oh-my-openagent v5.0.0-beta.20

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

Previous name	Beta.20 name	Migration
/start-work and start-work	/ulw-execute and ulw-execute	Hard cutover; no old-name alias.
start-work-continuation	ulw-execute-continuation	Update component paths and hooks.
omo-senpi-start-work-continuation-disabled	omo-senpi-ulw-execute-continuation-disabled	Rename the flag.
skill_loaded: start-work	skill_loaded: ulw-execute	Update telemetry queries.
start_work	ulw_execute	Old key reads for one release with a warning; new key wins.
omo executable	omo-agent-toolkit	Update direct invocations.

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.
