Show HN: Semble – Code search for agents that uses 98% fewer tokens than grep Hey HN! We (Stephan and Thomas) recently open-sourced Semble. We kept running into the same problem while using Claude Code on large codebases: when the agent can't find something directly, it falls back to grep, reading full files or launching subagents. This uses a lot of tokens, and often still misses the relevant code. There are existing tools for this, but they were either too slow to index on demand, needed API keys, or had poor retrieval quality. Semble is our solution for this. It combines static Model2Vec embeddings (using our latest static model: potion-code-16M) with BM25, fused via RRF and reranked with code-aware signals. Everything runs on CPU since there's no transformers involved. On our benchmark of ~1250 query/document pairs across 63 repos and 19 languages, it uses 98% fewer tokens than grep+read and reaches 99% of the retrieval quality of a 137M-parameter code-trained transformer, while being ~200x faster. Main features: - Token-efficient: 98% fewer tokens than grep+read - Fast: ~250ms to index a typical repo on our benchmark, ~1.5ms per query on CPU (very large repos may take longer) - Accurate: 0.854 NDCG@10, 99% of the best transformer setup we tested - MCP server: drop-in for Claude Code, Cursor, Codex, OpenCode - Zero config: no API keys, no GPU, no external services Install in Claude Code with: claude mcp add semble -s user -- uvx --from "semble[mcp]" semble Or check our README for other installation instructions, benchmarks, and methodology: Semble: https://ift.tt/Mo6hpQ3 Benchmarks: https://ift.tt/bLTiqDw Model: https://ift.tt/ArlPiTE Let us know if you have any feedback or questions! https://ift.tt/Mo6hpQ3 May 17, 2026 at 12:37PM

Show HN: Serene Bach – a Go weblog engine that runs as CGI or HTTP https://ift.tt/Qz2lYoD

Show HN: Serene Bach – a Go weblog engine that runs as CGI or HTTP I originally made Serene Bach in the 2000s as a weblog engine written in Perl CGI. I rebuilt it from scratch in Go as a single binary that can run either as a CGI program or as a normal HTTP server. I know CGI is generally considered legacy technology now, but I still rely on it for shared hosting. In this version, I added Markdown support, a responsive default theme, Open Graph image generation, and static output generation. It is still in beta, but the repository includes a Docker image published on GHCR, documentation, and a local quick start. I'd appreciate feedback from anyone interested in small self-hosted publishing tools, especially if you still care about shared hosting or CGI-style deployment. https://ift.tt/kzhutMS May 17, 2026 at 12:47AM

Show HN: Codiff, a local diff review tool https://ift.tt/Db9UE5g

Show HN: Codiff, a local diff review tool Nowadays I review a lot of code locally that was written by llms. I used to review my own code using git + delta. It started to feel limiting with the amount of code written by llms. When looking at a large diff on Friday I pointed an llm at diffs.com and trees.software and told it to build an app. It only took 16 minutes, is extremely fast for large diffs, beautiful and minimal. Today I polished it up and added all the features that I need. It has file filters, search, an llm walkthrough mode, and review comments that you can paste back into your llm. I will be using Codiff a lot, and can finally review the large diff from Friday that led me to build this If you like it, fork it! https://ift.tt/waIvpje May 17, 2026 at 02:30AM

Show HN: A Dark Cave – Minimalistic Graphics in the Age of AI Slop https://ift.tt/C2jreOh

Show HN: A Dark Cave – Minimalistic Graphics in the Age of AI Slop Almost a year ago I started building A Dark Cave, a dark text-based browser game. The game intentionally avoids visuals and embraces minimalism. I use only text, symbols, and sounds to create atmosphere and spark the player's imagination. From time to time, I think about adding graphics to my game, since it is one of the most common requests I get from players. I even made a post about what I call the AI Slop Temptation: https://ift.tt/tkAcK6e... From the comments, it seems that players prefer no graphics at all over AI-generated graphics, at least when they can recognize them as AI-generated. In my opinion, the growing abundance of easily available polished graphics means games will soon need main differentiators beyond visuals alone. Maybe it will be storytelling, atmosphere, creating emotions, personalization, nostalgia, or the ability to leave space for the player's imagination. When it becomes easy for every game to look good, what will be the things that actually make games great? What do you think? Also, I am grateful for any feedback about my game! https://ift.tt/JWbYvXN May 16, 2026 at 05:57AM

Show HN: Swpui, a TUI for case-aware search and replace Presentation article: https://ift.tt/yl4T3cD Codeberg mirror: https://ift.tt/ewi1IGM I've been working on a TUI to suit my terminal IDE workflow after I noticed the most promising alternative stopped being maintained and had too many bugs. The tool is implemented in Rust using the Ratatui library and focuses on being ergonomic, fast and provide case-aware replacement. The main feature I wanted to have is immediate feedback for the search query, which is also why I didn't stick with tools like fastmod and repgrep. As much as I hate VS Code now, I really enjoyed the search/replace experience with it and that's what I tried to emulate in swpui. Looking forward to your feedback! https://ift.tt/dzKn0EA May 16, 2026 at 05:47AM
