backnotprop/pstack
WritingUpdated 3 days ago
From the author
Apply to any non-trivial work, not just bulk work: edits, migrations, analyses, checks. Build the tool that does it or proves it (codemod, script, generator, or a skill your subagents follow) instead of working by hand. The tool is the artifact a reviewer can rerun.
Install
npx skills add backnotprop/pstack --skill principle-build-the-lever -a claude-code
Installs to .claude/skills/principle-build-the-lever/ · Each command fetches the skill straight from GitHub with the open skills CLI.
