New Features

Feature	Issue	Description
MCP Server	#59	Claude Code integration via Model Context Protocol
Provider Fallback	#65	Automatic failover between OpenAI/Anthropic/VertexAI
Structured Output	#64	JSON Schema-compliant AI responses
Auto-Triage	#63	AI-powered issue priority/category classification
First Response	#62	Automated incident response guide generation
Timeline	#60	Incident activity timeline visualization
Runbook	#55	Incident response procedure suggestions
Postmortem	#56	Post-incident documentation generation
Slack Integration	#54	Webhook notifications for alerts
Analysis Command	#58	Root cause analysis support
Docker Support	#24	Containerized deployment with distroless

New Commands

• /analysis - Root cause analysis
• /postmortem - Post-incident documentation
• /runbook - Response procedure suggestions
• /timeline - Activity timeline

Infrastructure

• Go 1.24: Upgraded with tool directive support
• GoReleaser: Multi-binary releases (alert-menta, alert-menta-mcp, alert-menta-triage, alert-menta-firstresponse)
• Security Scanning: govulncheck, gosec workflows
• Dependabot: Automated dependency updates
• Docker: Multi-stage build with distroless runtime

Go 1.24 Best Practices

• Tool directive in go.mod for gosec, govulncheck, gofumpt
• go tool <name> for tool execution
• Centralized tool version management

Code Quality

• Refactored CLAUDE.md into modular .claude/ structure (399 → 47 lines)
• Fixed all linting issues (gocyclo, staticcheck)
• Added -version flag to CLI

Binaries Built

Binary	Description
alert-menta	Main CLI
alert-menta-mcp	MCP server for Claude Code
alert-menta-triage	Auto-triage CLI
alert-menta-firstresponse	First response guide CLI

Platforms Supported

• linux/amd64, linux/arm64
• darwin/amd64, darwin/arm64
• windows/amd64, windows/arm64

Test Plan

• All unit tests pass
• E2E tests pass
• Lint checks pass
• govulncheck pass
• gosec pass
• GoReleaser dry-run succeeds

Breaking Changes

• Go version requirement: 1.24+

The error from GetSchemaJSON is being silently ignored. If schema marshaling fails, the AI won't receive schema instructions, potentially leading to incorrect output format. Consider logging the error or handling it explicitly.

Suggested change

	if err == nil && schemaJSON != nil {
	if err != nil {
	return "", fmt.Errorf("failed to get structured output schema JSON: %w", err)
	}
	if schemaJSON != nil {

[Copilot]

Similar to VertexAI, the error from GetSchemaJSON is silently ignored. The else branch provides a generic JSON instruction without the schema, which may not produce the expected structure. Consider logging the marshaling error or returning it.

Suggested change

	if err == nil && schemaJSON != nil {
	systemPrompt += fmt.Sprintf("\n\nYou MUST respond with valid JSON that conforms to this schema:\n```json\n%s\n```\nRespond ONLY with the JSON object, no additional text.", string(schemaJSON))
	} else {
	systemPrompt += "\n\nYou MUST respond with valid JSON. Respond ONLY with the JSON object, no additional text."
	}
	if err != nil {
	return "", fmt.Errorf("failed to get structured output schema: %w", err)
	}
	if schemaJSON == nil {
	return "", fmt.Errorf("failed to get structured output schema: schema is nil")
	}
	systemPrompt += fmt.Sprintf("\n\nYou MUST respond with valid JSON that conforms to this schema:\n```json\n%s\n```\nRespond ONLY with the JSON object, no additional text.", string(schemaJSON))
