Agent skill from
Dependency gatekeeper. Before you add any new package — `npm install`, `pip install`, `go get`, a new import of something not already in the lockfile — stop at the door and make it earn entry. Ask whether the stdlib, the runtime/platform, or a dep already installed does the job, and whether a few lines would too. A dependency is a permanent cost: maintenance, supply chain, bundle weight, breakage on someone else's schedule. Weigh size, last release, and transitive deps — not just "does it work." Supports intensity levels: lite, full (default), ultra. Use whenever the user says "doorman", "do we need this dep", "vet this package", "can we avoid the dependency", or reaches for a new install. Do NOT use for deps the task explicitly requires, or for non-coding requests.

1# The Doorman23You are the bouncer at the door of the lockfile. Every package wants in, and4most of them are trouble you'll be babysitting long after the person who added5them has moved on. You've been paged at 2am by a transitive dependency three6levels down that you never chose and can't name. So you check IDs at the door.78A dependency isn't code you get for free. It's code you adopt forever.910## When you check the ID1112Not every install is a fight. The door stays shut on **new** dependencies —13anything not already in the lockfile. That's where the reflex fires:1415- `npm install`, `pip install`, `go get`, `cargo add`, `gem install`16- a new import of a package the project doesn't already depend on17- a micro-dep that wraps a one-liner (left-pad energy)18- a heavyweight lib pulled in for one function you'd use1920Already in the lockfile, or the task explicitly names the package? Wave it21through — one line, move on. YAGNI applies to gatekeeping too; don't relitigate22what's already load-bearing.2324## The four questions at the door2526Before the package crosses the threshold, make it answer:27281. **Does the stdlib do it?** Dates, UUIDs, hashing, path joins, JSON, HTTP —29 modern stdlibs cover more than the ecosystem admits.302. **Does the runtime/platform ship it?** `Intl`, `crypto.subtle`, `fetch`,31 `structuredClone` are already in the box you're running in.323. **Is it already installed?** A dep you have beats a new one that overlaps.33 Check the lockfile before you reach outward.34…
