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 5.1 | $0.00061 | $0.00741 |
| Opus 5.5 | $0.00024 | $0.00296 |
| Sonnet 5.5 | $0.00012 | $0.00148 |
| Haiku 4.5 | $0.00006 | $0.00074 |
Grade A, and why
ldls-native 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.
How it starts
The opening of the file, as written. The whole thing — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Lumen UI React Native
Read the Lumen rules first
Lumen ships its own rules for components, the lx style system and tokens. Read them before writing UI:
apps/ledger-live-mobile/node_modules/@ledgerhq/lumen-ui-rnative/ai-rules/RULES.md.
The file exists once pnpm i has run. pnpm links @ledgerhq/lumen-ui-rnative under the packages that
depend on it, not at the repo root. If the path is missing, open ai-rules/RULES.md in the installed
@ledgerhq/lumen-ui-rnative package of any native consumer.
Map the contract onto Lumen
A universal component has one platform-neutral contract in X.types.ts, see the
universal components ADR. The native file X.native.tsx
translates it to Lumen, one line per prop:
Contract (X.types.ts) |
Native implementation (X.native.tsx) |
|---|---|
Intent callback, onOpenContacts() |
onPress={onOpenContacts} |
Value callback, onSearchQueryChange |
onChangeText={onSearchQueryChange} |
testID |
testID={testID} |
// ContactsButton.native.tsx
import {
Card,
CardContent,
CardContentTitle,
CardHeader,
CardLeading,
} from "@ledgerhq/lumen-ui-rnative";
import type { ContactsButtonProps } from "./ContactsButton.types";
export function ContactsButton({ title, onOpenContacts, testID }: ContactsButtonProps) {
return (
<Card type="interactive" onPress={onOpenContacts} testID={testID}>
<CardHeader>
<CardLeading>
<CardContent>
<CardContentTitle>{title}</CardContentTitle>
</CardContent>
</CardLeading>
</CardHeader>
</Card>
);
}
What stays in the native file
These never appear in the contract. The native file owns them:
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.

ldls-native is a skill published in the GitHub repository LedgerHQ/ledger-live (624 stars, last pushed yesterday), licensed MIT. It adds 61 tokens to every session and 741 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
