Codebase Exploration

Multi-angle codebase exploration using 3-5 parallel agents.

Quick Start

/ork:explore authentication

Opus 4.6: Exploration agents use native adaptive thinking for deeper pattern recognition across large codebases.

STEP 0: Verify User Intent with AskUserQuestion

BEFORE creating tasks, clarify what the user wants to explore:

AskUserQuestion(
  questions=[{
    "question": "What aspect do you want to explore?",
    "header": "Focus",
    "options": [
      {"label": "Full exploration (Recommended)", "description": "Code structure + data flow + architecture + health assessment", "markdown": "```\nFull Exploration (8 phases)\n───────────────────────────\n  4 parallel explorer agents:\n  ┌──────────┐ ┌──────────┐\n  │ Structure│ │ Data     │\n  │ Explorer │ │ Flow     │\n  ├──────────┤ ├──────────┤\n  │ Pattern  │ │ Product  │\n  │ Analyst  │ │ Context  │\n  └──────────┘ └──────────┘\n         ▼\n  ┌──────────────────────┐\n  │ Code Health    N/10  │\n  │ Dep Hotspots   map   │\n  │ Architecture   diag  │\n  └──────────────────────┘\n  Output: Full exploration report\n```"},
      {"label": "Code structure only", "description": "Find files, classes, functions related to topic", "markdown": "```\nCode Structure\n──────────────\n  Grep ──▶ Glob ──▶ Map\n\n  Output:\n  ├── File tree (relevant)\n  ├── Key classes/functions\n  ├── Import graph\n  └── Entry points\n  No agents — direct search\n```"},
      {"label": "Data flow", "description": "Trace how data moves through the system", "markdown": "```\nData Flow Trace\n───────────────\n  Input ──▶ Transform ──▶ Output\n    │          │            │\n    ▼          ▼            ▼\n  [API]    [Service]    [DB/Cache]\n\n  Traces: request lifecycle,\n  state mutations, side effects\n  Agent: 1 data-flow explorer\n```"},
      {"label": "Architecture patterns", "description": "Identify design patterns and integrations", "markdown": "```\nArchitecture Analysis\n─────────────────────\n  ┌─────────────────────┐\n  │ Detected Patterns    │\n  │ ├── MVC / Hexagonal  │\n  │ ├── Event-driven?    │\n  │ ├── Service layers   │\n  │ └── External APIs    │\n  ├─────────────────────┤\n  │ Integration Map      │\n  │ DB ←→ Cache ←→ Queue │\n  └─────────────────────┘\n  Agent: backend-system-architect\n```"},
      {"label": "Quick search", "description": "Just find relevant files, skip deep analysis", "markdown": "```\nQuick Search (~30s)\n───────────────────\n  Grep + Glob ──▶ File list\n\n  Output:\n  ├── Matching files\n  ├── Line references\n  └── Brief summary\n  No agents, no health check,\n  no report generation\n```"}
    ],
    "multiSelect": false
  }]
)

Based on answer, adjust workflow:

• Full exploration: All phases, all parallel agents
• Code structure only: Skip phases 5-7 (health, dependencies, product)
• Data flow: Focus phase 3 agents on data tracing
• Architecture patterns: Focus on backend-system-architect agent
• Quick search: Skip to phases 1-2 only, return file list

STEP 0b: Select Orchestration Mode

MCP Probe

ToolSearch(query="select:mcp__memory__search_nodes")
Write(".claude/chain/capabilities.json", { memory, timestamp })

if capabilities.memory:
  mcp__memory__search_nodes({ query: "architecture decisions for {path}" })
  # Enrich exploration with past decisions

Exploration Handoff

After exploration completes, write results for downstream skills:

Write(".claude/chain/exploration.json", JSON.stringify({
  "phase": "explore", "skill": "explore",
  "timestamp": now(), "status": "completed",
  "outputs": {
    "architecture_map": { ... },
    "patterns_found": ["repository", "service-layer"],
    "complexity_hotspots": ["src/auth/", "src/payments/"]
  }
}))

Choose Agent Teams (mesh) or Task tool (star):

1. Agent Teams mode (GA since CC 2.1.33) → recommended for 4+ agents
2. Task tool mode → for quick/single-focus exploration
3. ORCHESTKIT_FORCE_TASK_TOOL=1 → Task tool (override)

Fallback: If Agent Teams encounters issues, fall back to Task tool for remaining exploration.

Task Management (MANDATORY)

BEFORE doing ANYTHING else, create tasks to show progress:

# 1. Create main task IMMEDIATELY
TaskCreate(subject="Explore: {topic}", description="Deep codebase exploration for {topic}", activeForm="Exploring {topic}")

# 2. Create subtasks for each phase
TaskCreate(subject="Initial file search", activeForm="Searching files")                # id=2
TaskCreate(subject="Check knowledge graph", activeForm="Checking memory")              # id=3
TaskCreate(subject="Launch exploration agents", activeForm="Dispatching explorers")     # id=4
TaskCreate(subject="Assess code health (0-10)", activeForm="Assessing code health")    # id=5
TaskCreate(subject="Map dependency hotspots", activeForm="Mapping dependencies")       # id=6
TaskCreate(subject="Add product perspective", activeForm="Adding product context")     # id=7
TaskCreate(subject="Generate exploration report", activeForm="Generating report")      # id=8

# 3. Set dependencies for sequential phases
TaskUpdate(taskId="3", addBlockedBy=["2"])  # Memory check needs file search first
TaskUpdate(taskId="4", addBlockedBy=["3"])  # Agents need memory context
TaskUpdate(taskId="5", addBlockedBy=["4"])  # Health needs exploration done
TaskUpdate(taskId="6", addBlockedBy=["4"])  # Hotspots need exploration done
TaskUpdate(taskId="7", addBlockedBy=["4"])  # Product needs exploration done
TaskUpdate(taskId="8", addBlockedBy=["5", "6", "7"])  # Report needs all analysis done

# 4. Before starting each task, verify it's unblocked
task = TaskGet(taskId="2")  # Verify blockedBy is empty

# 5. Update status as you progress
TaskUpdate(taskId="2", status="in_progress")  # When starting
TaskUpdate(taskId="2", status="completed")    # When done — repeat for each subtask

Workflow Overview

Progressive Output (CC 2.1.76)

Output findings incrementally as each phase completes — don't batch until the report:

For Phase 3 parallel agents, output each agent's findings as soon as it returns — don't wait for all 4 explorers. Early findings from one agent may answer the user's question before remaining agents complete, allowing early termination.

Phase 1: Initial Search

# PARALLEL - Quick searches
Grep(pattern="$ARGUMENTS[0]", output_mode="files_with_matches")
Glob(pattern="**/*$ARGUMENTS[0]*")

Phase 2: Memory Check

mcp__memory__search_nodes(query="$ARGUMENTS[0]")
mcp__memory__search_nodes(query="architecture")

Phase 3: Parallel Deep Exploration (4 Agents)

Load Read("${CLAUDE_SKILL_DIR}/rules/exploration-agents.md") for Task tool mode prompts.

Load Read("${CLAUDE_SKILL_DIR}/rules/agent-teams-mode.md") for Agent Teams alternative.

Phase 4: AI System Exploration (If Applicable)

For AI/ML topics, add exploration of: LangGraph workflows, prompt templates, RAG pipeline, caching strategies.

Phase 5: Code Health Assessment

Load Read("${CLAUDE_SKILL_DIR}/rules/code-health-assessment.md") for agent prompt. Load Read("${CLAUDE_SKILL_DIR}/references/code-health-rubric.md") for scoring criteria.

Phase 6: Dependency Hotspot Map

Load Read("${CLAUDE_SKILL_DIR}/rules/dependency-hotspot-analysis.md") for agent prompt. Load Read("${CLAUDE_SKILL_DIR}/references/dependency-analysis.md") for metrics.

Phase 7: Product Perspective

Load Read("${CLAUDE_SKILL_DIR}/rules/product-perspective.md") for agent prompt. Load Read("${CLAUDE_SKILL_DIR}/references/findability-patterns.md") for best practices.

Phase 8: Generate Report

Load Read("${CLAUDE_SKILL_DIR}/references/exploration-report-template.md").

Common Exploration Queries

• "How does authentication work?"
• "Where are API endpoints defined?"
• "Find all usages of EventBroadcaster"
• "What's the workflow for content analysis?"
