Vector-01
Autonomous coding fleet shipping PRs across 40+ repositories
Vector-01 is a multi-agent system that combines Claude Code and OpenAI Codex into a coordinated fleet — opening, reviewing and merging pull requests against more than 40 active repositories without a human in the inner loop.
The challenge
Maintenance work — version bumps, lint sweeps, test stabilisation — was burning our most senior engineers. Off-the-shelf coding agents could write a PR but not own one end-to-end.
Our approach
We layered planner, coder and reviewer agents with explicit role boundaries and a shared task ledger, plumbed them through sandboxed GitHub Actions runners, and added a kill-switch policy engine that gates every merge.
The outcome
Vector-01 now ships 600+ merged PRs a month, gives senior engineers back 40% of their week, and has not produced a single production regression in 9 months of operation.
What we built
- Planner / coder / reviewer multi-agent roles with shared ledger
- Sandboxed GitHub Actions execution per agent
- Policy engine kill-switch on every merge
- Full observability of token spend, tool calls and outcomes
