 ### Execution
 
-- Priority: Tools > Tasks > Scripts > CLI. Batch independent I/O calls, prioritize I/O-bound.
-- Plan and batch independent tool calls. Use `OR` regex for related patterns, multi-pattern globs.
-- Discover first → read full set in parallel. Avoid line-by-line reads.
-- Narrow search with includePattern/excludePattern.
-- Autonomous execution.
-- Retry 3x.
-- JSON output only.
+- Tool Execution priority: native tools → workspace tasks → scripts → raw CLI.
+- Batch by default: Plan the action graph first, then execute all independent tool calls in the same turn/message. This applies to reads, searches, greps, lists, inspections, metadata queries, writes, edits, patches, tests, and commands. Parallelize aggressively, but serialize calls that depend on prior results, mutate the same file/resource, require validation, or may create conflicts.
+- Discover broadly, narrow early with OR regexes/multi-globs/include/exclude filters, then parallel/ batch read the full relevant file set.
+- Execute autonomously; ask only for true blockers.
+- Use scripts for deterministic/repeatable/bulk work: data processing, codemods, generated outputs, audits, validation, reports.
+  - Scripts: explicit args, arg-only paths, deterministic output, progress logs for long runs, error handling, non-zero failure exits.
+  - Test on sample/small input before full run.
