proxysoul/soulstack
ProxySoul's agent stack: design, testing, marketing and performance skills, immune cells and working takeaways as rules.
Make an Electron or web app measurably faster without losing a feature, and prove it. The agent builds a repeatable A/B harness that drives the real production build through Playwright and reads Chromium's own counters over the DevTools protocol, finds the cause of the cost with a Blink style-invalidation trace and a React commit probe instead of guessing, fixes root causes, re-measures the same way, and writes a self-contained HTML report that shows the regressions as loudly as the wins. Use when the user asks to profile, speed up, slim down, find memory leaks in, or benchmark before and after on a desktop or web app, or asks for a performance report.
Build a product's design system and redesign its website (or any product UI) from scratch into a distinctive, alive, theme-aware site that is grounded in what the product really is. The agent first studies the codebase and the owner's way of talking to find the product's concept and vibe, then plans a design system of connected variants (palette, logos, screenshots) on one spacing scale, builds every page with parallel sub-agents, captures real product imagery, verifies by looking at screenshots at phone, laptop and ultra-wide widths in every theme and mode, and finishes by writing a design_system/ folder so the next agent can continue without context. Use when the user asks to redesign, rebuild or "bring to life" a product website, landing page or docs site, or asks for a design system handoff.
Build and run an immune system that proves a product works through its real front doors (CLI, terminal UI, desktop app, web, API) on every platform it ships to, finds what is missing as well as what is broken, and turns every confirmed bug into a permanent check. At scale it runs a bug machine, hundreds of agents that hunt, reproduce, review, fix and guard bugs through a state machine of plain files. Use when a project needs testing beyond unit tests, before a release, after a burst of agent-written code, when a bug keeps coming back, or when the user asks for specialized immune cells or a bug hunt.
Build an evidence-backed marketing system from product code and authorized analytics, covering positioning, discovery, launches, conversion, and retention. Use for marketing audits, go-to-market work, measurement reviews, or synchronized reports, slide decks, and videos without inventing results.
