PR Description: Sync safe-outputs.md with release v0.74.8 schema

Classification

• Type: documentation
• Scope: safe-outputs schema documentation
• Breaking Changes: none
• Deprecations: reviewers and team-reviewers fields in add-reviewer (backward-compatible aliases)

Summary

Updates the safe-outputs documentation to reflect schema changes introduced in release v0.74.8. Adds per-output patch size/file limit configuration for create-pr and push-changes outputs, and renames reviewer fields in add-reviewer for consistency while maintaining backward compatibility.

Changes by File

.github/aw/safe-outputs.md (modified)

Impact: high
Breaking: false

Added Features

1. Per-output patch constraints for create-pr safe-output:

   • max-patch-size (optional): Override global patch size limit for this specific output
   • max-patch-files (optional): Override global patch file count limit for this specific output

2. Per-output patch constraint for push-changes safe-output:

   • max-patch-size (optional): Override global patch size limit for this specific output

Field Renames (Backward Compatible)

3. Standardized reviewer field names in add-reviewer safe-output:
   • reviewers → allowed-reviewers (old name deprecated but still supported)
   • team-reviewers → allowed-team-reviewers (old name deprecated but still supported)
   • Deprecation note added to documentation
   • No breaking change: legacy field names remain functional as aliases

Technical Details

• Schema Version: v0.74.8
• File Type: Markdown documentation
• Diff Stats: Documentation-only (no code changes)
• Backward Compatibility: Fully maintained via deprecated field aliases

Agentic Workflow Impact

This update enables:

1. Granular control: Workflows can now set per-output patch constraints, allowing different size limits for different PR creation scenarios
2. Consistency: The allowed-* prefix aligns reviewer field naming with standard conventions for allowlist configurations
3. Migration path: Existing workflows using reviewers/team-reviewers continue to function without modification
