Tracking token movements

token_flows

Read-only

Get hourly token-flow history for ONE holder segment over a date range. Use token_recent_flows_summary instead for an on-chain snapshot across ALL wallet categories.

Note: Using holder_segment: smart_money is not a good proxy for an overall market view. Use it only if user explicitly requests it, or to combine it with other non smart money data.

This is a more granular tool than token_recent_flows_summary and provides the TOTAL flows over the entire time frame broken down by segment.

Modes:

onchain_tokens (default): Analyze on-chain tokens by contract address
perps: Analyze Hyperliquid perpetual futures by symbol (chain auto-set to "hyperliquid") — supports native tokens

NOTE: Native tokens (0xeee…, So111…) cannot be queried in onchain_tokens mode. If a native placeholder address is supplied, this tool returns Hyperliquid perpetual-futures flows for that chain's native coin instead (e.g. hyperevm → HYPE, bnb → BNB, base → ETH) and prepends a prominent data-source warning. For native-token wallet-category flows on-chain, use token_recent_flows_summary.

A4.7/5.0

Behavior5/5

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

Annotations already declare readOnly/openWorld/non-destructive, and the description adds non-obvious behavior on top: mode-dependent chain handling (perps auto-sets chain to hyperliquid) and the native-token fallback, where a native placeholder address silently returns Hyperliquid perp flows with a data-source warning. That quirk would otherwise be a genuine surprise to a caller.

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?

Front-loaded with the core scope, then organized under Modes/NOTE headings that are easy to scan. Minor waste: token_recent_flows_summary is referenced three times and the 'more granular ... TOTAL flows over the entire time frame' sentence partly restates the opening and sits in mild tension with 'hourly history'.

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?

An output schema exists, so return values needn't be described, and the single top-level param is a nested request object fully documented in schema. What remains slightly unclear is how the 'hourly' series relates to the 'TOTAL flows over the entire time frame' claim, which an agent may need to resolve empirically.

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?

Schema description coverage is 100%, so baseline is 3; the description earns above that by adding semantics the schema lacks — that perps mode auto-sets the chain, that native placeholder addresses are rejected in onchain_tokens mode, and the smart_money segment caveat. It stops short of explaining the from/to token vocabulary, which stays with the 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?

Opens with a specific verb, resource, scope and granularity: 'Get hourly token-flow history for ONE holder segment over a date range.' It immediately names the sibling it is not (token_recent_flows_summary, which covers ALL wallet categories), so an agent can route without opening either schema.

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

Usage Guidelines5/5

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

Explicit routing rules: use token_recent_flows_summary for an on-chain snapshot across all categories, use this one for one segment over time. It also states a when-not caveat ('smart_money is not a good proxy for an overall market view; use only if explicitly requested') and mode-selection guidance, which is exactly the when/when-not/alternatives bar.

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