Usage Guidance
This skill appears to do what it says: validate phones, emails, and domains via UpKuaJing and requires only the UPKUAJING_API_KEY and Python. Before installing, consider: (1) API billing — all checks incur fees and the scripts may create payment orders or prompt you to top up; confirm you understand costs before confirming any fee-incurring action. (2) Persistence — the tool will read/write ~/.upkuajing/.env and a version cache under ~/.upkuajing; if you use the built-in 'apply for key' flow it will save a key to that file. (3) Logging — the code can log request/response bodies to ~/.upkuajing/logs if ENABLE_API_LOGGING is turned on; these logs could contain sensitive contact lists, so keep logging disabled or protect that directory. (4) Network activity — the client makes calls to openapi.upkuajing.com for validation and also performs a daily version check (posts skill name) on first API call. If you need more assurance, inspect the code yourself or run the scripts in a restricted environment, and avoid enabling logging if you plan to validate private contact data.
Capability Analysis
Type: OpenClaw Skill
Name: upkuajing-contact-info-validity-check
Version: 1.0.0
The skill bundle provides legitimate contact information validation services (phone, email, domain) via the UpKuaJing API. It manages its own API keys and configuration within a dedicated local directory (~/.upkuajing) and includes safety instructions in SKILL.md requiring user confirmation before performing fee-incurring operations. The code in common.py even demonstrates security awareness by implementing UUID-based path traversal protection for task data management.
Capability Tags
Capability Assessment
Purpose & Capability
Name/description, required env var (UPKUAJING_API_KEY), required binary (python), and the code all align: requests are sent to https://openapi.upkuajing.com and the scripts implement phone/email/domain validation. No unrelated cloud credentials or extraneous capabilities are requested.
Instruction Scope
Runtime instructions stay within scope: they call the published validation APIs and require explicit user-provided inputs. The SKILL.md instructs storing the API key in ~/.upkuajing/.env and to confirm fee-incurring operations. Note: make_request triggers a daily version-check network call (version_check) on first API request, which is unrelated to a single validation call but is documented in code.
Install Mechanism
No download/install spec is provided (instruction-only with included Python scripts). requirements.txt lists a single dependency (httpx). This is proportionate for a Python-based HTTP client. No remote arbitrary binary downloads or extract operations are present.
Credentials
Only UPKUAJING_API_KEY is required (declared as primaryEnv) which is appropriate. The skill reads/writes files under ~/.upkuajing (/.env and version_cache.json) — expected but worth noting because the API key may be persisted to disk by the scripts when using the key-request flow. The code contains an API-logging facility that, if enabled, would log request and response bodies (potentially sensitive contact lists) to ~/.upkuajing/logs; logging is off by default (ENABLE_API_LOGGING = False).
Persistence & Privilege
always:false (no forced inclusion). The skill writes its own files under the user's home (~/.upkuajing) for API key persistence and version cache; this is normal for a CLI-like tool but is persistent filesystem access and should be expected by users. It does not alter other skills or system-wide agent settings.
