Warmth Threads · Pull-Down Thread

v1 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

An in-feed accordion where tapping a card's warmth strip expands it downward into a full chat-bubble memory thread without leaving the inbox.

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 PULL-DOWN THREAD — 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 — a warm vertical thread of past touches so you remember who someone is before you triage them.

YOUR ANGLE — IN-FEED DOWNWARD ACCORDION:
Render a sticky header with pressure context ('Tuesday · 6 people need you'), then a debt-ranked feed of 4-5 person-cards. Each resting card shows: heat edge (left border colored by --urgent/--warm/--cold), a monogram circle, name in Fraunces, one context/debt line ('9 days quiet · $40k renewal'), and a thumb-zone triage verb chip. The ONLY new chrome on a resting card is a thin 'warmth strip' along the card's bottom edge: a row of 4-6 tiny dots in heat colors, a small label ('5 threads · since Mar 24'), and a downward chevron.

Tapping the strip (CSS checkbox + :checked sibling selector — same mechanic as v1's diff flip) expands THAT card downward IN PLACE via a max-height transition, growing it to ~3x height and pushing the cards below it down. No modal, no page nav. The revealed Thread is a warm vertical timeline with a 2px connecting gutter line drawn via ::before. Each entry: a date stamp in muted Fraunces ('Mar 14'), a small glyph chip (☎ call, ✉ note, ◆ meeting, ♡ personal), and one line of remembered context ('Closed the renewal over coffee — she brought her dog.' / 'Promised to intro her to Priya.' / 'Kids piano recital — wished her luck.'). PERSONAL entries get a faint amber wash + a heart tick on the gutter so human memories rise above transactional ones. The oldest entry fades toward the parchment bg via an opacity gradient. At the bottom: a single sage Fraunces line 'You've tended Maria for 14 months.' The triage verb chip stays pinned/visible the whole time.

HONEST PROOF STATE: author ONE card pre-expanded (its checkbox checked by default) showing a full 5-entry thread with one glowing amber personal memory; leave the other cards collapsed to their warmth strips, each tappable to expand via :checked.

PALETTE (scope to .tnd-app, NOT :root): --bg:#faf7f2; --bg2:#f4eee4; --card:#fffdf9; --ink:#2b2622; --ink2:#6f675e; --ink3:#9b9288; --line:#ece4d7; --cold:#6b8cae; --warm:#e0a23b; --urgent:#e06a5b; --green:#3da06b; --accent:#2f9e8f; --accent-soft:#dff0ed.

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-'.
