osc_set_pan

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

With no annotations provided, the description carries full burden for behavioral disclosure. While it clearly indicates this is a write/mutation operation ('Set'), it doesn't address critical behavioral aspects like whether this requires specific permissions, if changes are immediate or reversible, potential side effects, or error conditions. The description provides only basic operational semantics.

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, efficient sentence that front-loads the core action and immediately provides essential context. Every word serves a purpose with zero redundancy or unnecessary elaboration. It's optimally concise for this tool's complexity level.

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 mutation tool with no annotations and no output schema, the description provides adequate basic operational information but lacks completeness. It doesn't address what happens after execution (success indicators, error responses), doesn't mention system state implications, and omits any behavioral constraints or side effects that would be important for safe agent operation.

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 schema already fully documents both parameters. The description adds meaningful context by explaining the semantic meaning of pan values (-1.0=left, 0.0=center, 1.0=right), which goes beyond the schema's numeric range constraints. This provides valuable interpretation guidance for the agent.

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 specific action ('Set the pan position') and target resource ('for a channel'), distinguishing it from sibling tools like osc_set_aux_pan or osc_set_bus_pan that target different resources. It provides precise operational context with the numeric range explanation.

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 implies usage context through the parameter explanation (panning a channel), but doesn't explicitly state when to use this tool versus alternatives like osc_set_main_pan or osc_set_bus_pan. No guidance is provided about prerequisites, timing, or exclusion scenarios.

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