See the [v0.6.15](/changelog/v0.6.15), [v0.6.16](/changelog/v0.6.16) and [v0.6.17](/changelog/v0.6.17) changelogs for detail.

## Enhancements

### DeepSeek Harness native sub-agents

On the 0.7 beta line, `trellis init --dsh` installs native research / implement / check sub-agent skills (`trellis-agent-{research,implement,check}`). Stable 0.6.15 still runs those phases inline. (#548)

* Child-only role skills; the main session does not load them
* Uses the companion `dsh-trellis` `trellis_wait` when present; otherwise foreground dispatch. No polling
* Nested-host session identity prefers `DSH_TRELLIS_CONTEXT_ID`, then `DSH_SHELL=1` plus `DSH_SESSION_ID`

## Bug Fixes

### Spec-injection YAML flow lists

`parse_simple_yaml` in `trellis_config.py` now parses scalar flow sequences such as `spec_injection.tools: []` and `tools: [Edit, Write]`. Nested `[]` / `{}` are still rejected.

### `task.py workflow`

`task.py workflow` imports `read_json` from `common.io`, so pinning a per-task workflow no longer raises `NameError`.

## Upgrade

```bash theme={null}
npm install -g @mindfoldhq/trellis@beta
trellis update
```

No `--migrate` required.
