Add GITHUB_AW_OUTPUT artifact upload with non-empty file validation and logs command awareness

[Copilot]

This PR implements automatic upload of the GITHUB_AW_OUTPUT file as a workflow artifact named aw_output.txt in all generated agentic workflows, with validation to only upload when the output file contains non-empty content. Additionally, the logs command is now aware of and can properly handle this new artifact.

Problem

Previously, the agentic output file (GITHUB_AW_OUTPUT) was created during workflow execution and its contents were set as a workflow output, but the file itself was not persisted as an artifact. This made it difficult to:

• Download and inspect the agent's raw output for debugging
• Enable offline analysis or replay of agentic outputs
• Provide reproducibility for integration tests or end-to-end evaluations

Additionally, there was no validation to prevent uploading empty or non-existent output files as artifacts, and the logs command was not aware of this new artifact type.

Solution

Artifact Upload Implementation

Modified the generateOutputCollectionStep function in pkg/workflow/compiler.go to add an artifact upload step that:

• Uses actions/upload-artifact@v4 to upload the output file
• Names the artifact aw_output.txt for consistent identification
• Uses if: always() && steps.collect_output.outputs.output != '' to ensure upload happens even if previous steps fail, but only when the collection step found non-empty content
• Sets if-no-files-found: warn to handle edge cases where the output file doesn't exist
• Uploads the file referenced by ${{ env.GITHUB_AW_OUTPUT }}

Logs Command Awareness

Enhanced the logs command to be fully aware of the new artifact:

• Detection and Reporting: In verbose mode, specifically detects and reports the presence of aw_output.txt files with human-readable file size information
• Documentation: Updated help text to clearly document all available artifacts including the new agent output file
• Processing: The artifact is automatically downloaded and processed since it uses the .txt extension
• Utilities: Added formatFileSize helper function for consistent file size formatting

Changes

• pkg/workflow/compiler.go: Added artifact upload step to generateOutputCollectionStep function with non-empty content validation
• pkg/workflow/agentic_output_test.go: Updated test to verify the new upload step presence, correct step ordering, and non-empty content validation
• pkg/cli/logs.go: Enhanced to detect, report, and document the new aw_output.txt artifact
• pkg/cli/logs_test.go: Added comprehensive tests for artifact detection and file size formatting
• Generated workflows: All existing workflow lock files were recompiled to include the new artifact upload step with validation

Testing

• All existing tests continue to pass
• New test assertions verify the upload step is present with correct configuration and validation condition
• Added tests for artifact detection in the logs command and file size formatting utilities
• Manual workflow compilation confirms the expected artifact upload step is generated with proper non-empty content checking
• Step ordering is validated: Setup → Execute → Collect → Upload → Other uploads
• Logs command properly detects and reports on the new artifact type

Fixes #126.

@copilot add a check for a non-empty output file if possible

[Copilot]

Added a check for non-empty output file. The upload step now uses if: always() && steps.collect_output.outputs.output != '' which only uploads the artifact when the collection step found non-empty content. This reuses the existing validation logic that checks for file existence and empty content. See commit c01a83d.

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

@copilot make sure the logs command is aware of this new artifact file.

@copilot make sure the logs command is aware of this new artifact file.

The logs command is now aware of the new aw_output.txt artifact. The changes include:

• Specific detection and reporting of aw_output.txt file in verbose mode with file size information
• Updated help text to document all available artifacts including the new agent output file
• Existing functionality automatically downloads and processes the artifact since it's a .txt file
• Added comprehensive tests and file size formatting utilities
