Learn Prompt Engineering with Phoebe

Ask better. Ship better. Prompt engineering for 2026, both halves.

Two tracks, one running company. The 6-session leader track teaches executives, boards, and managers the thinking moves - how to ask the right question, judge the answer, and get AI ideas shipped. The 10-session builder track takes practitioners from core techniques to reasoning models, agents, evals, and prompt security. Built from the official Anthropic, OpenAI, Google, and DeepLearning.AI material - and honest about what changed since 2023.

The leader track 🀝 · for C-level, boards & managers · 6 x 45 min · no tech required

Prompting as delegation, not magic words. The thinking mode: ask the right question, think with the machine, judge what comes back, and work with your data and tech people to get ideas realised. Also a friendly on-ramp for LinkedIn readers.

The builder track πŸ› οΈ Β· for practitioners Β· 10 x 45 min Β· any model or API

For DA, DE, DS, and engineers. One running build - TriageBot, a support-ticket triage prompt system - hardened session by session: techniques, structured output, reasoning models, long context, agents, vendor deltas, evals, and security.

The 2026 map: where prompting fits now

Success criteria before prompts, prompting inside context engineering, and the model-class decision tree that rewrites 2023 advice.

🧱 Builder session 2

Core techniques

Clear and direct, delimiters and structure, templates with variables, few-shot examples, and the honest 2026 role of roles.

The foundation
πŸ“¦ Builder session 3

Output control

Format matching, schema-enforced structured output, verbosity control, and the prefill deprecation with its five migration patterns.

Structured output
πŸ€” Builder session 4

Reasoning: CoT to thinking models

The 2022 papers as lineage, the great inversion (no more "think step by step"), and effort parameters as the new dial.

The inversion
πŸ“š Builder session 5

Long context, grounding, caching

The placement wars between vendors, document tags and quote-grounding, RAG vs grounding, and cache-shaped prompt layout.

Context craft
πŸ€– Builder session 6

Chaining + agentic prompting

Prompt chains and self-correction, the three agentic reminders, eagerness calibration, and tool descriptions as the forgotten prompt.

Agents
βš–οΈ Builder session 7

Vendor deltas masterclass

Claude, GPT, and Gemini side by side: terminology, model-specific pages, the sampling-params history, and the portability checklist.

Cross-vendor
πŸ“ Builder session 8

Evals I: from vibes to numbers

Why looks-good-to-me fails, the grading taxonomy from exact match to LLM-judged, and your first eval harness with promptfoo.

Measurement
πŸ§ͺ Builder session 9

Evals II: judge, CI, agent evals

LLM-as-judge done properly, regression gates on every prompt change, and the router-skill-trajectory taxonomy for agents.

Quality gates
πŸ” Builder session 10

Security + production

Injection vs jailbreak, the lethal trifecta, why defense is architecture not wording, and prompts as versioned, gated code.

One company, both tracks. Every session works on Meridian Retail - a 2,000-person retailer with 80 stores whose exec team just got AI accounts and whose builders are shipping TriageBot, a support-ticket triage prompt system. Leaders take the COO's chair and learn to ask, judge, and sponsor; builders take the keyboard and harden TriageBot from a naive one-liner to a shipped, eval-gated, injection-tested system.
Honest about scope. Sessions distill the official material - Anthropic's prompting docs, interactive tutorial, and eval courses; OpenAI's prompting and reasoning guides; Google's prompting whitepaper and Gemini docs; the DeepLearning.AI short courses; OWASP and the key research papers. Vendor certificates, videos, and quizzes stay with their official sources. This field moves fast: content verified against live docs in July 2026, and worth a changelog check before delivery.
