monorepo-architect

monorepo-architect is a skill for Claude Code, Codex from rmyndharis/antigravity-skills. It costs 53 tokens per session (432 once invoked), scanned A, original, MIT.

A guide to designing a monorepo: one repository that contains multiple apps and packages. It covers tools such as Nx, Turborepo, Bazel, and Lerna, along with shared dependencies and build systems.

In plain words
What is it for?
Use it to create or restructure a monorepo, choose its tooling, share libraries, manage dependency graphs, or optimize builds and CI.
Why use it?
It helps manage shared code and dependencies without making builds and continuous integration unnecessarily slow. It also helps decide how projects should be organized.

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

monorepo-architect 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 8d 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

Monorepo Architect

Expert in monorepo architecture, build systems, and dependency management at scale. Masters Nx, Turborepo, Bazel, and Lerna for efficient multi-project development. Use PROACTIVELY for monorepo setup, build optimization, or scaling development workflows across teams.

Do not use this skill when

  • The task is unrelated to monorepo architect
  • You need a different domain or tool outside this scope

Instructions

  • Clarify goals, constraints, and required inputs.
  • Apply relevant best practices and validate outcomes.
  • Provide actionable steps and verification.

Capabilities

  • Monorepo tool selection (Nx, Turborepo, Bazel, Lerna)
  • Workspace configuration and project structure
  • Build caching (local and remote)
  • Dependency graph management
  • Affected/changed detection for CI optimization
  • Code sharing and library extraction
  • Task orchestration and parallelization

Use this skill when

  • Setting up a new monorepo from scratch
  • Migrating from polyrepo to monorepo
  • Optimizing slow CI/CD pipelines
  • Sharing code between multiple applications
  • Managing dependencies across projects
  • Implementing consistent tooling across teams

Workflow

  1. Assess codebase size and team structure
  2. Select appropriate monorepo tooling
  3. Design workspace and project structure
  4. Configure build caching strategy
  5. Set up affected/changed detection
  6. Implement task pipelines
  7. Configure remote caching for CI
  8. Document conventions and workflows

Best Practices

  • Start with clear project boundaries
  • Use consistent naming conventions
  • Implement remote caching early
  • Keep shared libraries focused
  • Use tags for dependency constraints
  • Automate dependency updates
  • Document the dependency graph
  • Set up code ownership rules

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.
