cp-generate-segmentation-previews

cp-generate-segmentation-previews writes lightweight field-level preview PNGs.

It is the fast visual check step before you move on to heavier downstream work.

Purpose

Use this skill when you want:

  • quick PNG previews for the selected segmentation fields

  • a fast visual check before moving on to crops or feature extraction

  • a lightweight inspection step after cp-prepare-segmentation-inputs

Main Outcome

After this skill finishes, you have quick preview images that let you confirm the selected fields look usable.

This is a QC step. It does not create segmentation masks or single-cell crops.

Inputs

This skill reads:

  • a project config such as configs/project_config.demo.json

  • prepared segmentation inputs or a valid segmentation workflow root

  • the source channel paths needed to render the preview RGB images

  • an optional output directory

Outputs

  • sample_previews_png/*.png Field-level preview images for quick QC.

  • pipeline_skill_manifest.json The run record for this skill invocation.

Agent Demo

This page is based on a real local OpenClaw inspection of a completed preview result:

  • session id: segpreview-inspect-v1

  • recorded on 2026-05-06

  • model: vibe/gpt-5-mini

Request

I already have the demo preview images for this segmentation workflow. Please inspect the result under demo/workspace/outputs/agent_demo_segmentation/03_generate_previews_v7 and explain what these preview images let me check before moving on.

Structured Trace

user_input:
I already have the demo preview images for this segmentation workflow. Please inspect the result under demo/workspace/outputs/agent_demo_segmentation/03_generate_previews_v7 and explain what these preview images let me check before moving on.

recorded_turn:
- the saved OpenClaw turn answered this request directly
- the reply reported the two preview PNG files present in the directory
- the reply explained what these preview images can and cannot validate
- the reply framed them as a quick pre-segmentation visual sanity check

final_answer_snapshot:
The preview result contains two field-level images that let you check whether the selected fields look visually usable before moving on.

Demo Image

A01 sample preview

Caption: Field-level preview image for demo field BR00000001 / A01 / site 1, produced by cp-generate-segmentation-previews.

Observed Result

The inspected preview result contained:

  • sample_previews_png/BR00000001_A01_s1_sample.png

  • sample_previews_png/BR00000001_A02_s1_sample.png

So the completed preview set contained:

  • 2 field-level preview images

  • one image for A01

  • one image for A02

Recorded Reply

I inspected the existing preview result under:

- `demo/workspace/outputs/agent_demo_segmentation/03_generate_previews_v7`

### What preview outputs are there
This preview set contains:

- `sample_previews_png/BR00000001_A01_s1_sample.png`
- `sample_previews_png/BR00000001_A02_s1_sample.png`
