Add a new Quickstart starter template that lets users pick programming
languages, editors, and an optional Git repo to clone. The template uses
Docker under the hood but presents a developer-focused experience: pick
your tools, start coding.
## What's included
- **Languages parameter** (multi-select): Python, Node.js, Go, Rust,
Java, C/C++
- **IDEs parameter** (multi-select): VS Code (Browser), VS Code Desktop,
Cursor, JetBrains, Zed, Windsurf
- **Git repo parameter**: Optional URL to clone on workspace start
- **JetBrains filtering**: Maps selected languages to relevant IDE codes
(Python → PyCharm, Go → GoLand, etc.)
- **Docker precondition check**: Uses `data "external"` +
`terraform_data` precondition to surface a friendly error when Docker is
unavailable, before the Docker provider fails with a cryptic message
- **4 presets**: Web Development, Backend (Go), Data Science, Full Stack
- **Single install script**: All languages install in one `coder_script`
to avoid apt-get lock conflicts (agent scripts run in parallel via
`errgroup`)
<details><summary>Design decisions</summary>
- **Docker as invisible backend**: Docker is required on the Coder
server but never mentioned in the user-facing parameter UI. The
experience is entirely "pick languages, pick editors, start coding."
- **`coder_script` over startup_script**: Language installs use a
templated script file (`install-languages.sh.tftpl`) driven by the
languages parameter. A single script avoids dpkg lock contention since
`coder_script` resources execute concurrently.
- **`data "external"` for Docker check**: The external provider probes
Docker availability independently of the Docker provider. If Docker is
down, the `terraform_data` precondition fails with a human-readable
message before any `docker_*` resource is evaluated. This depends on the
Docker provider connecting lazily (at resource eval time, not at
provider init), which current behavior confirms.
- **JetBrains filtering by language**: Rather than showing all 9
JetBrains IDEs, the template computes relevant IDE codes from the
language selection (e.g. Python → PY, Go → GO) and passes them as
`default` to the JetBrains module.
- **Arch-aware Go install**: The install script detects `uname -m` to
download the correct Go binary for amd64 or arm64.

Improves the Docker daemon troubleshooting in the quickstart and Docker
install docs:
- Renames the quickstart entry from "Cannot connect to the Docker daemon
on Linux" to cover all platforms.
- Adds a plain-English explanation of what the error means (Docker is
not installed or not running).
- Adds tabbed macOS/Linux/Windows instructions to the quickstart (macOS
and Windows were missing).
- Simplifies the Linux steps to match what Step 1 of the quickstart
already teaches.
- Adds a matching entry to `docs/install/docker.md` with a cross-link to
the quickstart for platform-specific steps.
Supersedes #24907 which was closed without merging.
Fixes https://linear.app/codercom/issue/DEVREL-23
> Generated with [Coder Agents](https://coder.com/agents)
Walking through the quickstart as a new user surfaced several small
friction points and formatting issues. This PR fixes the ones I hit:
- Split the combined Linux/macOS install tab — the steps are
meaningfully different (daemon vs Docker Desktop, package vs `.app`),
and collapsing them forced readers to mentally filter instructions.
- Added a "Launch the Docker daemon" step for Linux and "Open Docker
Desktop" for macOS/Windows. Without this, a new user who installs Docker
and proceeds to `coder server` hits the "Cannot connect to the Docker
daemon" error on first workspace build.
- Added "Familiarity with running commands in the terminal" to
Prerequisites to set expectations accurately.
- Fixed "Setup" → "Set Up" (verb form) in the Step 1 heading.
- Fixed "Congratulation" → "Congratulations".
- Corrected ```hcl` code fences to ```shell` on `git clone`, `cd`, and
`coder template push` commands — none of those are HCL.
- Added trailing punctuation to numbered-list items in the Tasks section
for consistency.
- Stripped Google Analytics session parameters (`_gl`, `_ga`, `_gcl_au`)
from two `registry.coder.com` URLs. These were copy-pasted from a
browser session and leak a GA session ID into public docs.
- Scoped the "Cannot connect to the Docker daemon" troubleshooting
heading to Linux, since it's specific to the Linux install path.
- Minor copyediting for tone and clarity in the intro and overview.

Adds TIP alerts to the quickstart guide and the template contribution
guide linking to the
[coder-templates](https://github.com/coder/registry/blob/main/.agents/skills/coder-templates/SKILL.md)
agent skill from the Coder Registry. This gives contributors and new
users a pointer to AI-assisted template authoring when they first
encounter template creation.
This removes the deprecated AITaskPromptParameterName constant and all
backward compatibility code that was added for v2.28.
- Remove AITaskPromptParameterName constant from codersdk/aitasks.go
- Remove backward compatibility code in coderd/aitasks.go that populated
the "AI Prompt" parameter for templates that defined it
- Remove the backward compatibility test (OK AIPromptBackCompat)
- Update dbfake to no longer set the AI Prompt parameter
- Remove AITaskPromptParameterName from frontend TypeScript types
- Remove preset prompt read-only feature from TaskPrompt component
- Update docs to reflect that pre-2.28 definition is no longer supported
Task prompts are now exclusively stored in the tasks.prompt database
column, as introduced in the migration that added the tasks table.
fix a grammar issue.
Added an extra whitespace to the end / expanded the width of the table
to maintain space as adding the one char would have pushed `helps` hard
up against the table edge.

## Changes
1. Update the `0.0.0.0:3001` web UI address to `localhost:3000`. Coder
starts on port 3000 by default. It'd use 3001 only if 3000 was already
taken.
2. Update the screenshot of the `/setup` page to reflect how it will
look like after merging https://github.com/coder/coder/pull/16662. Note:
this PR should be merged only after the other one is.
3. Minor phrasing changes.
