What it does

Memo is an agent skill from anthropics/claude-for-legal, published by the product's own GitHub organization. IRAC-scaffolded case analysis memo with research gaps flagged — the scaffold, not the analysis. Rule blocks are RESEARCH NEEDED, Application is STUDENT ANALYSIS prompts, Conclusion is blank. Use when a student needs to scaffold a case analysis memo, write up their analysis, or build an IRAC memo for a case.

Its SKILL.md is about 2.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Project scaffolding. The repository describes itself as: A suite of plugins for legal workflows. The licence is Apache-2.0.

When your agent uses it

  • A student needs to scaffold a case analysis memo
  • Write up their analysis
  • Build an IRAC memo for a case

Example prompts

  • “/memo”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Frame the issues
  2. Scaffold the IRAC
  3. Identify strengths, weaknesses, open questions

What it can do on your machine

Read from SKILL.md and the folder at commit 4a6c651. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Memo loads about 2.5k tokens when it runs. Until then it costs about 78 tokens; SKILL.md has 855 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~78
When it runs · the whole SKILL.md, loaded when a task matches
~2.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Memo: Internal Case Analysis

Purpose

The case analysis memo is where the student's thinking lives. This skill provides the IRAC scaffolding and flags the research gaps — the student fills in the analysis.

The analysis is the student's. This skill structures; it doesn't conclude.

Load context

~/.claude/plugins/config/claude-for-legal/legal-clinic/CLAUDE.md → practice areas, jurisdiction, supervision style. Intake summary and case notes for facts.

Pedagogy check

Read the supervisor guide for this practice area at ~/.claude/plugins/config/claude-for-legal/legal-clinic/guides/<practice-area>.md. Check the pedagogy_posture setting:

  • guide (default): Produce the IRAC structure and the research-gap list. Ask the student to draft each rule statement themselves from research, rather than giving them a framework. Give feedback on what they wrote. Offer to fill the framework rule for a section only when the student has tried once.
  • assist: Produce the memo scaffold and fill what can be filled. Flag items for student review. The student edits and learns by reviewing. (Note: this memo skill always leaves the [STUDENT ANALYSIS] and [STUDENT CONCLUSION] blocks blank by design — assist means the skill produces the IRAC scaffold and framework rule statement; it does not produce the application or the conclusion.)
  • teach: Don't produce the framework or the scaffold content. Ask the student to frame the issues, state the rules from their research, and do the application. Give feedback. Ask leading questions when they're stuck. Only show a model rule statement or a model application paragraph after two attempts, and only for the section they're stuck on. Track what they got right and wrong so the supervisor can see progress.

If no guide exists, use guide. If the guide exists but doesn't set a posture, use guide.

Whatever the posture, the output always includes: "Pedagogy mode: [assist/guide/teach] — set by your supervisor's guide. This means I [description of what the student did vs what the skill did]."

Workflow

Step 1: Frame the issues

From the intake summary and case notes: what are the legal questions this case presents?

State each as a question. Not "habitability" — "Can the client assert a habitability defense to the eviction based on the broken heater, and if so, does it offset the rent owed?"

If there are multiple issues, each gets its own IRAC block.

Show full SKILL.md (440 more words)Show less
Step 2: Scaffold the IRAC

For each issue:

Issue: Stated as a question (from Step 1).

Rule: This is a research gap, not a conclusion. State what the student needs to find:

[RESEARCH NEEDED: [State] habitability doctrine — warranty of habitability elements, what conditions qualify, remedies available including rent offset. Start with: [State] landlord-tenant statute, then case law on heater/heat specifically. See /research-start for a roadmap.]

If the skill has high confidence in the general rule framework (e.g., "most states recognize an implied warranty of habitability"), state that as a framework starting point — but explicitly mark it as unverified:

Framework (unverified — confirm for [State]): Most jurisdictions recognize an implied warranty of habitability requiring landlords to maintain conditions fit for human occupation. Breach may give rise to rent withholding, repair-and-deduct, or rent abatement. [VERIFY: [State]'s specific elements and remedies]

Application: This is where the student's analysis goes. Scaffold the structure, don't fill it:

`[STUDENT ANALYSIS: Apply the rule to the facts. Key facts to address:

  • Heater broken since November — how long is "unreasonable"?
  • Client notified landlord [when? how? documented?]
  • Landlord's response or lack thereof
  • [State]-specific: does client need to have given written notice? deposited rent in escrow? other procedural prerequisites?]`

List the facts that matter. Let the student do the applying.

Conclusion: Explicitly blank:

[STUDENT CONCLUSION: Based on your research and analysis above, what's the likely outcome? How strong is this defense? What are the weaknesses?]

Step 3: Identify strengths, weaknesses, open questions

Separate section, after the IRAC blocks:

Strengths (apparent from facts — student should test these):

  • [Fact that seems helpful and why]

Weaknesses (apparent from facts — student should assess how serious):

  • [Fact that seems harmful and why]
  • [UNCERTAIN: whether [X] is actually a weakness — depends on [State] rule on [Y]]

Open questions (things the memo can't answer without more info):

  • Factual: [what we don't know from the client]
  • Legal: [what needs research]
  • Strategic: [judgment calls for the student/professor]

═══════════════════════════════════════════════════════════════════════

## What this memo is NOT

This is a scaffold, not an analysis. The [STUDENT ANALYSIS] blocks are where
the educational value lives — filling them in is the work. A memo where those
blocks are still empty is a memo that hasn't been written yet.

---

**Cite verification — required before use.** Any framework rules, cases, or statutes suggested above were generated by an AI model and have not been verified. Before relying on any citation — or including it in client work — run it through Westlaw, CourtListener, or your clinic's research platform for accuracy and current good-law status. Flag unverified citations to your supervisor.

**Source attribution.** Tag every suggested citation in the scaffold with where it came from: `[Westlaw]`, `[CourtListener]`, or the MCP tool name for citations retrieved from a legal research connector; `[web search — verify]` for web-search citations; `[model knowledge — verify]` for citations recalled from training data; `[user provided]` for citations the supervising attorney or case file supplied. Citations tagged `verify` carry higher fabrication risk than tool-retrieved citations and should be checked first. Never strip or collapse the tags — they are the supervisor's fastest signal about which citations to verify.

**No silent supplement.** If a query to a configured research tool returns few or no results for a rule the memo needs, say so and stop. Do NOT fill the gap from web search or model knowledge without asking. Say: "The search returned [N] results from [tool]. Coverage appears thin for [rule / issue]. Options: (1) broaden the search query, (2) try a different research tool, (3) search the web — results will be tagged `[web search — verify]` and should be checked against a primary source before relying, or (4) leave `[RULE TO VERIFY]` and stop. Which would you like?" The supervising attorney decides whether to accept lower-confidence sources.

What this skill does NOT do

  • Write the analysis. It scaffolds the IRAC and flags the gaps. The student reasons through the application.
  • Provide verified rules. Every rule statement is explicitly unverified until the student researches it.
  • Reach conclusions. The C in IRAC is blank on purpose.
  • Replace the conversation with the professor. The Open Questions / Strategic section is the agenda for that conversation, not a substitute.

Close with the next-steps decision tree

End with the next-steps decision tree per CLAUDE.md ## Outputs. Customize the options to what this skill just produced — the five default branches (draft the X, escalate, get more facts, watch and wait, something else) are a starting point, not a lock-in. The tree is the output; the lawyer picks.
