Missing and present guardrails
harn reads public metadata, root files, docs, workflow paths, and common Claude Code harness files.
Add ?repo=owner/name to this URL, or paste a repo above.
Paste any public GitHub or GitLab repository to generate a shareable harn.app score page for Control, Agency, and Runtime readiness.
Add ?repo=owner/name to this URL, or paste a repo above.
Each repo page has stable, crawlable copy about the repository's agent-readiness profile, common failure modes, and next install step.
Does the repo tell an AI coding agent what good work means? We look for AGENTS.md, CLAUDE.md, static sensors, tests, and architecture constraints.
Does the repo bound what the model can do? We look for Claude settings, MCP/tool declarations, delegation patterns, and explicit permission boundaries.
Does the repo mechanically catch broken behavior? We look for lifecycle hooks, CI, trace/checkpoint state, and Stop-hook loop prevention.
