ledger-live: Skill for Claude Code

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

e2e-desktop-onboard is a skill for Claude Code, Codex from LedgerHQ/ledger-live. It costs 26 tokens per session (2,984 once invoked), scanned A, 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.

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

e2e-desktop-onboard 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 11d 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.

description: Interactive setup wizard for running desktop E2E (Playwright + Speculos) tests locally

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.
