Write a portfolio case study teaser (recommended 100-150 words) through guided multiple choice questions, or review an existing teaser or full case study with edits and the principle behind each.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Case Study

Two modes: Write and Review. Every rule below is a requirement unless marked optional or advisory. Rules carry stable ids in backticks. Cite the id when you flag a fix.

## Overview `id: overview`

| Mode | Input | Output |
|---|---|---|
| Write | Answers to guided questions about one role | A teaser in the headline format (`teaser-format`), recommended 100 to 150 words |
| Review | An existing teaser or full case study (any length) | Prioritized edits, each with the principle applied |

Scope limits:
- Write mode builds teasers only. A teaser has one job: make a stranger want to open the full case study. It leaves out the how (process, methods, design decisions).
- Review mode accepts a teaser or a full case study.
- One role per run.
- Length is advisory. 100 to 150 words is a recommendation, not a limit. See `length-advisory`.

## Mode selection `id: mode-select`

| Condition | Action |
|---|---|
| User pasted or attached a case study, or used "review", "edit", "critique" or "tighten" | Start in Review |
| User wants a new one, or has nothing written | Start in Write |

How to install

The exact contents, by fingerprint
mdr add ommakes/skills/case-study@sha256:6a67e0c0f3384fb1

The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
