Pattern-Based Skill Invocation - Implementation Verification

✅ Implementation Complete

Pattern-based skill invocation has been successfully implemented and tested.

🎯 Architecture Overview

User Message: "please /commit and /mr these changes"
        ↓
┌───────────────────────────────────────────────────────┐
│ Step 1: Pattern Detection (pattern-matcher.ts)       │
│ - Regex scan: /(?<![:\w])\/([a-z][a-z0-9-]{0,49})/  │
│ - Extract: [{ name: 'commit' }, { name: 'mr' }]      │
│ - Exclude built-ins: /help, /clear, etc.             │
│ - Deduplicate: /mr /mr → /mr                         │
└───────────────────────────────────────────────────────┘
        ↓
┌───────────────────────────────────────────────────────┐
│ Step 2: Load Skills (SkillManager.getSkillsByNames) │
│ - Discovery: Scan .codemie/skills/                   │
│ - Load SKILL.md: Parse metadata + content            │
│ - Build inventory: Scan for .md, .sh, .js, etc.      │
│ - Format: Create injection-ready content             │
└───────────────────────────────────────────────────────┘
        ↓
┌───────────────────────────────────────────────────────┐
│ Step 3: Inject SystemMessage (agent.chatStream)      │
│ - Create SystemMessage with skill content            │
│ - Include file inventory (paths only)                │
│ - Add to conversation history before user message    │
│ - Priority guidance for LLM                          │
└───────────────────────────────────────────────────────┘
        ↓
┌───────────────────────────────────────────────────────┐
│ Step 4: LLM Processing (with skills context)         │
│ - Receives: Skill guidance + file inventory          │
│ - Can use Read tool for on-demand file access        │
│ - Follows skill workflow and best practices          │

🧪 Test Results

Unit Tests (43 tests)

Pattern Matcher (33 tests) - All Passing ✅

  • Single pattern detection: /mr
  • Multiple patterns: /commit and /mr
  • Mid-sentence: ensure you can /commit this
  • Arguments: /commit -m "fix bug"
  • Built-in exclusions: /help, /clear, /exit, etc.
  • Name validation: lowercase, hyphens, numbers
  • Deduplication: /mr /mr → single pattern

Content Loader (10 tests) - All Passing ✅

  • Load skill with inventory
  • Handle missing directories
  • Exclude: hidden files, node_modules, SKILL.md
  • Include: .md, .sh, .js, .ts, .py, .json, .yaml
  • Subdirectory scanning
  • Alphabetical sorting
  • Permission error handling

Integration Tests (10 tests)

Pattern Invocation Flow - All Passing ✅

  1. Single skill injection
  2. Multiple skills (2+)
  3. Non-existent skills (graceful)
  4. Mixed valid/invalid
  5. Built-in exclusion
  6. Deduplication
  7. File inventory with subdirectories
  8. Pattern arguments
  9. Minimal skill (no files)
  10. Direct loading

Total: 53 new tests, 100% passing

📊 Live Demo Results

Test 1: Single Pattern

Input:  "please /commit these changes"
Output: ✅ Detected: commit
        ✅ Loaded: commit skill
        ✅ Inventory: 0 files

Test 2: Multiple Patterns

Input:  "please /commit and then /mr"
Output: ✅ Detected: commit, mr
        ✅ Loaded: commit, mr skills
        ✅ Inventory: 2 files (mr skill)

Test 3: Mid-Sentence Pattern

Input:  "ensure you can /mr this work"
Output: ✅ Detected: mr at position 15
        ✅ Arguments: "this work"
        ✅ Loaded: mr skill
        ✅ Content: 9290 chars injected

Test 4: Built-in Exclusion

Input:  "/help me with this"
Output: ✅ Detected: none (correctly excluded)

Test 5: Deduplication

Input:  "/mr and then /mr again"
Output: ✅ Detected: mr (deduplicated from 2 to 1)
        ✅ Pattern count: 1

🎯 Three-Tier Progressive Loading

Tier 1: Startup (Always Active)

  • Load: Skill metadata only (name, description)
  • Size: ~100 bytes per skill
  • Use: Display in codemie skill list

Tier 2: Pattern Detected (On /skill-name)

  • Load: Full SKILL.md + file inventory
  • Size: ~5-10KB per skill
  • Use: Inject as SystemMessage for LLM guidance

Tier 3: On-Demand (LLM uses Read tool)

  • Load: Specific reference files
  • Size: ~10KB per file
  • Use: LLM decides when to access additional context

Token Efficiency:

  • Without file inventory: 20KB upfront for all files
  • With file inventory: 5KB + 10KB only if needed = 15KB max
  • Savings: 25% reduction, more if files not accessed
