Engineering keeps building the wrong thing from our feature briefs. Turn this brief into a real functional spec.

CLAUDE · AS PERPETUO, REQUIREMENTS AND SPEC WRITER Perpetuo returns a functional spec with explicit inputs, outputs, edge cases and acceptance criteria, a list of open questions and assumptions flagged before build starts, and a versioned document traceable back to the decision that produced each requirement.

strategy consultant. client deliverables need to meet a high bar. this gets me to a usable first draft in a fraction of the time.

★★★★★ Karolina W. on Diane — Executive Assistant

product manager. used to spend too much time formatting and structuring. this gives me a consistent starting point every time.

What's inside this skill

Functional specs with explicit inputs, outputs, and edge cases
Acceptance criteria engineering can actually estimate against
Every open question and assumption flagged before build starts
Versioned specs traceable back to the decision behind them

Product managers and tech leads whose feature briefs keep getting misbuilt because the spec was never actually written.

A technical business analyst bills $100+/hr, the complete skill is yours forever.

// wat erin zit

What you're actually buying

Drop Perpetuo into Claude and get a requirements writer who turns a fuzzy feature ask into a spec engineering can build from without guessing.

Perpetuo owns the translation from a stakeholder's fuzzy ask into a spec engineering can actually estimate and build: functional requirements, explicit inputs and outputs, edge cases, acceptance criteria, and the open questions that would otherwise surface mid-sprint. He version-controls every spec and ties each requirement back to the decision that produced it, so nobody has to reconstruct intent from a Slack thread six months later. He is distinct from Reid, who writes reports on what happened, and from Theo, who analyzes existing documents — Perpetuo's lane is specifying what should be built, before it exists.

What you get

→Functional specs with explicit inputs, outputs, and edge cases
→Acceptance criteria engineering can actually estimate against
→Every open question and assumption flagged before build starts
→Versioned specs traceable back to the decision behind them

# Perpetuo - Requirements & Functional Spec Writer

You are Perpetuo, a Requirements & Functional Spec Writer. You turn a fuzzy feature idea into a spec engineering can actually build from.

## How you work
1. Extract the actual requirement from stakeholder conversation, not just the stated feature
2. Write functional specs with explicit inputs, outputs, edge cases, and acceptance criteria
3. Flag every open question and assumption before it becomes a build-time surprise
4. Keep specs versioned and traceable back to the decision that produced them

Not a substitute for engineering sign-off on feasibility and scope.

Vragen over dit product

What does the Perpetuo skill do?+

Turn a fuzzy feature brief into a functional spec engineering can build from without guessing. Load it once into Claude Projects and you get a configured Requirements & Functional Spec Writer without re-explaining context at the start of every session. This skill is not a substitute for engineering sign-off. Confirm every requirement and constraint against actual system behavior and stakeholder approval before development begins.

How do I install this skill file?+

Download the .skill package (it contains SKILL.md), paste the contents into Claude Projects Instructions or your AI's system prompt, add your own context and start your first session. Works with Claude, ChatGPT, or any AI chat that accepts system prompts.

Which AI tools does this skill work with?+

Works with Claude (recommended), ChatGPT, Gemini, Perplexity and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results.

What is included in this download?+

One .skill package delivered instantly after purchase: the full SKILL.md role configuration plus a worked-example file with a real scenario so you see the quality before you rely on it. No subscription, yours permanently.

How is this different from using Claude without the Perpetuo skill?+

Without a skill file your AI starts every session as a general assistant. With Perpetuo loaded it applies Requirements & Functional Spec Writer methodology from the first message, with consistent quality every time. This skill is not a substitute for engineering sign-off. Confirm every requirement and constraint against actual system behavior and stakeholder approval before development begins.

Do I have to read it myself?+

No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.

Is this a physical book?+

No, it's digital. You download it the moment the order goes through and it's yours permanently. The cover is styled like a book because each edition is written and edited as one self-contained piece of work. The reading part is your AI's job, not yours.
