Multi-agent swarm orchestration harness

boring-swarm

Self-contained multi-agent swarm orchestration. One binary (bsw), one declarative flow.toml, and default worker prompts.

Swarm Concept

bsw runs a bead-native software factory in tmux.

• Work unit: a bead (br issue) with labels like needs-impl, needs-proof, needs-review.
• Orchestrator: bsw daemon/robot, which assigns beads, enforces transitions, and manages worker lifecycle.
• Workers: dedicated panes per role (implement, proof, review, optional committer, plan-review).
• Source of truth: bead state and comments (STATE ...), plus your local .bsw/flow.toml.

Each worker is single-purpose. A worker does not switch roles.

Actors

• implement: writes code/docs for assigned bead only.
• proof: executes gates and evidence checks; does not implement.
• review: validates correctness/scope against bead acceptance criteria.
• committer (optional): async commit/push worker triggered by configured workflow events.
• plan-review (optional): runs after bead lane is exhausted to close or regenerate follow-up work.

Quality Gates

Default quality model is strict lane progression:

• Gate 1: implementation complete (STATE impl:done) moves bead to proof.
• Gate 2: proof pass/fail (STATE proof:passed|failed) moves bead to review or back to implement.
• Gate 3: review pass/fail (STATE review:passed|failed) closes bead or sends it back to implement.

The gate semantics are encoded in flow.toml transitions/actions, not hardcoded in prompts.

Standard Flow

Default lane:

needs-impl -> needs-proof -> needs-review -> closed

On rejection:

proof failed -> back to needs-impl
review failed -> back to needs-impl

When no active bead work remains, optional plan-review can run and optionally stop daemon per flow policy.

Install

uv tool install boring-swarm

Or with pip/pipx:

pipx install boring-swarm

Quick Start

bsw init
bsw doctor
bsw spawn
bsw robot

• bsw doctor validates deps + local flow/prompt files.
• bsw robot runs hardened hybrid scheduling for autonomous operation.

Get Started (With Screenshots)

1) Initialize swarm files in your project

cd /path/to/your-project
bsw init
bsw doctor

This creates:

• .bsw/config.json
• .bsw/flow.toml
• .bsw/prompts/*.md

2) Spawn tmux worker panes

bsw spawn
bsw sessions

This starts role-specific panes (implement, proof, review, committer, plan-review) and applies profile colors.

3) Start autonomous orchestration (robot mode)

bsw robot

robot runs hybrid scheduling with event + fallback ticks. It auto-assigns beads, nudges waiting workers, and can recycle unhealthy panes.

4) Open the TUI dashboard

bsw tui

Use the TUI for:

• system status and queue health
• live pane/session states
• bead lifecycle/timeline view
• tick log inspection

5) Customize workflow behavior

Edit .bsw/flow.toml to change:

• states and transitions
• worker counts per role
• provider/model/effort
• lifecycle policy (max_idle, max_lifetime, max_busy_without_progress)
• role colors (color_bg, color_fg, tmux_bg, tmux_fg)

Dependencies

External — installed separately:

Dep	Role
br	Work item CRUD (beads)
bv	Verification / robot ops
ntm	Tmux session + pane management
agent-mail	Inter-agent messaging (MCP)

Prompt resolution

bsw init materializes local files:

1. .bsw/flow.toml
2. .bsw/prompts/*.md

After init, runtime reads only local .bsw/* files. Users can fully overwrite flow.toml.

Flow DSL

• Full DSL reference: docs/FLOW_DSL.md
• Default example: defaults/flow.toml

Build wheels locally

Requires Go 1.24+ and go-to-wheel:

pip install go-to-wheel
go-to-wheel cli/bsw --name boring-swarm --version 0.1.0 --entry-point bsw

Wheels are built automatically on GitHub release via CI.
