trident

Returns the complete Trident 2D specification including grammar, syntax rules, coordinate system, containers, nodes, connections, shapes, and icon reference. Use this when you need deep understanding of the Trident DSL.

{
  "type": "object",
  "properties": {},
  "required": []
}

Returns LLM-optimized instructions for generating Trident diagrams, including quick reference, critical rules (especially Y-axis!), spacing guidelines, common patterns, color conventions, and error prevention checklist. Use this before generating any Trident diagram.

{
  "type": "object",
  "properties": {},
  "required": []
}

Returns a comprehensive Trident example demonstrating all syntax features including containers, nodes (traditional and bracket-style syntax), diamond/rectangle shapes, icons, connections with labels, routing modes, cards, and text annotations. Use this to see all features in action.

{
  "type": "object",
  "properties": {},
  "required": []
}

Returns a comprehensive validation checklist for Trident diagrams covering syntax rules, semantic rules, best practices, and common mistakes to avoid. Use this after generating a diagram to verify correctness.

  "type": "object",
  "properties": {
    "diagram": {
      "type": "string",
      "description": "Optional: The Trident diagram code to include context-specific validation tips"
    }
  }
}

Returns a condensed 2-minute quick-start guide with minimal working examples, core syntax reference, and key concepts. Use this for rapid learning when you need to generate simple diagrams quickly.

  "type": "object",
  "properties": {},

}

Opens a live Trident document and returns its full contents as Trident markup DSL — the human-readable text format used to author diagrams. Use this to READ and UNDERSTAND the diagram: its structure, labels, connections, and layout. Do NOT rely on this to enumerate entity IDs for programmatic use — the DSL can be very large and the output may be truncated. To get a complete, structured list of all entity IDs and counts, use get_document_summary instead. Requires a valid access token.

{
  "type": "object",
  "properties": {
    "token": {
      "type": "string",
      "description": "Access token for this document. The document ID is embedded in the token."
    },
    "agentId": {
      "type": "string",
      "description": "YOUR AI assistant name (e.g. \"Claude.ai\", \"GitHub Copilot\"). Shown as \"[agentId] working with [userName]\" in the collaboration presence dot."
    },
    "userName": {
      "type": "string",
      "description": "First name of the human you are assisting (ask them at session start if you do not know). Shown in the collaboration presence dot as \"[agentId] working with [userName]\"."
    }
  },
  "required": [
    "token"
  ]
}

Returns a complete structured summary of a Trident document as JSON: all node IDs, container IDs, connection IDs, annotation IDs, labels, and entity counts. Use this for PROGRAMMATIC OPERATIONS — it is never truncated regardless of diagram size, so you always get every entity ID. Use this before any bulk update, delete, or enumeration task. To read and understand the diagram as a human-readable diagram, use open_document instead. Requires a valid access token.

{
  "type": "object",
  "properties": {
    "token": {
      "type": "string",
      "description": "Access token for this document. The document ID is embedded in the token."
    }
  },
  "required": [
    "token"
  ]
}

Returns the recent change history for a live Trident document. Each entry shows who made the change, what was changed, and when. Useful for understanding what edits have been made by AI agents or human collaborators. Requires a valid access token.

  "type": "object",
  "properties": {

      "type": "string",
      "description": "Access token for this document. The document ID is embedded in the token."

      "description": "Optional: Maximum number of entries to return (default 100, max 500)"
    }
  },
  "required": [
    "token"
  ]
}

Adds a new node (entity) to a live Trident document. The node appears immediately for all collaborators. Requires a valid editor access token. Before adding nodes: call open_document to understand the diagram layout and pick sensible positions; call get_document_summary to get all existing entity IDs so you can avoid duplicates. IMPORTANT: if this node belongs inside a container, pass node.container on THIS call — do NOT create the node without a container and reparent it later via update_node. Orphaned nodes appear immediately to all live collaborators and create unnecessary visual churn.

Renders the current state of a live Trident document as a PNG image directly from the Yjs collaborative session — bypassing Firestore, which may be stale. Returns a base64-encoded PNG. Use this to visually verify that diagram edits look correct before or after making changes.

Adds a text annotation to a live Trident document. Two visual styles: style:stickyNote (default — post-it card with colored background, good for notes/callouts) or style:textBody (plain transparent text, good for diagram titles and section labels). Ideal for architectural notes, decision records, section labels, or TODO markers. Appears immediately for all collaborators. Requires a valid editor access token.

Removes a text annotation from a live Trident document. Use get_document_summary to get all annotation IDs before calling this. Requires a valid editor access token.

Repositions or resizes a background image (canvas graphic) in a live Trident document. Use open_document to get the canvas graphic ID and current dimensions — it appears as: image <id> "<url>" at (x, y) width:W height:H. The position at (x, y) is the TOP-LEFT corner. USE THIS BEFORE placing many geographically-positioned nodes: if the background map is small (e.g. width < 700), scale it up so nodes have room to breathe and do not overlap. Requires a valid editor access token.

Posts a visible suggestion to human collaborators watching the document WITHOUT making any changes to the diagram. Use this when you observe something worth flagging — a potential mistake, an improvement, or a question — but want the human to decide. The suggestion appears as a bold "SUGGESTION:" callout in the UI with a radar pulse animation on your presence dot for 10 seconds. Does NOT mutate the diagram. Requires a valid viewer or editor access token.

Delivers an explanation payload to human collaborators watching the document, optionally anchored to a specific node or container. Use this when you want to explain what a diagram element represents, why it exists, or how it relates to other parts of the system — without suggesting a change. The explanation appears in the UI attributed to you. Does NOT mutate the diagram. Requires a valid viewer or editor access token. IMPORTANT: this tool automatically pauses (3–15 s, proportional to explanation length) before returning, so the human has time to read. Do NOT add your own artificial delays between explain calls — the pacing is built in.
