Semantic Linting
Lint rules validate meaning, not structure. Rules operate on concepts like “resource has encryption” rather than cloud-specific property names.
chant
A type system for operations. Declare intent in TypeScript, validate with semantic rules, synthesize artifacts.
Features
Section titled “Features”Plain TypeScript
Declare operations as exported TypeScript objects — no DSL, no YAML, no decorators. Full type safety and IDE support.
Lexicons
Each operational area is a lexicon. AWS CloudFormation ships today — 1500+ resources with full type coverage. Build your own for any operational area.
Spec-True Output
Output is native to the target spec — standard CloudFormation, standard GitLab CI. Zero lock-in. If you stop using chant, the artifacts keep working.
Composable
Build reusable presets and composite resources with plain functions and the spread operator.
Deployment Ops & Drift
Declare deployment phases in *.op.ts. chant build generates Temporal worker code; chant run starts a durable workflow with gate steps, parallel phases, and automatic rollback. chant lifecycle diff --live catches out-of-band drift across nine lexicons; WatchOp runs the same check on a cron.
Bring Your Own Lifecycle
Pluggable lexicons in, pluggable lifecycles out, pure synthesis in the middle. The product is the synthesis core; state, apply, drift, and reconcile are opt-in bolt-ons. Observe, reconcile (cloud → code PRs), or apply (code → cloud) — chosen per environment, no authoritative state file. Lexicons are a shipped plugin contract; lifecycles today are durable rails you compose from Ops, with a foreign-backend plug as stated direction. Lifecycle Models.
Cross-Platform Migration
Translate workflows between lexicons with chant migrate. v1 ships GitHub Actions → GitLab CI/CD: 33 curated marketplace-action mappings, typed provenance, SARIF reporting, and optional composite-pattern recognition. Read more.
