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
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.

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 | $0.00013 | $0.01073 |
| Opus 5.5 | $0.00005 | $0.00429 |
| Sonnet 5.5 | $0.00003 | $0.00215 |
| Haiku 4.5 | $0.00001 | $0.00107 |
Grade A, and why
hep-call 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 1mo 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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Update fallback: 자동 업데이트가 안 되면 hephaestus update를 한 번 실행하세요. 업데이트하지 않아도 현재 버전 명령은 그대로 동작합니다.
/hep-call
Call the exact agents named by the user. This prepares BYOM runtime bundles and receipts; your own model still performs the actual model/tool execution.
Syntax: /hep-call agent-a, agent-b {context}. The text before { is the
agent list; the text inside braces is the context. If braces are omitted, the
first token is the agent list and the rest is context.
If the user wants it to keep running
Public Hub agent calls are free. Explain that scheduled work still uses the host's own model, API keys, permissions, and runtime capacity. Do not quote or purchase a retired Hub lease.
How to run
Run the shell block below verbatim, replacing only the RAW value with the
exact text the user typed after /hep-call. The runner is resolved by
absolute path — nothing to install, nothing to add to PATH.
Guardrails: do NOT diagnose
command not found/PATH, do NOT edit~/.zshrc, and do NOT create/commit/stash/push any git branch or claim you did. This workflow changes no source files. If the runner is missing, say so and stop — never fabricate a run.

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-call is a skill published in the GitHub repository agentlas-ai/Agentlas-OS (1,587 stars, last pushed today), licensed Apache-2.0. It adds 13 tokens to every session and 1,073 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 2026-09-03.
