2026 OpenClaw Design Asset Pipeline: Reproducible Steps from Design Export to PNG Batch Rename on Remote Mac

OpenClaw’s Role in the Design Workflow

OpenClaw is an AI-driven automation layer that sits between your design tools and the final asset set. It helps with asset review, PNG processing, naming, and delivery. On a remote Mac it runs in a stable macOS environment with native design apps (Sketch, Figma desktop, Affinity, Adobe) and a Unix shell, so scripting and path handling are consistent. For designers and content ops, the value is a single, repeatable pipeline: design → export PNG → batch rename → validate → hand off to dev or CMS. OpenClaw does not replace your design tool; it standardizes what happens after export so every run produces the same structure and naming.

Install and Basic Config on Remote Mac

You need SSH (or VNC) access to the remote Mac. Then:

1. Environment: macOS 13+ recommended; install Xcode Command Line Tools (xcode-select --install), Python 3.10+ and Node 18+ if your pipeline uses them.
2. OpenClaw: Clone or install OpenClaw into a dedicated folder (e.g. ~/openclaw). Follow the official OpenClaw install guide for your platform.
3. Paths: Choose one export root directory (e.g. ~/DesignExports/png) and one output directory for renamed assets (e.g. ~/DesignExports/renamed). Create them and note the paths for the next steps.
4. Permissions: Ensure your user can read/write these folders and that any script or OpenClaw process will run with the same user (no permission denied when writing files).

After this, the remote Mac is ready for the export and rename steps.

Trigger Methods and Path Config for Exporting PNG from Design Files

PNG export can be triggered manually or automatically; the important part is that all PNGs land in one configured folder so the next step always knows where to look.

• Manual: In Figma, Sketch, or your design tool, set the export destination to the export root (e.g. ~/DesignExports/png). Export artboards or slices as PNG; leave files in that folder.
• Automated / scripted: If your tool supports CLI or plugins, trigger export via script and write to the same path. Some teams use cron or a small daemon that watches a “request” folder and runs an export job.
• Path config: In a small config file (e.g. config.json or env vars), set EXPORT_DIR and OUTPUT_DIR. Every script and OpenClaw skill should read from this so you can change paths in one place.

Example env-style config:

EXPORT_DIR=~/DesignExports/png
OUTPUT_DIR=~/DesignExports/renamed

Once exports always go to EXPORT_DIR, the batch rename step can assume that directory as input.

Batch Rename Rules and Script/Command Examples

Define one naming convention and apply it to every exported PNG so dev and CMS get predictable filenames.

Rules: Use lowercase, hyphens (no spaces), and include size when useful. Examples: hero-banner_1920x1080.png, icon-cta_64x64.png, category_assetname_800x600.png.

Example: rename by size (macOS sips + shell). The following assumes PNGs are in EXPORT_DIR; it renames each file to basename_WxH.png and writes into OUTPUT_DIR:

#!/bin/bash
EXPORT_DIR=~/DesignExports/png
OUTPUT_DIR=~/DesignExports/renamed
mkdir -p "$OUTPUT_DIR"
for f in "$EXPORT_DIR"/*.png; do
  [ -f "$f" ] || continue
  w=$(sips -g pixelWidth "$f" | awk '/pixelWidth/{print $2}')
  h=$(sips -g pixelHeight "$f" | awk '/pixelHeight/{print $2}')
  base=$(basename "$f" .png | tr '[:upper:]' '[:lower:]' | tr ' ' '-')
  cp "$f" "$OUTPUT_DIR/${base}_${w}x${h}.png"
done

Save as e.g. rename_by_size.sh, run chmod +x rename_by_size.sh, then execute from the remote Mac. For more complex rules (e.g. category from folder name, sequence numbers), extend the script or use an OpenClaw skill that implements the same logic.

Complete Reproducible Pipeline Steps

Run these in order for a full design-to-PNG pipeline that you can repeat anytime.

1. Export: In your design tool, export all needed artboards/slices as PNG into EXPORT_DIR (or trigger your automated export so files land there).
2. Rename: SSH into the remote Mac, cd to the folder containing your rename script or OpenClaw skill, and run it (e.g. ./rename_by_size.sh or the OpenClaw command). Confirm files appear in OUTPUT_DIR with the expected names.
3. Validate (optional): Run a size/spec check (e.g. min/max dimensions, file size) on OUTPUT_DIR. Move or report failures; fix and re-export if needed.
4. Hand off: Use OUTPUT_DIR as the single source for dev: copy to repo, upload to CDN, or import into CMS. Tag or version the folder if you need to track releases.

Common Errors and Permission Troubleshooting

Typical issues and how to fix them:

• Permission denied when writing: Check that EXPORT_DIR and OUTPUT_DIR are owned by the user running the script; run ls -la and fix with chmod or chown if needed. If using cron or a service, ensure it runs as that user.
• No such file or directory: Expand ~ to a full path in scripts (e.g. $HOME/DesignExports/png) so cron or non-interactive shells resolve paths correctly.
• sips / command not found: sips is built into macOS; if missing, confirm you are on a real Mac (or Mac VM). For ImageMagick-based scripts, install with brew install imagemagick.
• Empty export folder: Confirm the design tool is actually saving to EXPORT_DIR (check path in export settings). On a remote Mac, ensure the path is local to the Mac, not a network drive that might be unmounted.
• Overwriting files: If multiple exports produce the same base name, add a sequence or timestamp to the rename script to avoid overwriting (e.g. base_1920x1080_001.png).

After fixing, re-run from the export step so the whole pipeline stays in sync.
