Spend per sub-agent type: runs, the model it mostly used, average cost per run, the share of runs whose tool calls were all read-only, errored tool results, and runs where the requested model differed from the one actually used.

Every point where a sub-agent's model changed, with the real runs before and after compared and a verdict: keep, watch, revert, or too early. These are measured figures, not estimates.

One finding in full, addressed by its stable id from report: what happened, why it costs, what to change, what to expect, plus the evidence table and the patch if there is a file to change.

The price table every figure is computed from, in US dollars per million tokens, with the date it was last verified. Includes any overrides from the user's config.

Rescan the transcript directories now instead of waiting for the automatic rescan, and report how many files were scanned, newly recorded, unchanged, or skipped. Only tallybook's own database is written.

What the coding agents on this machine cost over a window: the total, the split by tool and by model, and the list of findings about what would have been cheaper. Call finding with an id from the list for the full advice.

One session turn by turn: model, effort, token counts and cost per model response. Accepts a full session id or a unique prefix. Never returns prompt text, tool output, or command lines; the database does not hold them.

Sessions in the window with what each cost, sorted by cost or by time, most expensive or most recent first. Includes sub-agent runs as their own rows.
