Applies NIST/CWE security hardening to Python and Rust code. Use when auditing code for vulnerabilities or proposing concrete security remediations.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Harden Codebase Skill Active security hardening: scan the existing repository for vulnerabilities and forward-facing threats, then propose concrete remediations the user can approve, defer, or file. This skill is the engine behind `/harden`. It complements the Claude Code built-in `/security-review` (which scans the pending diff) by sweeping the whole repository against citation-backed checks rather than line-level review of in-flight code. ## When To Use - Quarterly security-posture audits. - Before tagging a release that touches sensitive code paths. - After a published advisory affects the language ecosystem. - When onboarding a new repository and want a baseline. - After integrating a new dependency or upstream service. ## When NOT To Use - Pending-diff review on a single PR. Use `/security-review`. - Architecture-level threat modeling. Use `attune:war-room` with a security-focused panel. - Cryptographic protocol review. The skill flags suspect crypto but does not propose protocol fixes (specialist work). - One-off bug hunting. Use `pensive:bug-review`. ## Required TodoWrite Items 1. `harden:discovery`: inventory languages, build files, hooks, CI workflows …

How to install
mdr add athola/claude-night-market/harden@sha256:6e0baa8b54ea6723The line at the top of this page pins the label git:20260921.ad5ceb4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
