## Upstream Sync Required

Our \`main\` branch is **${"$"}{BEHIND} commits behind** upstream (\`anthropics/claude-code-action\`).
We are **${"$"}{AHEAD} commits ahead** (our Forgejo-specific changes).

### New upstream commits (latest ${"$"}{BEHIND}, max 30 shown)

\`\`\`
${"$"}{COMMIT_LOG}
\`\`\`

### Files changed

\`\`\`
${"$"}{DIFF_STAT}
\`\`\`

### How to merge

\`\`\`bash
git fetch upstream main
git merge upstream/main
# Resolve any conflicts in the 3-4 modified files (run.ts, tag/index.ts, etc.)
bun test
git push origin main
\`\`\`

### Conflict-prone files

These files have Forgejo modifications and may conflict:
- \`src/entrypoints/run.ts\`
- \`src/modes/tag/index.ts\`
- \`src/mcp/install-mcp-server.ts\`
- \`action.yml\`
