Add meaningful tests for a file, module, or function that lacks them — auto-detect the project's test framework and conventions, cover the happy path, edge cases, and error paths, then run the suite to confirm the new tests pass and actually exercise the target code.

Stage the right changes, write a conventional commit derived from the actual diff, push to a fresh branch (never straight to main/master), and open a PR with gh including a summary and test plan; falls back to printing the push command and PR URL when gh is missing or the remote is not GitHub.

Run a failing test, read its trace, locate and fix the real root cause in the source (not the test), then re-run until green. Detects the runner (vitest/jest/pytest/go test/swift test/cargo test). Use when a test or test command is failing, a CI check is red, or you need to diagnose and fix a broken spec without weakening it.

Notarize and staple a Developer-ID-signed macOS app or .dmg for distribution outside the App Store; submit with notarytool --wait using a stored keychain credential profile, staple the ticket, verify with stapler/spctl, and read the notary log on rejection. macOS + Xcode only.

Review the current uncommitted or branch diff before it ships: pull the diff with git, read changed files for context, and report correctness bugs, missing error handling, security issues, and test gaps grouped by severity, each with file:line and a concrete fix. Use before committing, opening a PR, or when asked to "review my changes / diff / branch." Read-only by default.

Build and test a Swift Package Manager package on macOS: run `swift build` then `swift test`, parse compiler and test failures, fix the source, and re-run until the build is clean and all tests pass. Use when asked to build/test/fix a Swift package, get a SwiftPM target green, or triage failing `swift test` output.

Safely bump project dependencies for any detected ecosystem (npm/pnpm/yarn/bun, pip, cargo, go, SwiftPM): update within semver-safe ranges or a single named package, reinstall, then run build and tests to verify nothing broke — reverting or flagging on failure and summarizing what changed plus breaking notes.

Build an Xcode scheme with xcodebuild, surface compile/link errors, fix the source, and re-run until BUILD SUCCEEDED. Use when asked to build, compile, or fix build errors in a macOS/iOS Xcode project, or to verify Swift/Obj-C changes compile.

Build, debug, package and deploy SharePoint Framework (SPFx) web parts, extensions and apps for SharePoint Online and Microsoft Teams.
