This skill should be used while WRITING any backend, API, auth, or data-handling code for a web app or SaaS — to prevent vulnerabilities before they ship, not to audit them after. Trigger phrases include "add an endpoint", "handle user input", "store user data", "is this secure", "build the API", "save to the database", "handle the form", "user uploads", "process payment", "handle secrets", "set up CORS", "rate limit". It applies OWASP Top 10 prevention, input validation, secrets hygiene, and…
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
# Secure Coding This skill keeps you from introducing vulnerabilities while you build. It is **prevention, not audit** — it runs at the moment you write an endpoint, a form handler, or a database write, and bakes in the safe default before the bug exists. Analogy: it is the seatbelt you put on before driving, not the crash investigator who shows up afterward. Audit tools (Trail of Bits, Semgrep, CodeQL) inspect the wreck. This skill stops the crash. ## Scope This skill is for the solo dev or small team who has **no security tooling installed** and just wants to ship without leaving holes. If a dedicated audit plugin is present, this skill still runs first — preventing a vuln is always cheaper than finding it later. ## Trigger Activate whenever code touches: a request handler/endpoint, user input, a database write, authentication, file uploads, secrets/env vars, CORS, or any third-party webhook. Default-deny mindset: code with no explicit security decision is the bug. ## Discovery (max 3 questions, only if unknown) 1. Is this endpoint/data public, authenticated, or admin-only? 2. Does it touch personal data (email, name, payment, location, anything identifying a person)? …

How to install
mdr add martinolivero/saas-builder/secure-coding@sha256:6ae881f46b6e6d25The line at the top of this page pins the label git:20261007.f2beefe, 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.
