refactor(hooks): Replace auto-adapt hook with one-time permissions setup script
Remove the auto-adapt-mode PostToolUse hook (no more dynamic permission learning). Replace with a standalone setup script that seeds ~67 safe auto-mode-equivalent permission rules into settings.json in one shot. Move the script to 09-advanced-features/ alongside the Auto Mode docs.

### Example 7: Auto-Adapt Mode (PostToolUse)
|
||||
### Example 7: Seed Auto-Mode Permissions (One-Time Setup Script)
|
||||
|
||||
Automatically learns from your tool approvals and updates `~/.claude/settings.json` permissions. Every time you accept a tool execution, the hook generalizes the command into a reusable permission rule — so you never have to approve the same type of command twice. Dangerous/destructive commands are **never** remembered.
|
||||
A one-time setup script that seeds `~/.claude/settings.json` with ~67 safe permission rules equivalent to Claude Code's auto-mode baseline — without any hook, without remembering future choices. Run it once; safe to re-run (skips rules already present).
|
||||
|
||||
On first run, it seeds your config with auto-mode-equivalent baseline permissions (read/write files, git operations, package managers, common CLI tools).
|
||||

**Configuration:**

```json
|

{
|
||||
"hooks": {
|
||||
"PostToolUse": [
|
||||
{
|
||||
"matcher": "*",
|

]
|

}
|

]
|
||||
}
|
||||
}
|
||||
```
|
||||
**What gets added:**
|
||||
|
||||
**How it works:**
|
||||
1. `PostToolUse` fires after **every** successful tool execution (meaning you already approved it)
|
||||
2. The hook extracts the tool name and input, then generalizes it into a permission rule
|
||||
3. Compound commands like `git push origin main` become `Bash(git push:*)` — matching any `git push` variant
|
||||
4. The rule is added to `~/.claude/settings.json` → `permissions.allow` if not already present
|
||||
5. On first run, seeds ~70 auto-mode-equivalent baseline permissions
|
||||
| Category | Examples |
|
||||
|----------|---------|
|
||||
| Built-in tools | `Read(*)`, `Edit(*)`, `Write(*)`, `Glob(*)`, `Grep(*)`, `Agent(*)`, `WebSearch(*)` |
|
||||
| Git read | `Bash(git status:*)`, `Bash(git log:*)`, `Bash(git diff:*)` |
|
||||
| Git write (local) | `Bash(git add:*)`, `Bash(git commit:*)`, `Bash(git checkout:*)` |
|
||||
| Package managers | `Bash(npm install:*)`, `Bash(pip install:*)`, `Bash(cargo build:*)` |
|
||||
| Build & test | `Bash(make:*)`, `Bash(pytest:*)`, `Bash(go test:*)` |
|
||||
| Common shell | `Bash(ls:*)`, `Bash(cat:*)`, `Bash(find:*)`, `Bash(cp:*)`, `Bash(mv:*)` |
|
||||
| GitHub CLI | `Bash(gh pr view:*)`, `Bash(gh pr create:*)`, `Bash(gh issue list:*)` |
|
||||
|
||||
**Safety guarantees:**
|
||||
- Dangerous commands (force push, rm -rf, sudo, DROP TABLE, etc.) are **never** remembered
|
||||
- Irreversible operations (npm publish, terraform destroy, prod deploys) are **always** blocked
|
||||
- Commands in the `deny` list are never overridden
|
||||
- The hook never blocks tool execution (always exits 0)
|
||||
- A log file at `~/.claude/auto-adapt-mode.log` tracks all decisions for auditing
|
||||
|
||||
**Generalization examples:**
|
||||
|
||||
| You approve | Rule added | Covers |
|
||||
|-------------|-----------|--------|
|
||||
| `git push origin main` | `Bash(git push:*)` | All git push variants |
|
||||
| `npm run build` | `Bash(npm run:*)` | All npm scripts |
|
||||
| `ls -la src/` | `Bash(ls:*)` | All ls invocations |
|
||||
| `rm -rf /tmp/test` | *(blocked)* | Never remembered |
|
||||
| `git push --force` | *(blocked)* | Never remembered |
|
||||
| `Write` tool | `Write(*)` | All file writes |
|
||||
|
||||
> **Tip:** Delete `~/.claude/.auto-adapt-mode-initialized` to re-seed baseline permissions. Check `~/.claude/auto-adapt-mode.log` to audit what rules were added and which were blocked.
|
||||
**What is intentionally excluded** (never added by this script):
|
||||
- `rm -rf`, `sudo`, force push, `git reset --hard`
|
||||
- `DROP TABLE`, `kubectl delete`, `terraform destroy`
|
||||
- `npm publish`, `curl | bash`, production deploys

### Seeding Auto-Mode-Equivalent Permissions (No Team Plan Required)
|
||||
|
||||
If you don't have a Team plan or want a simpler approach without the background classifier, you can seed your `~/.claude/settings.json` with ~67 safe permission rules that cover the same ground as auto mode's default allow-list.

||||
|
||||
**File:** `09-advanced-features/setup-auto-mode-permissions.py`
|

|

```bash
|
||||
# Preview what would be added (no changes written)
|
||||
python3 09-advanced-features/setup-auto-mode-permissions.py --dry-run
|
||||
|
||||
# Apply once — safe to re-run (skips rules already present)
|
||||
python3 09-advanced-features/setup-auto-mode-permissions.py
|
||||
```
|
||||
|
||||
The script adds rules across these categories:
|
||||
|
||||
| Category | Examples |
|
||||
|----------|---------|
|
||||
| Built-in tools | `Read(*)`, `Edit(*)`, `Write(*)`, `Glob(*)`, `Grep(*)`, `Agent(*)`, `WebSearch(*)` |
|
||||
| Git (read) | `Bash(git status:*)`, `Bash(git log:*)`, `Bash(git diff:*)` |
|
||||
| Git (local write) | `Bash(git add:*)`, `Bash(git commit:*)`, `Bash(git checkout:*)` |
|
||||
| Package managers | `Bash(npm install:*)`, `Bash(pip install:*)`, `Bash(cargo build:*)` |
|
||||
| Build & test | `Bash(make:*)`, `Bash(pytest:*)`, `Bash(go test:*)` |
|
||||
| Common shell | `Bash(ls:*)`, `Bash(cat:*)`, `Bash(find:*)`, `Bash(cp:*)`, `Bash(mv:*)` |
|
||||
| GitHub CLI | `Bash(gh pr view:*)`, `Bash(gh pr create:*)`, `Bash(gh issue list:*)` |
|
||||
|
||||
Dangerous operations (`rm -rf`, `sudo`, force push, `DROP TABLE`, `terraform destroy`, etc.) are intentionally excluded. The script is idempotent — running it twice won't duplicate rules.
