Show HN: Sentinel – Zero-trust governance for AI Agents

Hi HN,

I’m a software engineer and I’ve been building agentic workflows lately. Like many of you, I got concerned about giving LLMs "write access" to tools. Whether it's a payment API, a database deletion, or a simple email send, the risk of a hallucination causing a $5k mistake is real.

I wanted a way to keep a human in the loop without rewriting my entire agent logic every time. So I built Sentinel.

It’s a lightweight Python layer that wraps any tool/function. The key principles I focused on:

Fail-secure by default: If the rules engine or the network fails, the action is blocked. Most systems fail-open, which is a nightmare for security.

Zero-trust Decorator: You just add @protect to your functions. It’s agnostic to the framework (works with LangChain, CrewAI, or raw OpenAI calls).

Semantic Anomaly Detection: Beyond static JSON rules (like "max $100"), it uses a Z-score analysis of historical audit logs to flag unusual behavior—like an agent suddenly trying to call a function 100 times in a minute.

Context-Aware Approvals: The approver sees exactly what the AI saw (the state before the action) to make an informed decision.

It’s open source (MIT) and just launched on PyPI: pip install agentic-sentinel

I’d love to hear your thoughts on the "Fail-secure" approach and how you guys are currently handling AI tool governance in production. I'm here to answer any questions!

Show HN: 500-cycle runtime test for long-horizon LLM coherence

We ran a 500-cycle benchmark to test long-horizon reasoning stability in large language models — not just output quality, but whether a model can maintain coherent identity and logic across hundreds of recursive reasoning steps.

This is part of our SIGMA Runtime project — a cognitive control layer that runs on top of any LLM and tracks drift, coherence, and identity persistence in real time.

---

Why we did this

Most LLM evals measure short reasoning spans — 1-10 turns. But when a model is asked to sustain a line of reasoning over hundreds of steps, subtle feedback effects appear:

- Semantic drift: meaning slowly shifts as text compounds. - Crystallization: the model locks into repeating its own phrasing or style. - Identity loss: the “speaker” loses internal consistency.

We wanted to see whether it’s possible to prevent these effects at runtime, without retraining or prompt resets.

---

What’s new here

We replaced the older ACE anti-crystallization layer with a new system called AEP (Adaptive Entropy Protocol) — a real-time regulator that injects controlled entropy into model outputs.

AEP tracks three internal metrics: - TI — Terminological Isometry (consistency of key concepts) - SDC — Semantic Drift Coefficient (meaning variation rate) - L/N — Logic-to-Noise ratio (logical density vs surface variation)

When the model becomes too stable (repetition, rigid phrasing), AEP adds micro-perturbations to restore variation. When it drifts too far, it dampens entropy back into equilibrium.

---

How we tested it

- 500 reasoning cycles per model (OpenAI GPT-5.2 & Gemini-3-Flash Preview) - Every 50th cycle = a Rib Point that compresses and verifies the last 49 steps - Continuous telemetry from the runtime (coherence, drift, entropy) - Identity: same synthetic agent (“LEO”, AI architect/cognitive scientist)

---

What happened

Both models completed all 500 cycles without identity loss or semantic collapse. Entropy modulation increased lexical variety, while keeping reasoning trajectories coherent.

When truncations occurred (Gemini API), the runtime reconstructed missing context using prior compression checkpoints.

---

Visual results

---

Takeaway

- Entropy can be regulated, not just randomized. - LLMs can maintain self-consistent reasoning over hundreds of cycles when given runtime feedback. - Structural stability (coherence, terminology, logic) doesn’t require retraining — only a dynamic control layer.

Show HN: Make custom ASCII art t-shirts from your terminal

I wanted to build my first CLI app and was inspired by terminal.shop (the coffee one). Figured if you can order coffee from your terminal, you should be able to order a t-shirt too.

how it works: you describe what you want, it generates ASCII art, shows you a mockup on an actual shirt, and you can check out right there.

  pip install ascii-tee

  ascii-tee "sunflower"
Stack:

- CLI: Typer + Rich for the interactive flow (prompts, spinners, panels)

  - ASCII generation: Claude API, with a system prompt tuned for a 40×30 character canvas that prints well

  - Preview: Pillow composites the ASCII (rendered with JetBrains Mono) onto a shirt mockup template

  - Terminal images: Detects iTerm2/Kitty/WezTerm for native inline images, falls back to timg or chafa, then browser

  - Backend: Cloudflare Workers handling API calls

  - Checkout: Stripe, with the preview image shown on the payment page

  - Fulfillment: Printful prints and ships (Bella+Canvas 3001)
First time building something like this so would appreciate any feedback.

Show HN: Helping my band rehearse remotely without installing a DAW

Show HN: Helping my band rehearse remotely without installing a DAW

Hey everyone,

I built an app called SingTogether because I was tired of trying to get my bandmates to install complex DAWs just to practice over a demo. I wanted something that works instantly in the browser.

It’s designed to help bands and choirs practice and collaborate using their own multitracks.

The Main Use Cases:

1. Rehearsing a Song

The Problem: Sending MP3s back and forth is messy, and you can't isolate instruments.

The Solution: The band leader uploads multitracks to the app and sends a link. The team opens it (on phone or desktop) and can practice using standard tools like solo, mute, pan, and volume faders to isolate their specific part.

2. Asynchronous Jamming

The Problem: We want to experiment with ideas but can't meet up.

The Solution: A band member adds a base track (instrumental or vocal). They send the invite link, and other members can record a vocal or instrumental part straight from the browser. Everyone can listen to the layered contributions immediately.

I'd love for you to try it out and let me know what features would make your practice sessions easier.
