https://unifiedharnessprotocol.dev/ Independent Unified Harness Protocol release, adoption and technical updates. en Sun, 23 Aug 2026 12:00:00 GMT https://unifiedharnessprotocol.dev/uhp-clients/uhp-news-independent-clients-2026-08-23Sun, 23 Aug 2026 18:00:00 GMTmini-ork shipped aaf22c3 adding a uhp provider kind: a stdlib-only direct HTTP transport for UHP 2026-08-11 (/v1/responses, SSE, bearer auth, previous_response_id sidecar), self-described as B1 of UHP adoption with follow-ups pending. SuperQode remains a verified independent UHP client. Both are classified as client implementations only - not servers, not conformance results, not cross-server interoperability proof. New evidence page: /uhp-clients/; new comparison: /uhp-vs-acp/. https://unifiedharnessprotocol.dev/news/uhp-news-v0.8.2-v0.8.3-superqode-2026-08-23Sun, 23 Aug 2026 12:00:00 GMTVerified tags: v0.8.2 adds a self-host session write-wall (per-session UID/workspace isolation, scratch mode 1733), Hermes vision routing, and a commit-documented Full-class 52/52 UHP run; v0.8.3 fixes self-hosted share links without weakening share-token scoping. SuperQode is verified as an independent third-party UHP client (UHPClient, UHPHarnessProtocolAdapter, superqode connect uhp; targets 2026-08-11) — client adoption, not an independent server or conformance result. Unreleased main: Claude Code plugin --plugin-dir and stdio MCP support. Correction: the suite revision 2026.8.11.post1 and relay/envelope/dsh fixes ship with v0.8.1 (an earlier note called them unreleased). Protocol remains 2026-08-11; suite remains post1 with 52 checks. https://unifiedharnessprotocol.dev/news/uhp-news-main-hardening-2026-08-22Sat, 22 Aug 2026 12:00:00 GMTSuite revision 2026.8.11.post1 makes conformance reports honest: a skip is never a pass (conformant vs conformant_with_skips, skipped_not_verified, suite_version, generated_at); 52 checks unchanged. HarnessRouter tagged v0.8.1 on 21 Aug (server-side workspace registry). Unreleased main fixes: failed Response error envelope now spec-valid, Hermes relay normalization (documented patched 52/52 runs), dsh reasoning_effort handling (documented LLMTR run 47/52 to 52/52). Protocol remains 2026-08-11; these are implementation developments, not protocol releases; native adoption still not established. https://unifiedharnessprotocol.dev/news/uhp-news-backend-expansion-2026-08-20Fri, 21 Aug 2026 12:00:00 GMTBetween 18 and 20 August, HarnessRouter shipped v0.6.0 (LLMTR provider), v0.7.0 (Pi backend, Full 52/52 UHP conformance through Pi) and v0.8.0 (DeepSeek Harness backend, Full 52/52 through DSH). All are implementation releases; the UHP protocol stays 2026-08-11. New backends are HarnessRouter integrations, not native adoption. https://unifiedharnessprotocol.dev/releases/#v0-5-5uhp-release-v0.5.5-2026-08-18Tue, 18 Aug 2026 12:00:00 GMTReference implementation tag v0.5.5 updates harness-page actions and documentation/site surfaces; UHP protocol remains 2026-08-11. https://unifiedharnessprotocol.dev/uhp-vs-a2a/https://unifiedharnessprotocol.dev/uhp-vs-a2a/Wed, 19 Aug 2026 06:14:00 GMTComparison of UHP harness execution with A2A agent-to-agent communication and collaboration. https://unifiedharnessprotocol.dev/harnessrouter/https://unifiedharnessprotocol.dev/harnessrouter/Wed, 19 Aug 2026 06:14:00 GMTSeparates UHP protocol requirements from HarnessRouter backends, provider routing and starter-kit product features.
