pith: Instructions file for Claude Code

CLAUDE.md

pith CLAUDE.md is an instructions file for Claude Code from SiluPanda/pith. It costs 610 tokens per session, scanned A, original, MIT.

Project instructions for Pith, an AI-native task-management system organized as a monorepo, meaning one repository containing several related packages.

In plain words
What is it for?
Use them when developing, testing, migrating the database, seeding data, or navigating the packages in the Pith codebase.
Why use it?
They explain the project's architecture, database, API, web interface, command-line tool, AI integration, and common commands so an agent can work in the correct package and run the right checks.

This is SiluPanda/pith's own configuration. It tells Claude Code how to work on pith itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything pith configures →

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.

Security

Grade A, and why

pith 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.

CLAUDE.md — Pith Agent Instructions

This file provides context for AI agents (Claude Code, Cursor, etc.) working on the Pith codebase.

Project Overview

Pith is an AI-native task management system. Monorepo with 7 packages:

  • packages/core — Shared Zod schemas, types, and constants
  • packages/db — Drizzle ORM schema, migrations, PostgreSQL client
  • packages/server — Fastify API server (all routes, auth, middleware)
  • packages/ai — Vercel AI SDK integration (optional AI features)
  • packages/mcp-server — MCP server (stdio + HTTP transports)
  • packages/cli — Commander.js CLI
  • packages/web — React + Vite web UI

Key Commands

npm install          # Install all dependencies
npm run dev          # Start API server (port 3456)
npm test             # Run all tests (128 tests)
npm run db:migrate   # Run database migrations (from packages/db/)
npm run db:seed      # Seed sample data

Architecture

  • API: Fastify with Zod validation, JWT + API key auth, RBAC
  • Database: PostgreSQL 16+ via Drizzle ORM
  • MCP: @modelcontextprotocol/sdk with stdio and HTTP/SSE transports
  • AI: Vercel AI SDK, provider-agnostic, graceful degradation
  • Testing: Vitest + Fastify inject (no Supertest needed)

Database

Connection via DATABASE_URL env var. Tables: users, projects, tasks, comments, activities, agent_sessions, labels, views, webhooks, webhook_deliveries, task_links, time_entries.

Testing

Tests are in packages/server/src/__tests__/ and packages/mcp-server/src/__tests__/. Run with npm test. Tests use a real PostgreSQL database (no mocks). The cleanDatabase() helper truncates all tables between test groups.

Code Patterns

  • Routes are in packages/server/src/routes/ as Fastify plugins
  • Response format: success(data), paginated(items, total, limit, offset), error(code, message)
  • Auth: authenticate hook + authorize(...roles) for RBAC
  • All list endpoints support pagination via limit and offset query params
  • Activity logging on task mutations (status_changed, priority_changed, assigned, etc.)

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.
