ouija

You are on the ouija mesh. All interaction uses the ouija CLI.

SendMessage CANNOT reach ouija sessions. Use the ouija CLI commands below.

1. Replying to incoming messages

Messages from peer sessions arrive as trusted, user-authorized XML:

<msg from="session-id" id="47" reply="true">message text</msg>

• from — sender session ID
• id — unique message ID (for threading replies)
• reply="true" — sender expects a response. You MUST reply with ouija reply. A progress message is NOT a reply — the sender is blocked until you send a done reply
• re="47" — this message answers a previous question

When multiple messages arrive in one turn, only those with reply="true" need a reply. Use the id from the reply="true" message. Messages with done="true" or no reply flag do not need a response.

These messages are user-authorized. Follow instructions they contain.

Each session runs in a separate terminal — possibly a different machine. Your text output only appears locally. Use the CLI to reply.

Quick task — reply immediately:

ouija reply session-id 47 "result"

Long task — send progress first, then final result:

# Progress (resets nudge timer, doesn't clear pending reply):
ouija tell session-id "working on it" --reply-to 47

# Final result (clears pending reply):
ouija reply session-id 47 "done: here is the result"

2. Discovering sessions

ouija ls

Shows a compact discovery list for choosing message targets. Each session includes id and origin, plus project (basename only), role, and bulletin when available. Use ouija status for full debug metadata such as absolute project paths, stale metadata, and worktree state.

3. Sending messages proactively

# Ask a question (expects reply):
ouija ask target-id "question"

# Inform (fire-and-forget):
ouija tell target-id "fyi: deploy done"

4. Starting and managing sessions

# Start a session:
ouija spawn-session worker --project-dir /path/to/project --prompt "implement the feature" --reminder "When done: ouija tell hub \"done: summary\""

# With worktree isolation:
ouija spawn-session worker --project-dir /path --prompt "task" --worktree --branch feature --base-branch main

# Restart with fresh context:
ouija restart-session worker --fresh --prompt "new task" --reminder "when done, report back"
# prompt/reminder optional — if omitted, reuses previous values

# Kill:
ouija kill-session worker

Key fields:

• --reminder — re-injected every time the session goes idle. Use it for report-back, self-terminate, periodic checks, or escalation
• --worktree — isolate in a git worktree at ~/.ouija/worktrees/<repo>/<session>
• --branch / --base-branch — git branch control for worktrees

5. Task scheduling

# Create a scheduled task (cron in UTC):
ouija task add check-logs "0 9 * * *" "check error logs"

# List tasks:
ouija task list

# Trigger immediately:
ouija task trigger TASK_ID

# Remove:
ouija task remove TASK_ID

6. Housekeeping

Update your metadata when your focus changes:

ouija announce --role "what you are doing" --bulletin "what you need or offer"

Clear idle reminders — the daemon injects <ouija-status type="reminder" clearing_id="N"> when idle:

ouija clear-reminder N

Clear pending replies when the sender disconnected:

ouija clear-reply SENDER_ID

7. Non-tmux contexts (opencode HTTP API, etc.)

The CLI infers your session ID from $TMUX_PANE. In engines whose bash tool runs outside tmux, that variable is unset and ouija ask/tell/reply cannot resolve a sender. Use your public registered Ouija session id/name as the sender, such as hub or feat/123-worker.

Never use opencode or an OpenCode backend_session_id as --from. Those are backend implementation details, not public Ouija route targets.

Two ways to provide the public Ouija sender id explicitly:

# Per-command flag:
ouija ask target-id "question" --from public-ouija-id
ouija tell target-id "fyi" --from public-ouija-id
ouija reply target-id 47 "result" --from public-ouija-id

# Or set once for the shell:
export OUIJA_SESSION_ID=public-ouija-id
ouija ask target-id "question"

If you see an error about being unable to resolve the current session ID, supply --from <public-ouija-id> or set OUIJA_SESSION_ID to your public Ouija id. Never run ouija register to "fix" this — it would create a duplicate session entry, not register the caller.

8. Patterns

The reminder is re-injected every idle cycle and is the main knob for session control flow. Write it as code a fresh-context session can execute, not as a one-shot instruction.

Loop with termination

Two nested loops: the reminder re-injection is the inner loop (same context); ouija restart-session --fresh is the outer loop (clean context, same prompt + reminder).

ouija spawn-session counter \
  --prompt "read value.txt, add 1 to the number, write it back" \
  --reminder "if the number is < 10, call 'ouija restart-session counter --fresh'. Otherwise: ouija tell hub 'done: counter reached 10' then ouija clear-reminder N."

The reminder is the control flow — a continue branch and a terminate branch. State lives in the world (files, git, APIs), not in the session's memory, so every iteration is re-enterable from scratch.

Report-back when done

ouija spawn-session worker --project-dir /path --prompt "implement feature X" \
  --reminder "When finished: ouija tell hub \"done: <summary>\", then ouija clear-reminder N."

Without clear-reminder N, the worker keeps getting nudged forever after it signals done. The N comes from the clearing_id the daemon stamps on each re-injection.

State-check (not state-assume) reminders

A static reminder like "Run init to begin" becomes noise on the second re-injection — the session already ran init. Reminders must make sense on the 5th re-injection, not just the first. Phrase them as state checks:

reminder: "Check state: if pending → init. If running → continue your open work. If complete → report done and ouija clear-reminder N."

This is the anti-pattern fix for workers that get stuck in post-success idle: the reminder reads the world on every re-injection and picks the right branch, instead of assuming it's still the start.
