+# Onyx Dev Container
+
+A containerized development environment for working on Onyx.
+
+## What's included
+
+- Ubuntu 26.04 base image
+- Node.js 20, uv, Claude Code
+- GitHub CLI (`gh`)
+- Neovim, ripgrep, fd, fzf, jq, make, wget, unzip
+- Zsh as default shell (sources host `~/.zshrc` if available)
+- Python venv auto-activation
+- Network firewall (default-deny, whitelists npm, GitHub, Anthropic APIs, Sentry, and VS Code update servers)
+
+## Usage
+
+### CLI (`ods dev`)
+
+The [`ods` devtools CLI](../tools/ods/README.md) provides workspace-aware wrappers
+for all devcontainer operations (also available as `ods dc`):
+
+```bash
+# Start the container
+ods dev up
+
+# Open a shell
+ods dev into
+
+# Run a command
+ods dev exec npm test
+
+# Stop the container
+ods dev stop
+```
+
+## Restarting the container
+
+```bash
+# Restart the container
+ods dev restart
+
+# Pull the latest published image and recreate
+ods dev rebuild
+```
+
+## Image
+
+The devcontainer uses a prebuilt image published to `onyxdotapp/onyx-devcontainer`.
+The tag is pinned in `devcontainer.json` — no local build is required.
+
+To build the image locally (e.g. while iterating on the Dockerfile):
+
+```bash
+docker buildx bake devcontainer
+```
+
+The `devcontainer` target is defined in `docker-bake.hcl` at the repo root.
+
+## User & permissions
+
+The container runs as the `dev` user by default (`remoteUser` in devcontainer.json).
+An init script (`init-dev-user.sh`) runs at container start to ensure the active
+user has read/write access to the bind-mounted workspace:
+
+- **Standard Docker** — `dev`'s UID/GID is remapped to match the workspace owner,
+  so file permissions work seamlessly.
+- **Rootless Docker** — The workspace appears as root-owned (UID 0) inside the
+  container due to user-namespace mapping. `ods dev up` auto-detects rootless Docker
+  and sets `DEVCONTAINER_REMOTE_USER=root` so the container runs as root — which
+  maps back to your host user via the user namespace. New files are owned by your
+  host UID and no ACL workarounds are needed.
+
+  To override the auto-detection, set `DEVCONTAINER_REMOTE_USER` before running
+  `ods dev up`.
+
+## Firewall
+
+The container starts with a default-deny firewall (`init-firewall.sh`) that only allows outbound traffic to:
+
+- npm registry
+- GitHub
+- Anthropic API
+- Sentry
+- VS Code update servers
+
+This requires the `NET_ADMIN` and `NET_RAW` capabilities, which are added via `runArgs` in `devcontainer.json`.

 If we approve an issue, we are promising you the following:
+
 - Your work will receive timely attention and we will put aside other important items to ensure you are not blocked.
 - You will receive necessary coaching on eng quality, system design, etc. to ensure the feature is completed well.
 - The Onyx team will pull resources and bandwidth from design, PM, and engineering to ensure that you have all the resources to build the feature to the quality required for merging.
 
 Because this is a large investment from our team, we ask that you:

 - Thoroughly read all the requirements of the design docs, engineering best practices, and try to minimize overhead for the Onyx team.
 - Complete the feature in a timely manner to reduce context switching and an ongoing resource pull from the Onyx team.

 ### Repository Conventions
 
 #### Where code lives
+
 - Pydantic + data models: `models.py` files.
 - DB interface functions (excluding lazy loading): `db/` directory.
 - LLM prompts: `prompts/` directory, roughly mirroring the code layout that uses them.
 - API routes: `server/` directory.
 
 #### Pydantic and modeling
+
 - Prefer **Pydantic** over dataclasses.
 - If absolutely required, use `allow_arbitrary_types`.
 
 #### Data conventions
+
 - Prefer explicit `None` over sentinel empty strings (usually; depends on intent).
 - Prefer explicit identifiers: use string enums instead of integer codes.
 - Avoid magic numbers (co-location is good when necessary). **Always avoid magic strings.**
 
 #### Logging
+
 - Log messages where they are created.
 - Don't propagate log messages around just to log them elsewhere.
 
 #### Encapsulation
+
 - Don't use private attributes/methods/properties from other classes/modules.
 - "Private" is private — respect that boundary.
 
 #### SQLAlchemy guidance
+
 - Lazy loading is often bad at scale, especially across multiple list relationships.
 - Be careful when accessing SQLAlchemy object attributes:
   - It can help avoid redundant DB queries,

 - **Test both flag states.** Ensure the codebase works correctly with the flag on and off.
 
 #### Miscellaneous
+
 - Any TODOs you add in the code must be accompanied by either the name/username of the owner of that TODO, or an issue number for an issue referencing that piece of work.
 - Avoid module-level logic that runs on import, which leads to import-time side effects. Essentially every piece of meaningful logic should exist within some function that has to be explicitly invoked. Acceptable exceptions may include loading environment variables or setting up loggers.
   - If you find yourself needing something like this, you may want that logic to exist in a file dedicated for manual execution (contains `if __name__ == "__main__":`) which should not be imported by anything else.
