optional add-on·runs on your own agent·no account

Find out what slowed your agents down. And what to change.

Agent Deck Insights is an optional paid add-on. Your own Claude Code or Codex reads what Agent Deck recorded and tells you what to change next time: fewer failed calls, less waiting, fewer wasted tokens.

~/what-is-it

Agent Deck shows what happened. Insights explains it.

Insights doesn't run any AI of its own. It hands the numbers Agent Deck already recorded to the Claude Code or Codex you already use, and shows you what comes back.

~/what-it-finds

The habits that slow your agents down.

re-read loopThe same file read again and again, with nothing changed in between.
churn chainEdit, fail, edit again on the same file, and the failed calls in between.
context churnA huge tool result or a cold cache that suddenly makes every turn expensive.
compactionThe conversation was summarised to free up context, so earlier detail was summarised away.
silent subagentSubagents that did nothing, or whose results were never used.
stallCommands that block your agent for minutes, and waits nobody noticed.

~/faq

What exactly do I get for paying?

Reports. Each one is a short list of findings about your last 7 days of sessions: one action, the cause, and the numbers behind it. You can export any report, or open a follow-up session in your agent to ask about it.

Does Agent Deck need Insights?

No. Agent Deck is free and complete on its own. Insights only adds the reports.

Do I need Agent Deck?

Yes. Insights builds on the numbers Agent Deck records. Agent Deck is free, and it installs automatically with Insights.

Which agents does it work with?

Claude Code or Codex, installed on your machine and signed in to your account.

Which editors does it work with?

VS Code 1.126 or later, Cursor, Devin (Windsurf) and Kiro. Agent Deck installs along with it. In Cursor, Devin (Windsurf) and Kiro, install from Open VSX: https://open-vsx.org/extension/nvitlam/agent-deck-insights

What does a report cost me?

Your plan, plus a little usage on your own agent account each time you run a report.

Is my code or chat history sent anywhere?

No. Only numbers, file names and agent names go to your own agent, and you see them before you click Send.

How do I cancel a subscription?

Through Polar, where you paid.
