Overview

About This Skill

Changeling is a Claude Code agent skill that reads persona definition files from ~/.claude/@lib/agents/ and assumes those identities to complete tasks. It supports single-persona mode, fusion mode (blending two or more agents simultaneously), and ad-hoc mode where you describe a persona in plain language without needing a file at all. This makes it practical for developers who maintain a library of specialized agents—such as a prompt engineer, code reviewer, or any custom role—and want to invoke the right expertise for a given task without switching tools or sessions. Typical invocations follow the pattern: @agent-changeling become <identity> [fused with <identity_2>] <task>.

How to Use

Place agent definition files in ~/.claude/@lib/agents/. Invoke the skill using @agent-changeling become <identity> <task> for a single persona, add fused with <identity_2> to blend multiple agents, or describe an ad-hoc role in plain language if no file exists.

Use Cases

Switch Claude Code into a prompt-engineer persona to critique or refine agent prompts

Fuse two specialized agents (e.g., code-reviewer and security-auditor) for combined analysis

Invoke an ad-hoc persona described in plain language when no agent file exists

Maintain a local library of agent definitions and load them on demand per task
