# Build Loop

## Tools Required (OMN-8708)

`build-loop` dispatches workers via `Agent()`. Workers run in fresh sessions where dispatch
tools are **deferred** (schema not pre-loaded). Any worker that needs to further dispatch
sub-agents must fetch the schema at session start:

```
ToolSearch(query="select:Agent,SendMessage,TaskCreate,TaskUpdate,TaskGet", max_results=5)
```

Include this as the first instruction in every `Agent()` dispatch prompt emitted by the loop.

**Announce at start:** "I'm using the build-loop skill to start the autonomous build loop."

## Usage

```
/build-loop                         # Single cycle (default)
/build-loop --max-cycles 3          # Run 3 cycles
/build-loop --skip-closeout         # Skip CLOSING_OUT phase
/build-loop --dry-run               # Simulate without side effects
/build-loop --max-tickets 10        # Dispatch up to 10 tickets per fill
/build-loop --mode close_out        # Close-out only (no fill/build)
```

## Execution

### Step 1 — Parse arguments

- `--max-cycles` → max loop iterations (default: 1)
- `--skip-closeout` → skip CLOSING_OUT phase (default: false)
- `--dry-run` → simulate all phases without side effects (default: false)
- `--max-tickets` → tickets dispatched per fill cycle (default: 5)
- `--mode` → build | close_out | full | observe (default: build)

### Step 2 — Run node

Primary path (bus-driven):

```bash
onex run-node node_build_loop_orchestrator \
  --input '{"max_cycles": 1, "skip_closeout": false, "dry_run": false, "max_tickets": 5, "mode": "build"}' \
  --timeout 300
```

Fallback path (local/offline):

```bash
onex node node_build_loop_orchestrator \
  --input <json_file>
```

Where `<json_file>` contains `ModelLoopStartCommand` JSON matching the payload fields above.

On non-zero exit, a `SkillRoutingError` JSON envelope is returned — surface it directly, do not produce prose. Exit 0 = all cycles completed, exit 1 = any cycle failed.

### Step 3 — Render report

From the JSON output display:
- Summary: cycles completed, cycles failed, total tickets dispatched
- Per-cycle summary: phase outcomes, tickets dispatched, errors
- Circuit breaker status (trips after 3 consecutive failures)

## Phases

| Phase | Node | What It Does |
|-------|------|-------------|
| CLOSING_OUT | `node_closeout_effect` | Merge-sweep, quality gates, release readiness |
| VERIFYING | `node_verify_effect` | Dashboard health, runtime health, data flow |
| FILLING | `node_rsd_fill_compute` | Select top-N tickets by RSD score |
| CLASSIFYING | `node_ticket_classify_compute` | Classify tickets by buildability |
| BUILDING | `node_build_dispatch_effect` | Dispatch ticket-pipeline per ticket |
| COMPLETE | reducer | Cycle finished |

## Safety

- Circuit breaker halts after 3 consecutive phase failures
- `--dry-run` simulates all phases without creating PRs, tickets, or merges
- Max cycles default is 1 — increase only for overnight/cron runs
