# 0.1.19 — 2026-03-21

Devcheck config externalization, template guidance, and field-test skill.

## Added

- **`devcheck.config.json`** — Devcheck now reads depcheck ignores, ignore patterns, and outdated allowlist from a project-local JSON config file instead of hardcoded values in `scripts/devcheck.ts`. Consumer template includes a starter config.
- **"What's Next?" section in templates** — `AGENTS.md` and `CLAUDE.md` templates now include a prioritized list of suggested next steps, helping agents guide users through the server development workflow.
- **`field-test` skill reference** — Added to skill tables in `CLAUDE.md`, `templates/AGENTS.md`, and `templates/CLAUDE.md`.
- **`MCP_SESSION_MODE` env var** — Documented in `templates/.env.example` (`stateful` | `stateless`).

## Changed

- **Template Dockerfile** — Simplified production install step; removed manual cleanup of platform-specific `@oven`/`@rollup` binaries (no longer needed).
