FreeLLMagent-purge lets users swap system prompts across multiple coding agents via a local web console
The open‑source tool offers replace, append, strict and off modes to manage personas for agents like Codex, Claude and Pi.
ZiChuanLan released agent-purge, a Node‑based CLI and web console that centralises system prompt management for a range of coding agents.
The tool supports four modes—replace, strict, append and off—and can hot‑swap personas without touching disk files.
Installation works via npm (Node ≥ 20) or npx, and the web console runs at http://127.0.0.1:7788, displaying available personas stored in ~/.agent-purge/personas/.
Agent‑purge integrates with magpie gateway plugins, allowing prompt changes for agents that route requests through the gateway without restarting each harness.
Supported agents include Codex, Claude, Grok, OMP, Hermes, Zcode, Opencode, Pi and others, each with documented injection points and version numbers.
Ce que cela signifie pour vous
Developers can experiment with different system prompts across many AI coding assistants from a single interface, simplifying prompt engineering and testing. The zero‑dependency, reversible design also supports users who prefer fully local, open‑source tooling over cloud‑based prompt management.
