Building a Team OS with Claude Code
Aakash Gupta and Hannah Stulberg published a paid Substack guide (May 8, 2026) describing how to build a shared "Team OS" using Claude Code. The authors recap examples from DoorDash, Pendo, Google and an independent builder who converged on a common three-layer architecture: a shared context repo (searchable Markdown), agent-accessible knowledge, and natural-language querying for teammates. The piece argues Team OSes make institutional knowledge discoverable to both humans and AI agents, reducing context bottlenecks. The full article includes a technical deep dive, a four-week build plan, usage patterns, adoption playbook and downloadable starter resources for paid subscribers.
Practical guide demonstrating convergent architectures for LLM-powered team knowledge systems; useful to product and engineering teams adopting agentic workflows but not industry-shifting.

Key Takeaways & Evidence Grounding
- Aakash Gupta and Hannah Stulberg co-authored a Substack post titled "I spent the last week building you a Team OS in Claude Code" published 2026-05-08.
- The article documents four implementations of a "Team OS": Hannah Stulberg (DoorDash), Dave Killeen (Pendo), Gabor Meyer (Google), and Carl Vellotti (independent builder).
- The proposed Team OS uses a shared, searchable repo of team context (Markdown files) that AI agents (e.g., Claude Code) can query in natural language.
- The public post references OpenAI's Harness Engineering piece and notes the Team OS architecture is portable across coding-agent platforms (Codex, Cursor, GitHub Copilot) though examples use Claude Code.

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.
Build an AI-Native Team with a Company OS
This guide explains how product leaders can build an AI-native company by implementing a Company OS: a single GitHub repo mapping every team’s activities to opinionated 'skill' files that are uploaded into Claude’s organization settings so workers encounter the right workflow inside their existing tools. Jiaona Zhang (CPO at Laurel) describes how Laurel uses this structure to let non-engineering roles (even CSMs) ship to production, the creation of a full-time AI Ops role to scale workflows, and a captain model for end-to-end feature ownership with two review tracks (fast vs. full). Practical adoption tactics include company hackathons to break technical assumptions, daily Slack briefings with embedded skills, and a four-level framework for measuring AI maturity across teams.
Claude Code: From Terminal Tool to Agentic AI OS
This technical guide explains why Claude Code represents a new class of developer tool and how Anthropic is productizing it into a managed, enterprise-grade agentic OS. Unlike prior code assistants that worked file-by-file, Claude Code reads whole projects (filesystem + git history) and runs an autonomous TAOR (Think–Act–Observe–Repeat) loop that lets the model orchestrate multi-step tasks. The author contrasts Claude Code with the open-source OpenClaw architecture (large GitHub traction but security exposure) and notes Anthropic’s strategy: expand Claude Code’s scope (remote control, browser automation, Office integrations, desktop Cowork, hooks/skills with verified publishers, Agent SDK) while holding the trust boundary to solve security and compliance. The piece cites adoption signals (roughly 4% of public GitHub commits attributed to Claude Code, projected 20%+ by end of 2026) and highlights operational and supply-chain risks tied to agentic systems.
