Summary

AI summary

Plan-and-Execute architecture formalized, agent identity cards with capability enforcement, and built-in eval framework introduced.

Full changelog

v1.8.4

Planning, identity, and evaluation.

Features

  • Plan-and-Execute architecture formalized. Planning and execution are now explicit phases with typed interfaces, so you can swap planners without touching executors.
  • Agent identity cards with capability enforcement. Every spawn carries a signed identity card; the orchestrator refuses tool calls outside the card's declared capabilities.
  • Built-in eval framework with per-model accuracy reporting — useful for A/B-ing planners, routers, or adapter configs.
  • Canary deployments for prompt/model versions. Route a fraction of traffic to a new prompt or model; promote automatically on metric parity.
  • Opus alias upgraded to Claude Opus 4.7 — default "opus" now resolves to the 4.7 snapshot.

Docs

  • Added growth metrics breakdown.
  • Small README polish.

CI

  • npm publish: NPM_TOKEN is exported so .npmrc interpolation works under GitHub Actions.
