Session Inspector
Every agent session in range in one sortable table, then open one to see where it actually went — a “Where tokens go” split plus the tools it ran, the MCP servers it called and the skills it fired.

Why You Need This
How this feature boosts your daily productivity
“How many sessions ran” is a number; “where did that session's tokens go” is the question you are really asking when a run costs more than it should. The Sessions tab in Analytics filters by title, project, agent or session id and sorts by start, span, tokens, tools, MCP calls or skills. Opening a row splits the token bill into input, output, cache and reasoning, estimates tool-turns against plain text-turns, and lists the tools, MCP servers and skills the session used, with a pill that says how complete the scan was rather than quietly under-reporting. Pick a second row to compare two sessions side by side.
How It Works
Get started in 4 simple steps
Open Analytics → Sessions
Press ⌘⇧A, then the Sessions tab. Every session in the current range lands in one table.
Narrow it
Filter by title, project, agent or session id, then sort by start, span, tokens, tools, MCP calls or skills.
Open one session
A “Where tokens go” split (input, output, cache and reasoning) plus the tools it ran, the MCP servers it called and the skills it fired, with an estimate of tool-turns against plain text-turns.
Check coverage, then compare

Prompt History
Search prompts and sticky notes from Remote Control while away from the desktop. Switch between This project and All projects, filter prompts by agent or notes by source, copy entries, delete with Operator access, and sync local prompt history.
Resume UI
Read any past AI session before you resume it. Resume AI Sessions is a split view with a searchable list of every Claude Code, Codex, Gemini CLI and other agent session on the left and a live preview of the project, branch, tool calls and conversation on the right, with replies rendered as Markdown, with Resume, bypass permissions and an editable command one click away.
Combine Sessions
Merge several past AI sessions into one opening prompt, or hand a single session to a different agent. Tick sessions in Resume AI Sessions, see a token estimate of the context they add, and send the result to a new chat with any agent or preset or to a terminal that is already open.
AI Diff Review Panel
Track every file modification any AI agent makes — Claude Code, Codex, Gemini, Amp, custom — and review, accept, or revert their work per file from a dedicated panel with inline diff overlays in the editor.
