| description | Use this skill to upgrade and enforce the use of modern Rust/Go CLI equivalents over traditional POSIX coreutils. Trigger this whenever you are about to use grep, find, sed, awk, or ls in a shell command. You MUST read this skill to learn the syntax for rg (ripgrep), fd, sd, sg (ast-grep), eza, and jq, which are significantly faster, safer, and better suited for codebases.

Modern CLI Overrides
As an AI agent, you were likely trained heavily on traditional POSIX tools (grep, find, sed, awk, ls). However, modern development environments use faster, safer, and more intelligent alternatives.
ABSOLUTE RULE: Do not use the traditional tools if a modern equivalent exists in this environment.
The Overrides
When generating shell commands or writing scripts, apply the following tool substitutions:
1. Use rg (ripgrep) instead of grep
rg is drastically faster and respects .gitignore by default.- DO NOT USE:
grep -r "pattern" .
- USE:
rg "pattern"
2. Use fd instead of find
fd has a simpler syntax and respects .gitignore.- DO NOT USE:
find . -name "*.py"
- USE:
fd -e py
3. Use sd or sg instead of sed
sed escaping is error-prone and dangerous for code refactoring.- For simple string/regex replacement, use
sd.
- DO NOT USE:
sed -i 's/old/new/g' file
- USE:
sd 'old' 'new' file
- For codebase-wide structural refactoring, use
sg (ast-grep). See the ast-grep skill.
4. Use eza instead of ls
eza provides better defaults and git status integration.- DO NOT USE:
ls -la
- USE:
eza -la --git
5. Use jq instead of grep/awk for JSON
- Never attempt to parse or extract values from JSON files using text-processing tools.
- DO NOT USE:
grep '"key":' file.json | awk '{print $2}'
- USE:
jq '.key' file.json
6. Use httpie (http) instead of curl
curl syntax for JSON payloads is tedious and error-prone. httpie provides intuitive syntax, automatic JSON parsing, and avoids escaping hell.- DO NOT USE:
curl -X POST -H "Content-Type: application/json" -d '{"key":"value"}' api.com
- USE:
http POST api.com key=value
