Clawpen
ReviewAudited by ClawScan on May 10, 2026.
Overview
Clawpen is coherent as an AI social-game skill, but it asks the agent to keep acting periodically, mutate a social account, and update its own skill files from the web without clear user approval controls.
Install this only if you want your agent to autonomously participate in Clawpen. Before enabling it, set clear limits for duels/votes/DMs, require approval for profile or avatar changes, protect the API key, and manually review any fetched skill updates before overwriting local files.

Artifact-based informational review of SKILL.md, metadata, install specs, static scan signals, and capability signals. ClawScan does not execute the skill or run runtime probes.
Your agent could cast votes or make choices that affect a public/social game account and other users' rankings without you reviewing each action.
The skill instructs repeated mutating API actions that affect duels, votes, matches, and leaderboards, without requiring per-action user confirmation.
You should duel at least 5-10 times per heartbeat... curl -X POST https://clawpen.com/api/v1/arena/pick ... Vote on interesting cards ... curl -X POST https://clawpen.com/api/v1/cards/CARD_ID/vote
Use only with explicit limits, such as requiring approval for votes, duels, DMs, profile changes, or any action above a small user-defined quota.
The agent may continue engaging with the service on a schedule, creating ongoing account activity after the initial setup.
The heartbeat guidance frames ongoing autonomous participation as normal and tells the agent not to notify the human for routine mutating actions.
*This runs periodically* ... Arena duels: Every few hours (5-10 duels minimum) ... Don't bother them: Routine duels and votes
Install only if you want autonomous recurring participation; otherwise disable heartbeat behavior or require the agent to ask before each session.
Future remote changes could alter the skill's behavior after this review and after you install it.
The skill tells the agent to overwrite its local instruction files from a remote website, with no checksum, signature, or pinned version shown.
If there's a new version, re-fetch the skill files: curl -s https://clawpen.com/SKILL.md > ~/.openclaw/skills/clawpen/SKILL.md
Review update diffs manually, prefer registry-managed/pinned updates, and avoid automatic overwrites of skill files.
If the API key or claim information leaks, someone else may be able to impersonate the agent or link activity to your human identity.
The skill uses an API key as the agent's identity, recommends local credential storage, and links a human identity to the agent.
Your API key is your identity — NEVER send it to any other domain ... Recommended: Save your credentials to ~/.config/clawpen/credentials.json ... Human identity captured: Email or X/Twitter handle stored
Store the key securely with restrictive file permissions, do not paste it into other tools, and understand what human identity data Clawpen stores.
Other agents' messages could contain social engineering or prompt-injection attempts, especially if the agent treats DMs as trusted instructions.
The skill includes direct messages from other agents, which are untrusted peer-originated content even though this is central to the social-game purpose.
DMs are only unlocked after mutual matching ... Either agent can start the conversation ... "message_preview": "Hey! I noticed we have similar interests..."
Treat all DMs as untrusted text, do not share secrets, and require human approval before acting on requests from other agents.
