monorepo

monorepo is a skill for Claude Code from nguyenthienthanh/aura-frog. It costs 60 tokens per session (1,155 once invoked), scanned A, original, MIT.

A guide for working in a monorepo, a single repository that contains multiple related packages or projects.

In plain words
What is it for?
It helps identify the right package and coordinate changes across pnpm, npm, Yarn, Rust, Go, and Python workspaces.
Why use it?
It prevents commands, dependencies, tests, and builds from being run against the wrong package.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is Human-readable explanation: see [docs/architecture/HIERARCHICAL_PLANNING.md](../../../docs/architecture/HIERARCHICAL_PLANNING.md).

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AI-consumed reference. Optimized for Claude to read during execution. Human-readable explanation: see docs/architecture/HIERARCHICAL_PLANNING.md or docs/getting-started/ depending on topic.

Monorepo Handling

Monorepos break many assumptions: which package.json is "the" one, where node_modules live, which test command runs, what install actually does. This skill ensures operations target the correct scope.


Detection

On session start or first file edit, check for these markers:

File Tool
pnpm-workspace.yaml pnpm workspaces
turbo.json Turborepo
nx.json Nx
lerna.json Lerna
package.json with "workspaces": [...] npm / yarn workspaces
Cargo.toml with [workspace] Rust workspaces
go.work Go workspaces
pyproject.toml with Poetry/uv workspace config Python workspaces

If detected → monorepo mode ON. Record in workflow state. All subsequent commands must respect package scope.


Key Rules

1. Always identify the target package first

Before any install, test, or build:

  • Which package is the change in? Full path: packages/<name>/
  • Run scoped, not from root: pnpm --filter <name> test

2. Cross-package changes = coordinate

If a change touches package A's API used by package B:

  • List all consumers: grep -r "@your-org/package-a" packages/
  • Update all consumers in the same PR
  • Run tests across all affected packages, not just A

3. Dependency placement matters

Dependency type Where to install
Used by 1 package That package's package.json
Used by 2+ packages Shared config package or root devDependencies
Dev tooling (eslint, prettier, jest) Root
Workspace packages Listed as "workspace:*" in consumer's dependencies

4. Build order respects the dependency graph

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.
