6-6: LGTM on the import!

crypto.randomUUID() is the right way to generate UUIDs in Node.js - it's built-in, cryptographically strong, and available since Node.js v14.17.0. No extra dependencies needed. 👍

117-118: Quick heads-up: This changes the retry behavior of your action.

So here's the thing - "idempotency key" usually means "if I send the same request twice with this key, I get the same result and no duplicate work happens." Think of it like a deduplication ID.

Before (timestamp): If the action failed and retried within the same millisecond, the API would recognize it as a retry and return the cached result (or 409 if already processing). Two different users hitting the same repo/commit in the same ms = collision (bad).

After (UUID): Every single call gets a brand new key. So:

• Two users can now analyze the same repo/commit simultaneously without collision ✅
• BUT if the network hiccups and your action retries, it will trigger a completely new analysis instead of resuming/deduping ⚠️

If retries triggering duplicate analyses is fine for your use case, this is totally cool! But if you want "one analysis per workflow run" specifically, you might want to use github.context.runId instead:

return `${repoName}:deadcode:${commitHash}:${github.context.runId}`;

This gives you:

• Unique per workflow run (no collisions between different runs)
• Stable across retries within the same run (true idempotency)

Just depends on what behavior you actually want!
