OSOP Session Logger

You just completed a task. Now produce a structured session log.

What to create

1. sessions/YYYY-MM-DD-<short-desc>.osop — workflow definition
2. sessions/YYYY-MM-DD-<short-desc>.osoplog.yaml — execution record

Create the sessions/ directory if it doesn't exist.

Node type mapping

Sub-agent tracking

If you spawned sub-agents, use parent on child nodes and spawn edge:

nodes:
  - id: "coordinator"
    type: "agent"
    subtype: "coordinator"
  - id: "explore_1"
    type: "agent"
    subtype: "explore"
    parent: "coordinator"
edges:
  - from: "coordinator"
    to: "explore_1"
    mode: "spawn"

Important

• Be accurate about what tools were used and how many calls
• Include reasoning for non-obvious decisions
• Estimate durations based on tool call timing
• If the task failed, set status to FAILED and include error details
