CLI Tools Skill

Install, audit, update, and recommend CLI tools across 77 cataloged entries.

Triggers

• Reactive: command not found errors -- auto-resolve
• Proactive: "check environment", "install X", "update tools"
• Advisory: Recommend modern alternatives (grep->rg, find->fd, JSON->jq)

Preferred Modern Tools

Recommend over legacy equivalents. See references/preferred-tools.md for examples.

Legacy	Modern	Legacy	Modern
grep -r	rg	diff	difft
find	fd	time	hyperfine
grep on JSON	jq	cat	bat
sed on YAML	yq	cloc	tokei/scc
awk on CSV	qsv	grep for sec	semgrep
sed on TOML	dasel

Workflows

Missing Tool Resolution

1. Diagnose: which <tool>, command -v <tool>, type -a <tool>
2. Map binary: Check references/binary_to_tool_map.md (rg->ripgrep, ansible->ansible-core, batcat->bat)
3. Install: scripts/install_tool.sh <tool> install
4. Verify: which <tool> + <tool> --version; if still missing: hash -r, check PATH

See references/resolution-workflow.md for full diagnostic steps.

Environment Audit

Run scripts/check_environment.sh audit . and scripts/detect_project_type.sh, then cross-reference with references/project_type_requirements.md for per-type tool lists.

Batch Update

scripts/auto_update.sh (all managers) or scripts/install_tool.sh <tool> update (single).

Troubleshooting

Symptom	Fix
Installed but not found	hash -r or add dir to PATH
No sudo	cargo install, pip install --user, manual binary; on Debian/Ubuntu apt-get download + dpkg -x
Debian bat=batcat, fd=fdfind	Symlink to ~/.local/bin/

See references/troubleshooting.md for Docker fallbacks and permission workarounds.
