Fix gh-aw install guard to handle `github/gh-aw` owner-prefix in `gh extension list` output by Copilot · Pull Request #33168 · github/gh-aw

Copilot · 2026-05-18T21:38:28Z

Modern gh CLI outputs extension names with owner prefix (github/gh-aw), but the generated install-guard regex only matched bare gh-aw (at line-start or after whitespace). The guard always evaluated false, causing gh extension install github/gh-aw to be called on an already-installed extension and failing with:

there is already an installed extension that provides the "aw" command

Changes

pkg/workflow/mcp_setup_generator.go — adds |/ to leading-character alternatives in the guard regex so owner/gh-aw format is detected:

-if gh extension list | grep -qE '(^|[[:space:]])gh-aw($|[[:space:]])'; then
+if gh extension list | grep -qE '(^|[[:space:]]|/)gh-aw($|[[:space:]]|$)'; then

pkg/workflow/agentic_workflow_test.go / smoke-copilot.golden — updated to match new pattern
All *.lock.yml workflows — recompiled to pick up the fix

…rmat The grep regex `(^|[[:space:]])gh-aw($|[[:space:]])` failed to match `github/gh-aw` (the format that modern `gh extension list` returns), because `gh-aw` was preceded by `/` rather than whitespace or line start. This caused the guard check to always evaluate false, so the install step would always attempt `gh extension install github/gh-aw` even when the extension was already present, resulting in: there is already an installed extension that provides the "aw" command Fix: add `|/` to the leading-character alternatives so the pattern also matches the `owner/gh-aw` output format: (^|[[:space:]]|/)gh-aw($|[[:space:]]|$) Also update the corresponding test assertion and golden file, and recompile all lock files to propagate the change.
