@molecule/api-agent-transcript-cursor

Cursor transcript reader for @molecule/api-agent-transcript.

Reads the Markdown file Cursor's "Export Chat" writes (the chat panel's ⋯ menu) into a normalized AgentSession: each **User** block is what you typed, each **Cursor** block is the reply.

Auto-generated, AI-first package reference for the molecule.dev ecosystem. It is written to be read by coding agents as much as by people, and is generated from this package's source — edit src/index.ts JSDoc, not this file.

Quick Start

import { readFileSync } from 'node:fs'
import { readTranscript, setProvider } from '@molecule/api-agent-transcript'

const file = 'cursor_debugging_session.md'
const session = readTranscript({ text: readFileSync(file, 'utf8'), fileName: file })
console.log(session.harnessVersion, session.turns.length)

Runtime Dependencies

@molecule/api-agent-transcript
The export names no model and records no file writes — Cursor leaves tool calls out of it — so every turn's model is unset and files empty.
harnessVersion is the Cursor version in the _Exported on … from Cursor (x.y.z)_ line. The date on that line is in the exporting machine's locale and is not read.
Only a **User** or **Cursor** line on its own splits turns, and the --- rule before each is dropped; a reply's own --- rules stay.
Detection needs the # title line followed by the _Exported on … from Cursor_ line, so a hand-written chat with **User** headings is not taken for a Cursor export.
Format read off real exports from Cursor 1.1.7, 2.1.46 and 2.3.41 (2026-09-29); Cursor itself is closed source.
