Skill Update

Generate or refine Claude Code skills following Anthropic best practices.

Hard caps (enforced by scripts/skill_linter.py)

• SKILL.md ≤ 150 lines
• reference/*.md ≤ 200 lines (reference/scenarios/*.md ≤ 400 lines)
• README.md ≤ 100 lines
• Every SKILL.md has YAML frontmatter with name + description
• No DO NOT / MUST NOT / NEVER outside an ## Anti-Patterns section
• No challenge-specific identifiers (machine names, lab IDs, lab IPs, preserved flags)
• Every Markdown link resolves to an existing file
• Every reference file is linked from at least one other file (no orphans)
