System and Generic Utilities

Part of src/cmds/ — see also docs/contributing/TECHNICAL.md

Specifics

• read.rs uses core/filter for language-aware code stripping (FilterLevel: none/minimal/aggressive)
• grep_cmd.rs reads core/config for limits.grep_max_results and limits.grep_max_per_file
• local_llm.rs (rtk smart) uses core/filter for heuristic file summarization
• format_cmd.rs is a cross-ecosystem dispatcher: auto-detects and routes to prettier_cmd or ruff_cmd (black is handled inline, not as a separate module)

Cross-command

• format_cmd routes to cmds/js/prettier_cmd and cmds/python/ruff_cmd
