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.

| fd56349 | This commit introduces `prompt_0206` as a **feature enhancement** for the **Copilot extension's AI agent**. It updates `extensions/copilot/src/extension/prompts/node/agent/vscModelPrompts.tsx` to include new principles for verification, debugging, and testing anti-patterns, along with detailed channel usage and order instructions, aiming to refine the AI model's behavior. Concurrently, the `extensions/copilot/src/platform/endpoint/common/chatModelCapabilities.ts` file is updated to **adjust model hash lists**, specifically moving one hash and adding another to `VSC_MODEL_HASHES_A`. This ensures the enhanced prompting logic is correctly applied to the designated AI models, ultimately improving the **AI agent's understanding and response quality** in complex development tasks. | Feb 24 | 2 | grow |
| 7d076d4 | This commit performs a **refactoring** of how **Copilot chat model capabilities** are managed by reorganizing model hashes. It specifically **moves and rebalances model hashes** between the `VSC_MODEL_HASHES_A`, `VSC_MODEL_HASHES_B`, and `VSC_MODEL_HASHES_SUBSET_C` constant arrays within `extensions/copilot/src/platform/endpoint/common/chatModelCapabilities.ts`. This internal adjustment aims to streamline the management of model identifiers, likely improving maintainability and preparing for future updates to Copilot's underlying chat models. The change is purely an internal structural improvement and does not alter external behavior or introduce new features. | Jan 15 | 1 | maint |
| fde238f | This commit introduces a **feature update** to the **Copilot extension** by enhancing the system prompt for `VSCModelPromptB` in `extensions/copilot/src/extension/prompts/node/agent/vscModelPrompts.tsx`. The updated prompt now includes **new parallel tool use instructions** and **revised output formatting guidelines**, aiming to improve the model's response generation and structure. Concurrently, it performs a **refactoring** in `extensions/copilot/src/platform/endpoint/common/chatModelCapabilities.ts` to reorganize model hash management, moving specific hashes to `VSC_MODEL_HASHES_B` and updating `VSC_MODEL_HASHES_SUBSET_C`. This work collectively refines the model's operational instructions and internal categorization. | Jan 7 | 2 | grow |
| acfb9d3 | This commit **refactors the prompt registration order** within the **Copilot extension's agent prompt system**. Specifically, it reorders the import of `vscModelPrompts` in `extensions/copilot/src/extension/prompts/node/agent/allAgentPrompts.ts` to ensure its prompt resolvers are registered *before* `gpt5Prompt`. This **maintenance change** is crucial for establishing the correct precedence among different prompt sources, thereby ensuring the **Copilot agent resolves prompts accurately and consistently**. The adjustment prevents potential conflicts and clarifies the intended prompt resolution hierarchy for improved reliability. | Dec 15 | 1 | maint |
| 03e3903 | This commit **disables** the `apply_patch` edit tool specifically for the **VSC Model C** within the **Copilot extension**. It modifies the `modelSupportsApplyPatch` and `modelCanUseApplyPatchExclusively` functions in `extensions/copilot/src/platform/endpoint/common/chatModelCapabilities.ts` to prevent this model from utilizing the patch application feature. This is a **maintenance fix** to ensure proper feature compatibility and prevent potential issues when `VSC Model C` is in use. Consequently, users interacting with `VSC Model C` will no longer be offered or able to use the `apply_patch` functionality. | Dec 12 | 1 | waste |
| 67d2fc3 | This commit **introduces support for a new VSC model subset, 'C'**, within the **Copilot extension's chat model capabilities**. It **adds new functionality** by integrating specific logic in `chatModelCapabilities.ts` to determine if this model supports replace strings. This involves updating functions like `modelSupportsMultiReplaceString` and `modelCanUseReplaceStringExclusively` to recognize `isVSCModelC`, thereby **enhancing the system's compatibility and feature set** for different VSC model configurations. | Dec 3 | 1 | grow |
| abadbab | This commit **refactors** the internal management of **chat model capabilities** within the **Copilot extension**. It specifically **moves model hashes** from the `VSC_MODEL_HASHES_B` constant to `VSC_MODEL_HASHES_A` in `extensions/copilot/src/platform/endpoint/common/chatModelCapabilities.ts`, subsequently emptying `VSC_MODEL_HASHES_B` for future assignments. This change streamlines how different model versions are identified and categorized, improving the clarity and maintainability of the Copilot endpoint's model selection logic. | Nov 27 | 1 | maint |
| 924f025 | This commit **enhances the Copilot extension's model identification system** by introducing support for a new "hidden family" of VSC models. It updates the **chat model capabilities** within `extensions/copilot/src/platform/endpoint/common/chatModelCapabilities.ts` to recognize these new models. Specifically, new model hashes are added to `VSC_MODEL_HASHES_A` and `VSC_MODEL_HASHES_B`, and functions like `isVSCModelA` and `modelSupportsApplyPatch` are modified to check both model ID and family hashes. This **feature enhancement** ensures that new VSC models are correctly identified and their specific capabilities, particularly concerning patch application, are accurately determined, paving the way for their proper utilization. | Nov 14 | 1 | grow |
| 0c0c946 | This commit introduces **support for a new VSC Model B** by adding dedicated prompt variants and resolvers within the **Copilot extension's prompt system**. It **refactors** the existing generic VSC model identification into specific `VSCModelPromptA` and `VSCModelPromptB` types, along with corresponding `isVSCModelA` and `isVSCModelB` capability checks in `chatModelCapabilities.ts`. This allows the agent prompt logic in `agentPrompt.tsx` to dynamically include preambles tailored to each model, thereby **improving the system prompts** for both VSC Model A and Model B. The change enables the extension to adapt its behavior more precisely based on the specific VSC model in use. | Nov 5 | 3 | grow |
| e03b9c6 | This commit introduces **custom prompt handling** for **hidden VSC models** within the **Copilot extension's agent system**. It adds a new `VSCModelPromptResolver` and associated prompt elements (`vscModelPrompts.tsx`) to provide specific system prompts, preamble messages, and a reminder function (`agentPrompt.tsx`) tailored for these models. The change also includes logic to identify VSC models (`chatModelCapabilities.ts`) and **refactors** prompt resolution to use the `models` property, reducing code duplication. This **new capability** ensures that specific VSC models receive appropriate contextual instructions, improving their performance and interaction within the agent system. | Oct 23 | 4 | grow |
