recompute_exchange_fee_tier_invoice

Read-onlyIdempotent

Exchange Access-Fee / Maker-Taker Tier Recompute: OpenChainGraph compute node (compliance_control). Deterministic OpenChainGraph compute node. By default (compute:"auto") inputs are computed server-side on Cloudflare Workers for gpu:false nodes with a registered kernel; compute:"browser" forces client-side execution and returns a browser delegation URL instead. gpu:true nodes always delegate to the browser. Inputs are processed transiently to compute the response and are not stored, logged, or retained. Use synthetic or anonymised inputs only. Exports an AP2 artifact with execution_hash for chain provenance.

Input Schema

TableJSON Schema

Name	Required	Description
`compute`	No	Compute mode (v0.4 Compute Binding). "auto" (default) = server for gpu:false nodes with registered kernels; "server" = force server-side; "browser" = always return browser delegation URL. gpu:true nodes always delegate.
`parent_hashes`	No	execution_hash values from upstream ChainGraph AP2 artifacts to chain from (sets chain.parent_hashes in the export).
`parent_tool_ids`	No	tool_id values matching parent_hashes, in the same order.
`policy_parameters`	No	Input parameters for this tool's decision function. For gpu:false nodes with a registered kernel, these are computed server-side when compute is "auto" or "server". See the tool's manifest for field names.

A3.5/5.0

Behavior4/5

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

Annotations already declare readOnly/idempotent/non-destructive, and the description adds real behavioral context beyond them: deterministic execution, transient non-stored processing, synthetic-input requirement, and an exported AP2 artifact with execution_hash for provenance. This is meaningfully more than the annotations provide.

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

Conciseness3/5

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

The core purpose is front-loaded, but the body is cluttered with the OpenChainGraph boilerplate, a long FV-status URL and hash, and a snapshot disclaimer that do not help an agent invoke the tool. Every sentence is not fully earning its place.

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?

With no output schema, the description correctly points to describe_tool and covers compute delegation and provenance. But the key decision-input (policy_parameters field names) is left unspecified and usage/exclusion guidance is absent, leaving gaps for a compliance compute node.

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 compute, parent_hashes, parent_tool_ids, and policy_parameters. The description's compute-mode text largely restates the schema, and it defers policy_parameters field names to 'the tool's manifest', adding no syntax detail. Baseline 3 applies.

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 description states a specific verb+resource (recompute Exchange Access-Fee / Maker-Taker tier invoice) and identifies it as an OpenChainGraph compute node in the compliance_control family. It is clearly distinguishable from the sea of sibling compliance tools by domain, though it does not explicitly contrast against any sibling.

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

Usage Guidelines3/5

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

It explains the compute-mode selection (auto/server/browser, gpu:true always delegates) and points to describe_tool for the output schema, which is useful operational guidance. However, it never says when an agent should choose this tool over alternatives or what preconditions (e.g. upstream artifacts) it expects.

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