- Rename skill/ to skills/ for consistency with naming conventions
- Rename agent/ to agents/ and command/ to commands/
- Update AGENTS.md with all directory references
- Update scripts/test-skill.sh paths
- Update prompts/athena.txt documentation
This aligns with best practices of using plural directory names and updates
all documentation to reflect the new structure.
Create README.md and enhance AGENTS.md to position this as an
extensible framework for any Opencode skills and agents, not just
PARA/task management. Includes installation, development workflow,
code style guidelines, and Nix flake integration patterns.
