bizyair-video
基于 BizyAir 异步 API 的视频生成助手，支持 5 种视频生成模式
This is a legitimate BizyAir video generation API skill with properly declared network access and API key usage. Minor documentation gap exists between declared shell usage in requires vs actual subprocess execution, but no malicious behavior detected.

Safe to install
Update SKILL.md to explicitly declare shell:WRITE permission for curl-based HTTP requests, and add dependency pinning for jq/bc in script documentation.

Severity Finding Location
Low
Shell execution not explicitly declared in SKILL.md Doc Mismatch
SKILL.md declares 'requires: curl' but scripts execute bash scripts with curl subprocess. The shell:WRITE permission is not explicitly documented.
requires: {"curl": "用于执行 HTTP 请求"}
→ Add explicit permission declaration for bash/shell execution, or restructure scripts to be invoked differently
 SKILL.md:5
Info
Placeholder API key examples in documentation Doc Mismatch
SKILL.md:302 and scripts/README.md:141 contain 'your_actual_api_key_here' placeholder text. These are example strings, not actual credentials, but could cause user confusion.
export BIZYAIR_API_KEY="your_actual_api_key_here"
→ Use clearly marked placeholder format like '<INSERT_API_KEY>' or '{{API_KEY}}' to distinguish from real credentials
 SKILL.md:302
Low
Optional script dependencies not documented as required Supply Chain
get_task_outputs.sh uses 'bc' for floating-point math (line 56), but this is not declared in system requirements
scale=1; $ms / 1000 | bc 2>/dev/null
→ Add 'bc' to required dependencies or use pure bash arithmetic
