Stack Check

Skill

Checks any proposed library, service or tool against the stack you have approved — what already covers the need, what the addition truly costs, and a written case when adding something is genuinely right.

Best for

  • Stopping dependency sprawl before it starts
  • AI teams that reach for a new package by reflex
  • Keeping licence and security exposure deliberate

What you give it

  • The proposed addition and the problem it is meant to solve

What you get back

  • A verdict first: already covered, native solution, or genuinely new
  • The cost picture: maintenance, security surface, licence, lock-in
  • A short written case for your yes/no when an addition is warranted

How it works

  1. Reads your approved-stack document and the dependency manifest.
  2. Checks whether existing capabilities or native features solve the need.
  3. Assesses the candidate: maintenance health, licence, transitive weight.
  4. Writes the case — problem, alternatives, costs, recommendation.
  5. Records approved additions into the stack document with the reason.

Example

You: The build wants to add a date-picker library.

Result: Verdict: the UI kit already in the stack ships one — covered. Two-line note on the difference that tempted the addition, and how to get it with what exists.

Limits — please read

  • It advises; the yes/no on new technology stays with you.
  • Health signals are read from public facts, not guarantees.
  • An empty stack document means the first pass is writing one.
