At a glance

Run unit tests scoped to files changed in the current branch.

  • The user asks to run tests
  • Calls pnpm and git
  • Validate changes

What it does

Run Tests is an agent skill from LedgerHQ/ledger-live. Run unit tests scoped to files changed in the current branch. Use when the user asks to run tests, validate changes, or before a PR.

Its SKILL.md is about 160 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 Testing & QA, covering Unit testing. It works with pnpm. The repository describes itself as: Mono-repository for Ledger Wallet apps and related packages. The licence is MIT.

When your agent uses it

  • The user asks to run tests
  • Validate changes

Example prompts

  • “/run-tests”

What it can do on your machine

Read from SKILL.md and the folder at commit 30d7883. 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

    Shell commands in SKILL.md call:

    • pnpm
    • git

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

  • Network

    No URLs in SKILL.md. Its commands use pnpm and git, which can reach the network depending on how they are called.

    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

Run Tests loads about 161 tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 52 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~36
When it runs · the whole SKILL.md, loaded when a task matches
~161

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.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

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.

Run Tests

Run tests only on files touched in this branch:

bash
git diff --name-only develop..HEAD

Map to scope:

  • apps/ledger-live-desktop/ → pnpm desktop test:jest "path/to/file"
  • apps/ledger-live-mobile/ → pnpm mobile test:jest "path/to/file"
  • libs/<name>/ → pnpm --filter <package-name> test "path/to/file"

Fix failures one at a time — never skip or comment out a test.

Report: ✅ X suites pass or ❌ failure in ... → Fixed: [description]
