AI coding session context lost when switching tools

“Show HN: Needle: We Distilled Gemini Tool Calling into a 26M Model Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are o”

“Show HN: Total Recall – write-gated memory for Claude Code built this because I got tired of re-teaching Claude Code the same context every session. Preferences, decisions, “we already tried X,” “don’t touch this file,” etc. After a few days it starts to feel like onboarding the same coworker every morning. Most “agent memory” tools auto-save everything. That feels good briefly, then memory turns into a junk drawer and retrieval gets noisy. Total Recall takes the opposite approach: a write gate.”

“Show HN: Mesa – A collaborative canvas IDE built for agent-first development Hi HN - I'm Ryan a product designer who codes, and I built Mesa. Current IDEs feel wrong for the type of development being done now - the focus is still on files. Mesa puts the focus on the full workflow: your agent, terminal, browser, and files all live as equal nodes on a canvas with full multiplayer support. (think figma but for code) I was tired of the overhead of switching windows, tabs, and terminals across m”

“Ask HN: $50 monthly budget, which coding models would you recommend now? I currently have a claude pro monthly subscription ($20) which I use for coding. It's been useful but I'm fatigued from optimising my work around it's session limits. There are so many choices and providers out there today but hard to get a good signal about what's good. I'm not looking for another Opus-level model but something reliable enough that it can follow TDD well.”

“Ask HN: How do you cope with the broken rythm of agentic coding? I used to seek focus and concentration while coding. It was not always easy to reach this flow state but I knew it was possible. I am now using agentic coding quite a lot. The honeymoon is finishing and I am starting to dislike some facets of it. I think the main setback is the rythm. Writing some specs/prompts, launching the agent, confirming quite atomic actions and waiting 10 to 30 seconds until the next question/confi”

“Show HN: Hydron – Hardware-aware coding agent Hi HN, this is Prashant from H2Loop. Embedded engineers that we work with were annoyed that generic AI tools hallucinated register addresses, generated code for peripherals that don't exist on the chip and mixed up timer quirks between similar platforms like STM32F4 and F7. The code looks clean but it just won't boot. This made them go back to the datasheet every time. So we built Hydron, an AI tool that writes datasheet-grounded code for y”

“Show HN: Dap-mux – Connect your editor and REPL to the same debug session I have been coding over four decades, in many languages, on many projects (including Firefox, Final Cut Pro, the Newton, and Fullwrite Professional if you can remember that far back; all these using my dead-name ). I wrote something small and simple to scratch an itch. It's the UNIX philosophy: small one-trick ponies , each *really* good at their one trick, then the user can hook them together to solve actual problems”

“Show HN: Unpack – a lightweight way to steer Codex/Claude with phased docs I've been using LLMs for long discovery and research chats (papers, repos, best practices), then distilling that into phased markdown (build plan + tests), then handing those phases to Codex/Claude to implement and test phase by phase. The annoying part was always the distillation and keeping docs and architecture current, so I built Unpack: a lightweight GitHub template plus docs structure and a few commands th”

“Show HN: OpenGem – A Load-Balanced Gemini API Proxy (No API Key Required) Hi HN! I built OpenGem, an open-source, load-balanced proxy for the Gemini API that requires absolutely no paid API keys. GitHub: https://github.com/arifozgun/OpenGem The Context: Like many developers, I was constantly hitting 429 Quota Exceeded errors while building AI agents and processing large payloads on free tiers. I wanted to build freely without calculating API costs for every test request. How ”

“Show HN: ContextVault – Shared memory layer for your AI and your team Hi HN, I'm Kevin. I built ContextVault because I kept running into the same problem with AI tools. Every project accumulated prompts, coding conventions, architectural decisions, examples, and other pieces of context that made the models significantly more useful. The problem was that this information quickly became fragmented. Some lived in ChatGPT Projects, some in Claude, some in Markdown files, some in internal docume”
