# Profiles-for-Coder

Coder templates for per-discipline dev environments (Default, 3D Printing,
COBOL, Python, TTRPG, Web). Each environment is its own Coder **template** -
not a dropdown inside one shared container, which is what this repo used to
do and which didn't actually work.

## Layout

```
templates/
  default/main.tf        # Standard Default Dev
  3d-printing/main.tf     # 3D Printing & Engineering
  cobol/main.tf           # COBOL Modern Mainframe
  python/main.tf          # Python Engineering
  ttrpg/main.tf            # TTRPG & Lore Building
  web/main.tf              # Web Applications
scripts/
  cli-setup-wizard.sh      # shared first-run wizard, see below
  install-skills.sh         # shared Agent Skills installer, see below
profile-templates/         # VS Code .code-profile exports, one per env
extensions/                 # Agent Skills bundles, installed per env (see below)
```

Each `templates/<env>/main.tf` is a complete, independent Coder template
(agent, docker container, code-server, JetBrains). They're deliberately not
built from a shared Terraform module - only their `locals` block differs
(which profile file to read). Push them individually:

```sh
coder templates push profiles-default    -d templates/default
coder templates push profiles-3d         -d templates/3d-printing
coder templates push profiles-cobol      -d templates/cobol
coder templates push profiles-python     -d templates/python
coder templates push profiles-ttrpg      -d templates/ttrpg
coder templates push profiles-web        -d templates/web
```

### How the VS Code profile gets applied

`profile-templates/*.code-profile` is a real VS Code Profile export: a JSON
file whose `settings` and `extensions` fields are themselves JSON-encoded
strings (double/triple-nested). Each template's `main.tf` reads and decodes
its matching file **at `terraform apply`/push time** (via `file()` +
`jsondecode()`), then:

- passes the extension ID list straight into the `code-server` module's
  `extensions` input, so code-server installs them on first boot - no
  interactive prompt needed, Terraform handles it declaratively;
- writes the raw `settings.json` text (comments and all - VS Code tolerates
  JSONC) to `~/.local/share/code-server/User/settings.json` via a
  `coder_script`.

This replaces the old approach, which downloaded a zip of this repo from
Gitea *inside* the running container and tried to apply settings from
`~/.local/share/profiles-cache/<profile>.json` - a path that never matched
the actual `.code-profile` file extension, so settings never applied. That
bug (plus the single shared container) is why "one container, many envs"
never really worked.

### Bun

Every template installs [Bun](https://bun.sh) via a `coder_script`
(`curl -fsSL https://bun.sh/install | bash`) and hooks `~/.bun/bin` onto
`PATH` in `~/.bashrc` (the installer doesn't reliably do this itself in a
non-interactive/scripted shell). The CLI setup wizard below uses
`bun install -g <pkg>` instead of `npm install -g <pkg>` for everything it
installs.

### CLI setup wizard

`scripts/cli-setup-wizard.sh` is dropped onto every workspace and hooked
into `~/.bashrc`. It runs in every new interactive terminal - until the user
finishes it - and offers to install + log into:

- **GitHub Copilot CLI** (`bun install -g @github/copilot`, then `copilot login`)
- **Google Antigravity CLI** (`curl -fsSL https://antigravity.google/cli/install.sh | bash`, binary `agy`)
- **Claude Code CLI** (`bun install -g @anthropic-ai/claude-code`, then `claude`)

It does **not** ask about VS Code extensions, since those are handled by
Terraform (see above). Once the user confirms completion it writes a
sentinel file (`~/.cache/coder-cli-wizard/done`) and stops prompting. It can
always be re-run manually: `bash /opt/coder/cli-setup-wizard.sh --force`.

### `extensions/` directory -> Agent Skills

`extensions/awesome-skills-plugin` and `extensions/custom-specialty-plugin`
are **Agent Skills bundles** (`plugin.json` + `SKILL.md` files) - the old
root `main.tf` copied this folder straight into code-server's VS Code
extensions directory, which never worked since these aren't VS Code
extension packages.

Each template now runs `scripts/install-skills.sh` (via a `coder_script`,
pulling a fresh zip of this repo from Gitea rather than embedding ~2.5MB
into Terraform state) to install skills into all three AI CLIs' personal
skills directories:

| CLI | Skills directory |
| --- | --- |
| Claude Code | `~/.claude/skills/<name>/` |
| GitHub Copilot CLI | `~/.copilot/skills/<name>/` |
| Antigravity CLI | `~/.gemini/config/skills/<name>/` (per antigravity.google/docs/skills - some third-party docs disagree on this path, worth a spot-check on a live workspace) |

Every environment gets the full `extensions/awesome-skills-plugin/skills/*`
bundle. On top of that, whichever env has a matching entry in
`extensions/custom-specialty-plugin/skills/` gets it installed too, set via
the `SPECIALTY_SKILLS` env var passed to the script from each template's
`install_skills` `coder_script`:

- COBOL -> `cobol-teacher`
- 3D Printing -> `openscad-parametric`
- TTRPG -> `foundryvtt-modding` and `ttrpg-lore-weaver`
- Default / Python / Web -> none (no matching specialty skill exists yet)
