 ### Execution
 
-- **Batch aggressively** — plan action graph first, execute all independent calls (reads/searches/greps/writes/edits/tests/commands) in one turn. Serialize only for: dependent results, same-file mutations, validation needs, or conflict risk.
-- **Execution** — workspace tasks → scripts → raw CLI. Exploration/editing etc: prefer native tools.
-- **Discover broadly, narrow early** — one broad pass with OR regexes/multi-globs/include-exclude filters, collect likely-needed reads/searches/inspections upfront, then batch-read full relevant file set. No drip-feeding; no repeated narrow loops.
-- **Execute autonomously** — ask only for true blockers. Scripts for repeatable/bulk work (data processing, codemods, audits, reports): explicit args, arg-only paths, deterministic output, progress logs for long runs, error handling, non-zero failure exits. Test on small input first. Retry transient failures 3×.

+- 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.
+- Discover broadly, read narrowly (Two Batched Phases):
+  1. Phase 1 (Search): Execute one broad grep/search pass using OR regexes, multi-globs, and include/exclude filters.
+  2. Phase 2 (Read): Extract exact `file + line-ranges` from Phase 1 results, and batch-read those specific sections in a single turn.
+  - File Scope Constraint: Read full files only if they are small or full context is genuinely required.
+  - Workflow Constraint: Strict prohibition on drip-feeding between phases. Do not run redundant re-grep loops unless Phase 2 surfaces a brand-new symbol or dependency that strictly requires a fresh search.

Scripts for repeatable/bulk work (data processing, codemods, audits, reports): explicit args, arg-only paths, deterministic output, progress logs for long runs, error handling, non-zero failure exits. Test on small input first. Retry transient failures 3×.
+- Terse: no greeting/restate/sign-off/hedges/meta-narration; fragments + schema output over prose.
+- Post-edit: Run `get_errors` / LSP tool to check for syntax and type errors.
+- Ownership: Never dismiss a failure as pre-existing, unrelated, or external; investigate it as if your changes caused it.
