Agent Prompt
## Role
Act as a focused technical SEO, AEO, and crawlability remediation expert who can inspect the public page and safely improve the underlying implementation.
## Inputs
- Primary context: Improve nervabio.com at https://nervabio.com.
- Scanner check ID: seo_sitemap_xml.
- Fix title: Publish sitemap.xml.
- Scanner check: sitemap.xml reachability.
- Category: SEO / AEO.
- Status: fail.
- Severity: high.
- Priority: 7; lower numbers are more urgent.
- Score impact: 12 rule points lost.
- Evidence: HTTP 404 returned for sitemap_xml.
- What needs attention: The sitemap file was not reachable.
- Why it matters: A sitemap helps search engines discover the landing page and related public pages sooner.
- Status-specific guidance: A public check reported a failure. Reproduce or inspect the issue first, then make the smallest safe fix.
- Audience or recipient: The site owner, builder, or marketing team responsible for improving this public page.
- Constraints, examples, or source material: Treat the live URL as the public target to inspect, not as the only source of truth. When repository, CMS, or hosting access is available, use that implementation context before changing anything.
- Target outcome: After the fix is deployed and the public page is rescanned, this specific check should improve or pass without lowering other SEO / AEO, security, accessibility, or design signals.
- Likely places to inspect: robots.txt Sitemap directives, static sitemap files, dynamic sitemap routes, sitemap indexes, canonical URL generation, and deployment output; metadata/head configuration, canonical URL logic, robots and sitemap routes, structured data blocks, page copy, headings, and internal navigation; the route, template, component, CMS entry, theme file, or static page that renders the scanned URL; shared layout, metadata, routing, middleware, server, CDN, or hosting configuration if the issue is not in page content; existing tests, build scripts, preview commands, and deployment notes before choosing verification steps.
## Task
Use the provided context to safely complete this workflow: Add /sitemap.xml with your public URLs and confirm it returns HTTP 200.
First reproduce or verify the issue from the public page and available implementation source. Then make the smallest stack-appropriate change that fixes the scanner signal and improves the real user experience.
Use this check-specific implementation guide:
- Provide a reachable sitemap URL with valid urlset or sitemapindex XML. Preserve an existing robots.txt Sitemap directive such as /sitemap_index.xml when it is intentional and valid.
- Include canonical public URLs and avoid localhost, staging, private, noindex, or duplicate URLs.
- Keep all metadata, headings, schema, canonical URLs, and visible copy consistent with the same public facts.
- Use accurate, crawlable, human-visible content as the source for search and answer-engine improvements.
- Keep the implementation stack-appropriate: use the existing framework, CMS, hosting provider, design system, and deployment workflow already in the project.
Acceptance criteria for this fix:
- The sitemap URL declared in robots.txt, or /sitemap.xml when no directive exists, returns HTTP 200 with a valid urlset or sitemapindex root.
- The sitemap contains at least the scanned public page or its canonical equivalent.
- The public URL exposes the corrected crawl/search/answer signal in rendered HTML or reachable public files.
- The change should be visible to a fresh unauthenticated request and likely improve the related FreeScan SEO / AEO check on rescan.
- A fresh FreeScan rescan should show this check improved or passing after deployment.
## Output
Return a structured response with these headings: Findings, Changes Made, Verification Results, Rescan Expectation, Rollback Notes, Assumptions.
## Rules
- Ask a clarifying question when required context is missing.
- Preserve the user's intent and avoid inventing facts.
- Verify the issue exists before changing code or content. If the issue is not reproducible, explain what you checked and recommend no code change.
- If the live URL and implementation source disagree, trust the implementation source for edits and use the live URL only to understand current public behavior.
- Keep the change narrowly scoped to this fix unless another change is required to avoid a regression.
- Match the existing framework, style, design system, routing patterns, and content conventions.
- Preserve existing URLs, forms, analytics, SEO metadata, accessibility semantics, and conversion flows unless the fix explicitly requires changing them.
- Do not perform broad refactors, dependency upgrades, redesigns, rewrites, migrations, file deletions, route changes, or destructive commands unless they are explicitly required and approved.
- Make changes that are easy to review and roll back.
- Prefer editing the canonical source of the page over patching built output, generated files, CDN-cached HTML, or minified assets.
- Do not make a cosmetic or placeholder change just to satisfy the scanner; the public page should be materially better for visitors, crawlers, or assistive technology.
- Verify the result with the smallest reliable test, build, browser check, or manual inspection available.
## Safety
- Do not request, expose, or reproduce sensitive data.
- Redact private details from examples unless the user explicitly says they are safe to include.
- Do not use credentials, cookies, authenticated data, hidden form values, or private response bodies.
- Do not weaken security headers, authentication, authorization, privacy controls, accessibility, or error handling to make the scan pass.Fix rendered layout ergonomics

## Task
Use the provided context to safely complete this workflow: Add /sitemap.xml with your public URLs and confirm it returns HTTP 200.
First reproduce or verify the issue from the public page and available implementation source. Then make the smallest stack-appropriate change that fixes the scanner signal and improves the real user experience.
Use this check-specific implementation guide:
- Provide a reachable sitemap URL with valid urlset or sitemapindex XML. Preserve an existing robots.txt Sitemap directive such as /sitemap_index.xml when it is intentional and valid.
- Include canonical public URLs and avoid localhost, staging, private, noindex, or duplicate URLs.
- Keep all metadata, headings, schema, canonical URLs, and visible copy consistent with the same public facts.
- Use accurate, crawlable, human-visible content as the source for search and answer-engine improvements.
- Keep the implementation stack-appropriate: use the existing framework, CMS, hosting provider, design system, and deployment workflow already in the project.
Acceptance criteria for this fix:
- The sitemap URL declared in robots.txt, or /sitemap.xml when no directive exists, returns HTTP 200 with a valid urlset or sitemapindex root.
- The sitemap contains at least the scanned public page or its canonical equivalent.

- Verify the issue exists before changing code or content. If the issue is not reproducible, explain what you checked and recommend no code change.
- If the live URL and implementation source disagree, trust the implementation source for edits and use the live URL only to understand current public behavior.
- Keep the change narrowly scoped to this fix unless another change is required to avoid a regression.
- Match the existing framework, style, design system, routing patterns, and content conventions.
- Preserve existing URLs, forms, analytics, SEO metadata, accessibility semantics, and conversion flows unless the fix explicitly requires changing them.
- Do not perform broad refactors, dependency upgrades, redesigns, rewrites, migrations, file deletions, route changes, or destructive commands unless they are explicitly required and approved.
- Make changes that are easy to review and roll back.
- Prefer editing the canonical source of the page over patching built output, generated files, CDN-cached HTML, or minified assets.
- Do not make a cosmetic or placeholder change just to satisfy the scanner; the public page should be materially better for visitors, crawlers, or assistive technology.
- Verify the result with the smallest reliable test, build, browser check, or manual inspection available.
## Safety
- Do not request, expose, or reproduce sensitive data.
- Redact private details from examples unless the user explicitly says they are safe to include.
- Do not use credentials, cookies, authenticated data, hidden form values, or private response bodies.
- Do not weaken security headers, authentication, authorization, privacy controls, accessibility, or error handling to make the scan pass.Basic contrast
0/86 of 100 rendered text color sample(s) missed WCAG contrast targets. Worst rendered ratio: 1.
Failed: earned 0 of 8 points.
Priority: Priority 20: lower-risk cleanup after urgent launch blockers.
Why it matters: Low contrast makes a launch page feel less polished and can exclude users with low vision.
Fix: Review key text, buttons, and links against a 4.5:1 contrast target for normal text.
Agent Prompt
## Role
Act as a focused web accessibility remediation expert who can inspect the public page and safely improve the underlying implementation.
## Inputs
- Primary context: Improve nervabio.com at https://nervabio.com.
- Scanner check ID: accessibility_contrast.
- Fix title: Improve detectable color contrast.
- Scanner check: Basic contrast.
- Category: Accessibility.
- Status: fail.
- Severity: medium.
- Priority: 20; lower numbers are more urgent.
- Score impact: 8 of 8 rule points lost.
- Evidence: 6 of 100 rendered text color sample(s) missed WCAG contrast targets. Worst rendered ratio: 1.
- What needs attention: The scanner found text/background color pairs that may be hard to read, or could not verify contrast.
- Why it matters: Low contrast makes a launch page feel less polished and can exclude users with low vision.
- Status-specific guidance: A public check reported a failure. Reproduce or inspect the issue first, then make the smallest safe fix.
- Audience or recipient: The site owner, builder, or marketing team responsible for improving this public page.
- Constraints, examples, or source material: Treat the live URL as the public target to inspect, not as the only source of truth. When repository, CMS, or hosting access is available, use that implementation context before changing anything.
- Target outcome: After the fix is deployed and the public page is rescanned, this specific check should improve or pass without lowering other SEO / AEO, security, accessibility, or design signals.
- Likely places to inspect: CSS variables, design tokens, theme config, text/background combinations, buttons, links, badges, and disabled states; semantic markup, labels, landmarks, headings, focus states, image rendering, form controls, and browser-rendered accessibility output; the route, template, component, CMS entry, theme file, or static page that renders the scanned URL; shared layout, metadata, routing, middleware, server, CDN, or hosting configuration if the issue is not in page content; existing tests, build scripts, preview commands, and deployment notes before choosing verification steps.
## Task
Use the provided context to safely complete this workflow: Review key text, buttons, and links against a 4.5:1 contrast target for normal text.
First reproduce or verify the issue from the public page and available implementation source. Then make the smallest stack-appropriate change that fixes the scanner signal and improves the real user experience.
Use this check-specific implementation guide:
- Adjust foreground/background colors or font treatment where contrast is too low.
- Preserve brand feel while making text readable in real viewport states.
- Fix the semantic or interaction source of the issue rather than hiding warnings with ARIA or visual-only workarounds.
- Keep keyboard, screen reader, and touch users in the verification path.
- Keep the implementation stack-appropriate: use the existing framework, CMS, hosting provider, design system, and deployment workflow already in the project.
Acceptance criteria for this fix:
- Important text and controls meet reasonable contrast targets in rendered states.
- No new low-contrast states are introduced.
- The affected UI remains usable by keyboard and assistive technology and does not introduce heading, label, focus, or contrast regressions.
- The change can be checked in the browser or with an accessibility audit tool when available.
- A fresh FreeScan rescan should show this check improved or passing after deployment.
