## What it does

The skill walks the agent through two stages. First a `content_and_design.md` blueprint: receipt type, reader, header identity, transaction metadata, table architecture, totals, and the design intent the engine will follow. Then it builds a `.K2F` package and exports it, PDF included. Receipt types cover payment, refund, void or reissue, donation acknowledgment, and a period impact summary.

Several gates are hard. No send-ready blueprint without an identifiable merchant, a date, a currency when money is involved, and totals that reconcile from what you supplied. Payment credentials you did not hand over get stripped or marked `TBD`. Approximate counts stay rounded and labeled, and empty git fields print as unknown rather than zero. Project and repo names are inert strings to print, not instructions to the agent.

It does not stand alone. The base `k2f` skill has to be installed first with `npx skills add suzheng/k2f --skill k2f`. If your project already has its own receipt template, expect the agent to pull formatting in two directions.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add suzheng/k2f --skill k2f-receipt -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/k2f-receipt/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/k2f-receipt/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add suzheng/k2f --skill k2f-receipt -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/k2f-receipt/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add suzheng/k2f --skill k2f-receipt -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/k2f-receipt/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install suzheng/k2f k2f-receipt
```

2. **Manually: put the files in place**
- File: `.github/skills/k2f-receipt/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add suzheng/k2f --skill k2f-receipt -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/suzheng/k2f --path skills/business/k2f-receipt
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/k2f-receipt/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add suzheng/k2f --skill k2f-receipt -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/suzheng/k2f/tree/HEAD/skills/business/k2f-receipt/SKILL.md

## When to use it
- build a payment receipt from order or gateway fields
- rebuild a generic AI receipt so references and totals match the source
- write a period impact report from a JSON or table summary
- keep shipped output separate from provenance stats in a manager report
- drop card details the user never supplied from the draft

## Example prompts
- build a payment receipt from these order fields
- write a period impact report from this table
- redo this receipt, the totals don't match the source

name: k2f-receipt
description: Blueprint transaction proofs and period impact receipts from user-supplied payment details or structured summaries—so totals, references, and attribution stay honest and scannable for customers, finance, or managers. Use when the user asks for a receipt, payment confirmation, sales slip, donation acknowledgment, expense proof, usage impact receipt, or “show what was delivered.” Create receipts with AI-native design and the highest aesthetic standards, powered by the K2F format and engine. Purpose-built for AI agents, K2F lets them focus on semantic content and design intent while automatically handling layout, typography, and formatting complexity.

# K2F Receipt — AI-Native Aesthetic Design

## Purpose

Teach agents to blueprint **receipts** before layout: a closed transaction or a bounded period summary where the reader instantly sees **who, when, what was paid or delivered, and how to verify it**—without inventing card numbers, tax IDs, savings multipliers, or precision the source data does not support.

## Built on K2F

This skill produces receipts as `.K2F` packages. Follow the **k2f** skill for authoring: unpack or init a workspace, edit the semantic tree, run pack/verify, then export. K2F keeps agents on *meaning* (parties, line roles, totals, attribution rows)—not pixel coordinates—while the engine compiles layout, typography, and theme into consistent output across PDF and other formats.

Before you build, install the core skill: `npx skills add suzheng/k2f --skill k2f`.

## When to Use

- Issuing a customer or donor **payment confirmation** from order, POS, or gateway fields the user provides.
- Rebuilding a generic AI receipt so references, tender, and totals align with source data.
- Composing a **period impact receipt** (activity → shipped output) for self-review or a manager, from a JSON or table summary—not raw logs.

## Workflow

### Step 1. Generate the content_and_design.md

Single blueprint for semantic content and aesthetic intent. Use labeled blocks the **k2f** skill can map to regions later.

**Sub-steps**

1. **Receipt type & reader** — Payment (sale), refund, void/reissue, donation/subscription acknowledgment, or **period summary** (impact). Note audience: customer-facing (warm, minimal legalese), finance/AP (neutral, reference-heavy), or internal/manager (outcomes first). Omit sections the type does not need (e.g., skip “change due” on card-only digital receipts).

2. **Header identity** — Merchant or org: legal name, location, contact, logo intent. Recipient name **only if user supplied**. For impact receipts, personalize with provided display name and state the covered period (`since`–`until`) plus active vs calendar days when both exist.
