[API/SDK] Show HN: Open-agent-SDK – Claude Code's internals, extracted and open-sourced Claude Code's source map leaked last month. Instead of just reading it, I fed the entire source into Claude Code itself and asked it to extract the core agent loop logic.<p>The result: open-agent-sdk — a drop-in replacement for claude-agent-sdk that's fully open source and doesn't spawn a CLI subprocess.<p>Why this matters if you've built with claude-agent-sdk:<p>claude-agent-sdk is just a thin wrapper around the Claude Code binary. It works, but it's a black box — when something breaks, you're stuck.<p>Every query creates a new Claude Code process. That's fine on a laptop, not fine when you're running thousands of concurrent agents in the cloud.<p>What open-agent-sdk does differently:<p>Pure function calls, no CLI process spawning — cloud-native from day one Fully compatible interface with claude-agent-sdk — swap the package name, done<p>MIT licensed — fork it, patch it, make it yours<p>→ <a href="https://github.com/codeany-ai/open-agent-sdk-typescript" rel="nofollow">https://github.com/codeany-ai/open-agent-sdk-typescript</a>

SolveSpace (open source 2D/3D CAD) working on Windows 2000 (2025)
Hacker News (score: 25)[Other] SolveSpace (open source 2D/3D CAD) working on Windows 2000 (2025) SolveSpace just became "officially" available for the Web (<a href="https://news.ycombinator.com/item?id=47586614">https://news.ycombinator.com/item?id=47586614</a>), it is also officially supported on Windows (Vista-11), Linux and macOS.<p>However with a little effort it also compiles for and runs on Windows 2000. Here it is:<p><a href="https://github.com/solvespace/solvespace/issues/1036#issuecomment-3405830198" rel="nofollow">https://github.com/solvespace/solvespace/issues/1036#issueco...</a><p>So it runs on all the majour platforms from the last 26 years (excluding MacOS 9).
Show HN: Real-time dashboard for Claude Code agent teams
Hacker News (score: 67)[Monitoring/Observability] Show HN: Real-time dashboard for Claude Code agent teams This project (Agents Observe) started as an exploration into building automation harnesses around claude code. I needed a way to see exactly what teams of agents were doing in realtime and to filter and search their output.<p>A few interesting learnings from building and using this:<p>- Claude code hooks are blocking - performance degrades rapidly if you have a lot of plugins that use hooks<p>- Hooks provide a lot more useful info than OTEL data<p>- Claude's jsonl files provide the full picture<p>- Lifecycle management of MCP processes started by plugins is a bit kludgy at best<p>The biggest takeaway is how much of a difference it made in claude performance when I switched to background (fire and forget) hooks and removed all other plugins. It's easy to forget how many claude plugins I've installed and how they effect performance.<p>The Agents Observe plugin uses docker to start the API and dashboard service. This is a pattern I'd love to see used more often for security (think Axios hack) reasons. The tricky bit was handling process management across multiple claude instances - the solution was to have the server track active connections then auto shut itself down when not in use. Then the plugin spins it back up when a new session is started.<p>This tool has been incredibly useful for my own daily workflow. Enjoy!

Show HN: Claude Code rewritten as a bash script

Show HN: How This Graybeard Built the Fastest and Freest Postgres BM25 Search
Hacker News (score: 25)[Other] Show HN: How This Graybeard Built the Fastest and Freest Postgres BM25 Search Last summer we faced a conundrum at my company, Tiger Data, a Postgres cloud vendor whose main business is in timeseries data. We were trying to grow our business towards emerging AI-centric workloads and wanted to provide a state-of-the-art hybrid search stack in Postgres. We'd already built pgvectorscale in house with the goal of scaling semantic search beyond pgvector's main memory limitations. We just needed a scalable ranked keyword search solution too.<p>The problem: core Postgres doesn't provide this; the leading Postgres BM25 extension, ParadeDB, is guarded behind AGPL; developing our own extension appeared daunting. We'd need a small team of sharp engineers and 6-12 months, I figured. And we'd probably still fall short of the performance of a mature system like Parade/Tantivy.<p>Or would we? I'd be experimenting long enough with AI-boosted development at that point to realize that with the latest tools (Claude Code + Opus) and an experienced hand (I've been working in database systems internals for 25 years now), the old time estimates pretty much go out the window.<p>I told our CTO I thought I could solo the project in one quarter. This raised some eyebrows.<p>It did take a little more time than that (two quarters), and we got some real help from the community (amazing!) after open-sourcing the pre-release. But I'm thrilled/exhausted today to share that pg_textsearch v1.0 is freely available via open source (Postgres license), on Tiger Data cloud, and hopefully soon, a hyperscalar near you:<p><a href="https://github.com/timescale/pg_textsearch" rel="nofollow">https://github.com/timescale/pg_textsearch</a><p>In the blog post accompanying the release, I overview the architecture and present benchmark results using MS-MARCO. To my surprise, we were not only able to meet Parade/Tantivy's query performance, but exceed it substantially, measuring a 4.7x advantage on query throughput at scale:<p><a href="https://www.tigerdata.com/blog/pg-textsearch-bm25-full-text-search-postgres" rel="nofollow">https://www.tigerdata.com/blog/pg-textsearch-bm25-full-text-...</a><p>It's exciting (and, to be honest, a little unnerving) to see a field I've spent so much time toiling in change so quickly in ways that enable us to be more ambitious in our technical objectives. Technical moats are moats no longer.<p>The benchmark scripts and methodology are available in the github repo. Happy to answer any questions in the thread.<p>Thanks,<p>TJ (tj@tigerdata.com)
