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.

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 | $0.00048 | $0.03774 |
| Opus 5 | $0.00024 | $0.01887 |
| Sonnet 5 | $0.00010 | $0.00755 |
| Haiku 4.5 | $0.00005 | $0.00377 |
Grade A, and why
comfy-debug-preview 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 today.
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 — 313 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ComfyUI debug & preview
Inspect values mid-graph without changing them. Read / log / visualize / time / report. Nothing in this skill mutates the data flow — these nodes either pass through unchanged (Preview Bridge, TimerNodeKJ) or are pure sinks (ShowText, CConsoleAny).
The split:
| Pack | Niche |
|---|---|
comfyui-custom-scripts (pysssss) |
ShowText — display text in node widget UI |
comfyui_essentials |
DisplayAny, ConsoleDebug, DebugTensorShape, BatchCount |
comfyui-kjnodes |
PreviewImageOrMask, FastPreview, VRAM_Debug, TimerNodeKJ, Sleep, Get(Image|Mask|Latent)SizeAndCount |
ComfyUI-Crystools |
CConsoleAny, CConsoleAnyToJson, CUtilsStatSystem (CPU/GPU/RAM monitor), CImageLoadWithMetadata, CMetadataExtractor, CMetadataCompare |
bjornulf_custom_nodes |
ShowFloat, ShowInt, ShowStringText, ShowJson, ImageDetails, VideoDetails |
comfyui-dream-project |
DreamStringToLog, DreamIntToLog, DreamFloatToLog, DreamJoinLog, DreamLogFile |
comfyui_yvann-nodes |
FloatsVisualizer (render a float array as a histogram image) |
comfyui-impact-pack |
Preview Bridge (Image) / Preview Bridge (Latent) — tee inspection while passing through |
comfyui-easy-use |
easy showAnything, easy showLoaderSettingsNames, imageCount, imagesCountInDirectory |

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.

comfy-debug-preview is a skill published in the GitHub repository laurigates/claude-plugins (57 stars, last pushed today), licensed MIT. It adds 48 tokens to every session and 3,774 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.

feature-branch-pr-writing
Use this skill when the user asks to write, draft, create, or improve a PR description for a Shopware core repository PR — AND that PR targets a non-trunk feature branch (not trunk itself). Trigger phrases like "write a PR description", "draft the PR", "what should I put in the PR body". The skill detects the target…
ci-log-interpretation
Use this skill when reading or analyzing CI logs from a Shopware GitHub Actions workflow to figure out why a build failed — phrases like "why did CI fail", "what broke the build", "check the pipeline", "interpret these logs", "debug this red build" — or whenever raw run logs, job logs, or check annotations from a…
a0-create-plugin
Create, extend, or modify Agent Zero plugins. Follows strict full-stack conventions (usr/plugins, plugin.yaml, Store Gating, AgentContext, plugin settings). Use for UI hooks, API handlers, lifecycle extensions, or plugin settings UI.
a0-contribute-plugin
Guide for publishing an Agent Zero plugin to the community Plugin Index (a0-plugins repo). Covers GitHub repo setup, index.yaml creation, CI validation rules, and PR submission. Use when the user wants to share, publish, submit, or contribute a plugin to the Plugin Hub so other Agent Zero users can find and install it.
repo-activity
Scan all git repositories under /repos and report recent activity — last commit age, branch, uncommitted changes — in age-bucketed tables. Use when the user asks for a repo activity overview, "what have I been working on", portfolio status, or which repos are active/dormant.
a0-plugin-router
Main entry point for all Agent Zero plugin tasks. Routes to specialist skills for creating, reviewing, contributing, managing, or debugging plugins. Use when the user mentions plugins, asks how the plugin system works, wants to build/install/uninstall/publish/debug a plugin, or asks about the Plugin Hub.
