io.github.TheDecipherist/claude-code-mastery-project-starter-kit/docker

Production Docker best practices for writing Dockerfiles, Compose files, and Swarm stacks. Use whenever creating or editing a Dockerfile, a docker-compose / compose.yaml, or a stack file, or building and optimizing an image. Fixes the handful of things Claude reliably gets wrong: multi-stage builds, layer-cache ordering, exec-form ENTRYPOINT for correct signals and exit codes, init:true, keeping secrets and env out of the image, non-root users, and healthchecks. From production, not defaults.

Use when semantic refactoring is needed in Rider-supported solutions and projects, including .NET/C#, F#, VB, C++, Unity, Unreal Engine, XAML, Razor, and other GameDev or mixed-language projects. Trigger when edits must update declarations and usages across IDE-resolved references — rename symbols, move types or namespaces, safe-delete unused code, extract interface/base class/method, change signatures, or reorganize namespaces. Do not use for file-only moves, config keys, strings, comments, prose-only edits, generated output, or logic changes with unchanged names/signatures.

io.github.mukul975/Anthropic-Cybersecurity-Skills/deploying-decoy-files-for-ransomware-detection

Deploys canary files (honeytokens) across file systems to detect ransomware encryption activity in real time. Uses strategically placed decoy documents monitored via file integrity monitoring or OS-level watchdogs to trigger alerts when ransomware modifies or encrypts them.

Places strategically named decoy files that mimic high-value targets (financial records, credentials, database exports) in locations ransomware typically enumerates first. Monitors for any read, modify, rename, or delete operations on canary files and triggers immediate alerts via email, Slack webhook, or syslog when interaction is detected, providing early warning before full encryption begins.
