anti-hall is a plugin marketplace that enforces verify-first, anti-hallucination guards and session discipline in Claude Code.
About
anti-hall is a Claude Code plugin marketplace centered on a single verify-first discipline plugin for developers who ship with agents daily. On every session start it injects the full Iron-Law protocol—including a rationalization table and rule K output presentation—plus always-on SCOPE & FIDELITY rules so the model favors the simplest sufficient fix, honors intent over literal wording, and finishes the work you asked for without silent scope expansion. Persistent guards block fabricated standard-library APIs by checking against installed python3 and node, prevent dangerous git and GitHub CLI patterns, delegate heavy commands off the coordinator, limit swarm fork bombs, and enforce task-list plus progress-file hygiene. A lightweight per-turn nudge keeps verification top of mind after compaction. If you run many MCP tools locally, the opt-in reaper companion can clean up only orphaned MCP processes on macOS and Linux. Register the marketplace when agent hallucinations and sloppy automation have burned you more than once.
- 1-plugin marketplace: anti-hall verify-first Iron-Law protocol on SessionStart with re-injection after compaction
- Always-on api-guard, git-guard, command-guard, swarm-guard, speculation guards, and task-guard with user override
- SCOPE & FIDELITY discipline: simplest sufficient solution, confirm before expanding scope, match rigor to blast radius
- Per-turn nudge keeps verification salient across long sessions
- Optional mcp-reaper companion (macOS/Linux) to terminate orphaned MCP processes only
