/install cheapest-image-generation
Description
Possibly the cheapest AI image generation (~$0.0036/image). Text-to-image via the EvoLink API.
Usage Guidance
Install only if you are comfortable sending image prompts to EvoLink and using an EvoLink API key from your environment. Avoid putting secrets or sensitive personal/business information in prompts, and expect generated images to be saved locally and API credits to be consumed when trigger phrases are used.
Capability Analysis
Type: OpenClaw Skill
Name: cheapest-image-generation
Version: 1.0.2
The OpenClaw AgentSkills bundle for 'cheapest-image-generation' is classified as benign. The `SKILL.md` explicitly highlights 'CRITICAL SECURITY' for output filename sanitization, which is robustly implemented across all reference scripts (`curl_heredoc.md`, `powershell.md`, `python.md`). Filenames are sanitized using `tr -cd 'A-Za-z0-9._-'` (bash) or handled safely via `[System.IO.Path]::GetFullPath` (PowerShell) and `os.path.abspath` (Python). User prompts are safely embedded in JSON payloads using `json_escape` (bash), `ConvertTo-Json` (PowerShell), or `json.dumps` (Python), preventing injection. All network activity is directed to the stated `https://api.evolink.ai` endpoint, and there is no evidence of data exfiltration, backdoor installation, or other malicious intent.
Capability Assessment
Purpose & Capability
The stated purpose is text-to-image generation through EvoLink, and the artifacts only describe submitting prompts, polling task status, downloading the result, and printing a media path.
Instruction Scope
The trigger phrases generate immediately, which is documented and purpose-aligned, but users should understand that this can spend API credits and write an image file without an extra confirmation step.
Install Mechanism
No executable installer or persistence mechanism is present; the package contains markdown instructions and reference implementations.
Credentials
The required EVOLINK_API_KEY is proportionate for a provider-backed image generation skill, and prompts plus the bearer key are sent only to the disclosed EvoLink API endpoint.
Persistence & Privilege
The only persistence is the expected local image output file; there is no evidence of background workers, privilege escalation, profile modification, or unrelated system changes.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install cheapest-image-generation - After installation, invoke the skill by name or use
/cheapest-image-generation - Provide required inputs per the skill's parameter spec and get structured output
