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

No annotations are provided, so the description carries the behavioral burden. It makes clear this is a write operation and adds a useful behavioral detail (voice_provider defaults to Edge TTS), but it does not disclose whether existing settings are fully replaced, what happens when optional fields are omitted, or what response/error behavior to expect.

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 with no fluff. The first sentence states the action and fields, and the second adds a key default; information is front-loaded and every word earns its place.

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?

For an 8-parameter mutation tool with no annotations and no output schema, the description gives enough to select the tool but leaves important invocation context (save/overwrite semantics, response/errors) to inference. The schema covers parameter details, so the gap is moderate.

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%, so the baseline is 3. The description adds only high-level grouping and a default for voice_provider; it does not compensate for or add much beyond the already-complete schema parameter descriptions.

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 uses a specific action ('Save') and identifies the exact resource ('user's CEMAS destination phone(s), active flag, and voice prefs'), making the tool's purpose unambiguous and easily distinguishable from siblings like getCemasConfig and the call-making tools.

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 clearly implies this is the configuration-persistence tool, but it does not explicitly say when to use it instead of getCemasConfig, updateProfile, or call tools, and it gives no exclusions. Usage must be inferred from the save semantics and sibling names.

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