set_horizon_level_strength

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

With no annotations provided, the description must disclose behavioral traits. It provides the value range and default, but does not mention side effects, persistence, or required conditions. While not misleading, it lacks depth for a setter without annotation support.

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 description is a single sentence plus a bracketed specification. It is highly concise, front-loads the action and parameter, and contains no redundant information.

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 a simple setter with one parameter and no output schema, the description is adequate: it explains the parameter's purpose, valid range, and default. However, it could be improved by noting that this setting only applies in horizon mode (already stated) and perhaps linking to related parameters like get_horizon_level_strength.

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 single parameter 'value' has schema description 'Value for horizon_level_strength (UINT8, 0–100)'. The description adds the default value (75) and the meaning 'level mode strength at stick center in horizon mode', providing context beyond the schema. Although schema coverage is 100%, the extra information justifies a 4.

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 clearly states the action 'Set horizon_level_strength' and defines it as 'Level mode strength at stick center in horizon mode.' This specifies both the resource and the context, distinguishing it from other set_* tools such as set_horizon_delay_ms or set_horizon_ignore_sticks.

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 is provided on when to use this tool versus alternatives. There is no mention of prerequisites (e.g., requiring horizon mode to be active) or scenarios where adjusting this value is appropriate. The description is purely declarative.

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