What it does
Blog Audit is an agent skill from Infrasity-Labs/dev-gtm-claude-skills. Full-site blog health assessment scanning all blog files for quality scores, orphan pages, topic cannibalization, stale content, and AI citation readiness. Spawns parallel subagents for comprehensive analysis. Produces per-post scores and a prioritized action queue. Use when user says "audit blog", "blog audit", "site audit", "blog health", "audit all posts", "check all blogs".
Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Marketing & SEO, covering AI search optimization, SEO audit and Subagents. The repository describes itself as: Open-source Claude skills for GEO, AI discoverability, and developer GTM workflows. Built for developer-focused companies that want their documentation to be found, parsed, and… The licence is MIT.
When your agent uses it
- User says audit blog
- Audit all posts
- Check all blogs
Example prompts
- “audit blog”
- “blog audit”
- “site audit”
- “/blog-audit”
Workflow steps
7 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 02cfefb. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Blog Audit loads about 1.8k tokens when it runs. Until then it costs about 98 tokens; SKILL.md has 696 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Blog Audit: Full-Site Health Assessment
Performs a comprehensive blog health assessment across all posts in the project. Scans for quality scores, orphan pages, topic cannibalization, stale content, and AI citation readiness. Uses parallel subagents for efficient analysis and produces a prioritized action queue.
Audit Process
Step 1: Discover Blog Files
Scan the project for all blog content files:
- Glob for
*.md,*.mdx,*.htmlin common blog directories - Common paths to check:
content/posts/blog/src/content/_posts/pages/blog/articles/src/pages/blog/
- Filter out non-blog files: README, CHANGELOG, LICENSE, config files, SKILL.md, package.json, node_modules
- Report: "Found N blog files in [directories]"
If no blog files are found in standard locations, search the entire project root for markdown files with blog-like frontmatter (title, date, description).
Step 2: Parallel Analysis
Spawn subagents via the Task tool for parallel processing across all discovered blog files:
Content Quality Agent
- Score each post on the 30-point content quality scale
- Check paragraph length (target 40-80 words, hard limit 150)
- Check sentence length (target 15-20 words)
- Evaluate heading structure and question-format headings
- Assess readability (Flesch Reading Ease 60-70 target)
SEO Optimization Agent
- Check on-page SEO elements per post:
- Title tag length (50-60 chars)
- Meta description (150-160 chars, includes statistic)
- H1 presence and uniqueness
- Image alt text coverage
- Internal and external link counts
- URL slug quality
Schema Validation Agent
- Detect structured data across all posts
- Validate BlogPosting schema completeness
- Check FAQ schema presence and format
- Verify dateModified matches lastUpdated frontmatter
- Flag missing or malformed schema
Link Health Agent
- Map internal links across all posts
- Build a directed link graph
- Detect orphan pages (zero inbound internal links)
- Detect dead-end pages (zero outbound internal links)
- Check for broken internal link targets
- Recommend bidirectional link opportunities
Freshness Check Agent
- Read lastUpdated or dateModified from each post's frontmatter
- Calculate days since last update
- Flag posts not updated in 90+ days
- Categorize by refresh priority
AI Readiness Agent
- Score each post for AI citation readiness
- Check passage-level citability (120-180 word sections)
- Evaluate Q&A formatting and entity clarity
- Check for TL;DR boxes and citation capsules
- Assess AI crawler accessibility
Step 3: Topic Cannibalization Detection
Analyze across all posts for keyword competition:
- Extract primary keyword/topic from each post:
- Title text
- H1 heading
- Meta description
- First paragraph
- Normalize keywords (lowercase, remove stop words)
- Detect multiple posts targeting the same primary keyword
- Flag competing posts with one of these recommendations:
- Merge: Combine two weak posts into one strong post
- Redirect: 301 redirect the weaker post to the stronger one
- Differentiate: Adjust focus so posts target distinct intents

Step 4: Orphan Page Detection
Build and analyze the internal link graph:
- For each blog post, extract all internal links (relative and absolute)
- Build an adjacency map:
{ page -> [pages it links to] } - Build a reverse map:
{ page -> [pages linking to it] } - Identify orphan pages: posts with zero inbound internal links
- Identify dead-end pages: posts with zero outbound internal links
- For each orphan, recommend 2-3 existing posts that should link to it based on topic relevance
Step 5: Stale Content Detection
Audit content freshness across all posts:
- Read frontmatter fields:
lastUpdated,dateModified,date,updated - Calculate days since last update for each post
- Categorize by refresh priority:
- High (>180 days): Likely outdated, statistics may be stale
- Medium (90-180 days): Review for accuracy, update statistics
- Low (<90 days): Recently updated, no immediate action
- Estimate refresh effort per post:
- Light refresh: Update statistics, check links (1-2 hours)
- Moderate refresh: Rewrite sections, add new data (3-4 hours)
- Heavy refresh: Full rewrite recommended (5+ hours)
Step 6: Generate Site-Wide Report
Aggregate all results into a comprehensive report:
