packmind: Instructions file for Claude Code

CLAUDE.md

packmind CLAUDE.md is an instructions file for Claude Code from PackmindHub/packmind. It costs 835 tokens per session, scanned A, original, Apache-2.0.

Repository guidance for coding agents working on Packmind, an Nx monorepo: one code repository containing multiple applications and shared packages.

In plain words
What is it for?
Use it when starting the Docker-based development environment or testing, linting, and building an application or shared package.
Why use it?
It maps the applications, packages, databases, cache, background jobs, and Nx commands, so developers know where code belongs and how to run checks locally.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

This is PackmindHub/packmind's own configuration. It tells Claude Code how to work on packmind 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 packmind 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

packmind 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 1mo 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.

Nx Monorepo Structure

This is an Nx monorepo containing applications and reusable packages.

Core Technologies

  • Runtime: Node.js (version specified in .nvmrc)
  • Language: TypeScript
  • Database: PostgreSQL with TypeORM for entity persistence
  • Cache: Redis for caching
  • Background Jobs: BullMQ for job queue management
  • Testing: Jest with @swc/jest as test runner

Directory Structure

  • apps/ - Deployable applications (API, frontend, CLI, e2e tests, docs)
  • packages/ - Reusable domain and infrastructure packages shared across apps
  • .github/workflows/ - CI/CD pipelines for build, test, quality checks, and deployment

Local Development Environment

Local development uses Docker Compose to run all services (API, frontend, Redis, PostgreSQL). Docker Compose automatically provisions PostgreSQL and Redis - no manual setup required.

Working with Nx

The following commands apply for both NX apps and packages (use ./node_modules/.bin/nx show projects to list actual apps and packages.)

  • Test a project: ./node_modules/.bin/nx test <project-name>
  • Lint a project: ./node_modules/.bin/nx lint <project-name>
  • Build a project: ./node_modules/.bin/nx build <project-name>
  • Test affected projects: pnpm run test:staged
  • Lint affected projects: pnpm run lint:staged

Code Quality

  • Linting: ./node_modules/.bin/nx lint <project-name> runs ESLint, using the config file eslint.config.mjs.
  • Formatting: Prettier is used for code formatting. You don't have to run it, it's set as a pre-commit hook.

Commands

  • When running commands, ensure you use the correct Node version (see .nvmrc at the project's root level)
  • When renaming or moving a file that is commited to git, use git mv instead of mv
  • ensure the env variable PACKMIND_EDITION is properly set to oss
  • when asked to execute packmind-cli, use node ./dist/apps/cli/main.cjs
  • Some default skills use version-routed directories (packmind-versions/<version>/) and ask you to run packmind --version to pick the right one. Since you already run the local build with node ./dist/apps/cli/main.cjs, you always have the latest — skip the --version check and use the highest-numbered packmind-versions/ directory (currently 0.35.0 for both packmind-onboard and packmind-update-playbook). There is no next/ directory.

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.
