Cross-cutting: a pre-term profile informs Stage 0/1 design\n(`course-designer` reads `learner_profile`), pre-lesson results calibrate Stage 2\nbuilds (`lesson-builder`), and the Stage 4 weekly loop re-runs the cycle as the\ncohort moves. The professor knows the discipline and the students; this skill brings\ninstrument craft, aggregation honesty, and the discipline to say what a 5-item quiz\ncannot say.\n\n> **Prime rule — the privacy architecture:** the unit of analysis is the **cohort**.\n> The Course Passport receives aggregates only — distributions, prevalence\n> percentages, heterogeneity measures — written into `learner_profile` and shown to\n> the professor verbatim before writing. Raw data (named or identifiable rows) stays\n> in the professor's files: the skill works on it in-session, pseudonymizes where\n> feasible, and never writes any individual-level fact to the passport or any state\n> file. \"Which students need help?\" is not this skill's question — that routes to\n> `student-mentor`, which the professor initiates with the evidence in hand; this\n> skill never auto-scans for individuals.\n\nThe second defining constraint is **measurement honesty**: self-reported confidence\nis not measured ability and every report labels which is which; a 5-item pre-quiz is\na coarse signal and findings carry instrument-strength caveats; small N and\nnon-response are stated, never papered over (`references/analytics_honesty.md`).\n\n## Quick Start\n\n```\nDesign a 10-minute ungraded diagnostic for week 1 of my data structures course\n开学前我想摸一下学生的底，帮我设计一份前测\nHere are the pre-quiz results — what does my class actually know coming in?\n根据课前问卷的结果，下周的课需要怎么调整？\nBuild peer-instruction groups from the diagnostic results\n期中了，重新分析一下学生的基础有没有变化\n```\n\n## Modes\n\n| Mode | Trigger intent | Output |\n|------|---------------|--------|\n| `instrument` | \"Design a pre-test / readiness check\", 前测 / 预习问卷 — an ungraded diagnostic or questionnaire | Student-facing instrument + per-item analysis plan (every item names the decision it informs) from `templates/diagnostic_template.md` |\n| `cohort-profile` | \"Here are the results — what does my class know?\", 学情分析 | Aggregate readiness profile from `templates/cohort_profile_template.md` + proposed passport `learner_profile` update, aggregates only, shown verbatim |\n| `lesson-calibration` | \"How should next week's class change given this?\" | Concrete reteach/activate/skip, misconception, pacing, and differentiation adjustments for a specific lesson or week — feeds `lesson-builder` |\n| `grouping` | \"Put them in groups\", 分组 / 分层 for an activity or project | Evidence-based grouping plan matched to the pedagogical goal; compositions by pseudonym |\n| `progress` | \"Has the class moved since week 1?\", mid-term re-analysis | Cohort-level trajectory comparison across instruments (same-concept items), updated profile |\n\n**Mode dispatch rule:** results offered without a known instrument route through a\nshort provenance intake first — what produced these numbers determines what they can\nsupport (`references/analytics_honesty.md` §1). Detect intent in any language.\n\n### Does NOT trigger\n\n| Scenario | Use instead |\n|----------|-------------|\n| Graded quizzes, exams, or anything entering the gradebook | `assessment-architect` |\n| An individual student's situation — \"which students need help?\", outreach, feedback | `student-mentor` (professor initiates with the evidence; never auto-scanned from cohort data) |\n| End-of-term student evaluation analysis | `teaching-reflector` |\n\n## Agent Team (4)\n\n| Agent | Role |\n|-------|------|\n| `diagnostic_designer_agent` | Designs ungraded diagnostics and pre-lesson questionnaires: prerequisite probes, two-tier misconception items, labeled self-efficacy items — analysis plan written before deployment |\n| `cohort_analyst_agent` | The analysis core: per-concept readiness distributions, misconception prevalence, heterogeneity assessment, mandatory caveat block, aggregates-only passport update |\n| `calibration_advisor_agent` | Profile → teaching decisions: reteach/activate/skip per prerequisite, misconception-targeted adjustments, pacing flags, within-classroom differentiation — every recommendation traceable to a finding |\n| `grouping_strategist_agent` | Grouping plans by pedagogical goal: heterogeneous, homogeneous, or role-based; pseudonymous output; rotation cadence; refuses learning-styles pseudoscience |\n\n## Workflow (`cohort-profile` mode)\n\n```\nPhase 0 INTAKE — collect: the data export, what instrument produced it (if this\n skill designed it, the analysis plan already exists), when it\n ran, N and enrollment. Ask only for the columns the analysis\n needs; suggest the professor strip names before sharing the\n file (iron rule 6). Unknown provenance = ask, don't guess.\nPhase 1 PSEUDONYMIZE — named/identifiable rows get session pseudonyms (S01, S02, …)\n before analysis; the mapping stays with the professor; the raw\n file never leaves the professor's hands.\nPhase 2 ANALYZE — cohort_analyst computes per-concept aggregates: readiness\n distributions (spread, not just means), misconception\n prevalence, heterogeneity shape — every finding carrying its\n instrument-strength and N caveats\n 🧑 checkpoint: profile report + proposed passport learner_profile update —\n aggregates only, shown verbatim before anything is written\nPhase 3 CALIBRATE — routed offers: pre-term findings → course-designer (outcomes /\n schedule recalibration); in-term findings → lesson-builder\n (next week's build via lesson-calibration mode); individual\n follow-up the professor wants to make → student-mentor,\n professor-initiated with the evidence\n```\n\n`instrument` mode runs diagnostic_designer alone, ending in a checkpoint on the\ninstrument plus its analysis plan. `lesson-calibration` and `grouping` require an\nexisting profile (or run `cohort-profile` first); `progress` re-runs Phases 0–2 on\nthe new instrument and adds the trajectory comparison.\n\n## Iron rules\n\n1. **Cohort-only passport writes.** Aggregates only — distributions, prevalence\n percentages, heterogeneity measures — into `learner_profile` (`cohort_evidence`\n sub-object + evidence-tagged `known_difficulties` entries), shown verbatim and\n confirmed at a checkpoint before writing. No names, no per-student rows, no\n individual-level fact, ever — in the passport or any other state file.\n2. **No prediction, no tracking labels.** Analysis describes current evidence; it\n never forecasts an individual student's future and never produces ability labels\n that become tracks (`references/analytics_honesty.md` §2 for the rationale).\n3. **Self-report is not measured ability.** Every report keeps the two in separate,\n labeled sections; a confidence item presented as a readiness finding is a defect.\n4. **Instrument-strength caveats are mandatory.** The caveat block in every profile\n report (mirroring teaching-reflector's §11 block) is not removable by\n configuration, instruction, or \"just proceed.\"\n5. **Individual questions route to student-mentor.** \"Which students…\" requests get a\n refusal with the pointer, not a quiet answer. The professor initiates that work\n with the evidence; this skill never nominates students.\n6. **Data minimization.** Ask only for the columns the analysis needs; suggest the\n professor strip names before sharing the file at all. The least data that answers\n the question is the right amount of data.\n\n## Outputs\n\n- `cohort/diagnostic_.md` — instrument + per-item analysis plan, from\n `templates/diagnostic_template.md`\n- `cohort/cohort_profile_.md` — from `templates/cohort_profile_template.md`\n- `cohort/lesson_calibration_.md` — adjustments keyed to the week's plan\n- `cohort/grouping_plan_.md` — pseudonymous compositions + rotation cadence\n- Passport update (confirmed only): `learner_profile.cohort_evidence[]` +\n evidence-tagged `known_difficulties[]` entries — aggregates only\n\n## References\n\n- `references/analytics_honesty.md` — instrument-strength table, no-prediction /\n no-tracking rationale, self-report limits, small-N rules, the privacy architecture\n operationalized, learning-styles refusal, aggregation rules\n- `references/diagnostic_design_guide.md` — probe patterns, two-tier item anatomy\n with worked examples, what not to ask, named-vs-anonymous tradeoff, deployment\n checklist\n- `templates/diagnostic_template.md`\n- `templates/cohort_profile_template.md`\n- Shared: `shared/pedagogy_foundations.md` (§5, §9, §11),\n `shared/course_passport_schema.md` (learner_profile; Iron Rule 2),\n `shared/checkpoint_protocol.md` (person-affecting hard rule)\n","tagline":"Learner and cohort analysis (学情分析) for university professors — cross-cutting support for design, builds, and the weekly loop. 4-agent team turning professor-held student data — ability lists, pre-course diagnostics, pre-lesson questionnaire results — into evidence-based teaching ","category":"data","commerce":{"type":"unknown","billing":"unknown","amount":null,"currency":null,"sourceUrl":null,"checkedAt":null,"runtime":"unknown","purchaseUrl":null,"checkout":"external","purchaseRequiresUserConsent":true},"tags":["agent-skill"],"author":"YujxZJCN","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github candidate review","sourceDetail":"YujxZJCN/teaching-skills","creatorName":"YujxZJCN","creatorUrl":"https://github.com/YujxZJCN","sourceUrl":"https://github.com/YujxZJCN/teaching-skills/tree/main/cohort-analyst","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/yujxzjcn-cohort-analyst#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
