monorepo-deps

monorepo-deps is a skill for Claude Code from allemaar/open-skills. It costs 118 tokens per session (3,636 once invoked), scanned A, original, Apache-2.0.

A dependency-maintenance workflow for an npm monorepo, a repository containing multiple related JavaScript packages. It uses syncpack and manypkg to check, update, and align package dependencies.

In plain words
What is it for?
Use it to check or fix dependency mismatches, update packages, enforce version rules, repair syncpack configuration, and keep workspace dependencies consistent.
Why use it?
It finds version differences between packages, fixes what can be fixed automatically, resynchronizes the lock file, and maintains the configuration that controls these checks.

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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-deps 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 12d 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 — 243 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/monorepo-deps

Run the full syncpack + manypkg flow on an npm monorepo: check version mismatches, fix what's auto-fixable, bump deps via npm update with handler-set major caps in root overrides, verify, and maintain the .syncpackrc.json that governs all of this. One skill covers the whole loop. Use the underlying single-purpose skills (syncpack-usage, syncpack-cli, syncpack-config, manypkg-usage) when you need API or config detail beyond what this orchestrator carries inline.

Structured execution spec: protocol.yon. Read it for the canonical rules and step sequence; this file is explanation. The two must stay in sync — if you edit one, update the other and refresh the @STAMP date.

Boundary

Use /monorepo-deps for the end-to-end loop on an npm workspaces monorepo: check + fix + update + lock-resync + config maintenance. Use the per-tool reference skills directly when you need a specific command surface:

  • syncpack-usage — overview, decision gate, version-group behaviors
  • syncpack-cli — every CLI flag, glob syntax, --dependency-types values
  • syncpack-config.syncpackrc.json schema reference (versionGroups, semverGroups, customTypes)
  • manypkg-usage — manypkg CLI + rule names (EXTERNAL_MISMATCH, INTERNAL_MISMATCH, …)

This skill assumes npm (not pnpm or yarn). For pnpm/yarn monorepos the syncpack story is the same but the lock-file commands differ — adapt as needed.

Phase 1 — Detect prerequisites

Before doing anything, check whether syncpack and @manypkg/cli are installed in the target repo. The skill's behavior splits on this:

State Action
Both installed Proceed silently to Phase 2 — no asking, no install
One or both missing Stop. Explain to the user what each tool does + why useful (see prose below), then ASK with a single decision: install + continue, or abort. On reject → stop. On accept → install as root devDeps, then continue.

Detection: read the root package.json and check devDependencies for syncpack and @manypkg/cli. (Don't shell out for this — the file is cheap to read.)

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.
