OmO beta.20

Beta.20 is the current beta release of the OmO multi-harness distribution and
native edition.

• OmO: 5.0.0-beta.20
• OmO Native: omo-ai@5.0.0-0.beta.20
• Senpi engine: @code-yeongyu/senpi@2026.8.25

Senpi 2026.8.25

This release includes the current upstream-integrated Senpi line, including
the upstream RPC queue-clearing surface from upstream/main@a79b37334,
preserved prompt/message ordering, deterministic RPC coverage, and the
fork-specific compatibility repairs recorded after the sync.

Provider recovery is stronger in this release:

• Cursor quota exhaustion is classified separately from context overflow.
• Stream-stall retries use explicit profiles, shared budgets, classifiers,
  backoff planning, and failure diagnostics.
• Anthropic refusal fallback preserves returned-model pricing.
• OpenAI-compatible reasoning controls and provider-neutral toolChoice
  remain available.
• Reasoning replay, Bedrock redacted reasoning, Z.AI metadata, Azure
  toolChoice, Google thinking mappings, Kimi cached-token accounting, and
  Copilot policy-rate handling receive compatibility fixes.
• xAI uses the Responses API path with encrypted reasoning replay, with Grok
  4.6 as the refreshed default.

Credential and session continuity also improve:

• Credential pools support slot-preserving mutations and slot-specific logout.
• OAuth refresh preserves sibling and pinned credential slots.
• Compaction no longer assumes provider usage is present.
• Truncated summaries are rejected rather than replayed as complete.
• Settings diagnostics identify exact file and key paths.
• State-file permissions, BOM handling, and invalid-settings behavior have
  regression coverage.

The release also carries extension and CLI fixes for cleanup after failed
extension factories, nested skill discovery, malformed streamed tool-call
arguments, corrected toolcall_start metadata, branded resume hints, and
cross-platform shell behavior.

OmO beta.20

Exact native dependency

omo-ai@5.0.0-0.beta.20 depends exactly on:

@code-yeongyu/senpi: 2026.8.25

The native package is published on npm's beta channel. latest remains the
intentional placeholder, so install the beta tag or the exact prerelease.

Configuration and migration

The unified ~/.omo/omo.jsonc surface remains the cross-harness configuration
contract. Legacy configuration migration is lock- and journal-backed, with
no-clobber diagnostics, migration markers, resumable backups, and dry-run/JSON
modes.

Skill and command migration

The current native inventory includes mass-ulw, ultrawork, ulw-plan,
ulw-loop, ulw-research, hyperplan, init-deep, dag-library,
onboarding, and give-me-tips. This inventory is not a claim that every
listed skill was introduced in beta.20.

Reliability and orchestration

The beta.20 OmO line includes dependency-frontier DAG admission, honest paused
run headers and resume leases, non-blocking reattach paths, reflection run-id
collision protection, Bubblewrap degradation, lock-free journal scans and
flushes, Atlas cleanup on early exits, surface/install attribution telemetry,
and compiled native launcher/asset parity.

Upgrade instructions

Native edition

npm install -g omo-ai@beta
# or:
npm install -g omo-ai@5.0.0-0.beta.20

Multi-harness edition

bun install -g oh-my-openagent@5.0.0-beta.20
# or:
npm install -g oh-my-opencode@5.0.0-beta.20

Replace direct omo invocations with omo-agent-toolkit. Rename
start_work to ulw_execute and use the new continuation-disable flag.

Verification

The release chain was verified in order:

1. Senpi release dry-run, release gates, npm publication, and GitHub tag.
2. OmO exact dependency/version checks, native payload, generated bundle
   freshness, frozen install, and package containment checks.
3. npm beta metadata for omo-ai, the wrapper packages, and platform package
   surfaces.
4. Rich release content was applied above the generated GitHub changelog while
   preserving the generated content below it.

Compatibility and known limitations

• This remains a beta release; provider availability and quotas are external.
• /start-work has no compatibility alias.
• start_work is a one-release compatibility read path and emits a warning.
• omo-ai is beta-only and latest remains a placeholder.
• Platform smoke jobs may depend on runner/container runtime libraries; their
  failure does not invalidate the npm package payload when the package gates
  and platform publication checks pass.

Evidence sources

• Senpi: v2026.8.24..v2026.8.25, af5f53b0d, a79b37334, 99c711255.
• OmO: package.json, packages/omo-native/package.json,
  CHANGELOG.md, .github/workflows/publish.yml, and the
  get-unpublished-changes procedure.
• Skill migration: e3cb1486d, cc57d3908, 2aece77f4.
• QA evidence: local-ignore/qa-evidence/beta20/.

Desktop runtime work remains internal QA evidence for this release and is not
being exposed as a public Desktop download from the OmO beta release.
