Local pull request checkout always fails on Azure DevOps. T3 Code passes --detect true, and az repos pr checkout has no such parameter:
| 1 | $ az repos pr checkout --only-show-errors --detect true --id 1 --remote-name origin |
| 2 | ERROR: unrecognized arguments: --detect true |
Worktree checkouts take a different path and are not affected.
Fixes #31164
Drop --detect true from AzureDevOpsCli.checkoutPullRequest. The extension's checkout(id, remote_name) always reads the organization from the current remote, so nothing replaces it.
This is a very small fix for an obvious bug: one flag the command rejects, confirmed by running it, plus a test. #21838 does not fix this, because it swaps the flag for --detect false --organization ... and the command accepts neither. If that PR lands first, its executor will need to skip this command.

I did not click through this in the app.
A trap this fix makes reachable: az runs git fetch, git checkout and git pull with check=False, so a failed git checkout still runs the pull and exits 0. In a single-branch clone I saw it merge the PR into the current branch instead of switching. Normal clones are fine. az also marks the branch as a favorite on the server for each checkout. Replacing az repos pr checkout with plain git would remove both, but that is a separate change.

Verdict: Needs Human Approval
Macroscope's review found this PR requires human approval — This restores Azure DevOps local PR checkout by removing an unsupported flag. However, the author's reproduction shows the now-reachable command can silently merge into the current branch in single-branch clones; that exposure needs an explicit decision or safeguard.

Azure DevOps pull request checkout now uses Git to fetch and switch to the pull request’s head branch. The provider rejects fork pull requests and handles existing and missing local branches. The Azure CLI checkout method was removed.

019f8Local Azure DevOps PR checkout now uses Git directly instead of the failing Azure CLI command, and the main failure from the linked issue should be fixed. The remaining risk is a weak unit test that would not catch a wrong remote or branch in the existing-branch fetch. The change is mergeable with minor follow-up.

Explanation
The title names the main change: local pull request checkout on Azure DevOps no longer fails because of the --detect flag. It follows conventional commit form and is specific, so it matches the changeset, which removes --detect true from the az repos pr checkout call.
Explanation
The description follows the template. It has Problem, Change, Scope, and Verification sections, with a conventional-style context and a clear reproduction log. It links issue #31164 and explains why #21838 does not fix the bug. It gives focused verification (a failing-then-passing argument test, check:changed, and a real-PR run). It also states what was not checked (the in-app flow) and notes the single-branch risk. The template's optional agent-model line is present. The Change section is brief but adequate for a small fix. The description does not include a UI screenshot, but the change has no UI impact, so this does not block the check.
Explanation
For [#31164], the whole-PR change removes AzureDevOpsCli.checkoutPullRequest, which passed the rejected --detect true flag. AzureDevOpsSourceControlProvider.checkoutChangeRequest no longer calls az repos pr checkout. It reads the PR with azure.getPullRequest, then uses git: fetchRemoteTrackingBranch for an existing local branch, fetchRemoteBranch into a new local branch otherwise, and then switchRef. The rejected command is gone, so the reported unrecognized arguments: --detect true error cannot occur. The local checkout objective is met by a different mechanism than the PR description states (the description says only the flag is removed). The raw summary reports a provider test for both the missing-branch and existing-branch cases; that test was not read in this assessment. The previous PASS relied on an argument test for the removed call, which no longer applies.
Explanation
All changed code serves the local checkout path for [#31164]. The provider change replaces the failing az repos pr checkout call with git operations that implement the same checkout. The added fork rejection and the existing-branch fetch-only handling are part of that checkout logic. The removed checkoutPullRequest method is only reachable from this path. The change is broader than the PR description, which says replacing the Azure CLI with plain git is a separate change. The description should be updated to match the code, but this is not an unrelated change.

Note
Written by claude-opus-5-5 on behalf of Maria
Not changing this here. The fetch, checkout and pull all run inside one az repos pr checkout subprocess (check=False in the extension), so T3 Code has no point between the failed checkout and the pull to stop it. The only fix is to replace az repos pr checkout with plain git, which the PR body already calls out as a separate change. This PR stays scoped to the rejected --detect flag; normal clones check out correctly.
@maria-rcks Understood. The proposed mockRun test cannot verify or stop operations inside the az subprocess. The single-branch risk remains, but I understand the fix is outside this PR’s scope.
Would you like me to open a follow-up issue?
