# Suggested Opening Prompt for Next Session
|
||||
|
||||
**Context**: First session with Anthropic API Memory system
|
||||
**Project**: Tractatus multi-project AI governance platform
|
||||
**Current Phase**: Testing & API Memory observation
|
||||
|
||||
---
|
||||
|
||||
## Recommended Opening Prompt
|
||||
|
||||
```
|
||||
I'm continuing work on the Tractatus project. This is the FIRST SESSION using
|
||||
Anthropic's new API Memory system.
|
||||
|
||||
Primary goals:
|
||||
1. Run node scripts/session-init.js and observe framework initialization
|
||||
2. Fix 3 MongoDB persistence test failures (1-2 hours estimated)
|
||||
3. Investigate BoundaryEnforcer trigger logic (inst_016-018 compliance)
|
||||
4. Document API Memory behavior vs. file-based system
|
||||
|
||||
Key context to observe:
|
||||
- Do the 19 HIGH-persistence instructions load automatically?
|
||||
- Does session-init.js detect previous session via API Memory?
|
||||
- How does context pressure behave with new Memory system?
|
||||
- What's the session length before compaction?
|
||||
|
||||
After initialization, start with: npm test -- --testPathPattern="tests/unit"
|
||||
to diagnose framework test failures.
|
||||
|
||||
Read docs/SESSION_HANDOFF_2025-10-10.md for full context from previous session.
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Why This Prompt Works
|
||||
|
||||
### 1. **Establishes Context Immediately**
|
||||
- "Continuing work on Tractatus" - Project continuity
|
||||
- "FIRST SESSION with API Memory" - Critical context
|
||||
- Links to handoff document - Full session history
|
||||
|
||||
### 2. **Clear Priorities**
|
||||
- Primary goal: Observe API Memory behavior (new system testing)
|
||||
- Secondary goal: Fix test failures (blocking work)
|
||||
- Tertiary goal: Investigate framework issue (quality improvement)
|
||||
|
||||
### 3. **Explicit Observation Tasks**
|
||||
- Questions about instruction loading
|
||||
- Session detection behavior
|
||||
- Context pressure patterns
|
||||
- Session length metrics
|
||||
|
||||
### 4. **Actionable Next Steps**
|
||||
- Run session-init.js (mandatory framework start)
|
||||
- Run unit tests (diagnostic)
|
||||
- Read handoff doc (full context)
|
||||
|
||||
### 5. **Leverages API Memory**
|
||||
- Mentions "19 HIGH-persistence instructions" (test if Memory knows this)
|
||||
- References previous session (test continuity)
|
||||
- Links to specific files (test Memory's file awareness)
|
||||
|
||||
---
|
||||
|
||||
## Alternative: Shorter Version
|
||||
|
||||
If you prefer concise:
|
||||
|
||||
```
|
||||
Tractatus project - FIRST session with API Memory. Run session-init.js,
|
||||
observe framework behavior, fix test failures, then begin Phase 1.
|
||||
See docs/SESSION_HANDOFF_2025-10-10.md for context.
|
||||
```
|
||||
|
||||
**Pros**: Fast, direct
|
||||
**Cons**: Less context for Memory system to latch onto
|
||||
|
||||
---
|
||||
|
||||
## Alternative: Explicit Testing Version
|
||||
|
||||
If you want to test Memory explicitly:
|
||||
|
||||
```
|
||||
Tractatus project continuation. BEFORE running session-init.js:
|
||||
|
||||
Question 1: Do you remember the 19 active instructions from previous session?
|
||||
Question 2: Can you summarize the current project status?
|
||||
Question 3: What were we working on before this session started?
|
||||
|
||||
Then run session-init.js and compare file-based vs. Memory-based context.
|
||||
```
|
||||
|
||||
**Pros**: Direct Memory system test
|
||||
**Cons**: More manual, less workflow-oriented
|
||||
|
||||
---
|
||||
|
||||
## Recommended Approach
|
||||
|
||||
**Use the first prompt** (recommended version) because:
|
||||
1. ✅ Natural workflow continuation
|
||||
2. ✅ Tests Memory implicitly while working
|
||||
3. ✅ Establishes priorities clearly
|
||||
4. ✅ Maintains framework discipline (session-init first)
|
||||
5. ✅ Balances observation with productivity
|
||||

## What to Watch For in Response
|
||||
|
||||
### Indicators API Memory is Working
|
||||
|
||||
1. **Claude references previous session details** without reading files
|
||||
- Mentions "concurrent session architecture" work
|
||||
- Knows about inst_018 correction
|
||||
- Recalls BoundaryEnforcer investigation need
|
||||
|
||||
2. **Claude knows instruction count** before reading instruction-history.json
|
||||
- "I see we have 19 active instructions"
|
||||
- References specific instructions (inst_016, 017, 018, 019)
|
||||
|
||||
3. **Claude describes project status** without reading handoff
|
||||
- Knows we're at Phase 1 (after test fixes)
|
||||
- Mentions 50-64 hours remaining
|
||||
- References implementation plan
|
||||
|
||||
### Indicators API Memory is NOT Working (Yet)
|
||||
|
||||
1. **Claude asks basic questions** about project
|
||||
- "What is Tractatus?"
|
||||
- "What phase are we in?"
|
||||
- "What should I work on?"
|
||||
|
||||
2. **Claude needs to read files** for basic context
|
||||
- Immediately reads instruction-history.json
|
||||
- Reads handoff document for status
|
||||
- Asks for clarification on priorities
|
||||
|
||||
3. **Claude treats this as brand new session**
|
||||
- Doesn't reference previous work
|
||||
- Starts from scratch with framework
|
||||
- No continuity with past decisions
|
||||
|
||||
---
|
||||
|
||||
## Expected Outcomes
|
||||
|
||||
### Best Case (API Memory Excellent)
|
||||
- Claude knows project status immediately
|
||||
- Session lasts 100-150 messages before compaction
|
||||
- Post-compaction continuation is seamless
|
||||
- Framework state persists without file reads
|
||||
|
||||
### Realistic Case (API Memory Good)
|
||||
- Claude has general context, needs some file reads
|
||||
- Session lasts 50-80 messages before compaction
|
||||
- Post-compaction is noticeably better than before
|
||||
- Some framework state preserved
|
||||
|
||||
### Worst Case (API Memory Not Active Yet)
|
||||
- Behavior identical to previous sessions
|
||||
- 20-40 messages before compaction
|
||||
- Full file reads needed for context
|
||||
- session-init.js works exactly as before
|
||||
|
||||
**All cases are acceptable** - we're in observation mode, not optimization mode.
|
||||
|
||||
---
|
||||
|
||||
## Post-Session Data Collection
|
||||
|
||||
After next session, document:
|
||||
|
||||
1. **Session Length**: How many messages before compaction?
|
||||
2. **File Operations**: Did session-init.js read all files?
|
||||
3. **Instruction Persistence**: Were instructions auto-loaded?
|
||||
4. **Context Continuity**: Did Claude remember previous session?
|
||||
5. **Compaction Experience**: Was post-compaction handoff smoother?
|
||||
|
||||
This data informs:
|
||||
- Phase 1 of session-init.js optimization (30 mins)
|
||||
- Phase 4 implementation of inst_019 (4-6 hours)
|
||||
- Phase 3.5 concurrent session architecture (4-6 hours)

# Session Init API Memory Audit & Optimization Plan
|
||||
|
||||
**Date**: 2025-10-10
|
||||
**Context**: Preparing for first session with Anthropic API Memory system
|
||||
**Script**: `scripts/session-init.js`
|
||||
|
||||
---
|
||||
|
||||
## Current Implementation Analysis
|
||||
|
||||
### What session-init.js Does Now
|
||||
|
||||
1. **Checks Session Status** (lines 66-85)
|
||||
- Reads `.claude/session-state.json` to detect new vs. continued session
|
||||
- Uses file timestamp and message count to determine status
|
||||
- **File-dependent**: Requires file to exist for detection
|
||||
|
||||
2. **Initializes Session State** (lines 90-144)
|
||||
- Creates/overwrites `.claude/session-state.json`
|
||||
- Sets up framework activity tracking
|
||||
- **File-based**: All state stored in JSON file
|
||||
|
||||
3. **Resets Token Checkpoints** (lines 149-165)
|
||||
- Creates/overwrites `.claude/token-checkpoints.json`
|
||||
- Sets 25%, 50%, 75% milestones
|
||||
- **File-based**: Checkpoint state in JSON
|
||||
|
||||
4. **Loads Instruction History** (lines 170-193)
|
||||
- Reads `.claude/instruction-history.json` (6k+ tokens)
|
||||
- Counts active instructions by persistence/quadrant
|
||||
- **File-dependent**: Requires full file read
|
||||
|
||||
5. **Runs Pressure Check** (lines 198-218)
|
||||
- Executes `check-session-pressure.js` as subprocess
|
||||
- Parses output to extract pressure level/score
|
||||
- **Independent**: Should work with API Memory
|
||||
|
||||
6. **Runs Framework Tests** (lines 288-323)
|
||||
- Executes unit tests for 5 framework components
|
||||
- Reports pass/fail status
|
||||
- **Independent**: Should work with API Memory
|
||||
|
||||

|
||||
|
||||
## API Memory System Implications
|
||||
|
||||
### What API Memory SHOULD Provide
|
||||
|
||||
1. **Automatic Instruction Persistence**
|
||||
- 19 instructions might be available without reading file
|
||||
- Framework context might persist across sessions
|
||||
- Session state might be remembered
|
||||
|
||||
2. **Session Continuity Detection**
|
||||
- API Memory knows if this is a continuation
|
||||
- Can detect compaction events
|
||||
- May preserve session metadata
|
||||
|
||||
3. **Reduced File Dependency**
|
||||
- Less need to read large JSON files
|
||||
- State could be queried from Memory API instead
|
||||
- Faster initialization
|
||||
|
||||
### What API Memory CANNOT Replace
|
||||
|
||||
1. **Local File State** (still needed)
|
||||
- Other tools may read these files
|
||||
- Backward compatibility
|
||||
- Debugging and auditing
|
||||
|
||||
2. **Explicit Framework Initialization**
|
||||
- Components still need setup
|
||||
- Tests still need to run
|
||||
- Checkpoints still need tracking
|
||||
|
||||
---
|
||||
|
||||
## Optimization Recommendations
|
||||
|
||||
### Priority 1: API Memory Detection (IMMEDIATE)
|
||||
|
||||
**Add at session start:**
|
||||
```javascript
|
||||
/**
|
||||
* Detect if API Memory system is active
|
||||
* This is indicated by system providing context without file reads
|
||||
*/
|
||||
function detectAPIMemory() {
|
||||
// Check for API Memory system hints
|
||||
// (Implementation depends on Anthropic's API Memory design)
|
||||
|
||||
// For now, we can infer from environment or test query
|
||||
const hasAPIMemory = process.env.ANTHROPIC_API_MEMORY === 'true' ||
|
||||
process.env.CLAUDE_CODE_VERSION?.includes('memory');
|
||||
|
||||
return {
|
||||
available: hasAPIMemory,
|
||||
detected: hasAPIMemory ? 'API Memory system detected' : 'File-based system (legacy)'
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- Inform user if new system is active
|
||||
- Adjust behavior based on memory availability
|
||||
- Collect data on memory system effectiveness
|
||||
|
||||
### Priority 2: Conditional File Reads (MEDIUM)
|
||||
|
||||
**Optimize instruction loading:**
|
||||
```javascript
|
||||
function loadInstructionHistory() {
|
||||
// If API Memory available, try lightweight query first
|
||||
if (apiMemoryAvailable) {
|
||||
try {
|
||||
// Query memory for instruction count without full file read
|
||||
const memoryStats = queryAPIMemoryStats();
|
||||
if (memoryStats.instructionsLoaded) {
|
||||
log(' Instructions loaded via API Memory', 'green');
|
||||
return memoryStats;
|
||||
}
|
||||
} catch (err) {
|
||||
// Fall back to file read
|
||||
}
|
||||
}
|
||||
|
||||
// Original file-based implementation
|
||||
const history = JSON.parse(fs.readFileSync(INSTRUCTION_HISTORY_PATH, 'utf8'));
|
||||
// ... rest of function
|
||||
}
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- Reduces 6k token file read if Memory has instructions
|
||||
- Faster initialization
|
||||
- Still works if Memory system unavailable
|
||||
|
||||
### Priority 3: Session Continuity Intelligence (MEDIUM)
|
||||
|
||||
**Enhanced session detection:**
|
||||
```javascript
|
||||
function isNewSession() {
|
||||
// Check API Memory first
|
||||
if (apiMemoryAvailable) {
|
||||
try {
|
||||
const memorySession = queryAPIMemorySession();
|
||||
if (memorySession.sessionId) {
|
||||
return {
|
||||
isNew: false,
|
||||
isToday: true,
|
||||
sessionState: memorySession,
|
||||
source: 'api_memory'
|
||||
};
|
||||
}
|
||||
} catch (err) {
|
||||
// Fall back to file
|
||||
}
|
||||
}
|
||||
|
||||
// Original file-based detection
|
||||
// ... existing implementation
|
||||
}
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- Better post-compaction detection
|
||||
- Smoother session continuation
|
||||
- Reduced file dependency
|
||||
|
||||
### Priority 4: API Memory Instrumentation (LOW - DATA COLLECTION)
|
||||
|
||||
**Add tracking for next session:**
|
||||
```javascript
|
||||
function reportAPIMemoryStats() {
|
||||
if (!apiMemoryAvailable) return;
|
||||
|
||||
section('API Memory System Status');
|
||||
success('API Memory: ACTIVE (Experimental)');
|
||||
|
||||
try {
|
||||
const stats = {
|
||||
instructionsPersisted: queryInstructionPersistence(),
|
||||
sessionContextPreserved: querySessionContext(),
|
||||
compactionHandled: queryCompactionStatus()
|
||||
};
|
||||
|
||||
log(` Instructions persisted: ${stats.instructionsPersisted}`, 'cyan');
|
||||
log(` Session context: ${stats.sessionContextPreserved}`, 'cyan');
|
||||
log(` Post-compaction: ${stats.compactionHandled}`, 'cyan');
|
||||
} catch (err) {
|
||||
warning(`Could not query API Memory stats: ${err.message}`);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- Understand how API Memory works
|
||||
- Collect data for future optimization
|
||||
- Identify gaps in Memory system
|
||||
|
||||
---
|
||||
|
||||
## Implementation Strategy
|
||||
|
||||
### Phase 1: Detection (Next Session - 30 mins)
|
||||
1. Add `detectAPIMemory()` function
|
||||
2. Report API Memory status in output
|
||||
3. Set flag for conditional behavior
|
||||
4. **No breaking changes** - purely informational
|
||||
|
||||
### Phase 2: Optimization (Future Session - 2 hours)
|
||||
1. Implement conditional file reads
|
||||
2. Add Memory-based session detection
|
||||
3. Reduce redundant operations
|
||||
4. **Maintain backward compatibility**
|
||||
|
||||
### Phase 3: Instrumentation (Future Session - 1 hour)
|
||||
1. Add Memory system metrics
|
||||
2. Track effectiveness
|
||||
3. Identify optimization opportunities
|
||||
4. **Data collection for refinement**
|
||||
|
||||
---
|
||||
|
||||
## Testing Plan
|
||||
|
||||
### Next Session Tests
|
||||
|
||||
1. **Does API Memory preserve instructions?**
|
||||
- Test: Start session, check if 19 instructions accessible without file read
|
||||
- Expected: Yes (instructions available via Memory)
|
||||
- Fallback: No (still reads from file)
|
||||
|
||||
2. **Does API Memory detect continuation?**
|
||||
- Test: After compaction, does Memory know previous session?
|
||||
- Expected: Yes (session context preserved)
|
||||
- Fallback: No (treats as new session)
|
||||
|
||||
3. **Does API Memory reduce file operations?**
|
||||
- Test: Count file reads in session-init.js
|
||||
- Baseline: 3 file reads (session-state, instruction-history, token-checkpoints)
|
||||
- Expected: 1-2 file reads (some via Memory)
|
||||
|
||||
4. **Does API Memory extend session length?**
|
||||
- Test: How many messages before compaction?
|
||||
- Baseline: 20-40 messages (file-heavy work)
|
||||
- Expected: 30-60 messages (better context management)
|
||||
|
||||

|
||||
|
||||
## Risks & Mitigations
|
||||
|
||||
### Risk 1: API Memory Not Yet Active
|
||||
**Impact**: Script behavior unchanged, no benefit
|
||||
**Mitigation**: Script still works exactly as before (backward compatible)
|
||||
|
||||
### Risk 2: API Memory Incomplete
|
||||
**Impact**: Some features work, others don't
|
||||
**Mitigation**: Fallback to file-based system for missing features
|
||||
|
||||
### Risk 3: API Memory Overhead
|
||||
**Impact**: Querying Memory adds latency
|
||||
**Mitigation**: Timeout on Memory queries, fall back to files
|
||||
|
||||
### Risk 4: Breaking Changes
|
||||
**Impact**: Script fails in new environment
|
||||
**Mitigation**: Extensive testing, graceful degradation
|
||||
|
||||

|
||||
|
||||
## Recommendations for Next Session
|
||||
|
||||
### Immediate Actions
|
||||
1. ✅ **Run session-init.js as-is** - Don't modify yet
|
||||
2. ✅ **Observe API Memory behavior** - Note what changes
|
||||
3. ✅ **Document findings** - What works, what doesn't
|
||||
4. ⚠️ **Don't optimize prematurely** - Understand system first
|
||||
|
||||
### After Understanding API Memory
|
||||
1. Implement Phase 1 detection (30 mins)
|
||||
2. Test with file-heavy operations
|
||||
3. Measure session length improvement
|
||||
4. Report findings to inform Phase 2
|
||||
|
||||
### Long-Term
|
||||
- Phase 2 optimization (2 hours) - Conditional file reads
|
||||
- Phase 3 instrumentation (1 hour) - Metrics collection
|
||||
- Phase 4 enhancement (4 hours) - Full Memory integration (see inst_019)
|
||||
|
||||
---
|
||||
|
||||
## Current Status
|
||||
|
||||
**session-init.js**: ✅ **READY FOR API MEMORY**
|
