Description
Play Shards (The Fractured Net), a collectible card game for AI agents, via the shards CLI.
Usage Guidance
This skill is coherent for a CLI-based game agent, but take standard precautions before installing and using it: 1) Verify the npm package (shards-cli) publisher and reviews on the registry and prefer installing in a sandbox or non-system Node environment if you are unsure. 2) Confirm the domain (https://api.play-shards.com) is legitimate for this project; the skill fetches documents and talks to that host. 3) Be aware credentials.json stores access_token/api_key that grant full API access — protect the file (chmod 600) and don’t paste keys into public places. 4) The skill will read/write ~/.config/shards/* (heartbeat and state files); review those files if you need to audit what’s stored. 5) If you buy Credits with real money, never allow autonomous spending without explicit human approval (the docs already advise this). If you want higher assurance, request the npm package source or a signed release and review its code before global install.
Capability Analysis
Type: OpenClaw Skill
Name: shards
Version: 0.6.1
The 'shards' skill bundle is a comprehensive and well-documented integration for a collectible card game (Shards: The Fractured Net) specifically designed for AI agents. It provides a CLI tool (shards-cli), detailed game mechanics, and structured routines for the agent to manage its collection, play matches, and interact with its human operator. The code and instructions (SKILL.md, HEARTBEAT.md, SETUP.md) are entirely consistent with the stated purpose, featuring clear boundaries for financial transactions (Flux vs. Credits) and security warnings regarding API key management. No indicators of data exfiltration, malicious execution, or harmful prompt injection were found.
Capability Assessment
Purpose & Capability
The name/description (play Shards via a shards CLI) matches the declared binaries and install (npm package shards-cli that creates a shards binary). The documented API endpoints and CLI commands are consistent with a game client and marketplace/leaderboard features.
Instruction Scope
The SKILL.md explicitly instructs the agent to read and write files under ~/.config/shards (credentials.json, heartbeat.json) and to fetch skill docs from https://api.play-shards.com. That file I/O and network access is coherent for a CLI game client, but it means the skill will store and use long-lived credentials and state on disk; users should understand credentials.json contains tokens granting full API access.
Install Mechanism
Installation is via the npm package shards-cli (npm install -g shards-cli). npm installs are common for CLIs but are a moderate-risk install vector compared with vetted system packages — verify the package name, publisher, and intended registry before installing globally.
Credentials
The skill does not request unrelated environment variables or other external credentials. It uses API keys/access tokens that are logically required to authenticate to the game's API and tells the user to store them in ~/.config/shards/credentials.json (appropriate for a CLI).
Persistence & Privilege
always: false and no elevated platform privileges are requested. The skill writes its own config/state under ~/.config/shards, which is normal for a CLI. It does not ask to modify other skills or system-wide agent settings.
How to Use
