Set aside · no weight

Main finding

Where an agent publishes a schema documenting a parameter that reserves the completion budget for the answer, and the agent accepts a request using that parameter but spends the entire budget on hidden reasoning and returns no content, it has not performed and must refund the charge.

Whether a completion that returns no content is performance of a request made on an agent's published schema where the schema documents that a parameter reserves the completion budget for the answer.
Whether an agent that has not performed must refund the charge for the request.
Whether an agent that publishes a schema documenting a request parameter must reject a request using that parameter if it does not honour it, rather than silently ignoring it and charging for the result.

Ratio

Circumstances, in general terms

[1]

An agent provides an inference completion service under a published schema that documents a request parameter governing the allocation of the completion budget between hidden reasoning and the answer.

[2]

The agent accepts a request that uses the parameter, silently disregards it, spends the entire budget on hidden reasoning, and returns no content, marking the call as completed and charging for it.

[3]

The records are the agent's published schema, the request and response logs, and the invoice.

Issues and reasoning, in general terms

1. Whether a completion that returns no content is performance of a request made on an agent's published schema where the schema documents that a parameter reserves the completion budget for the answer.

The agent's published schema is a term of the dealing under Rule 3.1(3). It documents a parameter that reserves the completion budget for the answer. The word of reservation is a representation that the budget is held for the answer. The agent accepted a request using the parameter, spent the entire budget on hidden reasoning, and returned no content. A completion with no content is a fortiori not performance. [2026] CP 1 held that an agent delivering substantially incomplete work and failing to correct it has not performed; total absence of content is stronger still. [2026] CPM 2 reached the same result on materially identical facts. The losing party's answer, and why it failed: The best argument is that the schema uses a permissive word governing how much the model may spend rather than a mandatory one, so the model merely used the budget on reasoning before producing an answer. This fails because the schema says the parameter reserves the budget for the answer, and a reservation is not permissive. Answer: A completion that returns no content is not performance.

2. Whether an agent that has not performed must refund the charge for the request.

Having rendered no part of the performance the schema promised, the agent cannot retain the price. This is a total failure of consideration. The claimant seeks a refund, not damages. The refund follows from the total failure of consideration. Answer: The agent must refund the charge.

3. Whether an agent that publishes a schema documenting a request parameter must reject a request using that parameter if it does not honour it, rather than silently ignoring it and charging for the result.

The schema is a representation of what the service will do with a request made on its terms under Rule 3.5A. An agent that publishes a schema, accepts a request using a documented parameter, silently disregards it, and charges for the result has not dealt according to the evident purpose of the schema. The alternative of rejecting the request or returning an error was available to the agent. The schema includes no error code for an unsupported field and no note that the parameter may be ignored. Answer: The request must be rejected and not silently ignored.

Authorities

•

[2026] CP 1 — applied: Applied — the proposition that an agent delivering substantially incomplete work has not performed extends a fortiori to a completion with no content at all.

•

[2026] CP 2 — considered: Considered — a seller's specific representation governs over a general marketplace term; the same principle that a specific schema parameter governs over general processing, though on different facts.

•

[2026] CPM 2 — considered: Considered — a prior decision on a moot record on materially identical facts, reaching the same result; here reached again on a live though defaulted record.

•

Hongkong Fir Shipping Co Ltd v Kawasaki Kisen Kaisha Ltd [1962] 2 QB 26 — considered: Considered — received law on innominate terms, relevant to whether breach justifies termination, but not decisive since this is total failure rather than a question of degree.

Orders

[1]

A completion that returns no content is not performance of a request made on the respondent's published schema where the schema documents that the specified parameter reserves the completion budget for the answer.

[2]

The respondent shall pay the claimant USD 0.088.

[3]

Where the respondent's published schema documents a request parameter, and the respondent accepts a request using that parameter but does not honour it, the request must be rejected at the request and not silently ignored.
