Add orchestration loop phase and workflow execution skill
- Implemented Phase 2: Orchestration Loop for CCW Loop, including executor agent spawning, main loop execution, and iteration management. - Introduced helper functions for action result parsing and user interaction. - Created new skill: workflow-execute, coordinating agent execution for workflow tasks with automatic session discovery, parallel task processing, and status tracking. - Defined execution flow, key design principles, and error handling strategies for the workflow execution process.

# Phase 2: Orchestration Loop
|
||||
|
||||
Spawn single executor agent and run main orchestration loop until completion, pause, or max iterations.
|
||||
|
||||
## Objective
|
||||
|
||||
- Spawn single executor agent with loop context
|
||||
- Run main while loop: wait → parse → dispatch → send_input
|
||||
- Handle terminal conditions (COMPLETED, PAUSED, STOPPED)
|
||||
- Handle interactive mode (WAITING_INPUT → user choice → send_input)
|
||||
- Handle auto mode (next action → send_input)
|
||||
- Update iteration count per cycle
|
||||
- Close agent on exit
|
||||
|
||||
## Execution
|
||||
|
||||
### Step 2.1: Spawn Executor Agent
|
||||
|
||||
```javascript
|
||||
const agent = spawn_agent({
|
||||
message: `
|
||||
## TASK ASSIGNMENT
|
||||
|
||||
### MANDATORY FIRST STEPS (Agent Execute)
|
||||
1. **Read role definition**: ~/.codex/agents/ccw-loop-executor.md (MUST read first)
|
||||
2. Read: .workflow/project-tech.json (if exists)
|
||||
3. Read: .workflow/project-guidelines.json (if exists)
|
||||
|
||||
---
|
||||
|
||||
## LOOP CONTEXT
|
||||
|
||||
- **Loop ID**: ${loopId}
|
||||
- **State File**: .workflow/.loop/${loopId}.json
|
||||
- **Progress Dir**: ${progressDir}
|
||||
- **Mode**: ${mode}
|
||||
|
||||
## CURRENT STATE
|
||||
|
||||
${JSON.stringify(state, null, 2)}
|
||||
|
||||
## TASK DESCRIPTION
|
||||
|
||||
${state.description || task}
|
||||
|
||||
## EXECUTION INSTRUCTIONS
|
||||
|
||||
You are executing CCW Loop orchestrator. Your job:
|
||||
|
||||
1. **Check Control Signals**
|
||||
- Read .workflow/.loop/${loopId}.json
|
||||
- If status === 'paused' -> Output "PAUSED" and stop
|
||||
- If status === 'failed' -> Output "STOPPED" and stop
|
||||
- If status === 'running' -> Continue
|
||||
|
||||
2. **Select Next Action**
|
||||
Based on skill_state:
|
||||
- If not initialized -> Execute INIT
|
||||
- If mode === 'interactive' -> Output MENU and wait for input
|
||||
- If mode === 'auto' -> Auto-select based on state
|
||||
|
||||
3. **Execute Action**
|
||||
- Follow action instructions from ~/.codex/skills/ccw-loop/actions/
|
||||
- Update progress files in ${progressDir}/
|
||||
- Update state in .workflow/.loop/${loopId}.json
|
||||
|
||||
4. **Output Format**
|
||||
\`\`\`
|
||||
ACTION_RESULT:
|
||||
- action: {action_name}
|
||||
- status: success | failed | needs_input
|
||||
- message: {user message}
|
||||
- state_updates: {JSON of skill_state updates}
|
||||
|
||||
NEXT_ACTION_NEEDED: {action_name} | WAITING_INPUT | COMPLETED | PAUSED
|
||||
\`\`\`
|
||||
|
||||
## FIRST ACTION
|
||||
|
||||
${!state.skill_state ? 'Execute: INIT' : mode === 'auto' ? 'Auto-select next action' : 'Show MENU'}
|
||||
`
|
||||
})
|
||||
```
|
||||
|
||||
### Step 2.2: Main Orchestration Loop
|
||||
|
||||
```javascript
|
||||
let iteration = state.current_iteration || 0
|
||||
const maxIterations = state.max_iterations || 10
|
||||
let continueLoop = true
|
||||
|
||||
while (continueLoop && iteration < maxIterations) {
|
||||
iteration++
|
||||
|
||||
// Wait for agent output
|
||||
const result = wait({ ids: [agent], timeout_ms: 600000 })
|
||||
|
||||
// Handle timeout
|
||||
if (result.timed_out) {
|
||||
console.log('Agent timeout, requesting convergence...')
|
||||
send_input({
|
||||
id: agent,
|
||||
message: `
|
||||
## TIMEOUT NOTIFICATION
|
||||
|
||||
Execution timeout reached. Please:
|
||||
1. Output current progress
|
||||
2. Save any pending state updates
|
||||
3. Return ACTION_RESULT with current status
|
||||
`
|
||||
})
|
||||
continue
|
||||
}
|
||||
|
||||
const output = result.status[agent].completed
|
||||
|
||||
// Parse action result
|
||||
const actionResult = parseActionResult(output)
|
||||
|
||||
console.log(`\n[Iteration ${iteration}] Action: ${actionResult.action}, Status: ${actionResult.status}`)
|
||||
|
||||
// Update iteration in state
|
||||
state = readLoopState(loopId)
|
||||
state.current_iteration = iteration
|
||||
state.updated_at = getUtc8ISOString()
|
||||
Write(`.workflow/.loop/${loopId}.json`, JSON.stringify(state, null, 2))
|
||||
|
||||
// Handle different outcomes
|
||||
switch (actionResult.next_action) {
|
||||
case 'COMPLETED':
|
||||
console.log('Loop completed successfully')
|
||||
continueLoop = false
|
||||
break
|
||||
|
||||
case 'PAUSED':
|
||||
console.log('Loop paused by API, exiting gracefully')
|
||||
continueLoop = false
|
||||
break
|
||||
|
||||
case 'STOPPED':
|
||||
console.log('Loop stopped by API')
|
||||
continueLoop = false
|
||||
break
|
||||
|
||||
case 'WAITING_INPUT':
|
||||
// Interactive mode: display menu, get user choice
|
||||
if (mode === 'interactive') {
|
||||
const userChoice = await displayMenuAndGetChoice(actionResult)
|
||||
|
||||
send_input({
|
||||
id: agent,
|
||||
message: `
|
||||
## USER INPUT RECEIVED
|
||||
|
||||
Action selected: ${userChoice.action}
|
||||
${userChoice.data ? `Additional data: ${JSON.stringify(userChoice.data)}` : ''}
|
||||
|
||||
## EXECUTE SELECTED ACTION
|
||||
|
||||
Read action instructions and execute: ${userChoice.action}
|
||||
Update state and progress files accordingly.
|
||||
Output ACTION_RESULT when complete.
|
||||

|
||||
})
|
||||
}
|
||||
break

${actionResult.message ? `Message: ${actionResult.message}` : ''}
|
||||
|
||||
## EXECUTE NEXT ACTION
|
||||
|
||||
Continue with: ${actionResult.next_action}
|
||||
Read action instructions and execute.
|
||||
Output ACTION_RESULT when complete.
|
||||
`

})
|

||||
continueLoop = false
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Step 2.3: Iteration Limit Check
|
||||
|
||||
```javascript
|
||||
if (iteration >= maxIterations) {
|
||||
console.log(`\nReached maximum iterations (${maxIterations})`)
|
||||
console.log('Consider breaking down the task or taking a break.')
|
||||
}
|
||||
```
|
||||
|
||||
### Step 2.4: Cleanup
|
||||
|
||||
```javascript
|
||||
close_agent({ id: agent })
|
||||
|
||||
console.log('\n=== CCW Loop Orchestrator Finished ===')
|
||||
|
||||
const finalState = readLoopState(loopId)
|
||||
return {
|
||||
status: finalState.status,
|
||||
loop_id: loopId,
|
||||
iterations: iteration,
|
||||
final_state: finalState
|
||||
}
|
||||
```
|
||||
|
||||
## Helper Functions
|
||||
|
||||
### parseActionResult
|
||||
|
||||
```javascript
|
||||
function parseActionResult(output) {
|
||||
const result = {
|
||||
action: 'unknown',
|
||||
status: 'unknown',
|
||||
message: '',
|
||||
state_updates: {},
|
||||
next_action: 'NONE'
|
||||
}
|
||||
|
||||
// Parse ACTION_RESULT block
|
||||
const actionMatch = output.match(/ACTION_RESULT:\s*([\s\S]*?)(?:FILES_UPDATED:|NEXT_ACTION_NEEDED:|$)/)
|
||||
if (actionMatch) {
|
||||
const lines = actionMatch[1].split('\n')
|
||||
for (const line of lines) {
|
||||
const match = line.match(/^-\s*(\w+):\s*(.+)$/)
|
||||
if (match) {
|
||||
const [, key, value] = match
|
||||
if (key === 'state_updates') {
|
||||
try {
|
||||
result.state_updates = JSON.parse(value)
|
||||
} catch (e) {
|
||||
// Try parsing multi-line JSON
|
||||
}
|
||||
} else {
|
||||
result[key] = value.trim()
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
// Parse NEXT_ACTION_NEEDED
|
||||
const nextMatch = output.match(/NEXT_ACTION_NEEDED:\s*(\S+)/)
|
||||
if (nextMatch) {
|
||||
result.next_action = nextMatch[1]
|
||||
}
|

}
|
||||
```
|
||||
|
||||
### displayMenuAndGetChoice
|
||||
|
||||
```javascript
|
||||
async function displayMenuAndGetChoice(actionResult) {
|
||||
const menuMatch = actionResult.message.match(/MENU_OPTIONS:\s*([\s\S]*?)(?:WAITING_INPUT:|$)/)
|
||||
|
||||
if (menuMatch) {
|
||||
console.log('\n' + menuMatch[1])
|
||||
}
|
||||
|
||||
const response = await AskUserQuestion({
|
||||
questions: [{
|
||||
question: "Select next action:",
|
||||
header: "Action",
|
||||
multiSelect: false,
|
||||
options: [
|
||||
{ label: "develop", description: "Continue development" },
|

{ label: "debug", description: "Start debugging" },
|
||||
{ label: "validate", description: "Run validation" },
|
||||
{ label: "complete", description: "Complete loop" },

})
|
||||
|
||||
return { action: response["Action"] }
|
||||
}
|
||||
```
|
||||
|
||||
## Termination Conditions
|
||||
|
||||
1. **API Paused**: `state.status === 'paused'` (Skill exits, wait for resume)
|
||||
2. **API Stopped**: `state.status === 'failed'` (Skill terminates)
|
||||
3. **Task Complete**: `NEXT_ACTION_NEEDED === 'COMPLETED'`
|
||||
4. **Iteration Limit**: `current_iteration >= max_iterations`
|
||||
5. **User Exit**: User selects 'exit' in interactive mode
|
||||
|
||||
## Output
|
||||
|
||||
- **Variable**: `finalState` - Final loop state after all iterations
|
||||
- **Return**: `{ status, loop_id, iterations, final_state }`
|
||||
- **TodoWrite**: Mark Phase 2 completed
|
||||
|
||||
## Next Phase
|
||||
|
||||
None. Phase 2 is the terminal phase of the orchestrator.
