Uninstalled Orca left zombie hooks slowing 11 coding agents; Multica audited clean

While debugging Antigravity network lag, a user found that Orca — installed and uninstalled long ago — had stuffed sync hooks into the global configs of 11 local coding agents (Antigravity, Codex, Gemini, Qwen, Kimi, OpenCode, etc.) without cleaning up /.orca/agent-hooks on uninstall. Each tool call spawned nested /bin/sh + a cold-started python3 blocking on stdin (5s timeout), serially launching 40 python processes per task.
Jiayuan then audited Multica (screenshot): it never registers hooks in any agent's global config (/.claude, /.codex, /.gemini, etc.), uses per-task overlay config dirs, and its only write — Cursor's hooks.json — lives in daemon-managed task dirs, never overwrites user hooks, is deleted after tasks, and fails open returning {}.
If you ever installed Orca, check /.orca and your agents' hooks.json/settings.json — cleanup noticeably speeds things up.
