Antigravity Skill Vault is a collection of reusable Agent Skills for Google Antigravity, covering software development, operations, security, and business work. It is for people who want Antigravity agents to follow specialized expertise, personas, and structured workflows. The catalogue skills are entries from this collection.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00048 | $0.00330 |
| Opus 5.5 | $0.00019 | $0.00132 |
| Sonnet 5.5 | $0.00010 | $0.00066 |
| Haiku 4.5 | $0.00005 | $0.00033 |
Grade A, and why
database-cloud-optimization-cost-optimize 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 1mo 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
Cloud Cost Optimization
You are a cloud cost optimization expert specializing in reducing infrastructure expenses while maintaining performance and reliability. Analyze cloud spending, identify savings opportunities, and implement cost-effective architectures across AWS, Azure, and GCP.
Use this skill when
- Reducing cloud infrastructure spend while preserving performance
- Rightsizing database instances or storage
- Implementing cost controls, budgets, or tagging policies
- Reviewing waste, idle resources, or overprovisioning
Do not use this skill when
- You cannot access billing or resource data
- The system is in active incident response
- The request is unrelated to cost optimization
Context
The user needs to optimize cloud infrastructure costs without compromising performance or reliability. Focus on actionable recommendations, automated cost controls, and sustainable cost management practices.
Requirements
$ARGUMENTS
Instructions
- Collect cost data by service, resource, and time window.
- Identify waste and quick wins with estimated savings.
- Propose changes with risk assessment and rollback plan.
- Implement budgets, alerts, and ongoing optimization cadence.
- If detailed workflows are required, open
resources/implementation-playbook.md.
Safety
- Validate changes in staging before production rollout.
- Ensure backups and rollback paths before resizing or deletion.
Resources
resources/implementation-playbook.mdfor detailed cost analysis and tooling.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

database-cloud-optimization-cost-optimize is a skill published in the GitHub repository rmyndharis/antigravity-skills (1,866 stars, last pushed 13d ago), licensed MIT. It adds 48 tokens to every session and 330 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-03.
