cli
Google Workspace CLI — one command-line tool for Drive, Gmail, Calendar, Sheets, Docs, Chat, Admin, and more. Dynamically built from Google Discovery Service. Includes AI agent skills. (by googleworkspace)
Project mention: Fired by Google for Creating the Google Workspace CLI | news.ycombinator.com | 2026-06-23I did a bit of digging and the disclaimer about it not being an officially supported Google project was there from the start. There was briefly a logo that used Google colors but it seems extreme to fire someone over such a small misstep[0]. My guess is either HR didn't tell him the real reason for his firing or he's not telling the whole story.

moltis
A secure persistent personal agent server in Rust. One binary, sandboxed execution, multi-provider LLMs, voice, memory, Telegram, WhatsApp, Discord, Teams, and MCP tools. Secure by design, runs on your hardware.
Project mention: OpenClaw Is a Security Nightmare Dressed Up as a Daydream | news.ycombinator.com | 2026-03-22I'm on my 3rd "claw" variant (currently https://github.com/moltis-org/moltis). I had the same issues you had. Moltis is better (at the moment).

Project mention: Most AI dev tools assume you have a repo. Ops engineers have a broken node and a 3am page. | dev.to | 2026-06-18
What I'm working on I've been building something along these lines called aish — an AI shell runtime that sits inside your real terminal and focuses on Linux ops troubleshooting. The core loop: you run commands normally. When something fails, you ask the AI. It uses the last command, exit code, output, and node context to help diagnose. It warns before risky operations. It stays out of the way when you don't need it. It's not glamorous work. Most of the problems it deals with are things like systemd unit failures, broken package repos, permission issues, disk pressure, and the eternal "why won't nginx start." The kind of stuff that isn't exciting until it's your problem at 2am. Currently at v0.3.4 (recently rewrote the core from Python to Rust, which is a story for another post involving haunted PTYs). If you spend time debugging Linux boxes and have opinions about what would actually help in that workflow, I'd genuinely like to hear them — either here or on GitHub.

bitrouter
The self-improving LLM router that optimize your agentic workflows with every runs, works with any harnesses, any models, any loops.
Project mention: Ask HN: What is your AI harness that lets you switch LLM models easily? | news.ycombinator.com | 2026-07-07I would recommend just connect your whatever you used or built to a LLM gateway & router to use any models without management complexity.
I built BitRouter(https://github.com/bitrouter/bitrouter), open-sourced, 0 markup for all models, free BYOK/subscription, and works with any harnesses out of the box

wirken
The switchboard for the agent era. Per-channel isolation, encrypted credential vault, per-session hash-chained audit log. Single static Rust binary.

Project mention: I Let an AI Agent Supervisor Run Unattended for 19 Days. Here's What the Telemetry Says. | dev.to | 2026-04-16
Batty is supervised agent execution for software teams. It runs agents (Claude Code, Codex, Aider) inside tmux panes, tracks work on a markdown kanban board, gates merges behind a real test run, and surfaces escalations to a human via Discord. The supervisor itself is a Rust daemon. It's open source: github.com/battysh/batty.

run.dev
Run.dev is an AI-native local development environment built in Rust. It manages all your services from one TUI dashboard — automatic .local domains with HTTPS, SNI-based reverse proxy, live CPU/memory stats, and Claude Code integration for crash diagnosis and live debugging. One binary. Zero config files.
Project mention: Run.dev – A single Rust binary that replaces MAMP, Nginx for local dev | news.ycombinator.com | 2026-03-16GitHub: https://github.com/danieltamas/run.dev
Written in Rust with tokio, ratatui, and rustls. MIT licensed. macOS and Linux.
Happy to answer any questions about the architecture or design decisions.

sigil
AI Security Posture Management (AI-SPM) for developer machines: scores AI coding agent guard surfaces (Claude Code, Codex, Gemini CLI, Cursor — hooks, permissions, sandboxes) and ships hash-anchored events to your SIEM. (by Ju571nK)
Project mention: "It's not a bug, it's spec": a zero-click RCE in AI coding agents that three vendors won''t patch | dev.to | 2026-06-02That's the layer I've been poking at. I've been building a small open-source thing (Sigil) that watches agent config files like mcp.json and .claude/settings.json, scores the risk, and emits an event to your SIEM — it doesn't block, it just tells you when the permission state changed while your hands were off the keyboard. Across a fleet of machines that shows up as triage-able alerts — the silent change, made visible:
