Security checks across malware telemetry and agentic risk

Overview

This skill is a disclosed Claude cost-analysis helper that uses an Anthropic API key and local configuration review in ways that fit its purpose.

Before installing, be comfortable letting the skill read local OpenClaw prompt/config files and use your Anthropic API key to query Anthropic usage data. Review any proposed diffs before approving changes to openclaw.json or MEMORY.md, and consider using a least-privileged or rotated Anthropic key if available.

Finding
The skill uses both environment access and network access (`ANTHROPIC_API_KEY` and a `curl` call to the Anthropic API), but it does not declare those capabilities as permissions. This creates a transparency and consent problem: users or the hosting platform may not realize the skill can read sensitive credentials and transmit data externally, increasing the risk of unauthorized or surprising data exposure.
