sync-ssot-from-memory

sync-ssot-from-memory is a skill for Claude Code, Codex from Chachamaru127/codex-harness. It costs 70 tokens per session (843 once invoked), scanned A, original, MIT.

A workflow for moving important lessons from temporary memory into a project's single source of truth, or SSOT. It separates recorded decisions from reusable patterns.

In plain words
What is it for?
Use it to promote decisions, discoveries, bug lessons, and recurring methods into the project's decisions and patterns files.
Why use it?
It keeps valuable discoveries from being forgotten or left in scattered memory notes, especially before cleaning up a plans file.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sync-ssot-from-memory scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
