Manage system prompts for multiple coding agents with agent-purge

This tool uses a local console or CLI to let users override, replace, or append a single system prompt (persona) across multiple coding agents like codex, claude, and grok. It supports hot-swapping and is fully reversible, with all data stored locally on your machine.

Steps

1Install the tool globally by running `npm i -g agent-purge` (requires Node ≥ 20).
2Launch the local console for first-time use by running `agent-purge web`, view or select a persona at http://127.0.0.1:7788, and generate the local data directory `~/.agent-purge/`.
3Manage or switch personas by using `agent-purge ls` to list all personas, and `agent-purge use <id>` to switch the current persona.
4Configure the injection channel or permanent installation by running `agent-purge install <h>` to write configurations to the managed location of a specified harness, or use `agent-purge arm <h>` to enable the injection channel.
5Undo and restore by running `agent-purge uninstall <h>` or `agent-purge disarm <h>` to revert changes byte-for-byte if needed.

Copy-ready prompt

Act as an efficient prompt engineer and help me write a system prompt (persona) for [target Coding Agent, e.g., claude / codex]. The core goal of the prompt is: [enter the specific rules, output format, or role settings you want the AI to strictly follow]. Output the body content directly in Markdown format so that I can place it into the agent-purge personas directory.

Replicating Stripe's internal AI agent workflow

Handle repetitive tasks using the same AI agent setup used internally by Stripe, reducing task completion time from 20 days to 4 days compared to standard Claude Code. This system is built using over 100 saved prompts (one per step) with multiple agents collaborating to handle the build work.

Generate an interactive codebase map with Claude or Codex

Use the Floorplan plugin with Claude Code or Codex to transform your application codebase into a plain-English interactive map. It displays files, modules, and cross-repo network connections, while also running app health checks and tracking recent AI modifications.
