72 Close Session 150

Close-Session 150 Protocol

Core Principle: Never lose progress. Save context before ending, restore context when starting.

What This Skill Does

This skill handles two modes:

💾 SAVE MODE (End of Session)

• Capture current state and progress
• Document key decisions and why
• Define next steps clearly
• Create handoff for next session

🔄 RESTORE MODE (Start of Session)

• Read saved context
• Restore working state
• Verify what's still valid
• Continue seamlessly

When to Use This Skill

SAVE triggers:

• Context window running low
• Ending work session
• Before major context switch
• Handoff to another person/session
• "Save progress", "end session", "preserve context"

RESTORE triggers:

• Starting new session
• Continuing previous work
• "Resume", "continue from last time", "restore context"

The 150% Continuity Rule

• 100% Core: Current state + next steps
• 50% Enhancement: Decision rationale + blockers + risks

Save Protocol

Step 0: GATHER SOURCES (Read First!)

Before saving, collect data from all sources:

Critical: Don't start saving until you've read all sources!

Step 1: EXTRACT LESSONS FROM PROGRESS LOG

Review .session-context.md Progress Log and extract lessons:

• Look for patterns in ❌ (what didn't work)
• Identify root causes from 🔄 (what was tried)
• Confirm solutions from ✅ (what worked)
• Write lessons to MEMORY.md Lessons (Inbox)

Progress Log Analysis:
❌ Failed attempts → Why did they fail? → Principle for future
✅ Successful fixes → What made it work? → Confirm understanding
🔄 Experiments → What was learned? → Document insight

Step 2: SUMMARIZE PROGRESS

What was accomplished:

• Tasks completed
• Current state
• Files changed

Step 3: CAPTURE DECISIONS

Key choices made and why:

• What was decided
• Why this approach
• Alternatives considered

Step 4: DEFINE NEXT STEPS

Clear continuation path:

• Immediate priorities
• What's blocked
• What's ready

Step 5: NOTE CONTEXT

Important state to remember:

• Active files/components
• Dependencies
• Risks/concerns

Integration with Mid-Session Checkpoints

If 74-mid-session-save-150 was used during the session:

Session Flow:
┌─────────────────────────────────────────────────────────┐
│  mid-session-save → mid-session-save → close-session   │
│       ↓                    ↓                 ↓         │
│  Progress Log #1    Progress Log #2    READ ALL LOGS   │
│  (raw data)         (more data)        EXTRACT LESSONS │
│                                        FINAL HANDOFF   │
└─────────────────────────────────────────────────────────┘

Close-session responsibility:

1. Read accumulated Progress Logs from .session-context.md
2. Extract patterns → formulate lessons
3. Write lessons to MEMORY.md Lessons (Inbox)
4. Create final handoff with full context

Where to Save Context

📁 SAVE LOCATIONS
├── MEMORY.md              # Project memory file + extracted lessons
├── .session-context.md    # Session-specific file (read & update)
├── Project README         # For major milestones
└── Git commit message     # For code changes

What to Read vs Write

Operational Rules

1. READ SOURCES FIRST: Gather from .session-context.md, chat, MEMORY.md before saving
2. EXTRACT LESSONS: Don't close without reviewing Progress Log for lessons
3. SAVE BEFORE ENDING: Always save context before session ends
4. RESTORE BEFORE STARTING: Check for saved context when starting
5. BE SPECIFIC: Vague notes are useless later
6. INCLUDE WHY: Decisions without rationale cause confusion
7. PRIORITIZE NEXT STEPS: Make continuation obvious
8. FLAG RISKS: Don't hide problems

Examples

Example: Extracting Lessons from Progress Log

Input: Progress Log from .session-context.md

### Checkpoint #1
❌ Didn't Work: Direct state update in useEffect — infinite loop
   Reason: dependency array included computed object

### Checkpoint #2  
🔄 Tried: useMemo for computed dependency
✅ Worked: useMemo solved the loop — stable reference now

### Checkpoint #3
❌ Didn't Work: Hardcoded colors in component
   Reason: Violates project convention (use themeColors)
✅ Worked: Imported from @/utils/themeColors

Output: Lessons extracted to MEMORY.md

### 2026-01-10 useEffect dependency stability
**Problem:** Infinite loop from computed object in useEffect deps
**Attempts:** Direct state update failed
**Solution:** Use useMemo to create stable reference
**Why it worked:** useMemo memoizes the computed value, preventing new reference on each render
**Principle:** Never use computed objects in useEffect deps — wrap with useMemo or extract primitive IDs

### 2026-01-10 Color convention adherence
**Problem:** Hardcoded colors violated project standards
**Solution:** Import from @/utils/themeColors
**Principle:** All colors must come from central theme utilities, never hardcoded

❌ Bad Session Save

"Was working on stuff. Continue later."
Result: Next session spends 30 min figuring out what "stuff" was

✅ Good Session Save

💾 SESSION-SAVE 150

Progress Made:
- ✅ Created 7 skills from protocols
- ✅ Refactored chain-flow to include action-plan
- 🔄 Working through remaining protocols

Current State:
- Converting PROTOCOLS_GENERALIZED.md to skills
- 7/13 protocols converted

Key Decisions:
| Decision | Reasoning |
|----------|-----------|
| Renamed "Plan-First" → "chain-flow" | It's an orchestrator, not just a plan |
| Separated action-plan as own skill | Needed as component in chains |

Next Steps:
1. **Immediate:** Create session-save-150 (context window low)
2. **Then:** Continue with remaining protocols
3. **Later:** Test skills integration

Context to Remember:
- Skills go in ./skills/ folder
- Each skill needs SKILL.md with yaml frontmatter
- chain-flow orchestrates other skills

Handoff Status: ✅ Ready

Failure Modes & Recovery

Remember: Future you (or next session) will thank present you for good notes. Context loss is expensive — prevention is cheap.
