From klingai-pack
Implements Python debug client for Kling AI API with request/response logging, tracing, and timings. For troubleshooting video generation or observability.
npx claudepluginhub jeremylongshore/claude-code-plugins-plus-skills --plugin klingai-packThis skill is limited to using the following tools:
Structured logging, request tracing, and diagnostic tools for Kling AI API integrations. Captures request/response pairs, task lifecycle events, and timing metrics for every call to `https://api.klingai.com/v1`.
Creates isolated Git worktrees for feature branches with prioritized directory selection, gitignore safety checks, auto project setup for Node/Python/Rust/Go, and baseline verification.
Executes implementation plans in current session by dispatching fresh subagents per independent task, with two-stage reviews: spec compliance then code quality.
Dispatches parallel agents to independently tackle 2+ tasks like separate test failures or subsystems without shared state or dependencies.
Structured logging, request tracing, and diagnostic tools for Kling AI API integrations. Captures request/response pairs, task lifecycle events, and timing metrics for every call to https://api.klingai.com/v1.
