.opencode/gsd-core/workflows/help.md

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 <topic> (or -b <topic>)	workflows/help/modes/topic.md in compact scope (signature + one-line summary of the matched section)
anything else — bare topic, --full <topic>, 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 <reference> block content directly. No additions, no project context, no suggestions.
