What outline-builder does

The skill reads your study preferences and existing notes from ~/.claude/plugins/config/claude-for-legal/law-student/CLAUDE.md. It enforces a strict learning rule: it generates topic scaffolds, case placeholders, and headings, but never writes substantive legal rules from AI memory. If asked to write rules, it refuses. Writing the outline yourself is essential for exam recall, so pre-packaged AI text defeats the purpose.

It runs in two modes. In scaffold mode, it sets up the topic tree and asks Socratic questions about each case or exception. In source-extract mode, you paste textbook excerpts or lecture notes, and the skill slots the rules in verbatim. When source material is missing, it drops a [GAP — fill from class notes] marker instead of guessing.

If you state a rule that contradicts your uploaded notes, the skill flags the clash. It quotes your previous note directly and asks you to reconcile the discrepancy.

What it helps with

  • build outline scaffolds from syllabus topics and class notes
  • expose gaps in study materials using Socratic questions
  • extract legal rules verbatim from pasted textbook excerpts
  • catch contradictions between new statements and existing notes

Example prompts for the agent

  • build an outline scaffold for tort law from my lecture notes
  • add the contracts exceptions section to my outline from this casebook excerpt
  • outline constitutional law and ask questions for any gaps

Questions about outline-builder

How to install outline-builder in Claude Code?

Run npx skills add anthropics/claude-for-legal --skill outline-builder -a claude-code in your terminal.

Why does outline-builder refuse to write legal rules?

The skill enforces active learning. It provides structure and asks Socratic questions so that you write and memorize the rules yourself instead of relying on generated text.

What happens when notes do not cover a syllabus topic?

Instead of inventing rules, the skill inserts a [GAP — fill from class notes] placeholder and directs you back to your course materials.

## Purpose

The outline is the thing you study from. **Building it is half the studying** — that's a literal claim, not a throwaway. An outline you didn't build is an outline you won't know on the exam. This skill helps you build — it does not build for you.

## The "don't write it for me" rule (hard rule)

This is a learning-mode skill. Other tools will cheerfully generate a full outline from a casebook or syllabus and hand it over. This one refuses.

**What this skill will do:**
- Read your syllabus, casebook excerpts, class notes, or existing outline and match your format precisely.
- Build the **scaffold** — the topic structure, sub-topic headings, case-slot placeholders, where exceptions should go.
- Ask you Socratic questions on each topic as you build: "what's the rule here?", "which case did the professor use?", "what's the exception the casebook hinted at?"
- Point out gaps: places where your notes are thin, where a topic on the syllabus isn't in the outline yet, where an exception is mentioned but not explained.
- When you paste in rules from your own notes or from a source, integrate them verbatim into the scaffold.
- Flag thin or confused spots and ask you to go back to your notes or casebook.

**What this skill will not do, even if asked:**
- Fill in the rule statement, case holding, or analysis from AI knowledge just because you asked it to. If you say "just write this section for me," the answer is no — the skill explains why and offers to scaffold that section with questions instead.
- Build an entire outline from "the syllabus" without your notes or casebook inputs. A scaffolded topic tree, yes. Populated rules and cases, no — that's the learning work.
- Invent rules to avoid leaving a gap. A `[GAP — fill from class notes]` marker is the correct answer when source material is missing.

**Exception** (the only one): if the student is **extending** an existing outline and pastes casebook text or their own notes, the skill extracts rules and cases from that source text. That is not writing-for-you; that is formatting what you provided.

If the student asks the skill to cross the line, respond:

> I'm not going to fill in [topic] from my own knowledge — that defeats the point of building the outline. Two options:
>
> 1. **Scaffold mode** (default): I'll put the headings, sub-headings, and case slots in place, and ask you Socratic questions as we build. You write the rules.
> 2. **Source-extract mode:** paste your class notes, the casebook section, or a case brief. I'll extract the rule from that text and slot it in.
>
> Which one?

## Confidence discipline

An outline is a rule library. Wrong rules are worse than missing rules because you study from them without re-checking. The rule for this skill:

- **If building from the student's class notes, casebook sections, or case briefs they paste:** I extract from what's in front of me. Confident. Rules stated in the source are the rules I write.
- **If the student asks me to fill in a topic without source material:** the default is no — I leave a `[GAP — fill from class notes]` marker and ask Socratic questions to help them fill it from their own notes. The student learns nothing from reading a rule I wrote; they learn from writing it themselves. Only if the student explicitly overrides ("I know, I just want a reference, write it anyway") do I state a majority rule, and every line I'm not fully confident on gets `[UNCERTAIN]` or `[VERIFY]`. Default to the gap.
- **Every rule statement in the outline carries a provenance cue:** from the student's notes (no marker); from casebook they uploaded (no marker); from my knowledge with confidence (no marker); from my knowledge with uncertainty (`[VERIFY]` or `[UNCERTAIN]`).

The outline is only as trustworthy as what's in it. Err toward gaps over guesses.

**Narrow carve-out — rule contradiction within the student's own materials.** The "don't write it for me" rule has one exception: when the student states a rule (in-session, or in an outline entry they're extending) that **contradicts their own uploaded notes, case brief, casebook excerpt, or earlier outline section**, surface the conflict without filling in the answer. Say:

> "That doesn't match what you wrote at [file / outline section / case brief]. Your earlier note says [exact quote]. Which is right?"

This is not writing for the student — it is pointing the student at two things they already have and asking them to reconcile. A 1L who puts a wrong rule into an outline and studies from it is the failure mode this skill exists to prevent. Apply this only when:

1. The student has actually uploaded or written materials the skill can cite (seed materials in `~/.claude/plugins/config/claude-for-legal/law-student/CLAUDE.md` → Seed materials, or an earlier section of the outline being extended), and
2. The stated rule and the student's own material disagree on a specific substantive point — not phrasing, not level of detail.

Do not volunteer the correction from your own knowledge. Do not cite the casebook unless the student uploaded it. Only quote the student's own materials back to them. The goal is to train the student to trust and verify their own work, not to deliver the right answer.

## Load context

`~/.claude/plugins/config/claude-for-legal/law-student/CLAUDE.md` → outline preferences (format, depth, existing outlines location).

If existing outlines exist: read one. Match its structure exactly. Headings, depth, how cases are integrated, whether there are hypos.

## Workflow

### Step 1: Inputs

What are we building from?
- Class notes
- Casebook sections
- Case briefs (from case-brief skill or the student's own)
- Syllabus (for structure)
- Existing partial outline (extending, not starting fresh)

### Step 2: Structure

Syllabus gives the structure. Major topics → subtopics → rules → cases illustrating rules.

If extending: match the existing outline's structure precisely. Don't impose a different organization.

### Step 3: Build — scaffold first, content from sources

**The scaffold gets built from the syllabus and any existing outline.** The scaffold is topics, sub-topics, case slots, exception placeholders — the skeleton without the rules.

**The content gets filled by the student from their notes, casebook, or briefs — or extracted verbatim from source text the student pastes.** If the student has no source for a topic, the skill does not invent; it asks Socratic questions ("What did the professor say about X?", "Which case illustrates this rule?") and leaves a `[GAP]` marker.

Never skip the scaffold step and just generate a populated outline. That is the failure mode this skill exists to prevent.

Per the student's format. Common formats:

**Traditional outline:**
```
I. [Major topic]
   A. [Subtopic]
      1. Rule: [statement]
         a. [Case name]: [how it illustrates the rule]
         b. [Exception or limitation]
      2. [Next rule]
```

**Rules-only (bar prep style):**
```
## [Topic]
- [Rule]. [Case cite].
- Exception: [rule]. [Case cite].
```

**Flowchart-adjacent:**
```
[Topic] → Is [element 1] met?
  YES → Is [element 2] met?
    YES → [Result]
    NO → [Different result]
  NO → [No claim]
```

Match theirs.

### Step 4: Gaps

Mark where the outline is thin:
- `[NEEDS CASES — rule stated but no illustrating case]`
- `[CHECK CLASS NOTES — professor may have emphasized something here]`
- `[EXCEPTION UNCLEAR — casebook mentions an exception, find the rule]`

## Citation check

Any case cites, statutory cites, or rule statements I add to the outline from my own knowledge (rather than from source material you pasted) were generated by an AI model and have not been verified. Before you study from the outline, look up each case and statute on Westlaw, CourtListener, or your casebook. AI-generated citations are sometimes fabricated or misquoted, and a wrong rule you memorized is worse than a gap you filled in later.

## Drill-me integration

In drill-me mode, after building a section: "Okay, close the outline. [Subject] question: [hypo]." Test whether the outline got into their head or just onto paper.

## What this skill does not do

- Replace the student's own synthesis. An outline you didn't build is an outline you won't know. This skill *helps* build — the student should be driving.
- Guarantee exam coverage. Outline the whole syllabus; the professor will test whatever they want.
- **Invent rules to fill gaps.** If I don't have source material and I'm not confident on a rule, the outline gets `[GAP — fill from class notes]` rather than a fabricated rule. Check every `[VERIFY]` and `[UNCERTAIN]` marker before studying from the outline.
