OpenClaw v2026.5.18: defineToolPlugin SDK, HTTPS Forward Proxy, Python Debugging Skill
OpenClaw
OpenClaw v2026.5.18 stable (May 18) adds: a new `defineToolPlugin` API plus `openclaw plugins build`, `validate`, and `init` CLI commands for typed simple tool plugins with auto-generated manifest metadata; HTTPS managed forward-proxy endpoint support with scoped `proxy.tls.caFile` CA trust; a Python debugging skill covering pdb, breakpoint(), post-mortem inspection, and debugpy remote attach; modal dialog surfacing in browser snapshots; and over 100 bug fixes. The stable v2026.5.12 consolidated leaner installs by moving WhatsApp, Slack, and Bedrock provider cones out of the core runtime.
Why it matters
The `defineToolPlugin` SDK with CLI scaffolding commands significantly lowers the barrier for building custom plugins — previously required understanding internals; now typed with generated manifests. HTTPS forward proxy support addresses a key enterprise deployment gap.
Importance: 2/5
Stable release: defineToolPlugin SDK for custom plugins, HTTPS forward proxy for enterprise deployments; promoted from v2026.5.16 beta series
