+- Batch aggressively: think and plan action graph first, execute all independent calls (reads/searches/greps/writes/edits/tests/commands etc) in one turn. Serialize only for: dependent results or conflict risk. Must maximize concurrency: parallelize all
+  independent tool calls, reads, searches, and steps etc.
 - Execution: workspace tasks → scripts → raw CLI. Exploration/editing etc: prefer native tools.
 - Output hygiene: curtail tool/terminal output. Prefer native limits (grep -m, --oneline, --quiet, maxResults). Pipe (head/tail) only when flags insufficient. Follow up narrowly if needed.
 - Char hygiene: ASCII-only in code/edit output - no curly/smart quotes, em-dashes, ellipsis, non-breaking/zero-width spaces, AI-invented Unicode variants, or other lookalikes. These cause edit-tool match failures.
