Pawl

Pawl is a set of deterministic checks that block coding agents from making recurring mistakes and damaging systems.

Pawl provides deterministic gates for coding agents to prevent recurring mistakes like dangerous deletions, unauthorized git resets, and infinite loops. It runs as a plugin for Claude Code, OpenAI Codex, and Antigravity, executing small checks as Python code rather than relying on prompt instructions. The software watches for specific errors, refuses unsafe commands, cleans up issues, and approves read-only actions without prompting. It features hook gates and CLIs that handle tasks such as verifying test fixes, tracking baselines, and capping token sizes. Built with the Python standard library, it operates locally with zero telemetry, model calls, or external dependencies.
