates the concrete data the tool surfaces (auth state, last run, offline cameras, failed clips, vault size, disk, encryption status), which makes the purpose — a health/diagnostics snapshot — inferable without opening the schema. It lacks an explicit verb phrase like 'report' and never contrasts itself with list_cameras or sync_day, so it stops short of a 5.

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?

There is no when-to-use guidance, no exclusions, and no mention of the sibling tools. An agent must infer that this is a pre-flight/diagnostic check rather than, say, a data-retrieval tool; the only usage hint is the 'live' parameter's default, which lives in the schema, not the description.

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