How it works

Methodology

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.

Relationship to Growth / Maintenance / Fixes

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.

Proposed API Endpoint

Currently computed client-side from commit and bug attribution data. Ideal server-side endpoint:

POST /v1/organizations/{orgId}/investment-quality
Content-Type: application/json

  "endTime": "2025-12-31T23:59:59Z",
  "bucketSize": "BUCKET_SIZE_MONTH",
  "groupBy": ["repository_id" | "deliverer_email"]

4d90dceThis commit introduces a **new `ClientID` field** to the `App` struct within the **GitHub integration module**, enabling the system to store the unique client identifier for GitHub Applications. This **enhances the `App` model** by providing a dedicated attribute for this crucial piece of information, which is essential for various authentication and API interaction scenarios. A corresponding `GetClientID` accessor method has been added to safely retrieve this new field, along with a dedicated test case to ensure its correct functionality. This **new feature** lays the groundwork for future capabilities that depend on identifying GitHub Apps by their client ID.Mar 33grow
4767af9This commit delivers a **bug fix** for **GitHub organization custom properties**, specifically addressing an issue with multi-select property default values. Previously, the `DefaultValueStrings` function in `github/orgs_properties.go` did not correctly handle default values when they were of type `[]any`, leading to potential data type mismatches. The update ensures proper processing of these values, and new test cases have been added to `github/orgs_properties_test.go` to validate the fix and enhance coverage for multi-select custom properties. This change guarantees that custom property default values are consistently and correctly applied, improving the reliability of organization settings.Jan 202maint
cacc10bThis commit **refactors** the Go module caching within the **CI/CD test workflow** by updating the `.github/workflows/tests.yml` configuration. It specifically leverages the built-in `cache-dependency-path` feature of the `setup-go` action to manage Go module dependencies. This **chore** improves the efficiency and reliability of caching during test runs, streamlining the CI process. The change ensures more consistent and potentially faster execution of tests by utilizing a more robust and integrated caching strategy.Jan 201maint
5458fbcThis commit **enhances the handling of custom property defaults** within the **GitHub integration**, specifically for **organization custom properties**. It **introduces a breaking change** by making `CustomProperty.DefaultValue` type `any` and `CustomProperty.ValueType` type `PropertyValueType` to support more flexible default values. To manage this, the change **adds type-safe accessor methods** such as `DefaultValueString`, `DefaultValueStrings`, and `DefaultValueBool` to `github/orgs_properties.go`. This **refactoring** improves the robustness and flexibility of **custom property management** by providing explicit type handling for default values, requiring updates to existing code that directly accesses `DefaultValue`.Jan 146maint
4456d12This commit provides a **bug fix** for the **GitHub integration**, specifically addressing how **pull request rule parameters** are handled during JSON serialization. It modifies the `PullRequestRuleParameters` struct in `github/rules.go` to ensure the `AllowedMergeMethods` field is **omitted from JSON output if it is empty or unset**. This change prevents potential issues when processing or storing GitHub rules where merge method restrictions are not explicitly defined, improving the robustness of **rule configuration and application**.Jan 82waste
e119eb8This commit introduces a **new feature** by adding a **'repository' target to the GitHub ruleset integration**, allowing for the definition of rules that apply directly to repositories. It significantly updates the `github` package, specifically `github/rules.go`, to define new repository-specific rule types and adjust JSON marshaling/unmarshaling to support them. New accessor methods like `GetRepositoryCreate` and `GetRepositoryVisibility` are added in `github/github-accessors.go` to retrieve parameters for these new repository-level rules. This enhancement provides more granular control over repository actions such as creation, deletion, transfer, and visibility within the ruleset system.Dec 44grow
841abaeThis commit primarily performs a **maintenance update** by upgrading the project's **`golangci-lint` tool to version v2.7.0**, ensuring the use of the latest static analysis features. This involves updating the version specified in `.custom-gcl.yml` and `script/lint.sh`, and adding `custom-gcl.exe` to `.gitignore` to support Windows environments. Concurrently, a **refactoring** is applied to the `tools/gen-release-notes` utility, specifically modernizing string manipulation in `stripPRHTML` and `getTagSequence` using `strings.Cut`. This dual-purpose commit enhances the **CI/CD linting process** and improves the internal code quality of the **release notes generation tool**.Dec 44maint
d08bec9This commit **introduces new API operations** by updating the `openapi_operations.yaml` specification, marking a significant **feature enhancement**. It expands the API surface to include functionalities across various domains such as **enterprise actions, app installations, billing, organization actions, dependabot, attestations, repository actions, issue dependencies, and user attestations**. This update provides developers with a broader set of tools to interact programmatically with these subsystems, ensuring the API documentation accurately reflects the latest available capabilities. The commit also synchronizes the OpenAPI commit hash, reflecting the most current upstream specification.Aug 81grow
6540c41This commit **fixes** a potential type mismatch by **changing the `AppID` field** within the **`github/checks` package** from `int` to `int64`. This **breaking change** primarily affects the `ListCheckSuiteOptions` struct and the `GetAppID` accessor method, which now consistently return `int64`. The update ensures proper handling of application identifiers, aligning the client library with the underlying GitHub API's expected data types and preventing potential overflow issues. Consequently, consumers of these types and methods will need to adjust their code to use `int64` for application IDs.Jul 224maint
d96da2eThis commit introduces a **new capability** to the **GitHub client library**, allowing users to **disable the client's internal rate limit checking mechanism**. A new `DisableRateLimitCheck` field has been added to the `Client` struct, which, when enabled, causes the `bareDo` method to conditionally skip all rate limit checks and updates. This provides greater control for users who manage rate limiting externally or interact with GitHub Enterprise instances, and is supported by new unit tests. The **documentation** in `README.md` has been updated to explain this new option and its interaction with other rate limit bypass features.Jun 303maint
ce3a839This commit provides a **maintenance fix** to the **CI/CD pipeline** by updating the **GitHub Actions workflow** in `.github/workflows/tests.yml`. It specifically enables OIDC authentication and grants the required permissions for **Codecov uploads**. This resolves previous issues with code coverage reporting, ensuring that accurate test coverage metrics are consistently available for the project.Jan 201waste
2db75deThis commit **introduces a new `REVIEWERS` file** to the project, which lists GitHub usernames of individuals available for pull request reviews.
