# The skills tell an agent when to read the proxium project memory and when to
# write to it. They need the proxium MCP server connected in the agent:
# https://proxium.tech/connect
#
# Folders (agentskills.io):
#   ~/.agents/skills  Codex, Gemini CLI, Cursor, GitHub Copilot, VS Code, OpenCode, goose, Amp
#   ~/.claude/skills  Claude Code
# --project writes to ./.agents/skills and ./.claude/skills of the current folder,
# for a repository the whole team shares. --dir PATH writes to PATH only.
#
# It replaces only the folders proxium-memory, proxium-memory-recall and
# proxium-memory-save, and touches nothing else.
