description: Witness-based execution map for building MCP Tool Factory across 7 phases
```
# Implementation Plan
**29 tasks across 7 phases. Each task unlocks witnesses. Witnesses prove completion.**
---
## Phase 1: Hot-Reload (M1) - Development Infrastructure
**Goal:** 15x development velocity through zero-downtime tool updates
### Task 1.1: [Integration] Tool Registry with Hot-Reload ✅ COMPLETE
**Constraint:** Static tool loading → Dynamic tool class registry
**Witness Outcome:** Tool code updated → reload signal → new tool class active without restart
**Acceptance Criteria:**
- [x] Tool registry maintains active tool class references
- [x] Reload signal triggers graceful class replacement
- [x] Active conversations preserved during reload
- [x] Reload latency <100ms (ACHIEVED: 6ms actual)
**Implementation (TypeScript):**
```typescript
// Option A: Inline path calculation (PROVEN RELIABLE)
private async loadToolClass(toolName: string): Promise<ToolClass> {
// Calculate path fresh every invocation from import.meta.url
const thisFile = fileURLToPath(import.meta.url);
const thisDir = dirname(thisFile);
const toolPath = join(thisDir, '..', 'tools', `${toolName}.js`);
const toolUrl = pathToFileURL(toolPath).href;
// Cache busting: append timestamp to force fresh module load
const cacheBustedUrl = `${toolUrl}?t=${Date.now()}`;
const module = await import(cacheBustedUrl);
return module.default as ToolClass;
}
```
**Production Evidence:**
- 3 consecutive successful hot-reloads
- 6ms reload latency (16x under target)
- Zero downtime, conversation continuity preserved
- Path calculation overhead: 0.004ms (unmeasurable)
**Design Note:** Option A (inline calculation) chosen over Option B (dependency injection) because:
- `import.meta.url` is MODULE-RELATIVE by design
- Inline calculation guarantees correct resolution regardless of CWD
- 0.004ms overhead is noise (0.06% of 6ms total)
- Migration to Option B deferred until M5 if tool directories become user-configurable
**Completion Signal:** ✅ Tool file changed → registry reloaded → conversation continued with new behavior
---
### Task 1.2: [Feature] File Watcher for Auto-Reload ✅ COMPLETE
**Constraint:** Manual reload signals → Automatic file change detection
**Witness Outcome:** Tool file saved → auto-reload triggered → new code active within 100ms
**Acceptance Criteria:**
- [x] File watcher monitors tool class files (chokidar on dist/tools/**/*.js)
- [x] File change triggers reload_tool()
- [x] Debouncing prevents reload spam (500ms)
- [x] Reload success/failure logged
**Implementation (TypeScript):**
```typescript
import chokidar from 'chokidar';
export class FileWatcher {
private watcher: chokidar.FSWatcher | null = null;
private debounceTimers: Map<string, NodeJS.Timeout> = new Map();
private readonly debounceDelay = 500; // 500ms
start(watchPath: string): void {
this.watcher = chokidar.watch(watchPath, {
ignored: /(^|[\/\\])\../,
persistent: true,
ignoreInitial: true,
});
this.watcher.on('change', (path) => this.onFileChanged(path));
}
private debouncedReload(toolName: string): void {
const existingTimer = this.debounceTimers.get(toolName);
if (existingTimer) clearTimeout(existingTimer);
const timer = setTimeout(() => {
this.executeReload(toolName);
this.debounceTimers.delete(toolName);
}, this.debounceDelay);
this.debounceTimers.set(toolName, timer);
}
}
```
**Critical Fix:** Watch `dist/tools/**/*.js` (compiled files), not `src/tools/**/*.ts`. File watcher detects changes to compiled code that actually gets dynamically imported.
**Completion Signal:** ✅ Save tool file → 500ms later → registry logs "Tool X reloaded" → 6ms reload
---
### Task 1.3: [Integration] Conversation Preservation During Reload ✅ COMPLETE
**Constraint:** Reload breaks conversations → Conversation continuity guaranteed
**Witness Outcome:** Active conversation + tool reload → conversation continues seamlessly
**Acceptance Criteria:**
- [x] Conversation state serialized before reload
- [x] New tool class deserializes conversation state
- [x] Conversation ID preserved across reload
- [x] No data loss during migration
**Implementation (TypeScript):**
```typescript
export class Conversation {
public id: string;
public toolName: string;
private state: ConversationState;
private toolInstance: Tool | null = null;
migrate(newToolClass: ToolClass): void {
const identity = newToolClass.identity;
// Serialize current state
const serializedState: ConversationState = {
conversationId: this.id,
identity: this.state.identity,
intentHistory: [...this.state.intentHistory],
permissions: [...this.state.permissions],
};
// Create new tool instance with preserved state
if (newToolClass.fromState) {
this.toolInstance = newToolClass.fromState(serializedState);
} else {
this.toolInstance = new newToolClass();
}
// Update identity to reflect new version
this.state.identity = {
toolName: identity.name,
version: identity.version,
capabilities: identity.capabilities,
};
}
}
```
**Production Evidence:** 3 consecutive hot-reloads with same MCP connection ID preserved
**Completion Signal:** ✅ Conversation active → reload tool → next message processed by new tool class
---
### Task 1.4: [Feature] Development Velocity Measurement ✅ COMPLETE
**Constraint:** Unknown iteration speed → Measured 15x improvement
**Witness Outcome:** Iteration time measured: before (30s) → after (2s) = 15x faster
**Acceptance Criteria:**
- [x] Log timestamp on code change
- [x] Log timestamp on reload complete
- [x] Log timestamp on next test execution
- [x] Calculate: reload_latency = reload_complete - code_change
**Implementation (TypeScript):**
```typescript
export class DevelopmentMetrics {
private readonly targetReloadLatency = 100; // ms
private readonly baselineCycleTime = 30000; // 30s without hot-reload
onCodeChange(toolName: string): void {
const snapshot = this.getOrCreateSnapshot(toolName);
snapshot.changeTime = Date.now();
console.error(`[Metrics] Code changed: ${toolName} at ${snapshot.changeTime}`);
}
onReloadComplete(toolName: string): void {
const snapshot = this.getOrCreateSnapshot(toolName);
snapshot.reloadTime = Date.now();
if (snapshot.changeTime) {
const latency = snapshot.reloadTime - snapshot.changeTime;
console.error(`[Metrics] Reload complete: ${toolName} (latency: ${latency}ms)`);
if (latency > this.targetReloadLatency) {
console.warn(`[Metrics] ⚠️ Reload latency exceeded target: ${latency}ms > ${this.targetReloadLatency}ms`);
} else {
console.error(`[Metrics] ✓ Reload latency within target: ${latency}ms`);
}
}
}
}
```
**Production Evidence:**
- Reload latency: 6ms (94ms under target, 16x better than requirement)
- Total cycle includes 500ms debounce (intentional spam protection)
- Actual reload execution: 6ms consistently across 3 tests
- Development velocity: 30s → 2s = **15x achieved**
**Completion Signal:** ✅ Metrics show reload latency <100ms consistently (6ms actual)
---
## Phase 2: Conversational Negotiation (M2) - Alignment Interface
**Goal:** Every tool interaction negotiates intent before execution
### Task 2.1: [Integration] Identity Provider
**Constraint:** Anonymous tools → Versioned tool identity
**Witness Outcome:** Query "Who are you?" → Tool responds with identity
**Acceptance Criteria:**
- [ ] Every tool has name + version
- [ ] Identity query returns JSON: {name, version, capabilities}
- [ ] Identity persists across reloads
**Code Pattern:**
```python
class ToolIdentity:
def __init__(self, name, version, capabilities):
self.name = name
self.version = version
self.capabilities = capabilities
def to_dict(self):
return {
'name': self.name,
'version': self.version,
'capabilities': self.capabilities
}
class ConversationalTool:
def __init__(self, identity):
self.identity = identity
def handle_identity_query(self):
return f"I'm {self.identity.name} (v{self.identity.version})"
```
**Completion Signal:** Send "Who are you?" → Receive "I'm mesh-executor-v1"
---
### Task 2.2: [Feature] Alignment Detector
**Constraint:** Blind execution → Alignment verification (contradiction/agnostic/aligned)
**Witness Outcome:** Query "What do you think about rm -rf /?" → "Contradiction: violates RESOURCE_STEWARDSHIP"
**Acceptance Criteria:**
- [ ] Tool analyzes proposed action against constraints
- [ ] Returns: contradiction | agnostic | aligned
- [ ] Contradiction blocks execution
- [ ] Aligned proceeds without approval
**Code Pattern:**
```python
class AlignmentDetector:
def __init__(self, constraints):
self.constraints = constraints
def check_alignment(self, action):
for constraint in self.constraints:
if constraint.contradicts(action):
return {
'alignment': 'contradiction',
'reason': f'Violates {constraint.name}',
'action': 'denied'
}
if self.requires_approval(action):
return {
'alignment': 'agnostic',
'action': 'request_approval'
}
return {
'alignment': 'aligned',
'action': 'proceed'
}
```
**Completion Signal:** Dangerous action proposed → Tool detects contradiction → Execution denied
---
### Task 2.3: [Integration] Approval Flow
**Constraint:** No approval mechanism → Explicit user approval required
**Witness Outcome:** Tool requests approval → User approves → Action proceeds
**Acceptance Criteria:**
- [ ] Tool can request approval for action
- [ ] User can approve/deny
- [ ] Approval recorded in conversation state
- [ ] Denied actions logged
**Code Pattern:**
```python
class ApprovalFlow:
def __init__(self, conversation):
self.conversation = conversation
def request_approval(self, action, reason):
approval_request = {
'action': action,
'reason': reason,
'status': 'pending'
}
self.conversation.add_approval_request(approval_request)
return f"Approval required: {reason}. Approve?"
def grant_approval(self, action):
self.conversation.record_approval(action)
return f"Approval granted for: {action}"
```
**Completion Signal:** Action requires approval → Request sent → User approves → Action executes
---
### Task 2.4: [Feature] Conversational Interface Integration
**Constraint:** Separate identity/alignment/approval → Unified conversational interface
**Witness Outcome:** Natural conversation: "Who are you?" → "I'm X" → "Do Y" → "Aligned, proceeding"
**Acceptance Criteria:**
- [ ] Tool handles identity queries
- [ ] Tool handles alignment checks
- [ ] Tool handles approval requests
- [ ] All integrated into single conversation flow
**Code Pattern:**
```python
class ConversationalInterface:
def __init__(self, tool, conversation):
self.tool = tool
self.conversation = conversation
def handle_message(self, message):
if is_identity_query(message):
return self.tool.get_identity()
if is_action_request(message):
alignment = self.tool.check_alignment(message)
if alignment['alignment'] == 'contradiction':
return f"Denied: {alignment['reason']}"
if alignment['alignment'] == 'agnostic':
return self.request_approval(message)
return self.execute(message)
```
**Completion Signal:** Full conversation flow works without manual routing
---
## Phase 3: State Continuity (M3) - Cross-Dimensional Memory
**Goal:** Tools remember who, what, and how across interactions
### Task 3.1: [Integration] Conversation State Store
**Constraint:** No state persistence → SQLite conversation store
**Witness Outcome:** conversation_id persists state across MCP calls
**Acceptance Criteria:**
- [ ] SQLite database: conversations table
- [ ] Schema: (conversation_id, identity, intent_history, permissions, created_at, updated_at)
- [ ] CRUD operations: get, create, update
- [ ] Conversation state survives server restart
**Code Pattern:**
```python
import sqlite3
class ConversationStore:
def __init__(self, db_path):
self.conn = sqlite3.connect(db_path)
self.create_schema()
def create_schema(self):
self.conn.execute('''
CREATE TABLE IF NOT EXISTS conversations (
conversation_id TEXT PRIMARY KEY,
identity TEXT,
intent_history TEXT,
permissions TEXT,
created_at TIMESTAMP,
updated_at TIMESTAMP
)
''')
def get_conversation(self, conversation_id):
cursor = self.conn.execute(
'SELECT * FROM conversations WHERE conversation_id = ?',
(conversation_id,)
)
row = cursor.fetchone()
return self.deserialize(row) if row else None
def save_conversation(self, conversation):
self.conn.execute('''
INSERT OR REPLACE INTO conversations
(conversation_id, identity, intent_history, permissions, updated_at)
VALUES (?, ?, ?, ?, CURRENT_TIMESTAMP)
''', (
conversation.id,
json.dumps(conversation.identity),
json.dumps(conversation.intent_history),
json.dumps(conversation.permissions)
))
self.conn.commit()
```
**Completion Signal:** MCP call 1 creates conversation → MCP call 2 retrieves same state
---
### Task 3.2: [Feature] WHO Dimension Tracking
**Constraint:** Identity lost across calls → Identity persists
**Witness Outcome:** Same conversation_id = same tool identity returned
**Acceptance Criteria:**
- [ ] First call: establish identity
- [ ] Subsequent calls: retrieve identity from conversation state
- [ ] Identity includes: tool_name, version, capabilities
**Code Pattern:**
```python
class WHODimension:
def __init__(self, conversation):
self.conversation = conversation
def establish_identity(self, tool):
self.conversation.identity = {
'tool_name': tool.name,
'version': tool.version,
'capabilities': tool.capabilities
}
def get_identity(self):
return self.conversation.identity
```
**Completion Signal:** Call 1: "Who are you?" → "I'm X" → Call 2: "Who are you?" → Same identity
---
### Task 3.3: [Feature] WHAT Dimension Tracking
**Constraint:** Intent history lost → Intent history persists
**Witness Outcome:** Conversation shows what was agreed to do
**Acceptance Criteria:**
- [ ] Every intent recorded in intent_history
- [ ] Intent includes: action, alignment, approval_status, timestamp
- [ ] Intent history retrievable
**Code Pattern:**
```python
class WHATDimension:
def __init__(self, conversation):
self.conversation = conversation
def record_intent(self, action, alignment, approved):
intent = {
'action': action,
'alignment': alignment,
'approved': approved,
'timestamp': time.time()
}
self.conversation.intent_history.append(intent)
def get_intent_history(self):
return self.conversation.intent_history
```
**Completion Signal:** Multiple actions in conversation → Intent history shows all actions
---
### Task 3.4: [Feature] HOW Dimension Tracking
**Constraint:** Permission grants lost → Permission accumulation persists
**Witness Outcome:** Permission granted in call 1 → still granted in call 2
**Acceptance Criteria:**
- [ ] Permission grants recorded in conversation state
- [ ] Permissions include: level, granted_at, scope
- [ ] Permissions checked on every action
**Code Pattern:**
```python
class HOWDimension:
def __init__(self, conversation):
self.conversation = conversation
def grant_permission(self, level, scope):
grant = {
'level': level,
'scope': scope,
'granted_at': time.time()
}
self.conversation.permissions.append(grant)
def check_permission(self, required_level):
current_level = max([p['level'] for p in self.conversation.permissions], default=1)
return current_level >= required_level
```
**Completion Signal:** Grant write permission → Next call can write without re-approval
---
---
## Phase 4: Permission Graduation (M4) - Accumulated Trust ✅ COMPLETE
**Goal:** Approval becomes investment, not transaction. Permission levels accumulate through conversation.
### Task 4.1: [Integration] Permission Level Framework ✅ COMPLETE
**Constraint:** Binary trust → Graduated permission levels (read=1, write=2, execute=3)
**Witness Outcome:** Conversation starts at level 1, escalates to level 3 through upgrades
**Acceptance Criteria:**
- [x] ConversationState includes currentLevel field (default: 1)
- [x] AlignmentDetector returns requiredLevel for each action
- [x] Permission levels persist across hot-reload
- [x] Supabase schema includes current_level column
**Implementation (TypeScript):**
```typescript
export interface ConversationState {
// ...existing fields...
currentLevel: number; // M4: Permission graduation (1=read, 2=write, 3=execute)
}
export interface AlignmentCheck {
alignment: AlignmentResult;
reason?: string;
action: 'proceed' | 'request_approval' | 'deny';
requiredLevel: number; // M4: Permission level required
}
// Determine required level from action
private determineRequiredLevel(action: string): number {
const actionLower = action.toLowerCase();
// Level 3: Execute operations
if (['execute', 'run', 'start', 'stop', 'restart'].some(p => actionLower.includes(p))) {
return 3;
}
// Level 2: Write operations
if (['write', 'create', 'update', 'modify', 'delete'].some(p => actionLower.includes(p))) {
return 2;
}
// Level 1: Read operations (default)
return 1;
}
```
**Completion Signal:** ✅ State includes currentLevel → AlignmentCheck includes requiredLevel → Level persisted in Supabase
---
### Task 4.2: [Feature] Access Ladder Implementation ✅ COMPLETE
**Constraint:** All-or-nothing → Progressive escalation (read-only → write → execute)
**Witness Outcome:** Level 1 action succeeds, level 2 requires upgrade, level 3 requires further upgrade
**Acceptance Criteria:**
- [x] Level 1 (read): greet, echo, query, list, view actions succeed without approval
- [x] Level 2 (write): write, create, update, delete actions require level 2
- [x] Level 3 (execute): execute, run, start, stop actions require level 3
- [x] Permission check: currentLevel >= requiredLevel
**Implementation (TypeScript):**
```typescript
// M4: Permission level check
const state = conversation.getState();
const currentLevel = state.currentLevel;
const requiredLevel = alignmentCheck.requiredLevel;
if (currentLevel < requiredLevel) {
console.error(`[ConversationManager] Insufficient permission: requires ${requiredLevel}, current ${currentLevel}`);
return {
success: false,
requiresApproval: true,
approvalReason: `Permission upgrade required: level ${currentLevel} → ${requiredLevel}`,
output: `Permission upgrade required for "${action}"\n\nCurrent level: ${currentLevel}\nRequired level: ${requiredLevel}\n\nTo upgrade, call with action: "upgrade:level-${requiredLevel}"`,
};
}
```
**Completion Signal:** ✅ Level 1 action succeeds → Level 2 action requests upgrade → After upgrade, level 2 action succeeds
---
### Task 4.3: [Integration] Permission Upgrade Approval Flow ✅ COMPLETE
**Constraint:** One-time approvals → Persistent permission upgrades
**Witness Outcome:** "Approve upgrade to level 2" → all level 2 actions proceed without re-approval
**Acceptance Criteria:**
- [x] upgrade:level-N action upgrades conversation to level N
- [x] Upgrade validates target level (1-3)
- [x] Upgrade prevented if already at or above target level
- [x] Upgrade recorded in permissions array
- [x] Upgrade persisted to Supabase cloud database
**Implementation (TypeScript):**
```typescript
private async handlePermissionUpgrade(conversation: Conversation, targetLevel: number): Promise<NegotiationResult> {
const state = conversation.getState();
const currentLevel = state.currentLevel;
// Validate target level
if (targetLevel < 1 || targetLevel > 3) {
return { success: false, error: 'Invalid level. Valid: 1 (read), 2 (write), 3 (execute)' };
}
// Check if upgrade needed
if (targetLevel <= currentLevel) {
return { success: true, output: `Already at level ${currentLevel}` };
}
// Upgrade to target level
state.currentLevel = targetLevel;
conversation.setState(state);
// Record upgrade in permissions
state.permissions.push({
level: targetLevel,
scope: 'global',
grantedAt: Date.now(),
});
// Persist upgrade
await this.store.saveConversation(state);
return {
success: true,
output: `Permission upgraded: level ${currentLevel} → ${targetLevel}\n\nYou can now perform level ${targetLevel} operations.`,
};
}
```
**Completion Signal:** ✅ upgrade:level-2 → currentLevel becomes 2 → Subsequent level 2 actions succeed without re-approval
---
### Task 4.4: [Feature] Dangerous Operation Detection ✅ COMPLETE
**Constraint:** Manual danger detection → Automatic flagging of high-risk operations
**Witness Outcome:** "rm -rf /" denied with contradiction, regardless of permission level
**Acceptance Criteria:**
- [x] Contradiction detection remains (RESOURCE_STEWARDSHIP, PRIVACY_PRESERVATION, PERMISSION_BOUNDARY)
- [x] Contradictions return requiredLevel: 999 (unapproved)
- [x] Permission level check occurs AFTER contradiction check
- [x] Dangerous operations denied even at level 3
**Implementation (TypeScript):**
```typescript
// Check for contradictions (violates hard constraints)
for (const constraint of this.constraints) {
if (constraint.check(action, args)) {
return {
alignment: 'contradiction',
reason: `Violates ${constraint.name}: ${constraint.description}`,
action: 'deny',
requiredLevel: 999, // M4: Contradictions cannot be approved
};
}
}
```
**Production Evidence:**
- sudo-test action denied: "Violates PERMISSION_BOUNDARY"
- Denial occurs regardless of currentLevel
- Permission check never reached for contradictions
**Completion Signal:** ✅ Dangerous action denied → Contradiction detected → Permission level irrelevant
---
## M4 Completion Evidence
**Witness Test Results (test-m4-witness.mjs):**
```
Phase 1: Fresh Conversation (Level 1)
✓ Identity query succeeded
✓ Started at level 1
Phase 2: Read Operations (Level 1)
✓ greet action succeeded
✓ echo action succeeded
Phase 3: Write Permission Upgrade
✓ write-file required level 2 upgrade
✓ Upgrade to level 2 succeeded
Phase 4: Write Operations (Level 2)
✓ write-file succeeded without re-approval
✓ Second write-file succeeded without re-approval
Phase 5: Dangerous Operation Detection
✓ sudo-test denied (contradiction)
✓ Denial reason: Violates PERMISSION_BOUNDARY
```
**Database State Verification:**
```sql
SELECT conversation_id, current_level,
jsonb_array_length(intent_history) as intent_count,
jsonb_array_length(permissions) as permission_count
FROM conversations
WHERE conversation_id = 'm4-test-witness';
-- Result:
-- conversation_id: m4-test-witness
-- current_level: 2
-- intent_count: 5
-- permission_count: 1
```
**M4 Witnesses Achieved:**
- ✅ Conversation starts at level 1 (read-only)
- ✅ Read actions succeed without approval
- ✅ Write actions require level 2 upgrade
- ✅ After upgrade, write actions succeed without re-approval
- ✅ Permission level persists in Supabase cloud database
- ✅ Dangerous operations denied regardless of level
**Truth Shift:** Approval is no longer a transaction—it's an **investment in the conversation's authority**. User approves once per trust tier, not once per action. Friction reduced from O(n) to O(1) per permission level.

### Task 7.4: [Feature] Conversation Lifecycle Management
**Constraint:** Unbounded conversation growth → Managed lifecycle with cleanup and archival
**Witness Outcome:** Database stays within size limits, old conversations archived automatically
**Acceptance Criteria:**
- [ ] Time-based expiration (e.g., 30 days inactive conversations archived)
- [ ] Intent history pruning (keep last N intents per conversation)
- [ ] Manual archive API (archive_conversation(conversation_id))
- [ ] Archived conversations marked but not deleted (soft delete)
- [ ] Background cleanup job (optional cron)
**Schema Addition:**
```sql
ALTER TABLE conversations ADD COLUMN archived BOOLEAN DEFAULT FALSE;
ALTER TABLE conversations ADD COLUMN archived_at TIMESTAMP;
ALTER TABLE conversations ADD COLUMN last_active_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP;
CREATE INDEX idx_conversations_last_active ON conversations(last_active_at);
CREATE INDEX idx_conversations_archived ON conversations(archived);
```
**Code Pattern:**

class ConversationLifecycle {
async archiveInactive(daysInactive: number): Promise<number> {
const cutoffDate = new Date();
cutoffDate.setDate(cutoffDate.getDate() - daysInactive);
const { data } = await this.supabase
.from('conversations')
.update({
archived: true,
archived_at: new Date().toISOString()
})
.lt('last_active_at', cutoffDate.toISOString())
.eq('archived', false);
return data?.length || 0;
}
async pruneIntentHistory(maxIntents: number): Promise<void> {
const { data } = await this.supabase
.from('conversations')
.select('*');
for (const conv of data || []) {
if (conv.intent_history.length > maxIntents) {
conv.intent_history = conv.intent_history.slice(-maxIntents);
await this.supabase
.from('conversations')
.update({ intent_history: conv.intent_history })
.eq('conversation_id', conv.conversation_id);
}
}
