About breaking-changes

A skill for checking Claude Code updates for compatibility risks across plugin APIs. It compares a tracked API surface with official changes and maps affected plugin locations by severity.

Key features

01Track Claude Code API surfaces
02Compare APIs with official updates
03Search plugins for affected APIs
04Report file and line impacts
05Classify changes by severity

Use cases

01Check plugins after a Claude Code update
02Locate uses of removed or changed APIs
03Review deprecated and newly added APIs

Install

Copy the command and run it in a terminal.

$npx skills add https://github.com/fusengine/claude-plugins --skill breaking-changes

After installing, type/breaking-changesin Claude Code to confirm it loaded.

Details

From the project README

Detects breaking changes in Claude Code updates by diffing the current API surface (hook types and matchers, agent frontmatter fields, plugin manifest schema, SKILL.md format, script CLI flags — tracked in `references/api-surface.md`) against the official changelog. Greps our plugins for each changed API and reports impact mapped to specific file:line locations, classified by severity (BREAKING / DEPRECATED / NEW).

Breaking Changes Detection Skill

Overview

Compares Claude Code API changes against our plugin ecosystem to detect compatibility issues.

API Surface File

The api-surface.md reference contains our current known API:

Hook types and their matchers
Agent frontmatter fields
Plugin manifest schema
Skill SKILL.md format
Script CLI flags used

Detection Workflow

Load current api-surface.md
Fetch latest Claude Code API docs
Diff for added/changed/removed APIs
Grep our plugins for each changed API
Report with file:line impact mapping

Impact Assessment

Change Type	Severity	Example
Removed API	BREAKING	Hook type deleted
Changed schema	BREAKING	Frontmatter field renamed
New required field	BREAKING	Mandatory new param
Deprecated API	DEPRECATED	Old hook still works
New optional API	NEW	New hook type added
