Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00029 | $0.00291 |
| Opus 5 | $0.00015 | $0.00146 |
| Sonnet 5 | $0.00006 | $0.00058 |
| Haiku 4.5 | $0.00003 | $0.00029 |
Grade A, and why
release-preview scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
AgentOS Release Preview
AgentOS previews are branch snapshots from this repository. The workflow builds debug artifacts and publishes npm packages under a sanitized branch dist-tag. No crates.io release, git tag, or GitHub release is created.
agentos is a generated mirror. Do not bump a agentos ref or cut a agentos preview by hand.
Procedure
- Push the AgentOS branch.
- Dispatch and watch:
just release-preview <agentos-branch>
run=$(gh run list -R rivet-dev/agentos --workflow=publish.yaml -L1 --json databaseId --jq '.[0].databaseId')
gh run watch -R rivet-dev/agentos "$run" --exit-status
- Install a preview with:
npm install @rivet-dev/agentos-core@<sanitized-branch>
Rules
- Release-preview is for previews only; releases use the
releaseskill. - All code changes belong in AgentOS. The agentos mirror is regenerated from AgentOS and follows the published AgentOS version.
- On failure:
gh run view <run> --log-failed, fix, re-dispatch, re-watch.
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-preview is a skill published in the GitHub repository rivet-dev/agentos (4,444 stars, last pushed yesterday), licensed Apache-2.0. It adds 29 tokens to every session and 291 once invoked, about $0.0001 per session on Opus 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 2026-08-30.

update-changelog
Update docs/CHANGELOG.md from git history, GitHub releases, and code diffs. Use when: writing release notes, syncing the latest changelog entry, summarizing a new tag, or keeping changelog wording concise and consistent.
git-cleanup
Clean up local git branches and remotes accumulated from PR reviews. Use when the user asks to clean branches, remove stale remotes, or tidy up the local git state.
submit-pr-from-current-changes
Create a branch, commit existing local changes, push them, and open a pull request. Use when submitting current work as a PR.
pre-impl-discussion
Conduct a thorough pre-implementation discussion before making significant changes. Use when the user wants to discuss, plan, or evaluate a change before implementing it — especially when they say words like 'discuss', 'evaluate', 'plan', or 'let's talk about'.
gh-pr-description
