3535| `next.origin` | `{ plugin, tier }` of whoever fired the event. Claude Code itself is `{ plugin: 'engine', tier: 'core' }`. A mod's `tier` is its priority group in the [order mods run in](/docs/en/plugins/mods/events#the-order-mods-run-in): `prepend`, `user`, `append`, or `builtin`. |
3636| `next.budget` | The hook's time limit in milliseconds: `next.budget.ms` is the whole limit, and `next.budget.remainingMs` is what's left now |
3737| `next.to(e, tier)` | Skips to a later tier, which is `append`, `builtin`, or `core`. `next.to(e, 'append')` skips the mods a user installed. Only a mod in `prependPlugins` or `appendPlugins` can call it. |
38| `next.error` | In a `.catch` handler only. `kind` is `throw` or `timeout` when the hook failed, and `message` is the error's text. `kind` is `re-entry` when the hook was skipped because the event came from inside one of its own mods API calls, and `cause` is `lent` if a method another mod adds to the mods API fired that event. `re-entry` and `cause` require Claude Code v2.1.292 or later. |
38| `next.error` | In a `.catch` handler only. `kind` is `throw` or `timeout` when the hook failed, and `message` is the error's text. `kind` is `re-entry` when the hook was skipped because the event came from inside a mods API call by that hook or by your mod's code outside its hooks. `re-entry` requires Claude Code v2.1.292 or later. |
39| `next.error.cause` | Set only when `kind` is `re-entry`. `rewritten` if a `tool.call` or [`PreToolUse`](/docs/en/hooks#pretooluse) hook changed the mods API call the event came from, or an `agent.spawn` hook changed an agent started by that call. `lent` when a method another mod adds to the mods API fired that event, unless `rewritten` also applies. `lent` requires Claude Code v2.1.292 or later and `rewritten` v2.1.300 or later. |
3940| `next.called` | In a `.catch` handler only. `true` when the hook had called `next`. |
