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.

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 | $0.00049 | $0.01228 |
| Opus 5 | $0.00024 | $0.00614 |
| Sonnet 5 | $0.00010 | $0.00246 |
| Haiku 4.5 | $0.00005 | $0.00123 |
Grade C, and why
hephaestus-cloud scanned grade C with 2 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 5d 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.
Downloads and executes remote codehighSupply chain
curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hephaestus Cloud Routing (my own cloud / 보관함)
Route the request through the signed-in user's OWN Agentlas cloud packages only. The active host LLM remains the staffing decision-maker; Cloud supplies a content menu and exact BYOM releases.
0. Scope rule
/hep-cloud is owner-scoped: it queries ONLY the authenticated owner's
own cloud packages (보관함) through Core's typed sourceScope: "cloud". It does not
search the public marketplace and does not search local private/plugin
cards.
- The user's own Cloud packages are restorable/owned by them. Entitlement, lease, and charged credits are server-authoritative; do not hard-code a price.
- For the public marketplace only, use
/hep-hub(sourceScope: "hub"). - For the combined Local + own Cloud + public Hub menu, use
/hep-network(sourceScope: "network").
Each unpinned Cloud discovery goes to the owner-scoped source for its current menu; a successful client cache entry must not hide a newly published, replaced, or removed package. Once the host validates and prepares a choice, the exact Cloud release remains pinned for that execution.
1. Resolve the runner
Run this resolution in a shell and use the first hit:
RUNNER=""
for c in \
"$HOME/.agentlas/runtime/current/bin/hephaestus" \
./bin/hephaestus
do [ -x "$c" ] && RUNNER="$c" && break; done
if [ -z "$RUNNER" ]; then
for cache in \
"$HOME/.claude/plugins/cache/agentlas-core-engine/hephaestus" \
"$HOME/.codex/plugins/cache/agentlas-core-engine/hephaestus"; do
newest="$(ls -d "$cache"/*/bin/hephaestus 2>/dev/null | sort -V | tail -1)"
[ -n "$newest" ] && [ -x "$newest" ] && RUNNER="$newest" && break
done
fi
If no runner exists, tell the user to run the one-touch installer:
curl -fsSL https://raw.githubusercontent.com/agentlas-ai/Agentlas-OS/main/scripts/install-all-runtimes.sh | bash
If shell execution is unavailable but the local hephaestus-network MCP is
available, use the typed Workforce sequence in section 3. If that server cannot
advertise owner-Cloud search plus exact bundle fetch, report
source_not_supported; never fall back to the legacy cargo search path.
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.

hephaestus-cloud is a skill published in the GitHub repository agentlas-ai/Agentlas-OS (1,101 stars, last pushed 3d ago), licensed Apache-2.0. It adds 49 tokens to every session and 1,228 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
