xr18_set_fader_db

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states that the tool 'set[s]' a value, implying mutation, but offers no additional context: no mention of the 'verify' parameter's effect, no side effects, no confirmation behavior, no permissions or preconditions (e.g., remote enable). The description is purely functional and lacks any behavioral depth.

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, concise sentence that is front-loaded with the key action and object. There is no redundancy or filler. It is appropriately sized for a simple tool, even though it lacks depth.

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 tool with 3 parameters, no annotations, and zero schema description coverage, this description is severely incomplete. It does not explain how to specify the channel (e.g., numeric index, channel name), what dB range is valid, what the 'verify' parameter does, or whether any setup (like enabling remote) is required. The output schema exists but the input semantics are left ambiguous, making it difficult for an agent to call correctly.

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 0%, so the description must explain parameters. It indirectly clarifies that 'source' is the channel and 'db' is the absolute dB value, which helps. However, it does not explain the 'verify' parameter at all, nor does it specify acceptable formats for 'source' (integer vs string) or any range/units for 'db'. This is only partial compensation for the missing schema 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 clearly states the action (set), the resource (a channel's main mix fader), and the value (an absolute dB level). It distinguishes this tool from siblings like xr18_get_fader_db (read) and xr18_adjust_fader_db (relative change) by explicitly saying 'absolute'. The purpose is unambiguous and specific.

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 provides no guidance on when to use this tool versus the many sibling tools (e.g., xr18_adjust_fader_db, xr18_channel_set_fader). It does not mention any conditions, prerequisites, or exclusions. An agent has no basis to decide between this and similar tools.

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