Study Plan
anthropics/claude-for-legal
Build or update a long-term bar prep (or exam prep) study plan — phases, subjects weighted by weakness, daily session schedule, adaptive to session history in study-plan.yaml.
Study 3-5 samples of the user's real writing and decisions, build an explicit 'how you think' profile, then draft new work as their understudy — always with a 'what I couldn't infer about you' list…

What it does
The Understudy is an agent skill from mohitagw15856/pm-claude-skills. Study 3-5 samples of the user's real writing and decisions, build an explicit 'how you think' profile, then draft new work as their understudy — always with a 'what I couldn't infer about you' list so the gaps are visible instead of guessed. Use when someone says 'write it like I would', 'learn my style', 'draft this as me', or wants an AI that apprentices to their judgment rather than imitating their tone. Produces a thinking profile, an understudy draft, and the couldn't-infer list.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.
When your agent uses it
- Someone says write it like I would
- Draft this as me
- Wants an AI that apprentices to their judgment rather than imitating their tone
Example prompts
- “s real writing and decisions, build an explicit”
- “profile, then draft new work as their understudy — always with a”
- “t infer about you”
- “/the-understudy”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Study decisions, not diction. For each sample extract: what it leads
- Write the profile in falsifiable lines. "Leads with the decision, then
- Draft under the profile. Apply the decision patterns first, the voice
- Deliver the couldn't-infer list. Each entry: the gap, the guess made,
- Offer the profile as a file (understudy-profile.md) so the study cost
What it can do on your machine
Read from SKILL.md and the folder at commit 1cbf1f0. 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.
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
The Understudy loads about 1.3k tokens when it runs. Until then it costs about 126 tokens; SKILL.md has 627 words of instructions outside code blocks.
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.

- Study 3-5 samples of the user's real writing and decisions, build an explicit 'how you think' profile, then draft new work as their understudy — always with a 'what I couldn't infer about you' list so the gaps are visible instead of guessed. Use when someone says 'write it like I would', 'learn my style', 'draft this as me', or wants an AI that apprentices to their judgment rather than imitating their tone. Produces a thinking profile, an understudy draft, and the couldn't-infer list.
The Understudy Skill
"Write it in my style" usually gets tone cosplay: the em-dashes copied, the judgment absent. An understudy studies differently — not how the principal sounds but how they decide: what they lead with, what they refuse to say, where they hedge and where they commit, what they always ask before answering. This skill runs a real apprenticeship: extract the thinking from samples, show the profile for correction, draft under it, and keep an honest list of everything it had to guess — because the fastest way to learn someone's judgment is to show them exactly where you don't have it yet.
What This Skill Produces
- A thinking profile built from samples: decision patterns, argument structure, commitments and hedges, taboos, signature moves — each with the evidence line it came from
- An understudy draft of the requested piece, written under that profile
- The couldn't-infer list: judgment calls the samples didn't cover, with the guess made and the question that would settle it
- A profile file the user can save and hand back next time (works with the Professional Brain convention)
Required Inputs
Ask for (if not already provided):
- 3–5 samples of the user's real work — ideally the same genre as the ask (their exec updates to draft an exec update), including at least one they're proud of and, if possible, one with visible edits or a decision they reversed
- The new piece to draft: audience, situation, what they want to happen
- Anything the samples predate: new role, new company, changed opinions
Process
- Study decisions, not diction. For each sample extract: what it leads with · what it conspicuously omits · where certainty lives vs where hedges live · how bad news is carried · what gets numbers and what gets narrative · the asks it makes and how bluntly. Note tone last.
- Write the profile in falsifiable lines. "Leads with the decision, then two reasons, never three" is checkable; "clear and concise" is horoscope. Every line cites its sample. Show the profile and invite corrections — corrections are the highest-value input this skill gets.
- Draft under the profile. Apply the decision patterns first, the voice second. Where the new piece demands a judgment the samples never made, make the closest-fit call, mark it inline with ⚠, and add it to the list.
- Deliver the couldn't-infer list. Each entry: the gap, the guess made, the one question that would close it. This list shrinking over sessions IS the apprenticeship.
- Offer the profile as a file (
understudy-profile.md) so the study cost is paid once.

Output Format
## How you think (from N samples — correct me)
[Falsifiable pattern lines, each citing its sample]
## The draft (as your understudy)
[The piece, ⚠ marks on inferred judgment calls]
## What I couldn't infer about you
| Gap | The guess I made | The question that settles it |
## Keep this
[The profile file, ready to save and reuse]Quality Checks
- Every profile line is falsifiable and evidence-cited — zero horoscope lines ("values clarity")
- The draft's ⚠ marks match the couldn't-infer list one-to-one
- At least one profile line captures something the user doesn't do — omissions are half of judgment
- With fewer than 3 samples, say the profile is thin and mark confidence accordingly rather than padding it
- The output invites correction explicitly — a profile the user never corrects is a profile that stopped learning
Anti-Patterns
- Do not do tone cosplay — matching vocabulary while inventing judgment is the exact failure this skill replaces
- Do not silently guess on uncovered judgment calls; the ⚠ + list is the contract
- Do not flatter the samples — if two samples contradict each other, surface the contradiction and ask which one is current
- Do not use the profile to impersonate the user to third parties without their framing — the understudy drafts FOR the principal, who remains the byline and the approver
Related
[[api-for-yourself]] is the outward-facing sibling (how others work with you); this is inward (how you think). Store the profile per the [[clone-brief]] and Brain conventions.

Study 3-5 samples of the user's real writing and decisions, build an explicit 'how you think' profile, then draft new work as their understudy — always with a 'what I couldn't infer about you' list so the gaps are visible instead of guessed.
When should I use The Understudy?
The Understudy fits situations like: someone says write it like I would; draft this as me; wants an AI that apprentices to their judgment rather than imitating their tone.
How do I install The Understudy in Claude Code?
Run `npx skills add mohitagw15856/pm-claude-skills --skill the-understudy -a claude-code`. Or copy the skill folder (skills/the-understudy in mohitagw15856/pm-claude-skills) into .claude/skills/the-understudy in your project. Claude Code loads it when a task matches its description.
