Codebase Exploration

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

🎯 Quick Start

/ork:explore authentication

Opus 5: Exploration agents use native adaptive thinking for deeper pattern recognition across large codebases.

STEP -0.5: Effort-Aware Agent Scaling (CC 2.1.120+)

Read $CLAUDE_EFFORT to scale exploration depth before any other decision.

# CC 2.1.120+ env var; explicit --effort= overrides
EFFORT = os.environ.get("CLAUDE_EFFORT")
for token in "$ARGUMENTS".split():
    if token.startswith("--effort="):
        EFFORT = token.split("=", 1)[1]
EFFORT = EFFORT or "high"  # default

Effort	Agent count	Phases	Time
low	1 (structure-only)	1, 2, 8	~1 min
medium	2 (structure + data flow)	1, 2, 3 (subset), 8	~3 min
high (default)	4 (full parallel team)	1–8	~6 min
xhigh (Opus 5)	5 (+ uncertainty pass on health scores)	1–8 + caveats	~8 min

Override gate: if the user passes --effort=high explicitly while $CLAUDE_EFFORT is low, the flag wins. /ork:doctor warns when xhigh is requested without Opus 5.

---

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"},
      {"label": "Quick scan", "description": "Find relevant files + structure, skip deep analysis"},
      {"label": "Data flow", "description": "Trace how data moves through the system"},
      {"label": "Architecture patterns", "description": "Identify design patterns and integrations"}
    ],
    "multiSelect": false
  }]
)

Based on answer, adjust workflow:

• Full exploration: All phases, all parallel agents
• Quick scan: Files + structure only (phases 1-2), skip health/deps/product — no deep agents
• Data flow: Focus phase 3 agents on data tracing
• Architecture patterns: Focus on backend-system-architect agent

STEP 0b: Select Orchestration Mode

MCP Probe

# memory is alwaysLoad in .mcp.json (CC 2.1.121+, #1541) — probe below kept as fallback for older CC:
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)

Aspect	Task Tool	Agent Teams
Discovery sharing	Lead synthesizes after all complete	Explorers share discoveries as they go
Cross-referencing	Lead connects dots	Data flow explorer alerts architecture explorer
Cost	~150K tokens	~400K tokens
Best for	Quick/focused searches	Deep full-codebase exploration

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

Model cost (CC 2.1.198+): the built-in Explore agent inherits the session model capped at Opus — it no longer runs on haiku. From a premium-model session (Opus, Fable), budget Explore fan-outs at Opus rates; there is no knob to pin the built-in Explore back to haiku. ork's own explorer agents can still pin a cheaper model via frontmatter.

🚨 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. 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

Phase	Activities	Output
1. Initial Search	Grep, Glob for matches	File locations
2. Memory Check	Search knowledge graph	Prior context
3. Deep Exploration	4 parallel explorers	Multi-angle analysis
4. AI System (if applicable)	LangGraph, prompts, RAG	AI-specific findings
5. Code Health	Rate code 0-10	Quality scores
6. Dependency Hotspots	Identify coupling	Hotspot visualization
7. Product Perspective	Business context	Findability suggestions
8. Report Generation	Compile findings	Actionable report

Progressive Output (CC 2.1.76)

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

After Phase	Show User
1. Initial Search	File matches, grep results
2. Memory Check	Prior decisions and relevant context
3. Deep Exploration	Each explorer agent's findings as they return
5. Code Health	Health score with dimension breakdown

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_PLUGIN_ROOT}/skills/explore/rules/exploration-agents.md") for Task tool mode prompts.

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

Phase 6: Dependency Hotspot Map

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

Phase 7: Product Perspective

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

Phase 8: Generate Report

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

Phase 8b: Emit Dashboard Spec (json-render)

Parse --render= from $ARGUMENTS. Default is both.

Mode	Behavior
markdown	Current behavior — markdown report only. No spec emitted.
json-render	Emit .claude/chain/explore-dashboard.json only. Skip markdown report.
both	Emit spec and markdown. Default — gives the human a report and downstream skills a structured handoff.

When emitting a spec:

1. Load the format and catalog: Read("${CLAUDE_PLUGIN_ROOT}/skills/explore/references/dashboard-spec.md"). Reference example: references/dashboard-example.json.
2. Build the spec object using only catalog component types: Card, StatGrid, DataTable, StatusBadge, BarMeter, Heatmap, Markdown.
3. Write to .claude/chain/explore-dashboard.json with compact JSON (no indentation) — minimizes token cost for downstream consumers.
4. Validate before declaring success:

node "${CLAUDE_PLUGIN_ROOT}/skills/explore/scripts/render-spec.mjs" .claude/chain/explore-dashboard.json --check

If validation fails (exit ≠ 0), do not emit — fall back to markdown-only and surface the error to the user. Never write a partial or invalid spec.

5. For --render=both, render the markdown view from the spec for consistency:

node "${CLAUDE_PLUGIN_ROOT}/skills/explore/scripts/render-spec.mjs" .claude/chain/explore-dashboard.json

Pipe the output into the user-facing markdown report (or use it as-is). This guarantees the JSON spec and markdown report stay in sync — a single source of truth.

Why this matters: Downstream skills (/ork:fix-issue, /ork:implement, /ork:create-pr) parse .claude/chain/explore-dashboard.json directly instead of re-reading 3000-token markdown. Measured: spec ≈ 580 tokens for the same content. Backwards-compatible: old chained workflows that read markdown keep working in both mode.

Phase 6.5 — Notebook summary (signal-fired, optional)

After the session synthesis lands, optionally invoke scripts/post_explore_summary.py <session-dir> to auto-emit a notebook-backed summary of the exploration. Self-skips on every non-happy-path so it never breaks the run:

python3 ${CLAUDE_PLUGIN_ROOT}/skills/explore/scripts/post_explore_summary.py "$CLAUDE_JOB_DIR"

Auto-skip conditions (all exit 0, all WARN-logged):

Skip reason	Trigger
signal absent	len(dirs_scanned) < 3 (or field missing on explore-output.json)
yg-mcp-core not importable	yg-mcp-core>=0.3.0 not installed (orchestkit is public; yg-mcp-core lives on private pypi.yonyon.ai — HQ-only)
hq-content MCP unreachable	MCP server down OR .mcp.json doesn't define hq-content

Session dir must contain explore-output.json (with dirs_scanned: list[str], optional synthesis: str, required notebook_id: str). Handoff JSON at <session-dir>/explore-summary.json records status (fired / skipped) and summary_path on success.

Mirrors the /ork:brainstorm post-synth podcast pattern from PR #1889. Closes orchestkit#1893.

Notes for long explorations

Oversized reads (CC 2.1.144+): Read returns a [PARTIAL view] truncated first page (not a hard error) when a whole-file read exceeds the token limit. When traversing large files, detect that notice and re-read with explicit offset/limit to page through the rest — never treat the partial as the full file.

When context fills (CC 2.1.141+): Use the rewind menu's "Summarize up to here" to compress earlier turns while keeping recent context, instead of restarting. Reactive compaction (CC 2.1.142+) now sizes the first summarize to the actual overflow, so a second mid-turn pass is rare.

Common Exploration Queries

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

Running unattended with /goal

Set a completion condition with /goal (CC 2.1.139+) and this skill will keep working across turns until the condition is met. Works in interactive, -p, and Remote Control. The overlay panel shows live elapsed / turns / tokens.

Example completion condition for this skill:

/goal until report.has_architecture_diagram AND patterns.detected_count >= 5, or stop after 10 turns

Stops when: codebase architecture diagram is generated and at least 5 design patterns have been classified. Compatible with claude.ai Remote Control runs.

Quality Bar

Done means all of these hold:

• Every architectural or data-flow claim cites concrete evidence (file:line or a file path), not prose assertion
• Code health is reported as 0-10 scores with a per-dimension breakdown, not a bare number
• Dependency hotspots / coupling are named along with the files that drive them
• The report includes an architecture or structure visualization for the explored scope
• If a json-render spec is emitted, it passes render-spec.mjs --check; on failure fall back to markdown-only and never write a partial spec
