- **Autonomous completion**: **Execute all tasks without user interruption until workflow complete**
|

|
||||
## Flow Control Execution
|
||||
**[FLOW_CONTROL]** marker indicates sequential step execution required for context gathering and preparation. **These steps are executed BY THE AGENT, not by the workflow:execute command.**
|
||||
**[FLOW_CONTROL]** marker indicates task JSON contains `flow_control.pre_analysis` steps for context preparation.
|
||||
|
||||
### Flow Control Rules
|
||||
1. **Auto-trigger**: When `task.flow_control.pre_analysis` array exists in task JSON, agents execute these steps
|
||||
2. **Sequential Processing**: Agents execute steps in order, accumulating context including artifacts
|
||||
3. **Variable Passing**: Agents use `[variable_name]` syntax to reference step outputs including artifact content
|
||||
4. **Error Handling**: Agents follow step-specific error strategies (`fail`, `skip_optional`, `retry_once`)
|
||||
5. **Artifacts Priority**: When artifacts exist in task.context.artifacts, load synthesis specifications first
|
||||
### Orchestrator Responsibility
|
||||
- Pass complete task JSON to agent (including `flow_control` block)
|
||||
- Provide session paths for artifact access
|
||||
- Monitor agent completion
|
||||
|
||||
### Execution Pattern
|
||||
```
|
||||
Step 1: load_dependencies → dependency_context
|
||||
Step 2: analyze_patterns [dependency_context] → pattern_analysis
|
||||
Step 3: implement_solution [pattern_analysis] [dependency_context] → implementation
|
||||
```
|
||||
### Agent Responsibility
|
||||
- Parse `flow_control.pre_analysis` array from JSON
|
||||
- Execute steps sequentially with variable substitution
|
||||
- Accumulate context from artifacts and dependencies
|
||||
- Follow error handling per `step.on_error`
|
||||
- Complete implementation using accumulated context
|
||||
|
||||
### Context Accumulation Process (Executed by Agents)
|
||||
- **Load Artifacts**: Agents retrieve synthesis specifications and brainstorming outputs from `context.artifacts`
|
||||
- **Load Dependencies**: Agents retrieve summaries from `context.depends_on` tasks
|
||||
- **Execute Analysis**: Agents run CLI tools with accumulated context including artifacts
|
||||
- **Prepare Implementation**: Agents build comprehensive context for implementation
|
||||
- **Continue Implementation**: Agents use all accumulated context including artifacts for task execution
|
||||
**Orchestrator does NOT execute flow control steps - Agent interprets and executes them from JSON.**

## Batch Execution with Dependency Graph
|
||||
|
||||
### Parallel Execution Algorithm
|
||||
**Core principle**: Execute independent tasks concurrently in batches based on dependency graph.
|
||||
|
||||
#### Algorithm Steps
|
||||
```javascript
|
||||
function executeBatchWorkflow(sessionId) {
|
||||
// 1. Build dependency graph from task JSONs
|
||||
const graph = buildDependencyGraph(`.workflow/${sessionId}/.task/*.json`);
|
||||
|
||||
// 2. Process batches until graph is empty
|
||||
while (!graph.isEmpty()) {
|
||||
// 3. Identify current batch (tasks with in-degree = 0)
|
||||
const batch = graph.getNodesWithInDegreeZero();
|
||||
|
||||
// 4. Check for parallel execution opportunities
|
||||
const parallelGroups = groupByExecutionGroup(batch);
|
||||
|
||||
// 5. Execute batch concurrently
|
||||
await Promise.all(
|
||||
parallelGroups.map(group => executeBatch(group))
|
||||
);
|
||||
|
||||
// 6. Update graph: remove completed tasks and their edges
|
||||
graph.removeNodes(batch);
|
||||
|
||||
// 7. Update TodoWrite to reflect completed batch
|
||||
updateTodoWriteAfterBatch(batch);
|
||||
}
|
||||
|
||||
// 8. All tasks complete - auto-complete session
|
||||
SlashCommand("/workflow:session:complete");
|
||||
}
|
||||
|
||||
function buildDependencyGraph(taskFiles) {
|
||||
const tasks = loadAllTaskJSONs(taskFiles);
|
||||
const graph = new DirectedGraph();
|
||||
|
||||
tasks.forEach(task => {
|
||||
graph.addNode(task.id, task);
|
||||
|
||||
// Add edges for dependencies
|
||||
task.context.depends_on?.forEach(depId => {
|
||||
graph.addEdge(depId, task.id); // Edge from dependency to task
|
||||
});
|
||||
});
|
||||
|
||||
return graph;
|
||||
}
|
||||
|
||||
function groupByExecutionGroup(tasks) {
|
||||
const groups = {};
|
||||
|
||||
tasks.forEach(task => {
|
||||
const groupId = task.meta.execution_group || task.id;
|
||||
if (!groups[groupId]) groups[groupId] = [];
|
||||
groups[groupId].push(task);
|
||||
});
|
||||
|
||||
return Object.values(groups);
|
||||
}
|
||||
|
||||
async function executeBatch(tasks) {
|
||||
// Execute all tasks in batch concurrently
|
||||
return Promise.all(
|
||||
tasks.map(task => executeTask(task))
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
#### Execution Group Rules
|
||||
1. **Same `execution_group` ID** → Execute in parallel (independent, different contexts)
|
||||
2. **No `execution_group` (null)** → Execute sequentially (has dependencies)
|
||||
3. **Different `execution_group` IDs** → Execute in parallel (independent batches)
|
||||
4. **Same `context_signature`** → Should have been merged (warning if not)
|
||||
|
||||
#### Parallel Execution Example
|
||||
```
|
||||
Batch 1 (no dependencies):
|
||||
- IMPL-1.1 (execution_group: "parallel-auth-api") → Agent 1
|
||||
- IMPL-1.2 (execution_group: "parallel-ui-comp") → Agent 2
|
||||
- IMPL-1.3 (execution_group: "parallel-db-schema") → Agent 3
|
||||
|
||||
Wait for Batch 1 completion...
|
||||
|
||||
Batch 2 (depends on Batch 1):
|
||||
- IMPL-2.1 (execution_group: null, depends_on: [IMPL-1.1, IMPL-1.2]) → Agent 1
|
||||
|
||||
Wait for Batch 2 completion...
|
||||
|
||||
Batch 3 (independent of Batch 2):
|
||||
- IMPL-3.1 (execution_group: "parallel-tests-1") → Agent 1
|
||||
- IMPL-3.2 (execution_group: "parallel-tests-2") → Agent 2

prompt="**TASK EXECUTION WITH FULL JSON LOADING**
|
||||
prompt="**EXECUTE TASK FROM JSON**
|
||||
|
||||
## STEP 1: Load Complete Task JSON
|
||||
**MANDATORY**: First load the complete task JSON from: {session.task_json_path}
|
||||
## Task JSON Location
|
||||
{session.task_json_path}
|
||||
|
||||
cat {session.task_json_path}
|
||||
## Instructions
|
||||
1. **Load Complete Task JSON**: Read and validate all fields (id, title, status, meta, context, flow_control)
|
||||
2. **Execute Flow Control**: If `flow_control.pre_analysis` exists, execute steps sequentially:
|
||||
- Load artifacts (synthesis-specification.md, role analyses) using commands in each step
|
||||
- Accumulate context from step outputs using variable substitution [variable_name]
|
||||
- Handle errors per step.on_error (skip_optional | fail | retry_once)
|
||||
3. **Implement Solution**: Follow `flow_control.implementation_approach` using accumulated context
|
||||
4. **Complete Task**:
|
||||
- Update task status: `jq '.status = \"completed\"' {session.task_json_path} > temp.json && mv temp.json {session.task_json_path}`
|
||||
- Update TODO list: {session.todo_list_path}
|
||||
- Generate summary: {session.summaries_dir}/{task.id}-summary.md
|
||||
- Check workflow completion and call `/workflow:session:complete` if all tasks done
|
||||
|
||||
**CRITICAL**: Validate all 5 required fields are present:
|
||||
- id, title, status, meta, context, flow_control
|
||||
## Context Sources (All from JSON)
|
||||
- Requirements: `context.requirements`
|
||||
- Focus Paths: `context.focus_paths`
|
||||
- Acceptance: `context.acceptance`
|
||||
- Artifacts: `context.artifacts` (synthesis specs, brainstorming outputs)
|
||||
- Dependencies: `context.depends_on`
|
||||
- Target Files: `flow_control.target_files`
|
||||
|
||||
## STEP 2: Task Definition (From Loaded JSON)
|
||||
**ID**: Use id field from JSON
|
||||
**Title**: Use title field from JSON
|
||||
**Type**: Use meta.type field from JSON
|
||||
**Agent**: Use meta.agent field from JSON
|
||||
**Status**: Verify status is pending or active
|
||||
## Session Paths
|
||||
- Workflow Dir: {session.workflow_dir}
|
||||
- TODO List: {session.todo_list_path}
|
||||
- Summaries: {session.summaries_dir}
|
||||
- Flow Context: {flow_context.step_outputs}
|
||||
|
||||
## STEP 3: Flow Control Execution (if flow_control.pre_analysis exists)
|
||||
**AGENT RESPONSIBILITY**: Execute pre_analysis steps sequentially from loaded JSON:
|
||||
|
||||
**PRIORITY: Artifact Loading Steps First**
|
||||
1. **Load Synthesis Specification** (if present): Priority artifact loading for consolidated design
|
||||
2. **Load Individual Artifacts** (fallback): Load role-specific brainstorming outputs if synthesis unavailable
|
||||
3. **Execute Remaining Steps**: Continue with other pre_analysis steps
|
||||
|
||||
For each step in flow_control.pre_analysis array:
|
||||
1. Execute step.command/commands with variable substitution (support both single command and commands array)
|
||||
2. Store output to step.output_to variable
|
||||
3. Handle errors per step.on_error strategy (skip_optional, fail, retry_once)
|
||||
4. Pass accumulated variables to next step including artifact context
|
||||
|
||||
**Special Artifact Loading Commands**:
|
||||
- Use `bash(ls path 2>/dev/null || echo 'file not found')` for artifact existence checks
|
||||
- Use `Read(path)` for loading artifact content
|
||||
- Use `find` commands for discovering multiple artifact files
|
||||
- Reference artifacts in subsequent steps using output variables: [synthesis_specification], [individual_artifacts]
|
||||
|
||||
## STEP 4: Implementation Context (From JSON context field)
|
||||
**Requirements**: Use context.requirements array from JSON
|
||||
**Focus Paths**: Use context.focus_paths array from JSON
|
||||
**Acceptance Criteria**: Use context.acceptance array from JSON
|
||||
**Dependencies**: Use context.depends_on array from JSON
|
||||
**Parent Context**: Use context.inherited object from JSON
|
||||
**Artifacts**: Use context.artifacts array from JSON (synthesis specifications, brainstorming outputs)
|
||||
**Target Files**: Use flow_control.target_files array from JSON
|
||||
**Implementation Approach**: Use flow_control.implementation_approach object from JSON (with artifact integration)
|
||||
|
||||
## STEP 5: Session Context (Provided by workflow:execute)
|
||||
**Workflow Directory**: {session.workflow_dir}
|
||||
**TODO List Path**: {session.todo_list_path}
|
||||
**Summaries Directory**: {session.summaries_dir}
|
||||
**Task JSON Path**: {session.task_json_path}
|
||||
**Flow Context**: {flow_context.step_outputs}
|
||||
|
||||
## STEP 6: Agent Completion Requirements
|
||||
1. **Load Task JSON**: Read and validate complete task structure
|
||||
2. **Execute Flow Control**: Run all pre_analysis steps if present
|
||||
3. **Implement Solution**: Follow implementation_approach from JSON
|
||||
4. **Update Progress**: Mark task status in JSON as completed
|
||||
5. **Update TODO List**: Update TODO_LIST.md at provided path
|
||||
6. **Generate Summary**: Create completion summary in summaries directory
|
||||
7. **Check Workflow Complete**: After task completion, check if all workflow tasks done
|
||||
8. **Auto-Complete Session**: If all tasks completed, call SlashCommand(\"/workflow:session:complete\")
|
||||
|
||||
**JSON UPDATE COMMAND**:
|
||||
Update task status to completed using jq:
|
||||
jq '.status = \"completed\"' {session.task_json_path} > temp.json && mv temp.json {session.task_json_path}
|
||||
|
||||
**WORKFLOW COMPLETION CHECK**:
|
||||
After updating task status, check if workflow is complete:

|
||||
completed_tasks=\$(find .workflow/*/\.summaries/ -name "*.md" -type f 2>/dev/null | wc -l)

### Phase 2: Task JSON Generation
|

|
||||
#### Task Decomposition Standards
|
||||
**Core Principle: Task Merging Over Decomposition**
|
||||
- **Merge Rule**: Execute together when possible
|
||||
- **Decompose Only When**:
|
||||
- Excessive workload (>2500 lines or >6 files)
|
||||
- Different tech stacks or domains
|
||||
- Sequential dependency blocking
|
||||
- Parallel execution needed
|
||||
**Core Principle: Shared Context Merging + Independent Parallelization**
|
||||
- **Primary Rule**: **Shared context → Merge tasks** (avoid redundant context loading, tasks have inherent relationships)
|
||||
- **Secondary Rule**: **Different contexts + No dependencies → Decompose for parallel execution**
|
||||
|
||||
**Context Analysis for Task Grouping**:
|
||||
1. **Shared Context Indicators** (→ Merge):
|
||||
- Same `focus_paths` (working on same modules/files)
|
||||
- Same tech stack/dependencies
|
||||
- Same `context.artifacts` references
|
||||
- Sequential logic flow within same feature
|
||||
- Common test fixtures/setup
|
||||
|
||||
2. **Independent Context Indicators** (→ Decompose):
|
||||
- Different `focus_paths` (separate modules)
|
||||
- Different tech stacks (frontend vs backend)
|
||||
- Different `context.artifacts` (using different brainstorming outputs)
|
||||
- No shared dependencies
|
||||
- Can be tested independently
|
||||
|
||||
**Decompose Only When**:
|
||||
- Different contexts + No shared dependencies (→ Parallel execution)
|
||||
- Excessive workload (>2500 lines or >6 files)
|
||||
- Sequential dependency requires blocking (IMPL-1 → IMPL-2)
|
||||
|
||||
**Task Limits**:
|
||||
- **Maximum 10 tasks** (hard limit)
|
||||
- **Function-based**: Complete units (logic + UI + tests + config)
|
||||
- **Hierarchy**: Flat (≤5) | Two-level (6-10) | Re-scope (>10)
|
||||
- **Parallel Groups**: Tasks with same `execution_group` ID are independent and run concurrently

|
||||
7. Create individual task JSON files in `.task/`
|
||||
4. **Analyze context signatures**: Compute hash of `focus_paths + artifacts` for each task
|
||||
5. **Group tasks by context**:
|
||||
- Tasks with same `context_signature` → Same context, should merge
|
||||
- Tasks with different `context_signature` + no `depends_on` → Independent, assign unique `execution_group`
|
||||
- Tasks with `depends_on` → Must be sequential, `execution_group = null`
|
||||
6. **Determine modification targets**: Extract specific code locations from analysis
|
||||
7. Build flow_control with artifact loading steps and target_files
|
||||
8. **CLI Execute Mode**: If `--cli-execute` flag present, generate Codex commands

#### Context Signature Algorithm
|
||||
```javascript
|
||||
// Compute context signature for task grouping
|
||||
function computeContextSignature(task) {
|
||||
const focusPathsStr = task.context.focus_paths.sort().join('|');
|
||||
const artifactsStr = task.context.artifacts.map(a => a.path).sort().join('|');
|
||||
const techStack = task.context.shared_context?.tech_stack?.sort().join('|') || '';
|
||||
|
||||
return hash(`${focusPathsStr}:${artifactsStr}:${techStack}`);
|
||||
}
|
||||
|
||||
// Group tasks by context signature
|
||||
function groupTasksByContext(tasks) {
|
||||
const groups = {};
|
||||
|
||||
tasks.forEach(task => {
|
||||
const signature = computeContextSignature(task);
|
||||
if (!groups[signature]) {
|
||||
groups[signature] = [];
|
||||
}
|
||||
groups[signature].push(task);
|
||||
});
|
||||
|
||||
return groups;
|
||||
}
|
||||
|
||||
// Assign execution groups for parallel tasks
|
||||
function assignExecutionGroups(tasks) {
|
||||
const contextGroups = groupTasksByContext(tasks);
|
||||
|
||||
Object.entries(contextGroups).forEach(([signature, groupTasks]) => {
|
||||
if (groupTasks.length === 1) {
|
||||
const task = groupTasks[0];
|
||||
// Single task with unique context
|
||||
if (!task.context.depends_on || task.context.depends_on.length === 0) {
|
||||
task.meta.execution_group = `parallel-${signature.slice(0, 8)}`;
|
||||
} else {
|
||||
task.meta.execution_group = null; // Sequential task
|
||||
}
|
||||
} else {
|
||||
// Multiple tasks with same context → Should be merged
|
||||
console.warn(`Tasks ${groupTasks.map(t => t.id).join(', ')} share context and should be merged`);
|
||||
// Merge tasks into single task
|
||||
return mergeTasks(groupTasks);
|
||||
}
|
||||
});
|
