am-will/codex-skills · updated Apr 8, 2026
MDX-style export adds YAML metadata + attribution linking explainx.ai and this canonical listing URL.
Convert any website into clean, extractable Markdown by routing through markdown.new.
- ›Automatically rewrites URLs to prefix them with https://markdown.new/ for cleaner text extraction from docs, blog posts, changelogs, and GitHub issues
- ›Includes a rewrite rule that preserves query parameters, fragments, and schemes while maintaining the original URL structure
- ›Designed for read-only content only; skips markdown.new for authenticated workflows, interactive dashboards, paywalls, and sit
markdown.new URL Prefix
Whenever you need to visit a website URL, you must:
- rewrite it to go through
https://markdown.new/, then - visit the rewritten URL, and
- pull the Markdown content from that page for use in your answer/notes.
Rewrite Rule
- Normalize the destination into an absolute URL with a scheme (
https://preferred). - Prefix it with
https://markdown.new/(do not drop the original scheme).
Examples
https://example.com->https://markdown.new/https://example.comhttps://example.com/docs?a=1#b->https://markdown.new/https://example.com/docs?a=1#bexample.com->https://markdown.new/https://example.com
Agent Workflow (Required)
When you would normally open a website to read it:
- Produce the rewritten
markdown.newURL. - Visit the rewritten URL first (not the original), but only when it is likely to work (see Policy below).
- Extract the page content from the Markdown view (the rendered Markdown and/or the raw Markdown).
- Use that extracted Markdown as the source for summaries, quotes, checklists, or copy/pasteable notes.
If the markdown.new view fails to load or breaks critical functionality, fall back to the original URL for browsing, but still prefer markdown.new for any content extraction if possible.
Policy: When To Use markdown.new (Required)
Do NOT route every site through markdown.new. Use it primarily for "read-only" pages where you want clean, extractable text:
- Documentation pages
- Blog posts / announcements / changelogs
- GitHub issues/PR discussions (when you just need readable text)
- Articles and guides
Skip markdown.new and go straight to the original URL when the destination is likely to be blocked or requires the original site behavior:
- Login, OAuth, checkout, payment, or any authenticated workflow
- Sites that gate content behind JS apps, CAPTCHAs, bot detection, or paywalls
- File uploads, forms, editors, dashboards, interactive widgets
- Anything where cookies/session state must be preserved
Block/Failure Signals (Treat As Blocked)
If you try markdown.new and see any of the below, stop retrying and fall back to the original URL:
- HTTP
401/403/429, "Access denied", "Forbidden", "rate limited" - CAPTCHA / "verify you are human"
- Empty/partial content that clearly does not match the page
- Redirect loops or repeated navigation failures
Fallback Behavior
- Attempt
markdown.newonce when appropriate. - On block/failure, immediately switch to the original URL for browsing.
- If you still need extractable text, try to extract from the original page (reader mode / copy text) and clearly note that
markdown.newwas blocked.
Notes / Exceptions
- Keep this for reading/browsing. For API endpoints, OAuth flows, file uploads, or anything that depends on cookies/login state, use the original URL if the proxy breaks functionality.
- Do not rewrite local paths (
./README.md) or non-HTTP(S) schemes.
Optional CLI Helper
Convert a URL into its markdown.new-prefixed form:
node skills/markdown-url/scripts/markdown-url.js "https://example.com/docs"
How to use markdown-url on Cursor
AI-first code editor with Composer
Prerequisites
Before installing skills in Cursor, ensure your development environment meets these requirements:
- ›Cursor installed and configured on your development machine
- ›Node.js version 16.0+ with npm package manager (verify with
node --version) - ›Active project directory or workspace where you want to add markdown-url
Execute installation command
Execute the skills CLI command in your project's root directory to begin installation:
The skills CLI fetches markdown-url from GitHub repository am-will/codex-skills and configures it for Cursor.
Select Cursor when prompted
The CLI will show a list of available agents. Use arrow keys to navigate and space to select Cursor:
Verify installation
Confirm successful installation by checking the skill directory location:
Reload or restart Cursor to activate markdown-url. Access the skill through slash commands (e.g., /markdown-url) or your agent's skill management interface.
Security & Verification Notice
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your development environment. Always verify the publisher's identity, review recent commits, and test in isolated environments before production deployment.

Use Cases▌
User Story & Requirements Generation
Create detailed user stories, acceptance criteria, and feature specs
Example
Generate user stories for 'password reset feature' with acceptance criteria, edge cases, and test scenarios
Reduce spec writing time by 50%, ensure comprehensive coverage
Competitive Analysis
Research competitors, compare features, identify gaps
Example
Analyze 5 competitor products, create feature comparison matrix, suggest differentiation opportunities
Complete competitive research in 2 hours instead of 2 days
Roadmap Prioritization
Evaluate features using frameworks (RICE, ICE, Kano) and create prioritized backlogs
Example
Score 20 feature ideas using RICE framework, generate prioritized roadmap with rationale
Make data-driven prioritization decisions faster
Stakeholder Communication
Draft PRDs, status updates, and stakeholder presentations
Example
Create executive summary of Q3 roadmap, monthly progress report, feature launch announcement
Save 3-5 hours/week on communication overhead
Implementation Guide▌
Prerequisites
- ›Claude Desktop or compatible AI client
- ›Access to product documentation and roadmap tools (Jira, Notion, etc.)
- ›Understanding of product management frameworks (RICE, Jobs-to-be-Done, etc.)
- ›Stakeholder contact information and communication channels
Time Estimate
30-60 minutes to see productivity improvements
Installation Steps
- 1.Install product management skill
- 2.Start with user story generation for known feature
- 3.Progress to competitive analysis: research 2-3 competitors
- 4.Use for roadmap prioritization: apply RICE/ICE scoring
- 5.Draft stakeholder communications and refine based on feedback
- 6.Build template library for recurring PM tasks
- 7.Share effective prompts with product team
Common Pitfalls
- ⚠Not validating competitive research—verify facts before sharing
- ⚠Accepting user stories without involving engineering team
- ⚠Over-relying on frameworks without qualitative judgment
- ⚠Not customizing outputs to company culture and communication style
- ⚠Skipping stakeholder validation of generated requirements
Best Practices▌
✓ Do
- +Validate research and competitive analysis with real data
- +Collaborate with engineering when generating technical requirements
- +Customize frameworks and templates to your company context
- +Use skill for first drafts, refine with stakeholder input
- +Document successful prompt patterns for PM tasks
- +Combine AI efficiency with human judgment and intuition
✗ Don't
- −Don't publish competitive analysis without fact-checking
- −Don't finalize user stories without engineering review
- −Don't make prioritization decisions solely on AI scoring
- −Don't skip customer validation of generated requirements
- −Don't ignore company-specific context and culture
💡 Pro Tips
- ★Provide context: company goals, constraints, customer feedback
- ★Ask for alternatives: 'Show 3 ways to prioritize this roadmap'
- ★Request stakeholder-specific formatting: 'Executive summary vs. engineering spec'
- ★Use skill for 70% generation + 30% customization to company needs
When to Use This▌
✓ Use When
Use for user story writing, competitive research, roadmap prioritization, stakeholder communication, and PRD drafting. Best for reducing repetitive documentation and research work.
✗ Avoid When
Avoid for strategic product vision (requires deep customer empathy), pricing decisions (needs market and financial expertise), or when face-to-face customer discovery is more valuable than speed.
