Closes#257. Thin manifest + skill doc that activates the existing
builtin_tools/hitl.py primitives as a per-workspace opt-in plugin.
The Python implementation (@requires_approval decorator, pause_task /
resume_task tools, multi-channel notification, RBAC bypass roles) is
already in every runtime image — this plugin is the policy layer that
tells agents *when* to call them.
- plugins/molecule-hitl/plugin.yaml — runtimes: langgraph, claude_code,
deepagents; skills: hitl-gates
- plugins/molecule-hitl/skills/hitl-gates/SKILL.md — documents the 5
classes of action that need a gate (deployment / irreversible FS /
public message / production mutation / cross-workspace destructive),
decorator pattern, pause/resume pattern, config shape, 4 anti-patterns,
5-step test plan
No Python code — all implementation already exists. Install per
workspace via POST /workspaces/:id/plugins.
