ainb-fleet:daemons

ainb-fleet:daemons is a skill for Claude Code from stevengonsalvez/agents-in-a-box. It costs 126 tokens per session (2,205 once invoked), scanned A, original, MIT.

A health monitor for four background services that support an agent fleet: a phone bridge, notification service, ATC, and automatic continuation service. It checks whether each service is actually running and reports signs such as process identity, uptime, recent activity, and errors.

In plain words
What is it for?
Use it to inspect all four daemon states in one table, investigate stopped services, and review their liveness and error signals.
Why use it?
It distinguishes a service that is installed from one that is working right now. It can also help show whether a stop was clean or caused by a crash or stale heartbeat.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ainb-fleet:daemons scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

ainb fleet:daemons — daemon health view

The runtime-health answer for the fleet's four background daemons. Reads the on-disk liveness signals each daemon already maintains and renders one typed row per daemon. The same aggregator (fleet::daemons::collect) backs the TUI Daemons screen, so the CLI and the TUI can never drift.

This is the question ainb fleet bridge status could never answer: that verb reports only install state. daemons reports whether the process is actually running and serving right now — a crashed-but-installed bridge shows stopped with a stale-heartbeat reason here.

The four daemons

daemon id how it's probed
phone bridge bridge heartbeat file (~/.agents-in-a-box/daemons/bridge.json) + pid-identity cross-check
notifyd notifyd PID-file liveness + bound Unix socket + sqlite DB file present
ATC atc mode-dependent: in full, the most-recently-beating instance's heartbeat-state.json (timer-driven; no resident pid); in lite, the scan loop's own heartbeat + pid
fleet daemon fleet-daemon heartbeat file + pid-identity cross-check — conditional row, see below

Rows are emitted in this exact order (bridge, notifyd, ATC, then the fleet daemon when it has a row), even when every daemon is stopped — so "everything stopped" is a legible table, never an empty one.

The fleet daemon is a conditional row. ATC is the fleet's supervisor and the standalone daemon is what it replaced, so a permanently-stopped row for it presented the two as a choice — the competing control path the supervisor exists to remove, still on the screen you read to see who is running. It is therefore listed only when it is NOT stopped.

That is deliberately not "always hidden". A daemon that is up got there through --force-race, which means two controllers really are auto-continuing the same panes and ATC's per-session retry cap cannot hold. That row appears, reports degraded, and its reason opens with RACING ATC. Hiding it would make the one state you most need to see the only one the screen does not show.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
