Address Copilot AI feedback:
- Remove underscore support from header names (RFC 7230 compliance)
- Add explicit null check for JSON parsing
- Update validation regex to /^[A-Za-z0-9-]+$/
- Add test case for null value handling
- Update documentation to clarify header name requirements
Changes:
- Header names now only accept alphanumeric characters and hyphens
- Improved error messages for invalid headers
- Added test for null JSON input
- Updated APIM example tests
All 81 tests passing.
This change adds support for custom HTTP headers in AI inference requests,
enabling integration with API Management platforms (Azure APIM, AWS API
Gateway, Kong, etc.) and custom request routing/tracking.
Features:
- New 'custom-headers' input supporting both YAML and JSON formats
- Auto-detection of input format for better UX
- Header name validation (alphanumeric, hyphens, underscores)
- Automatic masking of sensitive headers in logs
- Full backward compatibility (optional parameter)
Changes:
- Added parseCustomHeaders() function in helpers.ts
- Updated InferenceRequest interface with optional customHeaders field
- Modified simpleInference() and mcpInference() to pass headers to OpenAI client
- Added 18 comprehensive test cases
- Updated documentation with examples and use cases
All 80 tests passing. Zero breaking changes.
I mistakenly read the description of the mcp-token field to mean I needed a "PAT for MCP" as if there were a PAT permission for MCP. This change clarifies the language.
This enhancement adds the ability to load a system prompt from a file, similar to
the existing prompt-file functionality, providing more flexibility when working with
complex system prompts.
Key changes:
- Added new `system-prompt-file` input to action.yml with proper description
- Updated main.ts implementation to handle file-based system prompts with:
- File existence checking and appropriate error handling
- Proper precedence (system-prompt-file takes priority over system-prompt)
- Consistent error messages with existing prompt-file implementation
Test coverage added:
- Basic usage: Test verifies system-prompt-file loads content correctly
- Error handling: Test ensures proper errors when system-prompt-file doesn't exist
- Precedence: Test confirms system-prompt-file overrides system-prompt when both exist
- Integration: Test validates both prompt-file and system-prompt-file work together
- Max tokens: Test verifies custom token limits are properly passed to the model
- Testing infrastructure: Improved mock implementations that detect unexpected calls
Documentation:
- Updated README.md with system-prompt-file in inputs table
- Added dedicated usage example for system-prompt-file
- Fixed formatting in inputs table
CI/CD:
- Updated workflow to test system-prompt-file functionality with actual file content
This feature maintains backward compatibility while adding a useful option
for workflows that need to use more complex system prompts stored in files.
