feat(display): configurable tool preview length -- show full paths by default#3841
Conversation
… default Tool call previews (paths, commands, queries) were hardcoded to truncate at 35-40 chars across CLI spinners, completion lines, and gateway progress messages. Users could not see full file paths in tool output. New config option: display.tool_preview_length (default 0 = no limit). Set a positive number to truncate at that length. Changes: - display.py: module-level _tool_preview_max_len with getter/setter; build_tool_preview() and get_cute_tool_message() _trunc/_path respect it - cli.py: reads config at startup, spinner widget respects config - gateway/run.py: reads config per-message, progress callback respects config - run_agent.py: removed redundant 30-char quiet-mode spinner truncation - config.py: added display.tool_preview_length to DEFAULT_CONFIG Reported by kriskaminski

Summary
Tool call previews (paths, commands, queries) were hardcoded to truncate at 35-40 chars across CLI spinners, completion lines, and gateway progress messages. Users couldn't see full file paths like
~/projects/lynis-compliance/ansible/inventory.yml— they'd get~/projects/lynis-compliance/ansible/i...instead.New config option:
display.tool_preview_length(default0= no limit). Set a positive number to truncate at that length.Before (hardcoded 35-40 char truncation)
After (default: full paths)
