Usage Guidance
Before installing or providing an API key: 1) Verify the skill's origin — there is no homepage or source repository listed; prefer skills with a known owner or public repo. 2) Confirm the platform will store COINMETA_API_KEY securely and that you will only provide a key scoped to CoinMeta (do not reuse high-privilege or cross-service keys). 3) Ask the publisher to reconcile the manifest inconsistency (registry shows no required env/bins but SKILL.md requires COINMETA_API_KEY and curl). 4) Test the skill in a sandbox account/key first to confirm it only calls the documented CoinMeta endpoints (note the api.coinmeta.com vs www.coinmeta.com discrepancy and ask the author to clarify). 5) If you cannot verify the vendor or reveal a safe test key, do not provide secrets — you can still evaluate informational behavior by inspecting logs or running equivalent curl commands manually.
Capability Analysis
Type: OpenClaw Skill
Name: coinmeta-skill
Version: 1.0.2
The coinmeta skill bundle is a standard API wrapper for querying cryptocurrency news and articles from api.coinmeta.com. It uses curl to perform authenticated POST requests and provides clear instructions for the agent to parse JSON responses and handle errors, with no evidence of malicious intent, data exfiltration, or prompt injection.

Capability Assessment
Purpose & Capability
The SKILL.md describes exactly the behavior advertised (querying CoinMeta endpoints for newsflashes and articles). Requiring an API key (COINMETA_API_KEY) and curl is proportional to the task. However, the registry-level summary provided with the skill lists no required env vars or binaries while SKILL.md declares both COINMETA_API_KEY and curl — this metadata mismatch is unexpected and reduces confidence.
Instruction Scope
Instructions are narrowly scoped to making POST requests to specific CoinMeta endpoints, parsing timestamps, and stripping HTML from content. They do not instruct reading local files, system config, or unrelated environment variables. Minor issue: endpoints use two domains (api.coinmeta.com vs www.coinmeta.com) which looks like an inconsistency/typo but not necessarily malicious.
Install Mechanism
This is instruction-only with no install spec or code files, so nothing is written to disk by the skill itself. Runtime requires curl to be present; no third-party packages or downloads are requested.
Credentials
SKILL.md declares COINMETA_API_KEY as primaryEnv (reasonable for an API client). But the registry metadata provided above states 'Required env vars: none' — that inconsistency is concerning because it could mean the manifest shown to the platform or user is incomplete or out of sync. The skill asks for a single API key only (no unrelated credentials), which is proportionate if the key is only for CoinMeta, but verify the platform prompts/labels this key clearly and that you don't reuse sensitive keys from other services.
Persistence & Privilege
Skill flags show no elevated persistence (always: false). It is user-invocable and may be called autonomously by the agent (default), which is expected for skills. The skill does not request modification of other skills or system-wide configuration.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install coinmeta-skill - After installation, invoke the skill by name or use
/coinmeta-skill - Provide required inputs per the skill's parameter spec and get structured output
