bootstrap-monorepo

bootstrap-monorepo is a skill for Claude Code from terrylica/cc-skills. It costs 62 tokens per session (2,216 once invoked), scanned A, original, MIT.

A setup workflow for creating a new monorepo with moon, proto, and Bun across multiple programming languages. A monorepo is one repository that contains several related projects or services.

In plain words
What is it for?
Use it to bootstrap single-language or polyglot repositories, coordinate Rust, Python, Go, and TypeScript projects, and prepare shared build and task workflows.
Why use it?
It gives a new repository a shared structure, pinned tool versions, task orchestration, and defined boundaries between language-specific parts.

    Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.
    Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.

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

bootstrap-monorepo scanned grade A with 1 finding 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 20d 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.

Bootstrap Polyglot Monorepo (moon + proto + Bun, Nx-convergent)

Canonical reference lives in THIS skill:

→ See: references/bootstrap-monorepo.md → Cross-language boundaries: references/cross-language-interop.md — boundary decision ladder + verified tool status (research-verified 2026-06)

Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.

When to Use This Skill

Use this skill when:

  • Starting ANY new repository — single-language or polyglot (the structure scales down)
  • Setting up a moon-orchestrated, proto-pinned, Bun/TypeScript-wired monorepo
  • Wiring engines (Rust/Python/Go) behind contracts under a TS control plane
  • You want the repo Nx-convergent from day one (later nx init is mechanical, not a restructure)

Stack

Tool Responsibility
proto Toolchain versions (bun, python, rust, node, …) pinned in repo-local .prototools
moon Project graph + task orchestration + caching + affected detection (moon ci)
Bun TS runtime for every script, CLI, glue tool, and test; root workspaces
uv / cargo Python / Rust engines invoked natively from moon script: tasks
TypeScript Type-safe control plane (7.0.2+); see TypeScript Configuration below

TypeScript is the control plane; other languages are engines behind language-neutral contracts (JSON Schema 2020-12 / proto) with drift gates and parity tests.

TypeScript Configuration

This skill scaffolds tsconfig.base.json as the canonical reference implementation for all new repositories. Boilerplate path: [templates/tsconfig.base.json](templates/tsconfig.base.json) — the single source of truth for TS7 config shape.

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.
