Ideas: additional dependency types beyond skills

[kasperjunge]

Idea

Expand agr to support additional dependency types beyond skill. Two candidates:

1. Instruction files (type = "instructions")

A directory containing either an AGENTS.md or CLAUDE.md file. These provide project-level or agent-level instructions without being executable skills.

dependencies = [
    {handle = "username/repo/instructions", type = "instructions"},
]

2. Ralph loops (type = "ralph")

A directory containing a RALPH.md file following the Ralph loop format from Ralphify. These define structured agent loops.

dependencies = [
    {handle = "username/repo/my-loop", type = "ralph"},
]

Open questions

• Where should each type be synced to? Skills go to skills/ — do instructions go somewhere else?
• Should agr sync handle all types uniformly, or does each type need its own sync logic?
• Validation: what makes a valid instruction dir vs a valid ralph dir?
• How does this affect agrx? Should it support running ralph loops ephemerally?

Why

Supporting more types makes agr a general-purpose agent resource manager rather than just a skill manager. Instruction files and ralph loops are both gaining traction in the ecosystem.
