Each run now appends a report to the agent's reply: the tool calls it made plus
input/output token totals and the dollar cost. opencode's --format json emits
per-step `tokens` and `cost` (USD, priced from the model) on step_finish events;
build-activity-log.sh sums them across the run.
- build-activity-log.sh: compute for EVERY agent (not just devs — @pm/@qa also
call tools and cost money); output a collapsed <details> report (summary line
shows "N tool calls · in X · out Y · $Z"; body lists the tools + a token/cost
breakdown). Zero-tool runs get a one-line "$Z · in X · out Y" footer.
- publish.sh: build $activity once (near the top) and append it to every agent's
reply — @pm plan/finalize, @qa verdict/recommendations, and dev PR comments.
- agent.yml: rename the step accordingly.
Models without pricing (self-hosted ollama) report cost $0.0000.
