What is platypus CLAUDE.md?

A project instruction file for Platypus, a full-stack application for building and managing AI agents, covering setup, commands, architecture, and constraints. It also explains the monorepo layout, where several related projects share one repository.

Use it as a reference when working across the frontend, backend, database, authentication, and shared packages in Platypus.

It gives coding agents and developers the project context needed to install, build, test, format, lint, and type-check the application correctly.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.01428	$0.01428
Opus 5	$0.00714	$0.00714
Sonnet 5	$0.00286	$0.00286
Haiku 4.5	$0.00143	$0.00143

Security

Grade A, and why

platypus CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

Platypus is a full-stack app for building and managing AI agents with tool support and multi-provider capabilities. pnpm workspaces + Turborepo monorepo.

Setup & Commands

pnpm install
cp apps/frontend/.env.example apps/frontend/.env
cp apps/backend/.env.example apps/backend/.env

pnpm dev               # frontend + backend + local Postgres
pnpm drizzle-kit-push  # apply schema changes (requires `pnpm dev` running)
pnpm build
pnpm format
pnpm lint
pnpm typecheck         # tsc --noEmit (apps/backend, apps/frontend); gated in CI
pnpm test              # all tests (Vitest, orchestrated by Turborepo)

Per-package: pnpm --filter <pkg> test|test:watch|test:coverage|typecheck.

pnpm typecheck runs tsc --noEmit for every package exposing a typecheck script, test files included. CI fails on any type error — ESLint does not catch them, so run it before pushing. Other packages join the gate by adding their own typecheck script.

Default admin on first startup: [email protected] / admin123 (override via ADMIN_EMAIL / ADMIN_PASSWORD).

Monorepo Layout

apps/backend — Hono.js REST API, Drizzle ORM (Postgres 17), better-auth at /auth/*. Schema in src/db/, routes in src/routes/, run lifecycle in src/runs/. Entry: apps/backend/index.ts.
apps/frontend — Next.js 16 App Router. Multi-tenant routes under app/[orgId]/workspace/[workspaceId]/.... Tailwind v4 + Radix.
packages/schemas — Shared Zod schemas (@platypus/schemas). Each domain model has full / create / update variants.

Domain hierarchy: Organization → Workspace → Chat / Agent / MCP / Provider.

Known Constraints

drizzle-kit push applies DDL only — it does NOT run migration .sql files. Data migrations (e.g. custom backfills) run in production via scripts/migrate.ts (drizzle-kit migrate) but are skipped by the dev push flow. In dev, apply any needed data changes manually (e.g. attach org-scoped Shared resources via the UI).
Postgres 18 is not supported (Drizzle ORM incompatibility).
No TypeScript parameter properties. Node's strip-only TS mode rejects constructor(private x: T) shorthand. Declare fields explicitly and assign in the constructor body.
Format with Prettier conventions.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
