What it does

Hephaestus Graph is an agent skill from agentlas-ai/Agentlas-OS. Use when the user types /hep-graph or asks to create, list, inspect, or request a run of an Agentlas automation graph.

Its SKILL.md is about 500 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows. The repository describes itself as: Agent OS: keep specialist agents in a hub, spin up a temporary orchestrator per task. Local-first, works with any model. The licence is Apache-2.0.

When your agent uses it

  • The user types /hep-graph
  • Request a run of an Agentlas automation graph

Example prompts

  • “/hephaestus-graph”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit cfdebf8. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Hephaestus Graph loads about 498 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 225 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~34
When it runs · the whole SKILL.md, loaded when a task matches
~498

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Hephaestus Graph

Saved graphs live in the local Agentlas database shared with Agentlas Desktop. This skill may create, list, inspect, or request a graph run; it does not execute the graph itself.

Resolve the independent Agentlas CLI

Use the first executable path:

bash
CLI=""
for candidate in \
  "$(command -v agentlas 2>/dev/null)" \
  "$HOME/.agentlas/runtime/current/bin/agentlas" \
  "./bin/agentlas"
do
  if [ -n "$candidate" ] && [ -x "$candidate" ]; then CLI="$candidate"; break; fi
done
[ -n "$CLI" ] || { echo "Agentlas CLI not found. Install it with: npm i -g agentlas" >&2; exit 1; }

Do not substitute Gemini CLI, Hephaestus routing, or Hub search when the Agentlas CLI is missing.

Commands

  • No arguments or list: run "$CLI" graph list and report each graph's trigger, step count, and on/off state.
  • show <name>: run "$CLI" graph show "<name>". Preserve the tree wiring, external-effect and ask-first marks, branch sides, repeat edges, verification checklist, code steps, and any required input in the summary.
  • new <request>: run "$CLI" graph new "<request>" as an interview. Relay every unanswered question and never invent schedule, external-effect, repetition, or checklist answers. The final save confirmation is the graph's approval. A new graph starts switched off.
  • run <name>: the user's direct run request is sufficient authority. Do not ask for a second approval. Show the graph first; if it requires an input, obtain that missing value without inventing it. Then run "$CLI" graph run "<name>" -y, adding --input "<value>" when required.

Report exactly that a run was requested and will be picked up by Agentlas Desktop. Never claim the graph executed. On any non-zero exit, relay the exact refusal and stop; do not retry with a guess.
