Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00032 | $0.00805 |
| Opus 5 | $0.00016 | $0.00402 |
| Sonnet 5 | $0.00006 | $0.00161 |
| Haiku 4.5 | $0.00003 | $0.00081 |
Grade A, and why
portfolio-case-study scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Portfolio Case Study
Trigger
Use when the user wants to create case studies, build a portfolio, or design a creative resume that balances visual appeal with ATS compatibility.
Keywords: "case study", "portfolio case study", "portfolio", "write case study", "creative resume", "designer resume", "UX portfolio", "product design portfolio", "project writeup", "portfolio piece", "case study template", "design resume", "project showcase", "work samples", "portfolio website content", "how to write a case study"
Part 1: Case Studies
Structure
- Overview — project name, your role, team, timeline, one-sentence impact
- Problem — business context, user pain points, constraints, success metric
- Process — research, options considered, key decisions and rationale
- Solution — what you built/delivered, key features, how it solved the problem
- Results — quantified outcomes (before/after table), business impact
- Learnings — what worked, what you'd do differently
Target: 3-5 minute read.
Depth by Role
- Product Manager: strategy, prioritization, stakeholder alignment, metrics
- UX/Product Designer: user research, design iterations, usability testing
- Software Engineer: architecture decisions, trade-offs, system design
- Marketing: channel strategy, targeting, creative, attribution
Visual Elements
Must-have: before/after comparisons, key deliverable screenshots, results chart. Always: blur sensitive data, add captions, size for mobile.
Part 2: Creative Resume Strategy
Two-Version Approach
ATS version (online applications):
- Single column, standard fonts, no graphics
- Show creativity through: clean typography hierarchy, strategic white space, strong writing
- Safe touches: subtle color in headers, hyperlinks to portfolio, clean dividers
Designed version (portfolio, networking, direct outreach):
- Your resume IS a design sample
- Consistent with portfolio site visual identity
- 2-3 colors max, 2 font families, clear hierarchy
- Must still be scannable in 6 seconds
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 11d ago First seen · 115 lines · 32 tokens per session scan A b24bee1743e3
portfolio-case-study is a skill published in the GitHub repository art2url/career-agent-skills (8 stars, last pushed 5mo ago), licensed MIT. It adds 32 tokens to every session and 805 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
