#### What the model sees
-For each step, the loop sends the session's derived messages and visible tool schemas. Non-empty `system/message` nodes carry the prompt, with the latest as the effective version; an empty rendering clears all prompt versions from derived history. It supplies `provider` and `model` variable values but no additional fixed prose. The working-directory service contributes the active directory as user context. The request header always records active tools. Comparing their names with the preceding header emits one `developer/message` for additions and removals, independently of model capability; additions reference the new header. Requests also carry `Session.toolHistory()` for the LLM runtime to construct provider declarations.

Requests also carry `Session.toolHistory()` for the LLM runtime to construct provider declarations. Runtime context is a `` user message. Its first snapshot starts with `Current runtime context.`; later snapshots add `This snapshot supersedes earlier runtime-context snapshots, including any retained in a compaction summary.` The loop compares the ordered names and text in recorded `source.sections`, independently of reminder wording. Unchanged contributions emit nothing; compaction removing the retained snapshot causes a new reminder, including after resume. An empty active set emits `Current runtime context: none. Earlier runtime-context snapshots no longer apply.` inside the same wrapper and records empty sections. Proposals do not count until committed. Literal closing reminder tags are escaped in message text while recorded sections retain their original text.

Load referenced resources only as needed.\n\n\n\n# Word documents\n\nUse `python-docx` for DOCX creation and ordinary edits. Follow an explicit user or applicable AGENTS.md requirement for a project environment or another library. Otherwise call `load_workspace_dependencies` and execute the returned Python path with its bundled libraries. Do not install packages or discover a system Python for the default workflow. If the tool is unavailable, use an already configured environment and report a missing dependency only when it prevents the requested operation.\n\nKeep source scripts, intermediate files, and final documents in the task workspace; the runtime and this skill directory are read-only resources. Use the user's requested language and preserve an existing document's design unless a redesign is requested.\n\nName Python scripts for their task, such as `edit_docx.py`; avoid module names such as `inspect.py`, `docx.py`, or `zipfile.py` that shadow imported libraries.\n\n## Create and edit\n\nFor text edits, locate the target by its text or position and inspect only its runs and formatting. A title can be an ordinary paragraph without a Title style or document-property title. Update the relevant runs; assigning paragraph `.text` destroys run formatting. Save a new file unless an in-place edit is requested. For ordinary text edits, do not unzip the document, enumerate ZIP members, dump raw XML, or inspect core properties, headers, or footers unrelated to the target. Investigate these only for a concrete failure, an ambiguous target, an unsupported feature, or an explicit user requirement. Rebuilding a document can lose unsupported features.\n\nUse paragraph styles for headings and body text. Size tables for the section that contains them, and account for merged cells and nested tables. Chinese, Japanese, and Korean text may need an explicit `w:eastAsia` font assignment in addition to `run.font.name`; font names alone do not establish glyph availability or rendered appearance.\n\nFor a new document, use the selected Python executable:\n\n```python\nfrom docx import Document\n\ndocument = Document()\ndocument.add_heading(\"Project report\", level=0)\ndocument.add_paragraph(\"Summary\", style=\"Heading 1\")\ndocument.add_paragraph(\"The requested findings go here.\")\ndocument.save(\"report.docx\")\n```\n\npython-docx does not paginate or render documents. Do not represent ordinary replacement, colored text, or comments as tracked changes. When real revisions or unsupported OOXML features matter, preserve their package parts and verify the requested operation rather than silently discarding them. When writing package parts directly, create a new ZIP and copy each unchanged member once; appending a replacement member duplicates its name and corrupts the package.\n\n## Check and deliver\n\nReopen the saved document with python-docx and verify the requested content, related formatting, and unchanged content that must be preserved. When these checks pass, stop validation and deliver the file. Do not add ZIP integrity checks, package inventories, or metadata inspection as routine final verification.\n\nCreating a file or changing content with incidental basic formatting does not require additional operations. Load `office-render` for requested images or visual inspection. When styling, font color, spacing, sizing, or text alignment is the requested edit, load `office-render` and inspect the changed page even without a separate visual-check request, unless the user explicitly skips rendering. For PDF output load `office-export-pdf`.\n\nCall `present({\"files\":[{\"path\":\"report.docx\"}]})` with the actual final DOCX path. It exposes the current source file without copying or preserving its bytes, so keep that file in place and do not present temporary QA reports unless requested. If `present` is unavailable, provide the final workspace path using the session's supported file delivery method.\n\n"}],"source":{"kind":"skill-invocation","name":"office-docx","form":"instructions"},"role":"user","id":"{{message:5}}"},"surfaceOp":"append"}

Rebuilding a document can lose unsupported features.\n\nUse paragraph styles for headings and body text. Size tables for the section that contains them, and account for merged cells and nested tables. Chinese, Japanese, and Korean text may need an explicit `w:eastAsia` font assignment in addition to `run.font.name`; font names alone do not establish glyph availability or rendered appearance.\n\nFor a new document, use the selected Python executable:\n\n```python\nfrom docx import Document\n\ndocument = Document()\ndocument.add_heading(\"Project report\", level=0)\ndocument.add_paragraph(\"Summary\", style=\"Heading 1\")\ndocument.add_paragraph(\"The requested findings go here.\")\ndocument.save(\"report.docx\")\n```\n\npython-docx does not paginate or render documents. Do not represent ordinary replacement, colored text, or comments as tracked changes. When real revisions or unsupported OOXML features matter, preserve their package parts and verify the requested operation rather than silently discarding them. When writing package parts directly, create a new ZIP and copy each unchanged member once; appending a replacement member duplicates its name and corrupts the package.\n\n## Check and deliver\n\nReopen the saved document with python-docx and verify the requested content, related formatting, and unchanged content that must be preserved. When these checks pass, stop validation and deliver the file. Do not add ZIP integrity checks, package inventories, or metadata inspection as routine final verification.\n\nCreating a file or changing content with incidental basic formatting does not require additional operations. Load `office-render` for requested images or visual inspection. When styling, font color, spacing, sizing, or text alignment is the requested edit, load `office-render` and inspect the changed page even without a separate visual-check request, unless the user explicitly skips rendering. For PDF output load `office-export-pdf`.\n\nCall `present({\"files\":[{\"path\":\"report.docx\"}]})` with the actual final DOCX path. It exposes the current source file without copying or preserving its bytes, so keep that file in place and do not present temporary QA reports unless requested. If `present` is unavailable, provide the final workspace path using the session's supported file delivery method.\n\n"}],"source":{"kind":"skill-invocation","name":"office-docx","form":"instructions"},"role":"user","id":"{{message:5}}"},"surfaceOp":"append"}
