GargantuaX/gemini-watermark-remover is a JavaScript tool that removes watermarks from Gemini-generated images and videos using reverse alpha blending rather than AI inpainting. It supports local processing in browsers or Node.js, with browser, extension, userscript, command-line, and automation use cases. The catalogue skill helps coding agents use the remover in scripted workflows.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.06834 | $0.06834 |
| Opus 5.5 | $0.02734 | $0.02734 |
| Sonnet 5.5 | $0.01367 | $0.01367 |
| Haiku 4.5 | $0.00683 | $0.00683 |
Grade A, and why
gemini-watermark-remover AGENTS.md scanned grade A with 0 findings 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 1mo ago.
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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 430 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Best-Effort Product Principle
- Treat best-effort processing as the minimum product guarantee: when the input is available and processing can run, return the best result the current system can produce.
- A result with visible residuals or minor imperfections is preferable to returning the unchanged input or no result.
- Low confidence, incomplete catalog coverage, or a quality warning should not by themselves block output. Use the most plausible validated/fallback strategy, produce the result, and surface the uncertainty as non-blocking metadata or UI copy.
- Do not tell users to refresh or retry when repeating the same action is not expected to change the outcome. Retry guidance is allowed only when there is a concrete, recoverable state change and the user can take an actionable step.
- Reserve hard failure for cases where processing truly cannot run or no usable input/output can be produced; do not use failure as a substitute for a best-effort result.
Debug Workflow
Supported Sample Scope
- Quality fixes target original Gemini outputs. Inputs with repeated watermarking, screenshots, or subsequent image edits are outside the required support scope; do not add special processing solely to accommodate them.
- Classify sample provenance separately from processing quality. Keep confirmed edited exports as observations, with the evidence for exclusion; retain unknown provenance as unknown. Neither unusual dimensions, missing metadata, nor poor removal quality establishes editing history.
- An unknown-source upload can motivate an investigation, but does not by itself establish a defect in supported original outputs. Reproduce the suspected issue on a verified original or a controlled fixture before promoting a fix. Do not silently relabel unresolved samples as passing or edited to satisfy a release gate.
- This scope is an investigation and acceptance rule, not a new runtime rejection rule. Preserve existing best-effort behavior and content-damage regression controls.
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.

gemini-watermark-remover AGENTS.md is an instructions file published in the GitHub repository GargantuaX/gemini-watermark-remover (5,716 stars, last pushed 11d ago), licensed MIT. It adds 6,834 tokens to every session, about $0.0273 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
