Server instructions

Immutable agent diagrams. Zindex keeps every saved version exactly, so a diagram made in one conversation can be found, changed and rendered the same way later, from any MCP client. Loop: diagram_find or diagram_create, then diagram_get, diagram_edit, diagram_render. Edits need baseRevision (the revision you last read) and a one-line message. - diagram_get returns a compact outline. Pass knownRevision to get only what changed since then. - Mermaid works both ways for erDiagram and flowchart: diagram_create takes it, diagram_get view mermaid returns it, and diagram_edit takes the edited text (architecture and ER diagrams) and applies only the differences. Element IDs are the Mermaid IDs. - Retries are safe: use key on diagram_create and requestId on diagram_edit. - On REVISION_CONFLICT the error lists what changed; re-plan against the new revision. - Keep a brief of up to 1,000 characters on each diagram: what it shows, conventions to keep, decisions made. The next agent reads it first. - Element IDs are yours and stable; reuse them in ops. Skill: https://zindex.ai/skill/SKILL.md. Schemas: https://zindex.ai/schemas/scene.schema.json and https://zindex.ai/schemas/ops.schema.json. - Auto-layout is the default: leave layout off nodes and the engine places them and routes edges (text and image elements need a layout). Nodes keep their positions after the first save unless a node that grows needs the room or an edit changes their frame; new nodes go next to their neighbours, and sequence diagrams follow message order. An autoLayout op lays out again; without elements it also drops most frames' own layout. - diagram_render returns links, not images; preview adds an image. - In a code repository, save the diagram's id and revision in .zindex.json so the next session can pick it up. - When the docs and the engine disagree, or something you needed is missing, tell Zindex with diagram_share action feedback; no diagram is needed, and the user confirms it.

diagram_find

Lists this account's diagrams, most recently changed first, with id, key, title and latest revision.

Inferred read-only

diagram_get

Reads a saved diagram by id or key.

Inferred read-only

diagram_validate

Checks a DSP scene or Mermaid text without saving it.

Inferred read-only

diagram_create

Saves a new diagram from a DSP scene or Mermaid text and returns its id, revision 1, content hash and chain hash.

Inferred read-only

diagram_edit

Changes a saved diagram as a new revision; old revisions are kept.

Inferred read-only

diagram_render

Returns SVG and PNG links to a version of a saved diagram, not the image, with its hashes and engine version.

Inferred read-only

diagram_history

Lists a diagram's versions, newest first, with time, client, message, chain hash and counts of elements added, changed and removed.

Potential side effects

diagram_delete

Deletes a diagram with all its versions.

Inferred read-only

diagram_share

publish makes a diagram readable by anyone at its link; unpublish makes it private.
