v2 Opus 4.8 Fully Autonomous

high Claude Code autonomous

Purpose

A variant of Warmth Threads for Tend — the conversation history beneath the unread/debt line, so you remember who someone is before you triage them. Part of a 5-variant autonomous research series.

Variant Focus

A 3D card-flip where the debt face turns over to reveal the warmth thread on its reverse side, making 'what you owe' and 'why they matter' two faces of one object.

Prompt

This version was generated autonomously by a sub-agent in a fully-autonomous origination round. The prompt below is the exact prompt given to the build agent — crafted by the orchestrating workflow from the OG master prompt and the ideation phase.

Build a standalone Tend variant called THREAD FLIP — one of 5 interpretations of the Warmth Threads feature. NO JavaScript. Pure HTML/CSS only. Exactly 375×720, mobile-only, wrapped in .tnd-app.

FEATURE: Warmth Threads adds the conversation history underneath Tend's unread/debt line — past touches so you remember who someone is before you triage them. It is the mirror image of debt: one face is 'what you owe,' the other is 'why they matter.'

YOUR ANGLE — 3D CARD FLIP (front=debt, back=warmth):
Make the metaphor literal: each person-card has TWO faces. The FRONT is the standard Tend debt face: heat edge, monogram, name in Fraunces, debt line ('9 days quiet · $40k renewal'), triage verb. A small 'flip to remember' affordance sits in a corner (a ♡ + chevron). Tapping it (CSS checkbox + :checked driving a transform: rotateY(180deg) on an inner wrapper, with transform-style: preserve-3d and backface-visibility: hidden) flips the card over to reveal the BACK: the warmth thread.

Because the back must fit the same card footprint, design the thread as a COMPACT scrollable memory list within the flipped card (overflow-y on the back face, scroll-snap optional): date in muted Fraunces, glyph chip (☎ ✉ ◆ ♡), one remembered-context line. PERSONAL entries amber-washed and visually elevated above transactional ones. A sage Fraunces line at the bottom of the back: 'You've tended Maria for 14 months.' A 'flip back' control returns to the debt face. The triage verb should remain accessible — keep it on the back face too, pinned at the bottom, so you can act with the memory fresh.

Get the 3D right: perspective on the card container, the inner wrapper rotates, both faces absolutely positioned and stacked. The flip should feel like turning a real card. Only ONE card needs to be a full working flip demo; show 3-4 other resting debt-face cards in a short feed above/below it (with a sticky pressure-context header) so it reads as an inbox.

HONEST PROOF STATE: author the hero card so it can flip both directions via :checked; optionally show one secondary card pre-flipped to its warmth back so a reviewer sees both faces at once.

Orchestrated the autonomous origination workflow: 3 feature scouts → author → 5 parallel builders → assembly.

Author 38s high Opus 4.8

Chose the Warmth Threads feature and wrote the OG master prompt + 5 distinct variant build-prompts.

Prompt ↓

Full Prompt

You are the Lead of an autonomous origination round for Tend (mobile-only pure-CSS relationship-inbox CRM). Three new-feature proposals were generated in parallel (The Drift Tide, The Daily Round, Warmth Threads). Pick the single strongest feature, then (1) write the verbatim OG MASTER PROMPT that spawns 5 parallel variants of that ONE feature, and (2) define 5 genuinely DISTINCT design/interaction interpretations, each with a concept name, distinguishing angle, one-sentence Variant Focus, and a complete self-contained build prompt (handed verbatim to its builder). featureName must be kebab-case starting with 'tend-'.
