openvidu.io: Skill for Claude Code

.claude/skills/blog-write/SKILL.md

blog-write is a skill for Claude Code from OpenVidu/openvidu.io. It costs 101 tokens per session (1,351 once invoked), scanned A, original, Apache-2.0.

A writing workflow for creating OpenVidu technical blog posts from a structured outline. It produces Markdown with the project's required metadata, headings, images, links, and copyable commands.

In plain words
What is it for?
Use it to write a complete post or selected sections, including an introduction, headings, search-focused content, calls to action, frontmatter, and technical examples.
Why use it?
It gives drafts a consistent structure and voice while checking the repository's publishing rules. An outline is required first; the planning workflow creates one when needed.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is OpenVidu/openvidu.io's own configuration. It tells Claude Code how to work on openvidu.io itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything openvidu.io configures →

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

blog-write 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 7d 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 — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.

OpenVidu Content Writer

Write a high-quality technical blog post from a provided outline. Draft in the outline's order, in one of two modes:

  • Full-post mode — produce the entire draft in one response.
  • Section mode — produce only the requested section(s), preserving continuity with surrounding context.

If no outline exists yet, use the blog-plan skill first.

Conventions (read first)

Read references/conventions.md before drafting — it is the single source for the naming invariant (file ↔ asset folder ↔ frontmatter agreement, the YYYY/MM draft mechanism), the full frontmatter template, the link rules (including the excerpt exception), registration, and the publish procedure. The allowed categories are read from categories_allowed in mkdocs.yml; author keys from docs/blog/.authors.yml.

Also read one or two recent posts in docs/blog/posts/ to match voice, depth, and formatting.

Post body structure

  1. H1 title (# ...) — matches the outline's title.
  2. Poster image immediately after the H1, using root-absolute asset paths (YYYY/MM stays literal while the post is a draft). Use light/dark variants when available:
    ![Descriptive alt text](/assets/images/blog/YYYY/MM/<slug>/poster-light.webp#only-light "title")
    ![Descriptive alt text](/assets/images/blog/YYYY/MM/<slug>/poster-dark.webp#only-dark "title")
    
    A single image can use { align=right width=60% } sizing attributes. Point cover_image at this poster too (a raster -light variant).
  3. Intro — first paragraph opens with a hook (a question or a clear benefit). It may run a little longer than body paragraphs.
  4. <!-- more --> on its own line immediately after the intro. This is mandatory — the blog plugin sets post_excerpt: required, so a missing tag breaks the build.
  5. H2/H3 sections following the outline, fundamentals → advanced.
  6. A closing "What to do next / Need more than this?" section linking to relevant OpenVidu docs and deployment types.

Changes

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.
