Your agent writes SDK code from memory. That memory is eighteen months old.

The whole idea

Same prompt — "add Stripe payments." The only thing that changes is whether the agent looked things up first.

✗  from memory      stripe.charges.create({ amount: 2000, currency: "usd" })
                     // Charges API — no 3-D Secure, no SCA. Ships, then fails in the EU.

✓  after reading docs stripe.paymentIntents.create({ amount: 2000, currency: "usd" })
                     // current. handles 3DS/SCA. the thing you actually wanted.

The model isn't wrong on purpose. It's confidently repeating an API that was current when it was trained. Airblander makes it check before it writes — so you get the second line, not the first.

What you actually see

You say "add Twilio SMS to this endpoint." Instead of guessing at RestClient (gone in v4), the agent hits a wall:

airblander: BLOCKED — docs not yet fetched for: twilio

Fetch current docs before writing SDK code:
  • twilio: fetch https://www.twilio.com/docs
    or use Context7 query: "twilio"

After fetching, re-attempt the write.

It fetches the docs, learns what's current, and writes the file. One extra step you never have to ask for — and consistently correct code on the other side.

How it works

No model, no magic — three small hooks and one state file. Reading your prompt, gating the write, clearing the SDK once docs are in.

You type: "add stripe payments"
        ↓
  resolve.js  →  sees "stripe" in your message, marks it pending
        ↓
  Agent tries to write payment.ts  (import stripe ...)
        ↓
  detect.js   →  stripe not cleared  →  BLOCKED (exit 2)
        ↓
  Agent fetches stripe.com/docs
        ↓
  clear.js    →  stripe marked cleared ✓
        ↓
  Agent writes the file  →  allowed

State resets every session. Docs fetched yesterday don't count — the library may have changed overnight. SDKs not in the watchlist are still caught, and you can add them permanently with /airblander-add.
