JSON Output

Use --json on either public command:

agent-burn summary --json
agent-burn summary --value --json
agent-burn summary --value --cursor-plan ultra --json
agent-burn harness claude --json
agent-burn harness codex --json

Use --jq to filter JSON directly:

agent-burn summary --json --jq '.totals'
agent-burn harness claude --json --jq '.window'
agent-burn harness codex --json --jq '.spendMix'

Harness JSON includes spendMix, a trailing-30-day breakdown of input, output, cache write, and cached input token classes with token percentages and API-equivalent cost percentages.

The JSON shape is intended for dashboards and scripts. Prefer command names summary and harness.
