Claude Code introduces skill stacking
Claude Code (starting in version 2.1.199) now supports "skill stacking," which lets developers load up to five leading slash-command skills at the beginning of their input. The skills are loaded from left to right, and the parser stops stacking at the first token that does not start with a slash, meaning that subsequent skills placed later in the command will not be loaded.
Hot Take: Skill stacking is a powerful step toward modular Agentic workflows, but the strict left-to-right, consecutive prefix restriction is a rigid UX constraint that could lead to user error.
* **Streamlined Workflows:** Developers can invoke multiple distinct tools, instructions, or configurations in a single turn, improving agent orchestration efficiency.
* **Deterministic Execution:** Loading skills strictly from left to right makes initialization dependencies predictable.
* **Fragile Parsing:** Stacking stops at the first non-slash token, meaning standard prompting mixed with skills (like `/skill-a do X /skill-b`) will fail to load the latter skills.
