Key Design Principles

1. Action-Driven Routing: request_user_input selects action, then load single phase
2. Progressive Phase Loading: Only read the selected phase document
3. CLI-First Data Access: All issue CRUD via ccw issue CLI commands
4. Auto Mode Support: -y flag skips action selection with auto-detection
5. Subagent Lifecycle: Explicit lifecycle management with spawn_agent → wait_agent → close_agent
6. Role Path Loading: Subagent roles loaded via path reference in MANDATORY FIRST STEPS

Auto Mode

When --yes or -y: Skip action selection, auto-detect action from input type.

Usage

issue-discover <input>
issue-discover [FLAGS] "<input>"

# Flags
-y, --yes              Skip all confirmations (auto mode)
--action <type>        Pre-select action: new|discover|discover-by-prompt

# Phase-specific flags
--priority <1-5>       Issue priority (new mode)
--perspectives <list>  Comma-separated perspectives (discover mode)
--external             Enable Exa research (discover mode)
--scope <pattern>      File scope (discover/discover-by-prompt mode)
--depth <level>        standard|deep (discover-by-prompt mode)
--max-iterations <n>   Max exploration iterations (discover-by-prompt mode)

# Examples
issue-discover https://github.com/org/repo/issues/42                              # Create from GitHub
issue-discover "Login fails with special chars"                                    # Create from text
issue-discover --action discover src/auth/**                                       # Multi-perspective discovery
issue-discover --action discover src/api/** --perspectives=security,bug            # Focused discovery
issue-discover --action discover-by-prompt "Check API contracts"                   # Prompt-driven discovery
issue-discover -y "auth broken"                                                    # Auto mode create

Execution Flow

Input Parsing:
   └─ Parse flags (--action, -y, --perspectives, etc.) and positional args

Action Selection:
   ├─ --action flag provided → Route directly
   ├─ Auto-detect from input:
   │   ├─ GitHub URL or #number → Create New (Phase 1)
   │   ├─ Path pattern (src/**, *.ts) → Discover (Phase 2)
   │   ├─ Short text (< 80 chars) → Create New (Phase 1)
   │   └─ Long descriptive text (≥ 80 chars) → Discover by Prompt (Phase 3)
   └─ Otherwise → request_user_input to select action
   └─ Initialize progress tracking: functions.update_plan([...phases])

Phase Execution (load one phase):
   ├─ Phase 1: Create New          → phases/01-issue-new.md
   ├─ Phase 2: Discover            → phases/02-discover.md
   └─ Phase 3: Discover by Prompt  → phases/03-discover-by-prompt.md

Post-Phase:
   └─ Summary + Next steps recommendation

Phase Reference Documents

Core Rules

1. Action Selection First: Always determine action before loading any phase
2. Single Phase Load: Only read the selected phase document, never load all phases
3. CLI Data Access: Use ccw issue CLI for all issue operations, NEVER read files directly
4. Content Preservation: Each phase contains complete execution logic from original commands
5. Auto-Detect Input: Smart input parsing reduces need for explicit --action flag
6. ⚠️ CRITICAL: DO NOT STOP: Continuous multi-phase workflow. After completing each phase, immediately proceed to next
7. Progressive Phase Loading: Read phase docs ONLY when that phase is about to execute
8. Explicit Lifecycle: Always close_agent after wait_agent completes to free resources

Input Processing

Auto-Detection Logic

function detectAction(input, flags) {
  // 1. Explicit --action flag
  if (flags.action) return flags.action;

  const trimmed = input.trim();

  // 2. GitHub URL → new
  if (trimmed.match(/github\.com\/[\w-]+\/[\w-]+\/issues\/\d+/) || trimmed.match(/^#\d+$/)) {
    return 'new';
  }

  // 3. Path pattern (contains **, /, or --perspectives) → discover
  if (trimmed.match(/\*\*/) || trimmed.match(/^src\//) || flags.perspectives) {
    return 'discover';
  }

  // 4. Short text (< 80 chars, no special patterns) → new
  if (trimmed.length > 0 && trimmed.length < 80 && !trimmed.includes('--')) {
    return 'new';
  }

  // 5. Long descriptive text → discover-by-prompt
  if (trimmed.length >= 80) {
    return 'discover-by-prompt';
  }

  // Cannot auto-detect → ask user
  return null;
}

Action Selection (request_user_input)

// When action cannot be auto-detected
const answer = functions.request_user_input({
  questions: [{
    header: "Action",
    id: "action",
    question: "What would you like to do?",
    options: [
      {
        label: "Create New Issue (Recommended)",
        description: "Create issue from GitHub URL, text description, or structured input"
      },
      {
        label: "Discover Issues",
        description: "Multi-perspective discovery: bug, security, test, quality, performance, etc."
      },
      {
        label: "Discover by Prompt",
        description: "Describe what to find — Gemini plans the exploration strategy iteratively"
      }
    ]
  }]
});  // BLOCKS (wait for user response)

// Route based on selection
// answer.answers.action.answers[0] → selected label
const actionMap = {
  "Create New Issue (Recommended)": "new",
  "Discover Issues": "discover",
  "Discover by Prompt": "discover-by-prompt"
};

// Initialize progress tracking (MANDATORY)
functions.update_plan([
  { id: "action-select", title: "Action Selection", status: "completed" },
  { id: "phase-exec", title: `Phase: ${selectedAction}`, status: "in_progress" },
  { id: "post-phase", title: "Post-Phase: Next Steps", status: "pending" }
])

Subagent API Reference

spawn_agent

Create a new subagent with task assignment.

const agentId = spawn_agent({
  agent_type: "{agent_type}",
  message: `
## TASK ASSIGNMENT

### MANDATORY FIRST STEPS (Agent Execute)
1. Execute: ccw spec load --category exploration
2. Execute: ccw spec load --category debug (known issues cross-reference)

## TASK CONTEXT
${taskContext}

## DELIVERABLES
${deliverables}
`
})

wait_agent

Get results from subagent (only way to retrieve results).

const result = wait_agent({
  targets: [agentId],
  timeout_ms: 600000  // 10 minutes
})

if (result.timed_out) {
  // Handle timeout - can use assign_task to prompt completion
}

// Check completion status
if (result.status[agentId].completed) {
  const output = result.status[agentId].completed;
}

assign_task

Assign new work to active subagent (for clarification or follow-up).

assign_task({
  target: agentId,
  items: [{ type: "text", text: `
## CLARIFICATION ANSWERS
${answers}

## NEXT STEP
Continue with plan generation.
` }]
})

close_agent

Clean up subagent resources (irreversible).

close_agent({ target: agentId })

Core Guidelines

Data Access Principle: Issues files can grow very large. To avoid context overflow:

ALWAYS use CLI commands for CRUD operations. NEVER read entire issues.jsonl directly.

Error Handling

Post-Phase Next Steps

Progress: functions.update_plan([{id: "phase-exec", status: "completed"}, {id: "post-phase", status: "in_progress"}])

After successful phase execution, recommend next action:

// After Create New (issue created)
functions.request_user_input({
  questions: [{
    header: "Next Step",
    id: "next_after_create",
    question: "Issue created. What next?",
    options: [
      { label: "Plan Solution (Recommended)", description: "Generate solution via issue-resolve" },
      { label: "Create Another", description: "Create more issues" },
      { label: "Done", description: "Exit workflow" }
    ]
  }]
});  // BLOCKS (wait for user response)
// answer.answers.next_after_create.answers[0] → selected label

// After Discover / Discover by Prompt (discoveries generated)
functions.request_user_input({
  questions: [{
    header: "Next Step",
    id: "next_after_discover",
    question: `Discovery complete: ${findings.length} findings, ${executableFindings.length} executable. What next?`,
    options: [
      { label: "Quick Plan & Execute (Recommended)", description: `Fix ${executableFindings.length} high-confidence findings directly` },
      { label: "Export to Issues", description: "Convert discoveries to issues" },
      { label: "Done", description: "Exit workflow" }
    ]
  }]
});  // BLOCKS (wait for user response)
// answer.answers.next_after_discover.answers[0] → selected label
// If "Quick Plan & Execute (Recommended)" → Read phases/04-quick-execute.md, execute

// Mark workflow complete
functions.update_plan([{ id: "post-phase", status: "completed" }])
