功能描述

Remove image watermarks with the Nowatermark.info API, request polling, request_id resume, and public image URL validation.

使用说明 (SKILL.md)

Image Watermark Remover

Remove watermarks from public image URLs through the Nowatermark.info API.

When to Use

Use this skill when the user wants to remove a watermark from an image they are authorized to edit, resume an existing request_id, or check the status of a prior cleanup job.

Quick Reference

Topic	File
API key setup, input rules, and commands	`setup.md`
Endpoints, payloads, responses, and error codes	`references/api.md`
Submit-and-poll helper script	`scripts/remove_watermark.py`

External Endpoints

Method	Endpoint	Purpose	Data sent
`POST`	`https://nowatermark.info/api/image/remove-watermark`	Submit watermark-removal job	`file_url`
`POST`	`https://nowatermark.info/api/jobs/query`	Query job status	`request_id`

Data Storage

Do not create, download, or overwrite local files unless the user asks first. Ask the user before saving API responses or downloading the cleaned image.

Security & Privacy

Ask the user to confirm they are allowed to edit the image when ownership or permission is unclear.
Tell the user that the public image URL is sent to nowatermark.info for processing.
Request the API key through environment or skill settings; do not expose NOWATERMARK_API_KEY in logs or replies.
Prefer public image URLs over local file handling to minimize local data movement.

Core Rules

If ownership or permission is unclear, ask the user to confirm they are allowed to edit the image before sending requests.
Verify NOWATERMARK_API_KEY is available before sending requests.
Require a direct public image URL; reject local paths, page URLs, and expiring signed URLs.
Prefer scripts/remove_watermark.py for submit-plus-poll workflows.
Poll every 3-5 seconds until completed or failed, then return the final url or the failure details.
Reuse a supplied request_id for status checks instead of creating a duplicate job.

安全使用建议

This skill appears coherent and limited to calling nowatermark.info using your NOWATERMARK_API_KEY. Before installing: (1) confirm you have the legal right to remove the watermark for any image you submit; (2) only supply an API key obtained from https://nowatermark.info and do not paste it into public chat; (3) avoid changing the default base URL — the script lets callers override --base-url, which would cause your API key to be sent to that host (use only trusted endpoints); (4) the script prints API responses (not the API key), and will not download or save images unless you ask it to—ask the skill to confirm before saving downloaded results.

功能分析

Type: OpenClaw Skill Name: image-watermark-remover Version: 1.0.0 The skill provides a legitimate interface for removing image watermarks using the Nowatermark.info API. The Python script (scripts/remove_watermark.py) uses standard libraries to submit image URLs and poll for results, with no evidence of data exfiltration, unauthorized file access, or malicious execution. The instructions in SKILL.md include proactive security measures, such as advising the agent not to log API keys and to verify user permissions before processing images.

✓ Purpose & Capability

Name/description, required env var (NOWATERMARK_API_KEY), endpoints in references/api.md, SKILL.md rules, and the bundled Python script all align with a simple submit-and-poll integration with nowatermark.info. No unrelated credentials or binaries are requested.

ℹ Instruction Scope

Runtime instructions stay within the described purpose (submit public image URL, poll status, return result). The script and SKILL.md explicitly avoid local-file operations unless the user asks. One notable behavior: the Python script accepts a --base-url override, so if an operator passes a different base URL it will send the API key and payload to that host. This is useful for testing but should be treated carefully to avoid accidentally sending the API key to a malicious endpoint.

✓ Install Mechanism

No install spec; this is an instruction-only skill with a small helper script included. Nothing is downloaded from external hosts during install and no archives are extracted.

✓ Credentials

Only a single service credential is required (NOWATERMARK_API_KEY), which is proportional to the described API integration. The SKILL.md also instructs not to log or expose the key. No other secrets or unrelated environment variables are requested.

✓ Persistence & Privilege

The skill is not always-enabled and does not request system-wide configuration changes or access to other skills' credentials. It does not persist itself beyond its included files.
