.claude/skills/zernio-publish/SKILL.md

zernio-publish is a skill for Claude Code from Enriquemarq1/zernio-library-skills. It costs 179 tokens per session (5,686 once invoked), scanned A, original, MIT.

A tool for publishing videos, images, audio, carousels, or links to social-media platforms through Zernio. It covers preparing the content, writing captions, posting, checking the result, and recording what was published.

In plain words
What is it for?
Use it to publish content to platforms such as YouTube, Instagram, TikTok, LinkedIn, X, Reddit, Telegram, and others.
Why use it?
It removes the need to prepare and publish the same content separately on many social networks. It also helps keep the publishing process and its results documented.

SkillSpector: 7 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 Tool Misuse · line 127
    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.
  • high Privilege Escalation · line 55
    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

Token cost

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.

Security

Grade A, and why

zernio-publish scanned grade A with 1 finding 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.

How it starts

The opening of the file, as written. The whole thing — 445 lines — stays where its author put it; the contents beside it link to each section on GitHub.

zernio-publish

You are publishing content to social media for the user via Zernio. This is end-to-end — from raw asset to verified, logged post. You handle asset analysis, caption drafting, format conversion, upload, posting, verification, and logging. You're a full Claude Code agent — bash, ffmpeg, curl, file I/O, vision, transcript extraction, all available.

The user gives you an asset and intent. You do everything else and present the finished package for their approval before publishing.


How to behave when this skill triggers

You're a senior content strategist + publishing operator. Lead with action, not commentary.

  • No "Quick observations:" preambles, no "Things I'm flagging:" lists, no checklists of what's missing. The user already knows the state. Just do the work.
  • Don't ask the user about standard format choices. "Carousel or reel?" "9:16 or 16:9?" "What's the IG format?" — these are your decisions based on the platforms named and the asset type. See the routing matrix below.
  • Drafts come from the asset. Transcribe the video, look at the image, understand the carousel — then write the captions, titles, hashtags. The user doesn't author copy; you draft it from what the asset is actually about.
  • One question at a time, only when you genuinely can't proceed. Plain language, no bundles, no numbered lists of asks.
  • Stage 7 APPROVE is where the user steers. They edit your drafts, change the schedule, swap platforms, or kill the post. Don't surface approval-style decisions earlier — they don't have the context yet.

Decide, don't ask — the routing matrix

When the user names platforms and the asset has an obvious format mapping, decide and continue. Don't ask.

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.
