Affaan Mustafa's Everything Claude Code

Affaan Mustafa is a multi-time founder and former AI/ML researcher now working as Product Lead at PMX Trade in San Francisco. He won the Anthropic x Forum Ventures hackathon in September 2025 building zenith.chat using Claude Code, then released his entire configuration as Everything Claude Code for others to learn from.

Background

Mustafa has been using Claude Code since its experimental rollout in early 2025. His academic work focused on applied math and computational research at the University of Washington, with publications on market manipulation analysis and trading frameworks.

His production experience includes:

• Core contributor to elizaOS (17,400+ GitHub stars)
• Built autonomous Solana trading agents processing millions in volume
• Co-founded 0em Labs building the “inbox0” MCP marketplace

When his configurations thread hit 900,000 views on X, JP Caparas wrote an explainer that broke down the methodology for developers who wanted to adopt it.

The Repository Structure

Everything Claude Code bundles production configs across six categories:

Install by copying to your ~/.claude/ directories and merging hooks into ~/.claude/settings.json.

Subagent Architecture

Mustafa uses nine specialized agents that Claude can delegate tasks to:

The delegation model keeps each agent focused. Instead of one overloaded context, specialized agents handle their domain with targeted knowledge.

Context Window Management

Mustafa’s most cited advice: Don’t enable all MCPs at once.

From his guide:

“Your 200k context window can shrink to 70k with too many tools enabled.”

His recommended limits:

Use disabledMcpServers in project config to disable unused MCPs. This preserves context for the code and conversation that matter.

Hook Examples

Hooks trigger automated behaviors on tool use. One example from his config warns about debug statements:

{
  "PreToolUse": [{
    "matcher": "Write|Edit",
    "hooks": [{
      "type": "command",
      "command": "check_for_console_log"
    }]
  }]
}

This fires before any write operation, catching console.log statements before they reach production code.

Slash Commands

Quick-access commands for common workflows:

Commands invoke the appropriate agent with pre-configured context.

Rules and Constraints

The rules/ directory contains modular constraint files:

• Security rules: Input validation, auth requirements
• Coding style: Language-specific conventions
• Testing rules: 80% coverage minimum
• Git workflow: Commit message format, branch naming
• Agent delegation: When to hand off to specialists

Rules load automatically, so Claude follows them without prompting.
