ledger-live: Skill for Claude Code

.agents/skills/e2e-desktop-onboard/SKILL.md

e2e-desktop-onboard is a skill for Claude Code from LedgerHQ/ledger-live. It costs 47 tokens per session (2,981 once invoked), scanned E, original, MIT.

An interactive setup guide for running desktop end-to-end tests, which test a complete user flow, with Playwright and a simulated hardware wallet.

In plain words
What is it for?
Use it to prepare Ledger Live Desktop for local tests using the Speculos hardware-wallet simulator and Docker, without changing test files.
Why use it?
It checks the computer's prerequisites and guides fixes step by step, so local test setup is less error-prone.

Skill for Claude Code

Written for Claude Code: disable-model-invocation in frontmatter. Also seen: names the TodoWrite tool; installed under .agents/ (shared by several agents).

This is LedgerHQ/ledger-live's own configuration. It tells Claude Code how to work on ledger-live itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ledger-live configures →

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 E, and why

e2e-desktop-onboard scanned grade E with 3 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.

How it starts

The opening of the file, as written. The whole thing — 294 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Desktop E2E Onboarding

You are an interactive setup wizard that checks the developer's machine and guides them through every prerequisite for running Ledger Live Desktop E2E tests (Playwright + Speculos) locally.

This command sets up Speculos mode (MOCK=0) exclusively -- real hardware wallet simulation via Docker. Mock mode does not require onboarding.

Work through each phase sequentially. For each check, run the shell command, report pass/fail, and if it fails, guide the user through the fix before moving on. Use TodoWrite to track progress across phases.

All commands assume the working directory is the repository root (ledger-live/). Before Phase 1, verify with git rev-parse --show-toplevel and cd there if needed.

CRITICAL SECURITY RULE: NEVER print, log, or display the value of SEED or any secret. Only confirm whether it is set or not.

DO NOT MODIFY TEST CODE: This command is strictly for environment setup and validation. Never create, edit, or delete any test file (specs, page objects, helpers, fixtures, or any file under e2e/).


Phase 1: System Tools

Do NOT hardcode expected versions. Read the source-of-truth config files to determine what's required:

Tool Source of truth How to read
Node mise.toml grep "^node" mise.toml
pnpm mise.toml grep "^pnpm" mise.toml

First, read the config files to determine expected versions. Then run these checks:

Check Command Expected
Docker docker --version Installed (required -- Speculos runs in Docker)
Docker running docker info > /dev/null 2>&1 Docker Desktop is running
Mise mise --version Installed (required)
Node node --version See version policy below
pnpm pnpm --version See version policy below

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.

e2e-desktop-onboard is a skill published in the GitHub repository LedgerHQ/ledger-live (624 stars, last pushed yesterday), licensed MIT. It adds 47 tokens to every session and 2,981 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it E with 3 findings (downloads and executes remote code, recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
