## Problem
The CLI does not honor `default` values on template parameters in two
ways:
1. **`--use-parameter-defaults` rejects empty-string defaults.** The
check `parameterValue != ""` means `default = ""` in Terraform falls
through to an interactive prompt. In CI this causes an EOF error.
2. **`--use-parameter-defaults` only exists on `coder create`.** The
`start`, `update`, and `restart` commands never wire it through. SSH
auto-start passes empty `workspaceParameterFlags{}`, so users SSH-ing
into a stopped workspace with new template parameters get stuck in an
interactive prompt they cannot complete.
## Fix
### 1. Fix empty-string default detection and expose flag on all
commands
Replace `parameterValue != ""` with a check based on `!tvp.Required`. A
parameter with `Required==false` always has a valid default in
Terraform, even if that default is `""`. Also respect CLI defaults
provided via `--parameter-default`.
Move `--use-parameter-defaults` from a standalone option on `create`
into the shared `workspaceParameterFlags` struct. This exposes the flag
(and `CODER_WORKSPACE_USE_PARAMETER_DEFAULTS`) on `start`, `update`, and
`restart` via `allOptions()`. Wire it through
`buildWorkspaceStartRequest` so the resolver receives it.
### 2. SSH auto-start always uses defaults
Set `useParameterDefaults: true` on both `startWorkspace` calls in the
SSH auto-start path (initial start and the forbidden/upgrade fallback).
SSH is non-interactive and should never prompt.

### Scoping decisions
- **`--yes` does not imply `--use-parameter-defaults`**: Making `--yes`
auto-accept defaults exposes a validation gap in the dynamic parameter
path (client-side validation happens during prompting, and skipping
prompts bypasses it). This is deferred to a follow-up that also
addresses `codersdk.ValidateWorkspaceBuildParameter` integration in the
resolver. Tracked in PLAT-114.
- **Explicit overrides always win**: `--parameter`,
`--rich-parameter-file`, and `--preset` are resolved in stages 1-5 of
the resolver, before `resolveWithInput` runs. No change needed for
precedence.
- **`!tvp.Required` vs `parameterValue != ""`**: The `Required` field is
set by the Terraform provider based on whether a `default` is present.
This is the canonical signal for "has a default," not the string value
itself.

Create a new external workspace
Usage
coder external-workspaces create [flags] [workspace]
Description
- Create a workspace for another user (if you have permission):
$ coder create <username>/<workspace_name>
Options
-t, --template
| Type | string |
| Environment | $CODER_TEMPLATE_NAME |
Specify a template name.
--template-version
| Type | string |
| Environment | $CODER_TEMPLATE_VERSION |
Specify a template version name.
--preset
| Type | string |
| Environment | $CODER_PRESET_NAME |
Specify the name of a template version preset. Use 'none' to explicitly indicate that no preset should be used.
--start-at
| Type | string |
| Environment | $CODER_WORKSPACE_START_AT |
Specify the workspace autostart schedule. Check coder schedule start --help for the syntax.
--stop-after
| Type | duration |
| Environment | $CODER_WORKSPACE_STOP_AFTER |
Specify a duration after which the workspace should shut down (e.g. 8h).
--automatic-updates
| Type | string |
| Environment | $CODER_WORKSPACE_AUTOMATIC_UPDATES |
| Default | never |
Specify automatic updates setting for the workspace (accepts 'always' or 'never').

Rich parameter value in the format "name=value".
--rich-parameter-file

| Environment | $CODER_RICH_PARAMETER_FILE |
Specify a file path with values for rich parameters defined in the template. The file should be in YAML format, containing key-value pairs for the parameters.
--parameter-default
| Type | string-array |
| Environment | $CODER_RICH_PARAMETER_DEFAULT |
Rich parameter default values in the format "name=value".
--use-parameter-defaults
