ctfd skillA

ctfd is agent-read markdown (skill) from lu1sdv/skillsmd: Use when developing, debugging, deploying, or maintaining any CTFd instance or fork - Docker stack issues, plugin development, CSRF 302 errors, theme customization, database migrations, nginx proxy misconfig, SQLAlchemy 1.4 gotchas, pytest test infrastructure, or API 500 responses.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add lu1sdv/skillsmd/ctfd@git:20260314.993db98
Exact content
mdr add lu1sdv/skillsmd/ctfd@sha256:fdbba780d882c1d9

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
