Before write or edit, call sideroom_guidelines with the target path. Reuse loaded guides in this run; reload after compaction. Alternatively, use the read tool without offset or limit to load in full:
- ${GUIDELINE_SKILL_PATH}
- for the extension of the file you will change, one of: ${LANGUAGE_GUIDE_INDEX}
Only successful loads without truncation count. Until all required documents are loaded, do not call write or edit and do not mutate files through bash or another tool; the extension blocks those mutations.`;
