Sample data, for illustration

Not just what it cost, where it went

Open any session and see which step ran long, where the agent stalled or looped, and what each part actually cost.

Cost per task, not per month

Every session rolls up into a real figure, broken down by model, cache tier and tool calls.

Tied to your issue tracker

Attribute sessions to an issue in your tracker, using the CLI you already have signed in. Read-only, no setup.

Drill into any session

Step-by-step view of where a session actually spent its time and your money.

What the numbers are actually for

A per-session cost figure on its own is just trivia. Attributed to a work item and compared across sessions, it starts answering real questions.

Which task quietly cost 10x the others

Per-task rollups surface the outlier ticket, instead of one blended monthly number that hides it.

Where a session stalled or looped

The step-by-step view shows a tool call repeated or a turn that ran long before you even open the transcript.

How agents or models actually compare

Same kind of task, tracked the same way, whether it ran in Claude Code, Codex, or Copilot — so a comparison means something.

What never got claimed

Sessions that ran without a work item attached stay visible as unclaimed, instead of disappearing into a blended total.
