What it does

Codeownership is an agent skill from LedgerHQ/ledger-live. Maintain CODEOWNERS file and team directories. Provides resolve-codeowners.js to annotate files with their owner team — useful to split a large PR by team. Use when working with "/team-/" or splitting monolithic files.

Its SKILL.md is about 690 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `resolve-codeowners.js`).

The repository describes itself as: Mono-repository for Ledger Wallet apps and related packages. The licence is MIT.

Example prompts

“/team-/”

Requirements

Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit a3861a2. 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
Ships script files (JavaScript), which the agent can run.
Shell commands in SKILL.md call:
- node
- git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use 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

Codeownership loads about 687 tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 205 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~59
When it runs · the whole SKILL.md, loaded when a task matches: ~687

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.

name: codeownership
description: Maintain CODEOWNERS file and team directories. Provides resolve-codeowners.js to annotate files with their owner team — useful to split a large PR by team. Use when working with "**/team-*/**" or splitting monolithic files.

Codeownership

Why

To reduce cross-team review bottlenecks

What

Make ownership of team specific directories clear
Organise some directories into team-specific sub-directories
Maintain CODEOWNERS files when team specific directories are added or removed
Split monolithic files or folders that have been identified as being touched by too many teams

Resolving ownership for a list of files

Use resolve-codeowners.js to annotate any list of files with their CODEOWNERS team — handy when splitting a large PR by team owner. It uses the same matcher as the CI check in validate-codeowners, so it resolves exactly as GitHub does (case-sensitive, no install needed).

bash

# From a git diff
git diff --name-only HEAD~1 | node .agents/skills/codeownership/resolve-codeowners.js

# Explicit file list
node .agents/skills/codeownership/resolve-codeowners.js apps/ledger-live-desktop/src/foo.ts libs/env/src/bar.ts

# Override CODEOWNERS location
node .agents/skills/codeownership/resolve-codeowners.js --codeowners /path/to/CODEOWNERS <files...>

Output format (same columns as CODEOWNERS, but resolved to actual files):

apps/ledger-live-desktop/src/main/index.ts  @ledgerhq/platform
apps/ledger-live-desktop/src/renderer/foo.ts  @ledgerhq/wallet-xp
.github/workflows/e2e.yml  @ledgerhq/wallet-ci @ledgerhq/qaa
random/unknown/file.xyz  (no owner)

Semantics: last-rule-wins; ownerless entries appear as (no owner).

Checking CODEOWNERS before pushing

After editing CODEOWNERS, or moving or deleting files it names, run the CI check locally:

bash

node .agents/skills/codeownership/resolve-codeowners.js --check

It fails on rules that match no file, never take effect, re-own narrower rules from a later position, or use an unanchored name that matches in several places. Put defaults such as **/tsconfig* near the top; team-specific rules come after them.

Target

Splitting a monolithic file

Split [foo].ts into [foo]/team-[name]/*.ts

Maintaining team specific directories

Example

/shared/feature-flags/src/flags/ contains team-coin-integration, team-engagement, team-live-devices, etc.

CODEOWNERS defines the owner for each of these:

**/team-coin-integration/         @ledgerhq/coin-integration
**/team-engagement/               @ledgerhq/engagement
**/team-live-devices/             @ledgerhq/live-devices
