# v0.5.18

> 2026-05-19

## Bug Fixes

### Archived task create collisions

`task.py create` now rejects a slug that already exists in `.trellis/tasks/archive/**`.

* Checks archived task directories before creating a new active task directory
* Prints the archived path that caused the collision
* Tells the user to choose a new slug for an intentional new task

### Workflow-state tool routing

`[workflow-state:in_progress]` now distinguishes sub-agent types from skills.

* `trellis-implement` and `trellis-research` are sub-agent types only
* `trellis-update-spec` is a skill
* `trellis-check` exists as both; verification after code changes should prefer the Agent form
* Prevents agents from trying to call missing `trellis-implement` / `trellis-research` skills

### Codex multi\_agent\_v2 timeout bounds

`.codex/config.toml` now emits the `multi_agent_v2` wait timeout values as a valid bounds set for Codex CLI 0.131+.

```toml theme={null}
[features.multi_agent_v2]
enabled = true
max_concurrent_threads_per_session = 6
min_wait_timeout_ms = 480000
default_wait_timeout_ms = 480000
max_wait_timeout_ms = 3600000
```

* Fixes Codex startup failure: `default_wait_timeout_ms must be at least min_wait_timeout_ms`
* Keeps the Trellis default wait at 8 minutes
* Keeps the explicit upper clamp at 1 hour
* Covers fresh `trellis init` and template refresh through `trellis update`

## Upgrade

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

No migration command is required.
