Observe

Observe phase

Observe means you can see tokens, cost, and traces for a run — not only the final printed reply.

The Observe course adds Langfuse and weekly usage rolls. Start with a named session on the CLI.

Example

praisonai run "Summarise agents in one line" --session lifecycle-demo
praisonai session list

Example explained

• –session — Groups runs so totals accumulate.
• session list — Shows token and cost columns when available.
