save-trajectory SKILL.md skillA
save-trajectory from agenttoolkit/altk-evolve is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add agenttoolkit/altk-evolve/save-trajectory@git:20261021.2a75491Pins git:20261021.2a75491 in mdr.lock. Pin the fingerprint instead.

Save the current conversation as a trajectory JSON file in OpenAI chat completion format for analysis and fine-tuning.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Save Trajectory
## Overview
This skill saves the current session's conversation history as a JSON file in OpenAI chat completion format. The trajectory is saved to `.evolve/trajectories/` in the project root. This enables trajectory analysis, fine-tuning data collection, and session review.
## Workflow
### Step 1: Walk Through Conversation Messages
Review all messages in the current conversation from start to finish. For each message, identify its type:
- **User text messages**
- **Assistant text responses** (may include thinking)
- **Assistant tool calls**
- **Tool results**
### Step 2: Convert to OpenAI Chat Completion Format
Convert each message to the appropriate format:
**User text message:**
```json
{"role": "user", "content": "the user's message text"}
```
**Assistant text response (no thinking):**
```json
{"role": "assistant", "content": "the assistant's response text"}
```
**Assistant text response (with thinking):**
```json
{"role": "assistant", "content": "the assistant's response text", "thinking": "the thinking/reasoning text"}
```
**Assistant tool call (no visible text):**
```json
{
"role": "assistant",
"content": null,
"tool_calls": [

How to install
mdr add agenttoolkit/altk-evolve/save-trajectory@sha256:84a064d1e5a5d7bfThe line at the top of this page pins the label git:20261021.2a75491, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
