ruleprof is an open-source CLI tool that helps AI agent developers analyze and ablate their CLAUDE.md or AGENTS.md rules to see which ones actually change agent behavior and which only increase token usage. It provides actionable insights for optimizing agent configurations and reducing unnecessary costs.
ruleprof sits in PulseGate's LLM eval & observability category. It focuses on determining which agent rules meaningfully impact LLM agent behavior versus those that only increase token costs. It is built as an open-source project for AI agent developers. ruleprof is open source under the MIT license. It runs on the command line.
Behind ruleprof is fernforge, and the product first shipped in 2026. Development happens publicly on GitHub with 7 commits in the last 90 days. PulseGate's similarity index finds few close equivalents — ruleprof occupies a relatively distinct niche. Key capabilities include rule ablation, token usage analysis, and agent behavior profiling.
