## What it does

The skill loads `~/.claude/plugins/config/claude-for-legal/law-student/CLAUDE.md` for the class, professor, exam format and syllabus. You hand it past exams as PDFs, pasted text or file paths. Each paper gets read on its own: question count, subject coverage and proportions, question style, fact-pattern density, recurring traps.

Then comes the cross-exam pass. What stays stable across papers, what varies, which syllabus topics never showed up in past exams. Output lands in `~/.claude/plugins/config/claude-for-legal/law-student/exam-forecasts/[class]/forecast-[YYYY-MM-DD].md` with subject weights, expected format and a study emphasis recommendation. The author frames it as a weighting heuristic, not a prediction.

With fewer than three past exams the skill flags a thin sample and says the inference is weak. One or two papers are noise, so treat that report as a reason to hunt for more material. A new professor with no past exams means no forecast at all — you get the syllabus topic list and nothing more.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add anthropics/claude-for-legal --skill exam-forecast -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/exam-forecast/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/exam-forecast/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add anthropics/claude-for-legal --skill exam-forecast -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/exam-forecast/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add anthropics/claude-for-legal --skill exam-forecast -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/exam-forecast/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install anthropics/claude-for-legal exam-forecast
```

2. **Manually: put the files in place**
- File: `.github/skills/exam-forecast/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add anthropics/claude-for-legal --skill exam-forecast -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/anthropics/claude-for-legal --path law-student/skills/exam-forecast
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/exam-forecast/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add anthropics/claude-for-legal --skill exam-forecast -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/anthropics/claude-for-legal/tree/HEAD/law-student/skills/exam-forecast/SKILL.md

## When to use it
- break down past papers and see subject weights
- spot traps the professor repeats every year
- separate stable patterns from one-off appearances
- decide where to spend study time
- check syllabus topics against what was actually tested

## Example prompts
- /exam-forecast contracts, past exams attached
- analyze these four papers and tell me what repeats
- what has this professor tested before

# /exam-forecast

1. Load `~/.claude/plugins/config/claude-for-legal/law-student/CLAUDE.md` → class, professor, exam format, syllabus.
2. Apply the workflow below.
3. Intake past exams (PDF, paste, or paths). Confirm sample size.
4. Analyze each past exam: format, subject coverage, question style, fact-pattern density, recurring traps.
5. Cross-exam pattern analysis — what's stable, what varies.
6. Combine with current syllabus to produce forecast: subject weights, format, hobby horses, study emphasis.
7. Write `~/.claude/plugins/config/claude-for-legal/law-student/exam-forecasts/[class]/forecast-[YYYY-MM-DD].md`. Framed as weighting heuristic, not prediction.

## Purpose

Every professor's exam has fingerprints. The same hypo structures recur. The same traps come back. The same subject ratios repeat. Students who have prior exams study smarter; students who don't, study harder. This skill analyzes the prior exams you have and surfaces the patterns.

Not magic. A forecast, not a prediction. The skill cannot tell you what's on the exam — it can tell you what's been on past exams and what's likely to recur based on syllabus coverage.

## Confidence discipline

- Pattern analysis (what subjects appeared, how many questions per topic, how often policy vs. rule-application) — confident where the exams are clearly in front of me.
- Inference about likely emphasis on upcoming exam — `[UNCERTAIN]` is the default; these are forecasts, not certainties. Explicitly frame as "based on the [N] past exams you shared, [topic] appeared in [M]. Your upcoming exam may emphasize it, or the professor may rotate — use this as a weighting for review time, not a prediction."
- If only 1-2 past exams are available, say so explicitly — any pattern inferred from 1 exam is noise.
- If the professor is new (no past exams available), skill can't forecast. Say so; fall back to syllabus-based "these are the subjects covered" only.

## Load context

- `~/.claude/plugins/config/claude-for-legal/law-student/CLAUDE.md` → current classes, exam formats, syllabus if captured
- User-provided past exams (PDF, pasted text, paths)
- Optional: syllabus for the current class (for "what's been covered to date")
```
