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.

Model	Per session	Once invoked
Fable 5	$0.00012	$0.02249
Opus 5	$0.00006	$0.01125
Sonnet 5	$0.00002	$0.00450
Haiku 4.5	$0.00001	$0.00225

Measured today against content hash 1d66fde3f0cb, method: parsed. Prices are Anthropic first-party input rates as of 2026-08-30, from the pricing page.

Security

Grade A, and why

design-tokens-guide 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 today.

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.

Design Tokens Workflow

Source of Truth

The single source of truth for all design tokens is located in packages/design-tokens/src/tokens.ts.

Do NOT edit apps/web/src/app/[locale]/tokens.css directly - it's auto-generated.
Do NOT edit apps/mobile/lib/core/theme/generated_theme.dart directly - it's auto-generated.
ALWAYS make changes in packages/design-tokens/src/tokens.ts.

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.

design-tokens-guide is a cursor rule published in the GitHub repository first-fluke/fullstack-starter (222 stars, last pushed 3d ago), licensed MIT. It adds 12 tokens to every session and 2,249 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
