delimit-ai/delimit

**Keep the state. Change the model.**
Keep decisions, records, and handoffs across Claude Code, Codex, Cursor, Antigravity, GitHub Copilot, and Muse. Bring configured models together for hard calls. For code repositories, Delimit also offers a merge gate and local signed attestations.

Every wrapped run emits a local delimit.attestation.v1 bundle: repo head before/after, changed files, gate results, and an HMAC-SHA256 signature. Verify it offline with delimit seal-verify; hosted replay is not available yet. Advisory by default; flip to enforcing when you're ready.

Fastest path to value: delimit check
Zero-config PR safety gate. No init, no setup, no account, no keys — run it on any repo and it applies deterministic checks (breaking API changes + leaked secrets) to your staged or modified files.
When a check finds a breaking change or a leaked secret, it prints the offending file and the issue and exits non-zero — so it drops straight into a pre-commit hook or CI step.
Common options:
--record writes a content-pinned record of the check to .delimit/records/check- .json (or a path you name). That record is the precursor to the signed, replayable Seal attestation — the same evidence shape, pinned to the exact content you checked.

Golden Path — your first 10 minutes
The API check, end to end: lint a spec, see exactly what breaks, classify the bump, settle the hard calls with the model providers you configure, and keep a locally signed receipt of what ran. Then keep the context that survives across sessions and models.
1. Install
scan (delimit_scan) reports what Delimit can do for this repo. init (delimit_init) drops in the policy preset and merge-gate config. No account, no keys.
2. The merge gate, end to end
**Lint the spec change (the gate).** Baseline vs. proposed, with policy applied — one pass/fail verdict.
**See exactly what breaks.** Pure structural diff — added/removed/modified endpoints, schemas, params, no policy.
**Classify the bump.** Deterministic MAJOR/MINOR/PATCH/NONE — same input, same answer, every time.
**Settle the hard calls.** When the gate verdict is a judgment call, put it to multiple models and let them debate to consensus.
delimit setup gives the Codex MCP server a 30-minute tool timeout so a
multi-round panel can return its completed transcript instead of being detached
by the client while its models are still responding.
**Capture the signed, replayable attestation.** After a gate event (deploy / security / test / audit), record the evidence bundle and verify it any time.
Every receipt is offline-verifiable with npx delimit-cli seal-verify . Hosted receipt replay is not available yet.
3. Context that survives sessions and models
Decisions, constraints, and tasks persist across sessions. Continue in Claude Code, Codex, Cursor, Antigravity, GitHub Copilot, or Muse with the saved record.
**Memory** — persist and recall the *why*, not just the diff.
For semantic recall by meaning across sessions, the assistant calls delimit_memory_search (Pro) directly.
