feat(routing): implement WorkflowSpec and CronWorkflowSpec types

Browse Source 
Task 1.1 COMPLETE ✅

Core type definitions for routing workflows:
- WorkflowSpec: One-time workflow specification
- CronWorkflowSpec: Scheduled workflow specification
- State: Individual step in workflow (Task/Pass/Fail)
- RetryPolicy: Retry configuration with backoff
- CatchClause: Error handling
- ExecutionContext: Tracks state during execution
- ActivityMetadata: Describes activity capabilities
- Supporting types: PollParams, Heartbeat, Result

All types support JSON marshaling/unmarshaling.
8 unit tests covering complex scenarios (9/9 PASS).

Acceptance criteria met:
✅ All types compile without errors
✅ JSON marshaling/unmarshaling works correctly
✅ Unit tests pass (complex workflow examples)
✅ Ready for next phase (Knowledge Base)

Effort: 2 hours

"Analyze repo for security and quality"
or
"Scan all repos daily at 2 AM"
↓
[llm-router Activity] - Intelligent Workflow Generator
├─ Reads: ActivityKnowledgeBase.json (metadata about activities)
├─ Uses LLM to understand intent
├─ Selects activities: Clone → Analyze → SecurityScan → Combine → Notify
├─ Orders by dependencies
├─ Decides timeout for each (from knowledge base)
├─ Decides retry policy (from isFlaky flag)
├─ Chains parameters (JSONPath: ${Clone.output.path})
├─ Detects if scheduled (cron)
└─ Generates: WorkflowSpec or CronWorkflowSpec (JSON)
↓
[RoutingWorkflow] - Generic Executor
├─ Takes JSON spec from llm-router
├─ Executes states in order
├─ Respects timeout/retry for each activity
├─ Handles errors with catch blocks
└─ Returns results
↓
[Temporal] - Distributed Workflow Engine
├─ For one-time: Executes immediately
├─ For cron: Schedules and runs on schedule
├─ Provides durability (replay guarantee)
├─ Tracks execution history
└─ Handles retries automatically
↓
[Results] - Final Output
├─ Execution history
├─ Step-by-step results
├─ Performance metrics
└─ Status updates

# Cron Jobs in Poimen Workflows
## Quick Summary
**llm-router** detects if user is asking for scheduled/recurring work and generates either:
- **WorkflowSpec** (one-time execution)
- **CronWorkflowSpec** (scheduled execution)
---
## CRON EXAMPLES
### Example 1: Daily Security Scan
**User says**: "Run security scan on all repos every day at 2 AM"
**llm-router detects**:
- is_scheduled: true
- schedule: "0 2 * * *" (2 AM every day)
- activities_needed: [Clone, SecurityScan, SendAlert]
**llm-router generates**:
```json
{
"type": "CronWorkflow",
"name": "daily-security-scan",
"schedule": "0 2 * * *",
"timezone": "UTC",
"input": {"repos": [...]},
"states": [
{"name": "Clone", "type": "Task", "resource": "CloneRepoActivity", ...},
{"name": "SecurityScan", "type": "Task", "resource": "SecurityScanActivity", ...},
{"name": "SendAlert", "type": "Task", "resource": "SendNotificationActivity", ...}
]
}
```
**Temporal** executes this:
- At 2 AM UTC every day
- Runs RoutingWorkflow with this spec
- Each run is independent (tracks execution history)
---
### Example 2: Hourly Health Check
**User says**: "Check API health every hour"
**llm-router generates**:
```json
{
"type": "CronWorkflow",
"schedule": "0 * * * *",
"timezone": "UTC",
"states": [
{"name": "HealthCheck", "type": "Task", "resource": "HealthCheckActivity", ...},
{"name": "RecordMetrics", "type": "Task", "resource": "RecordMetricsActivity", ...}
]
}
```
**Execution**: Every hour, automatically
---
### Example 3: Weekly Performance Baseline
**User says**: "Compare performance with baseline every Sunday at 3 AM"
**llm-router generates**:
```json
{
"type": "CronWorkflow",
"schedule": "0 3 * * 0",
"timezone": "America/New_York",
"states": [...]
}
```
**Execution**: Every Sunday at 3 AM in New York timezone
---
## CRON SCHEDULE SYNTAX
```
┌───────────── minute (0 - 59)
│ ┌───────────── hour (0 - 23)
│ │ ┌───────────── day of month (1 - 31)
│ │ │ ┌───────────── month (1 - 12)
│ │ │ │ ┌───────────── day of week (0 - 6, 0 = Sunday)
│ │ │ │ │
│ │ │ │ │
* * * * *
Common Examples:
0 2 * * * → Every day at 2:00 AM
0 */6 * * * → Every 6 hours
0 9 * * 1-5 → Weekdays at 9 AM (Mon-Fri)
0 0 1 * * → First day of month at midnight
0 0 * * 0 → Every Sunday at midnight
*/15 * * * * → Every 15 minutes
30 2 * * 0 → Every Sunday at 2:30 AM
```
---
## EXECUTION TRACKING
Temporal automatically tracks all cron executions:
```
Workflow: daily-security-scan
Run 1: 2025-02-01 02:00:00 UTC → COMPLETED (5m 32s)
Run 2: 2025-02-02 02:00:00 UTC → COMPLETED (4m 58s)
Run 3: 2025-02-03 02:00:00 UTC → FAILED (timeout in SecurityScan)
Run 4: 2025-02-04 02:00:00 UTC → COMPLETED (6m 15s)
Run 5: 2025-02-05 02:00:00 UTC → COMPLETED (5m 01s)
```
Retrieve with:
```bash
temporal workflow list --query "ExecutionStatus='Completed' AND WorkflowType='RoutingWorkflow'"
temporal workflow describe --workflow-id daily-security-scan
```
---
## HOW llm-router DETECTS CRON
LLM looks for keywords in user message:
```
"every day at 2 AM" → "0 2 * * *"
"every 6 hours" → "0 */6 * * *"
"daily" → "0 0 * * *"
"weekly" → "0 0 * * 0" (Sunday)
"every Monday" → "0 0 * * 1"
"every 15 minutes" → "*/15 * * * *"
"weekdays at 9 AM" → "0 9 * * 1-5"
"first of month" → "0 0 1 * *"
"midnight" → "0 0"
```
---
## DIFFERENCES: One-Time vs Cron
| Aspect | One-Time | Cron |
|--------|----------|------|
| **Type** | WorkflowSpec | CronWorkflowSpec |
| **Triggered by** | API call, CLI | Schedule |
| **Execution** | Runs once, returns immediately | Runs on schedule, indefinitely |
| **Input** | Varies per call | Fixed for all runs |
| **History** | Single execution | Multiple executions tracked |
| **Cancellation** | Can't cancel | Can stop/restart cron |
| **Use Case** | Ad-hoc analysis | Background monitoring |
---
## API ENDPOINTS (Proposed)
### Submit Cron Workflow
```bash
POST /api/v1/cron/workflows
{
"type": "CronWorkflow",
"schedule": "0 2 * * *",

"next_run": "2025-02-02 02:00:00 UTC",
"created": "2025-02-01 15:30:00 UTC"
}
```
### Get Cron Status
```bash
GET /api/v1/cron/workflows/daily-security-scan/status

{
"workflow_id": "daily-security-scan",
"schedule": "0 2 * * *",
"is_active": true,
"last_run": {
"time": "2025-02-01 02:00:00 UTC",
"status": "COMPLETED",
"duration": "5m 32s"
},
"next_run": "2025-02-02 02:00:00 UTC",

"schedule": "0 * * * *",
"is_active": true,
"created": "2025-02-01 16:00:00 UTC"
}
]
}
```
### Cancel Cron Workflow
```bash
DELETE /api/v1/cron/workflows/daily-security-scan
Response:
{
"status": "cancelled",
"workflow_id": "daily-security-scan",
"cancelled_at": "2025-02-01 16:30:00 UTC"
}
```
---
## SUMMARY
✅ **llm-router handles both**:
- One-time workflows (instant execution)
- Cron workflows (scheduled, recurring)
✅ **Same RoutingWorkflow executor** for both
✅ **Temporal manages scheduling** (native support)
✅ **Full execution history** tracked
This completes the architecture! 🎉

# Poimen Service Integration & Dynamic Workflows — MASTER REVIEW DOCUMENT
**Status**: Ready for Approval
**Version**: 1.0
**Date**: 2025-01-31
**Duration**: 52-58 hours (4 weeks)
---
## EXECUTIVE SUMMARY (5 MINUTES)
### Problem
Current workflows are **hardcoded in Go**. Changing activity sequences requires:
- Code modification
- Recompilation
- K8s deployment
- Pod restart
- **Total: 5-10 minutes**
### Solution
New **RoutingWorkflow** reads JSON WorkflowSpec and executes dynamically:
- **Three entry points**: CLI + HTTP API + Legacy CLI (backward compatible)
- **Three patterns**: Sequential, Await-Task-Complete (KMSvc queue), Retry with error handling
- **JSONPath parameters**: `${step1.output.path}` instead of hardcoded values
- **Result**: Workflow changes in **seconds** (API call only)
### Impact
✅ Instant changes | ✅ Three interfaces | ✅ Full compatibility | ❌ +KMSvc complexity
---
## PART 1: THE THREE PATTERNS
### Pattern 1: Sequential (A → B → C)
Activities execute in sequence. Each step passes output to next via JSONPath.
```json
{
"activities": [
{
"name": "Clone",
"resource": "CloneRepoActivity",
"parameters": {"repo": "${input.repo}"},
"timeout": "5m",
"next": "Analyze"
},
{
"name": "Analyze",
"resource": "AnalyzeCodeActivity",
"parameters": {"path": "${Clone.output.path}"},
"timeout": "10m",
"next": "Judge"
},
{
"name": "Judge",
"resource": "JudgeActivity",
"parameters": {"code": "${Analyze.output.code}"},
"timeout": "5m",
"end": true
}
]
}
```
**Execution Flow**:
```
Clone ──(output: {path: /tmp/repo})──> Analyze ──(output: {code: ...})──> Judge ──(final result)
```
**Use Case**: Code review pipeline (clone → analyze → judge)
---
### Pattern 2: Await-Task-Complete (Launch → Poll Queue → Process)
Launch long-running job, poll KMSvc queue for result with correlation ID matching, then proceed.
```json
{
"name": "LaunchJob",
"type": "awaitTaskComplete",
"resource": "LaunchJobActivity",
"parameters": {"job_id": "job-123"},
"queue": "job-completions",
"correlation_key": "${LaunchJob.output.correlation_id}",
"timeout": "5m",
"next": "ProcessResult"
}
```
**Execution Flow**:
```
LaunchJobActivity ──(returns {correlation_id: "xyz"})──> Poll Queue "job-completions"
↓
[External system completes job]
[Publishes {correlation_id: "xyz", result: ...}]
↓
[Workflow receives message]
[Proceeds to ProcessResult]
```
**Note**: Pattern 2 type name is `awaitTaskComplete` (awaits task completion via queue)
**Use Case**: Long-running batch jobs (model training, data processing)
---
### Pattern 3: Retry with Error Handling (Retry N times with backoff)
Activity retries N times with exponential backoff. On failure, jumps to catch block.
```json
{
"name": "Generate",
"resource": "ImplementerActivity",
"parameters": {"task": "${input.task}"},
"timeout": "30m",
"retry": {
"maxAttempts": 3,
"backoffRate": 2.0,
"initialInterval": "1s"
},
"catch": [
{"errorEquals": ["Timeout"], "next": "HandleTimeout"}
],
"next": "Verify"
}
```
**Execution Flow**:
```
Generate (attempt 1) ──TIMEOUT──> [Wait 1s]
Generate (attempt 2) ──TIMEOUT──> [Wait 2s]
Generate (attempt 3) ──TIMEOUT──> [Wait 4s]
Max retries exceeded ──> Jump to HandleTimeout
```
**Use Case**: Code generation (retry on timeout, handle gracefully)
---
## PART 2: THE THREE ENTRY POINTS
### Entry Point 1: CLI (New Command-Line)
```bash
# Submit workflow from JSON file
$ poimen-cli submit workflow.json
Workflow submitted: wf-abc123
Poll status: poimen-cli status wf-abc123
# Submit and wait for results
$ poimen-cli submit workflow.json --wait
Waiting for workflow to complete...
✅ Workflow completed
Output: {...}
# Execute template immediately (sync, no polling)
$ poimen-cli execute template code-review-v1 --input-file input.json
Executing template...
Step 1/3: Clone ... OK (45s)
Step 2/3: Analyze ... OK (120s)
Step 3/3: Judge ... OK (30s)
✅ COMPLETED
Output: {...}
# Check status later
$ poimen-cli status wf-abc123
Workflow ID: wf-abc123
Status: COMPLETED

}'
```
**Response** (immediate):
```json
{
"status": "COMPLETED",
"results": {...},
"final_output": {...}
}
```

## PART 4: BEFORE vs AFTER
### Before (Hardcoded Workflows)
```bash
# To change activity sequence:
1. Modify Go code (OrchestratorWorkflow in statemachine/)
2. Compile: go build ./cmd/worker
3. Push docker image
4. Deploy to K8s: kubectl set image deployment/poimen-worker
5. Wait for rollout
Time: 5-10 minutes
```
**Workflow definition**:
```go
// Hard to change, tight coupling to specific sequence
if err := workflow.ExecuteActivity(ctx, "CloneRepoActivity", params).Get(ctx, nil); err != nil {
return err
}
if err := workflow.ExecuteActivity(ctx, "PlanningActivity", params2).Get(ctx, nil); err != nil {
return err
}
// ... more activities hardcoded
```
---
### After (Dynamic Workflows)
```bash
# To change activity sequence:
1. Edit workflow.json (define sequence)
2. Call API or CLI
3. Done
Time: Seconds
```
**Workflow definition**:
```json
{
"activities": [

## PART 5: IMPLEMENTATION PHASES
### Phase 1: Routing Engine (Week 1) — 20-22 Hours
**Goal**: Core RoutingWorkflow that executes JSON sequences dynamically
**Files to Create**:
```
internal/routing/
├─ types.go (2h) - WorkflowSpec, ActivityStep
├─ jsonpath_evaluator.go (3h) - ${step1.output.path} resolution
├─ execution_context.go (2h) - State tracking (vars, step results)
├─ activity_registry.go (2h) - Activity name → function mapping
├─ kmsvc_client.go (2-3h)- KMSvc queue polling (awaitTaskComplete)
└─ *_test.go (tests)
statemachine/
├─ routing_workflow.go (4-5h)- ⭐ Main workflow logic
└─ routing_workflow_test.go (2h) - Tests
cmd/worker/main.go: Register RoutingWorkflow (1h)
```
**Deliverable**: RoutingWorkflow executes activity sequences with:
- ✅ Sequential execution (A → B → C)
- ✅ Await-Task-Complete pattern (KMSvc queue polling)
- ✅ Retry with exponential backoff
- ✅ Error catch blocks
- ✅ JSONPath parameter resolution
**Risk**: Low-Medium (KMSvc queue polling adds complexity)
---
### Phase 2: API Server (Week 2) — 12-14 Hours
**Goal**: HTTP endpoints for workflow submission and status polling
**Files to Create**:
```
cmd/api-server/
├─ main.go (2h) - Server bootstrap
├─ handlers.go (4h) - Routes: /workflows, /execute, status
├─ validation.go (2h) - Validate WorkflowSpec
├─ template_loader.go (2-3h)- Load predefined templates
└─ *_test.go (2h) - Tests
```
**Deliverable**:
- `POST /api/v1/workflows` — Submit workflow (async)
- `GET /api/v1/workflows/{id}/status` — Check status
- `POST /api/v1/execute` — Execute template (sync)
**Risk**: Low (isolated, no breaking changes)
---
### Phase 3: CLI (Week 2) — 8-10 Hours
**Goal**: Command-line interface for workflow submission
**Files to Create**:
```
cmd/cli/
├─ main.go (2h) - Entry point, command routing
└─ commands/
├─ submit.go (2h) - poimen-cli submit workflow.json
├─ status.go (2h) - poimen-cli status wf-id
├─ template.go (1h) - poimen-cli template list/show
├─ execute.go (1h) - poimen-cli execute template
└─ history.go (1h) - poimen-cli history wf-id
```
**Deliverable**:
- `poimen-cli submit workflow.json [--wait] [--watch]`
- `poimen-cli status wf-id [--wait]`
- `poimen-cli execute template name --input-file input.json`
- `poimen-cli template list/show`
**Risk**: Low
---
### Phase 4: Kubernetes Integration (Week 3) — 5 Hours
**Goal**: Deploy api-server to K8s, expose via ingress
**Files to Create**:
```
k8s/
├─ api-server-deployment.yaml (2h) - 2 replicas, Temporal connection
├─ api-server-service.yaml (1h) - Port 8080
└─ api-server-networkpolicy.yaml(1h) - Allow ingress traffic
homelab-frontend/k8s/
└─ gateway-routes.yaml (1h) - Route /api/v1/workflows to api-server
```
**Deliverable**: API exposed at `https://api.riotpiao.com/api/v1/workflows`
**Risk**: Medium (network policy changes)
---
### Phase 5: Documentation (Week 4) — 7 Hours
**Files to Create**:
```
docs/
├─ API.md (2h) - Complete API reference
├─ CLI.md (2h) - CLI commands + examples
├─ TEMPLATES.md (1h) - How to create/manage templates
├─ MIGRATION.md (1h) - Migration from cmd/starter
└─ examples/
├─ sequential-workflow.json
├─ retry-workflow.json
└─ template-execute.json
```
**Deliverable**: Complete documentation with working examples
**Risk**: Low
---

---
## PART 6: CRITICAL KMSVC QUESTIONS
These answers **block implementation** of Phase 1:
### Q1: What is KMSvc?
- Is it Kafka? Redis? AWS SQS? Custom system?
- What Go client library should we use?
- Example: `github.com/segmentio/kafka-go`?
### Q2: Message Format
- Is it JSON?
- What fields are required? (e.g., `correlation_id`, `result`, `status`?)
- Example:
```json
{
"correlation_id": "xyz123",
"status": "completed",
"result": {...}
}
```
### Q3: Correlation ID Management
- Who generates the correlation_id? (LaunchJobActivity? Or RoutingWorkflow?)
- Is it returned in LaunchJobActivity output?
- Example: LaunchJobActivity returns:
```json
{
"correlation_id": "abc123-generated-by-activity",
"job_id": "job-123"
}
```
### Q4: Queue Polling Strategy
- Active polling loop (pull messages every N seconds)? OR
- Temporal Signal (push-based, external system sends signal to workflow)?
- If polling: What interval? (1s, 5s, 10s?)
### Q5: Message Timeout Behavior
- If no message arrives within timeout (e.g., 5m), what happens?
- Option A: Jump to catch block (error handler)
- Option B: Fail entire workflow
- Option C: Infinite wait (only human intervention can stop)
### Q6: Consumer Group Strategy
- Single shared consumer (all workflows share one connection)?
- Per-workflow consumer (each workflow gets own connection)?
- Dead-letter queue for unmatched messages?
---
## PART 7: KEY DESIGN DECISIONS
### Decision 1: Three Patterns (Sequential, Await-Task-Complete, Retry)
**Rationale**: Covers 90% of use cases. Retry critical for production. Await-Task-Complete enables long-running jobs.
**Alternative Rejected**: Just Sequential (too limited)
### Decision 2: KMSvc Queue for Await-Task-Complete Pattern
**Rationale**: Decouples external systems from Temporal. External systems only need queue client, not Temporal SDK.
**Alternative Rejected**: Temporal callback/signal (tight coupling)
### Decision 3: JSONPath for Parameters
**Rationale**: Standard notation (AWS Step Functions, Kubernetes). Supports nested refs and arrays.
**Alternative Rejected**: Go templating (overkill, security risks)
### Decision 4: RoutingWorkflow (not Activity)
**Rationale**: Workflows can call activities with retries. Durable execution + replay guarantee.
**Alternative Rejected**: RoutingActivity (can't call other activities, no retries)
### Decision 5: Static Activity Registry
**Rationale**: Type-safe, simpler. Worker pod must compile all activities anyway.
**Alternative Rejected**: Dynamic registration (complex, unsafe)
### Decision 6: Keep cmd/starter Forever
**Rationale**: No need to break existing deployments. Let customers choose.
**Alternative Rejected**: Deprecate (breaking change)
### Decision 7: Shared api-server (2 replicas)
**Rationale**: Simpler, resource-efficient, easier to scale.
**Alternative Rejected**: Per-namespace servers (overkill)

## PART 8: RISKS & MITIGATIONS
| Risk | Severity | Mitigation |
|------|----------|-----------|
| JSONPath evaluation bugs | Medium | Unit tests (>90% coverage), property-based testing |
| **KMSvc queue reliability** | **High** | Dead-letter queue, timeouts, persistence checks |
| **Correlation ID mismatch** | **Medium** | Strict matching, schema validation, detailed logging |
| **Consumer group conflicts** | **Medium** | Clear strategy, rebalancing, message redelivery |
| Activity registry mismatch | Low | Validate at spec submission time |
| Temporal network issues | Low | Retry + timeout in api-server |
| Cache staleness (api-server) | Low | 24h TTL, event-driven invalidation |
| Performance regression | Low | Measure baseline: target <200ms submit, <100ms poll |
**Total Risk Score**: Medium-High (up from Low-Medium due to KMSvc)
---
## PART 9: SUCCESS CRITERIA

## 💡 TIPS FOR SUCCESS
1. **Start with types** (Task 1.1)
- Everything depends on these
- Make them flexible
- Good JSON schema helps
2. **Knowledge base is critical** (Task 1.2)
- LLM decisions are based on this
- Make it comprehensive
- Document each activity well
3. **Test llm-router early** (Task 2.3)
- This is highest risk
- Test with real LLM calls
- Validate output quality
4. **RoutingWorkflow is the heart** (Task 3.4)
- Make sure state machine is solid
- Test error paths thoroughly
- Performance matters
5. **API/CLI can be simple** (Tasks 4.x)
- Just thin wrappers
- Focus on DX (developer experience)
- Good error messages
6. **Test everything** (Phase 5)
- Unit tests catch bugs early
- Integration tests find edge cases
- E2E tests validate full flow
- Load tests validate performance
