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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00099 | $0.02296 |
| Opus 5.5 | $0.00040 | $0.00918 |
| Sonnet 5.5 | $0.00020 | $0.00459 |
| Haiku 4.5 | $0.00010 | $0.00230 |
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.
How it starts
The opening of the file, as written. The whole thing — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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. Ownsapps/ui/src/data/changelog.json(full technical changelog) andapps/ui/src/core/whats-new/whats-new.json(in-app highlights).../Voiden Website/website— the public marketing site. Mirrors the technical changelog atsrc/features/changelog/data.ts, rendered bysrc/components/ChangelogEntry.tsx. Same content aschangelog.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.

release-changelog is a skill published in the GitHub repository VoidenHQ/voiden (1,867 stars, last pushed yesterday), licensed Apache-2.0. It adds 99 tokens to every session and 2,296 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-23.
