Resume Session

/ouroboros:resume-session

Recover in-flight Ouroboros sessions after an unexpected MCP server disconnect.

Claude Code reserves /resume for its built-in session picker. This skill intentionally uses resume-session so it does not shadow that native command.

Usage

Copy code
ooo resume-session
ooo resume-session --all
/ouroboros:resume-session

Trigger keywords: "in-flight Ouroboros sessions", "re-attach", "mcp disconnected", "lost Ouroboros execution"

How It Works

ooo resume-session reads the EventStore directly (no MCP server required) and lists every session that is still in a running or paused state. The command is strictly read-only — it never creates the data directory, never writes schema, and never appends events. Its job is to surface the identifiers you need to re-attach.

• ooo resume-session shows the 20 most recent active sessions.
• ooo resume-session --all shows every active session.

Instructions

When the user invokes this skill:

1. Run the CLI command:

   Copy code
   ouroboros resume
   

   This reads the configured runtime EventStore directly — the MCP server does not need to be running.

2. If sessions are listed, enter the number of the session you want to work with. The command prints both the session_id and the exec_id, along with the available re-attach paths.

3. Pick the right re-attach path:

   • Inspect persisted events (read-only):

     Copy code
     ouroboros status execution <exec_id> --events
     

     Reads the configured EventStore without starting an MCP server.

   • Inspect interactively (read-only monitor):

     Copy code
     ouroboros tui monitor
     

     Launches the TUI and lets you pick the session to inspect.

   • Resume execution (requires the original seed file):

     Copy code
     ouroboros run workflow --orchestrator --resume <session_id> <seed.yaml>
     

Exit codes

Fallback (No sessions found)

If the command reports "No in-flight sessions found", the execution either completed, failed, was cancelled, or the EventStore has never been created. To browse historical sessions interactively, use the TUI monitor:

Copy code
ouroboros tui monitor

Example

Copy code
User: ooo resume-session

┌─────────────────────── In-Flight Sessions ───────────────────────┐
│  #  Session ID          Execution ID        Status    Started    │

└───────────────────────────────────────────────────────────────────┘

Enter number to re-attach (1-1), or 'q' to quit: 1

Next Steps

After you have the identifiers:

• ouroboros tui monitor — launch the TUI and pick the session to inspect
• ouroboros run workflow --orchestrator --resume <session_id> <seed.yaml> — resume execution
• ooo evaluate — evaluate results once the execution completes
• ooo cancel execution <exec_id> — cancel if the session is stuck

RFC #1392 State Breadcrumb Footer

Your final response MUST end with exactly one breadcrumb footer line:

Copy code
◆ <current state> → next: <recommended action>

Derive <current state> from live session state via ouroboros_session_status when that MCP projection is available; otherwise derive it from this skill's actual outcome. Never use a linear Step N of M footer because Ouroboros is an evolutionary loop. When the next action is genuinely a choice, list 2-3 honest options in the next: clause. The breadcrumb line must be the last line of the response.
