Problem

A user on Windows (Norwegian locale) got:

error: Failed to install plugin for GitHub Copilot. copilot plugin install failed (exit 1)

Running the manual command showed Failed to install plugin: Ingen tilgang. (os error 5) — Access is denied. The plugin was already installed and working: the running Copilot app holds the files in ~/.copilot/installed-plugins/archgate open, so copilot plugin install cannot replace them.

Fix

  • installCopilotPlugin() checks copilot plugin list when the install fails. If archgate@archgate is listed it returns a new mode: "existing" instead of throwing; otherwise it still throws.
  • archgate plugin install prints "Archgate plugin already installed for GitHub Copilot." plus a hint to close the app and run copilot plugin update archgate@archgate.
  • archgate init treats existing as a completed install.
  • CLAUDE.md documents the new mode.

Tests

  • existing mode when install fails and list shows the plugin
  • still throws UserError when install fails and the plugin is absent
  • command output for existing, and initProject result for existing

bun run validate passes. The locked-file condition itself was not reproduced locally (Copilot app not running); behaviour is covered with mocked subprocess output.

📝 Walkthrough

When a Copilot CLI installation fails, the installer checks successful copilot plugin list --json output for archgate@archgate. If the plugin exists, the installer returns mode: "existing" instead of the install error. The plugin command reports the existing installation and provides a refresh command. Project initialization treats this mode as automatically installed. Tests cover detection, caller behavior, and unchanged error handling.

Priority: ⬇️ Low

Merge Risk: 🟡 Moderate · up to ac4a0

A failed reinstall can still report failure despite an existing Archgate plugin, or report completion when that plugin is disabled. Fix these detection cases before merging.

Pre-merge checks: Passed 5
Check name Status Explanation
Title check Passed The title clearly and concisely describes preserving an existing Copilot plugin installation when reinstallation is blocked.

## Adding a New Editor Target

**GitHub Copilot has the same two-distribution shape — and a declarative install path.** The Copilot desktop app ships no CLI binary but shares `copilotConfigDir()` (`~/.copilot/`) with the `copilot` CLI, so copilot-gated behavior must use `isCopilotAvailable()` (PATH check OR config dir exists), never `isCopilotCliAvailable()` alone. The plugin install is declarative-first: `installCopilotPlugin()` always writes the marketplace + plugin declaration into `~/.copilot/settings.json` (`extraKnownMarketplaces` + `enabledPlugins` — Copilot's marketplace registry and auto-install list, read by both distributions on startup; an existing `archgate` entry is overwritten to correct stale URLs), then additionally runs `copilot plugin install archgatearchgate` when the CLI is on PATH. `mode: "declarative"` in the result means the user must restart the Copilot app for the install to take effect. `mode: "existing"` means the CLI install fai...

Timestamp: 2026-07-25T22:03:14.216Z
Learning: In Archgate boundary-wrapped CLI command actions (the handlers that rely on `handleCommandError()` for user-facing error output), expected-failure guards should signal user errors by throwing `new UserError(<message/details>)` rather than directly calling `logError()` followed by `exitWith(1)`. This keeps user-facing logging and the exit path centralized in `handleCommandError()`. For normal/computed command outcomes (e.g., `const exitCode = getExitCode(await runChecks(...))`), use `await exitWith(exitCode)` instead of calling `process.exit(exitCode)` so telemetry/Sentry flushing and outcome tagging still run.

- Around line 480-481: Update the plugin matching logic in the installer flow
around parsed.data.some so it only returns mode "existing" when the matching
archgate@archgate row has enabled set to true; treat a disabled match as not
installed and preserve the installation path. Add installer test coverage for
the disabled-plugin case.
- Line 464: Update the plugin-list row schema near the object containing name
and marketplace so marketplace is optional, then enforce its presence only when
identifying the Archgate plugin match; allow unrelated direct-install plugins
without marketplace to remain valid.

## Adding a New Editor Target

**GitHub Copilot has the same two-distribution shape — and a declarative install path.** The Copilot desktop app ships no CLI binary but shares `copilotConfigDir()` (`~/.copilot/`) with the `copilot` CLI, so copilot-gated behavior must use `isCopilotAvailable()` (PATH check OR config dir exists), never `isCopilotCliAvailable()` alone. The plugin install is declarative-first: `installCopilotPlugin()` always writes the marketplace + plugin declaration into `~/.copilot/settings.json` (`extraKnownMarketplaces` + `enabledPlugins` — Copilot's marketplace registry and auto-install list, read by both distributions on startup; an existing `archgate` entry is overwritten to correct stale URLs), then additionally runs `copilot plugin install archgatearchgate` when the CLI is on PATH. `mode: "declarative"` in the result means the user must restart the Copilot app for the install to take effect. `mode: "existing"` means the CLI install fai...

…ocked

On Windows the running GitHub Copilot app holds the installed plugin's
files open, so `copilot plugin install` over an existing install fails
with os error 5 (access denied) and `archgate plugin install` reported a
hard failure. When the install fails, check `copilot plugin list`; if
archgate@archgate is already installed, report it as installed with a
hint to run `copilot plugin update` after closing the app.

This PR was generated with
[simple-release](https://github.com/TrigenSoftware/simple-release).

<details>
<summary>📄 Cheatsheet</summary>
<br>



You can configure the bot's behavior through a pull request comment
using the `!simple-release/set-options` command.

### Command Format

````md
!simple-release/set-options

```json
{
  "bump": {}
}
```
````

### Useful Parameters

The options shape the pull request generation, so the `bump` ones matter
here. Release-time options like `publish` belong in the config file.

| Parameter | Type | Description |
|-----------|------|-------------|
| `version` | `string` | Force set specific version |
| `as` | `'major' \| 'minor' \| 'patch' \| 'prerelease'` | Release type.
`prerelease` keeps the type derived from the commits and makes the
version a prerelease |
| `prerelease` | `string` | Pre-release identifier (e.g., "alpha",
"beta") |
| `firstRelease` | `boolean` | Whether this is the first release |
| `skip` | `boolean` | Skip version bump |
| `byProject` | `Record<string, object>` | Per-project bump options for
monorepos |

### Usage Examples

#### Force specific version

````md
!simple-release/set-options

```json
{
  "bump": {
    "version": "2.0.0"
  }
}
```
````

#### Force major bump

````md
!simple-release/set-options

```json
{
  "bump": {
    "as": "major"
  }
}
```
````

#### Create alpha pre-release

````md
!simple-release/set-options

```json
{
  "bump": {
    "prerelease": "alpha"
  }
}
```
````

### Custom Changelog Preamble

You can add custom markdown to the top of the changelog (right after the
version header) using the `!simple-release/set-preamble` command. The
markdown after the command line becomes the preamble. Start its headings
at `###` — the level of the generated changelog sections like `###
Features`.

```md
!simple-release/set-preamble

### What's new?

- The website was completely redesigned
- The new API gives you awesome possibilities
```

In a monorepo, pass the full package name after the command to target a
single package's changelog. Wrap the name in backticks so GitHub keeps
it as text instead of a mention:

```md
!simple-release/set-preamble `@your-org/core`

### Core changes

- New plugin system
```

Use one comment per package, plus one without a name for the whole
release.

### Access Restrictions

The commands can only be used by users with permissions:
- repository owner
- organization member
- collaborator

### Notes

- The last comment with `!simple-release/set-options` command takes
priority
- The last `!simple-release/set-preamble` comment per package takes
priority
- JSON must be valid, otherwise the `set-options` command will be
ignored
- Parameters apply only to the current release execution
- The commands can be updated by editing the comment or adding a new one
