# Toolkit update

The toolkit ships in two layers, and they update through different mechanisms.
Getting this wrong is the most common source of confusion, so establish which
layer the user means before doing anything.

| Layer | What it holds | How it updates |
| --- | --- | --- |
| **Plugins** (`skills/fk-*`) | skills, agents | Claude Code's own plugin updater |
| **Bootstrap** (`~/.claude`) | hooks, installer, provider scripts, global instructions, the plugins' source of truth | `fkt` |

## 1. Establish the current state

```bash
~/.claude/bin/fkt status
```

This is offline and instant. It prints the installed version, the channel, the
cached check result, whether the worktree is clean, and any security advisories
that apply to the installed version.

## 2. Check for an update

```bash
~/.claude/bin/fkt check
```

Exit codes matter here — read them, do not parse the prose:

| Exit | Meaning |
| --- | --- |
| `0` | up to date, or an available update is snoozed |
| `10` | an update is available |
| `30` | offline, or the remote was unreachable |
| `40` | `~/.claude` is not a git checkout — it must be reinstalled, not updated |

Results are cached for 12 hours. Pass `--force` only when the user explicitly
wants a fresh network check; otherwise the cache is the right answer.

## 3. Apply it

```bash
~/.claude/bin/fkt update
```

Fast-forward only. It **refuses** (exit `20`) rather than destroying work when:

- tracked files are modified — report `git -C ~/.claude status` to the user and
  stop; do not stash or discard on their behalf;
- the checkout carries local commits that are not on the target — show
  `git -C ~/.claude log --oneline <target>..HEAD` and stop.

In both cases the fix is the user's decision. Never pass `--force` to git, never
`reset --hard`, never `clean`.

Add `-y` only when the user has already said to go ahead. `--dry-run` shows the
commits an update would bring in without touching anything.

After a successful update the toolkit runs any pending migrations, then asks for
a Claude Code restart. Tell the user that, and mention that the plugin half
updates separately:

```
/plugin marketplace update fk-toolkit
```

## 4. Channels

```bash
~/.claude/bin/fkt channel          # show
~/.claude/bin/fkt channel stable   # latest v* release tag (default)
~/.claude/bin/fkt channel edge     # origin/main
```

`stable` only moves to validated, tagged releases. `edge` tracks the development
branch and will occasionally be broken. Switching clears the update cache.

## 5. Turning it down or off

```bash
~/.claude/bin/fkt snooze 168   # hide this update for a week
~/.claude/bin/fkt disable      # stop update checks entirely
~/.claude/bin/fkt enable       # turn them back on
```

A newer release always breaks through a snooze. `disable` stops update checks
but **not** security advisories — that is deliberate. Turn those off separately,
and only if the user asks:

```bash
~/.claude/bin/fkt config security_notices false
```

## What this skill must never do

- Run `fkt update -y` without the user having agreed to the update.
- Work around a refusal (exit `20`). The refusal is the feature.
- Edit the user's `settings.json`, `config.json`, or any `*.local.md`.
- Reinstall via `install.sh` to "fix" a failed update — that is a much heavier
  operation with different side effects. Report the failure instead.
