React core team member open-sources pstack, a skills stack for trustworthy AI coding agents

- poteto (React core team, ex-Meta/Netflix/Cursor) open-sourced pstack, the skills he uses daily to ship quality code with Cursor, arguing the answer to "AI slop" is going deep first, not maximizing throughput.
- His four-layer pyramid for trusting agent output: codebase (strong types, invariants, clear boundaries — make the right thing the easy thing), static analysis (lint, tests, CI, TLA+ — token-efficient early interception), prose (AGENTS.md, skills, used sparingly; he recommends /create-verification-skill), and human review (unscalable at agent speed, so focus it on design review, the highest-leverage point).
- pstack's pitch: once one agent can be trusted to write verifiable code, you get "fearless parallelism" — run multiple agents (poteto-mode) with confidence.
