Warmth Threads · Memory Lane

v3 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 full-screen immersive memory view that slides up per person via :target, turning the thread into a quiet reading room for reminiscing rather than an inline list.

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 MEMORY LANE — 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 warm conversation history underneath Tend's debt line, so you remember who someone is before triaging them.

YOUR ANGLE — FULL-SCREEN IMMERSIVE :target READING ROOM:
Instead of an inline accordion, the thread is a dedicated full-bleed view. The base layer is the normal Tend inbox: sticky pressure-context header + a debt-ranked feed of person-cards (heat edge, monogram, Fraunces name, debt line, triage verb), each with a small 'remember' affordance (♡). Tapping a card is an <a href='#person-maria'> that targets a full 375×720 overlay panel which slides up over the feed (position:absolute, transform: translateY(100%) → 0 on :target, transition).

The overlay is an emotional reading room, NOT a cramped list: a large Fraunces name + monogram up top, a generous calm warmth thread below with lots of whitespace — each memory entry gets room to breathe (date in Fraunces, glyph ☎ ✉ ◆ ♡, a full remembered-context sentence). PERSONAL memories are the visual centerpiece: bigger, amber-washed, slightly larger type — the human moments dominate the page while transactional ones recede in muted ink3. The oldest memories fade toward bg. Near the bottom, the hero sage Fraunces line 'You've tended Maria for 14 months.' A back affordance (href='#feed') slides the overlay back down. Pin the triage verb at the bottom of the overlay so you can act after reminiscing.

Use :target as the state engine. Build at least 2 distinct person overlays (e.g. Maria, Priya) each with its own #id and its own thread content, plus a default feed state, so tapping different cards opens different memory rooms. This is the variant that prioritizes EMOTION and READING — make it feel like opening a letter, not scanning a log.

HONEST PROOF STATE: default load shows the feed; document that tapping a card opens that person's overlay. Optionally hard-open one overlay via the URL hash being present in markup is not possible without JS, so instead make tapping reliable and show the overlay fully styled.

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-'.
