Slash Command Budget Management

What changed: Slash command descriptions are now limited to prevent excessive context window usage

How it works now:

• Default character budget: 15,000 characters
• Configurable via SLASH_COMMAND_TOOL_CHAR_BUDGET environment variable
• Shows notification when commands are truncated: "(Showing 25 of 50 commands due to token limits)"
• Only includes commands with user-specified descriptions (excludes built-in commands without descriptions)

Details:

• Prevents unlimited context consumption with many custom commands
• Prioritizes commands by order (shows first N that fit in budget)
• Separate token tracking for slash command overhead
