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 | $0.22175 | $0.22175 |
| Opus 5 | $0.11088 | $0.11088 |
| Sonnet 5 | $0.04435 | $0.04435 |
| Haiku 4.5 | $0.02218 | $0.02218 |
Grade A, and why
counterpoise-ledger 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 9d 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.
How it starts

Project Overview
Counterpoise is a multi-book personal finance accounting application built with Next.js 16, implementing true double-entry bookkeeping with investment tracking. The app uses a PostgreSQL database for all data storage, supports user authentication, and includes a Moneydance import tool.
Development Commands
Essential Commands
docker volume create counterpoise_pgdata # Create persistent data volume (first time only)
docker compose up -d # Start PostgreSQL (required before dev/test)
npm run dev # Start development server (http://localhost:3000)
npm run build # Build for production
npm run lint # Run ESLint
npx tsc --noEmit # Type-check without emitting files
# Testing
npm run db:create-test-dbs # Create counterpoise_dev + per-worker test databases (one-time setup)
npm test # Run all unit tests with Vitest
npm run test:ui # Run tests with interactive UI
npm run test:coverage # Generate test coverage report
npm run test:e2e # Run Playwright E2E tests
# Database
npm run db:generate # Generate migrations from /db/schema.ts
npm run db:migrate # Apply pending migrations to the database
npm run db:seed # Seed database with sample data (destructive: resets entire DB)
npm run db:seed -- --book-id 2 # Seed into existing book (replaces book data only)
npm run db:rebuild-lots # Regenerate investment lots from splits (guarded; --force to override)
npx drizzle-kit studio # Open Drizzle Studio (database GUI, requires DATABASE_URL)
# MCP
npm run mcp:dev # Start MCP server for AI access to accounting data
# MCP (Docker — production)
docker exec -i counterpoise-app-1 node /app/mcp-server.mjs # Run MCP server via Docker
# Release & Deploy
./scripts/release.sh [patch|minor|major] # Bump version, tag, push, create PR to main
./scripts/deploy.sh # Pull main, rebuild Docker, restart app
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.
