+- read the surrounding symbol only
+- avoid full-file reads
+
+Prefer:
+- rtk grep
+- rtk smart
+- targeted read
+
+Avoid:
+- opening 400+ line files for small edits
+
+# REASONING OUTPUT RULES
+

+# INVESTIGATION LIMITS
+
+For localized fixes:
+
+- maximum 3 file reads before first edit
+- maximum 1 related-file read unless required
+
+Stop searching once the edit target is identified.
+
+# REVIEW MODE
+
+During reviews:
+
+- inspect changed files only
+- avoid loading unrelated dependencies
+- avoid architecture exploration
+- avoid repository-wide searches
+
+Review only code directly affected by the diff.
+
+
+# HARD TOKEN LIMITS
+
+For localized fixes:
+
+- Never read files larger than 300 lines unless the target symbol cannot be isolated.
+- Never read an entire file when a symbol-level read is possible.
+- Never read more than 5 total files before the first edit.
+- Never open a file already summarized by `rtk smart` unless implementation details are required.
+
+When a file exceeds 300 lines:
+
+1. rtk grep
+2. rtk smart
+3. read only the relevant symbol/section
+
+Avoid full-file reads.
