Project to Marp

Create a Marp presentation introducing the current project with minimal user effort.

Language

Write the presentation in the same language as the user's request/conversation, unless the user specifies otherwise.

Workflow

1. Read Context

Before anything else, check the current conversation for clues about the user's intent — what they want to communicate, to whom, or any constraints already mentioned.

2. Quick Survey

Do a lightweight survey — just enough to ask informed questions:

• README, package.json / pyproject.toml / equivalent
• Top-level directory structure

3. Clarify (Keep It Short)

Only ask what cannot be reasonably inferred. Ask all questions in a single message.

Ask using AskUserQuestion (multiple choice) when options are clear:

• Presentation length: "5 min (5–7 slides) / 10 min (10–12 slides) / 15 min (15–18 slides)"
• Audience: "Developers / Non-technical stakeholders / Mixed / Other"

Always ask about purpose / key message — choose the form based on how much you can infer:

• If the user's intent feels sufficiently clear from context, propose your inferred message as options using AskUserQuestion (e.g. "Does this capture what you want to convey? / Something else")
• If intent is unclear or thin, make your best guess as a suggestion and ask as freeform: "I'm thinking something like '…' — what's the one thing you most want the audience to take away? (Don't worry about organizing — just write whatever comes to mind)"

The audience question can be skipped if clearly inferable.

4. Deep Exploration

After receiving the user's answers, thoroughly explore the project to understand it well:

• Key source files, core logic, architecture
• Docs, comments, examples
• Any unique or interesting aspects worth highlighting

Take time here — a well-understood project leads to a much better presentation.

5. Design Two Storylines

Based on the user's answers and your deep exploration, design two distinct storyline proposals — think of them as two different angles or narratives for the same project. Each proposal should have a different structure, emphasis, or rhetorical flow. For example:

• Proposal A: Problem-first — open with the pain point, then reveal the solution
• Proposal B: Vision-first — open with the end result or impact, then explain how

Other possible contrasts: technical depth vs. business value, chronological story vs. feature-driven, demo-first vs. theory-first. Choose contrasts that make sense for the project and audience.

Do not ask the user to choose — generate slides for both.

6. Create Both Presentations

Generate two .md files in the project root:

• presentation-a.md — Proposal A
• presentation-b.md — Proposal B

Structure per proposal (adjust based on storyline angle):

1. Title slide — project name + one-line description
2. Problem / Background — why this project exists
3. Solution / Overview — what it does
4. Key Features — 2–4 highlights, one idea per slide
5. Architecture / How It Works — diagram or bullet overview (if technical audience)
6. Demo / Usage — example commands, screenshots, or code snippets
7. Summary + Next Steps / Call to Action

Writing style:

• One idea per slide
• Bullet points: max 5–6 per slide, each ≤ 15 words
• Title slides and section dividers: use <!-- _class: lead -->
• Keep content concise to avoid text overflow — when in doubt, cut rather than squeeze

For Marp syntax, see references/marp-syntax.md.

7. Export (if Marp is installed)

Check if Marp CLI is available:

marp --version

If available, export both presentations to HTML:

marp --no-stdin --allow-local-files presentation-a.md -o presentation-a.html && marp --no-stdin --allow-local-files presentation-b.md -o presentation-b.html

If Marp is not installed, inform the user and suggest: npm install -g @marp-team/marp-cli

8. Explain Both Proposals

After generating both presentations, explain them to the user in a single message:

• Proposal A (presentation-a.md): describe its storyline angle, opening hook, and what kind of audience or occasion it suits best
• Proposal B (presentation-b.md): same breakdown
• Briefly note the key difference between the two, and let the user know they can use either as-is, ask for revisions, or merge elements from both
