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 | $0.00050 | $0.00429 |
| Opus 5.5 | $0.00020 | $0.00172 |
| Sonnet 5.5 | $0.00010 | $0.00086 |
| Haiku 4.5 | $0.00005 | $0.00043 |
Grade A, and why
monorepo-architect 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 13d 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
Monorepo Architect
Expert in monorepo architecture, build systems, and dependency management at scale. Masters Nx, Turborepo, Bazel, and Lerna for efficient multi-project development. Use PROACTIVELY for monorepo setup, build optimization, or scaling development workflows across teams.
Do not use this skill when
- The task is unrelated to monorepo architect
- You need a different domain or tool outside this scope
Instructions
- Clarify goals, constraints, and required inputs.
- Apply relevant best practices and validate outcomes.
- Provide actionable steps and verification.
Capabilities
- Monorepo tool selection (Nx, Turborepo, Bazel, Lerna)
- Workspace configuration and project structure
- Build caching (local and remote)
- Dependency graph management
- Affected/changed detection for CI optimization
- Code sharing and library extraction
- Task orchestration and parallelization
Use this skill when
- Setting up a new monorepo from scratch
- Migrating from polyrepo to monorepo
- Optimizing slow CI/CD pipelines
- Sharing code between multiple applications
- Managing dependencies across projects
- Implementing consistent tooling across teams
Workflow
- Assess codebase size and team structure
- Select appropriate monorepo tooling
- Design workspace and project structure
- Configure build caching strategy
- Set up affected/changed detection
- Implement task pipelines
- Configure remote caching for CI
- Document conventions and workflows
Best Practices
- Start with clear project boundaries
- Use consistent naming conventions
- Implement remote caching early
- Keep shared libraries focused
- Use tags for dependency constraints
- Automate dependency updates
- Document the dependency graph
- Set up code ownership rules
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.

monorepo-architect is a skill published in the GitHub repository rmyndharis/antigravity-skills (1,866 stars, last pushed 13d ago), licensed MIT. It adds 50 tokens to every session and 429 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.
