Implement configurable learning storage path with .config/learning marker

[luqs1]

Summary

Add configurable storage path for learning research files instead of hardcoded paths like or .

Behavior

First Run Detection

1. Check if exists
2. If not exists → Agent prompts user: "Where should learning research be stored? [default: ~/.config/learning]"
3. If user enters custom path → Write path to
4. If user leaves default (empty) → Leave file empty but existing

Subsequent Runs

• Read to get storage location
• If file is empty → Use as default
• If file has content → Use that path

File Structure

Implementation

Plugin (learning-agent.js)

• Add install logic to create if missing
• Add function to read/write the marker file

Skills

• : Read to determine storage location
• : Same

Agent Prompts

• Update knowledge base path instructions in both opencode and claude agent files

Why This Approach

• is standard on Linux/macOS, maps to on Windows
• Empty file = use default ()
• Custom path = user specifies (e.g., )
• Both opencode and Claude Code can share the same marker file
• User has full control over storage location
