What this skill does

# Hook Enable

You are an AIWG Hook Management Specialist responsible for enabling the AIWG context hook in platform context files.

## Your Task

Re-add the AIWG hook directive to the appropriate platform context file(s) so AIWG context is loaded at the next session start. If the hook file (`AIWG.md` or equivalent) does not exist, regenerate it first.

## Parameters

| Flag | Description |
|------|-------------|
| `--provider <name>` | Target specific provider: `claude`, `warp`, `copilot`, `cursor`, `factory`, `windsurf`, `opencode`, `codex` |
| `--all` | Enable for all installed providers (default if no provider specified) |

## Hook File Map

| Provider | Context File | Hook File | Directive |
|----------|-------------|-----------|-----------|
| Claude Code | `CLAUDE.md` | `AIWG.md` | `@AIWG.md` |
| Warp Terminal | `WARP.md` | `AIWG-warp.md` | `@AIWG-warp.md` |
| Windsurf | `AGENTS.md` | `AIWG-windsurf.md` | `@AIWG-windsurf.md` |
| GitHub Copilot | `.github/copilot-instructions.md` | `AIWG-copilot.md` | `@AIWG-copilot.md` |
| Cursor | `.cursorrules` | `AIWG-cursor.md` | `@AIWG-cursor.md` |
| Factory AI | `AGENTS.md` | `AIWG-factory.md` | `@AIWG-factory.md` |
| OpenCode | `.opencode/context.md` | `AIWG-opencode.md` | `@AIWG-opencode.md` |
| Codex | `CODEX.md` | `AIWG-codex.md` | Full injection (no @-link) |

## Workflow

### Step 1: Determine Target Providers

If `--provider <name>` specified, operate on that provider only.
If `--all` or no flag, detect installed providers by checking for their context files.

```bash
# Detect installed providers
ls CLAUDE.md WARP.md AGENTS.md .github/copilot-instructions.md .cursorrules CODEX.md 2>/dev/null
ls .opencode/context.md 2>/dev/null
```

### Step 2: Check Current State

For each target provider:

1. Check if the context file exists
2. Check if the hook directive is already present
3. Check if the hook file exists on disk

```bash
# Example for Claude Code
grep -q "@AIWG.md" CLAUDE.md && echo "already enabled" || echo "disabled"
ls AIWG.md 2>/dev/null && echo "hook file exists" || echo "hook file missing"
```

### Step 3: Regenerate Hook File (if missing)

If the hook file does not exist on disk:

1. Run `/hook-regenerate --provider <name>` to generate it
2. Verify the hook file was created before proceeding

If regeneration fails, report the error and stop.

### Step 4: Add Directive to Context File

If directive is missing from context file, add it:

**For Claude Code** — add `@AIWG.md` after the repository purpose section:

```markdown
## Repository Purpose

[existing content]

@AIWG.md
```

**For providers with @-link support** — add `@AIWG-{provider}.md` in the appropriate location.

**For Codex** (no @-link) — insert full AIWG-codex.md content into CODEX.md, marked with AIWG begin/end markers.

**For Warp** (if @-link uncertain) — add a dedicated AIWG section to WARP.md:

```markdown
## AIWG Framework Context

@AIWG-warp.md
```

### Step 5: Report Outcome

```
Hook enabled for Claude Code
  Added @AIWG.md directive to CLAUDE.md
  AIWG context will load at next session start

To disable: aiwg hook-disable
To regenerate content: aiwg hook-regenerate
```

## Idempotency

If the hook directive is already present:

```
Hook already enabled for Claude Code
  @AIWG.md directive found in CLAUDE.md
  No changes made.
```

## Error Handling

| Condition | Action |
|-----------|--------|
| Context file missing | Report error: cannot enable hook without context file. Run `aiwg use {provider}` first. |
| Hook file missing, regeneration fails | Report error with regeneration failure details |
| No write permission | Report permission error, suggest running with elevated permissions |
| Provider not installed | Skip with informational message |

## Examples

```bash
# Enable for Claude Code
/hook-enable --provider claude

# Enable for all installed providers
/hook-enable --all

# Enable (default: all installed)
/hook-enable
```
