agentOS is a library that lets software agents run inside an existing application backend, using WebAssembly and V8 isolates with controlled access to host resources. It is for developers building agent-powered backends who need embedded execution and permissions, while the catalogue entries provide skills and instructions for operating the framework.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00032 | $0.00222 |
| Opus 5.5 | $0.00013 | $0.00089 |
| Sonnet 5.5 | $0.00006 | $0.00044 |
| Haiku 4.5 | $0.00003 | $0.00022 |
Grade A, and why
publish-registry 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 2mo 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
Publish AgentOS Registry Packages
Registry packages live in agentos/registry and publish as
@agentos-software/*. They version independently per package.
Procedure
- Build native command artifacts and package tarballs:
just registry-native
just registry-build [pkg]
just registry-status --remote
- Bump the package's own
package.jsonversion and commit it. - Publish from AgentOS:
just registry-publish <pkg> # dist-tag dev
just registry-publish <pkg> latest # deliberate latest release
just registry-publish-all [tag]
Rules
- Do not publish registry packages from agentos.
- Do not move
latestunless the user explicitly asks for a release. - Prefer AgentOS workspace builds while iterating; published pins are for consumers and release validation.
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.

publish-registry is a skill published in the GitHub repository rivet-dev/agentos (4,851 stars, last pushed yesterday), licensed Apache-2.0. It adds 32 tokens to every session and 222 once invoked, about $0.0001 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 2026-08-30.
