Blog Analyzer: Quality Audit & Scoring

Bundled paths below use host Markdown substitution of ${CLAUDE_SKILL_DIR}; it is not an exported shell variable. Resolve them before execution, quote paths, and refuse nonabsolute overrides. Pass blog_reference_root resolved from ${CLAUDE_SKILL_DIR}/../blog/references, blog_template_root from ${CLAUDE_SKILL_DIR}/../blog/templates, and needed sibling roots to agents. Read the main reference orchestration-details.md before loading project context; pass only its helper-fenced output to downstream agents.

Scores blog posts on a 0-100 scale across 5 categories and provides prioritized improvement recommendations. The score is an internal editorial-readiness heuristic, not a Google ranking factor or calibrated citation probability. Works with local files or published URLs.
