If you have doubts on when to use AI skills and when you should rather prefer using a script this article will clear your doubts
TLDR
Use this quick flow to decide whether a skill, a script, or a hybrid makes the most sense for your automation.

- Use scripts for deterministic work like data transforms and reproducible automations.
- Use a skill when the LLM needs to interpret unstructured input in a loop.
- Use a hybrid when one interpretive step sits inside an otherwise deterministic process.
When to use a skill
- You need an LLM to interpret unstructured data (natural language, images, multimodal inputs) inside a process that runs in a feedback loop.
- Logic depends on nuances that are hard to capture in code: agentic scraping, screenshot or log analysis, context-dependent decisions.
- You must teach the LLM to produce a specific output (markdown with guidelines, code with a house style, reports, presentations, reviews) based on interpreted inputs.
- You can attach references, assets, or helper scripts that the skill uses for the deterministic parts, all triggered from chat.
When to use a script
- The process is deterministic and needs no interpretation.
- You want the result to avoid any LLM dependency at runtime (an agent can generate the script, but it should stand alone afterward).
- You care about exact reproducibility and easy debugging.
When to use a hybrid approach
- The process is mostly deterministic but needs a one-off interpretation step that is not in a feedback loop.
- A script starts the flow; the LLM performs that single interpretive step and hands control back to the deterministic path.
- Handy for light human-like validation or disambiguating inputs before continuing with strict logic.
Reminder
- A skill can orchestrate scripts and support assets to cover the deterministic parts. The skill remains the entrypoint whenever interpretation in the loop is required.
