Md Web

Render a markdown file as a beautiful, shareable web page in the browser instead of dumping long text in chat. Use when the user wants to preview, view, share, export, or publish markdown as a web page, wants a shareable link to content, or when you need to present long markdown without flooding the conversation. Uploads the file to the user's own S3-compatible storage bucket; the rendered page is publicly accessible via the returned URL.

MD Web - Markdown to Web Page

Upload raw .md files to an S3-compatible storage bucket, where a pre-deployed Docsify server automatically renders them as web pages. This avoids sending long text in the conversation.

When to use this skill

Uploaded content is publicly accessible. Only use this skill when the user explicitly requests it:

• User wants to show or preview content as a web page in a browser
• User wants to generate, export, or publish content as a web page
• User wants a shareable link to content
• User wants output delivered as a web page rather than as long text in chat
• User wants to compile or organize content and present it as a web page
• User invokes this skill by name (e.g., /md-web)

How to use this skill

Step 1: Check configuration

Check if ~/.md-web/config.json exists (cross-platform: use the user's home directory). If it does NOT exist or has empty fields, follow the Configuration section below first.

Step 2: Prepare the markdown file

Either use an existing .md file, or write the content to a temporary file. Choose the temp path based on the current platform (e.g., /tmp/ on Linux/macOS, system temp dir on Windows). Use whichever path works in the current shell environment.

Step 3: Upload via upload.js

bash

node {SKILL_DIR}/upload.js <local-file> <remote-key>

• {SKILL_DIR}: the base directory of this skill (shown at the top when skill is loaded)
• <remote-key>: a descriptive lowercase name with hyphens (e.g., api-docs.md, project-guide.md). A timestamp is prepended automatically to avoid filename collisions.
• On first run, the script auto-detects and deploys Docsify server files. No manual setup needed.

Step 4: Return the result

• On success: the script prints the URL. Reply with only the filename and clickable link. Do NOT paste the markdown content into the chat.
• On failure (non-zero exit code): report the error to the user, then fall back to sending the markdown content as text directly in the chat.

Example success output:

api-docs - https://example.r2.dev/index.html#/md-web/20260305-091500-api-docs

Configuration

This only needs to happen once. On subsequent runs, config.json already exists.

1. Tell the user this skill needs an S3-compatible storage bucket with public access. Point them to {SKILL_DIR}/README.md for detailed setup instructions (Cloudflare R2 / AWS S3 / other S3-compatible services).
2. Ask the user to provide these 5 required fields:
   • access_key: API access key ID
   • secret_key: API secret access key
   • endpoint: S3 endpoint hostname, without https:// (e.g., ACCOUNT_ID.r2.cloudflarestorage.com)
   • bucket: bucket name
   • public_url: public access URL. If the user has a custom domain bound to the bucket, use that (e.g., https://docs.example.com); otherwise use the default R2.dev URL (e.g., https://pub-XXXX.r2.dev). Recommend custom domain for production use — R2.dev URLs have rate limits.
3. Ask about optional settings:
   • region: S3 region. Use auto for Cloudflare R2, or the actual region for AWS S3 (e.g., us-east-1). Default is auto.
   • expire_days: how many days before uploaded markdown files are automatically deleted from the bucket. Default is 30. Set to 0 to keep files forever. The script sets an S3 lifecycle rule scoped to the md-web/ key prefix, so only this skill's own uploads are affected — Docsify server files and any other objects in the bucket are never touched. Note: this requires the API token to have Admin Read & Write permission (not just Object Read & Write). If the token lacks permission, the script will warn but still upload normally — the user can set the lifecycle rule manually in the Cloudflare Dashboard instead.
4. Write the config to ~/.md-web/config.json (create the ~/.md-web/ directory if it doesn't exist). Use the user's home directory ($HOME on Unix, %USERPROFILE% on Windows):

json

{
  "access_key": "...",
  "secret_key": "...",
  "endpoint": "...",
  "bucket": "...",
  "region": "auto",
  "public_url": "...",
  "expire_days": 30
}

5. Then proceed with the upload.

Important notes

• Do NOT generate HTML. Just upload the raw .md file — Docsify handles rendering.
• Do NOT send markdown content to the chat unless upload fails.
• upload.js uses only Node.js built-in modules (zero dependencies).
• All Docsify assets (JS/CSS) are bundled locally — no external CDN dependency at runtime.

External endpoints

This skill connects only to the S3 endpoint configured by the user in config.json. No data is sent to the skill author or any third-party service.

Endpoint	Purpose	Data sent
User's S3 endpoint (config.json → endpoint)	Upload .md files and Docsify server assets	File content, S3 auth headers

Security & privacy

• Anything you upload becomes publicly accessible at the returned URL — never upload secrets, credentials, PII, or other sensitive content.
• Credentials (access_key, secret_key) are stored in plaintext in ~/.md-web/config.json (outside the skill directory, safe from upgrades) and only sent to the user's own S3 endpoint for authentication. Protect this file — don't commit it or share it.
• Use a dedicated bucket. Uploads live under the md-web/ key prefix and the auto-expiry rule is scoped to it, but expire_days: 0 clears the bucket's lifecycle config entirely — a dedicated bucket guarantees the skill never affects unrelated objects or lifecycle rules you set yourself.
• No telemetry, analytics, or data collection by the skill itself.
• upload.js uses only Node.js built-in modules — no third-party dependencies.

By using this skill, markdown content is uploaded to your own S3-compatible storage bucket and made publicly accessible. No data is sent to the skill author or any third-party service. Only install if you trust the storage provider you configure.
