The Agent Skills Directory

[COMMAND_EXECUTION]: The skill executes a significant number of helper binaries located in ~/.claude/skills/gstack/bin/. These utilities manage session tracking, project-specific configuration (e.g., gstack-config), and state recovery.
[COMMAND_EXECUTION]: Utilizes a browser automation tool (aliased as $B) to execute JavaScript within a local HTML rendering bundle (diagram-render.html). This is used to convert Mermaid source code into SVG, PNG, and Excalidraw formats.
[DATA_EXFILTRATION]: Includes functionality for telemetry logging and cross-machine artifact syncing. These features are documented as sharing technical metadata or project artifacts with a private repository, and they require user consent through interactive prompts.
[EXTERNAL_DOWNLOADS]: The preamble logic performs update checks by executing gstack-update-check. It also references documentation on garryslist.org and rendering services at excalidraw.com.
