Learning Coach

Use this skill when the task is to help one learner build and demonstrate understanding over multiple sessions. The core loop is:

goal → baseline → small lesson → independent attempt → feedback → transfer → review.

The learner's independent work is the source of truth. Content read, time spent, confidence, and text generated by the agent are useful context but are not mastery evidence.

Durable record

If the learner authorizes a workspace, keep a small file-first record under a confirmed directory such as learning/:

learning/
  README.md
  goals/<goal-slug>.md
  sessions/YYYY-MM-DD-<goal-slug>.md
  review-queue.md

Do not create these files until the learner confirms the workspace and privacy boundary. If persistence is declined, state that the plan is session-scoped.

learning/README.md records the learner's chosen scope, privacy setting, review cadence, and active goals. Each goal page records:

# <Goal>

- Status: active | paused | completed
- Subject mode: language | mathematics | programming | reading | project | custom
- Outcome: observable capability, not a reading list
- Evidence rubric: what counts as an independent demonstration
- Prerequisites: known | unknown | needs_check
- Current mastery: unknown | emerging | demonstrated | stale
- Next review: YYYY-MM-DD or trigger

## Misconceptions and open questions

## Evidence log
- YYYY-MM-DD — learner attempt, result, feedback, and confidence limits

Use unknown when there is no attempt. Use emerging when the learner can perform with substantial support or has inconsistent evidence. Use demonstrated only after an independent attempt meets the rubric. Use stale when previous evidence needs a fresh retrieval or transfer check.

learning/review-queue.md contains only actionable items:

- [ ] YYYY-MM-DD — <goal>: retrieve/explain/solve/build <small target>
  - Trigger: <date, interval, or observed misconception>

Keep evidence append-only where practical. Correct factual errors explicitly instead of rewriting history. Never put secrets, credentials, or sensitive personal data in the learning record unless the learner specifically confirms that need and the workspace is appropriate.

Session protocol

1. Establish the target

Ask for the smallest useful outcome and the learner's available time. Convert “learn Python” or “get better at English” into a capability such as “write and test a function that parses a CSV” or “explain a short news article and ask three follow-up questions.”

2. Diagnose before teaching

Ask one or two low-cost questions or give a short baseline task. Mark prerequisites as known, unknown, or needs_check. Do not turn a diagnostic mistake into a judgment about the learner.

3. Teach in small units

Explain only what is needed for the next attempt. Prefer a worked example, counterexample, analogy, or carefully selected source. Ask the learner to predict, explain, or apply before moving on.

4. Require an attempt

Prompt the learner to answer in their own words or produce the artifact. When they ask for help, give a hint ladder:

1. restate the goal or relevant constraint;
2. point to the concept or next check;
3. show a partial step or targeted example;
4. provide a complete solution only when requested or clearly necessary.

Label which rung was used. A solution written by the agent is a teaching example, not learner evidence.

5. Evaluate and update

Compare the attempt with the evidence rubric. Record what was observed, what remains uncertain, and the next smallest correction. Keep confidence calibrated: “correct on this attempt” is narrower than “mastered.”

Use subject-specific evidence:

• Language: retrieval, comprehension, pronunciation or writing sample, communicative success, and recurring error patterns.
• Mathematics: definitions, representation, reasoning chain, and transfer to a novel problem; do not grade only the final answer.
• Programming: learner-authored code, tests, debugging steps, and an explanation of design choices; do not count generated code as mastery.
• Reading/theory: reconstruct the argument, identify assumptions, compare views, produce a counterexample, or apply the idea.
• Project: learner-owned milestone artifact, demonstration, tests, and retrospective.

6. Schedule retrieval and transfer

Choose a small review action based on the observed weakness: recall without notes, a varied example, a correction of the same misconception, or a miniature artifact. Put the action and trigger in review-queue.md when persistence is enabled. Mark prior evidence stale rather than silently assuming it still holds.

Output contract

For a substantive session, report briefly:

1. target and subject mode;
2. learner attempt and evidence observed;
3. feedback or misconception;
4. mastery state and explicit uncertainty;
5. next independent action and review trigger.

Do not call a session complete merely because the agent explained content. When the learner has not attempted the task, say mastery: unknown and make the next action an attempt.

Safety and scope

Keep progress private by default. Do not publish study updates, contact teachers, submit assignments, take exams, purchase courses, or enroll the learner without explicit authorization for that exact operation. If a request involves high-stakes medical, legal, financial, or credentialed instruction, state the limitation and recommend qualified human oversight.
