DevVerse-SWE-Blog: Skill for Codex

.agents/skills/devverse-feeds-seo/SKILL.md

devverse-feeds-seo is a skill for Codex from hoangsonww/DevVerse-SWE-Blog. It costs 58 tokens per session (202 once invoked), scanned A, original, MIT.

Project-specific guidance for maintaining DevVerse feeds, sitemaps, metadata, manifests, robots files, and related publishing code. A sitemap helps search engines find a site's pages, while metadata describes pages in browsers and search results.

In plain words
What is it for?
Use it when editing RSS or JSON feeds, sitemap configuration, page metadata, manifests, robots files, or the site's publishing parser.
Why use it?
It helps keep public URLs and shared article data consistent when changing feeds or search-related site settings.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is hoangsonww/DevVerse-SWE-Blog's own configuration. It tells Codex how to work on DevVerse-SWE-Blog 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 DevVerse-SWE-Blog 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

devverse-feeds-seo 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 4d 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.

What it actually says

DevVerse Feeds And SEO Workflow

  1. Treat lib/rss.ts as the central publishing parser. Home page data, feeds, related posts, excerpts, and reading stats all depend on it.

  2. Preserve the current public URL assumptions. Feeds and local RAG use NEXT_PUBLIC_SITE_URL, while sitemap uses SITE_URL.

  3. Read the publishing notes before changing metadata or feed generation. @references/publishing-notes.md

  4. If you change article metadata parsing in lib/rss.ts, check the MDX contract and update dependent code as needed.

  5. After meaningful changes here, prefer devverse-validate and consider npm run build.

Files

What ships with it

2 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.

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.
