loop_search

Find loops in Waveform's library using filters for tempo, name, and bar length. Narrow results by BPM tolerance, substring, or exact/min/max bars.

Instructions

Search Waveform's loop library. Optional filters: tempo (BPM, with tolerance), name (substring), bars (exact), min_bars, max_bars.

A3.5/5.0
Behavior2/5

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 transparency. It does not mention whether the search is read-only, what side effects occur, or any rate limits or permission requirements.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short and front-loaded with the action, followed by a compact list of filters. No redundant or unnecessary detail.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple, but the description omits what the search returns, such as loop names, metadata, or ordering. It also doesn't mention behavior when no results are found, which is a notable gap given the absence of an output schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has six parameters with no descriptions, so the tool description must compensate. It explains tempo is in BPM with tolerance, name is a substring, bars is exact, and min/max bars are range filters. This adds meaningful semantics, though tempo_tolerance's exact behavior is only implied.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool searches Waveform's loop library, a specific resource. The verb 'search' distinguishes it from other loop-related tools like loop_drop.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to choose this tool over alternatives, such as loop_drop or other search tools. It only lists optional filters without explaining scenarios or preferences.

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