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

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 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

Core Libraries

  • @tanstack/react-query: Data fetching/async (handwritten query keys in @repo/react and app lib/query-keys.ts)
  • @repo/react: React Query hooks and helpers only—never UI components. Route-specific UI (e.g. login form) lives in apps, collocated by route
  • nuqs: URL-based state (search/filters/tabs/pagination)
  • zod: Schema validation
  • @repo/utils: Utility library
  • lodash-es: Common operations (per-function imports)
  • ahooks: useSetState (grouped state), useLocalStorageState (localStorage)

Essential Patterns

Query keys: handwritten in @repo/react and apps/web/lib/query-keys.ts. nuqs for URL-shareable state, @repo/core for API clients. Auth: see @.cursor/rules/frontend/auth.mdc

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.
