The summary Claude sees in its skill listing — used to decide when to auto-load this skill
Estimate the cost of a coding task before execution, with multi-model comparison.
Estimates token usage, costs across Haiku/Sonnet/Opus, complexity levels, and time for features by analyzing codebase files/lines via Glob/Read/Grep. Use for pre-implementation planning.
Optimizes Claude Code costs: track tokens and USD with /cost, route models (Haiku/Sonnet/Opus), reduce via /compact/grep/sub-agents, maximize prompt caching.
Enforces concise responses, smart model routing, and efficient workflows to reduce output tokens 40-70% and costs 30-60% while maintaining technical accuracy.

─────────────────────────────────────────────────────────────
Claude Haiku 4.5 $0.04 $0.20 $0.24
Claude Sonnet 4.6 $0.15 $0.75 $0.90 ← current
Claude Opus 4.6 $0.75 $3.75 $4.50
💡 Claude Haiku 4.5 would be 73% cheaper
