SkillSpector: 4 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00027 | $0.00902 |
| Opus 5.5 | $0.00011 | $0.00361 |
| Sonnet 5.5 | $0.00005 | $0.00180 |
| Haiku 4.5 | $0.00003 | $0.00090 |
Grade A, and why
coin-modules 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 — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Coin Modules
Each blockchain family lives in its own package under libs/coin-modules/coin-<family>.
Package name: @ledgerhq/coin-<family>
Coin modules are one of the few things that still belong in legacy libs/: they migrate to
LedgerHQ/coin-modules, not to the monorepo layers.
Do not create a new coin-module if it fits the ecosystem of an existing one.
No packages other than coin-modules are allowed in libs/coin-modules/.
Directory Layout
| Directory / file | Purpose |
|---|---|
api/ |
Coin Module API surface — implements CoinModuleApi from @ledgerhq/coin-module-framework/api/index; restricted imports apply (see below) |
logic/ |
Core blockchain logic, agnostic of Bridge or API; only depends on network/ and external libs; restricted imports apply (see below) |
network/ |
Communication with explorer / indexer / node; restricted imports apply (see below) |
types/ |
Model definitions, not related to network |
bridge/ (legacy) |
CurrencyBridge + AccountBridge implementation |
signer/ (legacy) |
Hardware wallet signer interface and device address resolver |
Tests: *.unit.test.ts (co-located), *.test.ts (integration, no network), *.integ.test.ts (real network, separate jest.integ.config.js).
Dependencies
Prefer native dependencies from the blockchain foundation and well-established open-source libraries.
Avoid proprietary third-party SDKs or closed-source vendor packages.
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.

coin-modules is a skill published in the GitHub repository LedgerHQ/ledger-live (624 stars, last pushed yesterday), licensed MIT. It adds 27 tokens to every session and 902 once invoked, about $0.0001 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.
