Summary by cubic

Adds the netlify-website-optimizer check to audit Netlify preview vs production deploys for bundle size regressions and common perf misconfigurations. Blocks merges on critical issues and posts concise reports with recommendations.

• New Features
  • Quick triage: <10% change auto-approve, 10–50% request review, >50% block.
  • Compares JS/CSS/image totals between production and preview deploys via netlify/netlify-mcp.
  • Flags config problems: disabled minification/tree-shaking, production sourcemaps, missing cache headers.
  • Provides ready-to-use report templates for minor, significant, and critical changes.
  • Blocking criteria: >50% bundle increase or any critical config issue.
  • Customizable via .continue/checks/netlify-website-optimizer.md.

Pull Request Overview

The PR introduces a useful LLM-based agent for auditing Netlify deploys, and Codacy reports that the changes are up to standards. However, there are a few critical issues that must be addressed before merging:

• Startup Failure: The model identifier anthropic/claude-sonnet-4-5 is invalid, which will cause the check to fail immediately upon initialization.
• Functional Gaps: The current asset discovery logic fails to identify CSS files (which use href) and images. This directly contradicts the acceptance criteria for calculating total bundle sizes including images.
• Tooling Incompatibility: There is a mismatch in expected MCP tool naming (snake_case vs kebab-case) and a non-actionable instruction for the agent to 'wait', which may lead to inefficient execution loops.

Test suggestions

• Verify triage logic: PRs with <10% size increase are marked as APPROVED.
• Verify asset discovery: Correctly identify JS and CSS assets from the HTML source.
• Verify image discovery: Correctly identify image assets (.png, .jpg, etc.) for size comparison.
• Verify blocking logic: PRs with >50% size increase or 'minify: false' are marked as BLOCKED.
• Verify configuration audit: Correctly identify missing or 'no-cache' headers in netlify.toml.
• Verify discovery of CSS assets linked via 'href' attributes in tags.

Prompt proposal for missing tests

Consider implementing these tests if applicable:
1. Verify image discovery: Correctly identify image assets (.png, .jpg, etc.) for size comparison.
2. Verify discovery of CSS assets linked via 'href' attributes in <link> tags.

Low confidence findings

• The current strategy of using 'curl -sI' for every individual asset discovered may be inefficient for websites with a high volume of assets. While functional for small sites, consider if the Netlify MCP provides a more efficient way to fetch metadata for multiple files in a single call.

_{🔴 HIGH RISK}

The asset extraction logic needs to be significantly more robust to meet the PR requirements. It currently misses CSS files (referenced via href), images (which are required for the bundle size audit), and assets with query parameters (e.g., main.js?v=1.2).

Suggested change

	grep -oP 'src="[^"]+(\.js|\.css)"' index.html
	grep -oP '(src|href)=["\'][^"\']+\.(js|css|png|jpg|jpeg|svg|webp)(\?[^"\']*)?["\']' index.html

_{🔴 HIGH RISK}

The model identifier anthropic/claude-sonnet-4-5 is invalid. The current available models are claude-3-5-sonnet or claude-3-opus.

Suggested change

	model: anthropic/claude-sonnet-4-5
	model: anthropic/claude-3-5-sonnet

_{⚪ LOW RISK}

Suggestion: The LLM agent does not have a native 'sleep' or 'wait' utility. Instructing it to wait 30s may cause it to enter a busy-loop or hallucinate a tool. Suggest instructing the agent to inform the user that the build is in progress and prompt for a manual retry.
