Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium MCP Rug Pull · line 99 Docker image references without a specific tag (:latest is implicit) or digest (@sha256:...) can be silently replaced by a malicious image.Fix: Pin the image: image:tag or image@sha256:abc123
- low Tool Misuse · line 99 Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00047 | $0.02175 |
| Opus 5 | $0.00023 | $0.01087 |
| Sonnet 5 | $0.00009 | $0.00435 |
| Haiku 4.5 | $0.00005 | $0.00217 |
Grade A, and why
comfyui-screenshot-pipeline scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 142 lines — stays where its author put it; the contents beside it link to each section on GitHub.
comfyui-screenshot-pipeline
Add the containerized README-screenshot generator to a ComfyUI usability pack.
It is the deferred piece from comfyui-node-scaffold (which intentionally does
not emit it). The same pattern ships in comfyui-gallery-loader,
comfyui-sampler-info, comfyui-touch-numeric, comfyui-prompt-editor,
comfyui-model-gallery, comfyui-touch-resize, and comfyui-touch-connect —
those are the living reference implementations.
When to Use This Skill
| Use this skill when... | Use the alternative when... |
|---|---|
Adding a reproducible README-screenshot generator to an existing ComfyUI pack — Docker + Playwright driver, just screenshots, committed docs/<out>.png |
Bootstrapping a brand-new pack repo → comfyui-node-scaffold (it intentionally defers the screenshot pipeline) |
| Capturing the pack's real frontend deterministically (modal dialog, gesture affordance, or transient overlay) | Running the full idea→registry lifecycle → comfy-node |
Why containerized
The shot must not depend on whatever models / theme / frontend a dev machine
happens to have. A Docker image pins the ComfyUI release (hence the frontend
bundle) and the Playwright/Chromium revision (the largest source of cross-host
font-rendering drift), boots ComfyUI headless on CPU with no models, drives the
pack's real public surface, and writes a PNG to a mounted docs/. Re-runs are
deterministic.
Pick the archetype
| Archetype | Use when the pack… | What the driver does |
|---|---|---|
modal |
opens an HTML dialog over a widget (the modal "vein": gallery-loader, sampler-info, touch-numeric, prompt-editor, model-gallery) | load a workflow with the target node, wait for the pack's patch flag on the widget, invoke widget.onPointerDown, wait for .cmp-dialog, screenshot it |
gesture-affordance |
is a canvas gesture whose only static surface is a painted affordance (touch-resize's corner-hint bracket) | select a node directly (no selectNode → no Vue toolbox) so onDrawForeground paints, optionally inject an illustrative callout overlay, clip the canvas region around the node |
gesture-overlay |
shows a transient overlay only during a live gesture that can't run headlessly (touch-connect's magnifier loupe) | force the canvas state (connecting_links etc.), dispatch a synthetic touch pointer the pack listens for, then screenshot the activated overlay element |
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

comfyui-screenshot-pipeline is a skill published in the GitHub repository laurigates/claude-plugins (58 stars, last pushed 2d ago), licensed MIT. It adds 47 tokens to every session and 2,175 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
