Makimono: Marketplace and API for CLAUDE.md Playbooks
Makimono is a newly launched marketplace and open API for sharing finished instruction files (CLAUDE.md playbooks, skills, dev playbooks) that let coding agents skip trial-and-error. The platform exposes a no-auth, CORS-enabled API (with a /llms.txt entry) designed for agents to search and retrieve playbooks autonomously. Listings include an 'roi' metric estimating tokens saved, and contributors can publish via a prompt-driven flow that collects files, strips secrets with per-item approval, drafts metadata, and submits for review. A Claude Code plugin (hosted on GitHub) integrates find-before-build and publish workflows. The project launched from Japan with a small initial catalog and is seeking more contributions and feedback.
Small-scale product launch that introduces an agent-focused marketplace and open API; potentially useful for developer productivity but currently limited in scale and listings.

Open-sourced Claude Code Setup and Five Skills
The author (AI by Aakash) published and open-sourced a '0 to 100' starter kit for Anthropic's Claude Code and Claude Cowork, providing two GitHub repositories: pm-claude-skills (five ready-made Claude Skills plus a SKILL-TEMPLATE.md) and pm-claude-code-setup (a CLAUDE.md persistent-context template and a .claude/skills PRD Writer example). The post documents how to import memory from other AI services into Claude using a copy-paste prompt and explains installation steps (git clone and copying skill files). The write-up highlights how skills enforce workflow consistency, describes PRD Writer behavior, and gives practical usage guidance for Cowork and Code. The newsletter also summarizes recent AI industry news (e.g., Google’s Nano Banana 2, Anthropic turning down a Pentagon contract) but its primary announcement is the open-source Claude tooling and setup resources for knowledge-worker automation.
Permission-first CLAUDE.md Agent Stack for Claude Code
A developer published Full Stack HQ, an open-source, MIT-licensed configuration kit that imposes a permission-first workflow for Claude Code agents. The kit centralizes global rules (CLAUDE.md and GEMINI.md), specialist agents, skills and workflows so AI coding agents plan actions, present phased plans, and wait for explicit human approval before executing. Full Stack HQ bundles 10 specialist agents, 28 skill modules, and 10 slash-command workflows; it enforces separation of planning and execution, role-based routing to domain specialists, explicit code-style rules, and an automated security checklist. Install scripts for Mac/Linux and Windows automatically detect IDEs and configure the kit. The project is available on GitHub at github.com/sabahattink/antigravity-fullstack-hq.
CLAUDE.md: Guide to Configuring Claude Code
This DEV.to tutorial (published 2026-06-21) explains CLAUDE.md, a small markdown file that Claude Code reads at the start of every session to provide project-specific context. The article describes what to include (stack with versions, directory map, build/test commands, conventions, generated files), where to put it (project root), and how to bootstrap it using Claude Code's /init command. The author argues a concise, accurate CLAUDE.md compounds value across sessions and links to a free quick-start cheat sheet plus a paid, deeper Gumroad guide covering hooks, subagents, commands, skills and plugins.
