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 | $0.00066 | $0.00371 |
| Opus 5.5 | $0.00026 | $0.00148 |
| Sonnet 5.5 | $0.00013 | $0.00074 |
| Haiku 4.5 | $0.00007 | $0.00037 |
Grade A, and why
launch-graphics 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
agentOS launch graphics
Source generators live in docs-internal/graphics/ (committed). Rendered
PNGs go to ~/tmp/agentos-graphics/ — never commit output images.
Generate
node docs-internal/graphics/render-launch.mjs # launch/social hero → ~/tmp/agentos-graphics/launch.png
node docs-internal/graphics/render-technical.mjs # code-snippet card → ~/tmp/agentos-graphics/technical.png
- Pass an output dir as arg 1 to override (default
~/tmp/agentos-graphics/). render-technical.mjsneedsshiki(dev-only, not a repo dep): setSHIKI_DIR=/path/to/node_modules/shikiorpnpm add -D shiki.- After rendering, open the PNG to review before sharing.
Editing
- Read
docs-internal/graphics/README.mdfirst — it records the brand decisions (palette, fonts, "Apps" treatment, tile styling) to stay on. - Change layout/typography/snippets in the
render-*.mjsfiles orsnippets.json; keep new external logos vendored indocs-internal/graphics/assets/. - Iterate by re-running and viewing the PNG; tune sizes/spacing until it reads right.
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.

launch-graphics is a skill published in the GitHub repository rivet-dev/agentos (4,851 stars, last pushed yesterday), licensed Apache-2.0. It adds 66 tokens to every session and 371 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings.
