Tool reference

Thirty tools, all scoped to Flow sites. Read tools are safe to call freely; write tools take the revision of whatever they are changing.

Conventions

Every tool takes flow_site_id except list_flow_sites, create_flow_site and get_flow_webflow_rules; for verify_flow_section it is optional.
Writes return a receipt — the id and the new updated_at — not the source that was sent. When a write moves other sections, their new revisions come back in moved.
Section and stylesheet writes are also held to the site's design system and refused with HTFLOW_DESIGN_SYSTEM_VIOLATED if they type out a colour, font, font size, spacing, radius or shadow instead of using a token, use a token that does not exist, or restyle a shared class. The refusal lists the site's token names so it can be fixed in one pass. An edit is refused only for what it introduces, so older sections stay editable.
Every update and delete takes the updated_at revision of its target. A stale revision is refused.
Section writes are checked against the Webflow rulebook and rejected with HTFLOW_WEBFLOW_RULES_VIOLATED if they fail.

Tool	Title	What it does
`list_flow_sites`	List Flow sites	List every Flow/Webflow site this user can access.
`create_flow_site`	Create Flow site	Create a raw HTML/CSS/JS Flow site with a blank Home page.
`get_flow_site`	Read Flow site	Read the site's outline: tokens, globals, publish state, pages and their ordered section ids, titles and revisions. No section source unless include_source is set.
`delete_flow_site`	Delete Flow site	Permanently delete a Flow site using its latest revision. Only its workspace owner/admin may do this.
`publish_flow_site`	Publish Flow site	Publish the site at a subdomain of htflow.dev, or move it to a new one. Uses the app's own publishing route.
`unpublish_flow_site`	Unpublish Flow site	Take the site offline. Its subdomain stays reserved, so publishing again restores the same address.

Tool	Title	What it does
`get_flow_webflow_rules`	Read Flow rulebook	Read the mandatory Webflow-compatible HTML/CSS/JavaScript authoring rules enforced by Flow writes.
`audit_flow_site`	Audit Flow site	Audit sections against enforced Webflow rules and report token consistency signals. Pass page_id to audit one page.
`verify_flow_section`	Verify Flow section	Check a section against the rulebook and, given flow_site_id, the design system — without writing it. Returns exactly what a write would be refused for.

Tool	Title	What it does
`list_flow_pages`	List Flow pages	List ordered pages and revisions without section source.
`get_flow_page`	Read Flow page	Read one page and its ordered sections, optionally including source.
`build_flow_page`	Build Flow page	Create a page's sections in one call, and the page itself with new_page. All sections are checked first; nothing is written unless every one passes.
`create_flow_page`	Create Flow page	Create one page in a Flow site.
`update_flow_page`	Update Flow page	Rename or re-slug a Flow page with optimistic concurrency.
`delete_flow_page`	Delete Flow page	Delete a page and its sections. A Flow site must keep at least one page.

Tool	Title	What it does
`list_flow_sections`	List Flow sections	List a page's ordered section summaries and revisions.
`get_flow_section`	Read Flow section	Read exact HTML, CSS, JavaScript and revision. Always call before editing.
`inspect_flow_section`	Inspect Flow elements	List stable selectors and element structure before element-level edits.
`create_flow_section`	Create Flow section	Create one Webflow-compatible raw HTML/CSS/JS section. Non-compliant writes are rejected. Pass global_slot to make it the site's header or footer in the same call.
`update_flow_section`	Update Flow section	Atomically update section source/title using its latest revision.
`delete_flow_section`	Delete Flow section	Permanently delete one section using its latest revision.
`reorder_flow_section`	Reorder Flow section	Move one section to a new zero-based position. The page is renumbered so the order is exact, and every moved section's new revision is returned.

Tool	Title	What it does
`add_flow_element`	Add Flow element	Insert an element relative to one selector and optionally replace complete section CSS/JS.
`update_flow_element`	Update Flow element	Edit one exactly-matched element and optionally replace complete section CSS/JS.
`remove_flow_element`	Remove Flow element	Remove one exactly-matched element and optionally replace obsolete CSS/JS.

Tool	Title	What it does
`get_flow_design_tokens`	Read Flow design tokens	Read the site's design tokens plus its revision. A new site has none.
`set_flow_design_tokens`	Update Flow design tokens	Create, change and delete tokens: upsert by name, remove by name, or replace the set. A token still in use cannot be removed.
`get_flow_style_guide`	Read the design system	Every token with its value, the shared classes and the site stylesheet in one small read — instead of reading other sections to match their style.
`set_flow_site_css`	Set the site stylesheet	Replace the shared component classes every page uses — buttons, containers, headings, cards — written with tokens. Sections may not restyle them.
`set_flow_global_section`	Set the global header or footer	Make a section the site's header or footer so every page renders it. Pass null to clear a slot.
