agentop: Skill for Claude Code

AgentOp Project Conventions

Core domain model, attention system, and architectural patterns specific to AgentOp.

When to Use This Skill

• Implementing features touching the core domain
• Working with task hierarchies
• Handling agent sessions and steps
• Implementing the attention system
• Building decision point flows
• Adding new entity types

Core Data Model

Entity Relationships

Task (tree hierarchy via parentId)
  └── Outcome (many per task, represents expected results)
        └── AgentSession (many per outcome, AI execution attempts)
              └── AgentStep (stream of: thinking | action | decision_point)
                    └── DecisionPoint (user approval for sensitive actions)
