DropFiles

Upload HTML or Markdown content to the DropFiles service and return a public shareable link. The service is free, globally accessible, and hosted on Cloudflare's edge network.

When to Invoke

Invoke this skill when the user wants to:

• Share generated HTML or Markdown content via a public link
• Publish a document, report, or page and get a URL to distribute
• Upload any text-based artifact (HTML/Markdown) for online viewing
• Generate a shareable preview link for content the agent just produced

How to Upload

Use the bundled wrapper script. Do NOT construct curl commands or JSON payloads manually.

python3 scripts/upload.py [OPTIONS]

The script handles content reading, JSON serialization, temp-file management, curl invocation (Cloudflare WAF blocks non-curl HTTP clients), response parsing, and temp-file cleanup. Run python3 scripts/upload.py --help for the full interface.

Content Source (priority: --file > --content > stdin)

• stdin (preferred for piped content): cat file.md | python3 scripts/upload.py --json
• --file PATH: python3 scripts/upload.py --file report.md --json
• --content TEXT: only for short inline content

Options

Option	Values	Default	Notes
--type	html | markdown | auto	auto	auto detects HTML by <html / <!doctype prefix, else Markdown.
--expire	1h | 1d | 7d | 30d	7d	Link lifetime.
--title	string	—	Optional title shown on the share page.
--lang	en | zh | auto	auto	Language hint for the share page.
--json	flag	off	Output full JSON response (recommended for agents). Without it, prints human-readable URL: / Preview: / Expires: lines.

Password Policy

The default is no password — the share link is publicly accessible by anyone with the URL.

• No password (default): omit both password flags.
• User-supplied password: pass --password "the password".
• Skill-generated 6-digit password: pass --generate-password. The script generates a random 6-digit numeric code (e.g. 482917), includes it in the upload, and surfaces it in the output. Always relay the generated password back to the user so they can share it with viewers.

Workflow

1. Confirm the content to upload (HTML or Markdown). If the user just generated a document/page, use that content directly — write it to a temp file or pipe via stdin.
2. Determine options:
   • type: use auto unless the user specifies.
   • expire: default 7d unless the user requests a different lifetime.
   • title: optional, set if the user provides one.
3. Determine password:
   • Default: no password.
   • If the user explicitly provides a password, pass it via --password.
   • If the user asks for protection without providing a password, pass --generate-password.
4. Call the wrapper script (use --json for reliable parsing):

   python3 scripts/upload.py --file content.html --type html --expire 7d --json
   

5. Parse the JSON output:
   • On success: {"success": true, "data": {"url": "...", "preview_url": "...", "expire_at": "...", ...}} (plus a top-level password field if --generate-password was used).
   • On failure: {"success": false, "error": {"code": "...", "message": "..."}}.
6. Return the url (and preview_url if relevant) to the user. If a password was generated, prominently display it: Generated password: XXXXXX.
7. On error, surface error.message to the user and suggest fixes (see error codes below).

Error Codes

Code	Meaning
CONTENT_REQUIRED	content field is empty.
CONTENT_TOO_LARGE	Content exceeds 5 MB.
INVALID_TYPE	type is not html / markdown / auto.
INVALID_EXPIRE	expire is not 1h / 1d / 7d / 30d.
RATE_LIMIT_EXCEEDED	Too many requests from the same IP — wait and retry.
NETWORK_ERROR	curl could not reach the server (local script-side).
PARSE_ERROR	Response could not be parsed (local script-side).

Limits

• Max content size: 5 MB (UTF-8 bytes).
• Max expiry: 30 days.
• Rate limiting applies per IP; if you hit RATE_LIMIT_EXCEEDED, wait and retry.

Notes

• The share link is public (unless password-protected). Anyone with the URL can view the content.
• Viewers do not need an account.
• HTML content is sanitized server-side: <script> tags and event handlers are removed.
• Markdown supports standard GitHub-flavored Markdown including code blocks, tables, and images.
• The preview_url adds ?preview=1 and is useful when embedding the link in a context that should not inflate the access counter on initial load.
