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

blog AGENTS.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 4d 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.

This file provides guidance to coding agents when working with code in this repository.

Quick Start

# First time setup
pnpm install                    # ~15-20s
pnpm playwright install --with-deps  # E2E browsers (first time only)

# Development
pnpm dev                        # Start dev server at localhost:3000 (~1s)

# Common Tasks
pnpm lint                       # Run all linters (~5-10s)
pnpm lint:fix                   # Auto-fix linting issues
pnpm test                       # Unit tests (watch mode)
pnpm test:all                   # Unit tests with coverage (~35-40s)
pnpm e2e                        # E2E tests (~5-10min, includes build)
pnpm build                      # Production build (~30-40s)

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.
