DevVerse-SWE-Blog: Skill for Codex

.agents/skills/devverse-content-mdx/SKILL.md

devverse-content-mdx is a skill for Codex from hoangsonww/DevVerse-SWE-Blog. It costs 54 tokens per session (252 once invoked), scanned A, original, MIT.

A set of rules for writing and maintaining DevVerse articles stored as MDX, a Markdown format that can include code and structured metadata. It defines the article template, metadata, dates, headings, and checks needed by the site's content tools.

In plain words
What is it for?
Use it when adding or editing articles, metadata, authors, dates, or content-processing code. It also covers checking the content contract and optionally refreshing search vectors after edits.
Why use it?
It keeps article files compatible with the site's parsers, feeds, reading statistics, and retrieval system. It also requires dependent code to be updated when the article format changes.

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-content-mdx 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 3d 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 MDX Content Workflow

  1. Treat content/*.mdx as the canonical article store. Do not model article changes around supabase/articles.sql; runtime content comes from MDX files.

  2. Keep the article contract stable. Use a literal export const metadata = { title, description, topics };, keep ### Author: ..., keep > Date: YYYY-MM-DD, and keep the article body starting with a top-level # heading.

  3. Use the checked-in template when creating a new article. @assets/article-template.mdx

  4. Read the contract notes before changing metadata conventions. @references/article-contract.md

  5. If you change metadata shape or article template rules, update every dependent parser in the same task.

  6. After content edits, run python3 scripts/check_content_contract.py.

  7. If chat retrieval quality should reflect the change immediately, consider devverse-refresh-vectors.

Files

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.

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.
