How it works (high-level)
The Mistral Vibe autonomous multi-process pattern compresses sprint-level throughput into a single day by parallelizing independent work streams.
One task equals one isolated git worktree created via git worktree add. Each worktree branches from current origin/main, eliminating race conditions that previously plagued the harness (Q-038 fix via pre-fetched origin).
One worker equals one vibe -p invocation reading a CONTEXT.md brief. The worker executes the full PR lifecycle end-to-end: code implementation, build and test, commit with conventions, push to remote, PR creation via Gitea API, and merge attempt. Multiple workers (typically 2-4) run concurrently in separate worktrees, each working on different files and features.
A dispatch-batch.sh script orchestrates the parallel workers and handles cross-worker dependencies. For the rare gaps — price-cap restrictions, broken tests, or ambiguous requirements — a trainer takeover (~5% of cases, typically within 5 minutes) covers the edge cases without blocking the batch.
See documentation/MISTRAL-AUTONOMOUS-PATTERN.md for the complete pattern specification.
Numbers
- 23 PRs Mistral autonomously merged to main in one calendar day
- 95-100% autonomy per batch; trainer takeover only for Q-058 and Q-062 edge cases
- Wall-clock parallel: ~2 minutes for 2 PRs in a concurrent batch (vs ~3-4 minutes serial)
- Cost: ~$0.50-1.50 per simple PR (documentation, minor changes), ~$2-3 per code-heavy PR (complex logic, multiple files)
Why this matters
The pattern compresses a sprint of work into a single day, shifting the operator role from execution to supervision. ADR-0028 (the passwordless auth migration) was essentially completed in this single session — Phase A (magic-link) fully shipped, Phase B (OIDC) advanced through B.4, with only Phase B.5 (BDD scenarios) remaining.
