v0.1.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It does disclose two behavioral traits: the operation is read-only ('Read') and runs without a GUI. However, it does not mention permissions, error behavior, or whether the operation is blocking. These traits are useful but incomplete for a tool with zero annotation coverage.
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 front-loads the primary function. It avoids unnecessary detail and is easy to parse. However, it is so brief that it sacrifices essential context, which is a structural trade-off rather than an efficiency gain.
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 one parameter and no output schema, the description should explain what project_id refers to and what kind of result is returned. It does neither. The agent knows what is read but not how to invoke it correctly or what to expect, making the description incomplete.
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 schema has no property descriptions and the description does not mention project_id at all. An agent receives no explanation of what project_id represents, its format, or why it is required. With 0% schema description coverage, the description fails to compensate, leaving the parameter entirely opaque.
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 a specific verb ('Read') and resource (track strips, sends, FX returns, master chain), which makes the tool's purpose unambiguous. It does not explicitly name sibling tools, so an agent must infer that it is distinct from other inspection tools like plugin_inspect or midi_inspect, but the resource scope is sufficiently unique.
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 alternatives. It does not mention any context, prerequisites, or exclusions. An agent has no hints about when mixer_inspect is the right choice over other inspection tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
