Claude Code — For Tech Leads & Engineering Managers

You've probably heard your devs talk about Claude Code. Maybe some are already using it. This page is for you — the person responsible for making that adoption consistent, secure, and scalable across the team.

---

The core problem

Left to their own devices, each developer builds their own Claude Code setup. Different CLAUDE.md files, different permission configs, no shared hooks, no observability. The productivity gains are real but chaotic, and the security surface grows unchecked.

A team with a shared configuration is 3-5× more effective than the same devs working with individual setups.

30-minute reading path

Whitepapers are currently in private access — public release coming soon.

1. WP05 — Deploying with a Team (coming soon) (25 min)

   • CLAUDE.md hierarchy (global / project / local)
   • Champions program: how to identify and empower early adopters
   • GitHub Actions for automated review + security scanning
   • Adoption phases: pilot → expansion → generalization

2. Guide Ch.3.5 — Team Configuration at Scale (5 min)

   • How to version your team config in the repo
   • Shared vs personal settings

The 3 things to do this week

1. Version your CLAUDE.md in the repo Create a CLAUDE.md at the root of your main repo. It applies to everyone on the team automatically. Start with coding conventions, architecture decisions, and "never do X" rules.

2. Identify one champion One engineer who's already effective with Claude Code. Give them time to document their setup and run a 1h team session.

3. Add one security hook The minimum: a pre-tool hook that blocks writes to .env files and **/secrets/** paths. Takes 10 minutes to set up, covers a real threat vector.

# Example: hooks/block-sensitive-files.sh
if [[ "$TOOL_INPUT_PATH" =~ \.env$|secrets/ ]]; then
  echo "BLOCKED: sensitive file path"
  exit 2
fi

See Guide Ch.7.4 — Security Hooks for the full set.

Security posture overview

This guide maintains the only public threat database for Claude Code: 15 vulnerabilities and 655 malicious skills catalogued. Key risks for teams:

• Prompt injection via untrusted file content or MCP servers
• Overly permissive settings — allowedTools: ["*"] in production
• Unvetted MCP servers — treat them like npm packages (supply chain risk)
• Missing audit trail — who did what, when

Full coverage in WP03 — Security and WP06 — Privacy (whitepapers, coming soon).

Training your team

If you want structured onboarding rather than self-learning:

• Brown Bag Lunch (1h, free) — intro session covering core concepts + team config live
• Team formation (1-2 days) — hands-on, your codebase, your workflows
• Config audit — review your current setup against security and productivity best practices
