Show HN: Sfsym – Export Apple SF Symbols as Vector SVG/PDF/PNGhttps://github.com/yapstudios/sfsymI found myself reaching for SF Symbols' 'Copy Image As…' quite often during agentic design sessions, so I made a command-line tool that the agent can use by itself. It exports Apple SF Symbols as SVG, PDF, or PNG.The vector paths come directly from macOS's symbol renderer. Internally it reaches a private ivar on NSSymbolImageRep to get the CUINamedVectorGlyph, draws into a CGPDFContext, then walks the PDF content stream back out as SVG `d` commands. The output matches what the system draws, rather than an approximation traced from rasters.A few things about it:- Every subcommand accepts `--json`, and `sfsym schema` returns a machine-readable description of the whole CLI. - Symbol enumeration reads the OS's Assets.car BOM tree, so the list of 8,300+ names stays current with macOS updates without a version table in the binary. - Each SVG `` carries a `data-layer` attribute, so you can retheme in CSS without touching geometry.It's been saving me a bunch of clicking. Please let me know if

Ask HN: Agents Craving Contexthttps://news.ycombinator.com/item?id=47806038Hey, I was an early adopter of the Cursor IDE and pretty much installed it day 1 of it's public release. Like many I've been using LLMs to help accelerate the writing of code in my own company and side projects and have been quite optimistic and satisfied with the quality and experience of using the Cursor IDE chat -> composer -> agents to enhance the developer experience.However, recently it seems like there has been a shift in how agents work (I am mainly referring to using Cursor agents here but the seems to also apply for Claude Code). When I introduce a problem to the agent a while ago it used to just start writing code. I remember having to be explicit about selecting the files or even lines I wanted it to edit or generate code in, and be quite precise in supplying the LLM with the relevant context. These days I will write a similar prompt to what I would do before: "Refactor X.ts into separate files /utils/[module].ts using the /shared/utils directory as an example". (just a toy

Show HN: An MCP server that lets AI compose music on a hardware synthhttps://namirsab.dev/blog/teaching-claude-to-use-my-novation-circuit-tracks-part-3/Hey everyone! For the last 2 weeks, I've been working on an MCP server for my Novation Circuit Tracks (in case you don't know what it is, is just a little device to make electronic music). The idea is simple: I want an AI Agent to be able to make music using my gear, so I gave it tools to do it so I can just say something like "Build me a melodic ambient song with a dark atmosphere" and see the AI just do it.The whole project is Open Source (https://github.com/namirsab/circuit-tracks-tools) and I've written about it in my blog in case you want to go into more details. It is a fun project that includes reverse engineering of proprietary file formats.Would love to hear feedback, both from Circuit Track owners and just in general, what do you think about this idea? Have you tried something similar?

Show HN: Runtime security for AI agents(injection,tool abuse, data exfiltration)https://news.ycombinator.com/item?id=47799856Hi HNI’ve been working on an open-source project to explore a problem I keep running into with LLM systems in production:We give models the ability to call tools, access data, and make decisions… but we don’t have a real runtime security layer around them.So I built a system that acts as a control plane for AI behavior, not just infrastructure.GitHub: https://github.com/dshapi/AI-SPMWhat it doesThe system sits around an LLM pipeline and enforces decisions in real time:Detects and blocks prompt injection (including obfuscation attempts) Forces structured tool calls (no direct execution from the model) Validates tool usage against policies Prevents data leakage (PII / sensitive outputs) Streams all activity for detection + audit Architecture (high-level) Gateway layer for request control Context inspection (prompt analysis + normalization) Policy engine (using Open Policy Agent) Runtime enforcement (tool validation + sandboxing) Streaming pipeline (Apache Kafka + Apache Flink) Output fil

GitHub Copilot Chat 0.44.1 – Possible Malicious Releasehttps://news.ycombinator.com/item?id=47799186Hi All,Not really sure if this is the correct place to post this, but it looks like the VS Code release mechanism might have been compromised. The Visual Studio Marketplace has a release today of 0.44.1, but the github page shows no such release present (not even 0.44.0). Given the recent slew of supply chain hits I am a bit suspicious.

Ask HN: Opus 4.7 – is anyone measuring the real token cost on agentic tasks?https://news.ycombinator.com/item?id=47798959Shipped today. The benchmarks are real: 87.6% SWE-bench (from 80.8%), +13% on coding tasks, 3x more resolved production tasks on Rakuten-SWE-Bench. But there are a few changes that compound on each other for token consumption: a new tokenizer (1.0–1.35x more tokens for the same input depending on content type), xhigh effort mode that reasons longer per turn, and /ultrareview which spins up parallel agents for code review. The model is genuinely better. The question is whether "better reasoning on the same noisy context" is the right optimization. Coding agents still spend most of their budget exploring files they won't touch before doing anything useful — a smarter model doesn't fix that, it just does it more thoroughly. Curious what cost delta people are seeing on real codebases moving from 4.6 to 4.7, especially with the new effort levels. (I've been building in this space — vexp.dev is my attempt at the context side of the problem, happy to share more details if useful).

Show HN: Stack – the control plane for AI agentshttps://getstack.run/Dear diary, this is my story: I'd been sharing MCP configs with other devs at work a lot - templates in shared repos, credentials in Bitwarden, everyone cowboying their own env vars. That's a lot of manual wiring and lack of any real control, so there was already a problem statement forming in my mind. Then three weeks ago I was putting my kids to sleep and reading about Jensen Huang saying every company will run 100 agents per employee, and the math started mathing.That evening I kept thinking about what agents actually need to operate in the real world and eventually landed on the same answer as every spy movie ever: basically, a passport suitable for the mission and clever drop-off locations. So I built STACK. True story.- The passport: a signed JWT (EdDSA) that proves which agent is acting, who authorized it, and what it's allowed to do. Works offline - any service can verify it without calling STACK. Agents can delegate to sub-agents but the scope ever only narrows. Max 4 hops.- T

A brief generational overview of the tech industryhttps://news.ycombinator.com/item?id=47791293Modern consumer-focused technology, the finished products that we use in our day-to-day lives, is defined by the tech industry(AKA Big Tech, tech companies, the Internet, whatever you want to call it). Broadly speaking, this is the industry that has been the main driver of innovation in the past 50 years: producing wealth, increasing the standard of living, and improving human productivity. As of 2026, I can see this industry as having 2 clear generations of societal impact. I will list various tech companies and attempt to categorize them in generations. After that, I give my thoughts on the forthcoming third generation. Lastly, I will make a statement about subsequent generations as well as a closing remark.IBM - developed computers for industrial and personal use, this is a first generation tech company. Microsoft - developed the operating system and basic software used by billions, this is also a first generation tech company. Apple - developed novel tech products as well as softwa

Show HN: Springdrift – A persistent runtime for long-lived LLM agentshttps://github.com/seamus-brady/springdriftI wanted to share something that I have been working on since about 2019, in one form or another. Springdrift is a persistent, auditable runtime for long-lived agents written in Gleam on the BEAM. It is my attempt at filling in some of the gaps in agent development. It is designed to do all the things an agent like Openclaw can do (and more eventually), but it can diagnose its own errors and failures. It has a sophisticated safety metacognition system. It has a character that should not drift.It started out as a machine ethics prototype in Java and gradually morphed into a full agent runtime. All the intermediate variations worth saving are on my GitHub repo.I recall trying to explain to a mentor what exactly I was building. I found it difficult because there was no existing category for this kind of agent. It is not quite an assistant, it does more than run tasks. It is not quite an autonomous agent because even though it is autonomous, its autonomy is bounded. I kept falling back to

Show HN: Count Me In, a metronome that counts numbers for youhttps://labs.tiffzhang.com/count/Hey Hacker News! I recently made me own metronome app for my music practice because I often get lost in rhythm, and I thought it might be helpful to create metronome that counted actual numbers out loud for you to help me learn to count.So, for example, if you subdivide 4/4 into 16th notes, then the metronome would say:1e+a 2e+a 3e+a 4e+aOne thing where this has been especially helpful for me is that I added support for asymmetric rhythm patterns. In pop music, it's common for songs to use a 3-3-2 rhythm pattern with eighth notes. Even though this is usually written out in 4/4, in my app, if you set the rhythm to 8/8 and explicitly define the beat groups as 3+3+2, it will count this for you! This ends up being:1+a 2+a 3+You can see an example of what that looks like here! https://labs.tiffzhang.com/count/?bpm=100&ts=8-8&sub=2&vm=co...What do other people think? I'd love to hear if this helps anyone else with their music practice or if people have thoughts on things they'd like to see f
