socket-dep-cleanup

A workflow for checking whether one specific external package is unused and removing it when appropriate.

In plain words
What is it for?
Use it to investigate and remove an unnecessary dependency, then verify the project's build and tests.
Why use it?
It prevents accidental removal by searching imports, configuration, scripts, type packages, and indirect references before verification.

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

socket-dep-cleanup 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 yesterday.

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.

Dep Cleanup

Evaluate and remove a single unused dependency from your project. This skill targets ONE specific package at a time - searching the entire codebase for all usages, reporting findings, and performing full removal with build and test verification.

When to Use

  • The user wants to check if a specific dependency is still used
  • The user wants to remove a package they suspect is unused
  • The user is cleaning up after removing a feature or refactoring
  • The user wants to reduce install size by trimming a specific unnecessary package
  • The user asks whether a particular dependency is actually referenced anywhere

Step 1: Identify the Target Package

If the user specifies a package name, use that. Otherwise, ask which package they want to evaluate.

If the user isn't sure which package to evaluate, help them pick one:

  • Check devDependencies first - removing unused dev dependencies is lower risk
  • Look for packages with names that suggest narrow or outdated functionality
  • Suggest running /socket-scan first to get an overview of the dependency landscape

One package at a time. If the user wants to evaluate multiple packages, run this workflow once per package sequentially.

Step 2: Detect the Ecosystem

Identify which ecosystem the target package belongs to by checking manifest and lock files:

Ecosystem Manifest Files
npm package.json + package-lock.json
pnpm package.json + pnpm-lock.yaml
yarn package.json + yarn.lock
PyPI requirements.txt, pyproject.toml, setup.py, setup.cfg, Pipfile
Cargo Cargo.toml
Bundler Gemfile
Maven pom.xml
NuGet *.csproj, packages.config
Go go.mod

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.

socket-dep-cleanup is a skill published in the GitHub repository SocketDev/sauce (2 stars, last pushed 5d ago), licensed MIT. It adds 51 tokens to every session and 2,531 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
