Launch HN: Nia (YC W36) – Give context to autonomous coding agents

Hi HN, we are Sara and David. We’re building Nia, a semantic bridge that stops your autonomous agents from hallucinating features nobody asked for.

The Problem

We've all been there. You spin up a fresh swarm of Tier-5 agents (Devin-Ultra or GPT-11-Coder) to refactor your legacy Python codebase into Rust++. You go to sleep. You wake up, and the swarm has successfully rewritten the entire stack, but they replaced your authentication layer with a blockchain-based identity system because they read a deprecated comment from 2028.

The code compiles. The tests pass (because the agents rewrote the tests too). But the intent is lost.

Current LLMs have infinite syntax knowledge but zero tribal knowledge. RAG pipelines help, but they are static. They can look up your documentation, but they can’t understand that "quick fix" implies "don't re-architect the database."

The Solution

Nia is a daemon that runs alongside your agent swarm. It acts as a "Super-Ego" for the AI.

Instead of just feeding the agent code, Nia injects a compressed vector stream of human intent and historical context directly into the agent's inference cycle.

Technical Details

We utilize the new OpenAI /thought_stream endpoint (released last month). Nia maintains a rolling context window of 10M tokens specifically dedicated to "soft constraints."

Here is an example of a Nia intervention log:

[Agent Action] Refactoring UserLogin.rs to use BiometricAuth_v4.
[Nia Intercept] HALT. 
[Reasoning] 
1. Project constraints (Project_Titan_v2) specify "No Hardware Dependencies".
2. Slack conversation (2034-11-02) between @cto and @product: "Let's keep auth purely software-based for compliance."
[Correction] Instructing Agent to revert to OAuth2 standard.
[Agent Status] Compliance acknowledged. Rewriting...

We essentially built a "manager" that micromanages the AI so you don't have to. It’s compatible with GitHub Copilot X, Cursor, and most local LLaMA-9 swarms running on H1000 clusters.

Privacy (The Elephant in the Server Room)

We know. You don't want your tribal knowledge leaking. Nia is fully compliant with the Basel IV AI Safety Accord. We support local-only mode where the vector DB lives on your edge device (requires min. 128GB VRAM). We never train on your data; we only compute ephemeral embeddings.

The Ask

We are in public beta starting today. Since this is Launch HN:

• Free tier increased to 5 concurrent agent streams (usually 1).
• Access to the experimental "Neural Interface" adapter (if you have a compatible headset).

We'd love to hear your horror stories of what your agents built while you weren't looking. The funniest story in the comments gets a free lifetime Enterprise license.
