exam-forecast

exam-forecast is a skill for Claude Code from anthropics/claude-for-legal. It costs 73 tokens per session (2,120 once invoked), scanned A, original, Apache-2.0.

An analysis of a professor's past exams and the current syllabus to identify recurring topics, question styles, and common traps. Its result is a study forecast, not a claim about what the next exam will contain.

In plain words
What is it for?
Use it to compare past exams, see how much attention subjects receive, identify repeated hypothetical patterns, and choose study priorities.
Why use it?
It replaces vague guessing with evidence from earlier exams while making clear that past patterns cannot predict an exam with certainty.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

exam-forecast scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 166 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/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")

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
