Monitor existing content for ranking drops and trigger refresh workflows. Triggers on: "check for content decay", "which content needs updating", "content refresh", "ranking drops", "traffic decline", "stale content", "content audit", "what to refresh", "outdated content", "content performance check", "update old articles", "declining rankings", "content maintenance", "refresh priority list", "which articles are losing traffic", "SEO content audit".
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
# Content Decay Detector
Monitor existing content for ranking drops and generate a prioritized refresh queue. Refreshing decaying content is the highest-ROI SEO activity — it's faster and cheaper than creating new content, and recovering a lost position is easier than earning a new one.
## Stage
S3: Blog & SEO — Blog maintenance and optimization. This skill keeps your existing content competitive and prevents rankings from silently eroding.
## When to Use
- User has existing blog content and wants to check for decay
- User notices traffic declining on specific pages
- User asks "what content needs updating?"
- User says "content decay", "ranking drops", "stale content", "refresh", "content audit"
- Monthly maintenance check — should run every 30 days on active blogs
- After `seo-audit` reveals declining pages
## Input Schema
```yaml
site_url: string # REQUIRED — the site to audit
# e.g., "myblog.com", "example.com/blog"
content_list: object[] # OPTIONAL — specific pages to check
- url: string # Page URL
title: string # Page title
publish_date: string # Original publish date

How to install
mdr add affitor/affiliate-skills/content-decay-detector@sha256:2abaa1b6f53f772bThe line at the top of this page pins the label v1.0.0, 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.
