Claude Code Project Instructions

Repository

  • Primary remote: origin = HIEofOne/self (all PRs and pushes go here)
  • Upstream fork: upstream = agropper/self (do NOT push or create PRs here without explicit permission)
  • When creating PRs, always use --repo HIEofOne/self

Branching

  • Feature branches: claude/<short-description>
  • PRs target main

Version Bumping

  • A pre-commit hook (scripts/pre-commit-version-bump.sh) auto-increments the patch version in package.json when server/ or src/ files are staged
  • Do not manually bump versions unless doing a minor or major release

Stack

  • Frontend: Vue 3 (SFC, Composition API), Vite, TypeScript for utilities
  • Backend: Express.js (ESM), CouchDB/Cloudant, DigitalOcean GenAI agents + Spaces (S3)
  • Auth: Passkey/WebAuthn with temporary (no-passkey) user fallback
  • Local storage: File System Access API (primary, Chrome 122+), PouchDB/IndexedDB (fallback)

Key files

Line counts as of v1.5.79 (July 2026); whole repo ≈ 62,000 lines (src/ 34,216 + server/ 27,378 + scripts/ 645).

  • server/index.js — main backend (~14,100 lines)
  • src/components/ChatInterface.vue — wizard, chat UI (~10,000 lines)
  • src/components/MyStuffDialog.vue — Workbook: saved files, patient summary, lists, privacy filter (~7,900 lines)
  • src/App.vue — main frontend entry, auth, welcome page (~4,000 lines)
  • src/components/Lists.vue — deterministic lists, meds verification (~3,400 lines)
  • server/routes/files.js — file upload, PDF parsing (~3,100 lines)
  • server/routes/groups.js — group registry, membership, messaging (~3,100 lines)
  • server/routes/auth.js — passkey auth, agent provisioning (~1,600 lines)
  • server/routes/chat.js — chat providers, deep link resolution (~750 lines)

Environment Variables

The goal is to minimize secrets. Several values are derived from the DO token at startup so they don't need separate env vars.

Production (DO App Platform) — required env vars

Variable Purpose
DIGITALOCEAN_TOKEN Master secret. Used for DO API calls, to derive CouchDB password, session secret, admin passphrase, create DO Inference Model Access Key, and auto-discover/create the OpenSearch cluster.
SPACES_AWS_ACCESS_KEY_ID S3-compatible access key for DO Spaces (cannot be derived from DO token — Spaces uses the separate S3 API).
SPACES_AWS_SECRET_ACCESS_KEY S3-compatible secret key for DO Spaces.
PUBLIC_APP_URL The public URL of the app (e.g. https://test.agropper.xyz). Controls secure cookies, trust proxy, and passkey origin.

Chat provider keys (ANTHROPIC_API_KEY, CHATGPT_API_KEY, DEEPSEEK_API_KEY) are not needed in production. All three providers are routed through DO Serverless Inference automatically. GEMINI_API_KEY is optional (Gemini is not available on DO Inference).

Derived from DO token (no env var needed)

Value Derivation
CouchDB password HMAC-SHA256(token, 'maia-couchdb-admin') base64url, first 32 chars
Session secret HMAC-SHA256(token, 'maia-session-secret') base64url, first 32 chars
Admin passphrase DO token used directly (pasted once at first admin login, then passkey takes over)
Admin username Hard-coded to admin
CouchDB username Hard-coded to admin
DO Inference key Created via DO API, cached in CouchDB maia_config/do_inference_key
OpenSearch database ID Discovered via DO API (GET /v2/databases?engine=opensearch), or created if none exists. Cached in CouchDB maia_config/opensearch_database_id. One cluster per account enforced.
Port Defaults to 3001; DO App Platform sets PORT automatically

Local development — .env file

Variable Typical value Purpose
PUBLIC_APP_URL http://localhost:5173 Local Vite dev server
CLOUDANT_URL http://localhost:5984 Local Docker CouchDB
DIGITALOCEAN_TOKEN dop_v1_... Required for DO API calls
SPACES_AWS_ACCESS_KEY_ID DO00... Same as production
SPACES_AWS_SECRET_ACCESS_KEY f1Ru... Same as production

DO token rotation warning

If the DO token is rotated, the derived CouchDB password changes but the CouchDB droplet still has the old one. Update the CouchDB admin password via PUT /_node/_local/_config/admins/admin or SSH to the droplet. Delete maia_config/do_inference_key and maia_config/opensearch_database_id in CouchDB so they are re-created on next startup. Session secret rotation logs out all users (they re-authenticate with passkeys).

Testing

  • No automated test suite currently; test manually via the running app
  • Build check: npx vite build
