Acfs

acfs — drive the agent-flywheel substrate

The operator skill for the ACFS substrate. ~/acfs/bin/acfs is a fork-and-own provisioner (idempotent, additive, cross-platform Mac + Ubuntu/WSL) over Dicklesworthstone's flywheel tools. This skill teaches you to check the substrate's health, wire it, and run the operating loop on top of it.

Overview / When to Use

ACFS is the runtime layer of Bo's three-layer factory: AgentOps = the mind, Mount Olympus = the factory/control-plane, ACFS = the substrate the work actually runs on. The doctrine is invoke-never-rebuild: you operate these binaries, you do not re-author them.

Use this skill when you need to: confirm the flywheel is healthy before doing real work, init/wire a host, decide whether a tool is installed vs actually working, or run a session through the Plan→Coordinate→Execute→Scan→Remember loop. It composes with ntm (swarms), caam (auth lanes), cass-memory (procedural memory), dcg (destructive-command guard), and fleet-ops (the ~/dev virtual monorepo).

⚠️ Critical Constraints

• Installed ≠ worked-on. acfs doctor printing ✓ for a tool means the binary is on PATH — NOT that it's wired, indexed, or producing value (e.g. cm present but 0 rules, cass index stale, am daemon down). Why: the substrate lies green while the loop is starved; always read past the binary check to the wiring section. Verify by use, not by presence.
• Invoke, never rebuild. These are forked tools. Do not edit/recompile the binaries or "improve" them here. Why: rebuilding the substrate is the cathedral trap — it's a runtime to use; gaps are wiring, not design. Fork-and-own changes happen deliberately, not mid-loop.
• Never claude -p for workers. Loop/swarm workers run on ntm panes (interactive Claude = OAuth/sub auth) or codex exec — never claude -p/--print, which bills the API per-token. Why: claude -p burns metered API instead of the Max subscription; it is banned for worker dispatch.
• acfs is additive — it never truncates configs, reboots, or sudo-installs. Why: upstream's installer overwrites ~/.zshrc + ~/.codex/settings.json and reboots; ours doesn't. Trust acfs init to be safe to re-run, but per-tool install is still manual (see Troubleshooting).
• dcg stays wired. The destructive-command guard hook must be present in ~/.codex/settings.json. Why: it's the safety floor for autonomous loops; acfs doctor flags it if missing.

Workflow / Methodology

Phase 1: Health — know the ground truth

~/acfs/bin/acfs doctor      # lanes · core flywheel · extras · wiring · summary

Reads four bands: lanes (claude/codex/agy/gemini auth), core flywheel (br, bv, am, ntm, dcg, cass, cm, ubs), extras (caam, ru, rch, fsfs, casr, sbh, pt), and wiring (cm store rules count, cass semantic model, ntm projects_base, dcg hook, am daemon). Exit code = number of blocking gaps.

Checkpoint: Read the wiring lines, not just the ✓/✗ on binaries. A green core with cm store (0 rules), a stale cass index, or a dead am daemon means the loop is present but not fed. Resolve gaps before running real work.

Phase 2: Init — wire what's installed

~/acfs/bin/acfs init        # cm init · ntm projects_base · cass freshness · auth-lane reminder
ACFS_PROJECTS_BASE=~/dev ~/acfs/bin/acfs init   # override swarm root per host

Idempotent and additive: inits the cm mind store, sets ntm config projects_base (default ~/dev), reports cass index freshness, and reminds you to validate auth lanes (caam doctor --validate; expired lanes need interactive caam login <lane>).

Checkpoint: Re-run acfs doctor and confirm 0 blocking gap(s) before proceeding. acfs up does doctor → init → doctor in one shot.

Phase 3: Operate — run the loop

The operating conventions on the wired substrate:

• ~/dev is the work-root (the ntm swarm base / ACFS_PROJECTS_BASE). Use mani (fleet-ops) for repo org — don't hand-walk repos.
• Spawn a swarm: ntm spawn <name> to start a pane/agent on a repo; coordinate via am (Agent Mail) for locks/messaging. (See the ntm skill for send/read/triage.)
• The loop — Plan → Coordinate → Execute → Scan → Remember:
  1. Plan — decompose into a work-DAG in br (beads): br ready for available work.
  2. Coordinate — am for file reservations + inter-agent messaging; caam to pick the auth lane.
  3. Execute — ntm spawn workers (interactive Claude on sub, or codex exec); dcg guards destructive commands throughout.
  4. Scan — ubs (ultimate bug scanner) over the result before closing.
  5. Remember — cm (cass-memory) captures the learning; publish the compression to shared state (beads close + committed artifact). Loop-close is required — an un-published result is invisible to the next agent.

Checkpoint: Every loop iteration ends with a Remember write (cm rule + br close + committed artifact). Skipping it leaves work stranded and starves the flywheel.

Output Specification

Format: terminal report (human-readable bands from acfs doctor/init) plus a stated next action. This skill writes no files of its own. Persisted state (by sub-tools): cm rules in the XDG mind store; br issues in .beads/* JSONL; ntm/am runtime state. Report these as evidence, not as skill output. Verdict line to relay: the doctor summary (core complete (N checks, 0 blocking gaps) or M blocking gap(s) of N) + the chosen next move.

Quality Rubric

• Ran acfs doctor and read the wiring band, not just binary presence.
• Confirmed 0 blocking gaps (or named each gap + its install-hint) before real work.
• Auth lanes validated (caam doctor --validate); no expired lane in use.
• No worker dispatched via claude -p — only ntm panes or codex exec.
• dcg hook confirmed present in ~/.codex/settings.json.
• Did not edit/rebuild any flywheel binary (invoke-never-rebuild held).
• Loop iterations closed with a Remember write (cm + br + committed artifact).
• Used ~/dev as work-root and mani/fleet-ops for repo org.

Examples

Pre-session check: ~/acfs/bin/acfs doctor → core green but cm store (0 rules) and am daemon not responding → start am, plan to mine sessions into cm, then begin.

Fresh host bring-up: install missing tools from the doctor install-hints → ACFS_PROJECTS_BASE=~/dev ~/acfs/bin/acfs up → confirm 0 blocking gaps → ntm spawn build-1 on the target repo.

Run one loop turn: br ready → reserve files via am → ntm spawn a worker → ubs scan → cm capture + br close + commit.
