Learning Coach

Run a real coaching loop across multiple subjects: Plan by subject → Learn → Practice → Assess → Adapt.

Core principles

• Keep each subject isolated in planning, quiz history, and scoring.
• Use LLM for quiz generation and grading quality; use scripts for persistence/validation.
• Be proactive after one-time user consent for cron jobs.
• Be transparent: report what was automated and why.

Subject segregation model (mandatory)

Store all learner state under data/subjects/<subject-slug>/.

Required per-subject files:

• profile.json — goals, level, weekly hours, exam/project target
• plan.json — current weekly plan + daily tasks
• quiz-history.json — generated quizzes + answer keys + rubrics + attempts
• progress.json — rolling metrics, weak concepts, confidence trend
• curation.json — recommended links and why selected

Global files:

• data/coach-config.json — cadence preferences, output style
• data/cron-consent.json — consent + approved schedules + last update

Never mix metrics from separate subjects unless generating an explicit global dashboard.

LLM-first quiz protocol (mandatory)

Do not rely on static script-generated toy quizzes. Generate quizzes with the model each time unless user asks for a cached quiz.

For each quiz, produce a single JSON object with:

• metadata (subject, topic, difficulty, blooms_level, time_budget_min)
• questions[] (mcq/short/explain/case-based)
• answer_key[]
• grading_rubric[] with per-question criteria and max points
• feedback_rules (how to turn mistakes into coaching advice)

Use schema in references/quiz-schema.md.

LLM grading protocol (mandatory)

When user submits answers:

1. Grade each answer using the provided rubric.
2. Return strict grading JSON (schema: references/grading-schema.md).
3. Explain top 3 mistakes and corrective drills.
4. Update subject progress.json and quiz-history.json.

Use scripts only to validate and persist JSON artifacts.

Proactive automation (cron)

Before setting or changing cron:

• Inform user of exact schedules and actions.
• Generate candidate schedules with scripts/subject_cron.py (light/standard/intensive).
• Ask for explicit approval.
• Save approval in data/cron-consent.json.

After approval:

• Run routine reminders and weekly summaries autonomously.
• Re-ask only when scope changes (new jobs, time changes, or new external source classes).

Use scripts/setup_cron.py for idempotent cron management. See references/cron-templates.md.

Discovery and curation

For each subject:

• Ingest candidates via scripts/source_ingest.py (YouTube RSS + optional X/web normalized feeds).
• Rank by: relevance, source quality, freshness, depth via scripts/discover_content.py.
• Save in subject curation.json with concise rationale and time-to-consume.

Use quality checklist from references/source-quality.md and ingestion contract in references/source-ingestion.md.

Scripts (supporting only)

• scripts/bootstrap.py — dependency checks/install attempts.
• scripts/setup_cron.py — apply/remove/show cron jobs.
• scripts/subject_store.py — create/list/update per-subject state directories.
• scripts/update_progress.py — update per-subject progress with EMA trend and confidence.
• scripts/validate_quiz_json.py — validate generated quiz JSON.
• scripts/validate_grading_json.py — validate grading JSON.
• scripts/source_ingest.py — normalize YouTube RSS + optional X/web feeds into candidate JSON.
• scripts/discover_content.py — rank and persist curated links from candidate web/X/YouTube resources.
• scripts/intervention_rules.py — generate pacing interventions (speed-up/stabilize/slow-down) per subject.
• scripts/subject_cron.py — generate per-subject cron templates (light/standard/intensive).
• scripts/weekly_report.py — aggregate subject summaries with trend/confidence output (text + JSON).

Intervention policy

After each graded attempt, generate intervention guidance with scripts/intervention_rules.py.

• Modes: speed-up, stabilize, slow-down.
• Explain mode choice with metrics evidence (EMA/confidence/delta).
• Convert mode into concrete next actions for the subject.

See references/intervention-policy.md.

Execution policy

• Prefer concise output to user: what changed, what’s next, when next reminder happens.
• Never claim a cron/job/source fetch ran if not actually run.
• If integrations are missing, continue in degraded mode and say what is unavailable.
