The merge gate for AI-written code, with signed, replayable attestation.

Wrap any AI coding assistant (Claude Code, Codex, Cursor, Gemini CLI) with a governance chain that runs your gates, records what changed, and signs a replayable receipt for every merge.

$ delimit wrap -- claude "fix the flaky test in tests/api.spec.ts"

                       replay → https://delimit.ai/att/att_a05050eb8e13277e

Every wrapped run emits a delimit.attestation.v1 bundle: repo head before/after, changed files, gate results, HMAC-SHA256 signature, and a replay URL. Advisory by default; flip to enforcing when you're ready.

See it in action

Worked examples, real artifacts, every claim verifiable:

• Cross-agent handoff: one artifact, four CLIs: structured session handoff between Claude Code, Codex, Cursor, and Gemini CLI through a single JSON record at ~/.delimit/sessions/. Persistent context across sessions, same artifact across four CLIs.
• cal.com v2 API attestation: full diff, signed verdict, replayable bundle. Runs the same chain you get on day one.

For the schema and signing methodology behind every report, see delimit.ai/methodology/mcp-attestation.

Think and Build

Beyond the merge gate, Delimit orchestrates multi-model deliberation and autonomous builds. delimit think dispatches a strategic question to Claude, Codex, Gemini, and Grok; delimit build activates a background daemon that executes ledger tasks through the gate chain. delimit vault manages local secrets (AES-256).

Works across any configuration, from a single model on a budget to a full panel.

Try it in 2 minutes

npx delimit-cli doctor            # 14 prescriptive checks — tells you exactly what to fix
npx delimit-cli status            # Visual dashboard of your entire governance setup
npx delimit-cli simulate          # Dry-run: see what would be blocked before you commit
npx delimit-cli scan              # Instant health grade for your API spec
npx delimit-cli try owner/repo    # Try governance on any GitHub repo

No API keys. No account. No config files.

Pick your first win

Protect my API — catch breaking changes before merge:

npx delimit-cli try
# Creates a sample API, introduces breaking changes, shows what gets blocked.
# Saves a governance report to delimit-report.md

Watch for drift — detect spec changes without review:

npx delimit-cli init        # Sets up governance + drift baseline
# Weekly drift checks run automatically via GitHub Action
