Cairn

Git-native tasks your AI agents and team actually share

What it does

Cairn is a cross-platform desktop app for tracking tasks as Markdown files in your repo. No database. It serves the same tasks to your AI agents over MCP and to you over a clean UI, so an agent and a human always see the same state. The difference: agents can't fake "done." Every task carries checks like go test/.... cairn runs them on close and refuses to close if any fail. Git owns the history, every write is signed, and agents hand off for review. Open source.

A repo-native task graph as plain Markdown files, served to AI agents over MCP and to humans over a clean web UI . - ShahramMebashar/cairn

Repo-native task management. One task graph your agents and you share. cairn is a task graph that lives as Markdown files in your repository . A single Go binary ( cairn ) serves it to AI agents over MCP and to humans over a clean web UI. One source of truth: the files. One rule-set: internal/task . No database. make build # -> bin/cairn cairn web --repo . # open the board in your browser Then open the Connect page and wire up an agent in one click, or do it by hand: claude mcp add cairn -- " $( pwd ) /bin/cairn " serve --actor agent:claude --repo " $( pwd ) " Full walkthrough: Installation → Quickstart . One-click connect for Claude Code, Cursor, Codex, Windsurf, OpenCode, Kilo Code, and…from github.com

  • Git for AI AgentsMay 2026 · github.com · ▲129

    hi guys. been working on something i think is fundamentally missing in today's workflow with ai agents. vcs. i find myself struggling with questions that agents can't answer like "why did you do it?", "when did u delete this folder? why?", etc. or trying to /rewind (after a /compact...) or basically `bisect` to find when and why something was done by the agent in the current / previous session. just like git did for code, i think we are the same core capabilities with ai agents so... i developed an open source solution for that (currently supporting claude code) would love to…

  • A Karpathy-style LLM wiki your agents maintain (Markdown and Git)Apr 2026 · github.com · ▲260

    I shipped a wiki layer for AI agents that uses markdown + git as the source of truth, with a bleve (BM25) + SQLite index on top. No vector or graph db yet. It runs locally in ~/.wuphf/wiki/ and you can git clone it out if you want to take your knowledge with you. The shape is the one Karpathy has been circling for a while: an LLM-native knowledge substrate that agents both read from and write into, so context compounds across sessions rather than getting re-pasted every morning. Most implementations of that idea land on Postgres, pgvector, Neo4j, Kafka, and a dashboard. I…

  • Sphinx – a hook that quizzes you on your AI's code before shipping5d ago · sphinx-six-theta.vercel.app · ▲252

    A Git hook for agent-assisted development. Before your agent’s code ships, Sphinx asks you a question about what it actually does.

  • GitAgent by LyzrMar 2026 · gitagent.sh · ▲231

    Hey HN, We built GitAgent — a git-native, framework-agnostic open standard for defining AI agents. The idea is simple: your repo IS the agent. npx @open-gitagent/gitagent@latest run -r https://github.com/shreyas-lyzr/architect -a claude That one command clones the repo, reads agent.yaml + SOUL.md + skills/, and launches it with Claude Code. Switch `-a openai` or `-a lyzr` to run the same agent on a different framework. No code changes. Goal: is keep the gitagent as a open standard ledger for an AI Agent in a VM, with versioned memories, skills etc. An agent is…

  • Parallel CodeMar 2026 · parallelcode.app · ▲159

    I kept running into a structural problem with AI coding tools. You try one agent. It makes changes. You try another. Now you're manually diffing branches and cleaning up experimental commits. The tools are powerful, but the workflow isn’t designed for comparison. So I built Parallel Code. It runs Claude Code, Codex, and Gemini CLI natively (no API wrapper, no feature abstraction), but isolates each agent in: its own terminal its own Git worktree its own feature branch The workflow becomes: Spawn N worktrees Assign one AI agent per worktree Let them implement independently Compare diffs Merge…

  • Talanoa▲346

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  • Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  • Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
