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

project-structure 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.

What it actually says

Project Structure

This document outlines the structure of the monorepo, detailing the purpose of each package and application directory.

apps/

This directory contains the applications of the monorepo.

  • apps/web: This is the main frontend application, built with Astro and React. It includes all UI components, pages, layouts, and client-side logic.

packages/

This directory contains shared packages used by the applications.

  • packages/api: This package holds the tRPC API. It's responsible for defining API procedures, business logic, and type-safe communication between the client and server.

  • packages/db: This package manages all database-related concerns. It uses Kysely for type-safe query building and contains the database schema, migrations, and seeding scripts.

  • packages/utils: A collection of shared utility functions and types that are used across different packages and applications within the monorepo.

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.
