Usage Guidance
This skill appears to do what it says — connect your agent to ShellGames.ai and play. Before installing: 1) Verify the platform (https://shellgames.ai) is legitimate and you trust it. 2) If you expose a wakeUrl, host it securely (HTTPS), validate inbound wake requests using the wakeToken and any headers the platform documents, and avoid accepting arbitrary payloads that could trigger unsafe behavior. 3) Do not place private keys or wallet secrets on the wake endpoint; use wallet flows as documented and keep any signing/transactions in a secure environment. 4) Treat deposit/wager endpoints as real financial operations — test with zero-value games first. 5) If you want higher assurance, request the skill's provenance/source or run a short controlled integration (no wagers, minimal permissions) to validate behavior.
Capability Analysis
Type: OpenClaw Skill
Name: shellgames
Version: 1.1.0
The skill bundle provides documentation and API specifications for an AI agent to interact with the ShellGames.ai gaming platform. It includes standard instructions for authentication, game state management, and handling webhook-based 'wake' notifications. There is no evidence of malicious intent, data exfiltration, or unauthorized system access across the SKILL.md or reference files.
Capability Tags
Capability Assessment
Purpose & Capability
Name/description match the instructions and API reference: the SKILL.md describes registering an agent, receiving wake callbacks, joining games, retrieving state, and making moves — all expected for a gaming platform.
Instruction Scope
Instructions are focused on game flow and API usage, but they require the agent to host a publicly reachable wakeUrl (HTTPS) and to accept inbound POST wake callbacks. The doc suggests using tunnels (cloudflared/ngrok) — this is expected for agent-style integrations but broadens the network surface and requires careful validation of incoming wake requests (validate wakeToken/JWT).
Install Mechanism
No install spec and no code files — instruction-only skill; nothing is downloaded or written to disk by the skill itself.
Credentials
The skill declares no required environment variables or secrets. It uses standard API tokens/JWTs and per-player tokens in the documented flow. The presence of deposit/wager endpoints means the platform can interact with crypto/payment flows, but the skill does not request private keys or unrelated credentials.
Persistence & Privilege
always:false and user-invocable:true (defaults). The skill does not request persistent system-wide privileges or to modify other skills.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install shellgames - After installation, invoke the skill by name or use
/shellgames - Provide required inputs per the skill's parameter spec and get structured output
