Clear, concise description of what this command does in active voice. Never use words like "complex" or "risk" in the description - just describe what it does. For simple commands (git, npm, standard CLI tools), keep it brief (5-10 words): - ls → "List files in current directory" - git status → "Show working tree status" - npm install → "Install package dependencies" For commands that are harder to parse at a glance (piped commands, obscure flags, etc.), add enough context to clarify what it does: - find . -name "*.tmp" -exec rm {} \; → "Find and delete all .tmp files recursively" - git reset --hard origin/main → "Discard all local changes and match remote main" - curl -s url | jq '.data[]' → "Fetch JSON from URL and extract data array elements"
