Show HN: Homunculus – A self-rewriting Claude Code plugin https://ift.tt/uz29ikW

Show HN: Homunculus – A self-rewriting Claude Code plugin Homunculus is a Claude Code plugin that watches how you work and writes new capabilities into itself. If you keep doing something repeatedly—checking docs before API calls, running the same debug flow, formatting PRs a certain way—it notices and offers to automate it. Accept, and it writes a new markdown file into its own structure. The plugin literally changes based on what you do. It can create: Commands (explicit shortcuts) Skills (context-triggered behaviors) Subagents (specialists for specific problem domains) Hooks (event-driven, like "run tests when these files change") What actually works (v0.1): Commands are deterministic. Skills are probabilistic—they fire when Claude decides they're relevant, maybe 50-80% of the time. It's an experiment in making LLM tooling adaptive rather than static. State stored in .claude/homunculus/. Each project gets its own instance. https://ift.tt/mNBMOv8 January 19, 2026 at 11:23PM

Show HN: Subth.ink – write something and see how many others wrote the same https://ift.tt/e87bJPw

Show HN: Subth.ink – write something and see how many others wrote the same Hey HN, this is a small Haskell learning project that I wanted to share. It's just a website where you can see how many people write the exact same text as you (thought it was a fun idea). It's built using Scotty, SQLite, Redis and Caddy. Currently it's running in a small DigitalOcean droplet (1 Gb RAM). Using Haskell for web development (specifically with Scotty) was slightly easier than I thought, but still a relatively hard task compared to other languages. One of my main friction points was Haskell's multiple string-like types: String, Text (& lazy), ByteString (& lazy), and each library choosing to consume a different one amongst these. There is also a soft requirement to learn monad transformers (e.g. to understand what liftIO is doing) which made the initial development more difficult. https://subth.ink/ January 20, 2026 at 12:04AM

Show HN: Xenia – A monospaced font built with a custom Python engine https://ift.tt/wyX69Pl

Show HN: Xenia – A monospaced font built with a custom Python engine I'm an engineer who spent the last year fixing everything I hated about monofonts (especially that double-story 'a'). I built a custom Python-based procedural engine to generate the weights because I wanted more logical control over the geometry. It currently has 700+ glyphs and deep math support. Regular weight is free for the community. I'm releasing more weights based on interest. https://ift.tt/y8iUAxb January 18, 2026 at 04:09PM

Show HN: ChunkHound, a local-first tool for understanding large codebases https://ift.tt/t4BhIci

Show HN: ChunkHound, a local-first tool for understanding large codebases ChunkHound’s goal is simple: local-first codebase intelligence that helps you pull deep, core-dev-level insights on demand, generate always-up-to-date docs, and scale from small repos to enterprise monorepos — while staying free + open source and provider-agnostic (VoyageAI / OpenAI / Qwen3, Anthropic / OpenAI / Gemini / Grok, and more). I’d love your feedback — and if you have, thank you for being part of the journey! https://ift.tt/m4cpSKj January 18, 2026 at 02:33AM

Show HN: UAIP Protocol – Secure settlement layer for autonomous AI agents https://ift.tt/mBsrWkS

Show HN: UAIP Protocol – Secure settlement layer for autonomous AI agents Hi HN! Creator here. I built UAIP (Universal Agent Interoperability Protocol) - infrastructure that enables AI agents from different companies (OpenAI, Anthropic, Microsoft) to securely transact with each other. The Problem: As AI agents become autonomous economic actors, they need: Cryptographic identity (not just API keys) Secure payment rails for cross-company transactions Automated compliance (EU AI Act, SOC2, GDPR) Forensic audit trails The Solution: 5-layer security stack combining: Zero-Knowledge Proofs (Schnorr/Curve25519) for identity Multi-chain settlement (USDC on Base, Solana, Ethereum) RAG-based compliance auditing (Llama-3-Legal) Ed25519 signatures for non-repudiation Complete audit logging Technical Stack: Backend: Python, FastAPI, SQLite (WAL mode) Cryptography: NaCl, custom ZK-proof implementation Blockchain: Web3.py for multi-chain support Compliance: RAG with retrieval-augmented generation Use Case: GPT agent pays Claude agent for data analysis: Both prove identity via ZK-proofs Transaction checked for compliance Settled in USDC on Base (<$0.01 fee) Complete audit trail generated Why blockchain: Neutral settlement layer (no single company controls it) Instant microtransactions (traditional payments don't work for $0.01-$10) Programmable escrow (smart contracts) Verifiable computation (on-chain proofs) Open source (FSL-1.1-Apache-2.0). Built over the last few months after hitting these problems in AI automation work. Happy to answer technical questions!

Show HN: Minikv – Distributed key-value and object store in Rust (Raft, S3 API) https://ift.tt/PxrfXei

Show HN: Minikv – Distributed key-value and object store in Rust (Raft, S3 API) Hi HN, I’m releasing minikv, a distributed key-value and object store in Rust. What is minikv? minikv is an open-source, distributed storage engine built for learning, experimentation, and self-hosted setups. It combines a strongly-consistent key-value database (Raft), S3-compatible object storage, and basic multi-tenancy. I started minikv as a learning project about distributed systems, and it grew into something production-ready and fun to extend. Features/highlights: - Raft consensus with automatic failover and sharding - S3-compatible HTTP API (plus REST/gRPC APIs) - Pluggable storage backends: in-memory, RocksDB, Sled - Multi-tenant: per-tenant namespaces, role-based access, quotas, and audit - Metrics (Prometheus), TLS, JWT-based API keys - Easy to deploy (single binary, works with Docker/Kubernetes) Quick demo (single node): git clone https://ift.tt/TtBE3ID cd minikv cargo run --release -- --config config.example.toml curl localhost:8080/health/ready # S3 upload + read curl -X PUT localhost:8080/s3/mybucket/hello -d "hi HN" curl localhost:8080/s3/mybucket/hello Docs, cluster setup, and architecture details are in the repo. I’d love to hear feedback, questions, ideas, or your stories running distributed infra in Rust!
