vertex-tuning

vertex-tuning is a skill for Claude Code, Codex from GoogleCloudPlatform/vertex-ai-samples. It costs 0 tokens per session (444 once invoked), scanned A, original, Apache-2.0.

A routing guide for fine-tuning models in Vertex AI, Google Cloud’s platform for building and using machine-learning models.

In plain words
What is it for?
It identifies whether the user wants to tune an open model or a Gemini model, then sends the task to the matching workflow.
Why use it?
It prevents the wrong tuning instructions from being used because open models and Gemini models require different procedures.

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-tuning 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 6d ago.

The scan reads SKILL.md. This mod also ships 7 executable files (open-model/scripts/calculate_cost.py, open-model/scripts/deploy_open_model.py, open-model/scripts/prepare_dataset.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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


name: vertex-tuning description: > Vertex AI Model Tuning Router. Use this skill when the user wants to fine-tune models using Vertex AI. This skill routes to either vertex-tuning-open-model or vertex-tuning-gemini.

Vertex AI Model Tuning (Router)

Overview

This skill acts as a router for Vertex AI tuning tasks. The tuning procedures for Open Models and Gemini Models differ significantly. Your first step is to determine which category the user intends to tune and then read the corresponding sub-skill.

Workflow Decision Tree

  1. Model Category: Has the user explicitly stated whether they want to tune an Open Model or a Gemini Model?

    • NoSTOP. Ask the user if they want to tune an Open Model or a Gemini Model. Do not proceed or recommend any specific models until this is confirmed.
    • Yes (Open Model) → The user wants to tune an Open Model. Stop reading this file and IMMEDIATELY read the skill instructions located at open-model/SKILL.md. Follow the instructions inside that skill to complete the task.
    • Yes (Gemini Model) → The user wants to tune a Gemini Model. Stop reading this file and IMMEDIATELY read the skill instructions located at gemini/SKILL.md. Follow the instructions inside that skill to complete the task.

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.

vertex-tuning is a skill published in the GitHub repository GoogleCloudPlatform/vertex-ai-samples (784 stars, last pushed today), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 444 tokens. 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 2026-08-30.
