• Replace with the current /maxsim:quick --todo workflow that uses GitHub Issues as the sole source of truth

This page states GitHub Issues are the sole source of truth and that “no local files are involved”, but the current quick todo workflow still initializes and maintains a local cache under .planning/todos/* (and can fall back to local-only when GitHub isn’t available). Update this text to match the actual behavior (or update the workflow if the intent is to remove the local cache).

Suggested change

	Todo management uses GitHub Issues as the sole source of truth. Todos are created as Issues with the `todo` label and closed when completed — no local files are involved.
	Todo management uses GitHub Issues as the primary source of truth. Todos are created as Issues with the `todo` label and closed when completed. A local cache under `.planning/todos/` is maintained to speed up operations and allow limited use when GitHub is temporarily unavailable, and is synchronized with GitHub when possible.

The description implies --todo always creates/uses GitHub Issues, but the canonical command spec indicates GitHub is primary with a local .planning/todos/* cache and a local-only fallback when GitHub isn’t available. Consider updating the wording here to reflect that behavior so the website docs stay consistent with the command template.

Suggested change

	description: `Capture a task or idea as a GitHub Issue (label: todo). Use --todo list to view open todos, --todo done N to close Issue #N, or --todo triage to prioritize against the roadmap.`,
	description: `Capture a task or idea as a todo. Uses GitHub Issues (label: todo) when available with a .planning/todos/* cache, and falls back to local-only todos if GitHub can't be reached. Use --todo list to view open todos, --todo done N to mark todo N done, or --todo triage to prioritize against the roadmap.`,

[Copilot]

This row says todo capture happens “as a GitHub Issue”, but the current --todo workflow uses GitHub as the primary target with a local .planning/todos/* cache and can fall back to local-only if GitHub isn’t configured/available. Consider adjusting the wording to avoid implying GitHub is always required.

Suggested change

	| `/maxsim:quick --todo "desc"` | Capture an idea as a GitHub Issue | Think of something during a session |
	| `/maxsim:quick --todo list` | List pending todos from GitHub | Review captured ideas |
	| `/maxsim:quick --todo "desc"` | Capture an idea as a todo (GitHub Issue when configured, otherwise local) | Think of something during a session |
	| `/maxsim:quick --todo list` | List pending todos (from GitHub or local cache) | Review captured ideas |
