Claude Cost Optimizer

Claude Cost Optimizer is a Claude Code skill that cuts your token spend with copy-paste configs and proven strategies instead of vague advice. It claims 30-60% savings on Claude Code costs in normal use, with a 'strict' mode in its cost-mode skill targeting 60-70% output reduction — and the repo documents one real case hitting $114.18/month, a 61% cut. The core is a cost-mode skill that strips unnecessary content from responses, suggests cheaper models for simple tasks, recommends CLI tools instead of burning tokens, adds session-awareness reminders, and prefers diffs over full file rewrites. Around it sits a full toolkit: context optimization (.claudeignore and CLAUDE.md management), model-selection guidance for when to reach for Opus vs Sonnet vs Haiku, workflow patterns like plan mode and subagents, a team-budgeting framework, MCP and agent cost analysis, prompt-caching guidance, and CLI tools to actually measure your spend. Install it into Claude Code via the plugin marketplace, or into any multi-agent environment with 'npx skills add Sagargupta16/claude-cost-optimizer'. It's MIT-licensed.
