Track releases, changelogs, and breaking changes from any software project's web page.
Prerequisites
CF Browser MCP server must be configured in .mcp.json (see quick start).
Why This Skill?
GitHub releases, framework changelogs, and library docs are often JS-rendered pages that WebFetch can't read. This skill uses browser_json to extract structured release data from any page.
Workflow
Step 1: Determine Source
From the user's input, resolve the changelog URL:
- GitHub project →
https://github.com/{owner}/{repo}/releases - npm package →
https://github.com/{owner}/{repo}/releases(resolve via npm registry) - Direct URL → use as-is (e.g.,
https://nextjs.org/blog) - "latest changes to X" → search for the project's releases page
Step 2: Extract Releases
browser_json(url, prompt="Extract the latest N releases with version, date, and key changes as JSON array")
For changelog pages (non-GitHub):
browser_json(url, prompt="Extract version entries with version number, release date, and list of changes")
Step 3: Analyze
For each release:
- Flag breaking changes (look for "BREAKING", "migration", "deprecated")
- Flag security fixes (look for "CVE", "security", "vulnerability")
- Categorize changes: features, fixes, performance, deps
- Note if any changes affect the user's project (if context available)
Step 4: Report
Output a structured summary:
## {Project} — Latest Releases
### v2.1.74 (2026-03-12)
- **NEW**: Added `autoMemoryDirectory` setting
- **FIX**: Fixed memory leak in streaming API response buffers
- Action needed: None
### v2.1.73 (2026-03-11)
- **NEW**: Added `modelOverrides` setting
- **FIX**: Fixed freezes and 100% CPU loops
- Action needed: Update recommended (stability fix)
### v2.1.72 (2026-03-10)
- **NEW**: Tool search bypasses third-party proxy gate
- Action needed: None
Parameters
urlorproject(required): GitHub repo, npm package name, or direct changelog URLcount(optional, default=5): Number of releases to fetchwatch(optional): If set, compare against last known version and highlight new releases
Examples
"What's new in Claude Code?"
→ browser_json("https://github.com/anthropics/claude-code/releases") → structured summary
"Check for breaking changes in Next.js 15"
→ browser_json("https://nextjs.org/blog") → filter breaking changes
"Latest Hono releases"
→ browser_json("https://github.com/honojs/hono/releases") → version + changes
"Has Astro released anything since 5.18?"
→ Extract releases → filter versions > 5.18
