安全使用建议
This skill appears to do what it says: it runs a single Wolfram Language expression via WolframKernel and returns exact/numeric/verification results. Before installing or enabling it, ensure your WolframKernel is trusted and run the skill in an isolated environment if you expect untrusted input. Do not enable --allow-unsafe in production or on systems with sensitive data. Be aware the safety check is a regex-based blocker of known dangerous symbols and may not catch every possible Wolfram expression that could perform I/O or network access; if you need stronger guarantees, run the kernel in a sandbox/container or refuse expressions that contain unfamiliar symbols.
功能分析
Type: OpenClaw Skill
Name: math-expression
Version: 1.0.2
The skill is a legitimate utility for evaluating Wolfram Language expressions to solve mathematical problems. It includes a Python script (scripts/eval_expression.py) that implements a safety mechanism using a blacklist of unsafe symbols (e.g., 'Import', 'Run', 'URLRead') to prevent filesystem, network, or process-level access. The instructions in SKILL.md and README.md are clearly aligned with the stated purpose and explicitly guide the agent to maintain safety boundaries, with no evidence of malicious intent, data exfiltration, or prompt injection.
能力评估
Purpose & Capability
Name/description match the declared binaries (WolframKernel) and Python dependency (wolframclient). Requiring WolframKernel is appropriate for evaluating Wolfram Language math expressions. No unrelated binaries, env vars, or config paths are requested.
Instruction Scope
SKILL.md and the script restrict usage to single Wolfram Language math expressions and explicitly block many unsafe symbols (Import, URLRead, Run, Get, etc.). The runtime does execute the expression in a WolframKernel session, which is expected, but this means the kernel could perform side effects if the expression uses symbols not caught by the blocker. The guard is regex-based and may not be exhaustive (edge-case constructs might bypass it). The skill documents the risk and exposes --allow-unsafe only for isolated environments.
Install Mechanism
No install spec (instruction-only plus an included helper script). No downloads or external installers. Dependencies are reasonable and documented (python3, wolframclient, WolframKernel).
Credentials
No environment variables, credentials, or config paths are requested. The lack of secret access is proportionate to the stated functionality.
Persistence & Privilege
The skill does not request always: true and does not attempt to modify other skills or system-wide config. It runs only on explicit invocation or normal autonomous invocation per platform defaults.
