devdisk
devdisk is a single Python file with no dependencies that scans your machine for the space developer tools quietly eat: package caches, node_modules, build output, Rust target dirs, Xcode DerivedData, Gradle, Ollama and Hugging Face models. Strictly read-only: writes a local HTML report and a cleanup script you can inspect. macOS, Linux, Windows. Free, no telemetry.

HOL Guard
HOL Guard is an open-source (Apache-2.0) permission layer between AI coding agents (Claude Code, Codex, Cursor, Gemini CLI) and your machine. Before an agent runs a shell command, reads a secrets file, calls an MCP tool or installs a package, Guard checks your local policy and allows, blocks or asks you. Install: pipx install hol-guard && hol-guard init. Optional paid Guard Cloud for teams. Not a gateway or network firewall.
