The cross-vendor merge gate for AI-written code.

Anthropic checks Anthropic.

Claude, Codex, Gemini, and Grok can review the same PR. Delimit decides the AI-assisted merge and emits a signed, replayable attestation. Humans only see exceptions.

$ npx delimit-cli setup

10 seconds. No API keys. No account. Works immediately.

New in v4.3Gate any AI-assisted CLI
$ delimit wrap -- claude -p "add tests for payments"

Snapshots the diff. Runs lint + tests. Emits a signed, replayable attestation you can point an auditor at.

One Governance Layer. Every AI Model.

Same policies, same audit trail, same enforcement. No matter which assistant writes the code.

~/.delimit/ on disk. Every model reads the same policies, every session.

Live on your schedule, not someone else's

An autonomous loop with a kill switch.

Your AI drafts. You approve. The daemon executes. Every action is typed, whitelisted, and logged — so scheduled work doesn't mean blind work.

01Sense

Workers scan repos, PRs, and deliberation transcripts.

02Draft

A bounded worker produces a typed work order.

03Approve

You click once in the inbox. Audit row written.

04Execute

The daemon runs a whitelisted action — never arbitrary shell.

Why this matters now

Other agent platforms cap scheduled runs at 15 a day. Delimit runs on your infrastructure with your quotas — hourly, every 5 minutes, or only on a governance signal. Pause from the dashboard when you need to, resume when you're ready. The audit trail keeps going either way.

Your AI Writes the Code. Who Governs It?

Models self-verify their outputs. Delimit provides the independent audit trail that proves it.

Enforce Policy Across Sessions

Claude forgets your rules when the session ends. Delimit persists them on disk in ~/.delimit/ -- every model reads the same policies, every time.

Audit What Agents Shipped

Which model deployed that breaking change? Delimit records every action with evidence -- who changed what, when, and which assistant did it.

Chain Security Into Deploys

Lint, semver classification, security audit, deploy gate. Automatic enforcement chain. Every time. No agent can skip a step.

How It Works

1

Define your governance policy

npx delimit-cli setup creates a .delimit/policies.yml with your rules. Choose strict, default, or relaxed -- or write custom policies.

2

AI writes code. Delimit enforces rules.

When any AI assistant modifies your API spec, Delimit auto-chains: diff, semver classification, governance evaluation, security audit, evidence collection. No manual steps.

3

Breaking changes blocked before merge

The GitHub Action catches 27 types of API changes on every PR. Semver classified, migration guide posted, policy violations flagged -- before anyone clicks merge.

4

Full audit trail, always

Every governance decision, every blocked deploy, every security finding -- recorded with evidence. Know which model changed what, and when.
