Usage Guidance
This skill appears to do exactly what it says: it will send phone numbers you supply to apipick.com and return carrier/geographic info. Before installing or using: (1) confirm you trust apipick.com and review their privacy/terms because phone numbers are personal data; (2) provide a dedicated API key (do not paste broader credentials) and monitor credit/usage since each request costs credits; (3) avoid submitting phone numbers you don’t have consent to share; (4) if the API key is accidentally exposed, revoke/rotate it in apipick’s dashboard. Otherwise the skill’s requirements and instructions are proportionate and coherent.
Capability Analysis
Type: OpenClaw Skill
Name: apipick-china-phone-checker
Version: 1.0.1
The skill bundle is benign, designed to validate Chinese phone numbers via the apipick.com API. All files consistently describe this functionality, requiring an API key from an environment variable (`APIPICK_API_KEY`) or user input. There is no evidence of data exfiltration, malicious execution, persistence mechanisms, or prompt injection attempts in SKILL.md to subvert the agent's intended behavior. The external API call is the core, stated purpose of the skill.
Capability Assessment
Purpose & Capability
The skill name/description match the declared requirements and instructions. The only required credential is APIPICK_API_KEY (primaryEnv), which is exactly what the apipick API requires. No unrelated binaries, config paths, or credentials are requested.
Instruction Scope
SKILL.md explicitly directs the agent to POST a phone_number to https://www.apipick.com/api/check-china-phone and use the x-api-key header sourced from $APIPICK_API_KEY (or ask the user for it). The instructions do not reference other files, system paths, or additional environment variables. Note: using the skill sends phone numbers to apipick.com (expected behavior for this task).
Install Mechanism
No install spec or code is included (instruction-only). Nothing is downloaded or written to disk by the skill package itself, which minimizes installation risk.
Credentials
Only APIPICK_API_KEY is required, which is proportionate and justified by the skill's purpose. No other SECRET/TOKEN/PASSWORD env vars are requested.
Persistence & Privilege
always is false (default). The skill does not request permanent/system-wide presence or modify other skills' configs. It can be invoked by the agent (normal behavior) but has no elevated privileges.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install apipick-china-phone-checker - After installation, invoke the skill by name or use
/apipick-china-phone-checker - Provide required inputs per the skill's parameter spec and get structured output
