void_offer

Destructive

Voids a listed offer so it can no longer be committed to. Caller must be the seller assistant. Existing exchanges are unaffected. Returns unsigned transaction data.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
offerIdYesID of the listed offer to void. Caller must be the seller assistant. Existing exchanges are unaffected.
configIdYesBoson/Fermion Protocol deployment identifier. Format: '<env>-<chainId>-<index>' e.g. 'production-137-0' (Polygon mainnet), 'testing-80002-0' (Amoy testnet). Call get_config_ids to list all valid values for this server.
executionModeNo'direct' = standard on-chain tx (sign locally with your wallet → send_signed_transaction). 'metaTx' = gasless relay via Biconomy (send_meta_transaction). Defaults to 'direct'.
signerAddressYesEthereum address that will sign and send this transaction. Must match the wallet that will sign the returned transaction locally.

A4.2/5.0
Behavior4/5

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

Beyond annotations (destructiveHint=true), the description discloses that existing exchanges are unaffected and that it returns unsigned transaction data. This adds valuable context for a destructive operation.

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 concise, consisting of three sentences that cover purpose, prerequisite, effect, and output. No redundant information.

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 the tool's complexity (4 parameters, destructive) and no output schema, the description covers the main aspects: what it does, prerequisites, effects, and return value. However, it does not mention reversibility or behavior if offer is already void.

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 coverage is 100%, and the description does not add new information beyond what is already in the schema. The baseline score of 3 is appropriate.

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 voids a listed offer, differentiating it from siblings like void_non_listed_offer. It specifies the action, resource, and scope.

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 mentions the prerequisite that the caller must be the seller assistant, but does not compare to alternatives or specify when not to use. It provides context but lacks explicit exclusions.

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

A3.7/5.0
Disambiguation4/5

Most tools have distinct purposes with detailed descriptions, but there is overlap among multiple commit_to_* and sign_receive_* variants that could confuse an agent. The tool boundaries are clear for the core workflow, but the sheer number of similar operations slightly reduces clarity.

Naming Consistency4/5

Tool names predominantly follow a verb_noun pattern with underscores (e.g., commit_to_offer, create_seller). Some inconsistency exists with mixed verbs like 'store_', 'sign_', 'send_', but the pattern is largely predictable and readable.

Tool Count3/5

With 63 tools, the server is heavy but covers a complex protocol (offer lifecycle, disputes, metadata, meta-transactions). The count is borderline; some tools (e.g., multiple signing helpers) could be consolidated, but the scope justifies the size.

Completeness4/5

The tool set covers the core protocol flows comprehensively: create, commit, redeem, dispute, resolve, void, and metadata storage. Minor gaps exist (e.g., no dedicated 'get_offer_by_id' but filtering suffices), and meta-transaction support is extensive.
