Kenning — AI skill for Claude Code

Kenning

**Understand the code your AI writes, while it writes it.**

Coding agents like Claude Code, Codex, Cursor and Copilot now write most of the code, often faster than anyone can read it. You end up waiting while the agent works, then approving changes you never really read. Kenning turns that waiting time into a quick, focused review.

While your agent works, every change it makes becomes a short card in the Kenning panel:

• What changed, in plain English. One line, plus the likely reason for the change.
• What looks risky. Removed tests or checks, deleted error handling, silenced type errors, secrets, new dependencies, shell calls, SQL built from strings, and more. All checks run locally.
• One quick question. A 15-second check on what the change actually does. It's not trivia.
• Flag it, and the agent fixes it. Write what's wrong and Kenning hands it straight to your agent (Claude Code, Codex or Cursor), which addresses it before it finishes. If the agent is idle, it arrives with your next message.

Code on the cards is syntax-highlighted in your theme's colours. In an edited line, only the part that changed lights up, so `1.2 → 1.25` stands out at a glance.

Need more room than the sidebar? Click **⤢** on a card (or press `E`) to open the **full review** in an editor tab:

• Every changed file in a list on the left, riskiest changes first.
• Side by side or unified diffs at full width (V).
• The whole file around a change, with the change marked (W).
• History: your understanding score and reviews over the last 30 days (H).
• Copy review summary: a Markdown summary of what you reviewed and flagged, ready to paste into a pull request.

Your **understanding score** and daily streak show how much of today's AI code you actually understood. The *lines waiting* counter shows what you haven't looked at yet. **Share today** saves an image of your score, ready to post.
