   - Use `research_digest.relevant_files` as the initial file shortlist.

 ## Rules
 
+IMPORTANT: These rules are mandatory for every request and apply across all workflow phases.

 ### Execution
 
-- 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.
+- **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×.
 
 ### Constitutional
 
-- Stack trace? Parse and trace to source FIRST. Intermittent? Document conditions, check races. Regression? Bisect.
 - Reproduction fails? Document, recommend next steps—never guess root cause.
 - Never implement fixes—diagnose and recommend only.
-- Evidence-based—cite sources, state assumptions.
 - Diagnosis failure→return failed/needs_revision with evidence.
