What's Wrong?

Claude Code fails to load custom slash commands (from ~/.claude/commands/) when the user has a ripgrep configuration that enables hyperlinks or forces color output.

Environment:

• Claude Code v2.0.76
• macOS (Darwin)
• iTerm2 terminal

Steps to Reproduce:

1. Create a ripgrep config file (e.g., ~/.ripgreprc or custom path)
2. Add either or both of these settings:

--color=always
--hyperlink-format=default

1. Set RIPGREP_CONFIG_PATH to point to this file in your shell config
2. Create a custom command in ~/.claude/commands/save.md
3. Start Claude Code
4. Observe debug log shows: Failed to read/parse markdown file

Debug Log Output:
2025-12-31T05:02:20.575Z [DEBUG] Total plugin commands loaded: 0
2025-12-31T05:02:20.597Z [DEBUG] Failed to read/parse markdown file:
]8;;file://bigmac.lan/Users/paulbrower/.claude/commands/save.md/Users/paulbrower/.claude/commands/save.md

The file path contains OSC 8 hyperlink escape sequences, causing ENOENT errors.

Root Cause:

Claude Code uses ripgrep internally and inherits the user's RIPGREP_CONFIG_PATH environment variable. When ripgrep outputs file paths with escape sequences (hyperlinks or colors), Claude Code's parsing fails.

Suggested Fix:

When invoking ripgrep internally, Claude Code should either:

• Pass --no-config to ignore user configuration
• Explicitly pass --color=never --hyperlink-format= to override user settings
• Strip ANSI/OSC escape sequences from parsed output

Workaround:

Users must change their ripgreprc to use --color=auto instead of --color=always and remove/comment out --hyperlink-format=default.

What Should Happen?

When invoking ripgrep internally, Claude Code should either:

• Pass --no-config to ignore user configuration
• Explicitly pass --color=never --hyperlink-format= to override user settings
• Strip ANSI/OSC escape sequences from parsed output
