AI Tooling

• skills, Matt Pocock’s collection of agent skill files for Claude Code and Codex, covering TDD, code review, and docs-grounded implementation. It installs two ways, as a managed plugin or as an editable copy you own outright, and the editable path is the one that matches how skills actually get used.
• Archify, an agent skill that emits architecture and sequence diagrams as validated JSON and renders them to self-contained HTML. The part worth a click is that each node links back to real source at a specific commit, so the diagram can be checked against the code it claims to describe instead of drifting quietly. The name collides with an unrelated macOS utility that strips universal binaries down to one architecture.
• emdash, a workspace for running several coding agents at once, isolated by git worktrees and containers, with Jira and Linear hooks. It is the worktree-per-agent pattern I run by hand, packaged.
• qm, a multiplayer agent harness that gives everyone at a company an isolated workspace with Slack integration and swappable model backends. Published by an org whose profile reads Y Combinator, new enough that there is barely any history to read, and the two-letter name is going to be impossible to search for.
• Turnstone, a self-hosted agent runtime with shell, file, and search tools, MCP support, RBAC, and an intent-validation gate that judges a tool call before it executes. Self-hosted agent orchestrators are a crowded category now, so the part I find interesting is the license: it moved from BSL 1.1 to Apache-2.0 at v1.6.0. Anything you pin below that tag is still source-available rather than open.
• Cloudflare OS, which despite the name is not an operating system. There is no kernel, no boot loader, and no image. It is an agent workspace built on Workers, Durable Object Facets, and SQLite, which you deploy into your own Cloudflare account and update the way you update any Worker. The name means operating system for your company. The source is Apache-2.0 and substantial, not an announcement stub.
• Buzz, Block’s self-hostable workspace where people and agents share channels, built on Nostr so chat, code review, and CI events land in one signed log. Agents get cryptographic identities on the same footing as people rather than bot-flagged accounts. I am curious whether that framing survives contact with a real team, because every other tool in this space treats the agent as a service account.

Memory and Context

• Basic Memory, an MCP server that keeps an assistant’s memory as plain Markdown files on disk, indexed in SQLite, with wiki-style [[links]] forming the graph. Both sides read and write the same files, so the memory stays inspectable and portable instead of living in a vector blob you cannot open. It is AGPL-3.0, which matters if you were planning to host it for anyone else.
• Witchcraft, Dropbox’s Rust reimplementation of Stanford’s XTR-Warp semantic search, backed by a single SQLite file with no vector database and no API keys. It ships a CLI, a Python module, and a Node native module, and the example app indexes AI coding session transcripts. The latency figures are theirs, not mine, and the repo has been quiet for about two months.

Version Control

• DeltaDB, Zed’s announced replacement for Git’s commit model: a continuous stream of individually addressable deltas, so a reference anchors to a delta rather than a line number and survives edits around it. The pitch is that several people and agents write to one real worktree at once without conflicts. There is no source and no release yet, only a waitlist and a promise of beta, so read it as a design argument rather than something to try.

Models and Inference

• Soup, a CLI that post-trains a model from a single YAML file with no cloud step in the loop. The claim I want to test is layer streaming: fine-tuning an 8B model on a 4GB laptop GPU. There is a Zenodo DOI and a self-check notebook behind it, and the README notes that a bugfix left one benchmark figure stale, so the numbers want re-running before anyone repeats them.
• Unsloth Desktop, a desktop app for running and fine-tuning models locally with a fallback to cloud APIs, plus hooks into Claude Code and Codex. Still beta, and the speed and VRAM figures on the page are the vendor’s own. Unsloth itself turned up here back in April.
• Switchyard, a Rust proxy from NVIDIA’s NeMo org that routes traffic across model providers while preserving the client’s native OpenAI or Anthropic wire format. The client never learns a new protocol to get routing, which is the interesting constraint. Its own documentation says experimental, not for production use.

Systems Engineering

• sysml-v2-modeling-skill, one guidance document teaching an agent to author SysML v2 models without falling back into v1, UML, or PlantUML habits. Five commits, all landed on one day in June, dormant since. The value here is the domain expertise, not the activity.
• mycelium-hypha, a Claude Code plugin aimed at the same problem with more machinery behind it: metamodel lookup, spec citation, and validation against SysML v2. Ten stars, which is about what this niche looks like from outside.

Both of these circle the question kebnf keeps circling, which is how much of systems engineering language work an agent can actually carry.

Security

• Akrites, a Linux Foundation backed coordination body for vulnerability disclosure, built around a problem that did not exist a few years ago: AI-assisted scanning now files duplicate and low-signal reports faster than maintainers can triage them. It offers a private structured channel under TLP 2.0 to dedupe and synchronize disclosure. Membership runs to six figures for companies, with a free associate tier for open source projects, so it is an industry-funded body rather than a community tool.

Writing

• Hammer, a local-first story and novel writing app in Kotlin Multiplatform with sync, shipping on every desktop and mobile store including F-Droid. Running since 2022 and still cutting releases, which is rarer than it should be for this category.

Play

• Spintronics, circuits built out of gears with no electricity anywhere in them, and a puzzle book that walks from a single loop up to transistors. Same lineage as Turing Tumble. Boxed sets run $83 to $183.
• Outdoor Discovery Center, the ODC Network’s nature center in Holland, Michigan: trails open sunrise to sunset with no entry fee, a birds of prey center, and a nature-based preschool.
