Description
Generate social images and OG cards from professional templates via the SnapOG API. One API call = one pixel-perfect PNG.
Usage Guidance
This skill appears to do exactly what it says: call the SnapOG API using SNAPOG_API_KEY to generate images. Before installing: (1) keep your SNAPOG_API_KEY secret (don’t paste it into public repos or share it), (2) be cautious when using webhook_url or creating signed URLs — only point webhooks to trusted endpoints and keep signed-URL expirations short so you don't unintentionally publish private content, (3) verify you trust https://snapog.dev (check their docs/TOS/privacy) since generated assets and parameters will be sent to that service, and (4) rotate the API key if you suspect it was exposed. Overall there are no incoherent or disproportionate requirements in this skill.
Capability Analysis
Type: OpenClaw Skill
Name: snapog
Version: 1.0.0
The skill is designed to interact with the SnapOG API for image generation, requiring an API key. While the instructions in SKILL.md are descriptive and functional, the API's `/v1/generate` endpoint includes a `webhook_url` parameter. This parameter allows the agent to specify an arbitrary URL to POST to upon generation completion, presenting a significant prompt injection vulnerability. An attacker could potentially instruct the AI agent to use this feature to exfiltrate data or trigger actions on an attacker-controlled server, even though the skill itself does not explicitly instruct malicious use.
Capability Assessment
Purpose & Capability
Name/description (generate OG/social images) matches the requirements and runtime instructions. The only required secret is SNAPOG_API_KEY which is appropriate for an API-backed image generation service.
Instruction Scope
SKILL.md instructs the agent to call the SnapOG API and to read SNAPOG_API_KEY from the environment — this is expected. The docs also mention features that can transmit results externally (webhook_url and creating signed URLs that work without auth). These are API features (not hidden agent behavior) but are worth noting because a user could accidentally expose generated images or create signed URLs with too-long expiry or point webhooks at attacker-controlled endpoints.
Install Mechanism
No install spec and no code files — instruction-only skill. Nothing is downloaded or written to disk by the skill itself.
Credentials
Only SNAPOG_API_KEY is required and declared as the primary credential. That is proportionate to the stated functionality; no unrelated secrets or config paths are requested.
Persistence & Privilege
always is false and the skill does not request persistent system presence or modify other skills. Agent autonomous invocation is allowed by default but is not combined with any elevated privileges here.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install snapog - After installation, invoke the skill by name or use
/snapog - Provide required inputs per the skill's parameter spec and get structured output
