Enterprise Claude Plugin Marketplaces Need Governance
The article argues that organizations building private Claude Code plugin marketplaces must treat them as governance platforms, not just distribution channels. Claude Code plugins are directories with manifests (.claude-plugin/plugin.json) and executable skills, agents, hooks and MCP servers that run fully trusted code in developer sessions (no sandboxing as of 2026). The author outlines a three-layer model (skill/plugin, marketplace manifest, managed settings) and emphasizes pinning plugins to commit SHAs in marketplace.json for deterministic releases. Critical enterprise controls include strictKnownMarketplaces to lockdown allowed marketplaces and PreToolUse hooks to enforce runtime policies (allow/block/modify tool calls). The piece lists common mistakes (using a private repo as a marketplace, overtrusting public directories, missing seed directories for air‑gapped environments, and relying on scanning alone) and gives a practical first‑week setup checklist for secure internal marketplaces.
Provides actionable enterprise governance and security guidance for LLM plugin marketplaces (version pinning, managed settings, runtime hooks). Relevant to organizations integrating LLMs into developer workflows but not industry‑shifting.

Key Takeaways & Evidence Grounding
- Claude Code plugins are directories containing a .claude-plugin/plugin.json manifest and may include skills, agents, hooks, and MCP servers.
- Plugins run fully trusted code inside developer sessions and there is no sandboxing in 2026.
- marketplace.json should pin plugins to commit SHA values (not tags) to ensure deterministic versions across the org.
- Managed setting strictKnownMarketplaces controls which marketplaces employees may add and can enforce lockdown or allowlists.
- PreToolUse hooks execute before tool calls and can allow, block, or rewrite calls to enforce runtime policy and auditing.

Build a Team OS Using Claude Code
This article outlines a practical guide for product managers to build a Team Operating System (Team OS) using Claude Code and a shared repository. It describes a repository architecture (root Claude MD, folder-level CLAUDE.md files, and a .claude/ folder for agents, commands, and skills), an ownership model, and a three-tier context-loading strategy (always-loaded root, folder-level indexes on query, and content loaded on demand) to conserve LLM context window and reduce hallucinations. The piece covers planning workflows (plan mode, lightweight alignment), agent orchestration (temp files, verification prompts), analytics integration (queries, schemas, Snowflake), and operational practices to keep the repo current. Examples, templates, a checklist for feature launches, and recommended daily prompts and automation flywheels are provided.
Ten CLAUDE.md Rules for Safe Claude Code
Rene Zander published a developer post (Apr 23, 2026) that collects and extends CLAUDE.md guidance for using Claude to write and run code. He preserves Forrestchang’s four edit-time rules (Think Before Coding; Simplicity First; Surgical Changes; Goal-Driven Execution) and adds six runtime rules derived from his fixclaw project: prefer deterministic code for operational tasks, declare token budgets and halt on breaches, treat human-in-the-loop approval steps as first-class, validate AI outputs against schemas, sanitize operator input to prevent prompt injection, and log rejections silently. The article links to a GitHub gist and describes fixclaw (a Go pipeline engine) as an implementation where Claude drafts and classifies but never executes side-effecting actions. Sentry monitoring is mentioned as a practical observability option.
Claude Code Guide for Non-Technical Product Managers
This newsletter episode features Andre Albuquerque demonstrating a four-level, step-by-step path for non-technical product managers to build with Claude Code and related tools. Albuquerque — who has worked with thousands of product people — live-builds a functional product and explains how to start with low-friction tools (Lovable) then progress to Claude Code + GitHub, add Vercel and Cursor for faster branching and previews, and finally deploy multi-agent stacks (Team Claude Config). The piece covers practical practices: connecting Lovable to GitHub, using CLAUDE.md to encode team rules, agent roles (Researcher, Discovery, Designer, Engineer, Implementer), and skills (JTBD, OST, MoSCoW) to reduce “latency tax,” improve technical empathy, and iterate infrastructure. The post includes links to a GitHub repo (AndreAlbuquerque/claude-config), podcast/video resources, and sponsor/tool mentions like Customer.io, Amplitude, Bolt and Ariso.
