Open field guide / learning + building + operating

AI Field Guide

This is where I turn what I learn while building with AI into guides, experiments, pitfalls and reusable patterns — always mapped back to Work With AI, Give AI Work and Run AI.

Cross-course field guide
What you'll learn

See how Prompt, Context, Harness, Loop and Graph Engineering fit into the three-course journey, and use the guide that matches the problem you actually have.

Bring / required

Nothing for the map. Bring a real task, repository or AI workflow when following a hands-on guide.

What you'll do

Start from the core programme or from the failure you are seeing, then use the relevant field guide, lab or future field note.

Take away

A clear mental model of where each engineering discipline belongs and a path from human-AI collaboration to delegated and operated AI systems.

One journey. Different engineering problems.

01 · Collaborate

Work With AI

AI works with me. Engineer the instruction and the reality available to the model.

02 · Delegate

Give AI Work

AI works for me. Make one delegated responsibility dependable, then make continuation controlled.

03 · Operate

Run AI

I operate AI I may depend on. Make coordination, authority, recovery and business outcomes explicit.

Field-guide map

Prompt → Context → Harness → Loop → Graph → Operate. This is a way to locate the problem, not a maturity checklist. Many useful tasks should stop at Prompt or Context. Many delegated jobs need a Harness but never need a Graph.

03 / Run AI

ENGINEER THE SYSTEM YOU MUST OPERATE.

When several responsibilities share state, branch, conflict, recover or affect the same business outcome, their relationships become an operating problem.

Evidence labels

Because this site records a real journey, every empirical claim should make clear what kind of evidence supports it.

LabelUse when
ObservedI directly saw it in my own build/run.
ReproducedI repeated it under documented conditions.
SimulatedIt happened in a classroom/test scenario, not production.
DesignedIt is a proposed architecture/pattern not yet run end-to-end.
ExternalAnother source reports it; cite source/version/date.
IllustrativeIt is invented only to explain a concept.
Evidence rule

Do not quietly turn a Designed pattern or Simulated exercise into a claim about observed production behavior.

One lab method across all five disciplines

The resource pack gives you artifacts and the Lead-to-Appointment lab gives you continuity. The Lab Method gives every future recording the same evidence spine.

Lab method

Baseline → Hypothesis → One intervention → Rerun → Measure → Break it → Conclude → Submit / keep.

It is not scientific theatre. It simply stops us from changing five things at once and then guessing which one mattered.

This is also my working notebook

The stable guides above are the current distilled view. The field guide should also preserve how that view was earned as I build and operate real systems.

TypeWhat it recordsHow it should change
GuideCurrent mental model, pattern, pitfalls, proof and when not to use it.Revise as understanding improves.
LabBaseline → hypothesis → one intervention → rerun → evidence.Keep reproducible.
Field noteA dated build, failure, surprise, fix and what I currently believe.Do not rewrite history; add a newer note when the view changes.
TeardownHow a real tool/runtime implements the same ideas.Update or date when the product changes.
RecordingThe live reasoning, mistakes and experiment.Layer it onto a useful written page; do not make the video the only explanation.
Journey rule

The polished guide can change. A dated field note should preserve what happened then. That lets 9order be both a useful reference and an honest record of the journey.

Field notes — the journey behind the guide

The stable guides show the current view. Field notes preserve the reasoning, mistakes and corrections that led there.

How a recorded field-guide lesson should work

  1. Failure: show the weak or broken version.
  2. Likely instinct: name the fix people usually try.
  3. Aha: replace one misleading mental model.
  4. Build: change one structural element.
  5. Rerun: compare against the baseline.
  6. Break it: remove the change or inject a counterexample.
  7. Common traps: show realistic bad implementations.
  8. Look out for: teach signals that the current design is reaching its limit.
  9. Prove it: define observable acceptance evidence.
  10. Keep: leave a copyable artifact.
  11. Next tension: expose the next unresolved problem.
Teaching rule

A recording without a reproducible failure and a pass test is a demonstration. The field guide should turn the recording into a lab someone can revisit later.

Architecture first. Framework second.

You do not need LangGraph, CrewAI or any particular agent framework to learn these disciplines. Frameworks are implementation choices. First understand intent, context, responsibility, state, verification, routing, authority and evidence.

The same field guide can later contain framework-specific labs and teardowns without turning the core concepts into product tutorials.
