The Workflow Tool's Prompt Footprint Dropped From 5.7k Tokens to 1k by Moving Its Reference into a Skill
2.1.248 shrank the Workflow tool description from about 5.7k tokens to about 1k by moving the script-writing reference into a bundled `workflow-authoring` skill that loads only when a workflow is actually being authored. That is roughly 4.7k tokens reclaimed from every single request in every session that has the tool enabled. It is a reusable pattern for anyone shipping custom tools: a large tool description is a per-turn tax, and a skill is a lazily loaded alternative.
