# v0.3.6

> 2026-03-06

Task lifecycle hooks, custom template registries, parent-child subtasks, and PreToolUse hook fix.

## Enhancements

* **Custom template registries**: `trellis init --registry` supports fetching Spec templates from custom GitHub/GitLab/Bitbucket repositories. Automatically detects marketplace mode (`index.json`) and direct download mode
* **Task lifecycle hooks**: `.trellis/config.yaml` gains a `hooks` configuration block supporting four events: `after_create`, `after_start`, `after_finish`, and `after_archive`. Task information is passed via the `TASK_JSON_PATH` environment variable. Ships with a Linear sync hook example. See: [Task Management](/start/everyday-use)
* **Parent-child subtasks**: `task.py add-subtask` / `remove-subtask` commands for linking tasks. `task.json` gains `children`, `parent`, and `meta` fields. `task.py create --parent` creates a child task directly
* **Record-session prompt improvement**: Archive decision is now based on actual work state rather than the `task.json` status field
* **Brainstorm prompt update**: `/brainstorm` now includes a subtask decomposition step for complex tasks

## Bug Fixes

* **PreToolUse context injection failure**: Claude Code v2.1.63 renamed its internal tool from `Task` to `Agent` ([anthropics/claude-code#29677](https://github.com/anthropics/claude-code/issues/29677)), causing hook scripts with `tool_name != "Task"` checks to exit early. This broke code-spec context injection for all implement/check/debug/research agents. Fix: accept both `Task` and `Agent` tool names, and add an `"Agent"` matcher to `settings.json`

## Migration

No manual migration required. Run `trellis update` to sync the updated hook scripts and settings.
