Performance
Key patterns and highlights from this developer's activity.
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.

| ff26d2f5 | This commit **enhances telemetry** for terminal command execution by introducing an `exitCodeValue` field to the existing `toolUse.runInTerminal` event. This **new capability** within the **`terminalContrib/chatAgentTools`** module now reports the exact numeric exit code, replacing the less precise tri-state `nonZeroExitCode` information. The change, implemented in `runInTerminalToolTelemetry.ts`, provides more granular data for understanding command completion. This significantly improves the **observability and diagnostic capabilities** for terminal tool usage, allowing for more precise analysis of command outcomes. | Mar 31 | 1 | grow |

| 3cbe1c07 | This commit introduces **new telemetry** to the **Terminal Chat Agent Tools** to enhance understanding of user behavior. It **adds a new capability** to the `runInTerminalTool` by tracking the `requestUnsandboxedExecutionReason`, which captures the specific justification provided when an unsandboxed execution is requested. This **data collection improvement** will help analyze the scenarios and reasons behind such requests, informing future development and security considerations for the **Terminal Chat Agent**. | Mar 30 | 2 | grow |
| 7c89420b | This commit performs **maintenance** and **refactoring** by **removing** the `ChatAgentVoteDownReason` enum and all associated `voteDownReason` field references. This change impacts the **Chat** and **Inline Chat** features, specifically affecting the model, service, telemetry, and various UI layers, including the `ChatVoteDownButton` in `chatListRenderer.ts` and `inlineChatWidget.ts`. The removal streamlines the codebase by eliminating unused voting reason logic, and a **snapshot test adjustment** in `chatService.test.ts` ensures backward compatibility for data serialization. | Mar 27 | 11 | maint |

| 5367dafe | This commit introduces **telemetry logging** for changes to the `TerminalSandboxEnabled` setting, enhancing data collection within the **Telemetry module**. It adds `TerminalSandboxEnabled` to the `TerminalContribSettingId` enum, allowing the **terminal subsystem** to properly identify and report modifications to this specific setting. This **new feature** provides valuable insights into user adoption and interaction with the terminal sandbox, informing future development and improvements. | Mar 26 | 2 | grow |
| 460c5cf7 | This commit **enhances telemetry** for the **Terminal Chat Agent Tools** by introducing an `isSandbox` field to the `toolUse.runInTerminal` event. This **new capability** reports whether a command executed via the `runInTerminalTool` was run inside the **terminal sandbox**, providing a boolean (0 or 1) indicator. The change involves updating the telemetry logging logic in `src/vs/workbench/contrib/terminalContrib/chatAgentTools/browser/runInTerminalToolTelemetry.ts` and passing the sandbox status from `src/vs/workbench/contrib/terminalContrib/chatAgentTools/browser/tools/runInTerminalTool.ts`. This improvement provides crucial data for understanding user interaction patterns and the adoption of sandboxed terminal commands. | Mar 26 | 2 | grow |
