Agentlas OS is a local-first system for creating, storing, borrowing, and running specialist AI agents and temporary agent teams through supported hosts and models. It serves people who want reusable agents that remain available across computers and model workspaces, and the catalogue contains its skills, commands, hooks, agents, instructions, plugin, and rule.
Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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 | $0.00000 | $0.01760 |
| Opus 5 | $0.00000 | $0.00880 |
| Sonnet 5 | $0.00000 | $0.00352 |
| Haiku 4.5 | $0.00000 | $0.00176 |
Grade A, and why
hep-browser.body 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 4d 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.
This is a copy
91% identical to hep-browser — 17 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/hep-browser
Use this when the task needs a real browser, page rendering, login-visible state, click/form behavior, or JS-heavy evidence. Prefer the Agentlas browser hardpoint first; do not route browser work through generic research commands unless this command reports that the hardpoint is unavailable.
Behavior:
/hep-browser <url>reads a rendered browser snapshot./hep-browser <url> "<instruction>"or/hep-browser <url> --act "<instruction>"performs browser automation throughbrowser.agent_cli, then captures a snapshot.- If the Agentlas Browser CDP port is already live, the command attaches to it by default so logged-in Desktop/browser state is reused.
- Prefer the human-facing URL a person would type over app-shell automation
URLs. For example, use
https://mail.google.com/instead ofhttps://mail.google.com/mail/u/0/#inboxunless that exact deep route is required. Add--raw-urlto preserve the exact URL. /hep-browser <url> --click @e1clicks an explicit snapshot ref./hep-browser <url> --click-text "Compose"clicks visible text without an LLM provider.- Add
--wait-ms 2000when a dynamic app opens dialogs after a short delay. - Add
--readto force snapshot-only mode when extra text is context rather than an action. - Pass
--cdp,--profile,--auto-connect, or--headedonly when the user needs an existing Desktop/browser session or a specific browser launch mode.

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.

hep-browser.body is a command published in the GitHub repository agentlas-ai/Agentlas-OS (1,103 stars, last pushed yesterday), licensed Apache-2.0.
