Best CLAUDE.md Templates for Teams (2026)
A good CLAUDE.md file makes Claude Code consistently useful for every developer on your team. Here are the best templates ranked by team adoption, consistency, and maintainability.
Why Teams Need CLAUDE.md Templates
Without a shared CLAUDE.md, every developer gets a different Claude experience. One developer might get careful, question-asking Claude. Another gets assume-everything-and-go Claude. A shared template ensures consistent behavior, coding standards, and security practices across the team.
1. Karpathy Skills + Project Rules (Best Overall)
Source: github.com/forrestchang/andrej-karpathy-skills
What it provides: Four behavioral principles (Don’t Assume, Don’t Hide Confusion, Surface Tradeoffs, Goal-Driven Execution) as the foundation, with space for project-specific rules below.
Why it works for teams: Zero training required. Commit to repo, every developer benefits. The four principles are simple enough to explain in a standup meeting.
Template structure:
# Behavioral Principles
[Karpathy's 4 principles]
# Project Standards
- Language: TypeScript strict mode
- Framework: Next.js 14
- Tests: Vitest, minimum 80% coverage
- Style: Prettier defaults, no semicolons
- Package manager: pnpm only
Install:
curl -o CLAUDE.md https://raw.githubusercontent.com/forrestchang/andrej-karpathy-skills/main/CLAUDE.md
Limitation: No structured commands or agents — purely behavioral. Combine with SuperClaude or custom commands for structure.
2. SuperClaude Team Configuration
Source: github.com/SuperClaude-Org/SuperClaude_Framework
What it provides: 30 standardized slash commands, 16 agents, and 7 behavioral modes that every team member gets access to.
Why it works for teams: Everyone speaks the same command language. /review means the same thing for every developer. Mode switching lets developers adjust to task type.
Install:
pipx install superclaude && superclaude install
Limitation: Requires every team member to install the CLI. Keep versions synchronized across the team.
3. Claude Code Templates — Enterprise Agent Pack
Source: github.com/davila7/claude-code-templates
What it provides: Pre-built agent templates for common team roles: code reviewer, architect, tester, security auditor, documentation writer.
Why it works for teams: Pick the agents that match your team’s roles and commit them to the repo. New team members get the right agents automatically.
Install:
npx claude-code-templates@latest
# Select: Agents → Enterprise pack
Limitation: Agents are independent — no mode switching or framework-level integration. Each template is a standalone file.
4. Security-First CLAUDE.md (From Ultimate Guide)
Source: github.com/FlorianBruniaux/claude-code-ultimate-guide
What it provides: A CLAUDE.md template with security constraints: no hardcoded secrets, mandatory input validation, dependency scanning, and security review before deployment.
Why it works for teams: Companies with compliance requirements need Claude to follow security practices consistently. This template encodes those requirements as behavioral rules.
Template structure:
# Security Rules
- NEVER write API keys, passwords, or tokens in source files
- ALWAYS validate external input before processing
- Flag any dependency with known CVEs
- Require authentication check on every API endpoint
- Log security-relevant actions (login, permission changes, data access)
# Code Review Requirements
- Every PR must pass security scan before merge
- No eval(), new Function(), or dynamic code execution
- No SQL string concatenation — use parameterized queries
Limitation: Security-focused only. You still need behavioral principles and coding standards from other templates.
5. Academic Workflow Template
Source: github.com/pedrohcgs/claude-code-my-workflow
What it provides: 28 skills and 14 agents configured for academic work: LaTeX, R, citations, statistical analysis, and paper writing.
Why it works for teams: Research groups and academic teams get consistent LaTeX formatting, citation handling, and statistical methodology.
Install:
git clone https://github.com/pedrohcgs/claude-code-my-workflow.git
cp claude-code-my-workflow/CLAUDE.md your-research-project/CLAUDE.md
Limitation: Narrow focus. Not useful for non-academic teams.
6. Claude Howto Starter Template
Source: github.com/luongnv89/claude-howto
What it provides: Copy-paste CLAUDE.md templates for common project types: React, Python, Go, Rust, and more. Each template includes language-specific conventions and tool preferences.
For more on this topic, see CLAUDE.md Templates Library.
Why it works for teams: Language-specific templates mean the CLAUDE.md matches your stack exactly. Less customization needed.
Limitation: Starting templates that need customization. Not production-ready without adding team-specific rules.
7. Composite Template (Community Best Practice)
What it provides: A layered CLAUDE.md that combines multiple sources.
Recommended structure:
# Layer 1: Behavioral Foundation (Karpathy)
[4 principles]
# Layer 2: Security (Ultimate Guide)
[Security constraints]
# Layer 3: Tech Stack (Claude Howto template)
[Language/framework specific rules]
# Layer 4: Team Standards (Your own)
[Coding conventions, PR requirements, naming]
# Layer 5: Project Context (Your own)
[Architecture decisions, domain knowledge, file structure]
This layered approach gives you the best of every template while maintaining clear structure.
Limitation: Larger file means more context tokens. Keep total length under 500 lines.

CLAUDE.md Maintenance for Teams
A CLAUDE.md that is never updated becomes stale and less effective. Establish a maintenance process:
Monthly review: One team member reviews the CLAUDE.md for outdated rules. Architecture decisions change, coding standards evolve, and new tools get adopted. The CLAUDE.md should reflect current reality.
PR-based updates: Treat CLAUDE.md changes like code changes — submit PRs, get reviews, and discuss significant rule changes. This prevents one developer from silently changing Claude’s behavior for the whole team.
Onboarding integration: When new developers join, have them read the CLAUDE.md as part of onboarding. They learn both the project standards and Claude’s behavioral configuration simultaneously.
Deprecation process: When removing a rule, comment it out first with a date note. After two sprints with no issues, delete it permanently. This prevents accidentally removing rules that prevent recurring problems.
Anti-Patterns to Avoid
Common CLAUDE.md mistakes that reduce effectiveness:
Too long: A 1,000-line CLAUDE.md wastes context tokens and dilutes important rules. Keep it under 300 lines. Every line should earn its place.
Too vague: “Write good code” is useless. “Functions under 60 lines, 2 assertions per function, Google-style docstrings” is actionable.
Contradictory rules: “Move fast and break things” combined with “Never deploy untested code” confuses Claude. Resolve contradictions before committing.
Copy-pasted without customization: Using a template verbatim without adding your project context means Claude knows the general rules but not your specific architecture, database schema, or business logic.
Duplicating system prompt instructions: If the system prompt already tells Claude to prefer Edit over Write, repeating that in your CLAUDE.md wastes tokens. Read the system prompts repo to know what is already covered.
Getting Started for Your Team
- Start with Karpathy Skills as the base (#1)
- Add security rules if you have compliance requirements (#4)
- Add language-specific templates from Howto (#6)
- Add your team’s coding standards and domain knowledge
- Commit to your repo and document in your team wiki
- Set a monthly review cadence
