HermesShare cards

Use this skill with a checkout of time-attack/HermesShare. Run commands from the repository root, or set HERMESSHARE_REPO and pass --repo explicitly. Dependencies are listed in requirements-cards.txt. Native preview additionally needs macOS, Xcode, XcodeGen and a booted simulator. Never assume this skill directory itself contains a complete app checkout.

Default workflow

1. Retrieve current facts from their authoritative source. Distinguish source materials from

inferred explanations. Never reuse a previous card's facts merely because its design fits.

1. Reuse an established native architecture. State the card's question, visual metaphor,

emotional temperature and structural stage. fast_card.py --describe notebook or --describe taskboard provides a compact reusable design/input contract.

1. Write fresh content input instead of rebuilding wrappers and drawing code. For another

native layout, use --layout-file; for weekly schedules use make_schedule.py.

1. Prepare and inspect fresh native renders:

python3 scripts/fast_card.py --template notebook --input content.json \
  --repo "$PWD" --out-dir .build/my-card --preview --all-tabs --simulator YOUR_UDID

1. Verify original facts, payload size, readable labels and the relevant controls/states.

Then send once through the provider and existing conversation selected by the user. For Linq, prefer send_card.py --chat-id over creating/reselecting a chat with --to.

See docs/fast-native-preview.md, docs/learning-components.md, docs/schedule-composer.md and docs/SENDING.md. scripts/capabilities.py reads the actual current native vocabulary.

Guardrails

• The bubble is a text-free graphic thumbnail, not a squeezed full card. Keep interactive:false

for Linq and live:false for Photon. Native controls still work after expansion.

• Use real HTTPS image URLs. Upload privately through the chosen provider, never GitHub Pages.
• Cache layout compilation, graphics, verified private downloads and native app builds. Do not

cache source truth, new screenshots, real sends or delivery results. Every card validates fresh.

• Ordinary content updates should not trigger a full Xcode build/test cycle or a new thumbnail

script. Native component changes and new interaction architectures require full affected tests.

• Root-tab alternate-state screenshots are not proof of actual taps. Host screenshots are not

proof that the Messages extension launched on the recipient's physical phone.

• Stop/relaunch Messages around phone app installation, verify the current extension bundle path,

and open a real received card. A receipt alone is insufficient.

• Do not invent live/current/completed states for a recurring weekly schedule. Preserve full

course names, instructors, sections, rooms and times as accessible native text.

• Never print credentials, presigned upload URLs, raw encoded payloads or private card contents.

Do not automatically duplicate a message whose delivery is still pending.
