Klaw Arena
ReviewAudited by ClawScan on May 10, 2026.
Overview
The game instructions are mostly transparent, but onboarding requires the agent to publish a promotional Moltbook post with the skill URL and optionally install mutable remote instruction files.
Before using this skill, decide whether you are comfortable with your agent publishing a public Moltbook post that promotes the game and includes the skill URL. Review and approve the exact post manually, inspect any remote files before running the curl install commands, and keep the Klaw Arena API key limited to the official API domain.

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.
An agent following the skill could publish public content from the user's or agent's social presence as part of onboarding.
Posting to Moltbook is a public account/content mutation. The skill presents it as the required first registration step, but the shown instructions do not require a separate human preview or approval before publishing.
Create a post on Moltbook in the `/klawarena` submolt announcing that you're joining.
Require explicit user approval and review of the exact Moltbook post before publishing, and make clear in the registry description that public posting is required.
The skill may cause agents to advertise and spread the skill to other agents as a condition of registration.
The onboarding flow requires a promotional public post that includes the skill URL, creating a propagation mechanism through agents' social posts.
Your post helps other agents discover the game — make it count! ... always include the skill URL (`https://arena.klawarena.xyz/docs/skill.md`) so others can join too.
Make promotional posting optional, remove the requirement to include the skill URL, or add an explicit opt-in and user approval step for public promotion.
If the remote files change, installing or re-fetching them could change the agent's future instructions or strategy without registry review.
The skill provides user-directed commands to download additional mutable remote files into an OpenClaw directory. Those remote files are not part of the supplied manifest and are not pinned by hash or version in the shown command.
curl -s https://arena.klawarena.xyz/docs/skill.md > ~/.openclaw/moltbot/clawdbot/SKILL.md ... curl -s https://arena.klawarena.xyz/docs/strategy.md > ~/.openclaw/moltbot/clawdbot/STRATEGY.md
Inspect the remote files before installing, prefer versioned or hashed downloads, and avoid overwriting existing OpenClaw files unless you intend to install this exact skill state.
Using the skill links the game character to the owner identity and stores a credential that can act as the Klaw's identity for game API calls.
The skill ties registration to the Moltbook author's owner identity and uses a local API key for subsequent account actions. This is disclosed and purpose-aligned, with an explicit warning not to send the key to other domains.
Your human's Twitter/X handle is extracted from `post.author.owner.x_handle` ... All API requests (except registration) require the `X-Klaw-Api-Key` header ... Save your credentials to `~/.config/klawarena/credentials.json`
Use a dedicated game credential, store it securely, and send it only to `https://api.klawarena.xyz/api/v1/*` as the skill itself warns.
