Requirements and assumptions

• LM Studio attaches a working directory to the prediction context.
• The working directory path is expected to be: <LM_HOME>/working-directories/<chat_id>
• The chat_id is exactly 13 digits (e.g., 1758816879741) and must match the working directory name.
• The source JSON is expected at: <LM_HOME>/conversations/<chat_id>.conversation.json

This plugin is intentionally strict and deterministic: if the SDK working directory is missing or does not match the expected layout, the export fails with a clear error message (no heuristics / no fallback scanning).

How to use

• Run:

• export_chat {}

Outputs:

• <chat_id>.conversation.json (refreshed into the working directory; always overwritten)
• <chat_id>.conversation.md (Markdown export)
• Optionally: <chat_id>.conversation.messages.json (messages only)

Tool details

• export_chat
  • Parameters:
    • overwrite (boolean, default: true) — Overwrite outputs if they exist.
    • include_thinking (boolean, default: true) — Include “thinking” blocks as collapsible
      .
    • include_tool_calls (boolean, default: true) — Include tool calls as pretty-printed JSON.
    • emit_messages_json (boolean, default: false) — Also write messages-only JSON.
    • embed_images (boolean, default: true) — Embed local images from the chat working directory into the Markdown as data: URIs.

Conversion behavior

• Uses the last version of each message (assumed to be the latest).
• Renders roles as Markdown sections:
  • User, System, Tool
  • For assistant messages, the heading uses the model (e.g., senderInfo.senderName), or “Assistant” if unknown.
• Strips known control markers like: <|start|>assistant<|channel|>final<|message|> and <|channel|>final<|message|>

Image handling

• Attachments: embedded when the message contains base64 / metadata-derived previews.
• Chat working directory images: by default embedded into the Markdown (data: URIs) so the .md stays portable when moved out of the chat folder.
• If you disable embedding (config embedImages=false or tool param embed_images=false), the Markdown will keep relative links, which only work as long as the .md remains in the chat working directory.
