Show HN: Agent Composer – Create your own AI rocket scientist agent

Hey HN! We launched a thing today, and built a cool demo that I'm excited to share with the community.

This tool creates AI agents easily and can handle some really technically complex work. I whipped up this rocket scientist agent in our tool in 10 minutes. I asked a couple of aerospace engineer friends what they thought, and they found it useful for their real work, which is why I want to share it here. Here's the demo https://demo.contextual.ai/ and an overview https://docs.contextual.ai/examples/rocket_science

Would love to see technical HN folks and their experience with our tool (and whether it would be useful in your work). Happy to go deep on architecture, retrieval strategies, and lessons learned.

Show HN: Runtime AI safety via a continuous "constraint strain" score

Show HN: Runtime AI safety via a continuous "constraint strain" score

Hi HN — I’ve been working on a small open-source experiment around runtime AI safety.

The idea is to treat AI risk not as a binary “safe/unsafe” state or post-hoc failure analysis, but as accumulated constraint strain over time — similar to how engineers think about mechanical stress.

The project defines a simple, model-agnostic signal (GV) and a lightweight runtime monitor (Sentinel) that classifies risk into bands (green/yellow/red) and suggests interventions (alert, throttle, human review).

This is an early MVP — intentionally minimal — meant to explore whether continuous, quantitative safety signals are useful before failures occur, especially for agents and LLM-based systems in production.

I’d really appreciate feedback, criticism, or pointers to prior art I should study. Repo: https://github.com/willshacklett/gvai-safety-systems

Ask HN: What are you optimistic about in the age of AI?

As a senior-almost-staff engineer just having turned 30, I feel pretty pessimistic about AI and how much it's going to affect the lives and careers of myself and my peers. I see people optimistic about AI for how it can impact and improve society but also at a personal level for their own careers. What should I be looking towards to not despair for the future?

Show HN: DocEndorse – An AI assistant that runs your e-sign workflow in chat

DocEndorse is an AI-powered e-signature assistant that lets you prepare, send, track, and follow up on documents through natural language instead of forms and drag-and-drop editors.

You can tell it what you want (“Send this NDA to John for signature”), and it will: • Find the right document and contacts • Detect and place signing fields • Assign signer roles • Suggest titles and messages • Send requests via email, SMS, WhatsApp, or Microsoft Teams • Track status and automatically follow up with signers

It supports the full e-signature lifecycle: self-signing, sending requests, templates, reminders, resends, and real-time status updates. Follow-ups are generated automatically with tone and timing adjusted based on progress.

Show HN: A 4.8MB native iOS voice transcriber built with SwiftUI

Hey HN,

I wanted to share a project I’ve been working on called Convoxa. It’s a native iOS transcriber/summarizer. I had two main goals: keep it efficient and keep it private.

THE TECH STACK

100% Swift & SwiftUI: No heavy cross-platform wrappers or bloated dependencies.

Binary Size: The final build is only 4.8 MB.

Transcription: Uses Apple's latest speech APIs for maximum privacy and efficiency.

THE CHALLENGE: BYPASSING THE 4K CONTEXT LIMIT

The biggest technical hurdle was working with Apple’s foundation models. The default context window is capped at 4096 tokens, which is practically useless for anything over a 10-minute meeting transcript.

I ended up building a recursive chunking method to "feed" the model long-form data without losing the global context of the conversation. I use a sliding window approach where each chunk's summary informs the next, ensuring the final output doesn't "hallucinate" at the seams where the chunks meet. It’s now stable enough for long-form audio while remaining entirely on-device for supported hardware.

PRIVACY & AI MODES

On-Device: (Apple Intelligence required) - Total local processing.

Cloud: With reasoning for intelligent insights (Zero Data Retention).

I’m currently in the pre-order phase (out on Feb 3rd) and would love to get some feedback from this community on the performance and the chunking logic.

Show HN: We ship Flutter app updates without resubmitting on AppStore

Hi HN,

We built Stac a server driven UI framework for Flutter.

The idea is simple: instead of shipping a new app release for every UI change, the app renders UI from JSON delivered by the backend. This allows teams to update layouts, experiment with flows, and roll out changes instantly while keeping Flutter’s performance and type safety.

Stac is open source and already used in production by startups and enterprise teams for things like:

Feature flags and experiments

Faster iteration on UI without app store delays

Sharing UI logic across multiple Flutter apps

We are currently working on better tooling, validation, and a hosted solution for managing and deploying UI schemas.

Would love feedback from people who have built or evaluated server driven UI systems. What tradeoffs or pitfalls should we be thinking more about?
