voiden: Skill for Claude Code

.agents/skills/release-changelog/SKILL.md

release-changelog is a skill for Claude Code, Codex from VoidenHQ/voiden. It costs 99 tokens per session (2,296 once invoked), scanned A, original, Apache-2.0.

A release-changelog workflow for keeping an app's technical changelog, in-app highlights, and public website copy aligned. It also checks whether user-facing changes may need documentation updates.

In plain words
What is it for?
Use it when creating a new Voiden app release entry or synchronising the marketing website's changelog. It covers release notes and related documentation checks.
Why use it?
It reduces the chance that a release is documented in one repository but missing or outdated in another. It treats the app, website, and documentation as separate places that may need coordinated updates.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is VoidenHQ/voiden's own configuration. It tells Claude Code and Codex how to work on voiden 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 voiden configures →

About the project

Voiden is an offline API workspace that stores requests, tests, documentation, and reusable API components in plain-text Markdown-based files managed with Git. Developers, QA engineers, and technical writers use it to build, test, document, script, and collaborate on APIs.

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-changelog 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 27d 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.

Voiden release changelog workflow

Sibling repositories

This repo (voiden) is one of three under ~/Desktop/Voiden/ — know all three before starting release work, since a release routinely touches more than one:

  • voiden (this repo) — the app monorepo. Owns apps/ui/src/data/changelog.json (full technical changelog) and apps/ui/src/core/whats-new/whats-new.json (in-app highlights).
  • ../Voiden Website/website — the public marketing site. Mirrors the technical changelog at src/features/changelog/data.ts, rendered by src/components/ChangelogEntry.tsx. Same content as changelog.json, different schema (see part 3 below) — keep both in sync every release, don't let the website fall behind (it had silently missed three whole releases before this note existed).
  • ../docs — the docs site (docs.voiden.md, Docusaurus). No changelog here, but a release that adds or changes a user-facing feature (a new block, a new CLI flag, a new panel) usually means a doc page needs updating too. This skill doesn't write those doc edits itself — but check whether one's needed, and say so, rather than closing out release work as if the changelog were the only thing that could be stale.

When asked to create a changelog entry for a new app version, three files across two repos need updating, not one. They serve different audiences and have different formats — do not skip any of them or copy the same content in verbatim where the format actually differs.

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.
