Breakdown of growth, maintenance, and fixes effort over time.
Bugs introduced vs. fixed over time.
Reclassifies engineering effort based on bug attribution. Commits that introduced bugs are retrospectively counted as poor investments.
Investment Quality reclassifies engineering effort based on bug attribution data. Commits identified as buggy origins (those that introduced bugs later fixed by someone) have their grow and maintenance time moved into the Wasted Time category. Their waste (fix commits) remains counted as productive. All other commits retain their standard classification: grow is productive, maintenance is maintenance, and waste (fixes) is productive.
The standard model classifies commits as Growth, Maintenance, or Fixes. Investment Quality adds a quality lens: a commit that introduced a bug is retrospectively counted as a poor investment — the engineering time spent on it was wasted because it ultimately required additional fix work. Fix commits (Fixes in the standard model) are reframed as productive, because fixing bugs is valuable work.

| 1e69270d | This commit addresses **failing tests** within the project's **test suite**, ensuring their successful execution. The work primarily involves **maintenance** to restore the reliability of automated checks, which in turn improves the overall **code quality assurance** process. While specific modules are not identified, the fix contributes to a more stable and trustworthy continuous integration pipeline. | Mar 27 | 1 | – |
| 2a71559b | This commit performs a substantial **maintenance refactoring** by overhauling the core session type definitions, renaming `ISessionData` to `ISession` and `IChatData` to `IChat`. This change propagates across the entire **`sessions`** and **`chat`** subsystems, updating numerous UI components, services, and contributions to align with the new types. Functionally, it **removes the `commitWorktreeFiles` method** and its associated task file commit mechanism from the `SessionsConfigurationService`, simplifying the API. Furthermore, the commit refactors run script actions to leverage the new `ISession` type, directly improving the `/generate-run-commands` functionality, and enhances chat-to-session mapping logic for more robust session retrieval. | Mar 27 | 29 | maint |
| 93cc2b1a | This commit introduces a **fix** for the **CI status widget's layout**, specifically addressing rendering issues within the `sessions` and `changes` contributions. It **refactors the layout logic** in `src/vs/sessions/contrib/changes/browser/ciStatusWidget.ts` by simplifying height calculations within the `layout` and `_renderBody` methods. This **layout improvement** ensures the widget displays correctly, enhancing the visual presentation of CI statuses. The change primarily impacts the user interface of the **CI integration features**, providing a more stable and accurate display. | Mar 27 | 1 | waste |
| 764a4500 | This commit **fixes** and **refactors** the **CI status widget layout** by simplifying its rendering logic. It removes redundant height calculations within the `layout` and `_renderBody` functions in `ciStatusWidget.ts`, instead directly passing the necessary height to the internal list component. This **maintenance** work addresses potential display issues and improves the robustness of the widget's presentation. Users will experience a more stable and correctly rendered **CI status widget** within the sessions/changes contribution. | Mar 27 | 1 | waste |

| 9a61fdbe | This commit introduces a **new capability** allowing users to **edit existing PR/code review comments** directly within the `agentFeedback` system. Upon saving an edited comment, it is **automatically converted into agent feedback**, streamlining the feedback submission process. The change primarily affects the **`agentFeedback` contribution**, specifically within `src/vs/sessions/contrib/agentFeedback/browser/agentFeedbackEditorWidgetContribution.ts`. This work also includes a **refactoring** of the underlying edit action handling logic, improving the maintainability of functions like `_startEditing` and `_convertToAgentFeedback`. This enhancement provides users with greater flexibility to refine their feedback, ensuring all modifications are captured as structured agent feedback. | Mar 27 | 1 | grow |
| c7994ae5 | This commit introduces a **new feature** that allows users to explicitly **set the title of Copilot CLI chat sessions**. It registers the `github.copilot.cli.sessions.setTitle` command within the **Copilot extension's chat sessions module**, enabling programmatic control over session naming, even for initially untitled sessions. This enhancement significantly improves **session management and organization** by providing a mechanism to assign descriptive titles. While not exposed in the command palette, this command facilitates integration with other UI elements or applications for a more structured user experience. A new localized string for the command's display name is also included. | Mar 27 | 4 | grow |
| 6bfb9bcc | This commit performs **maintenance** by adding the previously missing `since` property to `IAgentSessionApprovalInfo` literals. It specifically updates the test data within the `src/vs/workbench/test/browser/componentFixtures/agentSessionsViewer.fixture.ts` file, ensuring that the **workbench's agent sessions viewer test fixtures** conform to the expected interface. This **fix** improves the **robustness and correctness of the testing infrastructure** by aligning test data with the current type definition, preventing potential test failures or inconsistencies. | Mar 27 | 1 | maint |
| afbafa7a | This commit provides a **maintenance fix** by updating various **session-related test suites** to correctly handle the `mainChat` property within the `ISessionData` object. Specifically, it modifies test helper functions like `makeSession`, `createSession`, `makeAgentSession`, and `makeNonAgentSession` across the `chat`, `sessions`, and `terminal` contributions to include or adjust the `mainChat` field. This ensures that **unit tests** for **session configuration, session listing, and terminal integration** remain valid and pass after recent schema changes to the `ISessionData` interface. The fix prevents test failures and maintains the reliability of the test suite. | Mar 27 | 3 | maint |
| 70072c5e | This **maintenance enhancement** introduces a **timestamp (`since` property)** to the `IAgentSessionApprovalInfo` interface within the **`chat` subsystem**, recording precisely when an agent session was approved. Concurrently, the **`sessions` subsystem's UI components** in `src/vs/sessions/contrib/sessions/browser/views/sessionsList.ts` have been **refactored** to update their approval retrieval logic. This update now leverages a new helper, `getFirstApprovalAcrossChats`, ensuring the display correctly handles the enriched approval information. The change provides more granular data for agent session approvals, potentially enabling future features or improved auditing based on approval timing. | Mar 27 | 2 | maint |
| f11491d1 | This commit introduces a **new capability** to the **sessions changes view**, displaying the agent feedback count for individual files. It modifies `src/vs/sessions/contrib/changes/browser/changesView.ts` to inject an `IAgentFeedbackService`, process feedback data using `agentFeedbackCountByFileObs`, and render the counts via `ChangesTreeRenderer`. Complementary styling for the new feedback badge is added in `src/vs/sessions/contrib/changes/browser/media/changesView.css`. This enhancement provides users with immediate visual context regarding agent feedback directly within the file list of the changes view. | Mar 27 | 2 | grow |
| 26626427 | This commit introduces the **capability to rename and delete individual chat sessions**, significantly enhancing user control over their session history. It **implements the necessary UI** within the `SessionCompositeBar` for these actions, including context menu integration. The **core session management service** (`ISessionsManagementService`) is **refactored** to expose dedicated `deleteChat` and `renameChat` methods, and the `ISessionData` interface is updated with a `mainChat` property to identify primary chats within a session group. Additionally, specific logic is added to the `copilotChatSessionsProvider` to differentiate and correctly handle deletion and renaming for **Copilot CLI sessions**, ensuring consistent behavior across various session types. | Mar 27 | 4 | grow |
