Understanding the learner

Record what happened precisely enough that another teacher can make the next decision. “Bad at math” is useless. “Cancelled x across addition, corrected it after comparing x(x+1) with x²+1” tells the next teacher what to check.

Read and write

For someone you already know, use the script beside this skill:

python3 skills/learner-tracking/scripts/learner_state.py init alex
python3 skills/learner-tracking/scripts/learner_state.py summary alex
python3 skills/learner-tracking/scripts/learner_state.py record alex --event session.json

init creates a blank learner profile (learners/<name>/state.json). It starts completely empty — do not guess or assume the user's background, or skill level. By default, profiles are saved in the repository's ignored learners/ directory. Pass --root <directory> to use a different folder (e.g., in automated tests). For the full schema and update rules, see references/evidence.md.

When enrolling a learner, the validated course plan is copied to learners/<id>/courses/<course-id>/course.json. The learner's state.json only stores a relative path, revision number, and fingerprint (hash) of the course plan rather than keeping a duplicate copy. If the course plan changes and its hash no longer matches state.json, future updates are blocked until the plan is reconciled. If you are working with an older record that has an embedded plan, run migrate-courses <id> once to convert it safely.

Never render lessons, viewer pages, or progress directly from a blueprint course.json. Always set up the learner first:

1. Identify the learner: If they provide a name, convert it to a lowercase folder name (e.g., alex). If they don't, proceed automatically as learner and say: "I'll save your progress under 'learner' — tell me a name anytime to make it yours." Never ask the user for a "learner ID".
2. Initialize and enroll: Run init followed by enroll --course <course.json>. Omitting the name defaults to learner.
3. Verify: Confirm that learners/<name>/courses/<course-id>/course.json exists before recording attempts, summarizing progress, or rendering views.

Course and memory categories

Read references/memory-categories.md when starting, resuming, enrolling, or finishing a course. Store a validated course with enroll <id> --course <course.json>. Use complete-course <id> --course-id <slug> when the learner finishes; the script produces a chapter-by-chapter curriculum with topic names, teachers, sources, assessments, and actual evidence.

Read references/adaptive-lifecycle.md to adapt in real time: record what the learner does, then tell the course skill to update the plan when a source fails or the learner is stuck.

Every recorded attempt or topic transition refreshes profile, course, topic, teaching-observation, and next-step memories. Update at meaningful evidence changes during the conversation, not only at the end of a course. On resumption, use earlier taught topics as explicit bridges into the next topic. Keep one folder per person, do not assume unrelated chats have shared memory.

Resolve every enrolled plan before changing learner state. If a referenced plan is missing or invalid, fail before recording a new attempt or profile change. Derived Markdown views may be rebuilt from valid state, they never override it.

Separate the kinds of knowledge

• Stated preference: “Use fewer analogies.” Store the wording and date, a current request overrides it.
• Observation: a specific answer, error, hint used, or successful transfer.
• Interpretation: a tentative explanation of the observation. Say “possibly confuses slope with height,” not “is a visual thinker.”
• Action: what the next teacher should try or ask.

Mark taught-but-untested concepts as exposed. Assisted success is practice. Independent success supports demonstrated understanding of that concept in that task. A later independent retrieval/transfer supports retention. None is a permanent trait or a guarantee of general mastery.

Review saved exercises before the next lesson

On completion or resumption, follow exercise-review.md. Load the current lesson, actual stored responses, original criteria, and assistance. Review checked answers as well as written work; an unsent browser draft is not evidence. Record each attempt through manage_interaction.py review-attempt, then record the lesson repair and continuation decision through review-lesson. A wrong answer is an observation: diagnose its cause and inspect the teaching before choosing the repair. Preserve old attempts and unresolved gaps.

Choose the next move

If a wrong answer could have several causes, use one contrast to distinguish them before labeling the gap. A new representation counts as helpful only when subsequent work improves, not because the learner says it looks nice.

Use recent evidence and task difficulty together. After a long gap, check recall briefly before choosing the pace. If the learner is correct but slow, distinguish fluency practice from a conceptual repair. Do not prescribe a fixed review interval as scientifically optimal, agree a date suited to the goal.

Keep the record small and honest

Save short evidence excerpts, not whole conversations. Do not store unrelated personal details, secrets, diagnoses, or guesses about intelligence. Keep records for different learners separate. Never copy example evidence into a real profile. Only report saved progress after a successful write. If saving fails, preserve the note in the response and say it was not saved.

Use profile <id> --file <json> to replace explicitly provided preferences/goals. Use retract <id> --event-id <id> to remove a mistaken event, then re-record a correction if needed. delete <id> is a state reset: it removes state and known derived memory views, while course workspaces, submissions, drafts, hints, questions, reviews, artifacts, and rendered pages remain. Do not describe that command as complete learner-data erasure. A full erasure needs a separately validated inventory and coordinated protection against concurrent course writes; the current CLI does not provide it. Preserve unrelated user files.
