description

Run a declarative GRAPH workflow where AI agents negotiate autonomously — no human gates. A flow is a DOT graph: nodes are agent turns, ensemble reviews, shell verify-steps, or judge/routers; edges carry conditions and loops. Each node dispatches into lope's existing multi-CLI executors (any CLI implements, the ensemble votes). Bounded by per-node and graph-wide visit caps so an unsupervised run can never loop forever. Use when the user wants to shape HOW agents collaborate (fan-out proposers, consensus, fix-loops) as editable, reviewable, version-controlled process — not a fixed linear sprint.

Lope Flow

lope flow runs a declarative graph workflow. Where negotiate/execute/implement are fixed linear pipelines, flow lets you draw the topology — fan out to N proposers, consolidate, implement, fan out reviewers, loop on failure — in a DOT file you edit and version-control. It dispatches every node into lope's existing executors, so there is no new agent runtime: any CLI implements, the ensemble votes.

This is the mode for autonomous, no-human multi-agent runs where you want control over the process shape and a guarantee the run is bounded.

When to use it

• The user wants agents to negotiate what to do autonomously (propose → consolidate → implement → review → loop) without babysitting.
• The user wants to reshape the collaboration (more proposers, a consensus step, an extra fix-loop) by editing a file, not Python.
• The user wants a reviewable, diffable process artifact, or a picture of what the agents will do.

For a one-shot plan use /lope-negotiate; for a fixed linear sprint use /lope-execute or /lope-implement. Reach for flow when the graph shape itself matters.

Node types (each maps to a lope primitive)

type=	What runs	Outcome it routes on
start / exit	entry / terminal (exit may set status="fail")	started / exited
agent	Validator.generate() — the single-writer implementer turn	succeeded / failed
review	EnsemblePool.validate() — the whole team votes (majority)	succeeded / needs_fix / failed
judge	a router: ensemble vote or generate + a structured outcome: block	a label you declare (ok, replan, …)
script	gates.run_gate() — a deterministic shell test/lint step	succeeded / failed
gate	optional human approval pause (omit it for autonomous runs)	succeeded / failed

Edges carry condition="outcome=succeeded" and loop_restart="true" for back-edges. A node's class routes through a cli_stylesheet (.frontier { primary: claude; }) — lope's take on fabro's model stylesheet, routing class → which CLI plays the role.

Bounded autonomy (the safety guarantee)

Every node has max_visits (default 3); the graph has max_node_visits (default max(50, 8*nodes)). Both are enforced before a node runs, so any loop is finite — a non-converging run terminates with a clean escalation, never an infinite loop or unbounded cost. This is what makes "walk away and let it run" safe.

Steps

1. Start from a template (don't hand-write DOT the first time):

   lope flow init consensus        # writes .lope/flow/consensus.dot
   # templates: consensus | judge-loop | review-gate
   

2. Validate it is runnable and bounded (catches dangling edges, dead ends, unbounded loops):

   lope flow validate .lope/flow/consensus.dot
   

3. Render it to see the graph (needs system graphviz; degrades gracefully):

   lope flow render .lope/flow/consensus.dot -o flow.svg
   lope flow render .lope/flow/consensus.dot -T dot     # normalized DOT to stdout
   

4. Dry-run to print the plan without invoking any model:

   lope flow run .lope/flow/consensus.dot --task "<goal>" --dry-run
   

5. Run it — autonomous, bounded, scored, journaled:

   lope flow run .lope/flow/consensus.dot --task "Add a /health endpoint with a test"
   

--out <dir> writes trace.jsonl + report.md; --max-node-visits N overrides the runaway cap; --no-journal skips the Brain entry; pool flags (--validators, --primary, --timeout, --parallel/--sequential) work as in the other modes.

The consensus template (what autonomous looks like)

Start → CheckDoD (judge) → 3 proposers in parallel → Consolidate (join) → Implement → Review (ensemble) → pass:Exit / fail:Postmortem → replan loops back to Implement. No human anywhere. Branch decisions are made by the ensemble vote and judge nodes; the visit caps bound every loop.

Authoring notes

• A judge's single decision selects all out-edges whose condition matches its outcome — that is how one decision fans out to N nodes.
• Mark a fan-in node join="true" so it waits for all its (non-loop) predecessors.
• A script node points at an inline cmd="..." or a named gate in .lope/rules.json (gate="tests").
• prompt="@file.md" loads the prompt from disk.

Do not

• Do not add a human gate node to an "autonomous" flow — it will block waiting for stdin. Autonomous templates have none.
• Do not remove the visit caps to "let it finish" — that is exactly the runaway you are bounding. Raise max_visits deliberately instead.
• Do not wrap lope flow in a script. It is the harness. Edit the .dot, run the CLI.
