completion-script-generator vs j-rig

Two Dev Tools Claude Code skills, side by side. Pick the right skill for your workflow with a side-by-side look at metadata, sample code, and install commands.

Side-by-side

Tag overlap

Sample code from each SKILL.md

# Extract commands and options from commander program
grep -rn '\.command(' src/cli.ts | while read -r line; do
  cmd=$(echo "$line" | grep -oP "\.command\(['\"]([^'\"]+)" | sed "s/.*['\"]//")
  echo "COMMAND: $cmd"
done

grep -rn '\.option(' src/cli.ts | while read -r line; do
  flag=$(echo "$line" | grep -oP "\.option\(['\"]([^'\"]+)" | sed "s/.*['\"]//")
  desc=$(echo "$line" | grep -oP "'[^']*'\s*\)" | head -1)
  echo "OPTION: $flag -- $desc"
done

When to choose each

completion-script-generator — Generates shell completion scripts for CLI tools. Parses command structure from help output, commander/yargs configs, or manual specification. Produces completions for bash, zsh, and fish that follow each shell's…

j-rig — Skill Refiner, the eval-guided improvement loop for SKILL.md files. Runs the bootstrap, score, propose, apply, and status cycle as a thin wrapper over the published @intentsolutions/refiner CLI, proposing safe,…

Both are free to install. If you're unsure, install both — Claude Code skills are isolated by filename and only collide if their trigger phrases overlap (rare). The richest signal is the SKILL.md body itself — open both skill pages and read the first paragraph of each.
