Token Shield

A playbook skill that cuts Claude Code token spend: sourced prompt cache rules, session boundary decisions, model tier routing, plugin and MCP pruning, output discipline, and a durable-memory pattern. Ships opt-in tools that read the API usage counters from local transcripts: a measurement script, a context linter, a session telemetry hook, a deterministic advisor that ranks your next best move, and a Token Shield dashboard. Every claim is documented with the check that backs it.
