Sar Calculator

Calculate SAR indicator, analyze A-share trends, price position, volume ratio, momentum, and provide a four-dimensional score and trading suggestion.

Security Scan

The skill's code and instructions match its stated purpose (fetch Baostock data and compute SAR-based scores); nothing in the files indicates secret exfiltration or unrelated privileges.

Purpose & Capability

Name/description (SAR calculator for A-share analysis) align with the code and SKILL.md: it uses the Baostock client and pandas/numpy to fetch historical K-line data and compute SAR, volume ratio, momentum, and scores. No unrelated credentials, binaries, or services are requested.

Instruction Scope

Runtime instructions only direct the agent/user to run the provided Python script and to install baostock/pandas. The script only calls Baostock APIs and performs local computations; it does not read unrelated system files or transmit data to unexpected endpoints. SKILL.md references a workspace path (~/.openclaw/...), which is an implementation detail but not a data-exfiltration vector.

Install Mechanism

There is no formal install spec; SKILL.md instructs pip install baostock pandas. Installing packages from PyPI is a common, moderate-risk action — expected for a Python tool — but it does mean code is dependent on third-party packages fetched at install time. No obscure download URLs or archive extraction are used.

Credentials

The skill requests no environment variables, no credentials, and no config paths. The Baostock client is used without requiring secrets, which is consistent with the stated purpose.

Persistence & Privilege

The skill is instruction-only with a local script and does not request persistent or elevated platform privileges (always:false). It does not modify other skills or system-wide settings.

Assessment

This skill appears to do exactly what it says: fetch data from Baostock and compute SAR-based analytics. Before installing, consider: (1) pip will install baostock and pandas from PyPI—review those packages if you require strong supply-chain assurance; (2) the script makes network calls to Baostock (so it needs Internet access); (3) the repository/source and homepage are unknown—you should review the included sar_calculator.py yourself (it is present and readable) and run it in a sandbox or isolated environment if you have safety concerns. If you plan to run it regularly, verify Baostock's terms and that no authentication tokens are required for your usage pattern.
