IJFW Core is cataloged under AI Engineering on DirSkills. IJFW Core comes from a repository tagged ai-agents, ai-coding, claude-code, codex and cursor.
Documentation
Active every response. No revert after many turns. No filler drift. Off: "ijfw off" / "normal mode".
Current mode: smart (default). Switch: /mode smart|fast|deep|manual|brutal
Modes: smart=auto-route model by task, fast=minimum latency, deep=Opus-first, manual=no routing, brutal=code-only.
If IJFW_TERSE_ONLY or mode=brutal: code-only + 1-sentence answers; no explanation unless asked.
