  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by anthropics on GitHub. Read the source before you install it.

Installation

Install the Case Brief AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/anthropics/claude-for-legal/tree/main/law-student/skills/case-brief
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/anthropics/claude-for-legal.git /tmp/claude-for-legal
mkdir -p .claude/skills
cp -r /tmp/claude-for-legal/law-student/skills/case-brief .claude/skills/case-brief
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Case Brief in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Case Brief on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Case Brief is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

/case-brief

  1. Load ~/.claude/plugins/config/claude-for-legal/law-student/CLAUDE.md → outline/brief preferences.
  2. Apply the workflow below.
  3. Brief in the student's format. If drill-me mode: ask the student to state the holding first.

Purpose

A case brief is a tool for remembering what a case does. This skill makes one in your format — the format you'll actually use in your outline.

Confidence discipline

Case briefs state holdings, rules, and reasoning. Getting them wrong turns your outline into a false map. The rule for this skill:

  • If you paste the case text: I extract holding/rule/reasoning from what's in front of me. Confident.
  • If you only give a case name: I brief from knowledge. Worth a lot less. I flag every line I'm not sure about with [UNCERTAIN: specific reason], and I strongly recommend you confirm against the actual case before putting the brief in your outline. If I don't know the case well enough, I say so.
  • If the case has famous-but-contested interpretations: I give the majority read and [VERIFY: check your casebook and professor's framing].

A brief built on my guess and your good faith is worse than no brief. Better to err toward "I'm not sure — read it yourself" than to invent.

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

A brief you didn't write is a brief you won't remember. Every mode of this skill defaults to scaffolding the student's brief-writing, not to writing the brief.

What this skill will do in every mode:

  • Ask the student what they already got from reading: the facts, the issue, the holding as they understand it.
  • Provide the blank template in their preferred format (headings for Facts, Issue, Holding, Reasoning, Rule, Notes).
  • Ask pointed follow-ups on whichever section is thin: "What were the key facts the court actually relied on?", "What's the narrow issue vs. the broader question?", "Why did the court reject the dissent's framing?"
  • If the student pastes the case text, extract verbatim the court's own language for holding and reasoning — that is not writing-for-them; that is pointing at what the case says.
  • Flag confused or wrong understandings: "You said the holding is X. The court's actual language is closer to Y. Which one is the rule you'll carry into your outline?"

What this skill will not do, even if asked:

  • Write a full case brief from a case name alone. That is the exact thing the student is learning not to need.
  • "Summarize this case for me" — refused. The brief is for remembering, which requires writing.

Exception (the only one): the student explicitly overrides — "I've read it three times, I'm stuck on phrasing the holding, just give me a starter sentence so I can rewrite it." Then write a minimal starter with [VERIFY] flags and prompt them to rewrite in their own words before it goes into an outline.

Mode fork

Drill-me mode: Ask the student to state the holding before anything else:

"You've read this case. What's the holding? One sentence."

If they can't state it, make them read it again. The brief is a memory aid, not a substitute for reading. Then proceed to the scaffold — ask them to state facts, issue, reasoning, and rule in turn. Push back on thin or wrong statements.

Explain-to-me mode: Same scaffolded workflow, softer tone. The skill walks the student through each section, offers structural prompts ("a good holding is one sentence, yes/no + the rule"), but still waits for the student to write the content. Explain-to-me does not mean "write the brief for me." It means "explain what a good brief looks like, and guide me through writing mine."

If the student pastes the case text in either mode, the skill can extract the court's own language into the Facts/Holding/Reasoning slots — that's not writing-for-them, that's pointing at the source.

The brief — scaffold, then the student fills

The skill produces the template with questions, not the filled-in brief. Student fills each section; skill reviews, pushes back, suggests what's missing.

Per the student's format in ~/.claude/plugins/config/claude-for-legal/law-student/CLAUDE.md. If none captured, default:

markdown
## [Case Name], [cite]

**Court:** [court, year]

**Facts:** [The facts that matter to the holding. Not every fact — the ones
the court relied on. Two to four sentences.]

**Procedural posture:** [How did this get here? Trial court ruled X, this
is an appeal from that. One sentence.]

**Issue:** [The question the court answered. Phrased as a yes/no question.]

**Holding:** [The answer. One sentence. Yes/no + the rule.]

**Reasoning:** [Why. The court's logic. This is where the law is. Three to
five sentences.]

**Rule:** [The rule you'd put in your outline. The portable takeaway.]

**Notes:** [Dissent worth knowing? Distinguishable on these facts? How
professor emphasized it?]

---

**Citation check.** The case cite, quoted language, and any supporting authority above were generated by an AI model and have not been verified. Before you rely on them — in a brief, memo, outline entry, or exam answer — look them up on Westlaw, CourtListener, or your school's research tool. AI-generated citations are sometimes fabricated or misquoted.

Depth calibration

Per ~/.claude/plugins/config/claude-for-legal/law-student/CLAUDE.md — some students want one-line briefs (rule + cite), some want full treatment. Match their format.

If they're a 1L still learning to read cases: fuller briefs. If they're a 3L doing bar prep: rules only.

What this skill does not do

  • Brief a case the student hasn't read. In drill-me mode, the holding check enforces this.
  • Tell you what's on the exam. Brief everything; the exam will surprise you.
  • Brief from memory without flagging. If you only give me a case name and I brief from what I think I know, every line I'm unsure about gets [UNCERTAIN] or [VERIFY]. Don't put a brief in your outline unless you've confirmed it against the actual case.

Frequently asked questions

What does the Case Brief AI skill do?

Brief a case in your preferred format. In drill-me mode, makes the student state the holding first. Use when the user says "brief [case]", "what's the holding in", "case brief", or pastes a case.

Why use Case Brief on TypingMind?

Because you install it once and use it with any model. Case Brief is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Case Brief in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/anthropics/claude-for-legal/tree/main/law-student/skills/case-brief. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Case Brief?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Case Brief?

As many as you like. As long as a model supports skills, you can use Case Brief with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Case Brief AI skill free?

Yes. It is published on GitHub by anthropics under the Apache-2.0 license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
