moon-init

moon-init is a command for coding agents from hyperb1iss/moonrepo-skill. It costs 19 tokens per session (389 once invoked), scanned A, original, Apache-2.0.

A command for starting Moon in a repository. Moon is a build and task system for repositories containing multiple related projects, and it stores its configuration in a .moon directory.

In plain words
What is it for?
Use it when introducing Moon to a repository, adding language toolchains such as Node.js, Rust, or Python, and reviewing workspace, task, or version configuration.
Why use it?
It creates the initial workspace and toolchain settings needed before Moon can discover projects and run their tasks.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add commands/hyperb1iss/moonrepo-skill/moon-init
Clone the repo
git clone --depth 1 https://github.com/hyperb1iss/moonrepo-skill

Or install moonrepo, the plugin that ships this one along with the rest of its 2 skills, 5 commands, 3 agents.

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

moon-init 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 4d 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.

What it actually says

Initialize Moon Workspace

Initialize moon in the current repository.

Process

  1. Check if moon is already initialized (look for .moon/ directory)
  2. If not initialized, run moon init
  3. If initializing with a specific toolchain, run moon toolchain add <tool> (v2)

Commands

# Check current state
ls -la .moon/ 2>/dev/null || echo "Moon not initialized"

# Initialize moon
moon init

# Add toolchain (v2 - replaces 'moon init <tool>')
moon toolchain add node
moon toolchain add rust
moon toolchain add python

Post-Init Configuration

After initialization, review and customize:

  1. .moon/workspace.yml - Project discovery patterns
  2. .moon/toolchains.yml - Language versions (v2: plural)
  3. .moon/tasks/*.yml - Global inherited tasks (v2: directory)

Example Workspace Setup

# .moon/workspace.yml
$schema: "https://moonrepo.dev/schemas/workspace.json"

projects:
  - "apps/*"
  - "packages/*"

vcs:
  client: "git"
  defaultBranch: "main"

pipeline:
  archivableTargets:
    - ":build"

Example Toolchain

# .moon/toolchains.yml (v2: plural, flat structure)
$schema: "https://moonrepo.dev/schemas/toolchains.json"

javascript:
  packageManager: "pnpm"

node:
  version: "20.10.0"

pnpm:
  version: "8.12.0"

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.
