safety_status

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

The annotations already declare readOnlyHint, destructiveHint=false, and openWorldHint=false, so the safety profile is largely covered. The description adds real value beyond that by listing the six categories of information returned and framing the tool as an aggregate snapshot, which tells the agent this is a broad read rather than a targeted query. It does not mention whether results are cached or how recent the data is, keeping it below a 5.

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 purpose is front-loaded in the first sentence, followed by a compact enumerated list of returned contents and a closing use-case sentence. Every sentence earns its place; the only minor waste is the multi-line indentation formatting.

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?

There is no output schema, so the description carries the burden of explaining return values, and it does so by enumerating all six components of the snapshot. Combined with annotations covering safety semantics and zero parameters, an agent has enough to call it correctly. A brief note on freshness or scope (per-printer vs. fleet) is the only gap.

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?

The tool takes no parameters, so the baseline is 4. The description correctly implies a parameterless, single-call aggregate, and nothing in the schema requires further explanation.

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 opens with a specific verb and resource: 'Get a comprehensive snapshot of all active safety measures.' It then enumerates the exact contents of the snapshot (profile, temperature limits, rate limits, blocked actions, auth status, confirmation mode), so an agent knows precisely what this tool returns. It does not name the sibling tools (safety_audit, safety_settings, get_safety_profile) it differs from, so it falls 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?

It offers a concrete use case, answering 'is my printer safe right now?', and frames itself as a one-call aggregate, which implies it replaces multiple narrower status calls. However, it never names an alternative or states when not to use it, so the routing guidance is implied rather than explicit.

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