api-hardening skillC

api-hardening is agent-read markdown (skill) from jamditis/claude-skills-journalism: API hardening for Express, FastAPI, and serverless. Use for rate limiting, CORS, input validation, API keys, or OWASP API Top 10..

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 jamditis/claude-skills-journalism/api-hardening@git:20260818.3e0e3a8
Exact content
mdr add jamditis/claude-skills-journalism/api-hardening@sha256:7287ea0f9344fcbe

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.
