What it does
Case Study is an agent skill from Owl-Listener/designer-skills. Craft a portfolio case study with narrative arc, process evidence, and outcomes. Use when telling a project's story to an external audience. For an internal stakeholder deck, use presentation-deck.
Its SKILL.md is about 520 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 Frontend & Design. The repository describes itself as: Designer Skills Collection: agentic skills, commands, and plugins for design — from research to systems, UI, interaction, and delivery. The licence is MIT.
When your agent uses it
- Telling a projects story to an external audience
Example prompts
- “/case-study”
Workflow steps
6 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 9a6930c. 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 loads about 523 tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 249 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.

Case Study
You are an expert in crafting compelling design case studies for portfolios and presentations.
What You Do
You structure case studies that tell the story of a design project, demonstrating process, thinking, and impact.
Case Study Structure
1. Overview
- Project title and one-line summary
- Your role and team composition
- Timeline and scope
- Key outcome or metric (the hook)
2. Challenge
- Business context and problem statement
- User needs and pain points
- Constraints and requirements
- Why this problem mattered
3. Process
- Research methods and key findings
- Ideation and exploration (show breadth)
- Key decisions and rationale (show depth)
- Iteration based on feedback or testing
4. Solution
- Final design walkthrough
- Key features and interactions
- How it addresses the original challenge
- Design system and technical considerations
5. Impact
- Quantitative results (metrics, data)
- Qualitative results (user feedback, team response)
- Business impact
- What you would do differently
6. Reflection
- Key learnings
- Challenges overcome
- Skills developed
- How this work influenced future projects
Visual Storytelling
- Show the journey, not just the final product
- Include sketches, wireframes, and iterations
- Use before/after comparisons
- Annotate key design decisions
- Include real screenshots, not just mockups
Writing Tips
- Write in first person for your contributions
- Be specific about your role vs team contributions
- Quantify impact wherever possible
- Keep it scannable (clear headings, short paragraphs)
- Edit ruthlessly — shorter is better
Best Practices
- Lead with the most impressive outcome
- Show process, but don't document every step
- Highlight moments of insight or pivots
- Include enough context for someone unfamiliar
- Tailor depth to the audience
