Description
Remove image backgrounds using the remove.bg API with API-key auth and transparent PNG output. Use when high-quality cutouts are needed and cloud processing...
Usage Guidance
This skill appears to do exactly what it says: it validates an input image (type/size/dimensions), then uploads it to remove.bg using REMOVE_BG_API_KEY and saves the returned file under outputs/removebg-api. Before installing, ensure you: 1) have and trust a remove.bg account (uploads consume quota/credits and send image data to remove.bg), 2) store REMOVE_BG_API_KEY securely in OpenClaw config, 3) have python3 and whatever 'uv' runner referenced in examples available if you plan to use the preferred command, and 4) test with non-sensitive images first. Note the script will use OPENCLAW_WORKSPACE if present to find the workspace root (this is optional but not declared as required). If you need absolute assurance, review the script (scripts/removebg_api.py) yourself — it uses a single hard-coded API endpoint and standard Python urllib; there are no obfuscated or alternate network endpoints.
Capability Analysis
Type: OpenClaw Skill
Name: removebg-api
Version: 1.0.1
The removebg-api skill is a well-implemented tool for removing image backgrounds using the remove.bg API. The script (scripts/removebg_api.py) includes robust security measures, such as path traversal prevention by ensuring all file operations occur within the OpenClaw workspace, magic-byte validation to verify image formats (PNG, JPEG, WEBP), and strict file size and dimension limits. No indicators of data exfiltration, malicious execution, or prompt injection were found.
Capability Assessment
Purpose & Capability
Name/description, required env var (REMOVE_BG_API_KEY), and the included Python script all match a remove.bg API integration. Required binaries (python3 and 'uv' used by examples) are reasonable for running the script. No unrelated credentials or services are requested.
Instruction Scope
Runtime instructions and the Python script are narrowly scoped: they validate file extension and magic bytes, enforce size/dimension limits, restrict input to the workspace and output to outputs/removebg-api, and only POST the image to https://api.remove.bg/v1.0/removebg. One minor mismatch: the script optionally reads OPENCLAW_WORKSPACE to locate the workspace but OPENCLAW_WORKSPACE is not listed in required env metadata — its use is optional and not necessary for normal operation.
Install Mechanism
No install spec is included (instruction-only plus a local script), so nothing is downloaded or installed automatically. This is the lowest-risk install model.
Credentials
Only REMOVE_BG_API_KEY is required and declared as the primary credential; that is proportional to a service that authenticates via API key. The script uses that key to call remove.bg and does not request additional secrets. It will also check OPENCLAW_WORKSPACE if present (optional).
Persistence & Privilege
always is false and the skill does not modify other skills or system-wide settings. It does not request persistent elevated privileges or write outside its workspace output directory.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install removebg-api - After installation, invoke the skill by name or use
/removebg-api - Provide required inputs per the skill's parameter spec and get structured output
Version History
v1.0.1

v0.1.2
Security hardening: enforce workspace path sandbox, image-only input validation (extension + magic bytes), size/dimension limits, remove unsafe path bypass, and update docs.
v0.1.1
Polish docs: config-managed API key as primary setup, removed env-file fallback, uv-first usage
v0.1.0
Initial release: remove.bg API skill with required env metadata, uv-first usage, and config-managed key guidance
