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)
• search.rs backs both rtk grep and rtk rg: it runs the invoked engine (never substituting one for the other) and groups its output, reading core/config for limits.grep_max_results and limits.grep_max_per_file. Format-altering flags (-c, -l, -L, -o, -Z) bypass RTK filtering and run raw.
• ctest_cmd.rs takes the run total from the first result line (covering --stop-on-failure, disabled tests, and forwarded suites) and validates both result lines and the summary against it, deduplicates retries by test number+name, folds wrapped result lines until their terminator, falls back to the raw FAILED: trailer for unparsed failures, keeps the error trailer behind an empty run, labels and caps failure details with tee recovery, and attributes diagnostics safely under -j; explicit verbose/show-only/help/version flags and dashboard modes bypass filtering, except -T Test, which prints ordinary test output and stays filtered.
• 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
