Problem Description

The setup-claude-hooks.sh script is referenced throughout the documentation but is missing from the repository,
preventing users from setting up multi-agent file locking functionality.

Steps to Reproduce

 - Clone the repository: git clone https://github.com/rinadelph/Agent-MCP.git
 - Follow the getting started guide: uv venv && uv pip install -e .
 - Try to run: ./setup-claude-hooks.sh
 - Result: ./setup-claude-hooks.sh: No such file or directory

Expected Behavior

The setup-claude-hooks.sh script should exist and configure Claude Code hooks for multi-agent file locking as
documented.

Current Impact

 - Multi-agent file locking is non-functional for new users
 - Documentation is broken - references non-existent script 5+ times
 - Poor first-time user experience - setup instructions fail
 - Core functionality unavailable - agents can't coordinate file access

Root Cause Analysis

This appears to be a regression from PR #33:

 - Issue #32 documented the same problem (missing setup script)
 - PR #33 allegedly fixed it by adding setup-claude-hooks.sh
 - PR was merged on July 14, 2025 and marked as resolved
 - Script is now missing from main branch (regression occurred)

Evidence of Regression

Documentation still references the script:

 - docs/getting-started.md: ./setup-claude-hooks.sh
 - CONTRIBUTING.md: ./setup-claude-hooks.sh
 - Multiple troubleshooting sections mention it

PR #33 Details:

 - Claimed to add ✨ setup-claude-hooks.sh - New automated setup script
 - Issue #32 was marked "RESOLVED" with comment about merged PR #33
 - But the file is missing from current main branch

Environment

 - Date Discovered: December 8, 2024
 - Branch: main (latest)
 - OS: Windows (affects all platforms)
 - Python: 3.14.0
 - Installation method: uv venv && uv pip install -e .

Suggested Fix

Either:

 - Restore the missing script from PR #33 history
 - Recreate the script based on the template in agent_mcp/templates/agent_startup.sh
 - Update documentation to remove references if script is intentionally removed

Workaround

Currently there is no workaround - multi-agent file locking functionality is completely unavailable to new users.

Additional Context

The agent_mcp/templates/agent_startup.sh file exists and shows the expected structure for tmux-based agent sessions,
suggesting the setup script should configure Claude Code hooks to integrate with this system.

This regression affects every new user trying to use Agent-MCP's core multi-agent collaboration features.
