What it does
Managing Thumbnails is an agent skill from Comfy-Org/workflow_templates. Manages thumbnail and preview images for ComfyUI workflow templates. Adds, replaces, validates, and audits thumbnails. Use when asked to: add a thumbnail, replace a preview image, update template image, fix missing thumbnail, check thumbnails, audit thumbnails, which templates need thumbnails, missing previews, add preview image, change template picture, update template visual, swap thumbnail, set thumbnail, upload preview, template image missing, broken thumbnail, thumbnail not showing. Triggers on: thumbnail…
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in AI & LLM Engineering, covering Diffusion and image models. It works with ComfyUI. The repository describes itself as: ComfyUI template workflows. The licence is MIT.
When your agent uses it
- Asked to: add a thumbnail
- Replace a preview image
- Update template image
- Fix missing thumbnail
Example prompts
- “Use the managing-thumbnails skill to manage thumbnail and preview images for ComfyUI workflow templates”
- “/managing-thumbnails”
Requirements
- Python 3
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Name the file {template_name}-1.webp, where {template_name} matches the template's name field in templates/index.json.
- Place it in the templates/ directory.
- Compress to a reasonable size (use lossy webp compression, ~65% quality).
- If using compareSlider or hoverDissolve, also add {template_name}-2.webp.
What it can do on your machine
Read from SKILL.md and the folder at commit 8be1f8c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
pythonpnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pnpm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Managing Thumbnails loads about 1.1k tokens when it runs. Until then it costs about 161 tokens; SKILL.md has 410 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Manages thumbnail and preview images for ComfyUI workflow templates. Adds, replaces, validates, and audits thumbnails. Use when asked to: add a thumbnail, replace a preview image, update template image, fix missing thumbnail, check thumbnails, audit thumbnails, which templates need thumbnails, missing previews, add preview image, change template picture, update template visual, swap thumbnail, set thumbnail, upload preview, template image missing, broken thumbnail, thumbnail not showing. Triggers on: thumbnail, preview image, template image, template picture, missing thumbnail, add image, replace image, visual asset.
Managing Thumbnails
This skill covers adding, replacing, validating, and auditing thumbnail images for ComfyUI workflow templates.
Naming Convention
Thumbnails live in templates/ alongside the workflow JSON files. They are named using the template's name field from templates/index.json:
- Primary:
{template_name}-1.webp - Secondary (optional):
{template_name}-2.webp(only for dual-thumbnail variants)
The {template_name} portion must exactly match the name field in templates/index.json.
Supported Formats
| Format | Notes |
|---|---|
.webp | Preferred. Smallest file size. Use lossy compression (~65% quality). |
.png | Acceptable fallback. |
.jpg / .jpeg | Acceptable fallback. |
.webp (animated) | Used for video-type templates (animated webp). |
Thumbnail Variants
The thumbnailVariant field in templates/index.json controls how the thumbnail behaves on the site:
| Variant | Thumbnails Needed | Effect |
|---|---|---|
| (none/default) | -1 only | Static image, slight zoom on hover |
compareSlider | -1 AND -2 | Before/after slider comparison |
hoverDissolve | -1 AND -2 | Dissolves to second image on hover |
hoverZoom / zoomHover | -1 only | Same as default but zooms more |
If a template uses compareSlider or hoverDissolve, both -1 and -2 files are required.
Adding a Thumbnail
- Name the file
{template_name}-1.webp, where{template_name}matches the template'snamefield intemplates/index.json. - Place it in the
templates/directory. - Compress to a reasonable size (use lossy webp compression, ~65% quality).
- If using
compareSliderorhoverDissolve, also add{template_name}-2.webp.
Replacing a Thumbnail
Overwrite the existing file in templates/ with the new image, using the same filename.
Setting the Thumbnail Variant
Edit the template's entry in templates/index.json and set or change the thumbnailVariant field to one of: compareSlider, hoverDissolve, hoverZoom, or zoomHover. Remove the field (or leave it unset) for the default behavior.
Show full SKILL.md (157 more words)Show less
Auditing Thumbnails
Run the validation script to check for issues:
python scripts/validate/validate_thumbnails.pyThis checks for:
- Templates missing their primary thumbnail
- Templates with a dual-variant set (
compareSliderorhoverDissolve) but missing the second thumbnail (-2) - Orphaned thumbnail files not referenced by any template
Site Preview Images
The site also generates workflow preview images via:
pnpm run generate:previews # run from site/These are separate from template thumbnails — they are auto-generated visualizations of the workflow graph, not the output images you manage here.
Validation After Changes
After adding, replacing, or modifying thumbnails, always validate:
python scripts/validate/validate_thumbnails.py
python scripts/validate/validate_templates.pyThen sync to packages:
python scripts/sync/sync_bundles.pyRules
- The template name in the filename must exactly match the
namefield intemplates/index.json. - Always use
.webpformat when possible for smallest file size. - Thumbnails should ideally show the output produced by the workflow.
- If the template uses
compareSliderorhoverDissolve, both-1and-2files are required. - Never put thumbnails in
site/— they belong intemplates/. - After adding or changing thumbnails, run
python scripts/sync/sync_bundles.pyto sync to packages.
