Description
Prevents duplicate subagent sessions running the same task. Saves tokens and reduces lag—no more "multiple Spidermen" doing the same work.
Doppleganger
One task, one agent. Doppleganger stops duplicate subagent sessions from running the same task. That prevents token overspend, UI lag, and the chaos of five identical "task completed" announcements.
Usage
The orchestrator already runs a duplicate check before sessions_spawn (see delegate rule); Doppleganger is the named skill for that behavior. User says: "prevent duplicate agents", "stop dopplegangers", "why are so many agents doing the same thing?" You want a single entry point to check whether a task is already running before spawning. python3 /Users/ghost/.openclaw/workspace/skills/doppleganger/scripts/doppleganger.py check "<task string>" [--json] python3 /Users/ghost/.openclaw/workspace/skills/doppleganger/scripts/doppleganger.py guard --task "<task>" [--json] JSON output: {"duplicate": false, "doppleganger_ok": true} → safe to spawn. {"duplicate": true, "reason": "running", "sessionId": "...", "key": "...", "doppleganger_ok": true} → do not spawn; reply that the task is already running. Exit codes: 0 = no duplicate (or check ok). 1 = error. 2 = duplicate detected.
What it does
check / guard — Given a task string (the same one you would pass to sessions_spawn), returns whether that task is already running. If yes, the orchestrator must not spawn again. Uses the subagent-tracker's check-duplicate under the hood (one source of truth for runs/sessions).
Orchestrator
The delegate rule runs a duplicate check before every sessions_spawn; that check can be implemented by calling Doppleganger (or subagent-tracker check-duplicate) with the router's task string. If duplicate: true, do not call sessions_spawn.
Name
"Doppleganger" = the duplicate agent doing the same thing. One Spiderman is enough.
Category context
Agent frameworks, memory systems, reasoning layers, and model-native orchestration.
