tech-stack

A set of project rules for using pnpm in a workspace monorepo, where several packages live in one repository. It documents dependency declarations, common commands, and links between local packages.

In plain words
What is it for?
Managing dependencies with pnpm, running scripts in one or many packages, and using the workspace protocol for local package references.
Why use it?
It gives developers consistent ways to install dependencies, run commands, and reference packages within the repository.

Getting it into your agent

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.

Security

Grade A, and why

tech-stack 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 yesterday.

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.

Tech Stack

This project uses:

pnpm Workspace & Monorepo Best Practices

This repository is structured as a pnpm workspace (see pnpm-workspace.yaml).

Common Commands

  • Install All Dependencies: pnpm install
  • Add Dependency:
    • To current package: pnpm add <pkg>
    • As dev dependency: pnpm add -D <pkg>
    • To workspace root: pnpm add -w <pkg>
  • Run Scripts:
    • In current package: pnpm <script> (e.g., pnpm test)
    • In all packages: pnpm -r <script>
    • In specific package: pnpm --filter <pkg-name> <script>

Workspace Protocol

Always use the workspace: protocol when referencing local packages in package.json:

{
  "dependencies": {
    "@my-project/common": "workspace:*"
  }
}

Dependency Management

pnpm uses a content-addressable store and a non-flat node_modules structure. This ensures:

  • Strictness: You cannot access dependencies that are not explicitly declared in your package.json.
  • Efficiency: Disk space is saved by sharing package files across projects.
Changes

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.
