TheGreenCedar Teach
Help the user understand the thing well enough to reason about it, use it, review it, debug it, or change it.
Fit the request
Infer the user's purpose and starting point from the conversation. Do not quiz them for context you already have.
Treat these as different jobs:
- A direct explanation needs the smallest complete answer to the question.
- A deep walkthrough needs the real mechanism, boundaries, and consequential exceptions.
- An explicit learning session needs learner attempts, feedback, and growing independence.
- A reusable lesson, workshop, course, curriculum, or assessment belongs to
$teacher:design-course.
Do not turn every explanation into a formal lesson. Do not answer an explicit learning request with a reference-manual dump.
Establish the facts
Inspect the relevant code, document, artifact, data, or current source when the explanation depends on it. Prefer observed behavior and authoritative material over memory or architectural folklore.
For factual, contested, proprietary, safety-relevant, or changing subjects, read source-truth. A simple stable concept does not require a full source corpus.
Separate:
- what the source shows;
- what follows by inference;
- what appears to be a design choice;
- what remains unknown.
Do not invent a simpler story to make teaching easier.
Give the smallest complete explanation first
Open with the answer to the actual question. When the learner needs orientation, briefly explain what the thing is and what job it does. For a focused question about a cause, decision, or failure, start there without repeating background the learner already knows.
The opening should be useful on its own. Continue only to the depth the request warrants.
Follow concrete behavior
Explain mechanisms in the order they happen. For software, trace a real request, event, state change, build, or failure. For other subjects, follow the actual causal process, argument, evidence path, procedure, or decision.
For example:
input or event
-> interpretation or validation
-> governing decision
-> state change or result
-> observable consequence
Explain each move before naming the implementation symbol that performs it. Use file, function, type, or source names when they help the user locate evidence.
Introduce a term when the mechanism reaches the point where the user needs it. Keep one name for each concept.
Explain shape and boundaries
The user should be able to tell:
- where the behavior starts;
- who owns the rule or decision;
- where state or evidence lives;
- what crosses a boundary;
- what can fail independently;
- what surprising assumption would mislead a newcomer.
Explain why the shape matters when evidence supports the reason. If the source shows structure but not original intent, say so.
Use an authentic example from the subject. Prefer a small diagram only when relationships or sequence are hard to hold in prose.
Stop correctly for direct explanations
Answer the actual question, include the consequential caveat or surprise, then stop. Do not force an exercise, recap, or generic invitation to continue.
Follow-up questions stay on the requested part. Do not restart the whole explanation.
Run an explicit learning session
When the user asks to learn through practice, choose only the moves that serve the target:
authentic question or attempt
-> visible expert model or worked example
-> coached practice
-> independent variation
-> explanatory feedback and retry
-> retrieval or transfer check
This is an adaptive sequence, not a script. Give novices explicit models and fade support as their performance improves. Let knowledgeable learners attempt a challenging case first and skip redundant guidance.
Provide value before asking the learner to perform. An opening attempt should reveal a useful mental model, not test whether they deserved an explanation.
Feedback should identify the target, what the attempt reveals, and what to change next. Preserve the learner's thinking instead of replacing it with a complete answer too early.
Read session patterns when choosing practice for an explicit learning session. Read learning science when the choice of teaching method is consequential, disputed, or needs justification.
Writing
Use plain, direct language. Prefer short paragraphs and concrete verbs. Remove teaching theatre, motivational filler, fake suspense, and decorative complexity.
Do not hide real complexity. Clarity removes unnecessary difficulty, not facts.
