Claude Code Graph

Generate a structural analysis and dependency graph of a Claude Code plugin. Outputs component inventory, dependency mappings, and Mermaid visualization.

Context

!ls .claude-plugin/plugin.json 2>/dev/null && echo "Plugin detected" || echo "No plugin.json - specify path"

Workflow

Phase 1: Discover Components

Plugin Manifest:

PLUGIN_PATH="${1:-.}"
cat "$PLUGIN_PATH/.claude-plugin/plugin.json" | jq '{name, version, description}'

Commands:

ls "$PLUGIN_PATH/commands/"*.md 2>/dev/null | wc -l

Skills:

ls -d "$PLUGIN_PATH/skills/"*/ 2>/dev/null | wc -l

Hooks:

cat "$PLUGIN_PATH/hooks/hooks.json" 2>/dev/null | jq '.hooks | keys'

Agents:

ls "$PLUGIN_PATH/agents/"*.md 2>/dev/null | wc -l

Phase 2: Parse Metadata

For each component, extract name and description dynamically:

Command Descriptions:

for f in "$PLUGIN_PATH/commands/"*.md; do
  name=$(basename "$f" .md)
  desc=$(sed -n '/^description:/s/description: *//p' "$f" | head -1)
  printf "%-28s %s\n" "$name" "$desc"
done

Skill Descriptions:

for d in "$PLUGIN_PATH/skills/"*/; do
  name=$(basename "$d")
  desc=$(sed -n '/^description:/s/description: *//p' "$d/SKILL.md" | head -1)
  printf "%-28s %s\n" "$name" "$desc"
done

Hook Scripts:

jq -r '.hooks | to_entries[] | .key as $event | .value[] | .hooks[] |
  "\($event)|\(.matcher // "*")|\(.command | split("/") | last)"' \
  "$PLUGIN_PATH/hooks/hooks.json"

Agent Descriptions:

for f in "$PLUGIN_PATH/agents/"*.md; do
  name=$(basename "$f" .md)
  desc=$(sed -n '/^description:/s/description: *//p' "$f" | head -1)
  echo "$name|$desc"
done

Phase 3: Build Dependency Graph

Command → Skill:

Look for See skills/*/SKILL.md patterns in command files.

Skill → Tools:

Extract allowed-tools from frontmatter.

Skill → Skill:

Look for Task tool usage with skill references, or @skill-name patterns.

Hook → Event:

Parse hooks.json structure:

{
  "hooks": {
    "EVENT_TYPE": [
      { "matcher": "...", "hooks": ["script.sh"] }
    ]
  }
}

Phase 4: Generate Output

JSON Structure

{
  "plugin": {
    "name": "plugin-name",
    "version": "1.0.0",
    "path": "/path/to/plugin"
  },
  "components": {
    "commands": [
      { "name": "commit", "file": "commands/commit.md", "description": "...", "allowedTools": [...] }
    ],
    "skills": [
      { "name": "atomic-commits", "file": "skills/atomic-commits/SKILL.md", "description": "...", "allowedTools": [...] }
    ],
    "hooks": [
      { "event": "PreToolUse", "matcher": "Bash", "script": "block-manual-release.sh" }
    ],
    "agents": []
  },
  "dependencies": {
    "commandToSkill": {
      "commit": "atomic-commits"
    },
    "skillToTools": {
      "atomic-commits": ["Read", "Write", "Bash", "Glob"]
    },
    "skillToSkill": {
      "release": ["claude-code-guide"]
    },
    "hookToEvent": {
      "block-manual-release.sh": "PreToolUse:Bash"
    }
  },
  "stats": {
    "totalCommands": 27,
    "totalSkills": 20,
    "totalHooks": 13,
    "totalAgents": 1
  }
}

Mermaid Diagram

Generate a Mermaid flowchart showing relationships:

graph TD
    subgraph Commands
        cmd_commit["/commit"]
        cmd_release["/release"]
    end

    subgraph Skills
        skill_atomic["atomic-commits"]
        skill_release["release"]
    end

    subgraph Hooks
        hook_block["block-manual-release"]
    end

    subgraph Events
        event_pre["PreToolUse:Bash"]
    end

    cmd_commit --> skill_atomic
    cmd_release --> skill_release
    hook_block --> event_pre

Arguments

Output Formats

Default (Terminal-Friendly)

Optimized for Claude Code's output window. Uses Unicode box characters, aligned columns, and visual grouping. All data is read dynamically from the filesystem at invocation time.

│  {plugin.name} v{plugin.version}                                             │
│  {plugin.description}                                                        │

--markdown (GitHub/Docs)

Uses markdown tables and collapsible mermaid diagram:

## Plugin Analysis: bluera-base v0.31.5

| Type | Count |
|------|-------|
| Commands | 29 |
| Skills | 29 |
| Hooks | 12 |

--mermaid (Diagram Only)

Outputs just the Mermaid flowchart for embedding in documentation.

--json (Machine Readable)

Full JSON structure for programmatic use.

Constraints

• Read-only analysis (no modifications)
• Fail fast if plugin.json missing (required file)
• Support both current directory and explicit path
• Generate valid Mermaid syntax
