About trajectory

trajectory Normalize agent transcripts from different runtimes into one validated, model-ready record format. Agent tools represent the same concepts—messages, reasoning, tool calls, and tool results—in incompatible native formats. provides one TypeScript API that turns those formats into deterministic, structured records for training, evaluation, analysis, and inference. The caller supplies a transcript string and its source. The one exception is Deep Agents, whose sessions reads from its local LangGraph SQLite store by thread ID; see . Installation The TypeScript package is published as : Quick start contains the normalized trajectory. is always present and is empty when the transcript required no recoverable cleanup. json { "records": [ { "role": "meta", "source": "codex" }, { "role": "user", "content": "Check the current directory.", "timestamp": "2026-07-10T12:00:00.000Z" }, { "role": "assistant", "content": null, "toolcalls": [ { "id": "call1", "name": "execcommand",

How this security grade is produced

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy, covering 11 red-flag categories including credential harvesting, data exfiltration, and curl | sh installers. It is a first-layer scan, not a manual audit — we say so rather than overstate it.

The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
