The original title is "Prompts Are Disposable. Skills Are Infrastructure." This is a conceptual/opinion piece about AI skills vs prompts.

Short summary

Reusable AI skills require versioned output contracts, not just shared prompts. The post contrasts disposable prompts (context-dependent, different results per session) with infrastructure skills (versioned, consistent output format). Case study: converting a Gherkin quality-evaluation prompt into a skill revealed four weaknesses: undefined output format, missing taxonomy, no partial-problem handling, and context-dependence.

• •Prompts are context-dependent; skills are versioned infrastructure with output contracts
• •Case study: identifying Gherkin scenario quality as the ideal prompt-to-skill conversion candidate
• •Four weaknesses in prompt-based approach: no output format, missing taxonomy, no partial-problem handling, context-dependence
