code-yeongyu/oh-my-openagent v5.1.13 on GitHub

MCP tools work again when memory is on. Since 5.1.10, a finished memory child or delegated task shut the shared MCP servers down for the whole process, so every MCP call failed with MCP server <name> is disabled. This release runs on senpi 2026.10.3, which gives each session its own binding to the shared servers; it was verified with the shipped bundle. If you can't update yet, turn memory off until you do: set "memory": { "enabled": false } in ~/.omo/omo.json, or start omo with --omo-senpi-memory-disabled=true.

Fixed

MCP calls no longer fail with MCP server <name> is disabled after a child session ends. A memory child or a delegated task that finished released the MCP service for every session in the process; now it releases only its own binding, and the shared servers stay up. Thanks to @Tygb99 for the report. (#9461, senpi#2524)

Codex edition (LazyCodex): a project's own registered agent roles can be spawned. The spawn guard accepted only LazyCodex's 12 bundled roles, so a role registered in .codex/agents or $CODEX_HOME/agents was refused even though Codex offered it; it now accepts any role with a registered role file and still refuses unregistered ones. Thanks to @aconley-vultr for the report. (lazycodex#171, lazycodex#164, #9462)

Cancelling a delegated task while its host can't list its sessions keeps the cancel pending instead of finishing it with the session still open; it completes once the host answers again. (#9450, #9459)

Skills are listed in a stable order, so the tool prefix of a prompt stays the same between turns and keeps hitting the prompt cache. (#9433)

OpenCode edition fixes, thanks to @cynkai: an explicitly chosen model no longer falls back through the built-in chain (#8808); a plugin-load telemetry failure no longer prints into the TUI (#8804); a background task whose session stopped on an error is finalized (#8814) and skips fallback models no connected provider serves (#8844); Sisyphus stays available when Hephaestus isn't registered (#8841); and omo.schema.json embeds the [opencode] schema once and no longer marks defaulted fields as required (#8871, #8873). Tool argument rewrites in the OpenCode edition also keep the original arguments object (#9466).

omo host status --all and omo thread list no longer show an older session entry as the latest activity when the final JSONL entry is large, partial or invalid. Both surfaces use the same bounded final-record policy, show null when freshness cannot be proved, and list known activity newest-first with unknown activity last. (#9222)

A message to a published terminal session that the engine still reports as not answering is kept offline instead of being sent straight to its socket, so omo thread list, a send and a steer always agree on whether that session can be reached right now; the message is delivered once a later check lists the session live again. A bound send that names its session no longer pays the same lookup twice. (#9222)

Changed

omo runs on senpi 2026.10.3 (the MCP fix above, plus the Bun -e host-launch and WebView readiness fixes). Full list: senpi 2026.10.3.

OpenGateway tasks run without a concurrency limit by default. (#9427)

Added

The session gateway entries below are its store foundation; the thread tools become usable with 5.1.14.

Every session can reach every other one, terminal sessions included. (#9143) Messages between sessions now go through a session gateway: one small database in the agent directory, with no daemon to run and nothing to configure. A terminal session opens a private control socket, so a Desktop thread, a task child or a script can list it, read it and send to it; the thread tools list terminal sessions with their real names and times. A message never interrupts what you are doing: while you are typing, or a submission of yours is on its way, it waits, and the session shows one line saying a remote message is queued. A message to a session that is not running is kept for 24 hours and taken when the session runs again. Fixed limits stop runaway loops: a session cannot message itself or reply straight back into the chain that messaged it, a chain of messages stops after 4 hops or 64 messages, one turn reaches at most 16 sessions, and one sender gets a burst of 8 messages to a session, then one every 5 seconds.

omo thread talks to running sessions from scripts and chat connectors. (#9143) omo thread list|send|read|bind|unbind|rebind|bindings|report|answer|outbox|ack runs the thread tools' operations without an agent session, with --json output that is one JSON value (also on failure) and exit codes a script can branch on: 0 done, 1 refused, 2 usage, 3 nothing answering, 4 unsupported here, 5 internal error. JavaScript can import the same operations from the plugin (runtime/thread-sdk/sdk.js) without spawning omo. It never starts a host. Reference: docs/reference/omo-thread.md.

A session can be bound to a chat thread, and report back through it. (#9143) A binding attaches one session to one external thread (any platform; OmO ships no chat connector itself). Messages from the thread arrive with omo thread send --binding, admitted once per platform event. The session posts milestones, reports, questions and its completion to the binding's outbox with thread_report, and a connector reads them with omo thread outbox and acknowledges them. A question carries a reply token that only an answer through the same binding can use. A completion is written only when you ask for one, and survives a restart. At most one active binding holds a thread; unbinding and rebinding name the revision they expect, and a rebind never extends the binding's lifetime.

A chat connector can say who wrote each message, and how it should land. (#9143) omo thread send --binding takes --author-id and --author-name (and --author-user-id). The session sees the author as quoted fields in the message's provenance header, outside the text, so a message cannot pretend to come from someone else. Each author gets their own rate budget in a busy thread. --mode follow_up lets one message land more gently than its binding allows, and never more strongly. answer takes the same author flags, and the outbox records who answered a question. A connector can watch <agent dir>/gateway/outbox.marker to learn about new outbox rows. The reference now spells out that outbox delivery is at-least-once, and that (binding_id, cursor) is the key to dedupe by.

omo host status --all shows when each terminal session was last active. (#9143) Every terminal (tui) row now carries last_activity_at: the time of the newest entry in its session file, the same time omo thread list shows, or null when it is not known.

omo daemon adopt moves a session from a host into your terminal. (#9143) omo daemon adopt <session> asks the host holding a Desktop thread or a background session to hand it over, then resumes it in the current terminal, in the session's own directory. A session in the middle of a turn is refused unless you pass --interrupt, and input the interrupt took out of its queue becomes your first prompts. A session a Desktop window has open is refused unless you pass --force. omo daemon status now lists terminal sessions as tui rows, and handoff and stop --all leave them alone.

Removed

omo daemon attach and the shared-host opt-in env (OMO_ENABLE_SHARED_HOST) are removed; interactive sessions always run standalone. (#9143) A terminal session no longer joins an engine host; it always runs its own session in its own process, and other sessions reach it through the gateway. OMO_ENABLE_SHARED_HOST no longer changes anything. To continue a session that lives on a host in a terminal, use omo daemon adopt.
