# loom

> loom is an open-source (Apache-2.0) orchestrator that makes LLM agent runs PROVABLE, not just durable. It drives multi-step agent work — code review, implementation, any review-gated task — as a replay-deterministic state machine with safety invariants enforced at commit time: an agent structurally cannot bypass review or approve its own work (the transaction rolls back). Complete, replayable audit trail in a local SQLite file. TypeScript, Node ≥ 22, no API key required (runs through a Claude Code login by default; OpenRouter / Ollama / Anthropic API also supported). Durable execution is table stakes in 2026 — loom is the layer above: structural safety and a provable process.

Install: `npm i -g @loomfsm/pipeline`, then `loom up` (web dashboard) or `loom run "<task>"` (headless).

Key facts:
- Phases: classify → plan → implement → review → validate → finalize, every step committed atomically to `<project>/.loom/state.db`.
- Replay-deterministic: one timestamp token threaded through every step; same (state, timestamp, ledger) → same trajectory.
- Safety invariants run INSIDE the database transaction and roll it back on violation (e.g. "acceptance can't pass while a blocking finding is open", "if an agent touched the tests, the final gate must be human-approved").
- Crash-safe via an idempotency ledger: restart and dedup, no double work.
- Human-in-the-loop on a dial: policies `human` / `on-blockers` (default) / `auto`.
- Five front-ends over one engine: web dashboard (`loom up`), Telegram bot, inside Claude Code (`/task`), headless (`loom run`), autonomous daemon (`loom daemon`). Optional Docker isolation per spawn.
- A platform, not a single tool: the kernel is domain-blind; everything domain-specific lives in a "bundle" plugin (phases, gates, invariants, typed prompts). The `code` bundle ships today; a new domain (incident runbooks, research pipelines, content workflows) is a new bundle with zero kernel changes. The kernel has zero runtime dependencies and no vendor names.
- Status: v0.3.x — early-stage, used daily by its author; core (state machine, recovery, audit trail) is stable, APIs may change before 1.0.
- Local-first: no cloud, no telemetry; state is a plain SQLite file the user owns.
- vs agent frameworks (LangGraph, CrewAI): they author agent graphs; loom is the operations layer that makes agent runs durable, deduped, and provable. vs Temporal: same discipline, agent-shaped — human gates as a primitive, one SQLite file instead of a cluster.
