set_vbat_hysteresis

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

With no annotations, description carries full burden; it explains the purpose (prevent flicker), unit (×0.01V), range, and default, but doesn't mention persistence or side effects.

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?

Single sentence with parenthetical and bracketed notes; no superfluous words.

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?

Simple one-parameter setter with full schema coverage; description covers purpose, parameter semantics, and use context sufficiently.

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?

Adds significant value beyond schema: explains meaning (hysteresis value), scaling, default value; schema only describes range.

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?

Description clearly states 'Set vbat_hysteresis' (verb+resource) and explains it controls 'Hysteresis on voltage warnings to prevent flicker', distinguishing it from many sibling set_vbat_* 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?

No guidance on when to use or avoid this tool; no mention of prerequisites or alternatives among the many voltage-related siblings.

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