Practical AI and Prompt Workflows

Like Duolingo, but for Practical AI and Prompt Workflows. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

For the part of you with thirty open tabs that never became anything.

75 levels across 9 sections, about 150 minutes end to end, roughly 30 days at five minutes a day. It moves through Elevating Everyday Prompting; Precision Prompt Engineering; Under the Hood: Tokens, Context, and Sampling; Real-World Transformation and Extraction; Chaining and Multi-Step Systems; Grounding AI in External Knowledge; Tool Use and Agentic Behaviors; Reliability, Security, and Evaluation; and Production Decisions: Cost, Latency, and Architecture. It assumes you already know the basics.

What you'll learn

Key ideas in Practical AI and Prompt Workflows

  • LLMs act as deterministic processors when given both explicit source data and a fixed output transformation rule.
  • Querying models as general oracles triggers ungrounded retrieval from training weights rather than provided text.
  • Restricting the model to operate strictly upon supplied text bounds the output and prevents made-up facts.
  • Delimiters like XML tags or triple backticks create a clear boundary between operational prompt commands and raw text.
  • Without structural wrappers, instructional phrases embedded inside raw data can hijack the prompt's intended task.
  • Clear demarcation prevents context bleed where data is accidentally parsed as meta-instructions.
  • Instructing the model to ask diagnostic questions first exposes unstated constraints before drafting begins.
  • Answering targeted clarifying questions sequentially provides the missing context the LLM needs.
  • Final synthesis occurs only after all diagnostic requirements have been elicited and confirmed.
  • Enforcing an explicit output schema forces the model to normalize and categorize unstructured input data.
  • Targeted data schemas like JSON or markdown tables eliminate conversational fluff and ensure parsing consistency.
  • Specifying the target audience calibrates technical depth, tone, and assumed domain vocabulary immediately.
  • Operational bounds like length limits, banned words, and exact formats prevent iterative formatting tweaks.
  • Defining the evaluation criteria upfront lets the model filter its own draft before returning the response.
  • Role prompts shift the model's vocabulary distribution and tone toward a technical niche.
  • Role prompts cannot unlock reasoning power or eliminate underlying knowledge gaps.
