pi-pstack

Pi package adapter for Cursor's pstack by Lauren Tan (poteto).

What this package provides

  • All 54 core pstack skills (./skills), including /skill:poteto-mode (23 playbooks), all 24 principle-* skills, /skill:how, /skill:why, /skill:architect, /skill:arena, /skill:swarm, /skill:interrogate, /skill:tdd, /skill:bro, /skill:unslop, /skill:no-comments, /skill:ketchup, /skill:recall, /skill:reflect, /skill:correct, /skill:teach, /skill:sharpen, /skill:in-your-own-words, /skill:figure-it-out, /skill:show-me-your-work, /skill:technical-writing, /skill:typescript-best-practices, /skill:benchmark-checklist, /skill:blast-radius, /skill:create-verification-skill, /skill:maintain-verification-skill, /skill:automate-me, and /skill:setup-pstack.
  • Pi subagent profiles (./agents): poteto-agent and comment-sicko, automatically discovered by pi-subagents via the "subagents": { "agents": ["./agents"] } manifest.
  • Pi harness adapter (docs/harness/pi.md): maps Cursor tools (Task, AskQuestion), subagent parameters (environment: "cloud" -> worktree: true), skills (/deslop -> deslop, control-cli -> interactive-testing, control-ui -> dogfood/macuse), session history (history tool and ~/.pi/agent/sessions/), model routes, and ponytail: / AGENTS.md protections.
  • Automated upstream sync & notifications:
    • .github/workflows/sync-upstream.yml polls cursor/plugins (pstack/) every 6 hours, runs scripts/sync-pstack.mjs + npm run check:compat, and commits updates to main.
    • Pi's built-in interactive startup package checker detects new commits on fitchmultz/pi-pstack and displays the native Package Updates Available banner (pi update --extensions).
    • extensions/index.js also performs a non-blocking, cached (6h TTL) check against cursor/plugins/pstack on interactive startup and provides /pstack-status so upstream commits are surfaced immediately even between scheduled sync runs.

Install

pi install git:github.com/fitchmultz/pi-pstack

Maintenance

npm run sync          # Fetch latest cursor/plugins main and regenerate tree
npm run check:compat  # Validate sync invariants, skill/extension discovery, and pack
