🤖 Claude Code hooks that use [Jev](https://docs.typesafe.ai) to make cheap,
calibrated judgement calls **inside the agent loop** — where a full LLM call would
be too slow and too expensive to sit in the hot path.

> 👉 **New here?** [**WHY.md**](WHY.md) is the two-minute version: what breaks
> without this, what Jev is doing that's interesting, and what a year of it cost
> (\$0.14).

### 🎯 Six hooks so far

| | Hook | Event | What it does | Default |
| :-: | --- | --- | --- | --- |
| 🛡️ | **danger gate** | `PreToolUse` | Blocks destructive tool calls before they run | 🔴 **enforcing** |
| 🔔 | **failure notice** | `PostToolUse` | Tells the agent when command output contains a failure | 🔴 **enforcing** |
| ✅ | **completion check** | `Stop` | Judges whether Claude actually finished its turn | 🟡 **log-only** |
| 🔍 | **scope check** | `PreToolUse` | Notes when a write isn't part of what you asked for
