  • Explore repository structure and understand codebase organization
  • Create automated analysis script to categorize code types
  • Generate comprehensive CODE_ANALYSIS.md documentation
  • Categorize code into 19 distinct categories with subcategories
  • Commit the analysis script to scripts/ directory
  • Add npm script command "analyze-code" to package.json
  • Format script according to project code style (single quotes, no semicolons)
  • Keep CODE_ANALYSIS.md updated with latest codebase statistics
  • Add separate "Storybook" category for .stories.ts/tsx files (179 files, 38,040 lines)
  • Update categorization logic to detect Storybook files early
  • Re-run analysis with new categorization
  • Update CODE_ANALYSIS.md with Storybook statistics
  • Create GitHub Actions workflow to auto-update analysis monthly
  • Fix Prettier formatting issues (trailing spaces)

Prettier Compliance

Fixed formatting issues in:

  • .github/workflows/monthly-code-analysis.yml - Removed trailing spaces in YAML multiline strings
  • docs/CODE_ANALYSIS.md - Removed trailing spaces from markdown header

All files now pass pnpm run format:check

Greptile Summary

Adds a developer tooling script (scripts/analyze-code-lines.ts) that walks the repository, categorizes files into 18 code types, and prints a summary to the console. Also adds a static docs/CODE_ANALYSIS.md report and an npm script entry.

  • Misleading report generation claim: The script's doc comment and console output claim it writes to docs/CODE_ANALYSIS.md, but it only outputs to the console. The markdown report is a separate, manually-written static file that will become stale. The regeneration instructions in the documentation are incorrect.
  • Incomplete App Router categorization: The script only recognizes page.tsx and layout.tsx as App Router files, missing 33+ loading.tsx files and not-found.tsx which fall into the "other" category, skewing results.
  • Static documentation risk: Committing a 324-line snapshot report with no automated way to keep it current adds maintenance burden. Consider either implementing actual file output in the script, or not committing the static report.

Confidence Score: 3/5

  • Low-risk tooling PR with no production code impact, but contains misleading documentation that could confuse developers.
  • The script is a read-only analysis tool with no production impact, but the disconnect between documented behavior (writes markdown report) and actual behavior (console-only output) is a functional issue. The static markdown report will immediately become stale with no automated regeneration path.
  • Pay close attention to scripts/analyze-code-lines.ts (misleading file output claims) and docs/CODE_ANALYSIS.md (static report with incorrect regeneration instructions).

Important Files Changed

Filename Overview
scripts/analyze-code-lines.ts New analysis script categorizes files into 18 types, but claims to write a markdown report it never generates, and misses some App Router file conventions (loading.tsx, not-found.tsx).
docs/CODE_ANALYSIS.md Static, manually-written report with misleading regeneration instructions. Will become stale immediately as no automation keeps it in sync with the actual codebase.
package.json Adds analyze-code npm script pointing to the new analysis tool. Straightforward, no issues.

PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

⏱️ Estimated effort to review: 3 🔵🔵🔵⚪⚪
🧪 No relevant tests
🔒 No security concerns identified
⚡ Recommended focus areas for review

Performance

Repository traversal and line counting are fully synchronous and read whole file contents into memory, which can be slow on large repos and may impact developer experience/CI if run there. Consider using async FS APIs, streaming line counting, and/or adding basic progress/timeout/limits.

function countLines(filePath: string): number {
  try {
    const content = fs.readFileSync(filePath, 'utf-8');
    return content.split('\n').length;
  } catch {
    return 0;
  }
}

/**
 * Walk through a directory recursively
 */
function walkDirectory(dir: string, stats: Map<string, FileStats[]>) {
  const entries = fs.readdirSync(dir, { withFileTypes: true });

  for (const entry of entries) {
    const fullPath = path.join(dir, entry.name);

    if (entry.isDirectory()) {
      if (!EXCLUDE_DIRS.has(entry.name)) {
        walkDirectory(fullPath, stats);
      }
    } else if (entry.isFile()) {
      if (EXCLUDE_FILES.has(entry.name)) {
        continue;
      }

      // Only count code files
      const ext = path.extname(entry.name);
      if (
        ['.ts', '.tsx', '.js', '.jsx', '.json', '.md', '.mdx', '.css', '.scss'].includes(ext)
      ) {
        const lines = countLines(fullPath);
        const { category, subcategory } = categorizeFile(fullPath);
        const relativePath = path.relative(process.cwd(), fullPath);

        if (!stats.has(category)) {
          stats.set(category, []);
        }

        stats.get(category)!.push({
          path: relativePath,
          lines,
          category,
          subcategory,
        });
      }
    }
  }
}
Misclassification

The categorization is based on path substring matches and may incorrectly classify files due to broad rules and ordering (e.g., any path containing scripts/ becomes scripts, any /components/ file defaults to UI utilities if not .tsx, /server/ handling depends on containing /server/). Validate category precedence, ensure patterns are robust across OS path separators, and consider allowing configuration/overrides.

function categorizeFile(filePath: string): { category: string; subcategory?: string } {
  const normalizedPath = filePath.toLowerCase();
  const fileName = path.basename(filePath);

Determinism

“Top 5 largest files by category” iterates over the unsorted Map insertion order and sorts the same array in-place, which can make output ordering and subsequent use of the stats array less predictable. Consider iterating categories in a consistent order (e.g., sorted) and avoid mutating the stored arrays when selecting top files.

for (const [category, files] of stats.entries()) {

Automate report generation and exclude it from version control

The analysis script should be updated to automatically generate the
docs/CODE_ANALYSIS.md report. This file should then be added to .gitignore or
updated via a CI job to prevent stale, generated content from being committed to
the repository.

Examples:

docs/CODE_ANALYSIS.md [1-324]
# Code Line Analysis Report

**Generated:** February 10, 2026  
**Total Lines of Code:** 224,555 lines  
**Total Files Analyzed:** 849 files

This document provides a comprehensive breakdown of the codebase by analyzing different types of code: UI components, business logic, data access, tests, configuration, and more.

 ... (clipped 314 lines)
scripts/analyze-code-lines.ts [251-341]
function analyzeRepository() {
  const stats = new Map<string, FileStats[]>();
  const rootDir = process.cwd();

  console.log('🔍 Analyzing repository code structure...\n');
  walkDirectory(rootDir, stats);

  // Calculate category totals
  const categoryTotals = new Map<string, CategoryStats>();


 ... (clipped 81 lines)

Solution Walkthrough:

Before:

// scripts/analyze-code-lines.ts
function analyzeRepository() {
  // ... logic to gather stats
  
  console.log('... analysis results ...');
  
  // The script only prints to the console.
  // The markdown file is created and updated manually.
  return { sortedCategories, grandTotal, stats };
}

analyzeRepository();

// docs/CODE_ANALYSIS.md
// This file is manually created and committed to the repository.

After:

// scripts/analyze-code-lines.ts
function generateMarkdownReport(analysisData) {
  const markdownContent = `...`; // Build markdown from data
  fs.writeFileSync('docs/CODE_ANALYSIS.md', markdownContent);
  console.log('Report generated at docs/CODE_ANALYSIS.md');
}

function analyzeRepository() {
  // ... logic to gather stats
  const analysisData = { ... };
  generateMarkdownReport(analysisData);
}

analyzeRepository();

// .gitignore
// docs/CODE_ANALYSIS.md
// The generated report is excluded from version control.
Suggestion importance[1-10]: 9

__

Why: This suggestion addresses a significant architectural flaw in the PR, which is committing a large, manually-updated generated file (docs/CODE_ANALYSIS.md) that will immediately become stale, creating a maintenance burden.

High
General
Exclude report file from analysis

Update the EXCLUDE_FILES set to include 'CODE_ANALYSIS.md' to prevent the
analysis report from being included in its own statistics.

scripts/analyze-code-lines.ts [45-49]

 const EXCLUDE_FILES = new Set([
   'pnpm-lock.yaml',
   'package-lock.json',
   'yarn.lock',
+  'CODE_ANALYSIS.md',
 ]);

Suggestion importance[1-10]: 7

__

Why: This is a valid and important improvement that prevents the analysis script from including its own output, which would skew the metrics on subsequent runs.

Medium
Possible issue
Log errors when file reading fails

In the countLines function, log errors to stderr within the catch block to
notify users when a file cannot be read, instead of failing silently.

scripts/analyze-code-lines.ts [197-204]

 function countLines(filePath: string): number {
   try {
     const content = fs.readFileSync(filePath, 'utf-8');
     return content.split('\n').length;
-  } catch {
+  } catch (error) {
+    console.error(`Error reading file ${filePath}:`, error);
     return 0;
   }
 }
  • Apply / Chat
Suggestion importance[1-10]: 6

__

Why: The suggestion correctly identifies that silent error handling can lead to inaccurate results and proposes logging the error, which improves the script's robustness and debuggability.

@copilot how can we get the generated report and script compliant with the formater:

Run pnpm run format:check

Fixed Prettier formatting issues in commit 5006dcb. Removed trailing spaces from the YAML workflow file and markdown header. All three files now pass pnpm run format:check.
