Semantic Clusters

OpenClaw Integration: This skill is invoked by the Dojo Genesis plugin via /dojo run semantic-clusters. The agent receives project context automatically via the before_agent_start hook. Use dojo_get_context for full state, dojo_save_artifact to persist outputs, and dojo_update_state to record phase transitions and decisions.

Semantic Clusters Skill

Version: 1.0 Created: 2026-02-08 Author: Cruz + Manus (Cowork) Origin: Elevated from the repo-status skill's semantic clusters reference, which was codified from a live strategic-scout audit of Dojo Genesis (13 clusters, 333 Go files, 416 frontend files mapped). Lineage: strategic-scout (exploration) → repo-status (formalization) → this standalone skill.

I. The Philosophy: Behavior Over Location

Every codebase has two architectures:

1. The filesystem architecture — where files live. Directories, packages, modules. This is what ls shows you.
2. The behavioral architecture — what the system does. Capabilities that cross-cut directories, features that span layers.

Most people only see architecture #1. They think in terms of frontend/, backend/, utils/. But understanding comes from architecture #2 — the verbs.

A "chat" feature isn't in one directory. It's a component in the frontend, a handler in the backend, a state engine in a context, a streaming service, an SSE connection, and a set of tools. These parts live in 6 different directories. But they all serve one verb: CONVERSE.

Semantic clusters make the behavioral architecture visible. Each cluster is named with an action verb, and every significant component in the codebase maps to one (sometimes two) clusters. The result is a map of what the system can do — not just where its files happen to be.

II. When to Use This Skill

• Exploring a new codebase: Before diving into files, map the behavioral capabilities to build your mental model.
• Explaining a system: Clusters make better explanations than directory trees because they answer "what does it do?" not "where are the files?"
• Planning a refactor: Clusters reveal which components serve the same capability. Refactoring within a cluster is safer than across clusters.
• Auditing feature coverage: Clusters expose gaps — capabilities the system lacks or has only partially implemented.
• Identifying architectural confusion: If a component maps to 3+ clusters, it's probably doing too much. If a directory has components in 5 different clusters, it may need restructuring.
• Writing status documents: Section 4 of the status-template skill uses clusters. This skill provides the methodology.

III. The Starter Verbs

These 13 action verbs cover most software systems. Read references/verb-catalog.md for detailed definitions, component examples, and signals for each.

Not every project needs all 13. A simple CRUD app might only have CONVERSE, PERSIST, PRESENT, PROTECT, and BUILD. A complex AI platform might use all 13 plus custom ones.

IV. The Clustering Workflow

Step 1: Inventory First

You can't cluster what you haven't seen. Before clustering, you need a component inventory — a list of every significant component with its location, approximate LOC, and current status.

If you've already run the repo-status skill (Phase 2), use that inventory. Otherwise, walk the filesystem yourself:

# Get top-level shape
ls -la project-root/

# Recursively explore significant directories
find project-root/src -type f | head -50
find project-root/backend -type d

# Count LOC per directory
find project-root/backend -name "*.go" | xargs wc -l | tail -1

Step 2: Assign Verbs

For each significant component in your inventory, ask: "What verb describes what this does?"

Rules of thumb:

• Most components map to one verb. If you can't decide, pick the one that best describes the component's primary purpose.
• Some components legitimately serve two verbs (cross-cluster). This is fine — note both.
• If a component maps to three or more verbs, it's probably doing too much. Flag it as an architectural concern.
• If a component doesn't fit any verb, it might be dead code, or you might need a new verb (see Section V).

Step 3: Build Cluster Tables

For each verb that has components, create a subsection:

### [emoji] VERB — [Short Description]
> [One sentence explaining what this capability means.]

| Component | Location | Status | LOC |
|-----------|----------|--------|-----|
| [Name] | [path/] | [emoji] | [~number] |

**Health:** [emoji] [one-line assessment]
**Audit Notes:** [technical details, constraints, risks — 1-2 lines]

Choosing emojis for verbs:

Step 4: Identify Cross-Cluster Components

Some components serve multiple clusters. List these explicitly:

### Cross-Cluster Components
| Component | Directory | Primary Cluster | Secondary | Notes |
|-----------|-----------|----------------|-----------|-------|
| [Name] | [path/] | [VERB] | [VERB] | [Why] |

This table is gold for understanding coupling. Components that are cross-cluster are integration points — they're where changes in one capability can break another.

Step 5: Identify Orphans

Walk the directory tree and check: is every significant directory represented in at least one cluster?

Orphan directories — significant code that doesn't map to any cluster — signal one of three things:

1. Dead code that should be removed.
2. An emerging capability that deserves its own verb.
3. A gap in your analysis that needs a second look.

Document orphans explicitly. Don't sweep them under the rug.

Step 6: Write Health Assessments

For each cluster, write a 2-line health assessment:

• Health line: Overall emoji + one-sentence verdict.
• Audit Notes line: Key constraints, risks, or technical details.

Be honest. A cluster with 85% test coverage and active development is ✅. A cluster with no tests and a known security gap is ⚠️. A cluster that's completely broken is ❌.

V. Creating New Verbs

The 13 starter verbs are a starting point. Your project may need verbs not on the list.

Good custom verbs are specific and immediately communicative:

Bad custom verbs are vague and don't tell you anything:

• MANAGE (manage what?)
• PROCESS (process what?)
• HANDLE (handle what?)
• DO (everything "does" something)

The test: can someone read just the verb name and guess what kinds of components belong in that cluster? If yes, it's a good verb.

VI. Common Pitfalls

1. Over-clustering. Don't create 20 clusters for a 30-file project. If a cluster has only 1-2 components, merge it with a related cluster. A good rule: 4-8 clusters for small projects, 8-15 for large ones.

2. Under-clustering. Don't dump everything into PRESENT and PERSIST. If a cluster has 25+ components, consider splitting it. PRESENT might split into PRESENT (layout) and COMPOSE (content editing).

3. Confusing location with behavior. A component in frontend/src/components/ isn't automatically PRESENT. A dashboard that displays traces belongs in OBSERVE. A form that manages API keys belongs in PROTECT. Let the behavior dictate the cluster, not the directory.

4. Ignoring tests. Tests belong in BUILD, not in the cluster of the code they test. They're infrastructure, not capabilities.

5. Forgetting infrastructure. CI/CD, Docker, and deployment configs are real capabilities. BUILD is a real cluster, not an afterthought.

6. Treating clusters as hierarchical. Clusters are flat. REASON is not "above" ACT. They're peers — different capabilities of the same system. The component tables within each cluster may have internal hierarchy, but the clusters themselves don't.

VII. Using Clusters Beyond Status Documents

Semantic clusters have applications beyond the status-template:

• Architecture Decision Records (ADRs): Frame decisions by which cluster they affect. "This ADR impacts REASON and ORCHESTRATE."
• Sprint planning: Assign work by cluster. "This sprint we're focused on OBSERVE and PRESENT."
• Code review: Ask "which cluster does this PR touch?" A PR that modifies 4+ clusters deserves extra scrutiny.
• Onboarding: Walk new team members through clusters, not directories. "Let me explain what this system can DO."
• Technical debt tracking: Rate each cluster's health independently. Focus debt reduction on ⚠️ and ❌ clusters.

VIII. Quality Checklist

Before delivering your semantic cluster map, confirm:

• Every significant component maps to at least one cluster
• No cluster has fewer than 2 components (merge if so)
• No cluster has more than 20 components (split if so)
• Cross-cluster components are explicitly listed
• Orphan directories are documented and explained
• Each cluster has a health assessment with emoji + notes
• Custom verbs (if any) pass the "can you guess the contents?" test
• The cluster map covers both frontend and backend (if applicable)
• LOC estimates are approximate but not fictional
• The map tells a coherent story about what the system does
