Instructions for lonormaly/builders-stack, covering agents.md — the primer for coding agents, rule zero — worktrees are temporary and share dependencies, 1. the mental model — the buckets, 2. the map — all 17 packages and 3. the laws — do not break these.
Instructions file
Instructions for lonormaly/builders-stack, covering claude.md — the map for coding agents, where things live, conventions (do not break), how to run and adding things.
Agent
The primer now lives at the repo root: ../AGENTS.md — that's the file Codex, Cursor, and Copilot read by convention, so it's the single source of truth.

Scaffold a new shared library under libs/ in the builders-stack monorepo. Use when code is needed in two or more places (apps or services) and should become a single source of truth consumed by package name. Covers the package.json, tsconfig, the one-public-door src/index.ts barrel, and wiring it into a consumer…
Skill Claude CodeCodex
Scaffold a new service under services/ in the builders-stack monorepo. Use when something needs its own URL, port, or independent deploy. Covers the package, entrypoint, config, Tilt, deployment registry, and shared small-image build path.

When the user wants to optimize content for AI search engines, get cited by LLMs, or appear in AI-generated answers. Also use when the user mentions 'AI SEO,' 'AEO,' 'GEO,' 'LLMO,' 'answer engine optimization,' 'generative engine optimization,' 'LLM optimization,' 'AI Overviews,' 'optimize for ChatGPT,' 'optimize for…
Skill Claude CodeCodex
Model a new table (or reshape an existing one) in libs/db with Drizzle — normalize by default, add the right constraints, and index deliberately. Use when adding a table/column, deciding on keys and foreign keys, or when a query is slow because the schema or its indexes are wrong. Enforces the stack's "Drizzle is the…

Diagnose and fix a slow Postgres query in the builders-stack — read its EXPLAIN plan, find the missing index or the ORM N+1, and confirm the fix. Use when a page or endpoint is slow, a query times out, or pgstatstatements shows a hot query. Pairs with design-a-schema for the index itself.

Keep Postgres fast under load and inside Neon's free tier. Use when choosing a connection string, worrying about "the DB crashes at load", deciding a session strategy, or trying to stay under Neon's free limits (storage / compute-hours). Corrects the common mistake of reaching for postgresql.conf / PgTune — most of…

Add or swap a payment provider behind the @stack/payment adapter in the builders-stack monorepo. Use when integrating Stripe, Paddle, Lemon Squeezy, or any provider alongside or in place of the default Creem adapter. The whole point is that apps and the API never change — only the adapter implementation does. Covers…
Agent
Specialized agents to spawn for scoped work, so verbose output stays out of the main context window and independent tasks run in parallel. Each entry is a ready-to-paste system prompt plus when to use and tool scope.
