  Run a verified multi-agent goal with Bernstein. Use when a task is too
  large for a single agent session: Bernstein decomposes the goal into
  tasks, spawns CLI coding agents in parallel git worktrees, verifies
  their output, and merges results. Also use to check run status, costs,
  and to verify a finished run against its lineage and audit chain.

Run a verified multi-agent goal

Bernstein is a deterministic multi-agent orchestrator for CLI coding agents. This skill wraps the three-step operator loop: submit a goal, monitor progress, and verify the finished run against its Merkle-chained lineage journal and HMAC audit chain.

Prerequisites

• `bernstein` on PATH (`pip install bernstein` or `uv tool install bernstein`).
• Run commands from the project root (the directory holding `.sdd/` after

the first run).

• First-time setup: `bernstein init` scaffolds config and templates.

Workflow

1. Submit

bernstein run -g "<goal>"

• The goal is a plain-English description of what to build or fix.
• Bernstein plans tasks, assigns roles (backend, frontend, qa, security,

devops), and spawns agents in isolated git worktrees.

• Preview without spending: `bernstein run --dry-run -g "<goal>"`.

2. Monitor

bernstein status
bernstein cost

• `status` shows task summary and agent health.
• `cost` shows the spend so far against configured budgets.

3. Verify

bernstein lineage verify <run_id>
bernstein audit verify

• `lineage verify` recomputes the run's Merkle hash chain and every HMAC

tag; exit 0 means the chain is intact and non-empty.

• `audit verify` checks the HMAC audit chain and Merkle tree across the

whole workspace; run it before trusting or shipping the result.

Report the run as complete only when both verifications exit 0.

Verifying this skill's own install

Installs of this skill are receipt-backed. To confirm `bernstein` is on PATH and the bundled skill asset resolves in this session:

bernstein skills package show

To prove the skill content the session is driving matches what was installed:

bernstein skills package verify --dest <path-to-this-skill-directory>

Exit 0 means the installed tree's content address matches a receipt anchored in the lineage spine and audit chain. These two commands are the self-check contract the multi-host conformance sweep replays per agent host (`bernstein skills package conformance`).

Notes

• Never mark a goal done from agent output alone; the lineage and audit

verifications are the completion evidence.

• If `bernstein` is not installed, say so and point at the prerequisites

above; do not attempt to reimplement orchestration inline.

• See `references/worked-examples.md` for end-to-end transcripts and

per-host invocation notes.
