[Mimir] MVP Build - Phase 1 Complete, Starting Phase 2

Mimir MVP Progress Tracker

Phase 1: Foundation ✅ COMPLETE

Status: Complete and submitted for review
PR: https://github.com/martient/mimir/pull/1
Branch: phase/1-foundation

What Was Implemented

1.1 Project Structure & Build ✅

• Go module initialized (github.com/taultek/mimir)
• Domain-driven directory structure:

  cmd/ - CLI entry points
  internal/ - Application code
  pkg/ - Reusable utilities
  docs/ - Documentation
  scripts/ - Dev tooling
  

• Makefile with targets: build, test, lint, fmt, clean, install, migrate, generate
• .golangci.yml for automated linting
• .gitignore for Go projects

1.2 Configuration System ✅

• YAML-based configuration (~/.mimir/config.yaml)
• Environment variable support (MIMIR_DB_KEY, MIMIR_CONFIG)
• Configuration validation
• Example configuration provided
• Support for:
  • Server config (HTTP/WS ports)
  • Database config (path, encryption key)
  • opencode config (default model)
  • Project registry
  • Webhook configuration
  • Cron jobs

1.3 Core Server ✅

• HTTP server using Go standard library
• Health check endpoint (GET /health)
• Metrics endpoint (GET /metrics - Prometheus format)
• JSON responses
• Graceful shutdown support
• Request logging middleware
• Response status tracking

1.4 Observability ✅

• Structured JSON logging
• Request metadata logging (method, path, status, duration)
• Logger interface with Info, Error, Warn, Debug methods
• Metrics collection framework
• Prometheus format export

1.5 CLI Interface ✅

• CLI framework using Cobra
• Commands implemented:
  • mimir serve - Start gateway (placeholder)
  • mimir status - Show gateway status
  • mimir projects list - List projects (placeholder)
  • mimir projects add <path> - Register project (placeholder)
  • mimir send - Send message (placeholder)
• Help system
• Flag handling

Testing Status

• ✅ Application builds successfully
• ✅ All CLI commands execute
• ✅ Server starts without errors
• ✅ Health check returns JSON
• ✅ Graceful shutdown works

Dependencies Added

• github.com/spf13/cobra - CLI framework
• gopkg.in/yaml.v3 - Configuration parsing
• github.com/jmoiron/sqlx - Database helpers (for Phase 2)
• github.com/mutecomm/go-sqlcipher - SQLite encryption (for Phase 2)
• github.com/google/uuid - UUID generation (for Phase 2)

Architecture Decisions

1. Using Go standard library for HTTP server initially

   • Echo v4 had module resolution issues
   • Will add Echo in later phase when needed for WebSocket

2. Simple logging for Phase 1

   • Structured logging implemented
   • Will add request IDs in later phases

3. Configuration approach

   • YAML for easy editing
   • Environment variables for secrets
   • Validation to catch errors early

Next Phase: Core Services (Phase 2)

Phase 2 will implement:

• Database layer with SQLite + sqlcipher
• Session management (CRUD)
• Project registry (CRUD)
• Enhanced CLI with real operations
• Database migrations

Phase 2: Core Services 🔄 IN PROGRESS

Status: Started
Estimated Duration: 2 weeks

Tasks

• Database layer initialization
• Session CRUD operations
• Project CRUD operations
• Database migrations
• Enhanced CLI commands
• Integration testing

Phase 3+: Pending

Phase 3: opencode Integration
Phase 4: AGENTS Foundation
Phase 5: Git Worktree Isolation
Phase 6: GitHub Integration
Phase 7: Webhook System
Phase 8: Sentry Workflow
Phase 9: Plugin System
Phase 10: Cron/Scheduler
Phase 11: Testing & Polish

Start with the Phase 2 task list and the existing entry points in cmd/main.go, internal/app/container.go, and internal/config/config.go. The issue does not identify implementation files or tests for the database, CRUD, migration, CLI, and integration work. Done would require completing all checked Phase 2 tasks and passing the resulting integration tests.
