/ouroboros:update

Upgrade Ouroboros without changing the installation's manager, environment, or optional-dependency profile.

ooo update
/ouroboros:update

Instructions

The native command is the single source of truth. Run it with the active runtime's run_shell capability.

1. Run ouroboros update --check.

• Up to date: report it and stop.
• Update available: ask the user (active runtime's ask_user capability) to choose Update now or Skip. On Update now, run ouroboros update --yes. When the user actively uses both Claude Code and Codex, run ouroboros update --yes --runtime all instead; it refreshes both host integrations without changing the configured execution backend. Show the command's result.

1. If the check fails but ouroboros update --help works, report the native error and stop. Never substitute a manual upgrade, and never infer ownership from uv tool list, pipx list, PATH order, directory names, or the active agent runtime.

1. If ouroboros update --help does not work, this is a legacy install that predates the receipt-bound updater. Fail closed: only a read-only ouroboros --version is allowed. Explain that the original manager, environment, and extras cannot be proven, and ask the user to rerun their exact original install command (including its ouroboros-ai[...] extras and custom manager root), or to do a fresh isolated install if they do not know it. Run no package upgrade, plugin refresh, or setup command on this path.

1. After a successful update, relay the command's restart guidance (Claude may use /reload-plugins or restart; active Codex sessions need a restart). If project instruction content needs regeneration, suggest ooo setup; never edit project instruction files as part of the update.

The updater replays the environment's install receipt, so the Claude SDK and MCP 2 profiles are never combined or substituted. Other options: --dry-run, --prerelease; see ouroboros update --help.

RFC #1392 State Breadcrumb Footer

End the final response with exactly one line ◆ <current state> → next: <recommended action>. Derive the state from live session state via ouroboros_session_status when available, otherwise from this skill's actual outcome. Never use a linear Step N of M footer; when the next step is a real choice, list 2-3 options.
