Polyphony

Polyphony — Multi-Agent Orchestration

Container-isolated workspaces for parallel agent execution. Each agent gets its own Docker container with a full git clone on its own branch. No conflicts, independent tests, clean PRs.

Architecture (6 Layers)

1. Work Source — Tasks from GitHub Issues (gh api) or local SQLite queue
2. Orchestrator — Supervisor loop: discover -> claim -> route -> provision -> run -> verify -> land
3. Router — Pure function: Task x Policy -> RunSpec (5-dimension complexity scoring)
4. Identity Broker — Resolves named credentials to volume mounts + env overlays
5. Workspace Manager — Per-task git clone --reference, branch checkout, cleanup
6. Worker Runtime — Docker container create/start/stop/logs lifecycle

Task Lifecycle

DISCOVERED -> CLAIMED -> ROUTED -> PROVISIONED -> RUNNING -> VERIFYING -> LANDED
                                                     |           |
                                                     v           v
                                                   FAILED --> BLOCKED
                                                     |
                                                     v
                                                   CLAIMED (retry)

Prerequisites

• Docker or OrbStack installed and running
• At least one agent CLI available (Claude, Codex, or Kimi)
• CLI subscriptions configured (not API keys)

Check:

bashCopy code
command -v docker &>/dev/null || command -v orbctl &>/dev/null

Configuration

All config lives in ~/.polyphony/:

Initialize with: polyphony init

Routing Rules

Rules are evaluated top-down; first match wins. Each rule has a match predicate and an agent target.

yamlCopy code
rules:
  - match: { task_type: docs, risk: low }
    agent: kimi
  - match: { task_type: bugfix }
    agent: codex
  - match: { risk: high }
    agent: claude
default:
  agent: claude
  fallback: [codex, kimi]

Complexity Scoring (5 Dimensions)

Each dimension scores 0-2. Total 0-10.

Routing thresholds:

• 0-3: Delegate to Kimi solo
• 4-6: Kimi + Codex review
• 7-10: Claude direct

Container Isolation

Each task gets:

• Its own Docker container from polyphony-worker:latest
• A full git clone at /workspace (not a worktree)
• Auth volumes mounted read-only (e.g., ~/.claude:/home/worker/.claude:ro)
• Independent test execution
• Its own branch for PRs

CLI Commands

bashCopy code
polyphony init                    # Create ~/.polyphony/ with config templates
polyphony spawn "Fix auth bug"    # Create and route a task
polyphony status                  # Show task states
polyphony cleanup                 # Remove completed workspaces

Integration with Existing Skills

• cross-agent-delegation: Uses Polyphony's complexity scoring for routing decisions
• agent-teams: Uses Polyphony's workspace isolation instead of shared directories
• spawn-team: Uses Polyphony's container provisioning for feature agents
