jev-blindspot

jsk4581

827

CLI & Pipelines MIT E2 · source reviewed

A side panel for Claude Code and Codex CLI that shows the blind spots of each prompt you submit: what the request would have needed to consider and shows no sign of. Jev decides, in one call per prompt, whether the prompt is worth a second look; only then does the agent's own headless mode read the project and return the items. Nothing blocks the prompt, nothing is added to the session.

JEV · Decision point

One gate call evaluates worth_checking, risk and possible gaps; local thresholds and duplicate suppression decide whether to start headless analysis.

Keeps the quick prompt gate separate from the deeper repository-reading agent and exposes why the panel remained quiet.
