secure-coding SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
secure-coding from slilbudget/knowledge-delta-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add slilbudget/knowledge-delta-skills/secure-coding@git:20260929.c1f17bdPins git:20260929.c1f17bd in mdr.lock. Pin the fingerprint instead.

Use when writing JavaScript, Node.js, HTML, CSS code for websites, landing pages, admin panels, APIs. Reduces common vulnerability classes (XSS, injection, SSRF, etc.) via secure libraries, proper headers, and safe patterns. Includes AI code vulnerability patterns.
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 (JS / Node.js / HTML / CSS) Apply automatically when writing any web code — hardened by default. Validate deployment topology (reverse proxy, TLS termination, CDN) before applying `trust proxy`, HSTS `preload`, or cross-origin isolation defaults. AI-generated code has 2.74x more vulnerabilities than human-written; 45% of AI samples introduce an OWASP Top 10 vuln (Veracode, 100+ LLMs). ## Workflow **New code:** secure defaults first (helmet, cors explicit origins, rate-limit, body size limit) → per endpoint: auth middleware → zod validation → parameterized queries → generic errors → scan against "Never Do" table. **Dependencies (prefer `context7` MCP; else npm registry / GitHub / GHSA):** latest stable version, no open critical/high CVEs, maintainer disqualify only on: deprecated, archived, unanswered CVE > 90 days, ownership transferred to unknown party (mature libs like `argon2`/`helmet`/`jose` sit quiet for months and stay canonical). Apps: `package-lock.json` + `npm ci`; libs: semver ranges + audit in CI. Prefer Safe Library Stack below. …

How to install
mdr add slilbudget/knowledge-delta-skills/secure-coding@sha256:4d8d7a668f779fb9The line at the top of this page pins the label git:20260929.c1f17bd, 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.
