3-5: Clarify intent of the two opening paragraphs.Lines 3 and 5 now convey nearly identical information—both describe real-time 3D surgical reconstruction with Gaussian Splatting and temporal deformation. After restructuring to emphasize the end-to-end pipeline, one of these appears redundant.
Verify whether both paragraphs serve a distinct purpose (e.g., detailed vs. summary) or if one should be removed for clarity.
96-107: Dataset setup instructions are clear and complete.The restructured dataset setup (lines 96–107) with numbered steps, inline code blocks, and explicit path placeholders is an improvement. The symlink warning on Line 109 is important context that is appropriately positioned.
41-41: All external links and documentation references in the README are properly formatted and valid. The relative path to the HoloHub glossary (../../README.md#Glossary) is correct, and the glossary section exists in the root README. The file appropriately references and uses HoloHub glossary terms for project-specific locations as required.

Greptile Summary
This PR applies NVIDIA style guide edits to the surgical scene reconstruction README, improving formatting, organization, and readability throughout the documentation.
Major changes:
- Restructured introduction section with clearer feature descriptions
- Enhanced Quick Start section with numbered lists and better command formatting
- Improved dataset documentation with detailed download and setup instructions
- Standardized section headings and terminology throughout
- Reformatted code blocks and citation sections for consistency
Issues found:
- Line 143 contains a critical technical inaccuracy: describes the Temporal Deformation Network as a "Temporal Generative Network (TGN)" for "missing MRI data," which is incorrect for this surgical endoscopy application
- Line 5 introduces redundant content that duplicates line 3
- Inconsistent code block indentation in Step 3 (line 54)
- Terminology errors: "3D Gaussian" should be "3D Gaussians" (line 135), "Gaussian functions" should be "Gaussians" (line 243)
Confidence Score: 3/5
- This PR requires revisions before merging due to technical inaccuracies in the documentation
- Score of 3 reflects that while most style improvements are beneficial, there is a critical technical error at line 143 that misrepresents the Temporal Deformation Network functionality, terminology errors that could confuse readers, and formatting inconsistencies that should be addressed before merging
- Pay close attention to line 143 (incorrect TGN description), line 135 (terminology), and line 243 (terminology)

This description of the Temporal Deformation Network is inaccurate. It mentions "Temporal Generative Network (TGN)" generating "missing MRI data", but this application is for surgical endoscopy (not MRI), and the network performs real-time deformation (not data interpolation/forecasting). This description appears to be copied from an unrelated medical imaging context.
The description should match the actual functionality described in lines 146-150, which correctly describes the HexPlane-based deformation network.

3D Gaussian should be 3D Gaussians (plural) to match the original description and be technically correct, as the model uses multiple Gaussian primitives.

In @applications/surgical_scene_recon/README.md:
- Around line 126-150: The opening sentence of the Temporal Deformation Network
(TGN) description incorrectly references MRI data; update the sentence that
currently reads "Temporal Generative Network (TGN) model generates data that
integrates bidirectional deformation estimation with temporal prediction to
interpolate missing MRI data and forecast future frames" to instead state that
the TGN interpolates missing endoscopic frames and forecasts future frames using
EndoNeRF endoscopic data (RGB images + stereo depth + camera poses), keeping the
rest of the TGN details (HexPlane 4D grid, MLP decoder,
input/output/training/inference) unchanged.

156-157: Minor grammar refinement: "where" clause construction.Lines 156–157 use grammatically awkward constructions:
- "The Coarse Stage where the application learns..."
- "The Fine Stage where a temporal deformation network model is added..."
These read more naturally as "In the Coarse Stage, the application learns..." or "The Coarse Stage: the application learns..."
This is a minor stylistic improvement; the meaning is clear as written.
✏️ Proposed improvements
- 1. The Coarse Stage where the application learns the base static Gaussian models without deformation. - 2. The Fine Stage where a temporal deformation network model is added for dynamic tissue modeling. + 1. **Coarse Stage:** The application learns the base static Gaussian models without deformation. + 2. **Fine Stage:** A temporal deformation network model is added for dynamic tissue modeling.

12-28: Past comment resolved: Use cases typo fixed.Line 23 correctly shows "use cases" (was flagged as "uses cases" in previous review). Feature additions ("Tool Removal," "End-to-End Training") and restructured use cases are clear and well-organized.
131-139: Past comment resolved: "Degree 3" terminology clarified.Line 138 now explains "Degree 3 (16 coefficients per gaussian for view-dependent color)" which directly addresses the previous comment asking "what is 'degree 3'?" The explanation is clear and technical.

My intuition is telling me that the later half of this README has some content that we might not really care to keep, but I can't make those choices without discussion and feedback from a subject matter expert. I did more formatting changes on this article than I had originally intended. These readme's span the gray are between user guide and readme content. I probably leaned more toward user guide formatting style with this. We may not want that. |

Greptile Overview
Greptile Summary
This PR applies style guide edits to the surgical scene reconstruction README, improving formatting, organization, and readability. However, it introduces a critical factual error in the Temporal Deformation Network description.
Key Issues:
- Critical: Line 142 contains incorrect description stating the model "integrates bidirectional deformation estimation with temporal prediction to interpolate missing MRI data and forecast future frames" - this application uses surgical endoscopy video for tissue reconstruction, not MRI data
- Terminology inconsistency: Line 134 changed "3D Gaussians" (plural) to "3D Gaussian" (singular), but the architecture uses multiple Gaussian primitives (the original plural form was correct)
Positive Changes:
- Improved section organization and heading structure
- Better formatting with numbered lists and consistent indentation
- Clearer Quick Start instructions with step-by-step guidance
- Enhanced dataset setup documentation with verification steps
- More detailed training pipeline explanation
Confidence Score: 2/5
- This PR has a critical factual error that misrepresents the application's functionality and must be corrected before merging
- Score reflects one critical factual error (TGN description mentions MRI instead of surgical video) and one terminology inconsistency (Gaussians plural→singular). While the style improvements are beneficial, the factual inaccuracy about the model's purpose is misleading and needs correction
- applications/surgical_scene_recon/README.md requires attention - specifically line 142 (critical factual error) and line 134 (terminology correction)

Greptile Overview
Greptile Summary
This PR applies NVIDIA style guide edits to the surgical scene reconstruction README, improving documentation clarity and structure.
Key Changes:
- Restructured introduction to lead with application purpose
- Expanded Quick Start section with numbered steps and clearer instructions
- Enhanced dataset download and setup instructions with better formatting
- Added detailed training pipeline documentation
- Standardized formatting for citations and code blocks
- Improved section organization (e.g., "Data" → "Pulling Soft Tissues Dataset")
Issue Found:
- Line 54-55: Duplicate command
./holohub run surgical_scene_recon trainwith incorrect indentation in the training code block
Confidence Score: 4/5
- This PR is safe to merge after fixing the duplicate command in the training instructions
- The PR contains style guide improvements to documentation with good restructuring and enhanced clarity. However, there is one syntax error (duplicate command line 54-55) that needs correction. The changes are documentation-only with no code logic changes, making this low-risk overall.
- applications/surgical_scene_recon/README.md requires attention to fix the duplicate command in Step 3
