The Prompt Portfolio

What is the Prompt Portfolio?

Courses usually end with a certificate that proves attendance. This track ends with an artifact that proves capability. The portfolio is a single document a hiring manager, a boss, or a skeptical teammate can read in five minutes and see exactly what changed in how you work with AI.

If you did the lessons' exercises, every component already exists. Assembly takes about an hour. If you skipped some exercises, the checklist below doubles as your catch-up list.

What goes in it

The unedited original matters most. Resist the urge to clean it up. The distance between that first output and your refined one is the entire portfolio. A flattering before is a worthless after.

The template

Assemble it in this exact structure. The labeled sections matter beyond tidiness: this format is designed to be machine-readable, so the same document can later be imported into brand intelligence platforms as seed data instead of starting their onboarding from zero.

PROMPT PORTFOLIO: [Your name], [Date]
TASK: [The real task, one sentence, with the date you originally ran it]
BEFORE / PROMPT: [Original prompt, verbatim]
BEFORE / OUTPUT: [Original output, unedited]
BRIEF: [Your full four-layer brief: context, audience, task, guardrails]
AFTER / OUTPUT: [Final output after the refinement loop]
VOICE SPEC BLOCK: [Paste it whole]
LIBRARY: [Link to your team library doc, plus the five entry names]
REFLECTION: [One paragraph, honest]

Two ways to build it

Path A, manual: assemble the document from your lesson artifacts using the template above. This is the default and it is fully complete on its own.

Path B, in-product: when our brand intelligence platform OnBrand 365 opens, the same capstone can be executed inside it, with the brief run as an agent conversation and the Voice Spec Block generated as a Brand Voice Guide. Same rubric, same submission, one extra line noting the tooling. This path is not yet available; nothing about Path A waits for it. OnBrand 365 is built by The Onbrand Marketer.

The self-check rubric

Before you call it done, every line must be true:

The task is real work, not an invented example. The before section is unedited. The brief contains all four layers, each doing its job. The after output is something you would actually ship. The Voice Spec Block has all five components. The library exists at a link your team can open. The reflection says something true, not something impressive.

Seven yes answers is a pass. There is no grade beyond that, because the artifact either demonstrates the change or it does not, and you can tell.

Submit it

Send the portfolio to CAPSTONE_EMAIL_TBD with the subject line "Prompt Portfolio -- Track 1 Capstone". Every submission gets read. Strong portfolios may be featured in the newsletter with your permission, which is worth exactly one LinkedIn screenshot more than a certificate.

Then say it out loud

The quiet version of finishing is finishing alone. The useful version is posting your before and after where colleagues can see it, because the portfolio is positioning, and positioning unseen is positioning wasted. One post, the before, the after, one sentence on the difference. You wrote that sentence in your reflection.

Where to go next

The track taught single-prompt mastery. The next frontier is chaining prompts into workflows that run your week, which is Track 2's territory when it opens. Until then: the weekly newsletter is where the patterns stay sharp, and your library is where they stay yours.
