What it does

Configuration is an agent skill from LedgerHQ/ledger-live. Pick the home for a configuration value — environment variable, backend URL, partner key, public token, per-environment constant, build secret — and take an existing one out of @shared/env / @ledgerhq/live-env (getEnv, setEnv, useEnv, injectDefinitions). Read before adding or changing any env var, .env entry or getEnv call site.

Its SKILL.md is about 290 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Secrets management. The repository describes itself as: Mono-repository for Ledger Wallet apps and related packages. The licence is MIT.

When your agent uses it

  • Tasks that involve Secrets management

Example prompts

  • “/configuration”

What it can do on your machine

Read from SKILL.md and the folder at commit 9c51f17. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Configuration loads about 285 tokens when it runs. Until then it costs about 90 tokens; SKILL.md has 109 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~90
When it runs · the whole SKILL.md, loaded when a task matches
~285

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Pick the home for a configuration value — environment variable, backend URL, partner key, public token, per-environment constant, build secret — and take an existing one out of `@shared/env` / `@ledgerhq/live-env` (`getEnv`, `setEnv`, `useEnv`, `injectDefinitions`). Read before adding or changing any env var, `.env` entry or `getEnv` call site.

Configuration

Read /docs/configuration.md — the canonical guide. It opens with a Pattern → home table mapping each kind of value to exactly one home, and has one section per home with this repo's mechanics and worked examples. Jump to the row that matches instead of paraphrasing the doc in chat.

Two rules to apply without reading further:

  • @shared/env and @ledgerhq/live-env are deprecated: no new definition, no new call site, including in tests. Migrating a variable means deleting its definition in the same PR.
  • A value in an app's .env file ships inside the artifact. Public configuration only; a real build secret stays in the workflow step and never reaches app code.

What does Configuration need to run?

SKILL.md names no scripts, command-line tools or credentials: Configuration is instructions for the agent only.

How many tokens does Configuration use?

About 285 tokens (SKILL.md is roughly 1.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
