No manual editing w
Zencastr
Zencastr is an all-in-one remote recording platform for podcasters, video creators, and interviewers. Founded in 2016, endorsed by people like Seth Godin and Sam Harris. The pitch: spend less time juggling tools, more time making content.
AgentBox
AgentBox is Rui Carmo's Docker-based sandbox for running coding agents in isolation. The README is refreshingly honest about the state of the art: "There's no perfect way to sandbox agents (yet), but containers are a practical start." MIT licensed, ~141 stars, mostly Dockerfile and Makefile.
Kurt Vonnegut - Enough
True story, Word of Honor: Joseph Heller, an important and funny writer now dead, and I were at a party given by a billionaire on Shelter Island.

Claude Sonnet 5
Claude Sonnet 5 is Anthropic's mid-tier Claude model, released early July 2026. Anthropic calls it "our most agentic Sonnet yet": it plans, drives browsers and terminals, and runs autonomously at a level that required Opus-class models a few months earlier. The pitch is simple: near Claude Opus 4.8
Claude Tag
Claude Tag is Anthropic's way for teams to work with Claude as a teammate inside Slack. Announced June 23, 2026 (beta for Claude Team and Enterprise), it lets Claude join Slack as a team member: admins grant it access to selected channels, tools, data, and codebases, and anyone in a channel can tag

AI and Context Engineering Glossary
Unified terminology reference for AI, Context Engineering, and Knowledge Management. Organized by domain. Each entry links to its dedicated vault note.
Comprehension Debt
Comprehension debt is the gap between what a system does and what its owners actually understand about it. Every line of code you ship without understanding adds to it. You still own the behavior; you just can't explain it, debug it, or safely change it.
Loop Engineering Went Mainstream
Mid-2026, and "loop engineering" is now the phrase you keep seeing in AI conversations. Boris Cherny from Anthropic (creator of Claude Code) said it directly: "I don't prompt Claude anymore. My job is to create loops." Peter Steinberger made the same point in his own words: stop prompting coding age
Markr
Markr is a tiny desktop timer that lets you bookmark moments while you record, so editing means jumping to marks instead of scrubbing the whole clip. Mark the moment as it happens, not after. Electron/React/TypeScript, MIT.
Obsidian AI Skills by Steph Ango
Obsidian AI Skills (the `obsidian-skills` repository) is an open set of Agent Skills published by Steph Ango (kepano), Obsidian's CEO, that teach AI agents to read and write Obsidian's file formats natively instead of guessing at them. It went up in June 2026 and blew up fast; it was already past 37

Agentic Resource Discovery Specification (ARD)
Agentic Resource Discovery (ARD) is an open, draft specification (Apache 2.0 License) for publishing, discovering, and verifying AI capabilities across the web.

Code Mode MCP Pattern
Code Mode is a pattern for using MCP) tools where, instead of exposing each tool directly to the model as a callable function, you give the model a typed API (TypeScript or Python) and ask it to write code that calls those tools. The code runs in a sandbox, and only the final result comes back to th
TypedMark
TypedMark is an open specification for typed Markdown note systems.

Docker Sandboxes
Docker Sandboxes runs each AI agent session inside a dedicated microVM with its own private Docker daemon, isolated by the VM boundary, with no path back to the host. It exists to solve one problem: running autonomous coding agents safely. As Docker puts it, an LLM deciding its own security boundari
Sandcastle (AI)
Sandcastle is a TypeScript library by Matt Pocock for orchestrating AI coding agents in isolated sandboxes. You invoke an agent with a single `sandcastle.run()` call; the library runs it in a sandbox on a configurable branch, then merges the resulting commits back into your repo. It targets parallel

The Docker MCP Toolkit is the Docker Desktop feature that removes the operational friction of running Model Context Protocol (MCP)) servers locally. You configure an MCP server once and share it across multiple AI clients via named profiles (collections of servers), instead of repeating per-client c
Docker Compose for AI
Docker Compose now treats AI models as first-class application components via a top-level `models:` element, so you can wire models, agents, and tools into one declarative file and bring them up with a single `docker compose up`. The required field is `model:` (the OCI artifact pulled and run by Doc
