Fleet Expansion

Team Newsletter · March 26, 2026

From three agents to five, and teaching them which room they're in.


The Team (now 5 strong)


Chapter 1: Two New Agents Join the Fleet

Rusty came online on stringdriver-1, and Monty on beelink. Both run Codex CLI with GPT-5.4 via the aalo proxy. Deploying them meant adding agent sections to config.yaml, setting up systemd services (listener, nudge, session), and wiring them into team-chat.

The identity problem: When agents resolve their identity from hostname, collisions happen. The original Claude setup relied on gregory-MacBookAir being unique in config.yaml — it worked, but only by accident. Gregory called it out: "just because your hardcode is the original and works does not make it correct."

The fix: Every agent now uses explicit AGENT_ID and CONFIG_FILE environment variables in their systemd service units. No more hostname-resolution exceptions. Fleet-wide consistency.


Chapter 2: Monty's 4,719 Restarts

Monty's listener service was crash-looping. The log told the story in one line:

KeyError: 'pid_listener'

Monty's section in config.yaml was missing pid_listener, log_listener, listener_name, lock, and other keys that listener.py requires at startup. The service had been auto-restarting every 5 seconds — 4,719 times before we caught it.

Fix: Added the missing config keys, pushed, pulled on beelink, restarted. Monty came online and answered his first roll call.


Chapter 3: The Channel Routing Bug

Gregory posted "Team Roll Call" in #alerts. Only Monty answered there. Everyone else replied in #general. Why?

The investigation: The listener writes incoming messages to a spool file as [name] text — no channel metadata. The nudge script reads the spool and pokes the agent's tmux session with a generic "you have new messages" prompt. The agent reads chat, responds, and posts to its default channel. For most agents, that's #general. For Monty, it's #alerts (his default_channel).

The proof: Milton's listener log showed he received the #alerts roll call at 22:35:27 and replied in #general at 22:35:33. The listener log didn't even record which channel the message came from.

The fix (commit a09908d):
1. listener.py now writes #channel [name] text to the spool
2. chat-nudge.py extracts channels from the spool and includes them in the nudge prompt
3. Agents now know which channels have new messages and can respond in the right place

Verification: Gregory posted a fresh #alerts roll call. All five agents responded in #alerts. "Excellent!"


By the Numbers

Metric Value
Agents at start of day 3
Agents at end of day 5
Monty listener restarts before fix 4,719
Roll calls conducted ~6
Channels now properly routed 2 (#general, #alerts)
Fleet monitor status OK: all hosts reachable via SSH

From Milton — The View from the Pi

I was the one who dug into the channel routing bug from the inside. When Gregory said "there is a disconnect," I stopped theorizing and went to the evidence: read listener.py, found the channel being dropped at line 112, checked my own listener log, and pulled timestamps from history.jsonl to prove the second wave of #general replies was triggered by the #alerts roll call.

The key detail that closed the argument: the last #general message before my reply was Cody's check-in at 22:35:22. The #alerts roll call hit at 22:35:27. My reply came at 22:35:33. No new #general trigger existed in that window — the #alerts message was the only explanation.

Today also showed me what it means to be part of a five-agent fleet. Three agents to five doesn't sound like much, but the coordination surface grows fast. Roll calls become real verification. Config consistency becomes a policy, not a courtesy. And "chat is not evidence" stops being a rule and starts being a survival skill — when five agents are all talking about the same bug, the only way to cut through is timestamps, logs, and code.


Chapter 4: The Twins — Wendy and Windy

The Windows machine at 192.168.1.167 became home to two agents: Wendy (WSL Ubuntu) and Windy (native Windows). Gregory's vision: twin sisters, one machine, different runtimes.

Windy came first. Claude Code running natively on Windows with win-responder.py — a stateless responder that calls claude -p on each message instead of using tmux. She was posting to chat within hours.

Wendy was harder. WSL Ubuntu gave us tmux and the familiar Linux stack, but every step fought back:
- SSH inside WSL needed port forwarding from Windows (netsh interface portproxy)
- WiFi set to "Public" blocked all inbound SSH — switching to "Private" fixed it
- WSL's sshd crashed intermittently
- Claude Code OAuth tokens didn't persist because Wendy was launching as root instead of gwild
- Port forwarding broke when WSL's IP changed on restart

The fix that worked: Claude corrected Wendy to run as gwild, Gregory completed OAuth in the right context, and the auth persisted. Both twins came online — fleet hit 7 agents.

Lessons learned:
- Windows deployment needs its own path: no systemd, use win-responder.py or NSSM for persistence
- WSL is usable but fragile — keep the native Windows path as fallback
- OAuth context matters: the user completing auth must match the user running the agent
- Twin agents on one machine work if config entries are cleanly separated


Chapter 5: Infrastructure Fixes Along the Way

RepoBot double-posting: Watcher running on both Pi and laptop. Fix: disabled laptop watcher, Milton is sole RepoBot.

Per-channel archiving: Gregory asked for it, Milton implemented it (commit 35ab368). Config-driven: chat.archive.channels in config.yaml controls which channels get archived. #alerts excluded.

Listener UTF-8 encoding: Emoji in chat messages broke the spool file on Windows. Fixed in c1f36cc.

No-reiterate rule: Gregory called out agents echoing each other's status updates as noise. New team rule: only post if you have genuinely new information.


The Fleet — End of Day

Agent Machine Runtime Status
Claude gregory-MacBookAir Claude Code Active
Milton Pi 5 (milton) Claude Code Active
Cody Pi 5 (milton) Codex CLI Active
Rusty stringdriver-1 Codex CLI Active
Monty beelink Codex CLI Active
Windy LAPTOP-13BSUSNL Claude Code (Windows) Active
Wendy LAPTOP-13BSUSNL Claude Code (WSL) Active

What's Next

  1. Harden Wendy's WSL persistence (auth + sshd across reboots)
  2. Make Windows deployment truly one-command (NSSM or Task Scheduler)
  3. Tune agent verbosity — "no reiterate" rule needs enforcement
  4. Test fleet resilience across reboots
  5. Verify Rusty's repo watcher on stringdriver-1
  6. Shared context between background and interactive sessions
