# Think-in-Code Skill ## Principle **1 Bash script = N Read calls avoided.** When you'd read 10 files sequentially to extract a summary, you waste tokens loading full contents into context. Instead: 1 shell pipeline returns the compact aggregated result. Heuristic: if your task is "for each file in set, compute/extract X, then aggregate" → write the script. Reserve Read for *targeted inspection* of a specific file you already know matters. ## 5 Runnable Patterns ### 1. File size audit (> 100 lines violations) ```bash find . -type f \( -name "*.ts" -o -name "*.tsx" -o -name "*.py" -o -name "*.php" \) \ -not -path "*/node_modules/*" -not -path "*/vendor/*" \ | xargs wc -l 2>/dev/null \ | awk '$1 > 100 && $2 != "total" {print $1, $2}' \ | sort -rn | head -20 ``` ### 2. Multi-grep symbols (compact JSON) ```bash rg --json -g '*.ts' -g '*.tsx' 'export (function|class|const) (\w+)' src/ \ | jq -r 'select(.type=="match") | "\(.data.path.text):\(.data.line_number) \(.data.lines.text)"' \ | head -50 ``` ### 3. Dependencies with versions ```bash # Node jq -r '.dependencies, .devDependencies | to_entries[] | "\(.key)@\(.value)"' package.json 2>/dev/null # PHP jq -r '.require, ."require-dev" | to_entries[] | "\(.key)@\(.value)"' composer.json 2>/dev/null ``` ### 4. Error log scan ```bash grep -rEn 'ERROR|FATAL|Exception|panic:|stack trace' \ --include="*.log" logs/ 2>/dev/null \ | tail -30 ``` ### 5. Lines of code by extension ```bash find . -type f \( -nam...
