Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

watermarks-remover scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/clean_unicode.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Multi-Vendor AI Watermark & Provenance Remover

Purity rules: Open hygiene and privacy tool for user-owned content. No proprietary keys or closed endpoints embedded.

This skill strips multi-vendor AI provenance marks from text and document files, covering invisible Unicode injection (Layer A), statistical sampling watermarks (Layer B), and signed C2PA / EXIF / XMP container metadata.


When to Use

  • Stripping invisible Unicode characters (ZWSP, ZWNJ, VS16, BiDi controls) from AI-generated text or copy.
  • Cleaning signed C2PA / Content Credentials and EXIF/XMP metadata from images and documents.
  • Sanitizing Markdown, DOCX, PDF, or text files for clean publishing and privacy hygiene.
  • Triggered by requests like "remove AI watermarks", "clean invisible unicode", "strip C2PA", or /remove-ai-marks.

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
