Admiral Configuration
- Model: Claude Opus 4.6 (
claude-opus-4-6) - Max output tokens: 128,000 (reasoning JSON)
- Context gathered per session: full tmux scrollback + first 50 & last 200 transcript messages
- Safety: 57 dangerous-input patterns blocked (with safe allow-list), confidence thresholds (60% send_input, 80% restart), --confirm default on advance
- Docs:

Status Icons
| Icon | Status | Meaning |
|---|
[~] | thinking | Agent is actively processing |
[>] | running | Agent producing output |
[.] | idle | Agent at prompt, waiting for direction |
[X] | shell (dead agent) | No agent detected in this session |
[Z] | suspended | Agent backgrounded but alive |
[!] | error | Error detected in session output |
[+] | completed | Agent finished its task |
[?] | waiting input | Agent asked a question, awaiting response |
Performance & Architecture
- Sequential VM polling: Session discovery from
azlin list (no SSH). Pane capture via sequential SSH - Cached SSH output: Scout caches Phase 1 tmux captures for Phase 3 reasoning (no double-poll)
- Incremental scout:
--incremental flag skips unchanged sessions using ~/.amplihack/fleet/last_scout.json - Bastion tunnel reuse: Reuses existing SSH tunnels via
get_existing_tunnels() instead of creating new ones - PR URL detection: Uses
gh pr list on remote VM for reliable PR detection from git state - Health metrics in reasoning:
fleet_health.py wired into SessionContext for admiral decisions - Unified status classifier: Single canonical classifier in
_status.py (no dual TUI/CLI divergence) - Modular CLI: Commands split across
_cli_session_ops.py, _cli_scout_advance.py, _cli_formatters.py (each under 400 LOC) - Project grouping: Scout report groups sessions by registered project with open objectives displayed
How to Run
Execute via Bash:
fleet <command> [options]
Presenting Results
After running fleet scout or fleet advance, present the output to the user as:
- Summary table — reformat the CLI output into a clean markdown table with columns: VM | Session | Status | Action | Conf | Summary
- Proposed inputs — for any
send_input decisions, show what the admiral wants to send - Follow-up commands — always end with the actionable next steps from the report:
- fleet advance to send next command to all sessions - fleet advance --confirm to review each before executing - fleet advance --session vm:session to advance one specific session - fleet watch <vm> <session> to inspect specific sessions
