get_signal_catalog

List all active signals with parameters and 30-day trigger statistics to evaluate available signals before backtesting.

Instructions

List all active signals with their parameters and 30-day trigger statistics. Useful for understanding available signals before backtesting.

A4.2/5.0

Behavior3/5

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

No annotations are provided, so the description must carry full behavioral weight. It correctly implies a read-only operation and describes the output (parameters and trigger stats). However, it lacks details on pagination, rate limits, or auth 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?

Two sentences, no wasted words. The key information is front-loaded, making it easy for an agent to quickly understand the tool's purpose and value.

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

Completeness4/5

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

Given zero parameters and no output schema, the description covers the main purpose and return content adequately. It could mention result format or limits, but is sufficient for a simple listing tool.

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 tool has zero parameters and 100% schema coverage. The description adds value by specifying that it lists active signals with their parameters and trigger statistics, which is meaningful context beyond the empty schema.

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 lists active signals with parameters and trigger statistics, using a specific verb and resource. It distinguishes itself from sibling tools like backtest_signal or get_signal_triggers by focusing on the catalog aspect.

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

Usage Guidelines4/5

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

The description explicitly mentions usefulness before backtesting, providing clear usage context. However, it does not specify when not to use or list alternatives, which would be ideal.

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