Review Songspec

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It gives no indication of whether this is a read-only review, whether it persists results, returns feedback, or blocks further workflow steps. The vague 'review boundary' phrase hints at a gate but does not explain its behavior.

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 short and front-loaded, which is good, but the phrase 'Brain review boundary' adds obscurity rather than clarity. It is under-specified rather than elegantly concise.

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?

Despite having an output schema, the tool is part of a larger song workflow and accepts a single complex open object. The description does not explain what input the SongSpec should contain, what 'review' entails, or how this step fits among the sibling tools. An agent would be guessing at the invocation contract.

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?

With 0% schema description coverage and an open object type, the description must compensate by explaining what a SongSpec is or what fields matter, but it only reuses the name 'SongSpec'. The parameter remains effectively opaque to an 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 names a specific action ('review') and resource ('SongSpec'), which is more than a tautology. However, the phrase 'through the Brain review boundary' is unexplained jargon and the description does not clarify how this tool differs from related siblings like generate_songspec or create_project_from_songspec.

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?

There is no guidance about when to use this tool versus alternatives, no workflow context, and no mention of prerequisites or follow-up steps. The single sentence states what it does but not when an agent should select it.

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