Exclude hybrid environments like Warp from dev background auto-detection by matthewp · Pull Request #17151 · withastro/astro

matthewp · 2026-06-22T21:32:34Z

Changes

Switches agent detection in astro dev from isAgent() to detectAgenticEnvironment().type === "agent", excluding "hybrid" environments from auto-background mode. isAgent() returns true for both "agent" and "hybrid" types, which causes false positives in terminals like Warp that set TERM_PROGRAM=WarpTerminal.
Bumps am-i-vibing from ^0.3.0 to ^0.4.0 which classifies Warp as "hybrid" and includes the latest provider list.

Reported in ascorbic/am-i-vibing#89 and Discord.

Testing

No test changes. The fix is a one-line predicate change in isRunByAgent() and there are no existing tests for agent detection.

Docs

No docs update needed. This is a bug fix to existing behavior.

Hybrid environments like Warp are no longer treated as AI agents for auto-background detection. - [#17158](withastro/astro#17158) [`164df87`](withastro/astro@164df87) Thanks [@ematipico](https://github.com/ematipico)! - Fixes `astro dev --background --host` not listing the network addresses. The background server start output and `astro dev status` now show every exposed network URL, matching the foreground dev server. - [#17141](withastro/astro#17141) [`d785b9d`](withastro/astro@d785b9d) Thanks [@astrobot-houston](https://github.com/astrobot-houston)! - Fixes responsive image CSS overriding user styles defined inside CSS `@layer` blocks. The generated image styles are now wrapped in `@layer astro.images`, ensuring they have lower cascade priority than user-defined layers. - [#17150](withastro/astro#17150) [`1a61386`](withastro/astro@1a61386) Thanks [@matthewp](https://github.com/matthewp)! - Fixes `astro dev --background` failing on Windows with "Failed to spawn background dev server process" </details> --- ### Configuration 📅 **Schedule**: (UTC) - Branch creation - At any time (no schedule defined) - Automerge - At any time (no schedule defined) 🚦 **Automerge**: Disabled by config.
