claude-can-speak

Local AI

Lets Claude Code decide what to say out loud. Most "speak Claude aloud" tools read every reply at you; this one leads with a speak skill that lets Claude voice only what is worth hearing (a "build is done", a heads-up while you look away, a shoutout), while everything else stays text. A speak-everything firehose (its own on/off switch, off by default) is included too, but the deliberate skill is the point. Local neural text-to-speech (Kokoro for natural English, Piper for German, Turkish, and more) runs in Docker, so nothing goes to the cloud. Install with npm install -g claude-can-speak.

portunus-ovpn

Linux Tool

Native KDE Plasma 6 panel widget for switching OpenVPN connections. Import, edit, remove and toggle .ovpn profiles from the panel; one VPN active at a time by default. Drives NetworkManager and KWallet directly, no second VPN daemon and no third-party PPA. Named after Portunus, the Roman god of keys and gates.

vigil

AI Platform

How to build an always-on, autonomous AI operations assistant, and how to keep it diligent. A documentation project: the architecture of a persistent AI operator (per-invocation agent subprocess with a resumable session, supervisor, transport split, channel multiplexers, MCP tools) as a reference design, plus the load-bearing piece most write-ups skip: the doctrine + hooks pattern that re-asserts an engineering standard on every turn so an auto-approved agent keeps verifying before it acts, refuses workarounds, and never claims done without a real run.

hydra-rag-hooks

Local AI

apt install, then type rag <question> in either Claude Code or OpenAI's Codex CLI. UserPromptSubmit hooks for both CLIs from one package. The hook auto-indexes the project on first use, then prepends retrieved chunks from a local LanceDB index before the model sees the prompt. Both CLIs share the same .hydra-index/ store and the same bundled MCP server for model-decided retrieval. Successor to claude-rag-hook.

hydra-llm

Local AI

Run local LLMs the easy way. Pick a model, download it, chat with it. No cloud, no API key, no telemetry.

hydracoder

Local AI

Enter a project goal and local models plan it, build it, and review it, with no hosted AI in the loop. A dark web UI shows each model as a live terminal. Built on hydra-llm and lillycoder, so it runs entirely on your own hardware.
