Overview
Replaces the spells system with Op — a core composite that declares a Temporal workflow. A new Temporal lexicon bridges chant's build artifacts to Temporal's execution engine. chant run <name> replaces chant spell cast. Worker lifecycle is managed via profiles in chant.config.ts. Deployment reports replace agent briefing prompts.
Prerequisite: chant migrates from Bun to Node.js (unblocks Temporal worker support).
What Op is
Op is a Composite in packages/core that declares a named, phased Temporal workflow. Declared in *.op.ts files anywhere in the project. Discovered and built by chant build alongside other Declarables; the Temporal lexicon serializer emits compiled workflow code to dist/ops/. Running an Op means starting the Temporal workflow.
export default Op({
name: "alb-deploy",
overview: "Build and deploy the ALB multi-service stack",
phases: [
phase("Build", [
activity(build("examples/gitlab-aws-alb-infra")),
], { parallel: true }),
phase("Deploy", [
activity(gitlabPipeline("alb-infra")),
activity(waitForStack("shared-alb")),
]),
],
})Why Temporal
- Durable execution — workflows survive crashes and resume from the current phase
- Signals — unblock gate steps from CLI or MCP (DNS delegation, manual approvals)
- Parallelism — multi-region deployments run phases concurrently
- Retry policies — transient failures in
