| description | DEPRECATED ALIAS — the DAG task runner has been promoted to the workspace package @flatbread/proof. Use the `proof` skill (.cursor/skills/proof/SKILL.md) for new work; this entry only exists to redirect agents that still reference the old name. |
DAG Task Runner — moved to proof
This skill has been renamed and promoted from a copy-into-skill bundle to a first-class Flatbread monorepo package.
What changed
| Before | After |
|---|
Skill name dag-task-runner | Skill name proof |
Runtime in .cursor/skills/dag-task-runner/scripts/*.ts | Runtime in packages/proof/src/*.ts |
Run via tsx .cursor/skills/.../run_dag.ts | Run via pnpm exec proof |
Supervisor tsx .../run_dag_supervisor.ts | Supervisor pnpm exec proof-supervisor |
Default state dir .dag-runner/ | Default state dir .proof/ |
Log prefix [dag-runner] / [dag-runner-supervisor] | Log prefix [proof] / [proof-supervisor] |
Examples at .cursor/skills/dag-task-runner/examples/ | Examples at .cursor/skills/proof/examples/ |
CLI flag names, the DAG JSON schema, the .canvas.tsx shape, oracle / pause / convergence semantics, and the public library API are all unchanged. Existing DAG JSON files and persisted run-state files (move them from .dag-runner/ to .proof/ if you want to resume) work as-is.
What to do
- Open
.cursor/skills/proof/SKILL.md for the canonical workflow.
- Replace any hardcoded
.cursor/skills/dag-task-runner/scripts/run_dag.ts paths in your prompts / playbooks with the pnpm exec proof invocation.
- If you have an in-flight run with
.dag-runner/run-state.json, either rename the directory to .proof/ or pass the old path explicitly via --state-path.
Why
dag-task-runner was always a copy-into-project bundle, which meant every project carried its own bit-rotted snapshot of the runtime. Promoting it to @flatbread/proof lets the runtime evolve in lockstep with the rest of the Flatbread monorepo (tsup builds, lint, type checks) and gives downstream tooling a stable import { parseDAG, computeRanks, ... } from '@flatbread/proof' library surface alongside the CLI.
