+# oAI-Web - Personal AI Agent
+
+A secure, self-hosted personal AI agent powered by Claude. Handles calendar, email, files, web research, and Telegram - controlled by you, running on your own hardware.
+
+## Features
+
+- **Chat interface** - conversational UI via browser, with model selector
+- **CalDAV** - read and write calendar events
+- **Email** - read inbox, send replies (whitelist-managed recipients)
+- **Filesystem** - read/write files in declared sandbox directories
+- **Web access** - tiered: whitelisted domains always allowed, others on request
+- **Push notifications** - Pushover for iOS/Android
+- **Telegram** - send and receive messages via your own bot
+- **Scheduled tasks** - cron-based autonomous tasks with declared permission scopes
+- **Agents** - goal-oriented runs with model selection and full run history
+- **Audit log** - every tool call logged, append-only
+- **Multi-user** - each user has their own credentials and settings
+
+---
+
+## Requirements
+
+- Docker and Docker Compose
+- An API key from [Anthropic](https://console.anthropic.com) and/or [OpenRouter](https://openrouter.ai)
+- A PostgreSQL-compatible host (included in the compose file)
+
+---
+
+## Installation
+
+### 1. Get the files
+
+Download or copy these files into a directory on your server:
+
+- `docker-compose.example.yml` - rename to `docker-compose.yml`
+- `.env.example` - rename to `.env`
+- `SOUL.md.example` - rename to `SOUL.md`
+- `USER.md.example` - rename to `USER.md`
+
+```bash
+cp docker-compose.example.yml docker-compose.yml
+cp .env.example .env
+cp SOUL.md.example SOUL.md
+cp USER.md.example USER.md
+```
+
+### 2. Create the data directory
+
+```bash
+mkdir -p data
+```
+
+### 3. Configure the environment
+
+Edit `.env` - see the [Environment Variables](#environment-variables) section below.
+
+### 4. Pull and start
+
+```bash
+docker compose pull
+docker compose up -d
+```
+
+Open `http://<your-server-ip>:8080` in your browser.
+
+On first run you will be taken through a short setup wizard to create your admin account.
+
+---
+
+## Environment Variables
+
+Open `.env` and fill in the values. Required fields are marked with `*`.
+
+### AI Provider
+
+```env
+# Which provider to use as default: anthropic | openrouter | openai
+DEFAULT_PROVIDER=anthropic
+
+# Override the default model (leave empty to use the provider's default)
+# DEFAULT_MODEL=claude-sonnet-4-6
+
+# Model pre-selected in the chat UI (leave empty to use provider default)
+# DEFAULT_CHAT_MODEL=claude-sonnet-4-6
+```
+
+Your actual API keys are **not** set here - they are entered via the web UI under **Settings - Credentials** and stored encrypted in the database.
+
+---
+
+### Security *
+
+```env
+# Master password for the encrypted credential store.
+# All your API keys, passwords, and secrets are encrypted with this.
+# Choose a strong passphrase and keep it safe - if lost, credentials cannot be recovered.
+DB_MASTER_PASSWORD=change-me-to-a-strong-passphrase
+```
+
+---
+
+### Server
+
+```env
+# Port the web interface listens on (default: 8080)
+PORT=8080
+
+# Timezone for display - dates are stored internally as UTC
+TIMEZONE=Europe/Oslo
+```
+
+---
+
+### Agent Limits
+
+```env
+# Maximum number of tool calls per agent run
+MAX_TOOL_CALLS=20
+
+# Maximum number of autonomous (scheduled/agent) runs per hour
+MAX_AUTONOMOUS_RUNS_PER_HOUR=10
+```
+
+Both values can also be changed live from **Settings - General** without restarting.
+
+---
+
+### Database *
+
+```env
+# Main application database
+AIDE_DB_URL=postgresql://aide:change-me@postgres:5432/aide
+
+# 2nd Brain database password (pgvector)
+BRAIN_DB_PASSWORD=change-me-to-a-strong-passphrase
+
+# Brain connection string - defaults to the bundled postgres service
+BRAIN_DB_URL=postgresql://brain:${BRAIN_DB_PASSWORD}@postgres:5432/brain
+
+# Access key for the Brain MCP endpoint (generate with: openssl rand -hex 32)
+BRAIN_MCP_KEY=
+```
+
+Change the `change-me` passwords in `AIDE_DB_URL` and `BRAIN_DB_PASSWORD` to something strong. They must match - if you change `BRAIN_DB_PASSWORD`, the same value is substituted into `BRAIN_DB_URL` automatically.
+
+---
+
+## Personalising the Agent
+
+### SOUL.md - Agent identity and personality
+
+`SOUL.md` defines who your agent is. The name is extracted automatically from the first line matching `You are **Name**`.
+
+Key sections to edit:
+
+**Name** - change `Jarvis` to whatever you want your agent to be called:
+```markdown
+You are **Jarvis**, a personal AI assistant...
+```
+
+**Character** - describe how you want the agent to behave. Be specific. Examples:
+- "You are concise and avoid unnecessary commentary."
+- "You are proactive - if you notice something relevant while completing a task, mention it briefly."
+- "You never use bullet points unless explicitly asked."
+
+**Values** - define what the agent should prioritise:
+- Privacy, minimal footprint, and transparency are good defaults.
+- Add domain-specific values if relevant (e.g. "always prefer open-source tools when suggesting options").
+
+**Language** - specify language behaviour explicitly:
+- "Always respond in the same language the user wrote in."
+- "Default to Norwegian unless the message is in another language."
+
+**Communication style** - tune the tone:
+- Formal vs. casual, verbose vs. terse, proactive vs. reactive.
+- You can ban specific phrases: "Never start a response with 'Certainly!' or 'Of course!'."
+
+The file is mounted read-only into the container. Changes take effect on the next `docker compose restart`.
+
+---
+
+### USER.md - Context about you
+
+`USER.md` gives the agent background knowledge about you. It is injected into every system prompt, so keep it factual and relevant - not a biography.
+
+**Identity** - name, location, timezone. These help the agent interpret time references and address you correctly.
+
+```markdown
+## Identity
+
+- **Name**: Jane
+- **Location**: Oslo, Norway
+- **Timezone**: Europe/Oslo
+```
+
+**Language preferences** - if you want to override SOUL.md language rules for your specific case:
+
+```markdown
+## Language
+
+- Respond in the exact language the user's message is written in.
+- Do not assume Norwegian because of my location.
+```
+
+**Professional context** - role and responsibilities the agent should be aware of:
+
+```markdown
+## Context and background
+
+- Works as a software architect
+- Primarily works with Python and Kubernetes
+- Manages a small team of three developers
+```
+
+**People** - names and relationships. Helps the agent interpret messages like "send this to my manager":
+
+```markdown
+## People
+
+- [Alice Smith] - Manager
+- [Bob Jones] - Colleague, backend team
+- [Sara Lee] - Partner
+```
+
+**Recurring tasks and routines** - anything time-sensitive the agent should know about:
+
+```markdown
+## Recurring tasks and routines
+
+- Weekly team standup every Monday at 09:00
+- Monthly report due on the last Friday of each month
+```
+
+**Hobbies and interests** - optional, but helps the agent contextualise requests:
+
+```markdown
+## Hobbies and Interests
+
+- Photography
+- Self-hosting and home lab
+- Cycling in summer
+```
+
+The file is mounted read-only into the container. Changes take effect on the next `docker compose restart`.
+
+---
+
+## First Run - Settings
+
+After the setup wizard, go to **Settings** to configure your services.
+
+### Credentials (admin only)
+
+Add credentials for the services you use. Common keys:
+
+| Key | Example | Used by |
+|-----|---------|---------|
+| `anthropic_api_key` | `sk-ant-...` | Claude (Anthropic) |
+| `openrouter_api_key` | `sk-or-...` | OpenRouter models |
+| `mailcow_host` | `mail.yourdomain.com` | CalDAV, Email |
+| `mailcow_username` | `you@yourdomain.com` | CalDAV, Email |
+| `mailcow_password` | your IMAP password | CalDAV, Email |
+| `caldav_calendar_name` | `personal` | CalDAV |
+| `pushover_app_token` | from Pushover dashboard | Push notifications |
+| `telegram_bot_token` | from @BotFather | Telegram |
+
+### Whitelists
+
+- **Email whitelist** - addresses the agent is allowed to send email to
+- **Web whitelist** - domains always accessible to the agent (Tier 1)
+- **Filesystem sandbox** - directories the agent is allowed to read/write
+
+---
+
+## Updating
+
+```bash
+docker compose pull
+docker compose up -d
+```
+
+---
+
+## Pages
+
+| URL | Description |
+|-----|-------------|
+| `/` | Chat - send messages, select model, view tool activity |
+| `/tasks` | Scheduled tasks - cron-based autonomous tasks |
+| `/agents` | Agents - goal-oriented runs with model selection and run history |
+| `/audit` | Audit log - filterable view of every tool call |
+| `/settings` | Credentials, whitelists, agent config, Telegram, and more |

+# oAI-Web — Soul
+
+You are **Jarvis**, a personal AI assistant built for one person: your owner. You run on their own hardware, have access to their calendar, email, and files, and act as a trusted extension of their intentions.
+
+## Character
+
+- You are direct, thoughtful, and capable. You don't pad responses with unnecessary pleasantries.
+- You are curious and engaged — you take tasks seriously and think them through before acting.
+- You have a dry, understated sense of humor when the situation calls for it, but you keep it brief.
+- You are honest about uncertainty. When you don't know something, you say so rather than guessing.
+
+## Values
+
+- **Privacy first** — you handle personal information with care and discretion. You never reference sensitive data beyond what the current task requires.
+- **Minimal footprint** — prefer doing less and confirming rather than taking broad or irreversible actions.
+- **Transparency** — explain what you're doing and why, especially when using tools or making decisions on the user's behalf.
+- **Reliability** — do what you say you'll do. If something goes wrong, say so clearly and suggest what to do next.
+
+## Language
+
+- Always respond in the same language the user wrote their message in. If they write in English, respond in English. Never switch languages unless the user does first.
+
+## Communication style
+
+- Default to concise. A short, accurate answer is almost always better than a long one.
+- Use bullet points for lists and steps; prose for explanations and context.
+- Match the user's register — casual when they're casual, precise when they need precision.
+- Never open with filler phrases like "Certainly!", "Of course!", "Absolutely!", or "Great question!".
+- When you're unsure what the user wants, ask one focused question rather than listing all possibilities.
+- If a command or request is clear and unambiguous, complete it without further questions.

+# USER.md — About the owner

+## Identity

+- **Name**: Jane
+- **Location**: Oslo, Norway
+- **Timezone**: Europe/Oslo
+
+## Language
+
+- Respond in the exact language the user's message is written in. Do not default to a language based on location.
+
+## Communication preferences
+
+- Prefer short, direct answers unless asked for detail or explanation.
+- When summarizing emails or calendar events, highlight what requires action.
+
+## Context and background
+
+- Describe the user's role or profession here.
+- Add any relevant professional context that helps the assistant prioritize tasks.
+
+## People
+
+- [Name] — Relationship (e.g. partner, colleague)
+- [Name] — Relationship
+
+## Recurring tasks and routines
+
+- Add any regular tasks or schedules the assistant should be aware of.
+
+## Hobbies and Interests
+
+- Add interests that help the assistant understand priorities and context.
