What it does

Case Study Writeup is an agent skill from mohitagw15856/pm-claude-skills. Write a client case study that sells future work — challenge, approach, results. Use when asked to write a case study, a client success story, a project write-up, or a portfolio case for consulting/agency work. Produces a results-led case study — the client & challenge, your approach, quantified outcomes, a client quote slot, and a takeaway — structured to win the next client. Ready to export as a designed PDF.

Its SKILL.md is about 940 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 Documents & Office. 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

  • Asked to write a case study
  • A client success story
  • A project write-up
  • A portfolio case for consulting/agency work

Example prompts

  • “/case-study-writeup”

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

Case Study Writeup loads about 936 tokens when it runs. Until then it costs about 108 tokens; SKILL.md has 475 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~108
When it runs · the whole SKILL.md, loaded when a task matches
~936

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.

Write a client case study that sells future work — challenge, approach, results.

Case Study Write-up Skill

A case study is your most persuasive sales asset — proof that you've solved this kind of problem before. Weak ones narrate activities; strong ones lead with a result, show the before→after, and make the reader (a future client) think "that's my problem too." This skill writes that — challenge → approach → quantified outcome — ready for the themed PDF export or a portfolio page.

Required Inputs

Ask for these only if they aren't already provided:

  • The client & context — who (or an anonymised descriptor — "a Series B fintech"), and their situation.
  • The challenge — the problem you were brought in to solve, and what was at stake.
  • What you did — your approach and the key moves (your contribution, specifically).
  • The results — outcomes with numbers (before → after); a client quote if you have one.

Output Format

Case Study: [outcome headline]

Headline — lead with the result, not the client ("Cut onboarding time 60% for a Series B fintech" — not "Acme Engagement"). It's the hook.

1. The client & challenge — who they are and the problem, framed so a similar prospect recognises themselves. The stakes (what it was costing them).

2. The approach — what you did and why — enough to show expertise and judgement, not a play-by-play. Highlight the insight or decision that mattered.

3. The results — quantified outcomes, before → after. Lead with the headline metric; add supporting ones. If numbers are confidential, use ranges ("~40% faster").

BeforeAfter

4. Client quote — a slot for a testimonial (with name/title/company if permitted) — third-party validation is the most persuasive line.

5. The takeaway — one line on the transferable lesson / what this proves you can do — pointing the reader toward their own version of the problem.

Note (for the user): get client sign-off before publishing; anonymise where needed; lead every section with outcome over activity.

Quality Checks

  • The headline is the result, not the project/client name
  • The challenge is framed so a similar prospect sees themselves in it
  • Results are quantified (before → after), with ranges if confidential
  • Your specific contribution is clear (not just "the team")
  • Includes a client-quote slot for third-party proof
  • Ends with a transferable takeaway that invites the next client

Anti-Patterns

  • Do not title it after the client/engagement — lead with the outcome; that's what pulls the reader in
  • Do not narrate activities without results — "we ran workshops" proves nothing; show what changed
  • Do not bury or omit the numbers — quantified outcomes are the whole point; use ranges if you must anonymise
  • Do not publish without client consent — confirm sign-off and anonymisation first
  • Do not blur your role into the team's — a prospect is hiring you; show what you did

Based On

Case-study / social-proof marketing practice — result-led headline, challenge–approach–outcome, quantified before→after.

Example Trigger Phrases

  • "Write a case study."
  • "Turn this project into a client success story."
  • "Write up this engagement for our portfolio."
  • "Show the results we got for this client."
