Vowline and Claude Code
Claude Code writes the code.
Vowline proves it works.
Claude Code is Anthropic’s coding agent: you give it a task and it reads and changes your code. Vowline does not replace it: it gives Claude Code its tasks, runs it in a separate worktree, and checks every change on the exact commit before it counts.
| Claude Code | Vowline | |
|---|---|---|
| What it is | A coding agent: it reads your repository and changes code for the task you give it. | A control plane above coding agents: it plans, runs them and proves the result. |
| Where code is written | Where you run it, usually in your working copy. | By the agent of your choice, in a separate git worktree per task. |
| Which models | Claude, Anthropic’s models. | Claude Code, Codex or Cursor, per task or per teammate. |
| What the product promises | Not its job: it works on the task in front of it. | A map of roles, flows and steps, built from the code, with checkable criteria. |
| Proof | Tests run when you or the agent run them. | Approved checks on the exact commit of every change; a promise drops back when its code changes. |
| Team | The sessions you start yourself. | A lead and specialists with areas of the code, chats and a backlog. |
| Deciding | You read what it changed and decide. | You confirm criteria and accept changes; production deploys need your click. |
They work together
Vowline runs Claude Code through its own command line tool and your own login: Vowline never sees your keys. A teammate on Claude Code plans in the chat, takes a task with criteria you confirmed, and works in its own worktree; your branch is untouched until you accept.
Vowline reads what Claude Code reports about your subscription and warns in the chat at 80% and 95% of a window. When it runs out, the lead offers to switch that teammate to Codex or Cursor.
When you need Vowline
When several agents change the same product and you can no longer tell what still works. Vowline answers that question with checks, not with an agent saying “done”.
