About breaking-changes

breaking-changes is a skill for maintainers of Claude Code plugins. It compares documented API changes with plugin usage and reports affected locations by severity.

Key features

01Diffs Claude Code API against a reference surface
02Checks plugins for changed APIs
03Maps impacts to file and line
04Classifies changes by severity

Use cases

01Check plugin compatibility after Claude Code updates
02Locate code affected by a removed or changed API

Install

Copy the command and run it in a terminal.

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

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
