What it does

Portfolio Case Study Writer is an agent skill from davila7/claude-code-templates. Transform resume bullets into detailed portfolio case studies with context, action, and outcome. Use when the user mentions portfolio, case study, project write-up, or expanding a resume bullet into a longer narrative.

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 Business, Finance & HR. The repository describes itself as: CLI tool for configuring and monitoring Claude Code. The licence is MIT.

When your agent uses it

  • The user mentions portfolio
  • Project write-up
  • Expanding a resume bullet into a longer narrative

Example prompts

  • “/portfolio-case-study-writer”

Workflow steps

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

  1. Overview Section
  2. Problem Section
  3. Process Section
  4. Solution Section
  5. Results Section
  6. Learnings Section

What it can do on your machine

Read from SKILL.md and the folder at commit c0ca7da. 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

Portfolio Case Study Writer loads about 2.3k tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 448 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~62
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.

When to Use This Skill

Use this skill when the user:

  • Wants to create portfolio case studies
  • Needs to expand resume bullets into detailed writeups
  • Is building a portfolio website
  • Wants to showcase project work in depth
  • Mentions: "case study", "portfolio", "project writeup", "work samples", "portfolio piece"

  • Differentiate you from other candidates
  • Required for many PM, UX, and creative roles

The Case Study Structure

Standard Structure
1. Overview (Project summary)
2. Problem (What needed to be solved)
3. Process (How you approached it)
4. Solution (What you created/delivered)
5. Results (The impact)
6. Learnings (What you'd do differently)
Time to Read
  • Quick Read: 3-5 minutes (essential for portfolio)
  • Deep Dive: 10-15 minutes (for interested readers)

Section-by-Section Guide

1. Overview Section

Purpose: Hook the reader, provide context

Include:

  • Project name and company
  • Your role
  • Timeline
  • Team size
  • One-sentence summary of impact

Example:

# Redesigning the Checkout Flow

**Company:** E-Commerce Inc.
**Role:** Lead Product Designer
**Timeline:** 6 weeks
**Team:** 2 designers, 3 engineers, 1 PM

**Summary:** Reduced cart abandonment by 35% through a streamlined 3-step checkout process, generating $2M in recovered revenue.
2. Problem Section

Purpose: Set up why this work mattered

Include:

  • Business context
  • User pain points
  • Key metrics or goals
  • Constraints

Example:

## The Problem

E-Commerce Inc. was experiencing 68% cart abandonment—significantly higher than the industry average of 55%. Exit surveys and user research revealed several issues:

- **Too many steps:** Our checkout had 7 screens
- **Forced account creation:** Users had to register before purchasing
- **Hidden costs:** Shipping wasn't shown until step 5
- **Mobile friction:** Forms weren't optimized for mobile

**Goal:** Reduce cart abandonment to below 50% within 3 months.

**Constraints:**
- No changes to existing payment integrations
- Had to maintain PCI compliance
- 6-week timeline before holiday season
3. Process Section

Purpose: Show your thinking and methodology

Include:

  • Research conducted
  • Stakeholders involved
  • Hypotheses formed
  • Options considered
  • Decisions made (and why)

Example:

## Process

### Research
I started by understanding the problem deeply:
- Analyzed Mixpanel funnel data for drop-off points
- Conducted 10 user interviews with recent abandoners
- Reviewed heatmaps and session recordings
- Benchmarked against 5 competitor checkout flows

**Key Insight:** 73% of drop-offs occurred at the account creation screen. Users wanted to purchase, not commit to a relationship.

### Ideation
I explored several approaches:
1. Guest checkout only (simplest)
2. Social login options (lower friction)
3. Progressive profiling (collect info over time)
4. One-page checkout (Amazon-style)

After weighing feasibility, timeline, and impact, we chose a hybrid approach...

### Decisions Made
- **Guest checkout first:** Made registration optional and post-purchase
- **Transparent pricing:** Showed shipping on the first screen
- **Mobile-first design:** Designed for mobile, then adapted for desktop
- **Progress indicator:** Added clear "Step 1 of 3" indicator
4. Solution Section

Purpose: Show what you actually created

Include:

  • Visual artifacts (mockups, screenshots, diagrams)
  • Key features/changes
  • Technical implementation (if relevant)
  • How it addressed the problems

Example:

## Solution

### The New Checkout Flow

**Before:** 7 screens with mandatory registration
**After:** 3 screens with optional guest checkout

[IMAGE: Before/After comparison]

### Key Changes

**1. Transparent Pricing Widget**
[IMAGE: Pricing widget mockup]
Showed order total, shipping, and taxes from the start. No surprises.

**2. Guest Checkout Option**
[IMAGE: Guest checkout screen]
Made account creation optional with clear value proposition for why to register.

**3. Smart Form Design**
[IMAGE: Form design]
- Single-column layout on mobile
- Auto-format for phone/card numbers
- Address autocomplete integration
- Clear error messaging

**4. Trust Signals**
Added security badges, money-back guarantee, and customer service contact throughout the flow.
5. Results Section

Purpose: Prove impact with data

Include:

  • Quantitative results (with timeframe)
  • Comparison to goals
  • Secondary metrics affected
  • Business impact

Example:

## Results

### Primary Metrics (90 days post-launch)

| Metric | Before | After | Change |
|--------|--------|-------|--------|
| Cart Abandonment | 68% | 44% | -35% |
| Checkout Completion | 32% | 56% | +75% |
| Mobile Conversion | 18% | 41% | +128% |
| Revenue per Visitor | $2.40 | $3.85 | +60% |

### Business Impact
- **$2M additional revenue** in first quarter
- **15% increase in mobile orders**
- **Customer support tickets about checkout** dropped by 45%

### Secondary Effects
- Account creation actually increased 20% (post-purchase)
- Average order value stayed stable
- Return customer rate improved

6. Learnings Section

Purpose: Show growth mindset and self-awareness

Include:

  • What worked well
  • What you'd do differently
  • Unexpected challenges
  • Skills developed

Example:

## Learnings

### What Worked
- **Early user research** prevented us from building the wrong solution
- **Cross-functional alignment** meetings kept everyone on the same page
- **Launching with analytics** let us measure impact immediately

### What I'd Do Differently
- **More A/B testing:** We launched the full redesign at once. Would have preferred to test individual changes to understand what drove results.
- **Earlier mobile focus:** We designed desktop-first then adapted. Starting mobile-first would have been more efficient.
- **Stakeholder education:** Spent too long convincing leadership. Would start stakeholder alignment earlier next time.

### Skills Developed
- Advanced Figma prototyping
- Working with A/B testing frameworks
- Presenting data-driven design decisions to executives
