This is LedgerHQ/ledger-live's own configuration. It tells Codex and OpenCode 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 A, and why

ledger-live AGENTS.md 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 3d 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.

Project Context

Overview

"Ledger Wallet" (formerly "ledger-live") is a crypto wallet. This pnpm and Nx monorepo contains multiple frontend apps and over 150 library packages. See the root README for an overview.

We are working towards consistency across all those packages but each workspace has it's own details. Read local README files relevant to where you are working.

Where to add new code

When creating a new package, follow docs/new-library.md guidelines.

Repo Commands

Prefer commands given in local README files. For example appls like Ledger Wallet Desktop and Ledger Wallet Mobile have very specific commands for setup, dev and build commands.

For general test, build and check recipes see /docs/repo-commands.md, which also contains notes on Nx, filtering and aliases.

When a task includes Jira or Confluence links, use Atlassian MCP to fetch and read the referenced ticket or page by default before summarizing, planning, or implementing.

When a task involves GitHub — pull requests, issues, CI checks, or releases — use the gh CLI by default.

Validate Before Finishing

Always follow the validate-before-finishing instructions before completing code changes.

Keep the external services catalog up to date

  • /docs/services.md lists every external service the apps contact (domain, how it's managed, scope/team).
  • When you add, remove, or change a service — a new entry in libs/env/src/env.ts, a hardcoded endpoint, a coin/family config change, or a new SDK dependency that phones home — update the matching table in docs/services.md.

Read READMEs for packages where you're working

See examples:

  • Entity packages (domain/entity/): read domain/entity/README.md
  • API packages (domain/api/): read domain/api/README.md
  • Shared packages (shared/**): read shared/README.md
  • Support packages (support/**): read support/README.md

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.
