feat: expose CLI config options in Settings UI (fixes #698) (#806)

github-actions[bot] · copilot-agentic-workflow[bot] · Copilot · web-flow · commit 2edab8de3fe8 · 2026-04-29T17:42:47.000-05:00
## Summary Adds an **Advanced** section to the Settings page with toggles for three Copilot CLI configuration options requested in #698: | Toggle | Description | |--------|-------------| | **Compact Paste** | Collapse large pasted content to save context-window tokens | | **Respect .gitignore** | Exclude gitignored files from working-tree context | | **Disable All Hooks** | Globally disable all CLI hooks (pre-tool-use, post-tool-use, etc.) | ## Changes ### Model (`ConnectionSettings.cs`) - Added `CompactPaste`, `RespectGitignore`, `DisableAllHooks` boolean properties (default `false`) - Added `SyncCliConfig()` method that merges these values into `~/.copilot/config.json`, preserving any existing keys in the file ### Registry (`SettingsRegistry.cs`) - Registered three `SettingDescriptor` entries under a new **Advanced** category - Hidden in Remote/Demo modes (no local CLI to configure) - Searchable by keywords: compact, paste, gitignore, hooks, cli config, advanced ### UI (`Settings.razor`) - Added ⚙️ Advanced nav item in the sidebar - Added Advanced section with description and toggle rendering via `SettingEditor` - Wired `OnSettingChanged` to call `SyncCliConfig()` when any `advanced.*` setting changes - Added `GroupVisible("advanced")` search support ### Tests - **ConnectionSettingsTests**: defaults, JSON round-trip, backward compatibility, `SyncCliConfig` write + merge preservation - **SettingsRegistryTests**: get/set value, visibility in different modes, search by keywords - **AdvancedCliConfigTests** (integration): verifies the Advanced section renders in the live Blazor UI ## Test Results All **3661 unit tests pass**. Integration tests build successfully. - Fixes #698 > [!WARNING] > <details> > <summary><strong>⚠️ Firewall blocked 1 domain</strong></summary> > > The following domain was blocked by the firewall during workflow execution: > > - `192.0.2.1` > > To allow these domains, add them to the `network.allowed` list in your workflow frontmatter: > > ```yaml > network: > allowed: > - defaults > - "192.0.2.1" > ``` > > See [Network Configuration](https://github.github.com/gh-aw/reference/network/) for more information. > > </details> > Generated by [Agent Fix](https://github.com/PureWeen/PolyPilot/actions/runs/25127158142/agentic_workflow) for issue #698 · ● 50.4M · [◷](https://github.com/search?q=repo%3APureWeen%2FPolyPilot+%22gh-aw-workflow-id%3A+agent-fix%22&type=pullrequests)   Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: copilot-agentic-workflow[bot] <224017+copilot-agentic-workflow[bot]@users.noreply.github.com> Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
