lazy-agent-loader（惰性 Agent 加载器）

Lazy Agent Loader

Priority: HIGH - Load agents on-demand Version: 1.0.0

Purpose

Reduce token usage by:

1. Loading only agent summaries initially (~50 tokens each)
2. Loading full definition only when agent is activated
3. Caching loaded agents in session state

Agent Index (Summaries Only)

Loading Strategy

Initial Load (~1200 tokens)

1. Load this index file (agent_index)
2. DO NOT load individual agent files
3. Use index for agent detection scoring

On Agent Selection (~500-2000 tokens per agent)

1. Agent scores ≥80 (PRIMARY) → Load full definition
2. Agent scores 50-79 (SECONDARY) → Load summary only
3. Agent scores <50 (OPTIONAL) → Don't load

Full Definition Location

agents/[agent-id].md

Loading Commands

Load Single Agent

# Load full agent definition
cat agents/mobile-react-native.md

Load Agent Summary

agent_summary{id,role,focus}:
  mobile-react-native,Senior React Native Developer,Expo/RN mobile apps with TypeScript

Integration with Agent Detector

Step 1: Score agents using agent_index keywords
Step 2: Identify PRIMARY agent(s) with score ≥80
Step 3: Load ONLY PRIMARY agent full definitions
Step 4: For SECONDARY agents, use summary from index

Token Savings

comparison[4]{scenario,without_lazy,with_lazy,savings}:
  Initial load (24 agents),~48000,~1200,97.5%
  Single agent task,~48000,~2700,94.4%
  Dual agent task,~48000,~4200,91.3%
  Full stack (3 agents),~48000,~5700,88.1%

Cache Strategy

Session Cache

Loaded agents are cached in conversation context.
If agent already loaded, skip re-loading.
Track loaded agents: loaded_agents[]: mobile-react-native,qa-automation

Force Reload

User: "reload agent mobile-react-native"
→ Clear cache for agent
→ Re-read full definition

Example Flow

User: "Create a React Native screen for login"

1. Agent Detector scores all agents using keywords from agent_index
   - mobile-react-native: +60 (react-native) +20 (context) = 80 ✅ PRIMARY
   - ui-designer: +35 (screen/login implies UI) → OPTIONAL

2. Lazy Loader activates:
   - Load: agents/mobile-react-native.md (~1500 tokens)
   - Skip: ui-designer (score < 50)

3. Context loaded:
   - Agent index: ~1200 tokens
   - mobile-react-native full: ~1500 tokens
   - Total: ~2700 tokens (vs ~48000 without lazy loading)

Agent Categories

categories[4]{name,count,when_to_load}:
  dev,11,When code/implementation requested
  quality,3,When review/test/design requested
  ops,5,When deploy/integrate/notify requested
  infra,5,Usually auto-loaded by system

Note: This skill is automatically used by agent-detector for optimized loading.
