Quickstart

Install the CLI

npx delimit-cli setup

This creates a .delimit/ directory with default policies and detects your OpenAPI specs automatically.

Lint your spec for breaking changes

npx delimit-cli lint api/openapi.yaml

Compares the current spec against its last known version. Reports breaking changes with severity and migration guidance.

Diff two spec versions

npx delimit-cli diff old.yaml new.yaml

Pure structural diff. Lists every addition, removal, and modification across endpoints, schemas, and parameters.

Gate any AI-assisted CLI with a signed attestation

delimit wrap -- claude -p "add tests for payments"

Works with any AI-assisted CLI — claude, cursor, aider, codex, gemini, or any piped producer. Wrap snapshots the git diff before and after, runs lint plus tests, and emits a signed replayable attestation you can hand to an auditor or pipe into CI.

Need to block CI on policy violations? Add --enforce. Need a kill switch on a runaway invocation? Add --max-time 60 and the wrap SIGKILLs the wrapped command after 60 seconds, emits a liability_incident attestation, and prints a cross-model handoff command.

Render a public trust page from accumulated attestations

delimit trust-page -o ./trust && delimit ai-sbom -o ./ai-sbom.json

After a handful of wraps, render them all into a public trust page (static HTML plus JSON Feed 1.1, no framework, offline-renderable) plus a CycloneDX 1.6 bill of materials with AI-specific fields. Deploy the output anywhere. Hand the SBOM to enterprise procurement.
