vertex-agent-skill

vertex-agent-skill is a skill for Claude Code from zeenie-ai/OpenCompany. It costs 61 tokens per session (494 once invoked), scanned A, original, MIT.

A delegation tool that sends a task to a Google-hosted managed agent running in an isolated Linux environment.

In plain words
What is it for?
Delegate multi-step research, data processing, code or file generation, and other long-running jobs to a cloud agent, then check their results.
Why use it?
It lets longer research or computing jobs run separately from the local machine, with access to code execution, files, web search, and URL fetching.

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

vertex-agent-skill 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 9d 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

Vertex Managed Agent Skill

Delegate work to Google's managed agent (the Antigravity harness on the Gemini Enterprise Agent Platform). The agent runs entirely in Google's cloud inside an isolated Linux sandbox with Python 3.11, Node.js, bash, file management, Google Search, and URL fetching.

Tool: delegate_to_vertex_managed_agent

Non-blocking delegation. Two fields:

Field Purpose
task What the cloud agent should accomplish — its system instruction for the run
context Optional background, inputs, or data the agent needs

The call returns immediately with {"status": "delegated", "task_id": ...}. Use check_delegated_tasks to poll for the result — do NOT re-delegate the same task while one is in flight.

When to delegate to the cloud agent

  • Multi-step research: search the web, fetch pages, synthesize a report.
  • Compute jobs: run Python/Node code, process data, generate files — all inside the cloud sandbox, not on this machine.
  • Long-running work you want isolated from the local workflow.

Prefer LOCAL tools (python_executor, shell, file tools) when the work needs files in this workflow's workspace — the cloud sandbox cannot see local files unless their content is passed in context.

Behavior notes

  • The cloud agent keeps its own multi-turn state: when a simpleMemory node is connected to the Vertex Agent, conversation and sandbox (installed packages, created files) persist across runs for up to 7 days.
  • Cloud-side tool usage (sandbox commands, searches) appears on the canvas as Cloud Tool nodes wired to the Vertex Agent — they are display-only indicators, safe to delete.
  • Task descriptions should be self-contained: the cloud agent cannot ask you follow-up questions mid-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.
