🏗️ Architecture Diagram:Architecture Diagram - Incremental Update (2026-03-12)

[github-actions]

This is an incremental update triggered by Go file changes since the last architecture analysis (commit 9f0be69). All existing pkg/ and cmd/ packages were analyzed — no structural changes detected. The architecture diagram remains current.

Changed Packages Since Last Run

All 20 packages had code-level changes, but none altered the architectural layer structure or inter-package dependency graph:

cmd/gh-aw, cmd/gh-aw-wasm, pkg/cli, pkg/console, pkg/constants, pkg/envutil, pkg/fileutil, pkg/gitutil, pkg/logger, pkg/mathutil, pkg/parser, pkg/repoutil, pkg/sliceutil, pkg/stringutil, pkg/styles, pkg/testutil, pkg/timeutil, pkg/tty, pkg/types, pkg/workflow

Additionally, two new build-tool packages were introduced under internal/tools/ (not part of the main architecture):

• internal/tools/actions-build — builds GitHub Actions assets
• internal/tools/generate-action-metadata — generates action metadata

Change Log

• Packages modified: All 20 pkg/ and cmd/ packages had code updates (primarily pkg/cli and pkg/workflow)
• New packages: internal/tools/actions-build, internal/tools/generate-action-metadata (build tools only, not in main architecture)
• Dependencies: No new cross-package imports detected
• Structural shifts: None — layer assignments unchanged
