Purpose
The site explains UHP for developers, tracks implementation evidence and places the protocol in the wider agent-infrastructure landscape. It links back to primary sources so readers can distinguish normative requirements from interpretation.
Independence
Unified Harness Protocol is initiated and led by HarnessRouter. This site is independently published and does not represent HarnessRouter, OpenAI, Anthropic, Nous Research or other projects named in the guide.
Editorial method
- Prefer primary specifications, repositories and vendor documentation.
- Date fast-changing claims.
- Separate reference-implementation support from native vendor adoption.
- Correct pages when the protocol or evidence changes.
- Avoid presenting inference as a verified fact.
Content status
Initial pages were prepared from public primary sources and verified against the UHP repository state available on 15 August 2026. Readers making production decisions should recheck the current protocol version and conformance suite.
