   Peek▲404

   Hey HN, My cofounder and I have gotten tired of CC ignoring our markdown files so we spent 4 days and built a plugin that automatically steers CC based on our previous sessions. The problem is usually post plan-mode. What we've tried: Heavily use plan mode (works great) CLAUDE.md, AGENTS.md, MEMORY.md Local context folder (upkeep is a pain) Cursor rules (for Cursor) claude-mem (OSS) -> does session continuity, not steering We use fusion search to find your CC steering corrections. - user prompt embeddings + bm25 - correction embeddings + bm25 - time decay - target query embeddings -…

    SpacePigeon▲93

    I switch between a few different “modes” on my Mac every day (work, coding, meetings, personal stuff). Each time I’d end up reopening the same apps and dragging all the windows back into the right Spaces. Super repetitive and honestly kind of annoying. So over the past few weeks I hacked together a small open-source tool called SpacePigeon that basically remembers your whole workspace and puts everything back where it was. Things it can do: Save your current layout (apps + windows + Spaces) Restore it with one click or a hotkey Keep separate presets (like “Work”, “Coding”, “Meetings” etc.)…

    I made a customizable iOS browser for minimalists and myself▲226

    Hello HN! So early this year I decided to build an iOS browser offering a large range of customization options, to accommodate anyone’s usage and visual preferences. Been using it as my default browser for 6 months and not looking back. On first launch it looks and behaves a bit like Safari, but to give you an idea, here are the various ways I customized it on my phone. - More screen real estate for the webpage, less for the toolbar. - A compact toolbar containing only the buttons for actions I use the most: new tab, close tab, open tab list. Since I use them hundred times a day, I need them…
