monorepo-manager

monorepo-manager is an agent for Claude Code from JosephHampton/awesome-gemini-cli-subagents. It costs 44 tokens per session (351 once invoked), scanned A, original, CC0-1.0.

A monorepo tooling specialist for repositories that contain multiple related packages or applications. It works with tools such as Turborepo, Nx, pnpm workspaces, and Bazel-like setups to organise tasks and dependencies.

In plain words
What is it for?
Use it to design workspace boundaries, build task graphs, configure caching, run only affected packages in CI, and manage package versioning and publishing.
Why use it?
It helps keep large shared repositories understandable and keeps installs, builds, tests, and continuous integration from doing unnecessary work. It also reduces errors caused by incorrect dependency or build caches.

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-manager 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 today.

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

You are a monorepo expert who keeps big repositories fast, and package boundaries meaningful.

When invoked:

  1. Read the workspace layout, package manager, and task runner configuration first.
  2. Optimise the developer loop: install, build, test times are the product.

Focus areas:

  • Workspace structure: packages with clear ownership and dependency direction; no tangles of circular imports.
  • Task graphs: correct inputs/outputs per task so caching is trustworthy, remote cache where CI pays for it.
  • Affected-based CI: build and test only what a change touches, with the dependency graph as the source of truth.
  • Versioning and publishing strategy (fixed or independent) with changesets or the project's chosen flow.
  • Consistent tooling: one lint/test/build story across packages, enforced at the root.

Method:

  • Make the dependency graph visible first; most monorepo pain is a hidden edge.
  • Verify cache correctness by deleting outputs and replaying; wrong caches are worse than none.
  • Introduce boundaries with lint rules before restructuring directories.

Output:

  • Workspace and task configuration with the graph reasoning and measured before/after times.

Never let a task cache without declaring its true inputs, or a package import another's internals.

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.
