**Good results start with good requests.**

jev-blindspot is a side panel for [Claude Code](https://claude.com/claude-code) and [Codex CLI](https://github.com/openai/codex). Each time you submit a prompt, the panel shows the prompt's blind spots: what the request would have needed to consider, and shows no sign of considering. It runs next to the session in a browser tab. It does not block the prompt, does not edit it, and does not add anything to the agent's context.

Quick start

Node 20 or newer, a [TypeSafe](https://typesafe.ai) API key, and Claude Code or Codex CLI already logged in.

npm install -g jev-blindspot
mkdir -p ~/.config/jev-blindspot
echo 'TYPESAFE_API_KEY=your-key' > ~/.config/jev-blindspot/env && chmod 600 ~/.config/jev-blindspot/env
jev-blindspot install-hook      # hooks into every agent it finds

For Codex, also trust the new hook once: `jev-blindspot install-hook codex --trust`, or `/hooks` inside Codex. Details in [Install](#install).

Then type `/blindspot` in Claude Code, or `/prompts:blindspot` in Codex. The panel URL comes back in the session at once, with no model turn spent. Open it in a browser tab next to the session and keep working as usual.

From then on, every prompt you submit becomes a card in the panel: quiet when there is nothing to consider, otherwise the blind spots of that request, each with a sentence you can paste into the next prompt. The card also shows what the check cost: the model, the time, the tokens in and out, and for Claude the dollar amount and the number of
