URL validation and content sanitization for untrusted sources — use when handling external input safely.
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
# Security Framing Standard ## Overview This skill defines security patterns for handling untrusted external content. **All octopus workflows that fetch or analyze external content MUST apply these patterns.** ``` ┌─────────────────────────────────────────────────────────────────────────────┐ │ SECURITY FRAMING WORKFLOW │ ├─────────────────────────────────────────────────────────────────────────────┤ │ │ │ Step 1: URL Validation │ │ → Reject dangerous URLs (localhost, private IPs, metadata) │ │ → Validate URL format and protocol │ │ → Apply platform-specific transforms (Twitter → FxTwitter) │ │ ↓ │ │ Step 2: Content Fetching │ │ → Fetch via WebFetch or approved methods only │ │ → Enforce timeout limits │ …

How to install
mdr add nyldn/claude-octopus/skill-security-framing@sha256:f4cd1ec5239995caThe line at the top of this page pins the label git:20260813.14437ae, 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.
