Check Tools - Development Environment Validator
Reports which development tools are installed and at what version, grouped by ecosystem. Default behavior reports every tool without failing validation — suited to diverse PaaS/container environments where only a subset of ecosystems is expected to be present.
When to use
- Verifying a container or environment has the tools a task needs
- Troubleshooting a build failure that might be a missing dependency
- Documenting system requirements
- Onboarding: confirming a dev environment is ready
Running it
# Fast check with exit code (0 = all required core tools present)
bash assets/check-tools.sh
# Development tools only
bash assets/environment-diagnostic.sh tools
# System info: hardware, mounts, processes
bash assets/environment-diagnostic.sh system
# Complete diagnostic (tools + system + package inventories), written to a file
bash assets/environment-diagnostic.sh full /path/to/report.txtcheck-tools.sh exits non-zero only when a required core tool (python3,
pip, node, npm, java, gcc, git, curl, awk, grep, gzip, tar, make, sed) is
missing. Every other tool is reported (✅ found / ⚠️ optional and missing) but
does not fail the run.
Required vs. optional, by ecosystem
| Ecosystem | Required | Optional |
|---|---|---|
| Python | python3, pip | python, uv, poetry, black, mypy, pytest, ruff |
| Node.js | node, npm | nvm, yarn, pnpm, eslint, prettier, chromedriver |
| Java | java | mvn, gradle |
| Go | — | go |
| Rust | — | rustc, cargo |
| C/C++ | gcc | clang, cmake, ninja, conan |
| Utilities | git, curl, awk, sed, grep, gzip, tar, make | jq, rg, tmux, yq, vim, nano |
