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: 4 findings, up to high
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 →
- high System Prompt Leakage · line 316 Skill contains instructions that could directly expose system prompts, internal rules, or hidden instructions to users or external parties.Fix: Remove any instructions that reveal, print, or output system prompts or internal rules.

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 | $0.00085 | $0.07083 |
| Opus 5 | $0.00043 | $0.03542 |
| Sonnet 5 | $0.00017 | $0.01417 |
| Haiku 4.5 | $0.00009 | $0.00708 |
Grade A, and why
comfyui-media-workflows 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 12d 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 — 596 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ComfyUI media workflow production
Use this skill to turn a creative or technical brief into a production-ready ComfyUI workflow package. Treat ComfyUI as a graph-based media production runtime, not as a prompt box. Your output should make the graph reproducible, reviewable, safe to run, and easy for another operator or system to execute.
This is provider-independent. Do not assume a specific checkpoint, hosted Comfy service, custom node set, or cloud vendor unless the user or the existing project explicitly names one. Re-check ComfyUI, custom-node, model, license, and cloud API facts at production time because they change frequently.
Operating principles
- Start from the deliverable and constraints, then choose graph topology, models, nodes, and runtime. Do not start by pasting a popular workflow.
- Separate documented facts from production heuristics. Documented facts come from current docs, model cards, licenses, API schemas, and direct tests. Heuristics are your production judgment.
- Keep two workflow artifacts when possible:
workflow.json: frontend/save-format graph with layout, grouping, notes, and operator readability.workflow_api.json: API-format graph for programmatic execution.
- Keep enough metadata to recreate a run: workflow JSON, input files with hashes, model identifiers and hashes, custom-node repo revisions, ComfyUI version, parameters, seed policy, hardware/runtime, output paths, and QA notes.
- Prefer fewer custom nodes and fewer model dependencies unless the creative requirement genuinely needs them. Every custom node is code execution and supply-chain risk.
- Never treat model availability as rights clearance. A file being downloadable does not mean the project can use it commercially, use its outputs freely, train on outputs, or use a person's likeness.
- Decide intentionally whether workflow metadata should be embedded in outputs. Embedded graphs aid reproducibility, but may leak prompts, model names, private paths, client references, API node titles, or workflow IP.
What ships with it
3 files 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-media-workflows is a skill published in the GitHub repository calesthio/generative-media-skills (170 stars, last pushed 1mo ago), licensed MIT. It adds 85 tokens to every session and 7,083 once invoked, about $0.0004 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 2026-08-30.
