Token Optimization Implementation Summary

Date: 2025-10-04
Status: ✅ COMPLETE
Expected Token Savings: 60-75%

✅ All Priorities Implemented

Priority 1: Conditional Research ⭐ HIGHEST ROI

Expected Impact: 50-70% reduction in research tokens

Changes Made:

  • ✅ agent/architect_full.md - Added conditional research logic with skip/only criteria
  • ✅ command/auto_feature.md - Added research scope analysis before web search
  • ✅ command/feature_decompose.md - Skip re-research of existing architecture findings
  • ✅ command/auto_plan.md - Reuse feature architecture tech decisions, skip broad research

Key Features:

  • Architects now check if tech is already specified before researching
  • Skip research for simple/common patterns (REST, JWT, CRUD, etc.)
  • Only research novel tech, complex decisions, or emerging patterns
  • Focus research on specific unknowns, not general best practices

Priority 2: Optional Integration Analysis ⭐ HIGHEST ROI

Expected Impact: 30% reduction for Phase 1 tasks

Changes Made:

  • ✅ command/auto_plan.md Phase 1.5 - Added conditional execution logic
  • ✅ Added Step 2.5: Evaluate integration analysis need
  • ✅ Skip integration analysis for Phase 1 tasks with no dependencies

Key Features:

  • Integration analysis only runs when prior tasks exist
  • Saves entire architect spawn for Phase 1 tasks
  • Logs decision for transparency

Priority 3: Inline Context Passing ⭐ HIGH ROI

Expected Impact: 40% reduction in context loading

Changes Made:

  • ✅ command/auto_plan.md - Added Phase 0.5: Extract Essential Context
  • ✅ Updated all 6 agent spawn prompts with inline context
  • ✅ Context extracted once, passed to all agents

Key Features:

  • New Phase 0.5 extracts task context (300 tokens) and feature arch summary (400 tokens)
  • All agents receive inline context instead of re-reading files
  • Agents can optionally read full files if more detail needed
  • Reduces redundant file reads from 6+ times to 1 time

Updated Agent Spawns:

  1. Phase 1: Architect (architectural analysis)
  2. Phase 1.5: Architect (integration analysis)
  3. Phase 2: Planner (implementation planning)
  4. Phase 3: Plan reviewer (unified review)
  5. Phase 4: Architect (refinement)
  6. Phase 4: Planner (refinement)

Priority 4: Architecture File Restructuring ⭐ MEDIUM ROI

Expected Impact: 35% reduction in context loading

Changes Made:

  • ✅ command/auto_feature.md - Modified to create TWO architecture files
  • ✅ command/feature_decompose.md - Read essential arch only
  • ✅ command/auto_plan.md Phase 0.5 - Extract from essential arch only
  • ✅ Created templates/arch_essential.md template
  • ✅ Created templates/arch_research.md template
  • ✅ Created .cache/arch_migration.md migration guide

Key Features:

  • Essential architecture file (arch_{id}.md) - max 1500 tokens

    • Key decisions (3-5)
    • Tech stack (table)
    • Components (high-level)
    • Integration strategy
    • Critical constraints
    • Decomposition guidance

  • Research file (arch_{id}_research.md) - optional reference

    • Detailed research findings
    • Options considered
    • Deep dive analysis
    • References

Templates Created:

  • templates/arch_essential.md - Structured template for essential decisions
  • templates/arch_research.md - Template for detailed research
  • .cache/arch_migration.md - Guide for migrating existing files

Priority 5: Review Consolidation ⭐ MEDIUM ROI

Expected Impact: 25% reduction in review phase

Changes Made:

  • ✅ Created agent/plan_reviewer.md - New unified review agent
  • ✅ command/auto_plan.md - Replaced Phase 3a and 3b with Phase 3
  • ✅ Updated Phase 4 refinement to use unified review
  • ✅ Updated Phase 5 final report metrics

Key Features:

  • Single review agent evaluates both implementation (50%) and architecture (50%)
  • One agent spawn instead of two sequential spawns
  • Single compliance score instead of averaging two scores
  • Faster review with same quality
  • Refinement phase spawns only needed agents (architect OR planner, not both)

Phase 3 Changes:

  • Old: Phase 3a (implementation review) + Phase 3b (architectural review) = 2 spawns
  • New: Phase 3 (unified review) = 1 spawn
  • Savings: 1 agent spawn + 1 context load per task

Token Savings Breakdown

Optimization Savings Impact Area
Conditional Research 50-70% Architect agent research
Optional Integration 30% Phase 1 tasks
Inline Context Passing 40% All agent spawns
Architecture Restructuring 35% Architecture file reads
Review Consolidation 25% Review phase
Total Estimated 60-75% Overall workflow

Example Workflow Token Usage

Before Optimization (4-Task Feature)

Feature Creation: ~5,200 tokens
Feature Decomposition: ~5,500 tokens  
Task Planning (×4): ~34,000 tokens
─────────────────────────────────
