CoinRithm Agent Trading

Cancel spot order

cancel_spot_order

DestructiveIdempotent

Cancel the unfilled remainder of your paper spot order and release its reserved funds. Requires trade:spot scope; get orderId from list_open_orders. Does not reverse filled trades. Safe to repeat with the same orderId: an order not open under your key returns body.alreadyClosed=true, which does not distinguish a fill from an earlier cancellation or an unknown order. Use get_my_trades to check fills. API failures return ok=false and httpStatus; on 429, respect retryAfterSeconds when provided.

A4.9/5.0

Behavior5/5

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

Goes well beyond the annotations (destructiveHint, idempotentHint) by disclosing that filled trades are not reversed, that repeat calls return body.alreadyClosed=true and that this flag conflates fills, prior cancellations, and unknown orders, plus the error envelope (ok=false, httpStatus) and 429/retryAfterSeconds behavior. This is exactly the kind of consequence and edge-case disclosure the annotations cannot carry.

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?

Five tight sentences, front-loaded with the action and required scope, then idempotency semantics, then error handling. No filler; each sentence carries operational information an agent needs before calling.

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-value documentation is not required, yet the description still covers the ambiguous fields (alreadyClosed) and failure modes (ok=false, httpStatus, retryAfterSeconds). Combined with the annotations and a fully described schema, nothing an agent needs to invoke correctly is missing.

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 coverage is 100% and orderId's description already says it comes from list_open_orders, so the baseline is 3; the description reinforces the source and adds that it is 'your' key-scoped order. It adds little about the optional agentTrace object, which the schema already documents, so it stays just above baseline.

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?

States a specific verb and resource ('Cancel the unfilled remainder of your paper spot order and release its reserved funds'), including the important scope qualifier that only the unfilled remainder is affected. This clearly separates it from siblings like get_my_trades, list_open_orders, and place_spot_order.

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?

Specifies the required scope ('trade:spot'), tells the caller where to obtain the required orderId ('get orderId from list_open_orders'), and routes fill-checking to a named alternative ('Use get_my_trades to check fills'). Explicit when-to-use and when-to-go-elsewhere guidance.

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