Skill: Skill Catalog Generator

Generate dynamic skill catalogs with network diagrams to visualize Alex's capabilities and track learning progress.

---

Purpose

This skill enables Alex to:

1. Generate skill catalogs — List all installed skills with categories, inheritance, and purposes
2. Create network diagrams — Mermaid flowcharts showing skill relationships
3. Track learning progress — Show which skills have been activated, user-created skills
4. Post-migration reporting — Display what skills are available after upgrade

---

Activation Triggers

• "show my skills" / "what skills do I have"
• "skill catalog" / "generate catalog"
• "skill network" / "show skill diagram"
• "learning progress" / "what have I learned"
• Post-migration completion
• /skills slash command

Generation Algorithm

Step 1: Scan Skills Directory

interface SkillInfo {
  name: string;
  category: string;
  inheritance: 'inheritable' | 'master-only' | 'heir:vscode' | 'heir:m365' | 'user'; // From SKILL_EXCLUSIONS in sync-architecture.cjs (default: inheritable)
  purpose: string;
  hasSynapses: boolean;
  connectionCount: number;
  lastModified: Date;
  isUserCreated: boolean;
  isTemporary: boolean;      // From synapses.json "temporary": true
  removeAfter?: string;      // From synapses.json "removeAfter"
  staleProne: boolean;       // True if skill depends on rapidly changing tech
}

async function scanSkills(skillsPath: string): Promise<SkillInfo[]> {
  const skills: SkillInfo[] = [];
  const folders = await fs.readdir(skillsPath);

  for (const folder of folders) {
    const skillPath = path.(skillsPath, folder);
     skillMd = path.(skillPath, );
     synapsesJson = path.(skillPath, );

     (! fs.(skillMd)) ;

     content =  fs.(skillMd, );
     synapses =  fs.(synapsesJson)
      ?  fs.(synapsesJson)
      : ;

    skills.({
      : folder,
      : (content),
      : (content, folder), 
      : (content),
      : !!synapses,
      : synapses ? .(synapses. || {}). : ,
      : ( fs.(skillMd)).,
      : !.(folder),
      : synapses?. === ,
      : synapses?.,
    });
  }

   skills;
}

Step 2: Categorize Skills

const CATEGORIES = {
  'cognitive': { emoji: '🧠', skills: ['cognitive-load', 'learning-psychology', 'appropriate-reliance', 'bootstrap-learning', 'meditation', 'meditation', 'knowledge-synthesis', 'global-knowledge'] },
  'engineering': { emoji: '🔧', skills: ['testing-strategies', 'refactoring-patterns', 'debugging-patterns', 'code-review', 'git-workflow', 'project-scaffolding', 'vscode-environment'] },
  'operations': { emoji: '🚨', skills: ['error-recovery-patterns', 'root-cause-analysis', 'incident-response', 'release-preflight'] },
  'security': { emoji: '🔐', skills: ['privacy-responsible-ai', 'microsoft-sfi'] },
  'documentation': { emoji: '📝', skills: ['academic-research', 'markdown-mermaid', 'lint-clean-markdown', 'ascii-art-alignment', 'llm-model-selection'] },
  'visual': { emoji: , : [, ] },
  : { : , : [, , , ] },
  : { : , : [, ] },
  : { : , : [, ] },
  : { : , : [] },  
};

Step 3: Generate Mermaid Diagram (High Fidelity)

The diagram generator must produce output matching the baseline catalog's richness.

Connection Schema in synapses.json

interface Connection {
  target: string;           // Target skill name
  type: string;             // enables, applies, extends, complements, triggers, curates
  strength: number;         // 0.0-1.0
  bidirectional?: boolean;  // true = <--> arrow
  weak?: boolean;           // true = -.-> dashed arrow
}

Arrow Types

Condition	Arrow	Meaning
bidirectional: true	<-->	Mutual reinforcement
weak: true OR strength < 0.5	-.->	Optional/weak link
Default	-->	Direct dependency

Multi-Target Syntax

When a skill connects to multiple targets, use Mermaid's multi-target syntax:

SCG --> MM & AH & KS

Not individual lines (reduces diagram clutter).

function generateNetworkDiagram(skills: SkillInfo[]): string {
  const lines: string[] = [
    '```mermaid',
    "%%{init: {'theme': 'base', 'themeVariables': { 'lineColor': '#666', 'primaryColor': '#e8f4f8', 'primaryBorderColor': '#0969da'}}}%%",
    'flowchart LR',
  ];

  // Group by category
  for (const [category, config] of Object.entries(CATEGORIES)) {
    const categorySkills = skills.filter(s => config.skills.includes(s.name) || (category === 'user' && s.isUserCreated));
    if (categorySkills.length === 0) continue;

    lines.push(`    subgraph ${capitalize(category)}["${config.emoji} ${capitalize(category)}"]`);
    for (const skill of categorySkills) {
      const abbrev = toAbbreviation(skill.name);
      lines.push(`        ${abbrev}[${skill.name}]`);
    }
    lines.push();
  }

  
   connectionGroups =  <, { : [], :  }>();

   ( skill  skills) {
     (!skill.) ;
     synapses = (skill.);
     connections = (synapses.);

     ( conn  connections) {
       sourceAbbrev = (skill.);
       targetAbbrev = (conn.);

      
       arrow = ;
       (conn.) {
        arrow = ;
      }   (conn. || (conn. && conn. < )) {
        arrow = ;
      }

      
       key = ;
       (!connectionGroups.(key)) {
        connectionGroups.(key, { : [], arrow });
      }
      connectionGroups.(key)!..(targetAbbrev);
    }
  }

  
   ( [key, group]  connectionGroups) {
     source = key.()[];
     (group.. === ) {
      lines.();
    }  {
      
      lines.();
    }
  }

  
  lines.();
  lines.();
  lines.();
  lines.();
  lines.();
  lines.();
  lines.();
  lines.();
  lines.();
  lines.();
  lines.();
  lines.();
  lines.();

  
   masterSkills = skills.( s. === ).( (s.));
   vscodeSkills = skills.( s. === ).( (s.));
   m365Skills = skills.( s. === ).( (s.));
   inheritableSkills = skills.( s. ===  && !s.).( (s.));
   userSkills = skills.( s.).( (s.));
   tempSkills = skills.( s.).( (s.));
   staleSkills = skills.( s.).( (s.));

  
   (masterSkills. > ) lines.();
   (vscodeSkills. > ) lines.();
   (m365Skills. > ) lines.();
   (inheritableSkills. > ) lines.();
   (userSkills. > ) lines.();
   (tempSkills. > ) lines.();
   (staleSkills. > ) lines.();

  lines.();

   lines.();
}


 (): [] {
   (.(connections)) {
     connections;
  }
  
   .(connections).( ({
    target,
    : data. || data. || ,
    : data. || data. || ,
    : data. || ,
    : data. || ,
  }));
}

Diagram Legend

Include this legend in generated catalogs:

### Legend

| Color | Inheritance |
| ----- | ----------- |
| 🟨 Yellow | Master-only |
| 🟦 Blue | VS Code heir |
| 🟩 Green | M365 heir |
| 🟪 Purple (dashed) | Temporary |
| 🧊 Cyan | Inheritable |

| Border | Meaning |
| ------ | ------- |
| ┅ Dashed | Staleness-prone or temporary |
| ── Solid | Standard skill |

| Arrow | Meaning |
| ----- | ------- |
| → Solid | Strong connection (weight > 0.7) |
| ⇢ Dashed | Weak connection (weight ≤ 0.7) |

Step 4: Generate Full Catalog

async function generateSkillCatalog(rootPath: string): Promise<string> {
  const skillsPath = path.join(rootPath, '.github', 'skills');
  const skills = await scanSkills(skillsPath);

  const systemSkills = skills.filter(s => !s.isUserCreated);
  const userSkills = skills.filter(s => s.isUserCreated);

  const catalog = `# My Alex Skills

> Generated: ${new Date().toISOString().split('T')[0]}
> Total Skills: ${skills.length} (${systemSkills.length} system, ${userSkills.length} user-created)

## Summary

| Category | Count |
| -------- | ----- |
${generateCategorySummary(skills)}

## Skills by Category

${generateSkillTables(skills)}

## Network Diagram

${generateNetworkDiagram(skills)}

${userSkills.length > 0 ? generateUserSkillsSection(userSkills) : ''}

  return catalog;
}

VS Code Integration

Command: Alex: Show Skill Catalog

vscode.commands.registerCommand('alex.showSkillCatalog', async () => {
  const rootPath = getWorkspaceRoot();
  const catalog = await generateSkillCatalog(rootPath);

  // Create virtual document
  const uri = vscode.Uri.parse('alex-catalog://skills/catalog.md');
  const doc = await vscode.workspace.openTextDocument(uri);
  await vscode.window.showTextDocument(doc, { preview: true });

  // Or save to file
  const catalogPath = path.join(rootPath, '.github', 'SKILL-CATALOG.md');
  await fs.writeFile(catalogPath, catalog);

  vscode.window.showInformationMessage(
    `Skill catalog generated with ${skills.length} skills`,
    'Open Catalog'
  ).then(choice => {
    if (choice === 'Open Catalog') {
      vscode.commands.executeCommand('markdown.showPreview', vscode.Uri.file(catalogPath));
    }
  });
});

Post-Migration Hook

// In migration completion
async function showPostMigrationCatalog(rootPath: string, migrationReport: MigrationReport) {
  const catalog = await generateSkillCatalog(rootPath);

  // Add migration-specific header
  const header = `# 🎉 Migration Complete!

## What Was Migrated

- **Skills restored:** ${migrationReport.skills.length}
- **Domain knowledge:** ${migrationReport.dk.length} files
- **User profile:** ${migrationReport.profileRestored ? '✅' : '❌'}

`;

  const fullCatalog = header + catalog;
  await showCatalogDocument(fullCatalog);
}

User-Created Skills Tracking

Identifying User Skills

A skill is user-created if:

1. Not in the SYSTEM_SKILLS list (shipped with extension)
2. Or has "userCreated": true in synapses.json
3. Or was created after initial installation (compare to manifest)

Learning Progress Metrics

interface LearningProgress {
  totalSkills: number;
  systemSkills: number;
  userSkills: number;
  skillsWithConnections: number;
  totalConnections: number;
  mostConnectedSkill: string;
  recentlyUsedSkills: string[];  // From episodic records
  suggestedNextSkills: string[]; // Based on current connections
}

---

Output Locations

Trigger	Output
Command	Preview in VS Code
Slash command	Chat response
Post-migration	Modal + saved file
/skills	Inline in chat
