get_signal_history

Read-only
Past signals, for checking whether a kind of signal has worked historically
before acting on a live one.

blockchain: solana, bnb, base, eth or rh
wallet_type: kol, smart or whale (default kol)
days: 7, 30, 90 or "all" (default 30)
mode: cluster, entry or exit. Omit for all modes.
limit: how many signals (default 25)

TDQS

A3.8/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered externally. The description adds only parameter values and defaults, with no extra behavioral context such as result trimming behavior (which the schema mentions) or how history is aggregated.

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

Conciseness4/5

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

The purpose sentence is front-loaded and each parameter line is terse. However, the parameter block largely duplicates the schema, so a few lines do not earn their place independently.

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

Completeness5/5

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

An output schema exists, so return values need not be explained. With the purpose, usage context, and all five parameters covered, an agent has everything needed to invoke it correctly.

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

Parameters3/5

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

Schema description coverage is 100%, so the schema already documents every parameter including valid values and defaults. The description restates the same enum-like values without adding new syntax, constraints, or interpretation beyond the schema.

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

Purpose4/5

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

The opening line states a specific verb+resource: retrieving past signals to check whether a kind of signal has worked historically. It implicitly distinguishes itself from the live get_signals sibling via 'before acting on a live one', though it never names that sibling explicitly.

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?

It gives a clear usage context (validating historical performance before acting on a live signal), which is more than implied. It stops short of naming alternatives or explicit exclusions, so it lands below a 5.

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