Workspace Landing Page Editor

The workspace landing page (rendered at /w/:slug) is a single self-contained HTML blob stored on workspace.landing_page_html. It is generated from scratch by the server-side LANDING_PAGE_PROMPT whenever a brief is submitted — that path overwrites the HTML wholesale.

For ANY change that should not regenerate the whole page (typography tweaks, layout edits, adding a section, changing copy, swapping an image, fixing a tagline), edit the HTML directly and write it back. Do NOT send a brief unless the user wants a full regeneration.

All commands use the astria CLI (see the astria-api skill). Pass -w <workspace_id> to target the workspace.

Constraints carried over from LANDING_PAGE_PROMPT

When editing, preserve these invariants (the live /w/:slug page depends on them):
