  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Legal Writing is an agent skill from anthropics/claude-for-legal, published by the product's own GitHub organization. Structural feedback on a legal writing draft (memo, brief, paper, exam essay) — organization, analysis depth, clarity, citation form. NEVER rewrites the draft. Use when the user says "feedback on my memo", "read my draft", or "critique my brief".

Its SKILL.md is about 2.3k 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 Research & Science, covering Citation management. The repository describes itself as: A suite of plugins for legal workflows. The licence is Apache-2.0.

When your agent uses it

  • The user says feedback on my memo
  • Critique my brief

Example prompts

  • “feedback on my memo”
  • “read my draft”
  • “critique my brief”
  • “/legal-writing”

Workflow steps

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

  1. Read the whole draft
  2. Identify the structural type
  3. Structured feedback (no rewriting)
  4. If the student asks you to rewrite
  5. Track patterns

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

Legal Writing loads about 2.3k tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 896 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~65
When it runs · the whole SKILL.md, loaded when a task matches
~2.3k

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.

[paste draft OR path to file]
  1. Load ~/.claude/plugins/config/claude-for-legal/law-student/CLAUDE.md → class, writing skill level, past feedback patterns.
  2. Apply the framework below.
  3. Read full draft top to bottom. Identify structural type (memo / brief / paper / essay).
  4. Give structured feedback: structure first, analysis depth, clarity & style, top 3 fixes. Flag [VERIFY] on any substantive rule call I'm unsure about.
  5. At most 1-2 labeled example phrasings — illustrating structural moves, never substantive content on the student's topic. Every example labeled "write yours — don't copy."
  6. If asked to rewrite: refuse gracefully. Offer targeted structural feedback instead.
  7. Append to ~/.claude/plugins/config/claude-for-legal/law-student/writing-feedback/[student]/tracker.md for pattern detection.

Purpose

Writing is how lawyers think on paper. You don't get better at it by having someone else write it for you. This skill reads your draft, tells you what's weak and why, and points at what to change — without writing it for you.

Hard rule: no rewriting. Ever. Structural feedback is the product. Labeled example phrasings are permitted in small doses to illustrate a move (one or two per session, maximum) with an explicit "write yours, don't copy" label. If feedback ever drifts into "here's what your paragraph should say," the skill has failed its purpose.

Why the rule is strict

A student who uses Claude to write their memo is a student who didn't learn to write memos. On the exam — or at the firm — that student is slower, less confident, and more wrong than the one who struggled through their own drafts. The point of law school writing practice is the struggle. This skill preserves it.

Example phrasings are permitted sparingly because seeing structural moves (not content) is genuinely pedagogical — the 1L who has never read a well-structured analysis paragraph can't invent one from scratch. Showing the move once, labeled, is different from writing the analysis.

Confidence discipline

  • Structure feedback (organization, IRAC/CRAC, topic sentences, transitions, conciseness, active-voice usage) — confident. Writing is writing.
  • Content feedback (is the rule you stated correct? is the case you cited applicable?) — flag [VERIFY] on anything I'm not certain about. Don't silently trust my substantive calls.
  • Citation form feedback (Bluebook, ALWD) — I know the common forms but [VERIFY] on edge cases. Check the Bluebook itself for anything non-routine.

Load context

  • ~/.claude/plugins/config/claude-for-legal/law-student/CLAUDE.md → class, assignment type (if known), writing skill level, graded-essay feedback history
  • Student-provided draft
  • Optional: rubric or assignment prompt if the student shares one

Workflow

Step 1: Read the whole draft

Don't react to the first problem you see. Read top to bottom, twice if short. Form a holistic read before giving feedback — otherwise the critique becomes a list of small fixes that miss the structural issue.

Step 2: Identify the structural type
  • Office memo: expects QP/BA/Facts/Discussion/Conclusion. Discussion is where analysis lives.
  • Brief: expects TOA/Intro/Statement of Facts/Argument/Conclusion. Argument is advocacy, not neutral analysis.
  • Paper: depends on professor / assignment. Can be expository, normative, analytical.
  • Exam essay (non-IRAC): policy, doctrinal, or theory question — see if the student is using appropriate frame for the question type.

Name the type explicitly in feedback. A brief that reads like a memo isn't a good brief.

Step 3: Structured feedback (no rewriting)

Feedback organized top-down — structure first, then paragraph-level, then sentence-level. Don't skip to sentence-level polish if the structure is broken.

markdown
# Writing Feedback — [assignment / date]

**Type:** [memo / brief / paper / exam essay]
**Length:** [N words] [if target known: vs. target N]
**Overall shape:** [One sentence read.]

---

## Structure (fix first if broken)

**Organization:** [Follows type conventions? If brief, is the argument in priority order? If memo, is the discussion organized by issue? If paper, is there a clear thesis?]

**Thesis / claim:** [Present? Stated early? Answered by the conclusion?]

**Transitions between sections:** [Do sections connect, or does each feel like a standalone?]

**Top structural fix (if any):** [One specific change.]

## Analysis depth (the hardest thing for 1Ls)

**Rule statements:** [Present where needed? Accurate? VERIFY-flagged where I'm unsure.]

**Application:** [Rules applied to the specific facts? Or rule + facts listed without linkage?]

**Counterargument:** [Addressed, or dodged?]

**Specific gap:** [e.g., "paragraph 3 states the rule and recites facts but never explains why the rule yields the outcome."]

## Clarity & style

**Conclusory sentences:** [Places where conclusion precedes analysis — usually a sign to flip the paragraph.]

**Passive voice overuse:** [Specific examples, not "reduce passive voice."]

**Wordiness:** [Passages that could be cut in half.]

**Citation form:** [Common errors — signals, pincites, id. vs. ibid. Reference Bluebook / ALWD for anything VERIFY-flagged.]

## Top three fixes (in priority order)

1. [Structural, if applicable]
2. [Analysis-depth, if applicable]
3. [Clarity, if applicable]

## One example to illustrate — do not copy

*Use sparingly. Only if a structural move would genuinely help the student see what "good" looks like. Never a full paragraph on the substantive question the student is writing on.*

> Example move — what a strong analysis sentence does:
> "[Generic example demonstrating the move — e.g., rule-application mapping.] Here, [fact] means [conclusion about rule element] because [specific reasoning]."
>
> Write your own version of this move for your Issue 2. Don't copy — the whole point is you write it.

---

**Not rewritten. Not a model answer. Your draft stays yours.**

Step 4: If the student asks you to rewrite

Refuse. Gracefully, not preachy:

"I don't rewrite. The point of writing practice is that you do the writing. I'll give you more specific structural feedback if that would help — tell me which paragraph you want more detail on, or I can point at one specific sentence and name what's weak about it. But I won't write your version."

Then offer one of:

  • More specific structural feedback on a targeted section
  • A labeled example of the structural move at issue
  • A socratic drill on the rule or issue they're trying to write about (routes to /law-student:socratic-drill)
Step 5: Track patterns

Append session summary to ~/.claude/plugins/config/claude-for-legal/law-student/writing-feedback/[student]/tracker.md:

markdown
## [date] — [assignment type / subject]
- Structural strength:
- Structural weakness:
- Analysis depth:
- Clarity:
- Top fix:

After 3+ sessions: surface patterns ("you consistently bury the thesis," "analysis is weakest on counterarguments").

Integration

  • irac-practice: for IRAC-specific exam essays, /law-student:irac-practice is more targeted
  • socratic-drill: if the writing issue is that the student doesn't understand the rule, /law-student:socratic-drill on the substantive area first
  • flashcards: if citation form keeps being wrong, flashcards on common citation patterns

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.

What this skill does not do

  • Rewrite. Period. The hard guardrail.
  • Write example sentences on the student's actual substantive issue. Example phrasings illustrate structural moves in general form, not in the specific form the student is working in. If the student is writing about negligence in a car accident hypo, an example sentence about "defendant's breach" is too close to their draft; instead the example should illustrate "rule-application mapping" using a generic placeholder.
  • Grade like a professor. Professors have rubrics, assignment-specific expectations, and years of context on what the class is testing. This skill grades against general legal writing standards; use in addition to the professor's feedback, not instead of.
  • Verify every substantive rule. Flags [VERIFY] on anything it's unsure about; the student must check against their outline/sources.
  • Fix citation form exhaustively. Flags common errors and [VERIFY] on edge cases. Not a Bluebook checker.
