Hacker News

I'm a recent grad from UMich and built AgentShield because agentic AI is moving fast but payment safety hasn't caught up. Agents are already being handed API keys, stablecoin wallets, and payment credentials - if one misbehaves, gets prompt injected, or makes a bad call, nothing understands the agent's intent well enough to stop it.

Every spend request runs through four checks before money is allowed to move:

1. Quantitative (Redis) - Is the agent within its daily budget? Is it sending the same transaction over and over?

2. Policy (Postgres) - Is the vendor blocked? Is the amount too high to auto-approve? Is the stablecoin/network/address allowed?

3. Semantic (Claude Haiku) - Does the stated goal actually match what's being purchased?

4. Goal Drift (Claude Haiku) - Is this purchase within what the agent is supposed to be doing at all?

Checks 1 and 2 run sequentially — if either hard-denies, Claude never gets called. Checks 3 and 4 run in parallel via asyncio.gather.

One verdict comes back: SAFE, SUSPICIOUS, or MALICIOUS.

Full product — live dashboard, auth, HITL approval flows, spend monitoring. Completely free.

Looking for feedback, especially from anyone running spending agents in production.

Hey HN,

I built Crisper because every dictation tool I tried either sent audio to the cloud or gave me raw, messy transcripts I still had to fix.

Crisper runs entirely on-device — no network calls, no account, no subscription. It does two things in sequence: transcribes using a speech model, then runs a local LM pass to strip filler words, fix grammar, and make the output sound intentional. The whole thing takes ~1–2 seconds on Apple Silicon.

A floating hotkey pill sits above every window. When you're done recording, it auto-pastes back into whatever app you were in before — Slack, Notion, VS Code, anything.

A few things I'm happy with: - Three recording modes (toggle, hold-to-record, re-paste last) — all rebindable - Full transcript library with source app, timestamp, and audio playback - Fully offline after first-run model download

Free to download. Would love feedback on the AI polish quality especially — that's the part I'm still tuning.

A tool/toy that lets you connect to your Steam wishlist to calculate the total list/current price of all the games on it.

There's a shallow, jokey purpose to it ("I could buy a BMW with this amount!"), but the real purpose is to demonstrate how we can do a better job of portraying a game catalog. I often wishlist stuff, then it pops up in a "Hey, it's on sale!" email months later. In that email, there's a banner capsule, but that doesn't help my brain remember why I added it.

To that end, after you get the bill, you get a nice, flat feed of stuff about all the titles you've wishlisted over the years. It's all stuff that developers painstakingly put together, but which Steam tucks away under the fold of a game's Store page.

Anyway, my wishlist came to about $250. My QA guy is up to $19k. Give it a go; hope you enjoy it!
