hep-call

hep-call is a skill for Claude Code from agentlas-ai/Agentlas-OS. It costs 13 tokens per session (458 once invoked), scanned A, original, Apache-2.0.

An agent-preparation skill for explicitly named Agentlas Cloud or Hub agents. It prepares the named agents for a request but does not itself describe broader discovery.

In plain words
What is it for?
Use it when you already know which Agentlas agents should handle a task and want to provide them with shared context.
Why use it?
It turns exact agent names or slugs into a prepared execution request while retaining their source and identity details.

Skill for Claude Code

Written for Claude Code: $ARGUMENTS substitution. Also seen: mentions Codex.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is for c in "$HOME/.agentlas/runtime/current/bin/hephaestus" ./bin/hephaestus; do.

Good fit Use it when you already know which Agentlas agents should handle a task and want to provide them with shared context.

About the project

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

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

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.

Security

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 7d 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

Update fallback: 자동 업데이트가 안 되면 hephaestus update를 한 번 실행하세요. 업데이트하지 않아도 현재 버전 명령은 그대로 동작합니다.

Hephaestus Call

Raw arguments: everything the user typed after /skill:hep-call.

Codex plugins cannot register slash commands, so this custom prompt is the explicit entrypoint: /prompts:hep-call.

  1. Resolve the runner and prepare the named agents:
RUNNER=""
for c in "$HOME/.agentlas/runtime/current/bin/hephaestus" ./bin/hephaestus; do
  [ -x "$c" ] && RUNNER="$c" && break
done
[ -n "$RUNNER" ] || { echo "Hephaestus runtime not found. Run the installer first." >&2; exit 1; }
if [ "${HEPHAESTUS_AUTH_AUTOPOPUP:-1}" != "0" ]; then
  "$RUNNER" auth ensure --timeout 180 >/dev/null 2>&1 || true
fi
RAW="$ARGUMENTS"
if printf '%s' "$RAW" | grep -q '{'; then
  AGENTS="${RAW%%\{*}"
  CONTEXT="${RAW#*\{}"
  CONTEXT="${CONTEXT%\}}"
else
  AGENTS="${RAW%% *}"
  CONTEXT="${RAW#* }"
fi
AGENTS="$(printf '%s' "$AGENTS" | sed 's/[[:space:]]*$//')"
CONTEXT="$(printf '%s' "$CONTEXT" | sed 's/^[[:space:]]*//;s/[[:space:]]*$//')"
"$RUNNER" call "$AGENTS" "$CONTEXT" --runtime codex
  1. For each prepared agent, follow its returned output.entry_excerpt and output.grounding.directive. The Hub returns BYOM instructions; Codex executes with the current model and permission model.

  2. Report failures separately and include the top-level receipt_id plus every prepared agent execution_id.

Changes

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.
