neva: Skill for Codex

.codex/skills/release-discord-post/SKILL.md

release-discord-post is a skill for Codex from nevalang/neva. It costs 29 tokens per session (462 once invoked), scanned A, original, MIT.

A writing workflow that turns GitHub release details into a concise announcement for a Neva Discord news channel. It selects highlights, adds the release link, and uses plain text or light Markdown.

In plain words
What is it for?
Use it to announce software releases in Discord with a short introduction, a list of changes, and a link to the full release notes.
Why use it?
It removes the need to adapt technical release notes into a readable community announcement by hand. It also keeps the message grounded in the changes that actually shipped.

About the project

Neva is a statically typed programming language in which programs are message-passing graphs: nodes exchange data through ports and run concurrently by default. It is for developers building compiled programs with dataflow control, visual editing, and interoperability with Go. The catalogue includes skills and instructions for working with Neva.

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 →

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

release-discord-post 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.

What it actually says

Release Discord Post

Create a Discord-ready release announcement in English for the target Neva Discord news-style channel provided by the caller.

Workflow

  1. Read the release context from the prompt: repository, target channel name, tag, release name, release URL, and release notes.
  2. Read .codex/shared/release-marketing.md for positioning, CTA, and tone guidance.
  3. Produce a concise Discord post in English using this high-level structure:
    • Line 1: release heading like Neva vX.Y.Z or Neva vX.Y.Z - Release Title
    • Optional short punchy framing line when the release has a clear theme
    • Short intro paragraph, 1-2 sentences max
    • Highlights or What shipped label
    • 4-8 short bullet lines with the most relevant release changes
    • Full notes: label or short CTA line
    • Final line: release URL by itself
  4. Keep the intro and bullets grounded in the actual release notes. If the notes are sparse, stay conservative and do not invent features or guarantees.
  5. Optimize for Discord readability: plain text or light Markdown, short paragraphs, scannable bullets, no Telegram-style HTML.
  6. Keep the tone clear, sharp, mildly energetic, and community-facing. Avoid corporate phrasing and overselling.
  7. Use @everyone only when the caller explicitly asks for it.
  8. Keep the message under 1800 characters.
  9. Save output to the exact file path requested by the caller.

Output Rules

  • Return only the final Discord message body in the file.
  • Do not add wrappers like "Here is your post", "Result:", or "Output:".
  • Do not add YAML frontmatter, surrounding quotes, or code fences.
  • Do not bury the release URL inside another sentence; keep it on its own final line.
  • Prefer short, high-signal bullets over exhaustive coverage of every patch note.
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.
