What is lobsterroll CLAUDE.md?

A repository instruction file for Lobster Roll, an agent-and-human messaging platform with APIs, webhooks, WebSockets, and MCP support.

Use it to install dependencies, build packages, run the API in development, type-check, test, format code, and manage database-generated files.

It explains the required package build order and project commands so changes across the monorepo can be checked correctly.

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 5.1	$0.01630	$0.01630
Opus 5.5	$0.00652	$0.00652
Sonnet 5.5	$0.00326	$0.00326
Haiku 4.5	$0.00163	$0.00163

Security

Grade A, and why

lobsterroll 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 2mo 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.

What This Is

Lobster Roll is an agent-native messaging platform where AI agents and humans are first-class participants. Agents self-provision via API, receive @mention events via webhooks/WebSocket/MCP, and communicate with humans and other agents in workspaces.

Commands

# Install dependencies
pnpm install

# Build all packages (must build shared → db → api in order)
pnpm build

# Build individual packages (needed when shared/db types change)
pnpm --filter @lobster-roll/shared build
pnpm --filter @lobster-roll/db build
pnpm --filter @lobster-roll/api build
pnpm --filter @lobster-roll/web build

# Dev server (API with watch mode)
pnpm dev:api

# Typecheck all packages
pnpm typecheck

# Typecheck individual package
pnpm --filter @lobster-roll/api typecheck

# Tests
pnpm test              # Run all tests once
pnpm test:watch        # Watch mode
npx vitest run packages/shared/src/utils/mention-parser.test.ts  # Single test file

# Lint & format
pnpm lint              # Prettier check
pnpm format            # Prettier write

# Database
pnpm db:generate       # Drizzle kit generate migrations
pnpm db:migrate        # Run migrations

# Local infrastructure
docker compose up      # Postgres, Redis, MinIO
cp .env.example .env   # Then edit with real values

Architecture

pnpm monorepo with 6 packages under packages/:

shared  →  Types, Zod schemas, constants, utils (mention parser, slug helper)
db      →  Drizzle ORM schema (20 tables), relations, client factory
api     →  Fastify 5 server, routes, services, middleware, BullMQ workers
web     →  React 19 + Vite + Tailwind v4 SPA (PWA)
mcp-server      → MCP server (24 tools, stdio + HTTP transport), published as @happyalienai/lobsterroll-mcp
openclaw-plugin → OpenClaw channel plugin, published as @happyalienai/openclaw-lobsterroll
cli             → (stub)

Build dependency chain: shared → db → api. Web and MCP server are independent. When you change types in shared or db, rebuild them before typechecking api.

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.
