Show HN: PolicyLayer – Non-custodial spending limits for AI agents

PolicyLayer enforces spending limits on AI agent wallets without custodying private keys.

The problem: AI agents are moving into production with irreversible financial capabilities, but every agent is one bug or prompt injection away from draining a wallet. Traditional options are bad—shared seed phrases (compliance nightmare), custodial wallets (counterparty risk), manual approval (defeats automation), prompt-level limits (easily jailbroken).

How it works: - Drop-in wrapper for existing wallet SDKs (Ethers, Viem, Coinbase CDP, Privy, Solana) - Two-gate enforcement: Gate 1 validates against policies, Gate 2 detects tampering via SHA-256 fingerprinting - Keys never leave your infrastructure—we only see transaction metadata - Fail-closed: if anything fails, transactions stop (not continue) - Policies configured in dashboard: daily caps, per-tx limits, recipient whitelists

Also supports X402 (HTTP 402 payment protocol) for agents paying for APIs—per-endpoint limits, auto-discovery of new paid endpoints, duplicate payment prevention, and circuit breakers.

SDK is open source.

Feedback welcome — what would make this more useful for your agents?

The Anti-Pomodoro Technique: Focus on Taking Breaks, Not Watching the Timer

I’ve never been able to maintain enough focus on a timer. The temptation to get distracted is always strong—and since it’s easy to ignore the timer, I often did.

After failing to follow the Pomodoro method, I’d feel irritated, frustrated, and blame myself. Soon enough, the routine would fall apart, and I’d go back to working in my usual way—without boundaries or timers.

Then I had an epiphany: focusing on the timer forces you into a battle with yourself. And since it’s hard to fight your own subconscious micro-reactions and habits, you end up frustrated. Sticking rigidly to a timer is the wrong goal. The real goal should be taking regular breaks—focus will follow naturally.

To test this idea, I created "Black Screen for Windows" — an app that forcibly blacks out my screens for a few minutes at regular intervals. Usually, that’s 3–5 minutes every 20–30 minutes.

This practice of enforced, regular breaks has not only improved my well-being but also dramatically boosted my productivity—all without the frustration. My ability to focus improved, too, with a small hack: I start with a 30-minute interval, then gradually shorten it until I find a span of time in which I can maintain clean, distraction-free focus.

I find this works better for me than the classic tier-based Pomodoro.

Show HN: LibPDF – The PDF library for TypeScript that I needed

Hey HN! I'm one of the folks behind Documenso (open-source document signing).

We spent years combining pdf-lib with a custom Rust signing library. It worked, but real-world PDFs kept finding edge cases.

Instead of waiting for a better library to appear, we wrote our own.

LibPDF:

- Lenient parsing with brute-force recovery (inspired by Apache PDFBox) - Digital signatures with no native bindings and full PAdES support - Incremental saves that preserve existing signatures - Encryption (AES-256, AES-128, RC4) - TTF/OTF font subsetting (ported from PDFBox's fontbox)

API inspired by pdf-lib.

Still in beta, but we use it in production at Documenso already. You might hit a few bugs that we haven't yet, if you do let us know!

Show HN: A minimal control primitive between impulse and action (OP Gap)

Hi HN,

I documented something I kept running into while debugging my own reactions under pressure.

There appears to be a tiny runtime gap between incoming signal (trigger) and outgoing action.

If that gap collapses, behavior executes automatically. If it stays open even briefly, explicit choice becomes available.

I formalized it as a minimal behavioral control primitive:

Origin → Signal → OP Gap → Zero Point → Operator Point → Choice → Action → Return

No beliefs, no mindset, no therapy framing. Just a control discontinuity observable in real time.

OP Gap itself doesn’t decide anything. It simply exposes a control surface. Without it: reflex. With it: authored action.

The model includes explicit failure modes: - gap collapse (autopilot) - operator unavailable - missing return (residual accumulation)

And a recovery mechanism (Return Frame).

I wrote a short technical book describing the closed loop.

I’m not trying to sell anything here — I’m interested in pressure-testing the architecture.

If you think this already exists under another name, or see structural flaws, I’d genuinely appreciate feedback.

Thanks.
