Feature: Agent Cost Advisor Skill - Help users discover cost-optimized agents

[shakestzd]

Problem

Users unknowingly use expensive general-purpose agents when cost-optimized SlashSense agents exist, wasting 82%+ on execution costs.

Real Example: DocuColab workflow spent $1.40 using general-purpose agents instead of $0.25 using parallel-task-executor agents.

Impact

• 💰 Cost: 82% waste per parallel workflow
• 🎯 Discovery: Users don't know specialized agents exist
• 📊 Visibility: No cost preview before spawning agents

Root Cause

1. No agent discovery UI
2. No intelligent suggestions when spawning agents
3. Missing cost preview
4. Documentation not surfaced in-context

Proposed Solution

Create agent-cost-advisor skill that:

1. Intercepts Task tool usage
2. Analyzes task requirements
3. Matches to available SlashSense agents
4. Shows cost comparison
5. Gets user confirmation

Example UX

User: "Create 5 parallel tasks"

SlashSense (auto-suggests):
┌─────────────────────────────────────────────┐
│ 🎯 Recommended: parallel-task-executor      │
│ Cost: $0.20 (5 × $0.04)                     │
│ Speed: 5-10s total                          │
│                                              │
│ Alternative: general-purpose                │
│ Cost: $1.35 (5 × $0.27) - 85% more expensive│
│ Speed: 15-25s total                         │
└─────────────────────────────────────────────┘

Which do you prefer?

Implementation

1. Create .claude/skills/agent-cost-advisor.md
2. Add trigger patterns for Task tool usage
3. Query available SlashSense agents
4. Calculate costs for each option
5. Present recommendation with cost comparison

Acceptance Criteria

• Skill activates before Task tool execution
• Shows cost comparison for all relevant agents
• Recommends optimal agent type
• Gets user confirmation
• Tracks cost savings achieved

Estimated Effort

6-8 hours

ROI

• Saves $1.15 per workflow
• Annual savings: $1,380 (for 1,200 workflows/year)
