Symlink or hardlink local packages into nodemodules using npx link.

  • Calls npx and npm
  • Setting up publish-mode hardlinks

What it does

Link is an agent skill from privatenumber/link. Symlink or hardlink local packages into nodemodules using npx link. Use when linking local dependencies for development, setting up publish-mode hardlinks, or configuring link.config.json. Do not use for general symlink/hardlink filesystem questions or npm link internals.

Its SKILL.md is about 840 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with npm. The repository describes itself as: 🔗 A better npm link.

When your agent uses it

  • Linking local dependencies for development
  • Setting up publish-mode hardlinks
  • Configuring link.config.json
  • General symlink/hardlink filesystem questions

Example prompts

  • “/link”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit 8cba39b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npx
    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx and npm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Link loads about 842 tokens when it runs. Until then it costs about 70 tokens; SKILL.md has 306 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~70
When it runs · the whole SKILL.md, loaded when a task matches
~842

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 306 words (~842 tokens).

“Safer npm link alternative — symlinks local packages directly into node_modules without global installs or dependency reinstalls.”
