From the source SKILL.md

A change spec is a lightweight requirement spec for a brownfield small change. It captures the delta only — current vs desired behavior — and points at the impacted code from codebase-context.md. It is NOT a from-scratch req-spec.

What this skill does

Write Change Spec is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/write-change-spec/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Write Change Spec Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 196,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
