codex-harness: Skill for Claude Code

Sync SSOT from Memory

Promote important observations recorded in memory systems (Claude-mem or Serena) to the project's SSOT: .claude/memory/decisions.md and .claude/memory/patterns.md.

Quick Reference

• "Save what we learned for next time" → this skill
• "Promote important decisions to SSOT" → this skill
• "Organize decisions (why) and methods (how) separately" → Reflect in decisions/patterns separately

Supported Memory Systems

System	Detection	How to Get Observations
Claude-mem	~/.claude-mem/settings.json	mcp__plugin_claude-mem_mcp-search__search
Serena	.serena/memories/	mcp__serena__read_memory

Auto-detected at execution, using available system.

Execution Flow

Step 0: Detect Memory System

# Claude-mem check
if [ -f "$HOME/.claude-mem/settings.json" ]; then
  MEMORY_SYSTEM="claude-mem"
fi

# Serena check
if [ -d ".serena/memories" ]; then
  MEMORY_SYSTEM="serena"
fi

Step 1: Extract SSOT Promotion Candidates

For Claude-mem:

• Search for type:decision
• Search for type:discovery concepts:pattern
• Search for type:bugfix concepts:gotcha

For Serena:

• List and read relevant memories

Step 2: Filter by Promotion Criteria

Decisions Candidates (Why) → decisions.md:

• Technology selection reasons
• Guardrail reasons
• User requirements/constraints

Patterns Candidates (How) → patterns.md:

• Recurrence prevention (bugfixes)
• Reusable solutions
• Implementation patterns

Exclusions:

• Work-in-progress rough notes
• Personal/confidential information
• One-time tasks (not reusable)

Step 3: Reflect to SSOT

Add entries to decisions.md and patterns.md with:

• Unique ID (D{N} or P{N})
• Date, Tags, Observation ID
• Structured content (Conclusion, Background, Options, etc.)

Step 4: Output Summary

## SSOT Promotion Results

### Added/Updated
| File | Item | Observation ID |
|------|------|----------------|
| decisions.md | D{N}: {Title} | #{id} |
| patterns.md | P{N}: {Title} | #{id} |

### Excluded
- Work-in-progress: N items
- Duplicates: N items
