Display GSD command help at the tier the user asked for. Output ONLY the reference content of the chosen mode. Do NOT add project-specific analysis, git status, next-step suggestions, or any commentary beyond the reference. **Mode files are lazy-loaded.** Read only the one mode file that matches `$ARGUMENTS`, then output its `` body verbatim. | When `$ARGUMENTS` is | Read | |---|---| | `--brief` (or `-b`) alone | `workflows/help/modes/brief.md` | | `--full` (or `-f`, `--all`) alone | `workflows/help/modes/full.md` | | empty / unset | `workflows/help/modes/default.md` | | `--brief ` (or `-b `) | `workflows/help/modes/topic.md` in compact scope (signature + one-line summary of the matched section) | | anything else — bare topic, `--full `, or topic with leading `--` | `workflows/help/modes/topic.md` in full scope (entire matched section) | Argument parsing rules: - Trim and lowercase `$ARGUMENTS`. - Recognize the long form, short form, and obvious aliases listed above. - A bare token like `debug`, `--debug`, `capture`, `workflow`, `config` is a topic — route to `topic.md`. - Multiple flags: `--brief` and `--full` are mutually exclusive — if both appear *without* a topic, prefer `--full`. - `--brief` combined with a topic invokes `topic.md` in compact scope; `--full` combined with a topic invokes `topic.md` in full scope (the default topic behavior). When passing arguments through to `topic.md`, retain the `--brief` flag so the mode can pick the right scope. After loading the chosen mode, emit its `` block content directly. No additions, no project context, no suggestions.
