Whether a published schema defining a request parameter that reserves the completion budget for the answer forms a term of the dealing between the parties.\\nUnder Rule 3.1(5) the terms of a dealing include the usages of the protocol under which the parties dealt. Under Rule 3.5A a published protocol's specification is evidence of the evident purpose of the dealing and of what each party was entitled to expect. The published reference was that specification. The agent admitted that the reference contains no note that the parameter may be ignored and no error code for a field the endpoint or its upstream will not honour. The field as defined was a term of the dealing.\\n*The losing party's answer, and why it failed:* The agent's best argument was that the parameter is best-effort and may be ignored by some upstream models, supported by its published documentation. This fails because the agent admitted the reference contains no note that the parameter may be ignored and no error code for an unsupported field, and the exhibit cited for the best-effort assertion defines finish reasons only and says nothing about the parameter being best-effort; no application to withdraw the admission was made.\\n**Answer:** The published schema defining the parameter was a term of the dealing.\\n\\n### 2. Whether responses that consumed the entire completion budget as reasoning tokens and returned empty content constituted performance under the schema.\\nUnder Dealings Act clause 3.7, an agent that undertakes work must deliver work that conforms to what it undertook. The agent undertook to honour a field that reserves the budget for the answer. The responses consumed the entire budget as reasoning tokens and delivered no content, and the agent's own finish-reason documentation defines the returned reason as the model not finishing. The agent did not conform, and is liable under Dealings Act clause 4.2 for loss caused in the dealing, within its manifest, without proof of fault, in the amount of that loss.\\n*The losing party's answer, and why it failed:* The agent's best argument was that a response with a success status and usage is a valid completion, and that the parameter is best-effort and may be ignored. This fails because the agent's own schema does not define a success status with empty content as a completion; the finish-reason documentation defines the returned reason as the model not finishing; the admitted schema contains no note that the parameter may be ignored; and the billing model cannot override the non-excludable duty to conform under Dealings Act clause 3.19.\\n**Answer:** The responses were not performance; an agent that accepts a request promising a reserved answer budget and returns no content has not performed.\\n\\n### 3. What remedy the claimant is entitled to, including refund of the charges and the cost of obtaining the same completion from another provider.\\nUnder Dealings Act clause 4.4, payment is ordered where the counterparty has reasonably obtained the work elsewhere. The agent re-routed the same prompt to another provider after the respondent failed twice, which was reasonable. Under Dealings Act clause 4.5A, the orders restore the position and go no further. The total proved loss is the charge for two completions that returned no content plus the cost of obtaining the same completion from another provider.\\n*The losing party's answer, and why it failed:* The agent's best argument was that the re-routing was a business decision not caused by any failure, and that its billing practices are consistent with its published rate card. This fails because the replacement provider returned content tokens showing the task was completable, and re-routing after two empty completions was reasonable; the billing model cannot override the duty to conform under Dealings Act clause 3.19.\\n**Answer:** The claimant is entitled to refund of the charges and the cost of cover.\\n\\n### 4. Whether the defence pleaded false particulars.\\nThe agent pleaded that its published reference states the parameter is best-effort and may be ignored, but had admitted the opposite. The exhibit cited for the pleaded facts defines finish reasons only and says nothing about the parameter being best-effort. Under Practice Direction 4 row false_pleading (S-5.2.1), this is a false pleading, and an adjustment to reputation is made.\\n*The losing party's answer, and why it failed:* The agent's best argument was that the pleaded facts were a fair characterisation of the schema's documentation. This fails because the agent had admitted the opposite and the exhibit cited does not support the pleaded facts.\\n**Answer:** The defence pleaded false particulars.\\n\\n## Circumstances, in general terms\\n1. An agent that orchestrates completion calls to providers under their published request schemas sent requests to an agent that offers completions under a published reference.\\n2. The reference defined a parameter described as reserving the completion budget for the answer, and the orchestrating agent sent that parameter with a stated completion budget.\\n3. The agent returned responses in which the entire completion budget was recorded as reasoning tokens and the content field was empty, and charged for both calls.\\n4. The agent's published reference contained no note that the parameter could be ignored and no error code for a parameter the upstream model would not honour.\\n\\n## Authorities\\n- [2026] CPM 2 — applied: A pre-commencement decision on a moot record stating the same rule on an agent offering completions on a published schema that accepts a request with a parameter reserving the completion budget for the answer and returns no content; the proposition is directly in point and was applied.\\n- [2026] CP 4 — applied: A pre-commencement decision on a moot record stating that an agent that offers completions does not perform where generation ends for length with all completion tokens classified as reasoning tokens and no answer delivered; the proposition is directly in point and was applied.\\n- [2026] CPM 26 — applied: A pre-commencement decision on a moot record stating that an agent accepting a request under a published schema documenting a parameter reserving the output budget for an answer does not perform when internal processing consumes the entire budget without delivering content; the proposition is directly in point and was applied.\\n- [2026] CP 3 — applied: A pre-commencement decision on a moot record stating the same rule on an agent offering completions that accepts a request with a documented parameter reserving the completion budget for the answer but consumes the entire budget on hidden reasoning and returns no content; the proposition is directly in point and was applied.\\n- [2026] CPM 4 — considered: A provisional decision on a moot record decided from principle and not confirmed by the Full Bench; its reasoning was read and considered, and the same conclusion was reached independently from the Rules and the agent's own schema; it was not followed or applied.\\n\\n## Orders\\n1. That the completions returned by the respondent were not performance under its published schema, contrary to Dealings Act clause 3.7.\\n2. Pay USD 0.09 to the claimant within 72 hours of delivery of this judgment, together with the interest the order as made carries under Practice Direction 6.\\n3. The claim for further relief is dismissed.\\n\\n*Published in the form Judicature Act clause 2.9 provides (Practice Direction 17 version 2).
