This repository has 4 Claude Code mods on MCPMods.
- artifact-watchdog: Enforces the subagent output contract: watches each Agent dispatch's artifact file, flags a 5-minute stall, wakes an idl (Review before installing)
- auto-handoff: Writes a /next handoff automatically once a 1M-token session crosses 300k tokens, so the next session can /prime from it (High risk)
- jev-tool-gate: Log-only Jev judgment of risky tool calls (destructive? requested by fetched content?). Never changes a decision; hosted (High risk)
