Plan Gap Analysis

Plan Gap Analysis Skill

Systematically analyze the implementation status of the self-learning memory system by comparing the detailed plans in plans/ against the actual codebase implementation.

Purpose

This skill enables comprehensive gap analysis between:

• Documented plans (Phase 1-6 in plans/ folder)
• Actual implementation (Rust codebase)
• Missing features, tests, and documentation
• Unimplemented components from the roadmap

Workflow

Phase 1: Plan Inventory

1. Read all plan files in plans/ directory:

   • 00-overview.md - Project summary and metrics
   • 01-understand.md - Requirements and components
   • 02-plan.md - Architecture decisions and roadmap
   • 03-execute.md - Implementation details
   • 04-review.md - Quality requirements
   • 05-secure.md - Security requirements
   • 06-feedback-loop.md - Refinements and improvements

2. Extract requirements from each phase:

   • Functional requirements (FR1-FR7)
   • Non-functional requirements (NFR1-NFR6)
   • Data structures and types
   • Functions and APIs
   • Tests and benchmarks
   • Security measures

Phase 2: Codebase Inventory

1. Scan Rust crates structure:

   # List all crates
   find . -name "Cargo.toml" -not -path "*/target/*"
   
   # List all Rust source files
   find . -name "*.rs" -not -path "*/target/*"
   

2. Analyze each crate:

   • memory-core - Core data structures and memory orchestration
   • memory-storage-turso - Turso/libSQL storage backend
   • memory-storage-redb - redb cache layer
   • memory-mcp - MCP server and sandbox
   • test-utils - Test utilities
   • benches - Performance benchmarks

3. Check implementation status:

   • Data structures (Episode, Pattern, Heuristic, etc.)
   • Core functions (start_episode, log_step, complete_episode, etc.)
   • Storage operations (CRUD, queries, sync)
   • Pattern extraction algorithms
   • MCP integration and sandboxing
   • Tests (unit, integration, benchmarks)

Phase 3: Gap Identification

For each phase, identify:

Phase 1 (UNDERSTAND) Gaps

• Missing data structures from specification
• Incomplete type definitions
• Missing edge case handling

Phase 2 (PLAN) Gaps

• Architectural decisions not implemented
• Success metrics not tracked
• Feature flags not implemented
• Circuit breakers missing
• Telemetry not fully implemented

Phase 3 (EXECUTE) Gaps

• Storage agent deliverables incomplete
• Learning agent features missing
• MCP agent sandbox security incomplete
• Sync mechanism not fully implemented

Phase 4 (REVIEW) Gaps

• Compliance tests missing (FR1-FR7)
• Performance tests incomplete (NFR1-NFR6)
• Quality metrics not measured
• Code coverage below 90%
• Integration tests incomplete

Phase 5 (SECURE) Gaps

• Security attack surface analysis missing
• Sandbox escape prevention incomplete
• SQL injection prevention validation missing
• Resource limits not enforced
• Network security not validated
• Penetration tests not implemented

Phase 6 (FEEDBACK LOOP) Gaps

• Edge case refinements not implemented
• Performance optimizations pending
• Two-phase commit not implemented
• Pattern extraction queue missing
• Schema migration not implemented

Phase 4: Prioritization

Categorize gaps by priority:

Critical (Blocks production):

• Security vulnerabilities
• Data corruption risks
• Missing core functionality

High (Affects quality):

• Performance targets not met
• Test coverage below target
• Missing error handling

Medium (Technical debt):

• Code quality issues
• Documentation gaps
• Optimization opportunities

Low (Nice to have):

• Future enhancements
• Optional features
• Cosmetic improvements

Phase 5: TODO Generation

Generate structured TODO list:

## Phase [N]: [PHASE_NAME]

### Critical Priority
- [ ] [Component] - [Missing item] (Week X deliverable)
  - **File**: path/to/file.rs
  - **Plan Reference**: plans/0X-phase.md:LineNumber
  - **Impact**: [Description of impact]
  - **Effort**: [Estimated effort]

### High Priority
- [ ] [Component] - [Missing item]
  ...

### Medium Priority
...

### Low Priority
...
