Agentic Mermaid

Author a new Mermaid diagram from blank by folding a list of structured opsover an empty diagram of `family`. The declarative counterpart to hand-writingsource. Returns the same envelope as `mutate`:{ ok, family, source, verify } or { ok:false, family, opIndex, error }.Op kinds by family: flowchart: add_node(id, label, shape?, parent?), remove_node(id), rename_node(from, to), set_label(target, label), add_edge(from, to, label?, style?), remove_edge(id) state: add_state(id, label?, parent?), remo…

Describe a Mermaid diagram. format=text returns { ok, text } withone or two summary sentences; format=json returns { ok, tree } with the AX tree;format=facts returns { ok, facts } with deterministic semantic fact lines formachine checking (for example edge A -> B : label, member Duck +quack()).

Run synchronous JavaScript against the mermaid SDK in an isolated sandbox.Code runs as an expression or statement body — return the final value. Promise jobs,async/await, and dynamic import are not supported.Multi-step diagram edits should be one execute() call. The SDK declaration isTypeScript-shaped for guidance; the sandbox does not transpile type annotations.Hosted note: execute runs in an on-demand isolate and costs more than the directrender_svg/render_ascii/render_png/verify/describe tool…

Apply a list of structured edit ops to an existing Mermaid `source` andreturn the edited diagram. This is the declarative counterpart to `execute`:plain JSON in, plain JSON out, no sandbox. Prefer it for straightforward edits;reserve `execute` for logic the ops don't express.Returns { ok, family, source, verify:{ ok, warnings } } on success, or{ ok:false, family, opIndex, error } — where `error` names the offending fieldand lists the valid ones — when an op is malformed or cannot apply. Ops appl…
