Claude Watermark

Claude Watermark

Use the hosted Claude Watermark service through the CLI bundled beside this file at cli/bin/claude-watermark.mjs. Resolve this Skill's installed directory and invoke the CLI with Node. The Skill installation is sufficient: do not configure MCP or install another package.

Workflow

1. Take text from the current conversation, selection, or named file. Never ask the user to paste text that is already accessible.
2. Run node <skill-dir>/cli/bin/claude-watermark.mjs auth status --json.
3. If unauthenticated, run the same CLI with auth login. Tell the user to approve the browser page while the command waits, then continue the original request.
4. For a file, use rewrite --file <path> --json. Otherwise send the exact text through stdin to rewrite --json; never put user text in a shell argument.
5. Return the text field directly. Mention credits only when useful or requested.

Add only requested flags: --tone, --strength, --preserve-citations, --normalize-quotes, or --replace-em-dashes.

Never rewrite locally as a fallback, expose credentials, or claim that deterministic cleanup removed a statistical watermark.

Errors

• insufficient_credits: report shortfall and topUpUrl. After top-up, retry without asking the user to resend text.
• unauthenticated: run auth login; never ask for a password or access token.
• Rate limit, oversized input, or provider failure: relay the actionable message and any refund statement.
