name: portfolio-page description: "Structure a portfolio or case-study page that shows your work, not just lists it. Use when asked to write a portfolio page, a project case study, a work showcase, or an 'is this person good?' proof page. Produces a portfolio structure — a positioning header, and per-project case studies (context → your role → what you did → outcome) that demonstrate impact, ready to export as a designed page/PDF."

Portfolio Page Skill

A portfolio fails when it's a gallery of artifacts with no story — the viewer can't tell what you did or whether it worked. This skill structures it as evidence: a clear positioning header, then per-project case studies that walk context → your specific role → what you did → the outcome. It works for PMs, designers, engineers, marketers, founders — any "show me you're good" page.

Required Inputs

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

• Who you are & what you want — your positioning and the audience (hiring manager, client, investor).
• The projects — 2–4 of your best, with: the problem, your role, what you did, and the result.
• Proof — metrics, links, visuals, testimonials (whatever's available).
• Constraints — anything confidential/NDA that needs anonymising.

Output Format

[Name] — [positioning headline]

One line on who you are and the value you create; who the page is for; contact/links.

Selected work — 2–4 case studies, strongest first. Each:

[Project name] — [one-line outcome]

• Context: the situation and the problem (brief — set the stage).
• My role: your specific contribution vs. the team's (be honest and clear).
• What I did: the key decisions/actions, not every task — show judgement.
• Outcome: the measurable result (or qualitative if that's all there is), and what you learned.
• Proof: link / visual / metric / quote.

About / how I work (optional) — a short note on approach or values, for fit.

Note (for the user): pick depth over breadth — 3 strong case studies beat 8 thin ones. Anonymise confidential numbers as ranges ("~30% lift") rather than dropping them.

Quality Checks

• Each project is a case study (context → role → action → outcome), not just a title + screenshot
• Your specific role is distinguished from the team's on every project
• Outcomes are stated (quantified where possible), not left implied
• The page leads with positioning so the viewer knows who it's for and what you do
• 2–4 strong projects, newest/most-relevant first — depth over breadth

Anti-Patterns

• Do not list artifacts without the story — a screenshot with no context proves nothing
• Do not blur your contribution into the team's — "we shipped" leaves the viewer unsure what you did
• Do not omit outcomes — "redesigned the flow" without a result is a task, not a case study
• Do not pad with weak projects — each extra mediocre one dilutes the strong ones
• Do not leak confidential data — anonymise to ranges instead of dropping the impact entirely
