lil-pstack

Bun-native Cursor SDK coding agent with built-in pstack.

Every prompt runs under poteto-mode. You do not type /poteto-mode. Skills still route from the user prompt the way they do in Cursor CLI once poteto-mode is active.

Setup

bun install
export CURSOR_API_KEY=...

Run

bun run src/index.ts

Plain prompt mode:

bun run src/index.ts -- "fix the flaky test"

Checks

bun check
bun fmt
bun run test
bun run parity:pstack

parity:pstack compares the vendored plugin to the local Cursor pstack source when present, and checks always-on poteto wiring. parity:pstack:live proves skill-body inject. parity:pstack:live-route proves a plain prompt reads a matched playbook file.

Refresh vendored pstack

bun run sync:pstack

By default this syncs from ~/.cursor/plugins/local/pstack. Override with PSTACK_SOURCE. Soft deps outside the plugin (create-skill, optional cursor-team-kit skills such as deslop / control-cli) stay the same as in Cursor CLI: used when installed on the machine, skipped when absent.
