安全使用建议
Review before installing. The skill appears to be intended as a calculator and has no visible network, credential, persistence, or destructive behavior, but it should be changed to use a strict math parser or AST allowlist before being used on untrusted expressions.
能力评估
Purpose & Capability
The stated calculator purpose matches the files, but scripts/calc.py evaluates user-supplied expressions with Python eval(), which gives the skill capability beyond mathematical calculation.
Instruction Scope
SKILL.md instructs agents to pass expressions to the script but does not disclose raw Python evaluation, warn about untrusted input, or define length and complexity limits.
Install Mechanism
The artifact contains only SKILL.md and a local Python script, with no package install, remote download, or install-time execution shown.
Credentials
For a calculator, exposing local Python expression evaluation is overbroad; harmless testing confirmed the eval path can be abused to invoke shell commands despite disabled builtins.
Persistence & Privilege
No persistence, background worker, credential use, network access, or file mutation is declared, but abused expressions would run with the invoking user's local process privileges.
