mintlify — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited mintlify (Rules) and scored it 45/100 (orange). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 42 high-severity and 2 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A base64 string of 128+ characters appears in a documentation file. Encoded prompt injection hides the hostile instruction in base64 — invisible to keyword filters — and relies on the agent's ability to decode it at runtime. There is no normal authoring reason to embed a multi-hundred-byte base64 blob in skill docs.

Organize domain-specific knowledge into discoverable, composable skills that keep AI context lean and focused.
The Copilot Skills Architecture is a modular system for organizing specialized knowledge in GitHub repositories. Skills follow a three-part architecture:
.github/copilot-instructions.md enables AI to find skills.github/copilot-instructions.md enables AI to find relevant skillsSee .specify/memory/constitution.md for full details.
.github/copilot-instructions.md/skill-{name} commandUser: "I need to extract form fields from a PDF"
→ Copilot checks keyword routing map
→ Finds "PDF" triggers PDF Handling skill
→ Suggests `/pdf-handling` command
→ Loads .github/prompts/pdf-handling.skill.prompt.md
→ Suggests bundled script in scripts/ directory.github/copilot-skills/templates/.github/prompts/{skill-name}.skill.prompt.md.github/instructions/{skill-name}.instructions.md.github/copilot-skills/{skill-name}/ if needed for scripts/detail files.github/copilot-instructions.md.specify/checklists/skill-compliance-checklist.md)See AUTHORING.md for step-by-step guidance.

YAML frontmatter at the top of SKILL.md containing name, description, version, tags, and dependencies:
---
name: "PDF Handling"
description: "Extract text, fill forms, and manipulate PDF documents"
version: "1.0.0"
tags: ["documents", "pdf", "forms"]
dependencies: ["pypdf2", "pdfplumber"]
---Markdown files in a skill directory (e.g., forms.md, reference.md) providing focused information on specific topics. Each stands independently and can be read without reading others.
Executable scripts (Python, Shell, JavaScript, etc.) in a skill's scripts/ subdirectory. Used for deterministic operations documented in skill prompts.
The keyword routing map in .github/copilot-instructions.md listing all available skills with trigger keywords, enabling AI to discover relevant skills automatically.
Skills use a 3-layer information architecture:
.github/copilot-instructions.md.github/prompts/Benefits:
Skills can reference other skills to enable complex workflows:
Task: "Generate a financial report as a PDF with branded styling"
Workflow:
1. Load Financial Reporting skill
→ Generates report data (templates, calculations)
2. Load PDF Building skill
→ Converts data to PDF format
3. Load Brand Guidelines skill
→ Applies styling and fonts
Result: Composed workflow using 3 coordinated skillsGuidelines:
By implementing the skills architecture, we achieve:
.github/copilot-instructions.mdThe main Copilot instructions contain the skills system:
.specify/templates/Templates for creating new features, specs, and tasks reference the skills architecture:
.specify/checklists/Compliance checklist ensures all skills meet constitutional principles:
