Full written post / accessibility read

UHP, draft dated September twelfth twenty twenty six, puts the unit of exchange at a job or task. A product picks a harness, starts work, streams progress, continues via a prior response, cancels, and gets files back. That is a product to harness contract. It is not a model API.

Model APIs give you a turn. UHP shaped surfaces give you a running agent with its own tools and session. Products want a job surface, not only a token stream. That pattern shows up in managed harness APIs and IDE harness plug-in surfaces alike.

JetBrains framing of Agent Client Protocol plus a registry is an IDE plug-in surface for third party harnesses. UHP is how a product drives a harness job. Long term coexistence outcomes are untested. Do not collapse them into one protocol box either.

UHP is still a draft. The thing to watch is a conformance suite across vendors, not marketing interchange claims. Production conformance is a watch item, not a fact I can claim from the draft text alone.

Four-beat scene transcript

1. UHP puts the unit on a job.

UHP, draft dated September twelfth twenty twenty six, puts the unit of exchange at a job or task. A product picks a harness, starts work, streams progress, continues via a prior response, cancels, and gets files back. That is a product to harness contract. It is not a model API.

Visual: Not a model turn. A running harness task.

2. Model APIs give turns. Jobs give sessions.

Model APIs give you a turn. UHP shaped surfaces give you a running agent with its own tools and session. Products want a job surface, not only a token stream. That pattern shows up in managed harness APIs and IDE harness plug-in surfaces alike.

Visual: Do not collapse those interfaces.

3. ACP is adjacent, not identical.

JetBrains framing of Agent Client Protocol plus a registry is an IDE plug-in surface for third party harnesses. UHP is how a product drives a harness job. Long term coexistence outcomes are untested. Do not collapse them into one protocol box either.

Visual: IDE plug-in is not the same as product job drive.

4. Watch conformance, not marketing.

UHP is still a draft. The thing to watch is a conformance suite across vendors, not marketing interchange claims. Production conformance is a watch item, not a fact I can claim from the draft text alone.

Visual: Draft status stays on the label.
