Mhs Health Check

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

Annotations already declare readOnlyHint=false, idempotentHint=true, destructiveHint=false, so the safety profile is covered. The description adds context that it acknowledges a failed-write gate (consistent with a non-read-only operation) but does not clarify what state changes, whether acknowledgement is reversible, or what a 'fresh simulated' inspection returns.

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?

A single compact sentence with the action front-loaded. However, the second clause is dense and cryptic rather than informative, slightly reducing value per word.

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?

An output schema exists, so return values need not be described. Still, the description leaves the core mechanics ('health gate', 'acknowledge', 'mhs') unexplained for a tool in a family with five siblings, so an agent lacks enough to call it confidently.

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?

With a single optional parameter and 100% schema description coverage, the schema already documents device_id and its 'omit for all devices' default. The description adds no semantics beyond the schema, so baseline 3 applies.

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 verb 'inspect' and resource 'health' are present, but 'mhs' is never expanded and the second clause ('acknowledge a failed-write health gate') is cryptic enough that an agent cannot cleanly predict what the tool does. It fails to distinguish itself from siblings like mhs_read, mhs_reset, or mhs_meta_info.

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 statement of when to call this versus mhs_read/mhs_write/mhs_reset, and no exclusion criteria or prerequisites. The phrase 'failed-write health gate' hints at a trigger condition but never explains it as guidance.

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