Summary

Fixes #85 by adding 2>&1 to redirect stderr to stdout when capturing the version from gh aw version.

Problem

gh aw version writes its output to stderr, not stdout. The current command in upgrade.yml:

version=$(gh aw version | awk '{print $NF}')

This pipes only stdout, resulting in an empty $version variable, which causes:

• Empty .github/aw/gh-aw-version file
• PR titles like "build: Upgrade gh-aw to " (missing version)
• Commit messages with missing version numbers

Solution

Changed line 55 in .github/workflows/upgrade.yml to:

version=$(gh aw version 2>&1 | awk '{print $NF}')

The 2>&1 redirects stderr (file descriptor 2) to stdout (file descriptor 1), allowing the pipe to capture the version string.

Validation

Tested with a simulation that mimics gh aw version writing to stderr:

• Without 2>&1: version variable is empty ✗
• With 2>&1: version correctly captured as v0.87.10 ✓

The fix aligns with the existing pattern already used in the justfile (line 12).

Review complete ✓

Checked:

• Correctness: 2>&1 properly redirects stderr to stdout for version capture
• Consistency: Matches the existing pattern in justfile line 12
• Impact: Ensures version propagates to .github/aw/gh-aw-version, PR titles, and commit messages
• Safety: Minimal change with no behavioral side effects

Verdict: Ready to merge. The fix solves the empty version variable issue by aligning with the repository's established stderr capture pattern.
