## Install

```sh
agentstack add skill-abysscn-oh-my-dag-dag-build
```

Requires the [AgentStack CLI](https://agentstack.voostack.com/docs/cli). Works with Claude Code, Cursor, and any MCP-compatible agent.

## About

# /dag-build — parallel build with a hard oracle

For coding tasks that decompose into independently-buildable pieces **and** have a
deterministic pass/fail command. The conductor plans the DAG, agent leaves edit files
concurrently, the oracle command gates the result; on red, a heal round re-plans with
the failure output injected; a halt-judge kills unproductive loops; node checkpoints
make interrupted runs resumable.

## Usage

```bash
bun run dag-build "" \
  [--cwd ]              # where the build happens
  [--oracle-cmd "bun run typecheck"] # deterministic gate; exit 0 = pass
  [--context ""|--context-file p]  # spec/contract fed to the conductor
  [--test | --test-glob ""]   # run tests as part of the oracle
  [--conductor-model M] [--agent-model M] [--leaf-model M]
  [--agent-thinking off|low|medium|high|xhigh] [--leaf-ponytail]
  [--max-fanout 8] [--heal N]        # heal rounds on red oracle (default 1)
  [--review|--no-review] [--review-gate G2|G3]  # embedded dag-review before finish
  [--resume ]                 # resume from checkpoints
  [--allow-dirty] [--no-judge] [--judge-cap N]
```

Exit code = oracle ∧ judge — safe to chain in CI.

## Discipline

- **No oracle, no dag-build.** If you can't state a deterministic pass command, the
  task isn't ready for parallel dispatch — tighten the contract first.
- Requires a clean git tree by default (`--allow-dirty` to override) so a failed run
  is trivially revertible.
- Small, already-loaded single-file edits are cheaper done directly — dispatch has
  fixed overhead; use this where width pays.
