# Email Agent

Triage the family inbox from one page: all mail lands in a single Gmail account
and this service classifies it, recommends actions, performs bulk actions, drafts
replies, and answers the Hub.

The build spec is [`AGENTS.md`](AGENTS.md). `ORIGINAL_NOTES.md` is archived
pre-planning material and is not authoritative.

## Status

**Phase 1.1 — Go service skeleton.** Complete when this file was written:
config from the environment, SQLite schema init, `GET /health`, Dockerfile and
docker-compose. Mail fetch, classification, login, and the HTMX screens come in
later phases.

## Layout

```
cmd/email-agent/        service entry point
internal/config/        environment-driven configuration
internal/store/         SQLite open + schema (internal/store/schema.sql)
internal/server/        HTTP routes and middleware
internal/version/       build metadata (set via -ldflags)
Dockerfile              multi-stage, CGO-free build
docker-compose.yml      this project's own container and image
```

## Configuration

All configuration is read from environment variables. Secrets live in
`~/.config/environment.d/10-secrets.conf` on the host and are passed into the
container by `docker-compose`; no secret value is ever committed. See
[`.env.example`](.env.example) for the full list of names.

Key variables:

| Variable | Default | Purpose |
|---|---|---|
| `EMAIL_AGENT_ENV` | `development` | `development`, `production`, or `test` |
| `EMAIL_AGENT_ADDR` | `:8790` | Listen address |
| `EMAIL_AGENT_PORT` | `8790` | Listen port (used when `EMAIL_AGENT_ADDR` is unset) |
| `EMAIL_AGENT_DB_PATH` | `data/email_agent.db` | SQLite file |
| `EMAIL_AGENT_LOG_LEVEL` | `info` | `debug`, `info`, `warn`, `error` |
| `EMAIL_AGENT_SESSION_SECRET` | _(empty)_ | Session cookie signing key (Phase 1.2) |

## Run locally

```sh
go run ./cmd/email-agent
curl -s localhost:8790/health
```

## Docker

```sh
docker compose up -d --build
curl -s localhost:8790/health
```

The container is `email-agent`, image `email-agent:latest`, named volume
`email_agent_data` mounted at `/data`, listening on **8790**. It runs as an
unprivileged user and has a built-in healthcheck (`email-agent -healthcheck`).
Caddy on `.35` proxies `mail.lab.audasmedia.com.au` to this port.

## Endpoints (Phase 1)

| Method | Path | Purpose |
|---|---|---|
| `GET` | `/health` | Liveness + database check, JSON |
| `GET` | `/readyz` | Readiness, JSON |
| `GET` | `/` | Placeholder dashboard (real screens in Phase 1.2) |

## Database

SQLite is opened with the pure-Go `modernc.org/sqlite` driver (no CGO). The
schema in `internal/store/schema.sql` creates the AGENTS.md §7 tables:
`messages`, `classifications`, `rules`, `actions_log`, `unsubscribe`, `drafts`,
`summaries`, plus `schema_migrations`. Schema init is idempotent and runs on
every start.
