Build a Claude Code behavior control plugin with clean configuration UI
The Problem
Developers using Claude Code are frustrated because it ignores custom instructions, limiting control over agent behavior in coding workflows. Alternatives like Cline (58K stars) and Continue.dev (30K stars) show high demand for agentic tools, with thousands of GitHub stars indicating a large user base of indie hackers and solo founders seeking better CLI/IDE integrations. Users currently spend $10-20/mo on tools like Copilot, Cursor, and Claude Pro, but lack targeted solutions for Claude-specific behavior control.

Simple plugin to get Claude Code to listen to you
Core Insight
Provides a clean configuration UI to enforce custom instructions and behavior control for Claude Code, filling gaps in Superpowers' structured skills, Continue.dev's model flexibility, and Cline's manual setup by offering precise, UI-driven overrides missing in current plugins.
- Target Customer
- Indie hackers and solo founders building AI coding agents (e.g., using Claude Code), part of the 39K+ Aider stars and 58K+ Cline stars developer community, within the growing devtools market for agentic coding.
- Revenue Model
- SaaS freemium: Free tier (BYO API key, basic config) / $15-20/mo Pro (hosted UI, advanced controls, unlimited sessions), aligned with competitor pricing like Cursor ($20/mo) and Claude Pro ($20/mo).
Competitive Landscape
Not specified on site; part of Claude plugin ecosystem, typically free or BYO API key
Superpowers focuses on lifecycle management and skills for brainstorming, TDD, debugging, but lacks a clean configuration UI for custom instructions and behavior control. Developers report frustration with overriding Claude's default behaviors in such structured frameworks.
Free[6]
Continue.dev offers model flexibility and self-hosting as an IDE extension, but does not specifically address Claude Code's ignorance of custom instructions or provide a dedicated UI for behavior control in agent workflows.
Free (BYO key)[6]
Cline provides VS Code-native agentic coding with plan-review-run loops and model choice, but users note it requires manual configuration without a streamlined UI for precise Claude behavior overrides like custom instructions.
Not specified; typically free plugin
Claude-Mem adds long-term memory for context across sessions, but fails to control core agent behaviors or custom instructions, leaving developers without fine-grained control over Claude Code's execution style.
Free / $20/mo[6]
Cursor excels in AI IDE autocomplete and daily coding with multi-model support, but does not integrate deeply with Claude Code for behavior plugins or offer configuration UIs to enforce custom instructions.
